A fixed conical plate that is fixed to a rotation shaft, a movable conical plate that moves in the axial direction of the rotation shaft with respect to the fixed conical plate, a slide mechanism that moves the movable conical plate, and a controller that controls the state of the slide mechanism are provided. The controller changes the groove width of a second pulley by driving a motor generator, while a first clutch is engaged, and thus moving the movable conical plate, and drives the motor generator as a generator by the rotation of the rotation shaft, by engaging a second clutch.

Continuously variable transmission and control method of continuously variable transmission

A forward clutch choke ( ) having an internal long narrow path is provided in an oil path which feeds a clutch pressure (P ) to an oil chamber ( ) of a forward clutch mechanism ( ). The choke restricts a flow of the hydraulic oil into the oil chamber at a low temperature where the viscosity of the hydraulic oil is high to thereby increase a time required for the oil chamber to be filled with the oil, which prevents the clutch mechanism ( ) from being engaged tightly in a short time to thereby prevent an instantaneous rise in the output shaft torque. Since the viscosity of the hydraulic oil is low at normal temperature and the choke functions as an orifice, the clutch mechanism is smoothly engaged tightly based on the operation of an accumulator concerned (FIG. ).

Hydraulic circuit for toroidal continuous variable transmission

In a toroidal type infinitely variable automatic transmission comprising an oil pump mounted on a transmission case, first and second toroidal transmission mechanisms disposed within the case and having input and output disks for transmitting a rotational force through a tiltable friction roller, a forward and backward change-over mechanism positioned between the transmission mechanism and the oil pump and disposed within the case, for changing over between forward and backward operations of the transmission mechanism through a planetary gear mechanism by manipulation of forward and backward clutches, and a supporting wall positioned between the forward and backward change-over mechanism and the transmission mechanism and disposed within the case, for receiving a thrust force exerted towards a transmission mechanism side by the planetary gear mechanism, an extension member is provided on a side portion of the oil pump to extend within the case towards a transmission mechanism side, and the supporting wall is mounted on the extension member at a position opposing to a carrier plate of the planetary gear mechanism.

Supporting wall structure of toroidal type infinitely variable automatic

In a toroidal type continuously variable transmission including a forward/backward switching device with a planetary gear unit, a loading cam device coaxially arranged behind the switching device to receiving a torque from the planetary gear unit, a speed change unit coaxially arranged behind the loading cam device to receive a torque from the loading cam device, and a fixed wall member arranged between the switching device and the loading cam device to rotatably support the planetary gear unit, there is provided a connecting device which directly connect a sun gear of the planetary gear unit with an input part of the loading cam device to achieve a united rotation therebetween.

Toroidal type continuously variable transmission with biasing cam

Disclosed herein is a composition for anti-reflection coating which comprises a perfluoroalkyl sulfonic acid, an organic amine, a polyvinyl pyrrolidone, a water-soluble alkylsiloxane polymer, and water. The composition is able to be an anti-reflection coating film which has a low refractive index, reduces the degree of forming insoluble layer, and does not generate fine particles and minute crystalline matters in its surface layer.
