Wheel-speed sensors for motor vehicle mounted in the spreader holes of a differential carrier housing

摘要

The invention relates a speed-sensing system to monitor the speed of individual wheels of a vehicle. A vehicle axle including a carrier housing and differential case assembly rotatably mounted within said carrier housing includes speed-sensing equipment associated with the carrier. The carrier housing has axle tubes extending therefrom in which axle shafts for the vehicle are disposed. The axle shafts are drivingly coupled to the case assembly and each includes a signal generator thereon. A sensing device is mounted in spreader holes in the carrier housing and positioned relative to the signal generator to monitor the rotary motion of the shaft and generate a signal which can be used by an onboard computer to control the speed of the axle shaft for the individual wheel of the vehicle. There is further described a method of assembling an axle assembly for a vehicle having a wheel speed sensor.
