Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a split-type lightweight brake disc. Background Art

[0002] The braking device on a car generally includes a brake disc and a brake caliper. The brake disc includes a circular disc-shaped body with an axial hole formed in the center of the disc-shaped body. A plurality of bolt holes are formed around the axial hole so that the axial hole matches the wheel axle, and appropriate fastening bolts are selected to pass through the bolt holes and fixed to the wheel. The brake disc can be fixed to the wheel. When the vehicle needs to slow down or stop, the friction block of the brake pad contacts the disc surface of the brake disc and applies force to the brake disc. The friction between the two generates braking force, which reduces the rotation speed of the brake disc and slows down the vehicle.

[0003] The brake disc is mainly composed of a disc seat and a disc body. Most existing brake discs are integrated structures. Although they have high structural strength, the main wear part of the brake disc is located on the braking surface of the disc body. When replacing the integrated brake disc, the entire brake disc needs to be disassembled and replaced. The replacement cost is high, and the connection between the brake disc and the vehicle body needs to be disassembled. The replacement operation is difficult and inconvenient to use. In addition, traditional brake discs are mostly made of integrated cast iron. Cast iron has a high density and a large structural weight, which not only increases the difficulty of installation operation but also increases the overall weight of the vehicle after installation and improves the fuel consumption of the vehicle.
