[0002] At the present stage, for the integrated disc brake rear axles used in electric tricycles and electric quadricycles, the disc brake caliper fixing cat ear plates and bearing seats are integrally cast and processed, and welded to the bridge tube.

[0003] However, the existing technology still has certain defects at present:

[0004] 1. The cat ear plates and half shaft bearing seats of the integrated disc brake rear axles are integrally castings, with relatively high manufacturing costs and accompanied by the cost loss of casting molds;

[0005] 2. The half shaft bearing is assembled into the bearing seat, and its left and right axial movements are restricted by a circlip. At present, the batch production and processing precision of the circlip groove cannot be unified, resulting in a gap between the bearing and the circlip, causing the half shaft connected to the bearing to axially jump left and right in the bearing seat, and causing the hub connected to it to axially jump left and right;

[0006] 3. The existing bridge tubes cannot be made universal for the bridge tubes of integrated disc brake rear axles and integrated drum brake rear axles;

[0007] 4. Assembly and maintenance are not convenient. The half shaft bearing uses a circlip for positioning, and the circlip is not easy to disassemble during assembly and disassembly maintenance.

[0008] Therefore, a disc brake caliper fixing chain plate is proposed. Summary of the Invention

[0011] A plurality of second fixing holes are evenly opened on the main board body, and two convex plates are symmetrically arranged on one side of the main board body far away from the opening part, and a third fixing hole is opened on the convex plate.

[0012] Preferably: A bridge tube is installed on one side of the disc brake caliper fixing chain plate, and a bearing seat and a plurality of first fixing holes are provided at one end of the bridge tube.

[0013] Preferably: The positions of the plurality of first fixing holes and the plurality of second fixing holes correspond to each other.

[0014] Preferably: A half shaft is installed inside the bridge tube, and a bearing position is provided on the outer side of the half shaft.

[0015] Preferably, a bearing is installed on the bearing position, and the bearing is matched with the bearing seat and the bearing slot.

[0016] Preferably, one end of the half shaft is connected to a differential, and the other end is connected to a disc brake.

[0017] Preferably, the third fixing hole is used to fix the disc brake caliper.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the disc brake caliper fixing chain plate can make the integrated disc brake rear axle and the integrated drum brake rear axle of the same specification used by electric tricycles and four-wheel vehicles use the same bridge tube. The processing cost is lower than the cat ear plate of the traditional integrated disc brake rear axle used by electric tricycles and four-wheel vehicles, and the size is small and the weight is light. Compared with the traditional rear axle, the installation and maintenance are more convenient, and the problem of axial runout of the half-shaft bearing in the bearing seat can be solved.
