Problems solved by technology

However, as the demand for lightweight bicycles has become a trend, and the use of steel in the production of brake discs has problems of weight reduction and poor heat dissipation, so there is a need for improvement
In detail, if a lighter material is used instead of steel to make the brake disc, such as aluminum, although its weight is much lighter than steel, and it has better heat dissipation effect, but the structural strength of aluminum itself is stronger than steel Low, the brake discs produced are prone to damage and poor wear resistance

Embodiment Construction

[0018] see Figure 1 to Figure 3 , those shown in the figure are preferred embodiments selected by the present invention, which are for illustration purposes only, and are not limited by the above-described embodiments in the patent application.

[0019] The invention provides a brake disc, such as figure 1 As shown, the selected preferred embodiment has at least one through hole in a disc body 1. In this embodiment, the at least one through hole includes the empty through hole 11 located in the middle of the disc body 1 and occupying a large area. , and a plurality of through holes 12 in the shape of small round holes on the disc body 1 .

[0020] Such as figure 2 As shown, the disc body 1 includes an inner disc layer 2 and two outer disc layers 3, 4, the materials of the two outer disc layers 3, 4 are lighter than the inner disc layer 2. In this embodiment, the inner disc layer 2 is made of steel, and the two outer disc layers 3 and 4 are both made of aluminum.

Abstract

The present invention provides a brake disc. An inner disc layer and two outer disc layers are arranged in a disc body, the two outer disc layers respectively comprises second holes and relatively coat the two sides of the inner disc layer in the thickness direction, the outer diameter of the inner disc layer is larger than the two outer disc layers to form a clamping portion, the first hole of the inner disc layer correspondingly communicates with the second holes of the outer disc layers to form a through hole, there is no a portion exposing the side surface and without being coated with theouter disc layers in the through hole in the inner disc layer, a disc body is formed through composition of the inner disc layer and the outer disc layers to solve the problem that the known single-layer brake disc cannot relieve the weight or the structural strength is not enough.

Description

technical field [0001] The invention relates to a brake disc, in particular to a brake disc for bicycle brakes. Background technique [0002] It is known that the brake discs of bicycles are usually made of steel, mainly because steel has good hardness and wear resistance, so it is widely used. However, as the demand for lightweight bicycles has become a trend, and the use of steel in the manufacture of brake discs has problems of weight reduction and poor heat dissipation, so there is a need for improvement. In detail, if a lighter material is used instead of steel to make the brake disc, such as aluminum, although its weight is much lighter than steel, and it has better heat dissipation effect, but the structural strength of aluminum itself is stronger than steel Low, the brake disc produced is prone to damage and poor wear resistance. [0003] Therefore, how to solve the problem of the known brake disc is the key point of the present invention. Contents of the inventi...
