| 474029000 | Including actuator interconnecting plural pulleys on spaced shafts for simultaneous adjustment | 7 |
| 20080214340 | Belt Type Continuously Variable Transmission, Control Device for Belt Type Continuously Variable Transmission, and Vehicle - A belt type continuously variable transmission for a vehicle such as a motorcycle includes a primary sheave and a secondary sheave each having a pair of flanges axially movable relative to each other. A belt is wound around the sheaves. An actuator controlled by a control device moves the flanges. The control device includes a determination section for determining whether the actual gear ratio of the belt type continuously variable transmission has become a predetermined gear ratio for TOP or LOW, and a first correction section for correcting an operation amount of the actuator based on the determination made by the determination section. Control accuracy in a region where the gear ratio is TOP or LOW is thereby improved. | 09-04-2008 |
| 20100248875 | CONTINUOUSLY VARIABLE TRANSMISSION AND CONTROL METHOD THEREOF - A transmission controller permits a 2-1 shift, in which a gear position of a subtransmission mechanism is changed from a second speed to a first speed, when an accelerator pedal has been depressed to or above a predetermined opening. The gear position of the subtransmission mechanism is changed from the second speed to the first speed when an actual through speed ratio passes a mode switch line from a High side to a Low side while the 2-1 shift is permitted in the subtransmission mechanism. | 09-30-2010 |
| 20130260929 | CONTROL DEVICE AND CONTROL METHOD FOR CONTINUOUSLY VARIABLE TRANSMISSION - The present invention is provided with a hydraulic control circuit including a hydraulic pump driven by a driving power source in order to supply an oil pressure to a hydraulic circuit, a hydraulic auxiliary unit for supplying an accumulated oil pressure to the hydraulic circuit, and a control valve for supplying at least one of oil pressures of the hydraulic pump and the hydraulic auxiliary unit to pulleys, and a control unit for executing a coast stop control to stop the driving power source while traveling and controlling, when an increase of torque inputted to the continuously variable transmission is detected or predicted during the coast stop control, the control valve so as to supply an oil pressure of the hydraulic auxiliary unit to the pulleys. | 10-03-2013 |
| 20160200357 | CONTINUOUSLY VARIABLE TRANSMISSION SYSTEM | 07-14-2016 |
| 474030000 | For axial adjustment of each member on each pulley | 3 |
| 20090239690 | IN-SERIES TWO CHAIN CONTINUOUSLY VARIABLE TRANSMISSION - A continuously variable transmission has an input pulley assembly connected to a first transfer pulley assembly with a first chain and a second transfer pulley assembly connected to an output pulley assembly with a second chain. The first transfer pulley assembly and the second transfer pulley assembly shaft a common shuttle disk that moves axially on a countershaft that carries the first and second transfer pulleys. The input pulley assembly and the output pulley assembly are generally axially aligned and a bearing carrier is positioned between the pulleys. A high pressure fluid supply system reduces or eliminates axial loading on the shafts of the transmission. | 09-24-2009 |
| 20090270209 | Gear assembly and constinuously variable transmission comprising gear assembly - The present invention concerns a gear assembly, suitable for a continuously variable transmission, comprising two gear tooth devices ( | 10-29-2009 |
| 20140357435 | SYSTEM AND METHOD FOR MINIMAL DRAINDOWN IN CVT - A hydraulic control system for a transmission is provided. The hydraulic control system provides a latching system to retain CVT clutch pressure and/or pulley pressure for one or more CVT torque transmitting mechanisms and/or CVT pulleys in a CVT transmission. Components of the hydraulic control system of the present disclosure may include blow off valves, such as ball check-valves, on the exhaust of the pulley control valves and the exhaust of the CVT clutch control valve(s), and a one-way valve, such as a supply ball check-valve, disposed adjacent to each of the fluid supply inlets of the pulley control valves and the fluid supply inlet of the CVT clutch control valve(s). | 12-04-2014 |
