Installation of pneuma suspension on Priora

The front suspension of the VAZ 2170 is an independent MacPherson strut. The basis of the car suspension is a telescopic shock absorber strut. The front suspension of the serial car Lada Priora is independent with hydraulic shock absorbers. The shock absorbers are equipped with barrel-shaped coil springs.

The device of the regular suspension of the car Lada Priora

The main suspension element of a Lada Priora passenger car is a hydraulic strut, which is connected by its lower part to a special turning element - a fist. The telescopic strut is fitted with a spring, polyurethane compression damper and strut support.

The bracket is attached with 3 nuts to the rack. Due to the presence of a high degree of elasticity, the bracket can balance the rack during the working stroke of the automatic suspension and dampen vibrations. The bearing built into the support allows the rack to rotate simultaneously with the wheels.

The lower part of the steering knuckle is combined with a ball joint and a suspension arm. The forces acting on the suspension are transmitted by splines, which on the Priore are connected by silent blocks with levers and front supports. Adjusting washers are installed at the attachment points of the splines, lever and front bracket.

With the help of the latter, the angle of inclination of the axis of rotation is adjusted. The rotary cam provides for the installation of a closed type bearing. A wheel hub is mounted on the inner rings of the bearing. The bearing is tightened with a nut on a rod located in the Lada Priora wheel gear and cannot be adjusted. All hub nuts are interchangeable and have right hand threads.

Priora's independent suspension has an anti-roll bar, which is a bar. The knees of the bar are attached to the levers at the bottom with zippers with rubber and metal loops. The torsion element is attached to the body of the Lada Priora using special brackets through rubber cushions.

In addition to hydraulic suspension, today manufacturers produce another type of Priora suspension - pneumatic. Before you start talking about replacing the standard hydraulic suspension with the Lada Priora air suspension, you need to choose the right air springs and shock absorbers.

The springs are a special shock absorber, the function of which is to dampen the vibrations that occur in the suspension when it comes into contact with the road. If you choose the right air suspension springs for Priora, you can not be afraid of suspension breakdowns when hitting potholes if the road is not smooth.

Very often, in the process of tuning Lada Priora, a screw suspension is used to equip a car, which is a type of air suspension. This type of front suspension does not have good protection against road dust and dirt on the shock rods, which act as a good abrasive on the guide bushings, causing the shock absorbers to fail and seize.

One of these breakdowns, which manifests itself most often, is a blow to the front suspension. Also, this malfunction is the most common and can occur when Priora silent blocks are worn out.

Suspension failure can have unpredictable consequences while driving, so the appearance of such a symptom as a knock in the front suspension requires almost immediate intervention in the design and repair. In the process of repairing the suspension, wear of the Priora silent blocks can be detected. If such a malfunction is detected, in order to avoid creating an emergency, replacement of silent blocks is required.

The choice of shock absorbers for mounting air suspension on Priora

The manufacturer produces and sells several varieties of structurally different shock absorbers for mounting air suspension on Priora. When choosing a shock absorber for Priora, you should pay attention to the advice of experts who really understand the design features of various shock absorbers. The Priora independent suspension is mounted on the basis of three types of shock absorbers:

• butter;
• high pressure gas;
• gas, low pressure.

The Priora independent suspension, with the wrong choice of shock absorber, is not able to work effectively and compensate for vibrations upon contact with the road. With the right selection of shock absorbers, the Priora independent suspension is able to almost completely compensate for the shocks received by the car from bumps and potholes on the road. The dynamics of the car Lada Priora will increase significantly, and driving comfort will improve.

After replacing the springs and shock absorbers, the Priora independent suspension requires high-quality settings. The process of adjusting the new suspension installed on the Lada Priora includes a reduction in unsprung masses and ground clearance.

The main characteristics of the air suspension on the Lada Priora

The suspension kit has the ability to change its value in a range equal to the stroke of the installed shock absorbers. For the implementation of pneumatization of shock absorbers, a sleeve method is used. Installation of air suspension parts on Priora is carried out by replacing standard spring elements. The assembly of the air suspension structure of the car is carried out using cables with a diameter of 6 mm.

