The ABS control used to prevent slipping during braking can detect the turning speed of the wheel, so the device is mounted near the front and rear wheel bearings of the car. Since the ABS detector and the magnetic pulse ring are assembled on the drive wheel side of the vehicle, respectively, they are exposed to the outside, and the sensing portion is easily immersed in foreign matter such as muddy water. On the other hand, in the assembly of the vehicle body, the process of attaching the detector to the joint and the process of preventing the iron scrap from adhering to the magnetic pulse ring have become problems.
This time, the "hub bearing with integrated seal and integrated ABS detector" developed by JTEKT has prevented the use of a filling seal at the ABS detector and the magnetic pulse ring inside the bearing. Immersion of muddy water or the like to the sensing portion. At the same time, processes such as "prevention of adhesion of magnetic pulse ring iron filings" and "gap adjustment" necessary for assembling the vehicle can be omitted.
The new product will be available for sale in 2010, and the sales target of JTEKT is to achieve sales of 7 billion yen in 2013.
