What are the four basic components of a braking system?
1 Answers
The braking system mainly consists of four parts: the energy supply device, control device, transmission device, and brake. The primary functions of the braking system are to decelerate or even stop a moving vehicle, maintain a stable speed for a vehicle going downhill, and keep a stationary vehicle from moving. It is a series of specialized devices designed to forcibly reduce the speed of a vehicle. The basic structure of a general braking system is as follows: 1. Wheel brake: mainly composed of the rotating part, fixed part, and adjustment mechanism. The rotating part is the brake drum; the fixed part includes the brake shoe and brake backing plate; the adjustment mechanism consists of an eccentric support pin and an adjustment cam used to adjust the shoe-drum clearance. 2. Hydraulic brake transmission mechanism: mainly composed of the brake pedal, push rod, master cylinder, wheel cylinder, and pipelines. 3. Pneumatic brake transmission mechanism: mainly composed of the brake pedal, push rod, brake master valve, air dryer, four-circuit protection valve, brake chamber, and pipelines.
