Background
At the end of the 90 s, ABS systems seemed to be used only on top-grade vehicles, and nowadays ABS has become an indispensable safety feature for automobiles. Besides bearing weight and converting power, the automobile hub unit also has the function of measuring rotating speed and provides signal input for an ABS system. The accuracy of the ABS sensing probe is directly reflected on the ABS output signal. The milling distance and angle of the ABS mounting surface of the outer ring respectively affect the size and accuracy of the output signal.
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. ABS parts such as mechanical impulse wheels and sensors are required to be smaller in size, lighter in weight, better in wear resistance, lower in cost and simple and convenient to replace. 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.
In the prior art, the wheel shaft and the bearing are easy to generate matching deviation, so that the wheel shaft and the bearing slide relatively, the connection is unstable, and the effective transmission and the full utilization of the automobile power are influenced. In addition, when the automobile is emergently braked, the automobile is easy to have the condition that an axle is directly locked, so that potential safety hazards such as steering failure, sideslip and the like are caused. In addition, in recent years, with the rapid development of front-drive passenger cars, automobile hub units have changed greatly, so that a bearing unit capable of solving the above problems needs to be developed, and the assembly process is reasonable, light in weight and small in size.
