An excessive torque releasing type clutch apparatus comprises an outer ring, an inner ring arranged radially inside and coaxially with the outer ring and rotatably relative to the outer ring, a torque transmitting portion capable of transmitting torque between the outer ring and the inner ring, and a restricting mechanism for restricting excessive torque from being input from an input torque transmitting member to a driving ring of the outer ring and the inner ring and restricting excessive inverse torque that is input to a driven ring of the outer ring and the inner ring from being input to the input torque transmitting member. Treatment steps for securing strength of constituent members of the clutch apparatus in manufacturing be simplified or omitted.

Clutch apparatus

A clutch apparatus comprises a first race, a second race arranged coaxial with and rotatable relative to the first race, and an engagement mechanism provided between the first race and the second race for engagement of the first race and said second race. The engagement mechanism comprising a first clutch allowing rotation of the first race in only one direction, and a second clutch arranged axially adjacent to the first clutch, the second clutch comprising a rotary member that is provided on the second race in a rotatable and axially immovable manner and a movable member that is movable in the axial direction, and a cam mechanism disposed between the rotary member and the movable member, and the movable member being engaged with the first race by being moved in the axial direction by the cam mechanism.

A one way clutch comprises an outer race including a radially outer first annular part to which rotation is input from outside and a radially inner second annular part capable of rotating when receiving rotation from the first annular part, an inner race provided radially inside the outer race and rotatable relative to the outer race, a plurality of torque transmission members provided between the outer race and the inner race to transmit torque between the outer race and the inner race, and a coupling mechanism that couples the first annular part and the second annular part together to make them integrally rotatable when the speed of rotation input from outside is lower than a specific speed and decouples them when the speed of rotation exceeds the specific speed.

One way clutch

A one-way clutch apparatus of torque input-switching type in which torque capacity can be secured without increasing an axial dimension. The one-way clutch apparatus of drive input-switching type, includes a plurality of first torque transmitting members interposed between a shaftand an intermediate ringat circumferential predetermined intervals, and provided for transmitting torque between the shaftand the intermediate ring, and a plurality of second torque transmitting members interposed between the intermediate ringand an outer ringat circumferential predetermined intervals, and provided for transmitting torque between the intermediate ringand the outer ring, in which either the torque input into the shaftor the torque input into the outer ringis transmitted to the intermediate ring, in which the first torque transmitting member is a spragand the second torque transmitting member is a roller

One-way clutch apparatus

A one-way clutch allows unlocking torque input to a movable retainer to be made low, thereby enabling downsizing of an external apparatus that inputs unlocking torque to the movable retainer. The one-way clutch includes an inner ring, an outer ring, first rollers used to transmit torque between the inner ring and the outer ring provided in an annular space between the inner ring and the outer ring, and fixed retaining portions of a fixed retainer and a movable retaining portions of a movable retainer that are arranged alternately. The one-way clutch also includes second rollers provided between the movable retaining portions and the first rollers adapted to transmit unlocking torque from the movable retaining portions to the first rollers and the inner ring as the movable retaining portions move in a clockwise direction.

One-way clutch

A two-way clutch includes an outer race having a cam section in an inner periphery, an inner race that is separated in an inside diameter direction with respect to the outer race, and is disposed concentrically to be relatively rotatable, a torque transmission member that is disposed between the outer race and the inner race, and transmits torque, a cage that is capable of engaging with the torque transmission member and is movable in a circumferential direction, a drag strip that is supported by the cage, and a switching mechanism that can cause the two-way clutch to take at least a state locked in two directions by causing the drag strip to slide onto the inner race.

Two-way clutch

A liquid pressure generating apparatus including a pump, and two one-way clutches arranged coaxially with the pump drive shaft in a line in the axial direction on the side of a first axial direction. The pump case includes a projecting portion projecting from the corresponding pump case. Inner races of the respective two one-way clutches are integrated with each other and form a common inner race. Outer races of the respective two one-way clutches are formed independently from each other and are driven respectively by pump driving members different from each other, and directions of restricted relative rotation with respect to the common inner race are identical to each other. The common inner race includes a coupling portion to be coupled to the pump driving shaft on the side of the first axial direction with respect to the projecting portion.

Liquid pressure generating apparatus and driving apparatus

A liquid pressure generating apparatus including a pump; and two one-way clutches arranged coaxially with the pump's drive shaft. Inner races of the respective two one-way clutches are integrated with each other to form a common inner race. Outer races of the respective two one-way clutches are formed independently from each other and are driven respectively by pump driving members different from each other. The common inner race includes a coupling portion coupled to the pump drive shaft and extending in the radial direction and a cylindrical body portion extending from the coupling portion in a second axial direction opposite from the first axial direction on the radially outside the pump drive shaft. The body portion includes a depression indented radially outward on an inner peripheral surface thereof. A lubricant supply portion for the depression is provided radially inside the depression.

A differentially controllable two-way clutch including an outer wheel with a cam portion on an inner circumference, an inner wheel arranged apart from the outer wheel and toward an inner diameter of the two-way clutch as well as rotatably and concentrically with respect to the outer wheel, a torque transmission member located between the outer wheel and the inner wheel to transmit torque, a cage configured to hold the torque transmission member and to be slidable in a circumferential direction and which is differentially controlled, and a spring supported by the cage and configured to be capable of biasing the torque transmission member so that the torque transmission member engages with a cam surface.

Differentially controllable two-way clutch

The present invention provides a sprag type one-way clutch of disengaging type comprising an outer race having a substantially annular inner peripheral track surface, an inner race spaced apart from the outer race in a radial direction and disposed coaxially with and rotatable relative to the outer race and having a substantially annular outer peripheral track surface, a plurality of sprags disposed between the outer race and the inner race to transmit torque between the inner and outer track surfaces, and a ribbon spring for applying rising moment to the sprags, and wherein an outer diameter side cam surface of the sprag is provided with a mechanism for preventing fluctuation of the sprag during a predetermined number of idle revolutions of the outer race.

One-way clutch of sprag type

A one-way clutch comprising an inner race and an outer race radially spaced apart from each other and concentrically disposed for rotation relative to each other, and a spray disposed between the inner race and the outer race for transmitting torque is characterized in that the cam surface of the sprag which contacts with the outer peripheral surface of the inner race is formed with a plurality of axially extending grooves.
