The invention discloses a Hall effect efficiency detection device and method for a wheel speed sensor. The Hall effect efficiency detection device comprises a first motor, a hub gear ring, a wheel speed sensor mounting bracket, a driving assembly and a detection controller, an output shaft of the first motor is connected with the hub gear ring, and the first motor is used for driving the hub gear ring to rotate at a constant speed; the wheel speed sensor mounting bracket is used for fixing a wheel speed sensor to be detected, and the wheel speed sensor and the hub gear ring are oppositely arranged; the driving assembly is connected with the wheel speed sensor mounting bracket, and the driving assembly is used for driving the wheel speed sensor mounting bracket to move in the horizontal direction, so that the distance between the hub gear ring and the wheel speed sensor is changed; the detection controller is electrically connected with the first motor, the driving assembly and the wheel speed sensor. The Hall effect efficiency detection of the wheel speed sensor is realized through the simple device, the detection cost is reduced, and the potential quality hazard caused by actual measurement of loading is avoided.
Description
technical field [0001] The invention relates to the technical field of chip detection, in particular to a Hall effect detection device and method for a wheel speed sensor. Background technique [0002] In recent years, with the rapid development and progress of mechanical and electronic technology, the competition in the field of mechanical and electronic processing has become increasingly fierce. The requirements for product quality are getting higher and higher; the vehicle wheel speed sensor is an important part of the chassis braking system of the vehicle, and the main engine manufacturers have put forward higher and higher requirements for the technical indicators of the vehicle wheel speed sensor. Therefore, the quality control of the vehicle wheel speed sensor assembly in the manufacturing process is becoming more and more strict. [0003] At present, the current popular vehicle wheel speed sensor assemblies are all magnetic sensor chips based on the Hall effect. It ...
