Description

Drive axle wheel edge assembly with ABS wheel speed sensor

Technical Field

The utility model relates to a drive axle wheel limit assembly, especially a take drive axle wheel limit assembly of the fast sensor of ABS wheel.

Background

An ABS anti-lock brake system is an automobile safety control system with the functions of skid resistance, locking prevention and the like. The ABS wheel speed sensor is one of important components of an ABS anti-lock braking system, is used for measuring the rotating speed of a wheel in real time and transmitting the rotating speed to the ABS electronic control unit through electronic signals, and the ABS electronic control unit analyzes and calculates the electronic signals to control the slip rate of the wheel, so that the safety and reliability of the automobile during braking are improved. The ABS fixed bolster is the support that is used for the fast sensor of fixed mounting ABS wheel, and at present in the drum-type rear axle, the assembly position of ABS fixed bolster has following two kinds:

the ABS fixing support is assembled at the head of a brake bottom plate bolt, a threaded hole is drilled at the head of the brake bottom plate bolt, then the ABS fixing support is fixed at the position of the brake bottom plate bolt through a bolt and an elastic pad, and for products with a far distance from a gear ring position, the ABS fixing support needs to be designed to be very high, so that the ABS fixing support occupies a large space on the one hand, and materials and cost are increased on the other hand. When the assembling method is used in mass production, the bolt assembling position of the ABS fixing support and the separation of the bolts of the ABS fixing support need to be noticed when the bolts of the brake bottom plate are assembled, so that the assembling process is increased, and the assembling efficiency is influenced.

The other method is to weld the ABS fixed bracket at the shaft tube, the method is only limited to a brake with large specification, the seam allowance of the brake bottom plate of the brake with small specification can not pass through the ABS fixed bracket, the structure has great limitation on use, is not suitable for all products, and has lower universality; and through the ABS fixed bolster that goes up in the welding, its position degree and installation error are great, can not guarantee the straightness that hangs down of probe behind the fast sensor of ABS wheel well, cause certain influence to output signal.
