Problems solved by technology

Since the soft wear-resistant elastic body adopts an integral structure, when the soft wear-resistant elastic body is used for shock absorption, the effect of high-efficiency shock absorption cannot be achieved under the damping effect of the soft wear-resistant elastic body itself. The setting of the elastic body structure also tends to increase the friction between the train and the track when turning, thus shortening the service life of the track

Embodiment Construction

[0032] By the following Figure 1-5 And examples are further illustrated by the present invention:

[0033]A rail transit damping mechanism comprising a sleeper 1 and a track body 3, a track damper 2 is provided on a rail pillow 1, and the track body 3 is disposed on the track damper 2, and the track damper 2 includes a soft wear-resistant elastic plate 21. The soft body wear-resistant support groove 22, the soft body wear-resistant elastic plate 21 is disposed within the soft body wear-resistant elastic support groove 22, and the soft wear-resistant elastic support groove 22 is fixed to the sleeper 1, and the track body 3 is fixed in the soft wear-resistant panel. On the other hand, a multi-group elastic assembly 23 is provided in the soft-resistant elastic support slot 22, and the arrangement of the resilient assembly 23 is provided for the hard-removal connection of the soft wear-resistant elastic plate 21 and the soft wear-resistant elastic support groove 22. The setting of the...

Abstract

The invention relates to a rail transit damping mechanism which comprises a sleeper and a rail body, a rail damper is arranged on the sleeper, and the rail body is arranged on the rail damper; after the structure of an existing soft wear-resistant elastic plate is improved, the improved soft wear-resistant elastic plate is changed into an assembled structure from an integral structure, in this way, in the damping process, the problem that the damping efficiency is low due to the damping effect of the soft wear-resistant elastic plate can be avoided, and in addition, in the elastic plate, through cooperative work of the multiple stages of damping mechanisms, a better damping effect is achieved.

Description

Technical field [0001] The present invention relates to the field of rail transit damping techniques, and in particular to a rail transit damping mechanism. Background technique [0002] The track damper currently used is mainly composed of three parts of the top plate, soft wear-resistant elastomer and the bottom plate. The maximum feature is that iron parts are integrated with rubber vulcanization, and the rubber provides damping performance, and the peripheral bottom plate provides lateral and longitudinal constraints. Vibration and rail retention capability. Since the soft wear-resistant elastomer adopts the integral structure, when the shock absorbers through the soft body, under the action of the soft body wear-resistant elastomer itself, the effect of high efficiency shock absorbing is not possible, while the soft body is resistant to The arrangement of the elastomeric structure is also easily increased by the trains and the track, thereby shortening the life of the track....
