Abstract

The invention relates to the field of mechanical engineering and can be used in multi-disk friction devices. The aim of the invention is to increase reliability by ensuring uniform lubrication of the package of friction discs. For this, the clutch contains outer 4 and inner 5 drums. A package of friction disks 3 is installed between the pressure 1 and the stop 2 disks. In the inner drum 5 there are radial holes 6 and longitudinal channels 8 of variable section. The longitudinal channels can be made in the form of grooves open to the center of the drum or closed. The holes 6 and the channels 8 communicate with each other in the zones of their maximum area of the river section. When the oil is fed into the channel 8, it reaches the edges of the through radial holes 6 and is evenly fed over the whole oil into the package of the Friction discs 3. 2 Cp. f-ly, 2 ill. a 9 (L with co. eo with co.

Description

The invention relates to mechanical engineering and can be used in multi-disk friction devices operating in oil, for example, in locking clutches and brakes.

The purpose of the invention is to increase reliability by ensuring uniform lubrication of the package of the friction discs,

Figure 1 shows the proposed coupling; in fig. 2 - section A - A in FIG.

The friction clutch consists of a pressure 1 and a stop 2 discs, located between them a package of 3 friction discs connected to the outer 4 and inner 5 reels. The series has uniformly circumferentially along the cylindrical forming row of through radial holes 6 for the supply of lubricant to the package of 3 discs and the collar 7, which limits the outflow of lubricant from the internal cavity of the drum 5 in the axial direction. The through radial holes in each row are equally spaced from each other. Each row of holes is mated with its channel 8 of cylindrical or prismatic shape, recessed into the body of the drum 5 by 3 mm or more so that their line of junction is from the bottom of the groove at a height of at least 2 mm.

Channels 8 are made either to the entire length of the package 3., friction discs, if necessary, cross the hub 9 of the drum 5, or in part of the rim

The clutch works as follows.

When you turn on the clutch pressure plate

moving axially

Squeeze-1 package of 3 friction discs and thereby ensures the transfer of torque from one drum 10 to another due to the frictional forces between the disks.

When it is turned off, the pressure plate moves away from the bag, the WHICH wheels diverge in the axial direction, and the transfer of torque from one drum to the other stops. The clutch is idling. At all stages of the clutch operation, the oil from the lubrication system is supplied to the inner drum 5, fills the channels 8. until its level reaches the edges of the through radial holes 6. After that, when the next batch of oil enters the channels 8, it starts to flow. Relivat 12C in the holes 6 and through them is fed to the package of 3 discs, and the oil flows simultaneously into all through radial holes 6 evenly across the entire width of the package of 3 discs. This ensures, independently of the DESIGN of the inner drum 5 and the conditions for supplying lubricant to it, equal conditions for the formation of the oil layer on all surfaces of the friction of the package 3 and, accordingly, equal conditions for the heat sink and wiring of the discs when the coupling is turned off.

The friction clutch, containing those 7 and the end walls of the channels 8 the outer and the inner drums, are axially slit 10 at the maximum joint depth of the radial through holes 6 with the side surfaces of the grooves, the main and pressure discs, a package of friction discs placed between them, and on the internal drum of the upper 45 yen radial through holes.

When applying lubricant to the drum 5, for example, to the left of the hub 9 (figure 1), to the right of it on the rim of the drum restrictive collar, similar to collar 7, is absent, its function is located -placed along its generators, and longitudinal channels with end the walls communicating with the through radial holes, about t and i 50 heme, which, in order to increase reliability by ensuring uniform lubrication of the package of friction discs, the longitudinal channels cut into the cross section of the cross section 8.

With thicknesses: drum rim 5 bo-. 55 semolina widths, and their number is equal to 12 mm instead of channels 8, perform a series of end-to-end radial holes with axial drilling in the rim, fouling, communicating with longitudinal overhangs from both ends and combined in squares in zones -size oil collector ring type (ring-their cross-section.
