Product analysis:
The car wheel bearing device is installed in the wheel hub component of the car; it is a function of the improved wheel bearing; the wheel bearing has been developed from the early two single-row tapered bearings to the double row tapered roller bearing and the double row angular touch ball bearing; Bearing-centered wheel bearing unit.
The first generation of hub bearings consists of two single-row tapered bearings; the primary function is to support the rotation of the wheel; the requirements of the device are adjusted to ensure that the bearing has a reasonable clearance,
The second-generation wheel bearing is a hub bearing unit consisting of a double-row tapered roller bearing or a double-row angular touch ball bearing; a special high-performance grease is added inside the bearing; the device is a unit type; the clearance of the bearing unit is not required to be adjusted,
The third-generation car wheel bearing unit; the primary layout of the product is two double-row angular touch ball bearings with flange layout; one flange is connected with the car hub and the other flange is connected with the suspension; the inner hole is coupled with the drive shaft; The bearing unit is equipped with synchronous speed measuring plate and high-function sensor; it is the signal collecting unit of the car ABS system; it is a mechatronic product with high technical content, and the fourth-generation car wheel bearing unit is an inner sleeve or jacket and transmission between them. The shaft is a whole part; the layout is more compact than the third generation; the third and fourth generation wheel bearing products are mainly used for cars with ABS system; it is the development trend of medium and high-class cars and advanced commercial wheel hub bearings.
