Abstract
To provide a cam clutch easily switchable from a torque transmitting state to a freewheeling state even during torque transmission between race members. The cam clutch includes a plurality of cams set between a first race member and a second race member. The first race member and second race member are spaced away in the axial direction along the rotation axis of the first race member. The plurality of cams are disposed between the first race member and the second race member in the axial direction, and the first race member and the second race member are configured to be able to move relatively closer to and away from each other in the axial direction.
Claims8
A cam clutch comprising:
- a rotatably arranged first race member;
- a rotatably arranged second race member coaxial with the first race member;
- and a plurality of cams disposed between the first race member and the second race member,
- the first race member and the second race member being spaced away in an axial direction along a rotation axis of the first race member,
- the plurality of cams being disposed between the first race member and the second race member in the axial direction,
- the first race member and the second race member being arranged such as to be relatively movable closer to and away from each other in the axial direction,
- the cam clutch comprising a first race member unit having the first race member, and a second race member unit having the second race member,
- the first race member unit including a first lock engagement part,
- the second race member unit including a second lock engagement part capable of engaging with the first lock engagement part,
- the second race member being configured to be stopped from moving away from the first race member in the axial direction when the second lock engagement part is engaged with the first lock engagement part,
- at least one of the first lock engagement part and the second lock engagement part being provided such as to be movable in a radial direction perpendicular to the axial direction.
A cam clutch comprising:
- a rotatably arranged first race member;
- a rotatably arranged second race member coaxial with the first race member;
- and a plurality of cams disposed between the first race member and the second race member,
- the first race member and the second race member being spaced away in an axial direction along a rotation axis of the first race member,
- the plurality of cams being disposed between the first race member and the second race member in the axial direction,
- the first race member and the second race member being arranged such as to be relatively movable closer to and away from each other in the axial direction,
- the cam clutch comprising a first race member unit having the first race member, and a second race member unit having the second race member,
- the second race member unit including a control member arranged on a rear side in the axial direction opposite from a front side facing the first race member such as to be movable in the axial direction relative to the second race member, and a bias unit biasing the second race member and the control member away from each other,
- the first race member unit including a first lock engagement part,
- the second race member unit including a second lock engagement part capable of engaging with the first lock engagement part,
- the second lock engagement part being configured to engage with the first lock engagement part such as to stop the control member from moving away from the first race member in the axial direction.