For the operation of the car suspension, a compressor and a receiver with a volume of 8 liters are installed. On some models, the Priora independent suspension is equipped with a 10-liter receiver compressor. This Lada suspension has a reaction time of about 4 seconds. The principle of control is manual, and control is carried out using pressure gauges. Four-circuit control (separate for the front and rear axles, as well as for the right and left sides of the car).

As a rule, the Priora air suspension is equipped with such options as tire inflation, pneumatic signal and an intermediate axle. In addition, the Priora independent suspension can be equipped with a remote control and a command controller.

The main advantages of mounting an air suspension

Installing an air suspension on a Lada Priora car instead of a standard factory hydraulic suspension is a change in the factory design of the car, i.e. suspension tuning. The installation of such a car suspension design allows the Lada Priora suspension to perfectly absorb bumps and potholes on the road while the car is moving. A car with air suspension in its equipment becomes more stable on the track.

At the same time, the installation of air suspension on the car can improve the dynamic qualities of the car. The rear independent suspension installed on the car, along with the front independent suspension installed, allows you to get a large number of advantages, which are expressed in the following:

1. The independent suspension installed on the Priora reduces the lateral roll of the car when the passenger compartment is unevenly loaded.
2. Installing air suspension on Priora allows you to reduce the load on the suspension elements, thereby significantly increasing their service life.
3. Driving a Lada Priora with independent air suspension installed allows you to achieve a more comfortable ride on roads with different road surface quality.
4. Priora independent suspension allows you to increase the degree of vehicle stability when cornering on the road while driving.
5. Installing air suspension on Priora allows you to reduce the negative impact on the car during overload.
6. The independent suspension installed on the Priora eliminates the possibility of the car tipping over when driving off-road.

Installing air suspension on Priora allows the driver to independently control and change, if necessary, the vehicle's ground clearance, taking into account the quality of the road surface and the load on the vehicle's suspension.

Feedback from motorists who decide to make a change in the design of the car and replace the standard suspension with air suspension, as a rule, turns out to be positive, since the use of air suspension allows you to get a number of advantages in operation.

Set of parts for mounting the air suspension Lada Priora

The principles of operation of the air suspension are based on the use of compressed air in the system, which, due to compression, is able to regulate the vehicle's ground clearance. Installing air suspension on Priora allows you to make driving more comfortable on any type of road surface.

The independent suspension in Priora is installed on the car with your own hands, and the installation process is simple. Therefore, the installation of air suspension on Priora can be carried out by all motorists, if certain tips and recommendations of specialists are followed.

To carry out the installation of the Priora suspension yourself, you need to know some of the subtleties of this operation. In addition, to carry out work on retrofitting the Priora suspension, you will need to purchase a set of parts at a car dealership. The following parts are required to perform installation work on retrofitting the suspension.

Detail	Description
air bag	The air spring is the most expensive part of all the components that make up the Priora independent air suspension. This suspension element is installed on the car instead of regular suspension elements. In the process of forcing compressed air into the pillow, the backlash of the Lada Priora changes. When airbag pressure is reduced, vehicle play is reduced. Ride height adjustment is the main function of the Priora suspension airbag.
compressor	The compressor is one of the main components of the pneumatic system, which ensures the performance of all the functions performed by the Priora suspension. The compressor installed on the car is necessary for forcing air into the airbag.
bras and straps	Independent suspension is mounted on the Priora using special mounts and steering rods. With the help of these elements, the Lada Priora air suspension is attached to the body. These parts, if you have some skills in working with metal, can be made independently, but it is better to order and make these mounts for the Priora suspension from a specialist. In this case, there will be a guarantee of high-quality manufacturing of components.
pneumatic valves	The Priora independent suspension is equipped with two pneumatic valves, which are designed to pass the pneumatic flow. One of them is designed for injection into the airbag, and the second pneumatic valve for air release.
pressure gauge	For installation in the Priora suspension system, a pressure gauge used in pneumatic systems operating at a pressure of a certain range can be used.
Start button	The start button is designed to adjust the state of the air suspension directly from the Lada Priora salon.
air supply line	the air line, which on the Priora has an independent suspension, consists of a system of tubes connecting all the airbags that form the basis of the Priora suspension.
air pressure sensor	The pressure sensor is a sensor conveniently located in the air line used to monitor the condition of the suspension directly from the passenger compartment.

