Chassis refers to the combination of four parts on the car, which is the transmission system, the driving system, the steering system and the braking system. It supports and installs the car engine and its components and assemblies to form the overall shape of the car, bear the power of the engine, and ensure normal driving. The engine is called the heart of the car, and the chassis is called the pile foundation of the car, which is a very important core system. It can be seen that the status of the chassis in the whole vehicle, a mature chassis system or architecture is the core competitiveness of a product series and even a company. The chassis is an important part of the car, and it is also the most important factor affecting the driving quality of the car. All the forces when the car is running, whether it is the driving force transmitted by the engine to the wheels, or the force of the ground reaction and the car, are ultimately undertaken by the chassis system.
The car driving system includes: frame, axle, suspension and wheels and other parts. Car driving system The role of the car steering system is to change or maintain the direction in which the car is traveling or reversing. A mechanism used to maintain or change the direction a car is traveling. When the car is steered, it is also necessary to ensure that there is a coordinated angular relationship between the steering wheels. By manipulating the steering system, the driver keeps the car in a straight line or turning motion, or converts the two motion states into each other. The steering system includes: steering control mechanism, steering gear, steering transmission mechanism and other parts. The function of the car steering system is to control the driving direction of the car according to the driver’s wishes. The steering system of the car is very important to the driving safety of the car. Therefore, the parts of the car steering system are called security parts. The braking system includes: brakes and braking transmissions. Anti-lock braking devices are also installed in the braking system of modern automobiles.The function of the car braking system is to make the moving car decelerate or even stop according to the driver’s request; make the parked car park stably under various road conditions (including on slopes); Car speed remains stable.
Generally speaking, chassis engineering includes the design configuration of front and rear suspension, steering system, braking system and wheels. Vehicle performance directly related to these systems are braking, handling and smoothness. The suspension components of the chassis themselves must be strong enough, and whether their design is in place directly affects the force of the frame body, and the chassis design is also related to durability. An excellent chassis can provide a guarantee for the stability, NVH and vehicle durability of a car. The key to the chassis design is to meet the various indicators of vehicle performance. The basic performance that a car should have can be summarized as power, economy, braking, handling, smoothness, safety and durability.
