The automobile hub unit in the prior art is low in assembly precision, unstable in performance and poor in using effect.

The more and more cars in modern cars are equipped with ABS, and china has required ABS to be a standard configuration for cars since 10 months of 2003. Therefore, the ABS, which has been a selling point, has been devised by manufacturers from the viewpoint of functions, and is required to have more and more strong functions and maintain the performance even at a low vehicle speed. And for ABS spare parts such as mechanical impulse wheel and sensor, the size is required to be smaller, the weight is lighter, the wear resistance is better, the cost is lower, and the replacement is simple and convenient.

Most ABS systems currently use electric sensors to detect the speed of the vehicle, which contact a gear-based wheel speed pulse, so that the gear is pressed onto the bell of the constant-speed joint in the drive wheel and is pressed onto the flange outer circle of the second-generation hub bearing unit in the driven wheel. After the gear ring is matched with the wheel speed sensor, the wheel speed sensor generates signals in the rotating process, so that the effect of measuring the running speed is achieved.
