RU64167U1 - SHOCK AND TRACTION DEVICE FOR PASSENGER CAR - Google Patents

Abstract

The shock and traction device of a passenger car is designed to mechanically connect the cars and to protect the structure of the car and passengers from longitudinal force impacts arising from the movement. It contains an absorbing apparatus (2) mounted on the spinal beam (1) of the car, made in the form of a central element (3) pivotally connected to the trailing element of the automatic coupler, on which packages of rubber-metal elements (5) are located with the front (6) intermediate (7) and the rear (8) plates interacting with the front stop (10) and the rear (11) formed on the spine beam (1). To reduce the noise level, reduce wear of the elements of the device, as well as to reduce its mass and overall dimensions, a wedge insert (12) is installed in the cross-section with vertical channels between the rear stop (11) and the intermediate plate (7) of the absorbing device (2) struts (14) wedge-shaped in the longitudinal direction. For fastening and crimping packages of rubber-metal elements (5), a clamping device is installed at the end of the central rod (3), which can be made in the form of a threaded assembly (9). 3 s.p. formulas, 3 ill.

Description

The utility model relates to railway transport, in particular, to shock-traction automatic couplers mounted on train cars of constant formation, providing mechanical connection of cars and protecting the structure of cars and passengers from longitudinal force transmitted through an automatic coupler.

In railway transport, automatic couplings are known and used with a shock-traction device, which is mounted on the frame — in the pocket of the spinal beam, an absorbing device of the spring-friction type or with a package of rubber-metal elements interacting with the front and rear stops on the spinal beam of the car frame and made in in the form of a clamp, a traction element, the front end of which is pivotally connected to the shank of the automatic coupler [1].

The known shock-traction device provides reliable retention at a given distance of cars and a locomotive, transmission and mitigation of longitudinal loads that occur when starting a train, moving and shunting, and is safe for maintenance. However, it has a large mass and overall dimensions, and due to the presence of backlash and gaps in its design, it is a source of noise and is subject to intense wear. Its installation on the car is complicated and time-consuming.

The closest analogue of the claimed utility model in technical essence and design is the shock-pull device described in

US patent [2], comprising an absorbing apparatus mounted on the carriage frame made in the form of a package of rubber-metal elements with front, rear and intermediate plates interacting with front and rear stops formed on the carriage frame and a traction element connected to the absorbing apparatus, the front horse of which pivotally connected to the shank of the automatic coupler.

This known device is structurally simpler and has a lower mass, but is also subject to intense wear and is a source of noise due to backlash appearing during its operation.

The technical result that can be achieved by using the inventive utility model is to reduce the mass and overall dimensions of the shock-traction device, eliminate intense wear and reduce noise during movement of the composition.

The specified technical result can be achieved due to the fact that in the shock-pull device containing an absorbing device mounted on the car frame, made in the form of a package of rubber-metal elements with front, intermediate and rear plates at its ends interacting with the front and traction element connected to the plates of the absorbing device, the traction element, the front end of which is pivotally connected to the shank of the automatic coupler, is proposed between the rear stop on the carriage frame ary plate draft gear set fixed to the frame of the car wedge insert.

Wedge insert can be performed -shaped in cross section with vertical racks of wedge-shaped in the longitudinal direction.

The traction element can be made in the form of a central rod on which rubber-metal elements with plates are installed, while at least one rubber-metal element can be located between the intermediate and rear plates on the central rod, fixed by, for example, a threaded connection.

One possible example of the implementation of the claimed utility model is presented in the accompanying drawings.

Figure 1 - presents a diagram of the shock-traction device, a top view.

Figure 2 is a side view.

Figure 3 - shows a wedge insert.

The shock-and-traction device of a passenger car contains an absorbing device 2 mounted on the car frame in the pocket of the spine beam 1, the traction element of which is made in the form of a central rod 3 connected by a hinge assembly 4, for example, spherical with an automatic coupler shank (not shown in the drawings).

On the central shaft 3, packages of rubber-metal elements 5 are installed in contact with the front plate 6, the intermediate plate 7 and the rear plate 8 and pressed by the threaded assembly 9.

On the spinal beam 1 of the car, a front stop 10 is formed, interacting with the front plate 6 of the absorbing apparatus 2 and a rear stop 11, interacting with the intermediate plate 7.

Between the rear stop 11 and the intermediate plate 7, a wedge insert 12 is installed, which is fixed after installation on the spinal beam, for example, by bolts 13 (Fig. 2).

Wedge insert 12 has -shaped profile, close to the channel open to the top, with vertical posts 14 wedge-shaped (see figure 3).

After installing the back stop 11 and the central rod 3 with the packages of rubber-metal elements 5 installed in the pocket of the spinal beam 1, a wedge insert 12 is inserted into the gap between the rear stop 11 and the intermediate plate 7, pressing the absorption device to the front stop 10, compressing the package of rubber-metal elements 5 and eliminating the gaps between the elements of the absorbing apparatus 2 and the spinal beam 1.

The initial compression packages of rubber elements 5 is a threaded node 9.

An absorbing device 2 connected through a hinge assembly 4 to the hitch shaft takes up the loads that arise when the train starts moving, moving and shunting, absorbing and softening transfers them to the spinal beam and the frame of the car, absorbing a significant part of the energy (kinetic energy absorption coefficient is from 0.3 to 0.8).

Due to the exclusion of structural gaps and backlashes in the mechanism of the shock-traction device, there is a significant reduction in the noise level during train movement and the degree of wear of the device elements.
