摘要： A hydraulic system for a motor vehicle is provided with a pump suction enhancer for boosting the suction of operating oil into a suction port of an oil pump. The pump suction enhancer is composed of a body section for defining a small chamber, a venturi tube passage exposed to the small chamber at an inner end thereof and connected to the suction port of the oil pump, and a nozzle protruding into the small chamber to face the inner end of the venturi tube passage with a space relative to the venturi tube passage in axial alignment with the same for ejecting the operating oil returned from a flow divider into the venturi tube passage thereby to plunge the operating oil from the small chamber into the venturi tube passage. The flow divider divides the operating oil discharged from the oil pump into a return flow to the pump suction enhancer and into a supply flow which passes through a power steering device to return to an oil reservoir. In a first embodiment, the pump suction enhancer is integrally formed with the oil reservoir with the small chamber opening to a reservoir chamber defined in the oil reservoir. In a second embodiment, the pump suction enhancer is provided as a discrete component separated from the oil reservoir, oil pump and the flow divider.

摘要： A continuously variable transmission apparatus includes a toroidal continuously variable transmission, a planetary gear transmission and a clutch apparatus that connects the toroidal continuously variable transmission and the planetary gear transmission. The clutch apparatus includes: a low speed clutch a high speed clutch and a controller. The controller controls the transmission ratio of the toroidal continuously variable transmission so that rotational speeds of members connected via the clutch apparatus equals with each other, and then disengages the one of the low speed clutch and the high speed clutch after engaging the other, whereby an instance of simultaneously transmitting the power by the two clutches is set during a time period until disconnecting the other clutch after starting to transmit the power by the one clutch.

摘要： A sleeve 28 making up a gear ratio control valve 21 is driven by not only a stepping motor 29 but also a secondary actuator 47. Pressure oil is made free to be introduced into the secondary actuator 47 through a manual oil pressure switching valve 37 which is switched over by a gearshift. Then, when the gearshift is operated from a non-running state to a running state, a gear ratio of a toroidal type continuously variable transmission is corrected by a predetermined amount by driving the sleeve 28 by means of the secondary actuator 47. As a result, while improving characteristic of a vehicle when starting from rest, the vehicle can be prevented from being reduced in speed unintentionally excessively even when the gearshift is operated while running.

摘要： In a toroidal continuously variable transmission the amount of traction oil provided to contact areas between the power rollers and the input and output discs is increased as a power to be transmitted is increased. Nozzle holes formed in rockable trunnions of the transmission so that the traction oil ejected from the nozzle holes is sprayed to circumferential positions of inner surfaces of input and output discs that are in contact with peripheral surfaces of power rollers. Transmission efficiency is enhanced while maintaining endurance and reliability without supplying excessive traction oil.

摘要： In a toroidal type continuously variable transmission, first pivot shafts provided on both ends of first trunnions are supported within support holes formed in yokes secured to an inner surface of a casing. The support portions are provided with ball splines and radial needle bearings. During operation, loads acting on the first trunnions are canceled within the yokes. Axial displacements and rocking displacements of the first trunnions are effected smoothly by the ball splines and the radial needle bearings.
