ABSTRACT:
A rack and pinion steering gear having a helical pinion engaging a rack, the rack being spring urged into engagement with the pinion and having a pair of longitudinal guide faces angularly inclined to the median longitudinal plane of the rack, one each side, the rack being supported by guide means contacting the longitudinal guide faces and arranged so that the common normals passing through the points of contact or passing through the centers of the areas of contact between the guide means and the guide faces intersect at a point displaced from the centroid of the rack section towards the pinion center-line, so as to promote rolling of the rock when poor distribution of load across the rack occurs.
