(1) Stamping gear ring
The inner ring or mandrel of the hub unit adopts interference fit. In the assembling process of the hub unit, the ring and inner ring or mandrel are combined together with the oil press.
(2) Install the sensor
The fit between the sensor and the outer ring of the hub unit has two forms of interference fit and nut locking. The linear wheel speed sensor is mainly the nut locking form, and the ring wheel speed sensor uses interference fit.
The distance between the permanent magnet inner surface and the tooth surface of the ring: 0.5 ± 0.1 5mm (mainly through the control of the outer diameter of the ring, the inner diameter of the sensor and the concentricity to ensure)
(3) Test voltage using homemade professional output voltage and waveform at a certain speed, for linear sensor to test whether short circuit;
Speed: 900rpm
Voltage requirement: 5.3 ~ 7.9 V
Waveform requirements: stable sine wave
