New wheel bearings NTN working principle and structure :
New Wheel Hub Bearing NTN 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 processing . Development of products high resolution signal bearing measurement 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 CNC machine tools 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 vehicle New 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 .
