The car body frame is the basis of all parts installation. The car has chassis, and there are so many spare parts in the chassis, such as engine, gearbox, wheels, suspension, brake, etc. Most of the cars adopt the load-bearing body. The girder of the load-bearing body is integrated with the car shell, which makes the body lighter and more comfortable. In terms of chassis, there are two front and rear sub-frames, so the front suspension of engine transmission of horizontal engine front drive vehicle is fixed on the front sub-frame, and the rear sub-frame is fixed to the rear suspension. If it is a rear drive vehicle with longitudinal engine, only the engine and suspension system are fixed on the front sub-frame, and there are rear suspension and differential on the rear sub-frame. There are many driving forms of automobile, such as front front front drive, front four-wheel drive, front rear drive, middle rear drive, middle four-wheel drive, rear four-wheel drive, rear rear rear drive, etc. Most family cars use front drive, so the front drive is generally transverse engine. The front and rear drive are usually longitudinal engines. Some front four-wheel drive vehicles use a transverse engine, while some front four-wheel drive vehicles use a longitudinal engine. The layout of the engine is related to the driving mode. The front-end drive vehicle will have under-steer in fast cornering, while the front rear drive will have over-steer in fast cornering. Automobile suspension is divided into independent suspension and non independent suspension. Torsion beam is commonly used in non independent suspension, while McPherson strut type, double wishbone type and multi-link type are commonly used in independent suspension.
