20110152031 | SYSTEM AND METHOD FOR CONTROLLING ENDLOAD FORCE OF A VARIATOR - A system and method for controlling the endload force of a variator includes reducing a net force applied to a variator input disc of the variator. The variator includes an endload chamber, a subtraction chamber, and a valve fluidly coupled between the endload chamber and the subtraction chamber. Each of the endload chamber and the subtraction chamber applies an opposing force to the variator input disc. The valve is activateable to reduce the net force applied to the variator input disc. The valve may be activated based on the variator ratio, the position of the variator roller, and/or other parameters of the variator or operation thereof. | 06-23-2011 |
20120039554 | Housing With A Direct Flow Path For Hardware Lubrication - The present invention provides a housing that encloses a bearing. The housing includes a side wall upon which a lubricant is dispersed. The side wall has a sloped portion and a collection area is fluidly associated with the side wall. A fluid circuit is integral with the side wall such that the fluid circuit is configured to direct the lubricant into the collection area. | 02-16-2012 |
20120040794 | GEAR SCHEME FOR INFINITELY VARIABLE TRANSMISSION - A gear scheme for an infinitely variable transmission includes an input shaft, an output shaft, a variator, and a pair of planetary gearsets located beside the variator rather than in front of or behind the variator. The variator and the planetary gearsets are coupled between the input and output shafts. | 02-16-2012 |
20120122624 | Input Clutch Assembly For Infinitely Variable Transmission - The present invention provides an infinitely variable transmission for a powered vehicle which includes a power source. The transmission includes an input shaft and an output shaft, the output shaft being spaced from the input shaft. The transmission further includes a variator coupled between the input shaft and output shaft. In addition, at least two planetary gearsets are disposed adjacent to the variator and an input coupler is configured to selectively couple the variator to the power source. | 05-17-2012 |
20130220759 | Electromagnetically-Actuated Direction-Sensing Roller Clutch - A roller clutch includes an outer race, an inner race, a first engagement member situated between the outer race and the inner race, a second engagement member situated between the outer race and the inner race, and an electromagnetic mover to be energized or de-energized. The first engagement member is configured to engage the outer race and the inner race to transmit torque between the outer race and the inner race in response to the electromagnetic mover being energized and the inner race applying negative torque to the second engagement member while the outer race applies positive torque to the second engagement member. The second engagement member is configured to engage the outer race and the inner race to transmit torque between the outer race and the inner race in response to the inner race applying positive torque to the second engagement member while the outer race applies negative torque to the second engagement member. | 08-29-2013 |
20130288849 | NESTED ENDLOAD ASSEMBLY FOR A VARIATOR - A transmission includes a toroidal variator including a nested endload assembly. The nested endload assembly has two chambers configured to develop a clamping force on components of the variator. The endload assembly includes a housing, a backing plate, a piston positioned adjacent the backing plate and cooperating with the backing plate to define a first chamber for receiving pressurized fluid to act on the piston. The endload assembly also includes a load plate and an input race that cooperate to define a second chamber. The input race of the variator is acted upon by the piston when the piston is acted upon by pressurized fluid in the first chamber. The input race is also acted upon by pressurized fluid in the second chamber. | 10-31-2013 |

20140069761 | Mechanically-Actuated Direction-Sensing Roller Clutch - A roller clutch including an outer race, an inner race, a first engagement member situated between the outer race and the inner race, and a second engagement member situated between the outer race and the inner race. The first engagement member is configured to engage the outer race and the inner race to transmit torque between the outer race and the inner race only in response to the inner race turning in a positive direction and applying negative torque to the first engagement member. The second engagement member is configured to engage the outer race and the inner race to transmit torque between the outer race and the inner race in response to the inner race applying positive torque to the second engagement member while the outer race applies negative torque to the second engagement member. | 03-13-2014 |
20140262671 | TRHEE-POSITION DOG CLUTCH - A multi-positional dog clutch selectively engageable with a transmission is disclosed. The dog clutch includes a shift fork, a dog clutch carrier, a common member, and first and second dog clutch sliding members. The transmission includes first and second fixed members. The first dog clutch sliding member is configured to engage with and disengage from the first fixed member. The second dog clutch sliding member is configured to engage with and disengage from the second fixed member. The dog clutch carrier is movable to (i) a first position in which the first dog clutch sliding member is engaged with the first fixed member, (ii) a second position in which the second dog clutch sliding member is engaged with the second fixed member, and (iii) a third position in which the first dog clutch sliding member is engaged with the first fixed member and the second dog clutch sliding member is engaged with the second fixed member. | 09-18-2014 |
