What are the systems that make up the chassis?
1 Answers
The chassis consists of four major systems: the transmission system, steering system, braking system, and running gear system. Here is a detailed introduction to the four major systems of an automobile chassis: Transmission System: The function of the transmission system is to transmit the engine's power to the driving wheels. The composition of the chassis varies slightly depending on the type of vehicle. For example, in trucks and some sedans, the chassis typically includes the clutch, manual transmission, universal drive assembly, and drive axle. However, modern sedans increasingly use automatic transmissions, where the chassis consists of the automatic transmission, universal drive assembly, and drive axle—replacing the clutch and manual transmission. For off-road vehicles (including SUVs, or sport utility vehicles), the chassis also includes a transfer case. Running Gear System: The function of the running gear system is to support and install various automotive components and assemblies, transmit and withstand loads from both inside and outside the vehicle, ensuring normal operation. It mainly consists of the frame (or body), axles, suspension, and wheels. Steering System: The function of the steering system is to ensure the vehicle can move in the direction selected by the driver. It primarily includes the steering control mechanism, steering gear, and steering linkage. Modern vehicles commonly use power steering systems. Braking System: The function of the braking system is to decelerate the vehicle, bring it to a stop, and ensure reliable parking. The automotive braking system generally includes two independent systems: the service braking system and the parking braking system. Each braking system consists of brakes and braking transmission mechanisms. Modern vehicles' service braking systems are typically equipped with an anti-lock braking system (ABS).
