Abstract
A clutch assembly for the drive train of a motor vehicle includes a ratchet pawl carrier, which can be coupled to a first coupling element in a rotationally fixed manner, and a ratchet pawl counter element, which can be coupled to a second coupling element in a rotationally fixed manner. In a coupled state, ratchet pawls fastened to the ratchet pawl carrier engage in respective associated coupling recesses provided on the ratchet pawl counter-element. In a decoupled state, the ratchet pawls are positioned outside the coupling recesses. Each of the locking pawls is thereby loaded into a first locking pawl position by means of a respective associated spring, and can be loaded into a second locking pawl position by means of an associated actuating tappet.
Claims20
A clutch assembly for a motor vehicle drive train, comprising:
- a pawl carrier which is couplable in a rotationally fixed manner to a first coupling element which is rotatable about an axis of rotation, wherein a plurality of pawls are pivotably fastened on the pawl carrier;
- a pawl counter element which is couplable in a rotationally fixed manner to a second coupling element which is rotatable about the axis of rotation,
- wherein, in a coupled state, each of the pawls engages in the circumferential direction in a form-fitting manner into a coupling recess provided on the pawl counter element, with a result that the pawl carrier and the pawl counter element are coupled in a rotationally fixed manner at least in one direction of rotation,
- wherein, in an uncoupled state, each of the pawls are positioned outside the coupling recesses, with a result that the pawl counter element and the pawl carrier are rotationally uncoupled from one another,
- wherein each of the pawls is urged into a first pawl position via a respectively assigned spring,
- wherein each of the pawls is movable into a second pawl position counter to the urging of the respectively assigned spring via a respectively assigned actuating tappet mounted on the pawl carrier, and
- wherein the actuating tappets are mounted on the pawl carrier via a carriage and are rigidly connected to the carriage in the direction of the axis of rotation,
- the clutch assembly further comprising a sensor arrangement by which a position of the carriage along the axis of rotation is detectable.
A motor vehicle drive train comprising:
- a clutch assembly comprising:
- a pawl carrier which is couplable in a rotationally fixed manner to a first coupling element which is rotatable about an axis of rotation, wherein a plurality of pawls are pivotably fastened on the pawl carrier;
- a pawl counter element which is couplable in a rotationally fixed manner to a second coupling element which is rotatable about the axis of rotation,
- wherein, in a coupled state, each of the pawls engages in the circumferential direction in a form-fitting manner into a coupling recess provided on the pawl counter element, with a result that the pawl carrier and the pawl counter element are coupled in a rotationally fixed manner at least in one direction of rotation,
- wherein, in an uncoupled state, each of the pawls are positioned outside the coupling recesses, with a result that the pawl counter element and the pawl carrier are rotationally uncoupled from one another,
- wherein each of the pawls is urged into a first pawl position via a respectively assigned spring,
- wherein each of the pawls is movable into a second pawl position counter to the urging of the respectively assigned spring via a respectively assigned actuating tappet mounted on the pawl carrier, and
- wherein the actuating tappets are mounted on the pawl carrier via a carriage and are rigidly connected to the carriage in the direction of the axis of rotation, wherein the clutch assembly acts in a summing transmission assembly by which:
- a first electric drive motor and/or a second electric drive motor, or
- the first electric drive motor and/or an internal combustion engine, are couplable to a torque output of the motor vehicle drive train in a torque-transmitting manner.
