What are the four systems of a car chassis?
1 Answers
An automobile chassis consists of four major systems: the transmission system, the driving system, the steering system, and the braking system. Its function is to receive power from the engine, enable the vehicle to move, and ensure that the car can operate normally according to the driver's commands. The transmission system's role is to transfer the engine's power to the driving wheels. The composition of the chassis varies slightly among different vehicles; for trucks and some passenger cars, the chassis typically includes components such as the clutch, manual transmission, universal joint, and drive axle. Nowadays, automatic transmissions are increasingly used in vehicles. In such cases, the chassis comprises an automatic transmission, universal joint, drive axle, etc., effectively replacing the clutch and manual transmission. For off-road vehicles (including SUVs, or Sport Utility Vehicles), the transfer case is also part of the system. The driving system's function is to support and mount the vehicle's components and assemblies, transmit and withstand various loads from above and below the car, ensuring smooth operation. It mainly consists of the frame (or body), axles, suspension, and wheels. The steering system ensures the vehicle can follow the direction chosen by the driver. It primarily includes the steering control mechanism, steering gear, and steering linkage. Nowadays, power steering systems are widely used in automobiles. The braking system's purpose is to decelerate and stop the vehicle, ensuring reliable parking. A car's braking system generally includes two independent systems: the service brake system and the parking brake system, each comprising brakes and brake transmission mechanisms. Currently, most vehicles' service brake systems are equipped with an Anti-lock Braking System (ABS).
