【発明の名称】油圧式無段変速機の分配環
Document Type and Number:
Japanese Patent JPH086801
Kind Code:
B2
Abstract:
A hydraulically operated continuously variable transmission comprising a hydraulic motor (M) of the variable displacement type has a motor cylinder (8) coupled to an output shaft and including motor plungers (10) slidably disposed respectively in a number of cylinder holes (9) defined in an annular pattern surrounging the axis of rotation of the motor cylinder, and a hydraulic pump (P) coupled to an input shaft (2). The hydraulic motor and hydraulic pump are interconnected by a closed hydraulic circuit in which the flow of working oil is controlled by a distribution ring (45) which is relatively rotatably and slidably held against an end surface of the motor cylinder for successively switching the introduction of working oil into the cylinder bores and the discharge of working oil from the cylinder bores in response to rotation of the motor cylinder. The distribution ring has an asymmetrical hydraulic pressure bearing area in order to minimize forces tending to tilt the distribution ring relative to the motor cylinder end surface.
