Abstract

The invention relates to mechanical engineering, in particular, to switching off friction clutches, and can be used in mechanisms of machines subjected to frequent overloads, and where a complete break of the kinematic chain is necessary, in particular in transmissions of automobiles and tractors. The purpose of the invention is to improve performance and reliability by stabilizing the pressing force, as well as increasing stability in operation. Intermediate elements (E) 6 are made with inclined surfaces 11 and mounted on the rods x 9 between the pressure springs 5 and the casing 4. The pushers (T) 8 contact the ends with the surfaces 11. The stops 10 are made on T 8 and are in contact with the inclined sections 12 rods 9. The friction pairs between the O 6 and the pushers 8, as well as between the portions 12 and the stops 10, are non-braking. The axial force component from the T 8 side of each E 6 is greater than the nominal axial component of the corresponding pressure spring 5. When the drive 1, the driven 3 and the pressure 2 disks wear, the latter moves. T 8 is compressed through the E 6 spring 5 to the nominal force. 2 hp ff, 2 ill.

Description

The invention relates to mechanical engineering, in particular, to switching off friction clutches, and can be used in the mechanisms of machines subjected to frequent overloads, and where a complete breakdown of the kinematic chain, in particular g transmission, of automobiles and tractors is necessary.

The purpose of the invention is to increase the operational quality and reliability by tabilizing the pressure force, as well as the magnitude of the stability of the work.

Fig. 1 shows a friction clutch, generally: in Fig. 2 - unit for stabilizing the pressure force.

The friction clutch contains a master 1, a pressure 2 and a slave 3 disks located between them, a casing 4, a pressure device made in the form of pressure springs 5, a squeezing device, intermediate elements 6. spring-loaded via springs 7, pushers 8, guide rods 9, and also stops 10. The pressure springs 5 are installed so that one of their ends interacts with the pressure disk 2, and the second with the casing 4 Intermediate elements 6 are made with inclined working surfaces 11 and are mounted on guide rods x 9 between the pressure with the springs 5 and the casing 4 with the inclined working surfaces 11 to the last the guide rods 9 are made with sections 12 inclined to one end and mounted with the second end on the pressure disk 2. The pushers 8 are located with contact end surfaces with inclined working surfaces 11 intermediate elements 6. The stops 10 are made on the pusher 8 and are arranged with contact with the inclined sections 12 of the guide rods 9 Friction pairs between the intermediate elements 6 and the pushers 8. as well as between the inclined sections 12 and The stops 10 are non-self-braking. The axial force on the side of the pushers 8 of each intermediate element 6 is greater than the nominal axial component of the corresponding pressure spring 5. bearing 14.

The inclined sections 12 of the guide rods 9 as well as the inclined working surfaces 11 of the intermediate elements 6 can be made in the form of conical surfaces

The device works as follows.

When the clutch is engaged, the release bearing 14 is released. The intermediate elements 6 gnzd action of the pushers 8 move in the direction towards the pressure

disk 2 when moving the latter, which leads to clamping of the slave disk 3 between the pressure 2 and master 1 disks and corresponds to the transmission of the terminal torque. When wearing a lead 1,

the slave 3 and the pressure 2 discs are displaced axially in the axial direction by the amount of wear, the guide rods 9 are carried away. The inclined sections 12 of the latter, tend to get out of contact with the stops 10,

provide movement of the pushers 8, which are pressed through the intermediate elements 6 pressure springs 5 to the nominal force.

When turning off the clutch to the release

bearing 14 is applied force. At the same time, the pressure disk 2, as it moves, pre-pushes the pushers 8 apart and compresses the pressure springs 5, which affect the intermediate

elements 6, further pushing the pushers 8, providing a nominal lead pressure plate 2.
