Improved connection structure between disk brake mounting board and wheel hub motor shaft

Abstract

The invention discloses an improved connection structure between a disk brake mounting board and a wheel hub motor shaft, the structure comprises a disk brake assembly, the wheel hub motor shaft and the mounting board for installing the disk brake assembly on the wheel hub motor shaft, the mounting board is provided with a mounting hole for the wheel hub motor shaft to go through, the wheel hub motor shaft is provided with a positioning device, and the mounting board is locked on the positioning device by a tightening mechanism which is arranged on the mounting hole. The structure solves the adjustment problem when the disk brake is connected with the wheel hub motor shaft and enables the installation of the disk brake to be more convenient and the brake performance to be stable and reliable.

Description

technical field [0001] The invention relates to a mechanical disc brake device, in particular to an improved structure for connecting a disc brake mounting plate and a wheel hub motor shaft applied to an electric vehicle. Background technique [0002] Service brakes have evolved from drum type, rim type to disc brake type, advancing with the times. Disc brakes have been widely installed on most motor vehicles due to their superior braking effect. Brakes, a safety and life-saving device, have no right to fail . Although the effect of disc brakes is good, the structure is complex and the installation requirements are relatively high. Disc brakes rely on the tension of the brake line to make the brake pads in the caliper rub against and clamp the disc to produce a braking effect. Therefore, the difference between the disc and the brake pads of the disc brake It is required to have a good enough parallelism, and the disc and the disc brake assembly are installed on the hub and ...

Problems solved by technology

Although the effect of disc brakes is good, the structure is complex and the installation requirements are relatively high. Disc brakes rely on the tension of the brake line to make the brake pads in the caliper rub against and clamp the disc to produce a braking effect. Therefore, the difference between the disc and the brake pads of the disc brake The distance between the disc brake assembly and the shaft requires a good enough parallelism, and the disc and the disc brake assembly are installed on the hub and its shaft, that is to say, the installation structure between the disc brake assembly and the shaft directly affects the braking effect of the disc brake.

When installing the existing disc brakes, first install the disc brake mounting plate on the rotating shaft, and then place gaskets between the mounting plate and the hub shell until the braking surface of the disc is in the middle of the two brake pads. The plate and the mounting plate are in a relatively parallel state, and the nuts are used to lock the mounting plate to prevent the axial deviation of the mounting plate. There is a manufacturing error on each end face, and the stacking of multiple gaskets will increase the cumulative error. The installation accuracy is low, and it cannot be guaranteed that the braking surface of the disc is in the middle of the two brake pads; not only that, the gasket is easily affected by external factors. Deformation makes the installation structure unstable and the installation board is easy to move

The occurrence of above-mentioned situation just makes the braking effect of disc brake drop greatly, has brought potential safety hazard to the cyclist.
