Abstract An assembly for mounting a detector sensitive to the speed of rotation and angular position of a wheel and which allows the detector to be readily accessible for maintenance is disclosed. In addition the detector is spaced from the brakes of the wheel so that it is protected from the heating effect of the brakes which might affect its performance. The detector comprises a phonic wheel which is mounted for rotation about a hollow boss on which the wheel is rotatably mounted and through which passes the half-shaft from the differential, and a magnetic sensor which is secured to the boss. The magnetic sensor has an output lead which is guided by a groove formed by the co-operating longitudinal edges of a metal plate formed into a tube and located on the inside of the hollow boss in such a way that the half-shaft which passes therethrough also passes through the tube.
A mounting system for a detector which is sensitive to the speed and angular position of a wheel of a vehicle, the detector comprising a phonic wheel mounted for rotation with said wheel of said vehicle, a co-operating magnetic detector, and an outpuT lead from said magnetic detector, said mounting system comprising a boss, bearings by means of which said wheel of said vehicle is rotatably mounted on said boss, means mounting said detector on said boss adjacent the end of said boss outboard of said bearings, means defining a hollow bore extending through said boss, a tubular metal element within said bore, said tubular metal element being formed of a metal sheet having first and second opposite edges and being curved such that said first and second opposite edges are longitudinal of said tubular element, said first longitudinal edge being depressed to form a groove in cooperation with said second longitudinal edge, said output lead from said detector running in said groove.
