Abstract
Abstract An angular velocity transducer assembly for a vehicle wheel, of the type comprising an electromagnetic pick up cooperating with a relatively movable toothed wheel in which the toothed wheel is carried by the vehicle wheel and the electromagnetic pick up is carried by a mounting support on a fixed part of the vehicle to which it is attached by a tie rod in the form of a U-bolt. The mounting support is formed as a shoe having an arcuately curved surface which is adapted to bear on the axle of the vehicle either over substantially the whole of the curved surface or at various different places spaced around the curved surface.

Claim 1
Independent Claim
245 words
In an electromagnetic angular velocity transducer assembly for a vehicle wheel of the type comprising a toothed wheel and an electromagnetic pick-up device relatively moveable with respect to said toothed wheel upon rotation of said vehicle wheel upon which said toothed wheel is mounted, a mounting support for said electromagnetic pick-up comprising a curved body having a substantially semi-cylindrical surface adapted to be mounted on a cylindrical shaft, means securing said electromagnetic pick-up device adjacent the midpoint of said body intermediate the end thereof, a pair of recesses formed in said semi-cylindrical surface of said body adjacent to, but spaced inwardly from each end of said body to reduce the thickness of said body, an apertured lug integral with an extending outwardly from each end of said body, curved tie rod means adapting to extend around said shaft with the opposite ends thereof extending through said apertured lugs and threaded means for securing the ends of said tie rod to said lugs; said semi-cylindrical surface of said body between said recesses being substantially greater than the distances from said recesses to the ends of said body while the reduced thickness of said body in the vicinity of said recesses allows for the flexing of the ends of said body upon tightening of said threaded means to bring the ends of said body into contact with a shaft having a radius of curvature less than the radius of curvature of said semi-cylindrical surface of said body.
