Abstract
A clutch assembly includes a main rotational axis, a first clutch partner and a second clutch partner, a plurality of control members and a slider sleeve. The plurality of control members are arranged to control a coupling device, and the coupling device arranged to couple the first clutch partner and the second clutch partner. The slider sleeve is coaxially displaceable with respect to the first clutch partner and the second clutch partner to actuate the plurality of control members. The plurality of control members is arranged on a radial inside of the slider sleeve and displaceable in a radial direction relative to the main rotational axis.
Claims18
A clutch assembly, comprising:
- a first clutch partner and a second clutch partner, the clutch partners defining a main rotational axis,
- a slider sleeve arranged so as to be displaceable coaxially with respect to the two clutch partners, and
- a plurality of control members for controlling a coupling device for coupling the clutch partners, the control members being actuated by the slider sleeve, wherein:
- the control members are arranged radially on the inside with respect to the slider sleeve and are arranged so as to be displaceable in the radial direction to the main rotational axis;
- the first clutch partner has an external toothing and the second clutch partner has a locking toothing;
- the slider sleeve is in rotationally fixed engagement with the external toothing via an internal toothing;
- and
- the internal toothing can also be brought into rotationally fixed engagement with the locking toothing when the slider sleeve is displaced in order to couple the two clutch partners to one another in a rotationally fixed manner.
A clutch assembly comprising:
- a main rotational axis;
- a first clutch partner and a second clutch partner;
- a plurality of control members arranged to control a coupling device, the coupling device arranged to couple the first clutch partner and the second clutch partner;
- and
- a slider sleeve, coaxially displaceable with respect to the first clutch partner and the second clutch partner to actuate the plurality of control members, wherein:
- the plurality of control members is arranged on a radial inside of the slider sleeve and displaceable in a radial direction relative to the main rotational axis, wherein:
- the first clutch partner comprises an external toothing;
- the second clutch partner comprises a locking toothing;
- the slider sleeve comprises an internal toothing in rotationally fixed engagement with the external toothing;
- and
- when the slider sleeve is displaced, the internal toothing is arranged to be brought into rotationally fixed engagement with the locking toothing to couple the first clutch partner to the second clutch partner in a rotationally fixed manner.
A clutch assembly comprising:
- a main rotational axis;
- a first freewheel clutch partner;
- a second freewheel clutch partner comprising a plurality of ramp-like locking contours;
- a switchable freewheel device arranged to couple the first freewheel clutch partner and the second freewheel clutch partner, the switchable freewheel device comprising a plurality of spring-loaded locking bodies arranged on the first freewheel clutch partner, each of the plurality of spring-loaded locking bodies comprising a locking section and a deactivation section;
- a plurality of control members arranged on a radial inside of a slider sleeve and displaceable in a radial direction relative to the main rotational axis to control the switchable freewheel device;
- and
- the slider sleeve, coaxially displaceable with respect to the first freewheel clutch partner and the second freewheel clutch partner to:
- bring the plurality of control members into a connected position to connect the switchable freewheel device so that the switchable freewheel device can assume a locked state or a freewheeling state depending on a rotational direction or a rotational speed of the first freewheel clutch partner and the second freewheel clutch partner;
- and
- bring the plurality of control members into a disconnected position to disconnect the switchable freewheel device so that the first freewheel clutch partner and the second freewheel clutch partner are rotationally decoupled from one another, wherein:
- when the plurality of control members is in the connected position:
- each of the plurality of spring-loaded locking bodies is pivoted in a first pivot direction about a pivot axis running parallel to the main rotational axis into an active position;
- the switchable freewheel device is engaged;
- and,
- when the first freewheel clutch partner is rotated relative to the second freewheel clutch partner in a first rotational direction, each locking section is radially deflected to interlock with a one of the plurality of ramp-like locking contours;
- and
- when the plurality of control members is in the disconnected position:
- the plurality of control members press on respective deactivation sections to pivot the respective locking bodies in a second pivot direction, opposite the first pivot direction, into a passive position in which the respective locking sections are disengaged from the ramp-like locking contours;
- and
- the switchable freewheel device is disengaged.
