    The invention relates to mechanical engineering, namely to braking devices, and can be used in general mechanical engineering. The goal is to increase the service life of the brake and its reliability by 13 1 IS ensuring the thermal protection of the seals. For this purpose, annular cavities 8 and 14 are provided in the multi-disc brake between disks 1 and 2 and the hub (c) 3. The disk 1 is connected to C 3 via a splined sleeve (SHV) 9. It has the possibility of longitudinal movement along C 3 connected to PN 9 by means of deformable diaphragm seals (DU) 24 and 25. The latter are installed to protect the grooves 11 groove 9 and the slots 12 C 3 from contamination. The controllers 24 and 25 are partially located in annular protective cavities 8 and 14 and fixed by means of rings 31, 32, 33, 35, 36, 37. Heat protection rings 38 and 39 are installed in support 5 and ШВ 9. When the brake is operated, high temperatures are created in the areas of friction of the disks 1 and 2. Due to the location of the remote control 24 and 25 in the annular protective cavities 8 and 14 and the heat shields 38 and 39 above them, the remote control 24 and 25 are protected from high temperatures. 1 hp f-ly, 2 ill. 17 g 16 21 § (Y) ot o ate with 4i-gz SM

    This invention relates to mechanical engineering, namely to braking devices.
    The purpose of the invention is to increase the service life of the brake and the reliability of its operation by providing thermal protection for seals.
    Fig. 1 shows a multi-disc brake, general view; in fig. 2 - compaction assembly on an enlarged scale.
    The multi-disc brake contains the first rotating disk 1, the second internal disk 2 mounted on the hub 3, the axis 4 of which coincides with the axes of the disks 1 and 2, the disk 1 is made integral with the hub 3, for example, connected to it with the possibility of joint rotation through the support 5 using bolted joints 6 and 7 in such a way that between the concentrically located areas of the support 5 and the spline part of the hub 3 there is formed an annular protective cavity 8., The disk 2 is connected to the i slotted sleeve 9 by means of a bolted connection 10, the sleeve 9 is made with internal slot and 11, with which it engages with the outer splines 12 of the hub 3, which ensures the rotation of the disk 2 relative to the hub 3 and the axial movement of the sleeve 9 along the hub 3. On the side of the disk 2 to the hub 3, the rack 13 is rigidly fixed, by means of which between the disk 2 and the hub 3 forms an annular protective cavity 14, the annular cavities 8 and 14 are dimensioned so that the sleeve 9 can move along them
    On two sides of the disk 1, friction inserts 15 and 16 are installed, and c, on both sides. 2, frictional inserts 17 and 18 are installed, Each of the frictional inserts 15-18 contains a friction pad 19, and the thrust disks 20 are pressed against the extreme liners 15 and 18: the discs 1 and 2, together with the friction contours 15-18, An overlay disk 19 and stop discs 20 are placed in the cavity of the bracket 21, On the side of the disk 2, the power hydraulic cylinder 22 with the piston 23 is mounted on the side of the disk 2, moving 1ms about the axis 4, to press the friction linings 19 to the disks 1 and 2. By both sides of the area where the disk 2 is installed. sleeve 9 is connected to the hub 3 by means of a deformation

    The rotatable diaphragm seals 24 and 25 are cylindrical. The seals are installed to protect the slots 11 and 12 from contamination and are embodied in the form of a rolled flexible sheath. The seal 24 is located on the side of the disk 1 and is made with end projections 26 and 27, and the seal 25 is located on the side of the disk 2 and is made with end projections 28 and 29.
    The end protrusion 26 of the seal 24 | is installed in the annular groove 30 of the support 5 and pressed against it with the aid of the ring 31, and the end protrusion 27 is pressed against the end, the sleeves 9 with the aid of the rings 32 and 33.
    The end protrusion 28 of the seal 25 is installed in the groove 34 of the rack
    13 and is pressed against the last bell
    The tube is 35 and the end protrusion 29 is pressed against the end of the sleeve 9 by means of rings 36 and 37.
    Heat protection rings 38 and 39 are installed respectively in the support 5 and in the sleeve 9 concentric with the diaphragm seals 24 and 25, located outside the annular cavities 8 and 14.
    During operation of the brake, the friction linings 19 are pressed against the surface. tons of discs 1 and 2 through the hydraulic cylinder 22, while the temperature in the friction region reaches from 800 to:, which can lead to reduced durability or even destruction of bellows seals. Due to the location of the seals 24 and 25 in the protective cavities 8 and 14. The seals are protected from thermal effects during braking, and Those areas of the seals that are located outside the protective cavities 8 and 14 are protected by rings 38 and 39 located above them.
