moments and in devices due to small gauges | itov.

A brake is known, which contains a flexible pulley fixed on the working shaft and interacting with its internal P10 top. Sliding brake pads sliding outward.

Not much. This | romosis is that it can make up only small braking moments.

The purpose of the present invention is to increase H a r p | narrowly: Yu sposo (bypath then; rmoza and increase pl: avality of its on-line.

For this purpose, the proposed brake is equipped with a “movable brake drum, covering a flexible H1KI1B and interconnecting: with its inner surface, the friction lining of the inside.

A large torque | with small dimensions is achieved through the use of internal and external shoes, as well as by the expenditure of energy on the deformation of the flexible wheel.

The smoothness of braking is achieved by successive inclusion in the friction steam.

FIG. 1 shows the proposed view, rmoz, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a transverse section of the brake in a retarded state |

The brake contains a steel flexible pulley (B 1, made in the form of a glass. The hub of the glass using CLIPPED is fixed on the working shaft 2. To reduce the axial dimensions of the brake, the flexible pulley can be made

as a ring with a gear connection with a hub.

In 3 brakes installed 1a pad 4, made of a material with a high coefficient of friction. She has two workers

section 5, interacting. when braking with the outer, surface of the thickened part of the flexible pulley. The inner surface of this strap is mounted: it contacts with two inserts 6, also made of a material with high m: coefficient of friction. The liners 6 are closed in blocks 7. The latter can not be moved radially in the guide windows of the flange 8 attached through Hjpointer part 9 to the body 3 of the brake. The movement of the pads 7 is carried out by the cam 10 mounted on the control roller 11. The rotation of this roller may be carried out manually, by an electromagnet, hydraulics, or other known method.

Prior to deceleration, shaft 2 rotates. Along with it, the flexible pulley 1 rotates. When the roller rotates And the cam 10, overcoming the action of the springs 12, mix, the pads 7 radially in the direction of the ueeTip ai. As a result of this, contact with the inner surface of the flexible wedge into the go of the liners 6, and the start of the process is applied. During this period, TO | piM03HO “the moment is even smaller, which contributes to the smoothness of the | p | m; auger. Further pavarot to ulakKa 10 P p “1 It leads to the deformation of the flexible Shkiva and the entrance to the: oita | kt of its outer surface | It is determined by the friction of two pairs of surfaces and the deformation of the flexible pulley, the wind, between the fixed surfaces of friction. When you turn the roller 11 to the other side, the brake is easily turned off.
