Abstract

FIELD: transportation.

SUBSTANCE: method for suspending bellows in a coupled vehicle is in using supporting devices for the bellows. As a supporting tool, one or more universal self-centering systems are used. A universal self-centering system contains an internal and an external base. Three or more external rollers are fixed on the external base. Three or more internal rollers are fixed on the internal base. The internal and external rollers are connected together by a closed rope. The external base covers the internal base. Coupled carriages are used as an external base of a universal self-centering system. The vehicle bellows rest on the inner base of the universal self-centering system.

EFFECT: improving the efficiency of the method for suspending bellows.

Description

The invention relates to couplers for vehicles.

A known method of suspension of a bellows in coupled vehicles, in which the middle part of the bellows is supported by additional devices mounted on the vehicle body. The middle part of the bellows is connected to this accessory (DE10238110A1).

The disadvantage of this method is the relatively large volume of devices and low efficiency.

The aim of the invention is to reduce the occupied volume of devices for hanging bellows and increase efficiency.

This goal is achieved by the fact that as devices for hanging the bellows using a universal self-centering system. The universal self-centering system contains an internal and external base. On the external base 3 or more external rollers are fixed with the possibility of rotation relative to their axes. On the inner base 3 or more inner rollers are fixed with the possibility of rotation relative to their axes. The number of outer and inner rollers is the same. The inner and outer rollers are interconnected by a closed cable or chain. When a cable or chain moves along its perimeter, all the rollers rotate with the same linear speed. The direction of rotation of the inner and outer rollers is mutually opposite. The outer base covers the inner base. Lockable carriages of the vehicle are used as the external base of a universal self-centering system. The vehicle bellows rests on the inner base of a universal, self-centering system.

One of the properties of a universal self-centering system is that when an external force P acts on an internal base, this force is distributed between the outer rollers by a tensioned cable. Another property of the universal self-centering system is that when the geometric parameters of the external base are changed, the internal base will move to a new central position relative to the external base.

In a specific embodiment, the bellows 15 is located between two cars 5, 6 of the vehicle. At the same time, 5, 6 fulfill the role of the external foundation of the self-centering system. The outer rollers 11, 12, 13, 14 are fixed by means of hinges 17 and racks 2 rotatably relative to the axes 19. The inner rollers 7, 8, 9, 10 are fixed on the inner base 1 with the possibility of rotation relative to the axes 19. The inner and outer rollers are connected interconnected by a cable 16. A spring 18 is fixed to the cable gap for tension. When the angle between the cars 5, 6 changes, the distance 20 changes, but the position of the base 1 always remains central. On the other side of the wagons is a similar universal self-centering system. If the angle between the cars differs from 180 degrees, then the distance 20 on the left side of the car will differ from the distance 20 on the right side of the car, but the inner bases 1 on the left and right will be exactly in the middle between the cars 5, 6. Traverse 4 is fixed to the central edge of the bellows and using the rod 3 is fixed on the inner base. As a result, the traverse 4 rests on cars 5.6 through a universal self-centering system and is always located in the middle of the cars, regardless of the angle between them.

The support of the middle part of the bellows on the inner base of the universal self-centering system allows to reduce the rigidity of the bellows and, in particular, the size H.

In a universal self-centering system, rollers, pulleys or sprockets connected by a closed belt, cable or chain can be used.
