Description

Technical Field

[0001] The utility model mainly relates to the technical field of sensor detection, in particular to a Hall torque sensor function detection device. Background Art

[0002] The performance parameters of the electric power steering system are directly related to the safety, reliability and comfort of automobile driving. Comprehensive online testing of the performance parameters of each component and assembly of the system is an important part of the assembly and factory inspection of the electric power steering system. The torque sensor is one of the most important components of the electric power steering system. The torque sensor signal plays a decisive role in the output power of the motor, and its output characteristics directly affect the control performance parameters of the electric power steering.

[0003] The Hall-type torque sensor is a kind of torque sensor with a wiring harness circuit board. When processing and producing such circuit boards, due to incorrect component selection, wave soldering errors, and errors in the positive and negative installation of the Hall plate, the Hall-type torque sensor cannot accurately measure the torque signal, affecting the first-time pass rate of the product. If products that do not meet national quality standards enter the market, it will cause certain safety hazards to consumers.

[0004] The traditional detection device has a motor on top, which drives the lower parts to rotate through the fixture. Due to the gap in the fixture, there will be asynchrony, resulting in inaccurate detection results and increased LFSR (Low Frequency Spatial Ripple) error of the Hall torque sensor.

[0005] Therefore, we provide a Hall torque sensor function detection device to solve the defects in the prior art. Utility Model Content
