Continuously Variable Transmission Provided with a Gerotor Pump

摘要

A continuously variable transmission (CVT) provided with an integrated gerotor pump that also acts as a rotation blocker is described herein. In one illustrated embodiment, the gerotor pump is used to pump lubrication and cooling fluid through a radiator and into the hollow shaft of the CVT.

主权项

1. A CVT, comprising:
a shaft rotatable within a non-rotating sleeve; a casing; a rotation blocker/pump assembly interconnecting the non-rotating sleeve and the casing, the rotation blocker/pump assembly having:
a central hub mounted to the non-rotating sleeve;an intake arm, a send arm and a return arm mounted between the casing and the central hub; anda gerotor pump associated with the central hub, the gerotor pump having an intake and an outlet; the gerotor pump having an inner rotor mounted to the shaft and an outer rotor meshed with the inner rotor; whereby a) rotation of the shaft causes rotation of the inner and outer rotors of the gerotor pump to thereby cause a pumping action between the intake and outlet of the gerotor pump and b) rotation of the non-rotating sleeve is prevented by the interconnection of the sleeve to the casing through the rotation blocker/pump assembly.
