Abstract
A rack and pinion steering gear of the kind in which a helical pinion engages a rack mounted in bearings, the rack being supported opposite the pinion by a spring loaded half round support journal, the spring acting to hold the pinion in contact with the teeth of the rack which are formed in such a manner as to provide in about the center of the rack a 'ramp' in which there are tooth gaps of varying height providing a variation of slack free mesh center distance between the pinion and the rack, the maximum mesh center distance occurring in the mid travel portion of the rack and lesser mesh center distances occurring in positions of travel of the rack either side of the travel position of the present invention being characterized by the fact that the tooth gaps concerned are formed in such a manner as to form a ramp extending across the rack at an angle substantially the same as the angle made by the pinion axis with the rack axis whereby the possibility of an uneven distribution of the load between the teeth of the pinion and the teeth of the rack is reduced.
