Description

made in the form of a clamp and placed between it and the bulkhead of the sleeve case, on which the friction disks are mounted with axial movement, and the feedback mechanism is rigidly connected to the sleeve and installed rotatably in the drive sprocket and in the housing partition shaft, in which the said axial and radial holes are made, moreover, in the form of radial holes of the shaft arranged in the shaft with the possibility of radial movement of the sliders and kinematically connected with axial with relative axial movement. the shaft of a finger rigidly fixed on the flange, as well as installed rotatably on the shaft between the housing partition and the flywheel drive star with shaped grooves on the inner surface fixed axially, and balls contacting the surfaces of the flywheel shaped grooves and with sliders .

FIG. 1 shows a friction clutch, general view; in fig. 2 shows section A-A in FIG. 1. The friction clutch contains a leading coupling half, made in the form of a drive sprocket 1, to which the cylindrical body 2 is rigidly fixed with an internal partition 3. On the inside of the right compartment of the body 2 there are axial grooves 4 for installing the leading friction disks 5, which are mounted with the ability to interact with the driven clutch discs 3 W discs 6 driven half coupling. The latter are mounted on the slots 7 of the sleeve 8, which is rigidly connected to the shaft 9 of the feedback mechanism. The feedback mechanism also includes a finger 10 mounted for axial movement in the groove 11 of the shaft 9, a pressure 12 a flywheel 13 mounted for rotation on the shaft 9 and having .shaped recesses 14 on the inner surface in contact with the balls 15 , interacting with 1m with sliders 16, installed in radial holes (not indicated) of shaft 9, which are slidable with axial hole 17 9. The clutch packs of friction disks 5 and b are clamped by pos. . By means of the spring 18, the nut 19 and the clamp 12, the shaft 9 is mounted with OWNS1 necks in two bearings 2b rolling. The axial movement of the flywheel 13 is limited by the sleeve 21. In the axial bore 17 of the shaft 9, an axially displaceable movement is provided. 22. The free space between the sliders 16 and the piston 22 is filled with a viscous fluid, such as hydroplastic 23. In order to eliminate slipping between the extreme friction disk 5 or 6 and the clamp 12 during normal operation of the coupling, since the coefficient of friction between them is less than the corresponding coefficient between the friction overlays with the drive disks 5 and sending out the disks 6, the pressing of said disks is carried out by a friction lining

24 rigidly connected to the clamp

 12.

The operation of the coupling is as follows.

The rotational movement is transmitted from asterisk 1 to

5 case 2, disks 5 and b, shaft 9, flywheel 13 and on the working body (not indicated). When overloaded (stopping shaft 9), the flywheel 13 due to the moment of inertia continues to rotate relative to 9, In this case, the balls

15 move with the sliders

16k axis of the shaft 9, while moving the piston 22 and the pin 10 to the right with the clamp 12 and thus disconnecting

5 packages of friction disks 5 and b, which at the same time freely rotate one relative to others.

The invention, due to the simple design, allows to increase the sensitivity and accuracy of the coupling operation, the smoothness of its inclusion.
