Abstract
A cone clutch for a vehicle may include a hub, a sleeve, a clutch ring including a clutch cone, a first friction ring, an internal middle cone, a second friction ring, an external middle cone, and a third friction ring, wherein friction members are provided on only any one of two contact surfaces between the clutch cone and the first friction ring, between the first friction ring and the internal middle cone, between the internal middle cone and the second friction ring, between the second friction ring and the external middle cone, and between the external middle cone and the third friction ring.
Claims13
A cone clutch apparatus for a vehicle, the cone clutch comprising:
- a hub mounted so that movement of the hub in an axial direction of the hub and a rotation of the hub are restricted to a shaft;
- a sleeve mounted to the hub so that a rotation of the sleeve is restricted to an external side of the hub and movement of the sleeve in the axial direction is allowed;
- a clutch ring mounted so that movement of the clutch ring in the axial direction is restricted and a rotation of the clutch ring is allowed with respect to the shaft and integrally including a clutch cone protruding toward the hub and having an external diameter that is reducing;
- a first friction ring mounted between the clutch ring and the hub, mounted so that a rotation of the first friction ring is restricted with respect to the hub, and pressed toward the clutch ring along the axial direction to allow a frictional force to be applied between the first friction ring and the clutch cone;
- an internal middle cone mounted so that a rotation of the internal middle cone is restricted with respect to the clutch ring and having an internal side surface in contact with an external side surface of the first friction ring;
- a second friction ring mounted so that a rotation of the second friction ring is restricted with respect to the hub and having an internal side surface in contact with an external side surface of the internal middle cone;
- an external middle cone mounted so that a rotation of the external middle cone is restricted with respect to the clutch ring and having an internal side surface in contact with an external side surface of the second friction ring;
- and
- a third friction ring mounted so that a rotation of the third friction ring is restricted with respect to the hub and having an internal side surface in contact with an external side surface of the external middle cone when the third friction ring is pressed by the sleeve,
- wherein friction members are mounted on one of two contact surfaces between the clutch cone and the first friction ring, between the first friction ring and the internal middle cone, between the internal middle cone and the second friction ring, between the second friction ring and the external middle cone, and between the external middle cone and the third friction ring.
