The invention "relates to an iron device for IC coupling, brake brakes, ropes

As a result of the wear and tear of the friction disks with prolonged use, the path that the actuating ring must perform changes in order to move the friction disks against one another to push so that they can transmit a torque} in other words, the normal, for not worn The actuation travel provided for friction disks is no longer sufficient to press the friction disks ^ against one another

It is known ^ between the axial support rings and the friction disks an axial force transmission ring ■ to switch on, on which a regulating disk in different Positions is adjustable · The adjustment of the regulating wheel requires subsequent checking the new position, which made the whole process time consuming

The innovation is based on the task of simplifying the setting process. This object is achieved according to the invention in that between the axial support rings. ^N and the friction disks at least one axial force transmission ring with a regulating pulley that can be set in various discrete axial positions is interposed, the respective axial position of the regulating pulley determining the effective length of the axial force transmission ring *

The adjustability of the regulating wheel in the axial direction. ^ Direction can be achieved, for example, by * that the regulating wheel is made elastic in the radial direction and axially offset against one another in different directions Engage the detent of the axial force transmission ring

. According to a preferred embodiment, the axial force transmission ring is designed as a stepped ring with steps that differ in diameter towards the associated support ring and the diameter of the regulating disk is an open single ring disk _? which can be adjusted to the different levels. .

To ensure that the regulating wheel sits firmly on the to ensure individual stages, one designed this appropriately conical with convergence in the direction of the " each next step of larger diameter and leads the inner circumferential surface of the attack disk is complementary conical.

In a 2-stage embodiment of the step ring one sees. an.dem adjoining actuating ring is expedient two staggered against each other> Axially normal * stop surfaces in front of »their radially inner with that of you

The actuating ring 5 is used _s as shown in Figures A and 2 ₉ simply to transmit a force _? the-him. is transmitted by an oil chuck 15. The sliding chuck 15 is in turn driven by an actuating sleeve 16? the actuating sleeve works together with a ball lock 14.

as long as the clutch is engaged. The actuating sleeve 16 is moved by means of a crown ring 19? the one on the Actuating sleeve 16 is supported by balls 20. One The actuating fork engages the crown ring 19.

When the friction disks are new * the regulating disk sits on step 8 in such a way that the clutch force is transmitted directly from the axial force transmission ring 5 to the step ring 6. If the clutch starts to slip, because the clutch disks are worn out, the regulating disk 7 is brought to step '9? so that the axial force transmission from the axial force transmission ring 5 to the step ring 6 takes place indirectly via the regulating disk 7. ⁷ -.
