Abstract:
1. A clutch device of a motor vehicle drive train transmission, comprising: a first clutch element; a second clutch element; wherein the first clutch element and the second clutch element are supported to rotate about a common rotational axis, and wherein the first clutch element and the second clutch element are coupled to one another in an engaged state in a form-locking manner by a sliding sleeve, wherein the sliding sleeve is attached in a rotationally-fixed, and axially-displaceable manner to the first clutch element; wherein the sliding sleeve comprises a peripheral surface having a first step, the first step having a first step flank extending with a first step course on the peripheral surface of the sliding sleeve, wherein the first step course exhibits at least one axial directional component in the direction of the axis of rotation; and a placement agent capable of sliding radially back and forth between a first engaging placement agent position and a first disengaging placement agent position, and is otherwise stationary, wherein the placement agent rests against the first step flank during a procedure for disengaging the first and second clutch elements in the first disengaging placement agent position such that the sliding sleeve moves axially away from the second clutch element to a disengaged sleeve position with a rotation of the first clutch element until the first and second clutch elements are mechanically disengaged from one another in a disengaged state, wherein the sliding sleeve is supported by an axially-acting spring such that a spring force of the spring retains the sliding sleeve in an engaged sleeve position or acts to slide the sleeve into the engaged sleeve position, and when the sliding sleeve is in the engaged sleeve position, the first clutch element is mechanically coupled to the second clutch element.
