A clutch assembly is provided. The clutch assembly includes a basket member, an input member and an actuator that is disposed within the basket member. A hub member, having a hub spline and an inclined portion is disposed adjacent to the actuator. A cam member, having a cam spline and cam lobes is rotatably disposed on the input member. A shaft member, having a shaft spline and plurality of slots is rotatably disposed on the input member. The hub spline is engaged with the cam spline in a disengaged position of the actuator. The clutch assembly further includes a plurality of balls received within the corresponding slots of the shaft member. While moving towards an engaged position of the actuator, the cam spline aligns with the shaft spline thereby the hub spline engages with the shaft spline in the engaged position of the actuator. |

1. A clutch assembly comprising:
an input member extending along a rotation axis; a basket member rotatable about the rotation axis and spaced apart from the input member; a connecting member connecting the input member and the basket member; a plurality of first clutch plates slidably disposed on the basket member; an actuator disposed adjacent to the connecting member in a disengaged position thereof, the actuator being movable along the rotation axis between the disengaged position and an engaged position; a hub member disposed adjacent to the actuator, the hub member being configured with the actuator to move along the rotation axis to the engaged position, wherein the hub member includes a hub spline and an inclined portion; a spring member configured to bias the hub member and the actuator in the disengaged position; a plurality of second clutch plates slidably disposed on the hub member, wherein each of the plurality of second clutch plates are disengaged from the first clutch plates when the actuator is in the disengaged position, and wherein each of the plurality of second clutch plates are engaged with the adjoining first clutch plates when the actuator is moved to the engaged position; a cam member rotatably disposed on the input member, the cam member including a cam spline and a plurality of cam lobes, wherein the cam spline and the hub spline are engaged in the disengaged position of the actuator; a shaft member extending along the rotation axis, the shaft member including a shaft spline and a plurality of slots, the shaft member is rotatably disposed on the input member, the shaft spline being misaligned with the cam spline in the disengaged position of the actuator, wherein the shaft member is rotatable about the rotation axis relative to the cam member when the shaft spline and the cam spline are misaligned; and a plurality of balls at least partly received within the corresponding slots of the shaft member; wherein in the disengaged position of the actuator, the balls are retained at least partly within the corresponding slot by the inclined portion of the hub member against a centrifugal force, wherein the hub member is configured to move the plurality of balls to engage with the corresponding cam lobes due to movement along the rotation axis, wherein the plurality of balls rotate the cam member in order to align the cam spline with the shaft spline, and wherein the hub member is slidable relative to the cam member and the shaft member when the cam spline is aligned with the shaft spline. |
