Throttle body shaft axial play control

摘要

An electronic throttle control system with a housing (22) having a motor (40), throttle valve (60) and gear mechanism (102). The throttle valve (60) is attached to a throttle body shaft (62) which is mounted in bearings (86,88) in the housing (22). An axial spring clip (90) mechanism mounted on the throttle body shaft (62) preloads the bearings (86,88) and eliminates undesired axial and radial movement of the shaft (62) which could adversely affect the movement of the throttle valve (60) and the sensing of its position. <IMAGE>
