What is the difference between floating disk and fixed disk?

1. Fixed type mainly means that the brake caliper is fixed, while floating type means that the brake caliper is floating;

2. Fixed type braking is controlled by The piston in the caliper extends and clamps the brake pad against the brake disc, generating friction and braking force.

Brake

Brake refers to the component that generates braking torque and is used to hinder the movement or movement tendency of the vehicle. At present, friction brakes are mostly used in automobiles, which use the friction between the working surfaces of fixed components and rotating components to generate braking torque.

According to different installation positions, brakes can be divided into wheel brakes and central brakes. Brakes whose rotating elements are fixed on the wheels or axles are called wheel brakes; brakes whose rotating elements are fixed on the drive shaft of the transmission system are called central brakes. Wheel brakes are generally used for driving braking, and some are also used for emergency braking and parking braking; central brakes are generally only used for parking braking and retarding braking.

According to different rotating components, friction brakes can be divided into two categories: drum type and disc type. The rotating element in the drum brake friction pair is a brake drum, with its cylindrical surface as the working surface; the rotating element in the disc brake friction pair is a disc-shaped brake disc, with its cylindrical surface as the working surface. The end face is the working surface.

Disc brakes are divided into caliper disc brakes and full disc brakes according to the different structural forms of their fixed components. The fixed element and rotating element of the friction pair of the full disc brake are both disc-shaped and are called fixed disc and rotating disc respectively. All working surfaces of the brake disc can be in contact with the friction plate at the same time, and its structural principle is similar to that of a friction clutch.
