Brake bottom plate assembly, 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 bottom plate assembly, a hub assembly, a brake shoe, a brake drum, a dust cover, a steering drive axle and a vehicle. The brake bottom plate assembly is used for a steering drive axle, the brake bottom plate assembly comprises a brake bottom plate and an ABS sensor, the brake bottom plate comprises a containing space for allowing the brake bottom plate to be sleeved on the periphery of a hub through the containing space, and the brake bottom plate is used for being arranged on a steering knuckle assembly. The ABS sensor is arranged on the brake bottom plate in the radial direction, the axis of the ABS sensor is arranged in the radial direction, and the radial inner end of the ABS sensor comprises an electromagnetic induction head. According to the brake bottom plate assembly, the risk of breakage of a transmission signal line of the ABS sensor can be avoided, interference between an ABS gear ring and a return spring is avoided, and the disassembly and assembly convenience is improved.

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
