    摘要： A pressure control system configured to control a selectable one-way clutch (SOWC) includes a pilot valve and a SOWC actuator. The pilot valve is configured to produce a pilot signal and includes a first valve, which is a MEMS microvalve. The pressure control system may further include a regulating valve in fluid communication with the pilot valve and configured to receive the pilot signal. The regulating valve is further configured to output a control signal. The SOWC actuator is configured to select between operating modes of the selectable one-way clutch in response to one of the pilot signal and the control signal.

    摘要： A torque transmitting system includes a case, first and second clutch plates, and a ramp member that is selectively rotatable about an axis and that defines a ramp surface. The system also includes an electric motor having a motor housing, wherein the case is rotatable relative to the housing about the axis. The motor is configured to selectively apply torque to rotate the ramp member. The system additionally includes a roller element mounted with respect to the case and contacting the ramp surface. The ramp surface is configured such that, when the ramp member is rotated about the axis, the roller element exerts a reaction force on the ramp surface that urges the ramp member to move in a first axial direction and thereby transmit the reaction force to the clutch plates. A transmission assembly including the above described torque transmitting system is also disclosed.

    摘要： A multi-speed transmission for a vehicle is provided with a selectable one-way braking clutch (SOWBC). The transmission has multiple planetary gear sets. Multiple torque-transmitting mechanisms are engagable in different combinations to establish at least one reverse speed ratio and multiple forward speed ratios between an input member and an output member. A selectable one-way braking clutch is configured to brake in one rotational direction and is selectively reversible to brake in an opposite rotational direction, and freewheels in some speed ratios.
