Brake base assembly, wheel hub assembly, brake shoe, brake drum, dust cover, steering drive axle and vehicle

Abstract

The invention relates to the technical field of steering drive, and discloses a brake floor assembly, a wheel hub assembly, a brake shoe, a brake drum, a dust cover, a steering drive axle and a vehicle. A brake backplate assembly is used for a steering transaxle, the brake backplate assembly includes a brake backplane and an ABS sensor, wherein the brake backplane includes a receiving space for allowing the brake backplane to pass through the receiving space Set on the outer circumference of the hub, the brake base plate is used to be arranged on the steering knuckle assembly, the ABS sensor is arranged on the brake base plate along the radial direction, and the axis of the ABS sensor is along the radial direction direction arrangement, the radially inner end of the ABS sensor includes an electromagnetic induction head. The brake bottom plate assembly can avoid the risk of breaking the transmission signal line of the ABS sensor, and avoid the interference between the ABS ring gear and the return spring, and improve the convenience of disassembly and assembly.

Description

technical field [0001] The invention relates to the technical field of steering drive, in particular to a brake floor assembly, a wheel hub assembly, a brake shoe, a brake drum, a dust cover, a steering drive axle and a kinds of vehicles. Background technique [0002] The vehicle's ABS sensor is an important part of the vehicle's ABS system. When the vehicle is braking, the ABS sensor collects the wheel speed signal by electromagnetic induction, and sends the wheel speed signal to the controller through the wire. Control command, so that the vehicle can obtain a better braking effect. [0003] In the steering drive axle of the prior art, the ABS sensor is fixed on the brake base plate, and the axis of the ABS sensor is arranged parallel to the axis of the drive shaft, while the ABS ring gear and the wheel hub are interference fit, and the brake drum, the wheel reducer and the The wheel hub and steering knuckle assembly are connected and assembled through bolts and splines...

AI Technical Summary

Problems solved by technology

[0005] 1. During the operation of the vehicle, due to the high-speed rotation of the drive shaft and the rotation of the steering knuckle assembly during the steering process, there is a risk of breaking the transmission signal line of the ABS sensor, so that the ABS signal during the braking process The collection is abnormal, causing the vehicle to brake and deviate, causing safety hazards to the vehicle's braking;

[0006] 2. During the frequent braking process of the vehicle, the temperature of the ABS sensor is high, and the high temperature causes the ABS signal transmission line of the ABS sensor to be easily damaged, which makes the ABS signal transmission abnormal, causing the braking system to not work normally and affecting driving safety;

[0007] 3. During the assembly process of the steering drive axle, the ABS ring gear and the return spring will interfere, resulting in poor assembly process. In addition, during the maintenance of the axle, the ABS ring gear will also interfere with the return spring during the disassembly process. interference, inconvenient maintenance of the axle assembly

In addition, the weight of the ABS ring gear is relatively heavy

[0008] 4. The head of the ABS sensor is easily attached by the metal powder produced by the normal wear and tear of the friction plate of the brake shoe during the braking process, thereby weakening the strength of the magnetoelectric induction signal and affecting the normal operation of the ABS sensor
