What are the main components of an automobile chassis?
1 Answers
An automobile chassis consists of four major systems: the transmission system, the running gear system, the braking system, and the steering system. Below are the detailed descriptions of each: 1. The transmission system generally includes components such as the clutch, gearbox, universal transmission device, final drive, differential, and half-shafts. Its primary function is to transmit the power generated by the engine to the vehicle's driving wheels, creating driving force that enables the car to move at a certain speed. 2. The running gear system is composed of the vehicle's frame, axles, wheels, and suspension. It receives power from the transmission system and generates traction through the interaction between the driving wheels and the road surface, ensuring smooth vehicle operation. It also bears the total weight of the vehicle and the reaction forces from the ground, mitigates impacts from uneven road surfaces on the vehicle body, and works in conjunction with the steering system to ensure driving stability. 3. The braking system is a specialized set of devices designed to forcibly reduce the vehicle's speed. Its main functions include decelerating or stopping a moving vehicle, maintaining a stable speed when driving downhill, and keeping a stationary vehicle from moving. 4. The steering system is a series of devices used to change or maintain the vehicle's direction of travel, whether moving forward or backward. The function of the steering system is to control the vehicle's direction according to the driver's intentions. Given its critical role in driving safety, all components of the steering system are considered safety-critical parts.
