摘要： A pair of pulleys for a belt-and-pulley type continuously variable transmission wherein the pulleys are connected by a transmission belt such that the belt is partially in contact with contact surfaces of the pulleys. At least one of the pair of pulleys has a contact surface which has a plurality of raised and recessed portions that are spaced apart from each other at irregular angular intervals in a circumferential direction of the pulley.

摘要： In a toroidal type continuously variable transmission having an input disk, an output disk and power rollers sandwiched and frictionally engaged between the input and output disks so as to transmit rotational power therebetween at a transmission ratio variable according to the inclination of the power rollers relative to the input and output disks, a stationary shaft is provided as supported by a housing, and the input and output disks are rotatably supported by the stationary shaft via individual radial bearing means and individual axial bearing means. The stationary shaft has an axial bore and transverse orifices, and the bearings are lubricated by lubrication oil supplied through the axial bore and the transverse orifices.

摘要： An apparatus for controlling a hydraulically operated continuously variable transmission for a motor vehicle, which has an input member, an output member and a power transmitting member connecting the input and output members, and whose power transmitting capacity changes with a pressure of engagement of the power transmitting member with the input and output members. The apparatus includes a torque detector for detecting an input torque of the transmission, a hydraulic actuator adapted to receive a controlled pressure for controlling the pressure of engagement of the power transmitting member, and a device for changing the area of the pressure-receiving surface of the hydraulic actuator to thereby change the pressure of engagement of the power transmitting member, with the detected input torque of the transmission.

摘要： A variator assembly comprises a variator of the toroidal-race rolling-traction type using double-acting pistons to control the rollers and differential end load pressure to load the variator, and control means operative to vary the differential end load pressure in sympathy with changes in the net pressure exerted by the roller-control pistons so as to maintain the traction coefficient at the roller disc interface consistently below the limit at which traction would be lost.
