Abstract
A system and method for an actuation assembly for a transmission. The actuation assembly, in one example, includes a first cam device that is idly coupled to a support shaft and a second cam device idly coupled to the support shaft. The actuation assembly further includes a first one-way clutch which is coupled to the first cam device and an idler gear that is rotationally coupled to an actuator and a second one-way clutch that is coupled to the second cam device and the idler gear that is rotationally coupled to the actuator.
Claims20
An actuation assembly in a transmission, comprising:
- a first cam device idly coupled to a support shaft;
- a second cam device idly coupled to the support shaft;
- a first one-way clutch coupled to the first cam device and an idler gear that is rotationally coupled to an actuator;
- and
- a second one-way clutch coupled to the second cam device and the idler gear;
- wherein the first and second one-way clutches drive the first and second cam devices in opposing rotational directions.
A method for operation of an actuation assembly in a transmission, comprising:
- rotating an idler gear in a first direction to drive rotation of a first cam device;
- and
- rotating the idler gear in a second direction, which is opposite the first direction, to drive rotation of a second cam device;
- wherein the actuation assembly comprises:
- the first cam device idly coupled to a support shaft;
- the second cam device idly coupled to the support shaft;
- a first one-way clutch coupled to the first cam device and the idler gear that is rotationally coupled to an actuator;
- and
- a second one-way clutch coupled to the second cam device and the idler gear.
An actuation assembly in a transmission, comprising:
- a shifting cam device idly coupled to a support shaft;
- a parking cam device idly coupled to the support shaft;
- a first one-way clutch coupled to the shifting cam device and an idler gear that is rotationally coupled to an actuator;
- and
- a second one-way clutch coupled to the parking cam device and the idler gear;
- wherein the first and second one-way clutches drive the shifting cam device and the parking cam device in opposing rotational directions.
