Abstract
A one-way clutch including: a wedge plate including a first radially innermost circumference with a first plurality of ramps; an inner race including a first radially outermost circumference with a second plurality of ramps and arranged to receive torque and transmit the torque to the wedge plate in a lock-mode for the one-way clutch; and a weighting element engaged with the wedge plate. The weighting element is arranged to displace, in response to rotation of the inner race, to radially contract the wedge plate.
Claims20
A one-way clutch, comprising:
- a wedge plate including a first radially innermost circumference with a first plurality of ramps;
- an inner race including a first radially outermost circumference with a second plurality of ramps and arranged to:
- receive torque;
- and,
- transmit the torque to the wedge plate in a lock-mode for the one-way clutch;
- and,
- a weighting element engaged with the wedge plate, wherein the weighting element is arranged to displace, in response to rotation of the inner race, to radially contract the wedge plate.

A one-way clutch, comprising:
- a wedge plate including:
- a first radially innermost circumference with a first plurality of ramps;
- and, first and second pluralities of slots;
- an inner race including a first radially outermost circumference with a second plurality of ramps engaged with the first plurality of ramps and arranged to:
- receive torque;
- and,
- transmit the torque to the wedge plate;
- a weighting element including:
- first and second components;
- and,
- first and second pluralities of pins:
- fixed to the first and second components, respectively;
- and,
- disposed in the first and second pluralities of slots, respectively, wherein:
- for rotation of the inner race:
- the first and second components are arranged to displace away from each other;
- and,
- to radially contract the wedge plate:
- the first component is arranged to displace to slide the first plurality of pins in the first plurality of slots;
- and,
- the second component is arranged to displace to slide the second plurality of pins in the second plurality of slots.

A one-way clutch, comprising:
- an outer race including a first radially inner circumference;
- a wedge plate disposed radially inward of the outer race and including:
- a second radially innermost circumference with a first plurality of ramps;
- a first radially outermost circumference;
- first and second ends connecting the second radially innermost circumference and the first radially outermost circumference;
- and,
- first and second pluralities of slots;
- an inner race including a second radially outer circumference with a second plurality of ramps and arranged to:
- receive torque;
- and,
- transmit the torque to the wedge plate;
- and,
- a weighting element including:
- a first component including a first plurality of pins fixed to the first component and disposed in the first plurality of slots;
- and,
- a second component including a second plurality of pins fixed to the second component and disposed in the second plurality of slots, wherein for a free-wheel mode for the one-way clutch:
- the inner race is arranged to rotate in a circumferential direction;
- the first and second components are arranged to displace away from each other;
- the first and second pluralities of pins are arranged to slide in the first and second pluralities of slots, respectively, to urge the first and second ends toward each other to radially contract the wedge plate;
- and,
- the inner race is rotatable with respect to the outer race.
