Coupling device

摘要

A coupling device including at least one torque transmitting device, which can be engaged and/or disengaged in the axial direction by a lever element and which is frictionally engaged in the engaged state, and including at least one wear compensation device, which has at least one rotatable ramp ring that can be clamped by the lever element at least temporarily and which has at least one rotatably mounted spindle drive with a spindle shaft, the spindle drive acting on the ramp ring. The wear compensation device has at least two continuously variable free running units which act in different rotational directions, a first free running unit being designed to rotate the spindle shaft when a wear state of the torque transmitting device is sensed and a second free running unit being designed to prevent a reverse rotation of the spindle shaft.

1. A coupling device comprising
at least one torque transmitting device, which is engagable or disengagable in an axial direction (A) by a lever element and is frictionally engaged in the engaged state, at least one wear compensation device, which has at least one rotatable ramp ring that is clamped by the lever element at least temporarily and which has at least one rotationally mounted spindle drive with a spindle shaft, and said spindle drive acting on the ramp ring, and at least first and second continuously variable free running units arranged on the spindle shaft, which act in different rotational directions, with the first free running unit being designed to rotate the spindle shaft when a wear state of the torque transmitting device is sensed and the second free running unit being designed to prevent a reverse rotation of the spindle shaft.
