POWER TRANSMISSION CONTROLLER

摘要

PROBLEM TO BE SOLVED: To solve a problem in a conventional power transmission wherein abrupt variation of torque and impact noise according to the operation of a stopper mechanically limiting the relative rotation of the turbine shell side to the turbine hub side of the output side rotating element of a fluid transmission device installed between the output shaft of a drive source and the input shaft of a transmission.

SOLUTION: In this power transmission controller, a torque converter 11 is installed between the output of an engine 10 and the input shaft 28 of a CVT 13. The torque converter comprises a damper 11E installed between the turbine shell 32 side and the turbine hub 34 side of the output side rotating element and allowing the relative rotation thereof and having a coiled spring 48 elastically deforming along the relative rotation thereof and a stopper 11F mechanically limiting the relative rotation exceeding a predetermined amount of the turbine shell 32 side to the turbine hub 34 side. The power transmission controller further comprises an impact relieving means for relieving impact caused by the operation of the stopper 11F.
