What is a Drum Braking System?
Drum brake is through the brake pads, friction brake drum, the principle of braking, the cheapest. , The general car with a multi-disc type, is through the friction bare brake disc, brake, the heat dissipation is good, the heat recession is small, the car is used at present,
That is, both the brake discs and the more traditional drum brakes, this advantage is better braking effect, the disadvantage is more complex manufacturing, and the higher cost, as far as I know only a few models are used discs drum brake: Huatai Santa Fe
The drum brakes use the brake mechanism to press the brake shoe against the inside of the brake drum to produce the braking force, to slow down the wheel or to stop in the shortest possible distance to ensure safety Protect the car parked reliable and can not automatically slip. Drum brakes are less costly and easy to combine with parking (parking) brakes.
Drum-type brake system, that is, before the drum after the drum brake method. In the four-wheel car in the braking process, due to the role of inertia, the front wheel load is usually 70% of the total load -80% of the car, the front wheel brake force than the rear wheel, the rear wheel auxiliary brake, Car manufacturers in order to save costs, the use of drum before the drum before the way. The car's braking system is divided into disc brakes and drum brakes. The rotating element in the disc brake friction pair is a metal disc that operates on the end face and is called a brake disc. The friction element engages the brake disc from both sides to produce a brake. Disc brakes fast heat, light weight, simple structure, easy to adjust. Especially when the high load resistance to high temperature performance, the braking effect is stable, and not afraid of mud water invasion, in the winter and bad traffic conditions, many cars used disc brakes have flat brake discs, perforated brake discs and Line brake disc, in which the brake wheel brake effect and ventilation and cooling capacity are better.
