Abstract
In a gear-jumping-proof positive-locking clutch for connecting a vehicle transmission shaft to a transmission component mounted coaxially and rotationally with it, the positive-locking clutch includes an axially displaceable sliding sleeve on which at least one locking roller element may be supported which is displaceable in a radial locking recess with axial displacement of the sliding sleeve due to a radial force component. In a gear-jumping-proof positive-locking clutch which does not cause any transmission noise when disengaged, the positive-locking clutch is free of synchromesh bodies and the locking roller element is axially displaceable.
Claims21
A gear-jumping-proof positive-locking clutch configured to connect a motor-vehicle transmission shaft to a transmission component mounted coaxially and rotatably with respect to the transmission shaft, comprising:
- at least one axially displaceable locking roller element;
- and
- an axially displaceable sliding sleeve configured to support the at least one locking roller element;
- wherein the at least one locking roller element is displaceable into a radial locking recess located in at least one axial end of a transmission shaft shoulder in accordance with a radial force component with axial displacement of the sliding sleeve, the locking roller element located in the locking recess at a time of establishment of the connection between the vehicle transmission shaft and the transmission component, the positive-locking clutch being free of synchromesh bodies.
A gear-jumping-proof positive-locking clutch configured to connect a motor-vehicle transmission shaft to a transmission component mounted coaxially and rotatably with respect to the transmission shaft, comprising:
- at least one axially displaceable locking roller element;
- and
- an axially displaceable sliding sleeve configured to support the at least one locking roller element;
- wherein the at least one locking roller element is displaceable into a radial locking recess in an axial end of a synchromesh body in accordance with a radial force component with axial displacement of the sliding sleeve, the locking roller element located in the locking recess at a time of establishment of the connection between the vehicle transmission shaft and the transmission component;
- wherein the locking roller element is configured to roll on the synchromesh body connected in a rotationally fixed manner to the vehicle transmission shaft by a shaft-hub connection.
A gear-jumping-proof positive-locking clutch configured to connect a motor-vehicle transmission shaft to a transmission component mounted coaxially and rotatably with respect to the transmission shaft, comprising:
- at least one axially displaceable locking roller element;
- and
- an axially displaceable sliding sleeve configured to support the at least one locking roller element;
- wherein the at least one locking roller element is displaceable into a radial locking recess in accordance with a radial force component with axial displacement of the sliding sleeve, the locking roller element located in the locking recess at a time of establishment of the connection between the vehicle transmission shaft and the transmission component, the positive-locking clutch being free of synchromesh bodies;
- wherein a roller element support is rotationally fixed and axially displaceable with respect to the vehicle transmission shaft, the locking roller element guidable inside the roller element support;
- wherein the roller element support includes an axially aligned support gearing constantly engaging a shaft gearing arranged in a rotationally fixed manner with respect to the vehicle transmission shaft, the support gearing in a disengaged state rotatable with respect to the transmission component and, in an axially displaced and clutched state of the positive-locking clutch, engaged in a gearing of the transmission component;
- and
- wherein the support gearing comprises a radial locking recess in at least one axial end.
