Abstract
In an electrical speed sensor for generating an electrical signal proportional to the rotational speed of a vehicle wheel, a first shaft is rotatably mounted and is adapted to be operatively interconnected with an output shaft of the vehicle transmission. The first shaft carries a rotor of magnetic material which is cooperable with a stationary rotor of magnetic material to provide an output signal indicative of the rotational speed. A second shaft is rotatably mounted at a fixed angle relative to the first shaft in operative driven engagement therewith. The rotatable core of a speedometer cable is coupled to one end of the second shaft for rotation therewith to operate the vehicle speedometer.
