Description

Automotive Disc Floating Caliper

technical field

The utility model relates to the technical field of brake structures, in particular to an automobile disc-type floating caliper.

Background technique

With the development of the economy, the number of automobiles in my country has gradually increased. In today's tight oil resources, energy issues have become the focus of the country's increasing attention. Energy saving and environmental protection are particularly important for the design and development of automobiles.

The brake is an important part of the transmission system of the car. When the car brakes, the two friction plates clamp the brake disc to brake the car. However, when the brake is released, the friction lining cannot completely and quickly break away from the brake disc, and in the following driving, the friction lining still produces a relatively large dragging resistance to the brake disc. This causes useless dragging energy loss, reduces the effective utilization rate of vehicle energy, and also increases the wear and tear of friction linings and brake discs, reducing the life of the brake.

Although there are some existing disc floating brakes with a friction plate reset device, they only reset the friction plate on one side, and the non-reset friction plate on the other side still produces dragging loss.

In addition, the installation accuracy of the brake plays an important role in the braking effect and the service life of the brake. Since the caliper of the disc floating brake is installed on the bracket, and the ordinary bracket is installed with two holes, three points can be determined. Therefore, the installation accuracy of the bracket is often not guaranteed, which will cause the movement direction of the piston rod to be non-perpendicular to the brake disc, thereby affecting the braking effect and service life of the brake.
