The most common types of car brakes mechanisms today are wheel and transmission mechanisms.
In the first case, the brake mechanism typically effects on the wheel boss (through the detail rotating with it). In the second case, the brake mechanism affects one of transmission shaft. Then the brake moment is being transmitted to the wheels through the transmission details.
There are two kinds of service brakes depending the form of rotating detail, which stop your vehicle while driving: disc and drum brakes.
In addition, the brake mechanism can be shoe brake, belt brake and disk brake depending to the types of parts. Details that do the brake (brake shoes and brake belts) on the drum brake mechanisms can be located inside and outside the brake drum. So we will have called such brake mechanisms inside or outside mechanisms.
Disc brake mechanism can be single disk, two-disk and multi disk.
Balanced brake mechanism – is mechanism that do the braking without addition efforts to axles and wheel boss. In otherwise it is unbalanced.
Conditions for the balanced mechanism
– forces that do on the shoe brakes should be equal resultants;
– shoe brake pair of disk brake should be symmetrically located on the disk surface and on both sides of it.
Types of brake mechanisms
As we said before type of brake mechanism depends from location (wheel and transmission), form of rotating detail and type of details which do the brake. Next diagram helps you to understand the brake mechanism construction and how brake mechanism works.
