摘要

The yoke has a face of concave contour, at back of a steering rack. The face of concave contour is provided with ribs that are separated by grooves to form reduced contact surface between yoke and steering rack. Partitions are formed transverse to the grooves and in a plane perpendicular to the direction of displacement of the steering rack. The partitions and the grooves delimit multiple cavities of grease supply.
