Abstract:
A thrust cam device is located at a back side of an input disc to bias the input disc toward an output disc in accordance with a torque applied thereto. The thrust cam device includes a drive cam, a back surface of the input disc, groups of cam rollers each being between respective cam surfaces of the drive cam and input disc, and a cam holder disposed between the drive cam and the input disc for rotatably holding the cam rollers. A disc spring is compressed between the input disc and the drive cam for constantly biasing the input disc toward the output disc. The input disc, the cam holder and the drive cam have respectively positioning holes which can be aligned. The positioning hole of the input disc is threaded. Upon requirement of preassembly of the thrust cam device, the input disc, the cam holder and the drive cam are turned to certain positions wherein the positioning holes are aligned, and a bolt is inserted into the aligned positioning holes and screwed into the threaded positioning hole.
