Embodiment Construction

[0018] figure 1 The illustrated first embodiment of the clutch actuating mechanism according to the invention is arranged, for example, on a transmission input shaft, not shown, from which the figure 1 The left side extends to the coupling element 1 on the transmission side of the clutch actuating mechanism. clutch operating mechanism figure 1 The right side of the engine is facing the engine. The coupling part 1 on the transmission side is adapted on its inner peripheral surface to the transmission input shaft, for example by means of corresponding spline teeth etc., so that in the assembled state the coupling part is connected to the transmission in a non-positive or form-fitting manner in the peripheral direction input shaft, but can still move axially. Furthermore, the clutch actuating mechanism includes the engine-side coupling part 2 . The coupling part 2 is supported axially via a rotationally symmetrical shoulder on a corresponding shoulder 21 at the end of the tra...

Abstract

The invention relates to a clutch actuation unit for motor-driven vehicles, the clutch of which can be actuated both arbitrarily and depending on a torque / rotational speed differential occurring at the clutch. The clutch actuation unit comprises a transmission-side and an engine-side dog. Ramps or counter-ramps and contact surfaces in mutual engagement are formed on the dogs, transferring a drivetorque via the contact surfaces when the dogs are rotated in a rotary direction, and converting the rotary motion into an axial motion of a dog by means of the ramps or counter-ramps when the dogs arerotated in opposite directions, said motion causing the clutch to open. The clutch actuation unit is characterized in that the engine-side dog (2, 5), including the outer sleeve thereof, is coaxiallyand rotatably disposed relative to a transmission input shaft. Further, the engine-side dog (2, 5), including the outer sleeve thereof, is displaceable in the axial direction relative to the transmission input shaft, wherein the displaceability thereof in the direction toward the transmission housing is limited by a stop (3). The transmission-side dog (1) is interlocked or force-locked coaxiallyand circumferentially, but axially displaceable on the transmission input shaft having outer teeth, wherein the displaceability thereof in the direction toward the transmission housing is limited by the engine-side dog (2) and / or by a stop.

Description

technical field [0001] The invention relates to a clutch actuation mechanism for a motor vehicle, the clutch of which can be actuated not only at will, but also on the basis of torque / speed differences occurring at the clutch. In a vehicle such as a delivery truck, car, tricycle, quadricycle or motorcycle, an engine such as an internal combustion engine and / or an electric motor and / or a hydraulic motor etc. generates a drive torque which is used by means of a suitable drive train to make the vehicle Forward. The drive train usually includes a clutch, such as a friction clutch, arranged after the engine. In the direction of the power flow path, the transmission is connected to the clutch, and the output torque of the transmission is transmitted to one or more drive wheels, possibly with a differential or a chain drive or a cardan drive in between. Background technique [0002] When the driving power of the vehicle thus configured is reduced (freewheeling), the engine genera...
