Patent JP-H01283455-A (JP)
Title: Continuously variable transmission
Inventor: AOKI HACHIRO
IPC: F16H9/00
Filed: 1988-05-06
Abstract: PURPOSE:To enable the application of a simple, compact and lightweight mechanism by giving a driving function to a pulley at the side of an auxiliary machine, constituting the entire internal area of the movable pulley of the aforesaid pulley with a pressure chamber and introducing and discharging a high pressure fluid to and from the pressure chamber via the selection of passages with an electromagnetic valve for actuating the movable pulley. CONSTITUTION:When a magnet coil 17 is not energized, the first and second main passage holes 12a and 12b are continuous to the passage 16a of a valve body 16 and a high pressure fluid is fed to a pressure chamber 10 through a route shown by an arrow, thereby keeping a movable pulley 6 in a close condition. When the coil 17 is energized, the valve body 16 slides along a shaft 4 against the force of a spring 19 and the second main passage 12b is isolated from the passage 16a and made continuous to the passage 16b, thereby interrupting the supply of the high pressure fluid. In addition, the high pressure fluid within the pressure chamber 10 flows to a sub- passage hole 13 via the second main passage hole 12b, the passage 16b and a branch passage 13a, thereby moving the movable pulley to an open side. According to the aforesaid construction, a control unit 21 is used to control the timing and frequency of the supply and interruption of a power to and from the coil 17, thereby changing the gear ratio of an auxiliary machine.

Title: Conical belt wheel type variable speed gear
Inventor: OTSUTOO DEITSUTORITSUHI
IPC: F16H61/12
Filed: 1989-05-01
Abstract: PURPOSE: To shorten the response time of each hydraulic fastening means to a great extent at the time of steep load change by installing a torque probe and pressure medium conduits leading to the hydraulic fastening means, and between the probe and conduits, installing other pressure medium conduits equipped with shutoff valves to open in the pressure feeding direction for detouring a control valve. CONSTITUTION: Between a torque probe 19 and pressure medium conduits 11 and 12 leading to hydraulic fastening means 5-7, other pressure medium conduits 23 and 24 are installed equipped with shutoff valves 21 and 22 to open in the pressure feeding direction for detouring a control valve 10. Through these bypass conduits 23 and 24, the pressure medium at the torque probe 19 can reach the fastening means 5-7 via a possibly shortest path furnished with least throat parts upon passing by the control valve 10, which should shorten the response time of the means 5-7 to a great extent. As a result, the risk of slippage of a belt 25 (tension means) is eliminated even in the case acceleration is made suddenly and/or steeply.

Title: V-belt stepless speed change gear
Inventor: NAKANO TAKATOSHI
IPC: F16H55/56
Filed: 1984-05-29
Abstract: PURPOSE:To prevent lubrication oil from leaking from a weight roller storage chamber, by providing a limiting plate for limiting the projection of a diaphragm. CONSTITUTION:When a stepless speed change gear is operated to shift a movable pulley half 18 on the drive side into a low speed rotation, the bellows section 30a of a diaphragm 30 projects out and approaches an one-way clutch 11. However, the diaphragm 30 abuts against the limiting part 33b of a limiting plate 30 and its projection is inhibited. Accordingly, the bellows part 30a of the diaphragm 30 does not make into contact with the one-way clutch 11 so that it is prevented from being worn, thereby lubrication oil is satisfactorily sealed for a long time period.