The design of the standard rear suspension for Priora

On a VAZ 2170 car, the rear suspension is built from a beam, which includes two levers and a connector. All beam elements are welded with special reinforcements. Lugs are welded to the back of the arms, used to hold the shock absorbers. Also at the ends of the levers there are flanges to which the rear wheels are bolted.

Bushings are welded to the front ends of the arms, on which the suspension is mounted. Silent blocks are pressed into these bushings. Silent blocks are rubber-metal hinges. The bolts for attaching the suspension arms to the brackets pass through the silent blocks and are attached to the side members of the body.

The springs installed in the rear suspension structure rest on one side on the shock absorber cup. On the other hand, the spring stop is made on a support welded to the inner arch of the car body.

The rear suspension is equipped with hydraulic shock absorbers. The shock absorber is bolted to the suspension arm bracket. The shock absorber rod is attached to the upper spring seat with rubber grommets and a support washer. Increasingly, motorists are turning their attention to the rear suspension, which is structurally different from the rear suspension of a conventional car.

The independent rear suspension fitted to the Priora offers the driver a number of benefits. First of all, the independent rear suspension installed on the car can significantly improve the dynamic qualities of the car.

Installing a rear independent suspension on a car

An independent rear suspension is installed on the VAZ 2170 instead of the standard system installed by the manufacturer. Independent rear suspension, made on the basis of triangular levers, is most suitable for installation on Lada Priora. Independent rear suspension provides increased comfort during vehicle operation.

When operating a car with a standard rear suspension installed, the beam of the car shifts towards the nose when cornering by about 1 cm. If an independent rear suspension is installed on the car, then such a displacement of the beam under similar operating conditions is not observed. The independent rear suspension is rigidly attached to the body, without the use of silent blocks when mounting the rear suspension on the Priore, which prevents the transverse displacement of the beam.

In the design of both the Priora front suspension and the rear suspension, rubber-metal structural elements such as silent blocks are used. These structural elements consist of a rubber housing and a metal sleeve vulcanized with the base material of the silent block. In this case, the connection of the sleeve and the base is inseparable.

The silent blocks included in the design of the front and rear suspensions perform the function of damping all the torsion and bending moments that may occur during movement, thereby ensuring a stable position of the car on uneven roads and in curves.

It is the rubber-metal construction of silent blocks that is able to provide the maximum possible damping of emerging vibrations and absorption of emerging deformations. Silent blocks are structural elements that do not require additional maintenance and lubrication during operation. These structural elements cannot be repaired; after a certain period of operation, silent blocks are replaced.

Silent blocks are mounted on a car as an element of the running gear and suspension, since this structural element is one of the most reliable and economical ways to prevent various types of deformations and loads from affecting the car body that may occur during the operation of the car. Installation and replacement of silent blocks on Priore is planned in some vehicle suspension units:

• front and lower levers, by installing silent blocks, the lever is attached to the car body; in addition, by installing silent blocks, the rod was attached to the lever;
• on the stabilizer with the help of silent blocks, it is attached to the lever through the frame;
• on the attachment of the front link, called the crab;
• on the rear beam, on body accessories;
• on the rear pillars, at the top and bottom attachment points.

Replacing silent blocks on a car

The replacement of silent blocks in the nodes and parts of the chassis is carried out with a certain frequency, which depends on the intensity of operation of the vehicle and the quality of manufacture of this structural element. When performing a repair operation, such as replacing a silent block, care must be taken not to damage the new part during the pressing process.

When Priora silent blocks wear out, they must be replaced. As mentioned above, silent blocks are used in the design of the front and rear suspension of the car. The replacement of silent blocks on the Priore is carried out by pressing out the old elements to the limit of wear and installing new silent blocks in their place.

Like any part, the silent block has a specific and strictly limited resource of its service; in case of failure, it must be replaced immediately. Replacing silent blocks on Priore is carried out in several cases. The main ones are the following:

• the appearance of cracks and a decrease in the elasticity of rubber;
• breakage of the inner sleeve;
• displacement of the metal sleeve relative to the center;
• turning the silent block.

The replacement of silent blocks in a car is carried out by disassembling the part in which it is installed. After removing the part from the car, the silent block is replaced by pressing out the old part and pressing in the new part.
