New Wheel Hub Bearing works: when the car in case of low and medium-speed, high-resolution signal can be 40 times the original wheel speed detection accuracy. Can be detected by standard vehicle only 1mm movement, control of the vehicle when the best time to be able to control the braking force. In the ABS control for the main purpose of the high speeds, the use of low-resolution signals to reduce the burden of data Four-Row Cylindrical Roller Bearing processing. Development of products high resolution signal output A-phase and B-phase two kinds of pulses, these pulses output by observing the situation, be able to detect the vehicle is moving forward or backward. This can be used to detect whether the start ramp and automatic slip car parking and so on. Wheel speed sensor using a sensor (fixed side) detected at the same intervals on the circumferential direction are alternately magnetized N pole and the S pole magnetic encoder (rotation side) of the magnetic pole changes, as the wheel rotation signal for vehicle control. Reduced rotation signal, which is to improve the resolution, will be able to more finely control the vehicleNew Wheel Hub Bearing NTN structure: NTN and SNR using the original magnetic encoder developed a resolution of up to 40 times the original magnetic sensor, and in 2007 developed the magnetic sensors embedded in the "rotation sensor with high resolution hub bearing" . Since high resolution and high speed data processing burden, thus switching the resolution added functionality.
