Abstract

The invention discloses a secondary suspension device with an air spring for an urban rail vehicle. The secondary suspension device comprises the air spring arranged at the upper part; a slide mechanism is arranged at the lower part of the air spring; the slide mechanism comprises two slideways fixed on both sides of a bogie frame; two pulley mechanisms are respectively arranged on the two slideways, and are connected with each other through a web plate; a rotating center is also formed on a central axis of the bogie frame; and the middle part of the web plate is pivoted with the rotating center. A plurality of holes are formed on the web plate. The pulley mechanisms adopt bearing type pulleys. In the invention, the lateral displacement between the vehicle and the bogie frame can be effectively increased, and the operating safety of the urban rail vehicle and the comfort when a passenger takes the vehicle can also be fully ensured.

Description

City rail vehicle secondary suspension air spring device
Technical field
The present invention relates to city rail vehicle secondary suspension air spring device.
Background technology
As shown in Figure 1, the extensive air bellow that adopts of city rail vehicle mainly partly is made up of loam cake 31, clasp 32, rubber metal pad 33, capsule 34 and base plate 35 etc. both at home and abroad at present, it is installed between truck frame and the car body, to transmit vertical force and transverse force, the relative motion that produces between balancing steering frame and the car body, the stationarity of assurance vehicle operating.During use, this capsule 34 and rubber metal pad 33 are operated in series connection, and its height is irrelevant with loading status, only control by the inflation of advancing to capsule 34.When the et out of order of capsule zone, perhaps during the air supply et out of order, car body drops on the rubber metal pad 33, rubber metal pad 33 will provide part vertical with lateral stiffness and distortion, make the vehicle maintenance that under the deceleration situation, comes back to the base.At this moment, the traveling comfort of taking and the stationarity of train operation can be subjected to influence in various degree.
Summary of the invention
The objective of the invention is to deficiency at the air bellow of widespread use in domestic existing subway, the city rail vehicle secondary suspension device, a kind of later-model city rail vehicle secondary suspension air spring device is provided, it can increase the cross travel of vehicle and truck frame, and can fully guarantee city rail vehicle safety in operation and passenger's travelling comfort.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of city rail vehicle secondary suspension air spring device, comprise the air bellow that is arranged at top, the bottom of this air bellow is provided with slide mechanism, this slide mechanism comprises two slideways that are fixed on the truck frame both sides, two pulley mechanisms are arranged at respectively on two slideways, and two pulley mechanisms couple together by web, also be provided with centre of gration on the central axis of this truck frame, this web middle part is hubbed on this centre of gration.
Offer several holes on this web.
This pulley mechanism adopts the bearing-type pulley.
Compared with prior art, the beneficial effect that the present invention had is: the present invention is by setting up slide mechanism in the bottom of air bellow, air bellow can be slided on slide mechanism, when vehicle passes through curve, can make vehicle by sharp radius curve the time, have the cross travel bigger than original air bellow, and have the characteristics of original good twisting performance of air bellow and displacement reliability concurrently, can fully guarantee the safety of city rail vehicle operation and the traveling comfort that the passenger takes.
Description of drawings
Fig. 1 is the structural representation of existing air bellow;
Fig. 2 is the structural representation of one embodiment of the invention;
Fig. 3 is a slide construction scheme drawing of the present invention.
The specific embodiment
As Fig. 2, shown in Figure 3, one embodiment of the invention comprises the air bellow 1 that is arranged at top, and the bottom of this air bellow 1 is provided with slide mechanism 2.This air bellow 1 adopts double-layer rubber heap formula structure, is made up of loam cake 11, capsule 12, rubber metal pad 13, lower shoe 14.This slide mechanism 2 comprises two slideways 21, web 22, centre of gration 23, pulley mechanism 24.This two slideway 21 is fixed on the truck frame, can guarantee that the pulley mechanism 24 in the secondary suspension system slides in fixing slideway 21.Web with holes of two pulley mechanism 24 usefulness 22 connects, and web 22 guarantees the synchronous rotation of two pulley mechanisms 24 by being arranged at the centre of gration 23 on the truck frame.This pulley mechanism 24 adopts the bearing-type pulley.
When vehicle passes through curve, slide mechanism 2 of the present invention is used with air bellow 1, vertical stiffness is provided by air bellow 1, can also can fully guarantee the safety of city rail vehicle operation and the traveling comfort that the passenger takes by the cross travel amount between slide mechanism 2 increase vehicles and the bogie truck simultaneously.
The air bellow of above-mentioned employing double-layer rubber heap formula structure specifies the present invention, but the present invention is not limited to the air bellow of double-layer rubber heap formula structure, general air bellow (as multilayer rubber heap formula, cone rubber heap formula etc.) all can be applicable to the present invention, does not do too much explanation at this.

Claims (3)
