Description

Vehicle and steering knuckle assembly thereof

Technical Field

The utility model relates to the technical field of vehicles, and particularly provides a vehicle and a steering knuckle assembly thereof.

Background

The steering knuckle and the hub bearing are one of important parts of an automobile running system, and the steering knuckle is used for transmitting and bearing the front load of the automobile and driving a front wheel to rotate around a main pin so as to steer the automobile; the hub bearing is mainly used for bearing weight and providing accurate guidance for the rotation of the hub. For modern vehicles, a vehicle dynamic control system (VDC), a vehicle Electronic Stability Program (ESP), an Antilock Brake System (ABS), a control system of an automatic transmission, etc. require wheel speed information, and therefore, a wheel speed sensor for acquiring wheel speed information is also indispensable. In the prior art, the knuckle, the hub bearing and the wheel speed sensor are typically integrated as an assembly.

Common wheel speed sensors include hall wheel speed sensors and magneto-electric wheel speed sensors. Taking a magnetoelectric wheel speed sensor as an example, the principle of realizing wheel speed detection is as follows: the steering knuckle is provided with a sensing head of a wheel speed sensor, the sensing head comprises a permanent magnet core, a polar shaft, an induction coil and the like, a hub bearing is provided with a magnetic ring, and the magnetic ring is of a gear ring structure made of ferromagnetic materials. When the wheel rotates, the magnetic ring rotates synchronously with the wheel, the gap between the iron core and the magnetic ring in the sensing head changes along with the alternate change of the tooth top and the tooth bottom of the magnetic ring, so that the magnetic flux in the induction coil around the iron core changes, and the induced electromotive force which changes alternately is generated, and the frequency of the induced electromotive force change corresponds to the tooth number of the magnetic ring. The measured induced electromotive force is processed by a processor, and then the information such as the rotating speed, the acceleration and the like of the wheel can be calculated.

However, the wheel speed sensor in the prior art is easily exposed in an open environment, and thus, external magnetic foreign matters enter and adhere to the magnetic ring, so that the wheel speed detection accuracy is affected, and the driving control of the vehicle is not facilitated.
