The disc drum brake system is the brake method of the front disc rear drum. In the four-wheeled car during braking, due to the inertia, the front wheel load usually accounts for 70%-80% of the total load of the car. The front wheel braking force is larger than the rear wheel, and the rear wheel plays the auxiliary braking role. In order to save costs, car manufacturers use the brake method of the front and rear drums.
The brake system of a car is divided into a disc brake and a drum brake.
The rotating element in the friction pair of the disc brake is a metal disc that works as Brake drum an end face, called a brake disc. The friction element clamps the brake disc from both sides to generate a brake.
The disc brake has fast heat dissipation, light weight, simple structure and convenient adjustment. Especially in high load, the high temperature resistance is good, the braking effect is stable, and it is not afraid of muddy water attack. In winter and bad road conditions, many disc brakes used in cars have flat brake discs, perforated brake discs and strokes. Linear brake discs, in which the scribing brake disc has better braking effect and ventilation and heat dissipation capability.
The drum brake utilizes a brake transmission mechanism to cause the brake shoe to press the brake lining against the inside of the brake drum, thereby generating a braking force, decelerating the wheel or stopping in the shortest distance as needed to ensure driving safety, and Ensure that the car is parked reliably and cannot be automatically slipped.
Drum brakes are less expensive and are easy to combine with parking (parking) brakes.
