AI Technical Summary
In the existing technology, feeler gauges are prone to elastic deformation when measuring the axial distance between the wheel speed sensor and the sensing disk, which affects the measurement accuracy and makes it difficult to achieve high-precision distance adjustment.
By employing a main support and adjustment device, combined with a vernier or digital display vernier caliper, and setting up a first counting mechanism, the sensor can be accurately translated and the distance displayed along the axis of the sensing disk, ensuring precise adjustment of the axial distance between the sensor and the sensing disk.
It enables accurate adjustment of the axial distance between the sensor and the sensing disk, improving the accuracy and consistency of measurement results and avoiding errors caused by feeler gauges.
