Patent number: 11040718Abstract: A launch control method is provided for a vehicle having an accelerator, a brake and a continuously variable transmission (CVT). The method comprises determining: (i) a braking torque set by a vehicle operator by pressing a brake pedal of the vehicle; and (ii) a holding torque required to hold the vehicle in a stationary position. The method also determines that the operator has released the brake pedal. The brake is released whilst engaging a launch clutch of the CVT, wherein the launch clutch is engaged by increasing a clutch engagement pressure at a first pressure ramp rate, such that the sum of the braking torque and a clutch torque of the clutch remains equal to the holding torque. An acceleration torque requested by the operator via the accelerator is determined. The clutch engagement pressure is increased at a second pressure ramp rate when it is determined that the braking torque is substantially zero, such that the clutch torque is increased by the acceleration torque.Type: GrantFiled: September 17, 2018Date of Patent: June 22, 2021Assignee: Perkins Engines Company LimitedInventors: Michael Beyer, Michael Cronin, Steven Spencer, Matthew Mauritzson, Kevin Stutzman

Patent number: 11022210Abstract: A planet wheel shaft includes a bearing portion for acting as a slide-bearing in cooperation with a planet wheel of a planetary gear. On at least one axial region of the bearing portion, a cross-sectional shape deviates from a circular shape so that the bearing portion is thicker in a first direction than in a second direction perpendicular to the first direction. The deviation from the circular shape widens a wedge-shaped gap that is between the bearing portion and the planet wheel when there is load in the first direction. This facilitates oil supply to an area where hydrodynamic oil pressure is formed for carrying load in the first direction because the widening the wedge-shaped gap compensates for narrowing the gap due to ovalization of the planet wheel caused by load in the second direction.Type: GrantFiled: December 16, 2019Date of Patent: June 1, 2021Assignee: MOVENTAS GEARS OYInventor: Tuomo Kontinen
