What is an integrated car frame, its purpose
Content
The vehicle platform usually resembles a horizontal "ladder" of metal beams. The connections of the elements are usually welded. Or using bolts and rivets.
The own weight of any machine and external loads are taken by a powerful metal frame. An integrated car frame is a combination of a body with side members and cross members. The design has the necessary properties - rigidity, strength and efficiency.
What is an integrated frame
The power frame is the basis of the car, on which all other components and parts are located. The design provides rigidity sufficient to take the load in motion.
Ways of fastening the body to the power frame of the car:
- separately on rubber cushions;
- a single whole;
- rigid connection with the frame.
The design of the carrier platform has several subspecies for different brands of machines. The integrated frame of the car as a body, connected to the spars and cross members by welding, takes the load on the car completely. Longitudinal spars connect parts of the car frame, and transverse beams create the necessary rigidity. Such a one-piece integrated frame in a car is more common on crossovers and SUVs.
Integrated frame features
Benefits of a base platform with a mixed body mount:
- ease of installation on the conveyor using automatic welding;
- uniform load on the frame elements;
- small weight of the platform;
- increased rigidity, no torsional deformation during sharp maneuvers.
Thanks to this, the integrated frame on the vehicle can withstand heavy loads when driving on uneven roads.

The power frame of the car acts as a support for components and assemblies. Provides secure fastening and structural rigidity. The integrated frame of the vehicle is bolted or welded to the body. Provides a high level of passenger safety, well dampens blows from any direction.
The main elements of the integrated auto frame are longitudinal channels connected by transverse beams of different widths.
On the surface of the frame, places are allocated for the engine, transmission and main components. The body is usually welded to the side rails of the car frame, which increases the overall rigidity of the structure. For reliable operation of the power frame of a car, maintenance is required - periodic revision of welds and anti-corrosion protection.
Integrated frame design
The vehicle platform usually resembles a horizontal "ladder" of metal beams. The connections of the elements are usually welded. Or using bolts and rivets.
In the design of cars with an integrated frame, there are no special subframes for attaching heavy units. Part of the units and parts of the machine is located below the surface of the spars to reduce the center of gravity.
List of cons of an integrated car frame:
- strength is lower than that of a separate platform;
- possible corrosion and microcracks in welds;
- complexity of repair work.
More often, the design of the power frame resembles a ladder made of metal beams. But sometimes the frame spars are connected at an angle in the form of the letter X or K. In trucks, a spinal structure is used, and in sports cars, a spatial power frame.

Vehicles with an integrated frame
New models of off-road vehicles are more often made with a monocoque body.
List of cars with integrated frame:
- Nissan Terrano is an inexpensive car with good design and high cross-country ability. The power of the gasoline engine is 114 l / s., The volume is 1,6 liters.
- SsangYong Rexton is a crossover with good value for money. Interior trim is made of wood-like plastic and leather. Engine power 2,0 l - 225 l / s.
- The American SUV Jeep Wrangler has an aesthetic interior design. Diesel engine 2,8 l develops a power of 200 l / s. A car with a reliable suspension and transmission easily overcomes off-road.
- Jeep Cherokee is a powerful car with a good reputation. It is produced in two versions - a 3,6 liter gasoline engine with 272 l / s, 2,0 l - with 170 l / s. The suspension is soft, well dampens shock and vibration from road irregularities.
- Nissan Patrol is a massive premium car with good dynamics. The spacious interior is trimmed with leather and high-quality plastic. Engine capacity - 5,6 liters, developed power - 405 l / s.
There is a demand on the market for comfortable and economical models at the expense of cross-country ability and reliability. This means that the integrated frame on the car will be installed on most new crossovers and SUVs.
