A rack and pinion steering system including a rack slidably supported within a housing that engages in a pinion gear. A yoke assembly, including a yoke member engaging the rack, operates to guide the rack and maintain engagement of the rack and pinion during operation of the steering system. A retainer member holds a yoke plug, used in the yoke assembly, in position and also seals the yoke assembly to provide a sealed interface that protects the internal components of the steering system from water and other contaminants.

Yoke assembly for a power steering apparatus

A rack and pinion steering system including a rack slidably supported within a housing that engages in a pinion gear wherein the housing includes a cylindrical sleeve having an outer seal surface with a slight medial taper at one end thereof. A yoke assembly, which is received by the cylindrical sleeve, operates to guide the rack and maintain engagement of the rack and pinion during operation of the steering system and includes a yoke member engaging the rack. A retainer member holds a yoke plug, used in the yoke assembly, in position and has a compliant annular seal member having an inner sealing surface that has a complementary slight outward extending taper to provide a self-sealing interface with the medial taper of the outer seal surface of the cylindrical sleeve to protect the internal components of the steering system from water and other contaminants.
