Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to an increased impedance wear brake disc. Background Art

[0002] In the related art, when a car is driving, the brake disc and the brake caliper need to be used together to generate braking force for the vehicle. The brake disc is a very important component in the braking system. The wear resistance of the brake disc directly affects the service life. For example, the prior art discloses a wear-resistant automobile brake disc, and a friction ring is arranged on the brake disc to improve its wear resistance. However, the device needs to spend a lot of time in the process of replacing the friction ring, which leads to low efficiency of friction ring replacement. In addition, the use structure of the device such as the U-shaped block, the positioning locking rod, the locking screw and the locking clamp is too complicated, which increases the production cost of the brake disc. For this reason, an improved technology proposes a wear-resistant automobile brake disc comprising: a disc body; a friction ring, and the back side of the friction ring is arranged on the front side of the disc body. The above improved technology provides a wear-resistant automobile brake disc. By aligning the friction ring with the disc body, and then aligning the two blocks with the installation groove, using a tool to rotate the fixing screw 90 degrees, so that the two blocks enter the limit groove, the friction ring can be installed. The operation is simple and convenient, and it is very convenient to install and remove the friction ring. However, there are obvious disadvantages in the above improved technology and the aforementioned prior art. Relatively speaking, the ordinary automobile brake disc is usually replaced for at least several years or even longer, so whether the installation and removal operation of the brake disc is simple is actually not very important, resulting in the low practicality of the above improved technology. In addition, in the above two technologies and some other prior arts, the part used to increase the wear resistance effect is mostly a full disc structure. Generally speaking, the material with good wear resistance has high hardness, but high brittleness and poor impact resistance. For example, the whole piece friction ring in the above technology is clamped at the edge during braking. Under the action of the clamping force and the rotational force of the wheel axle, the edge of the friction ring is easily broken. Once broken, it not only affects the braking effect, but also may cause serious accidents. Therefore, it is necessary to make further improvements to the shortcomings of the above technology.
