FRONT WHEEL STEERING APPARATUS

摘要

In a front wheel steering apparatus including an input shaft arranged to be rotated by the driver's steering effort applied thereto, an output member operatively connected to a set of steerable front road wheels by use of a steering linkage and an interconnecting mechanism for operatively interconnecting the input shaft to the output member, an axial projection is provided on an input end of the input shaft in parallel with the rotation axis of the input shaft and at a position radially displaced a predetermined distance from the rotational axis of the input shaft, a cam follower is rotatably mounted on the axial projection, and a cam shaft is arranged in parallel with the input shaft to be applied with the steering effort for effecting rotation of the input shaft. The cam shaft has a flange portion formed with a radial cam groove for engagement with the cam follower, and the rotational axis of the cam shaft is located at a position radially displaced a smaller distance from the rotational axis of the input shaft smaller distance than the predetermined distance between the rotation axis of the input shaft and the axial projection.
