New hub FAG bearing structure: SNR used the original magnetic encoder to develop a magnetic sensor with the highest resolution up to 40 times the original, and embedded the magnetic sensor in 2007 to develop "hub FAG bearing with high resolution rotating sensor".Because of the high resolution and high speed data processing burden, so added to the function of switching resolution.
How the new wheel hub FAG bearings work: when the vehicle at low and medium speeds, high resolution signals can be used to detect the wheel speed at 40 times the original accuracy.The motion of the standard vehicle is only 1mm, and the braking force can be controlled at the best time when controlling the vehicle.In the case of high speed where ABS control is the main purpose, the low-resolution signal is adopted to reduce the data processing burden.The product's high-resolution signal outputs pulses of phase A and phase B. By observing the output of these pulses, it is possible to detect whether the vehicle is moving forward or backward.This can be used to check whether the ramp starts to slip the car and automatic parking.The wheel speed sensor USES the sensor (fixed side) to detect the magnetic pole changes of the magnetic encoder (rotating side) that magnetizes the N pole and S pole alternately at the same interval in the circumferential direction, which can be used as the wheel rotation signal for vehicle control.By reducing the rotation signal, that is, by increasing the resolution, you can control the vehicle more precisely.
The new wheel hub FAG bearing is equipped with a rotating sensor that can be divided into two levels to switch the signal resolution, so it is safer and more convenient to detect the speed and control the ABS
