Analysis of Special Vehicle Chassis Structure and Operation Principle

The purpose of the chassis of the special purpose vehicle is to support and install the components and assemblies of the automobile engine and the automobile to form the whole automobile. The power transmitted from the engine is transmitted to the driving wheels through the deceleration and the torque is applied to drive the vehicle forward. The chassis is equipped with steering control, brake control and vibration damping devices to ensure the normal running of the vehicle. The chassis of the vehicle consists of four parts: the transmission system, the driving system, the steering system and the braking system.

The transmission system of a car is a general term for a power transmission device between an automobile engine and a driving wheel. It can smoothly connect and transmit power or separate the power quickly and completely according to the needs; it can meet the requirements of the reverse rotation of the car and the differential rotation of the left and right drive wheels when necessary; and it must ensure the necessary traction and speed under various driving conditions. , so that the car has a good dynamic and fuel economy. Transmission systems include clutches, transmissions, directional drives, final drives, and differentials.

The vehicle driving system receives the torque transmitted from the engine through the transmission system, and generates the traction of the vehicle through the adhesion between the driving wheel and the road surface to ensure the normal driving of the vehicle. The impact and vibration caused by the uneven road surface are mitigated as much as possible to ensure the car driving. The smoothness; and with the car steering system, does not affect the steering of the car to ensure the stability and stability of the car. The driving system includes parts such as frames, axles, wheels and suspensions.

The car steering system is a mechanism for maintaining or changing the direction of the car. When the car is turning, it is necessary to ensure a coordinated angular relationship between the steering wheels. By manipulating the steering system, the driver keeps the car in a straight line or in a steering movement, or switches the two states of motion to each Other. Steering system includes: steering wheel, steering shaft, steering gear, steering straight rod, steering trapezoid, steering knuckle and other parts.

The brake system is a general term for all braking and deceleration systems installed in automobiles. Its function is to decelerate or stop the running car and to achieve reliable parking. The brake system includes front and rear brakes, control devices, energy supply devices and transmissions.
