Hinge actuator for torque clutch

Abstract

The invention relates to a hinge actuator for a torque clutch, comprising at least the following components: at least one actuation finger for transmitting an actuation path to the torque clutch; a lever having a main extension, the lever being connected to the control finger; a hinge bearing having a hinge axis about which the lever is pivotable; and a crossbar in force-transmitting contact with the lever, the crossbar being movable along the main extension between a pushed-out position and a pushed-in position, and the crossbar being pivotable by means of the lever for actuation. The hinge actuator is mainly characterized in that the hinge bearing mechanism is formed by a bridge and a convex spherical projection around the hinge axis, so that only point contact is formed between the convex spherical projection and the bridge, and the convex spherical projection is attached to the bridge in a force-transmitting manner. The hinge actuator proposed herein can be used in particularly narrow construction spaces and at the same time is not structurally complex.

Description

technical field [0001] The present invention relates to a hinge actuator for a torque clutch, a torque clutch with an axis of rotation for a power train having such a hinge actuator, a power train having such a torque clutch, and a torque clutch having such a hinge actuator. The power train of a motor vehicle. Background technique [0002] A pivoting lever actuator is also known from the prior art. A pivoting lever actuator is thus already known from DE 10 2014 210 349 A1. In the pivot lever actuator, the pivot lever is pivotally supported via a mount. To this end, the seat has a surface corresponding to the ejection lever. [0003] Hinge actuators for actuating torque clutches, such as friction clutches, for drive trains, such as motor vehicle drive trains, are known from the prior art. Such a hinge actuator is shown, for example, in DE 10 2013 211 227 A1. Furthermore, such a hinge actuator is also shown, for example, in DE 10 2004 009 832 A1 (for example in FIGS. 13 t...

AI Technical Summary

Problems solved by technology

The problem generally arises that the available construction space for the hinge actuator, in particular transversely to the main extent of the lever of the hinge actuator, is extremely limited

At the same time, however, cost pressures, especially in the vehicle sector, are high not only with regard to unit costs but also with regard to installation costs
