Abstract

The utility model relates to a carriage connection cab apron structure for a railway vehicle. The carriage connection cab apron structure comprises an upper cab apron and a lower cab apron, wherein the upper cab apron and the lower cab apron are in bridge joint; and at least one rolling device which enables rolling motion to be generated between the upper cab apron and the lower cab apron is arranged between the upper cab apron and the lower cab apron. The carriage connection cab apron has a simple whole structure, a group of shock absorption universal balls are arranged on the upper cab apron and can roll between the upper cab apron and the lower cab apron, so that sliding friction between the upper cab apron and the lower cab apron can be avoided when the vehicle encounters a slope, a turn and other special road conditions, the sliding friction is changed into rolling friction, the nose can be reduced, and the passenger comfort can be improved.

Description

The used for rail vehicle compartment connects the cab apron structure
Technical field
The utility model relates to the interface channel between two adjacent in a kind of guideway vehicle compartments, and particularly a kind of compartment connects the cab apron structure, belongs to guideway vehicle manufacturing technology field.
Background technology
In the guideway vehicle such as subway, train, have the passage that passes through for the passenger between two compartments, the connecting portion in two compartments is provided with and connects cab apron as the passageway bridge of passage, and cab apron is two, can dock, also can cross-over connection.In traditional guideway vehicle, adopt the drift structure between two cab aprons, be beneficial to two movement and rotations between the cab apron.
Traditional cab apron structure, in the situation that Vehicle Driving Cycle arrives the special road conditions such as ramp, bend, the connection cab apron friction aggravation of two array carriages, noise strengthens, and has reduced passenger's travelling comfort.
The utility model content
The utility model main purpose is to address the above problem and is not enough, and a kind of noise that effectively reduces is provided, and the used for rail vehicle compartment that improves passenger comfort connects the cab apron structure.
For achieving the above object, the technical solution of the utility model is:
A kind of used for rail vehicle compartment connects the cab apron structure, comprise cab apron and lower cab apron, cross-over connection between described upper cab apron and the described lower cab apron is provided with at least one on described and can makes the tourelle that produces rolling movement on described between cab apron and the lower cab apron between cab apron and the lower cab apron.
Further, described tourelle is multi-directional ball.
Further, described tourelle is the shock absorbing type multi-directional ball.
Further, be provided with at least one permanent seat between cab apron and the lower cab apron on described, described multi-directional ball is fixed in the permanent seat.
Further, described permanent seat is fixed on the lower surface of described upper cab apron, the upper surface touch scrolling of the spheroid in the described multi-directional ball and described lower cab apron.
Further, described tourelle is provided with two at least.
Further, described tourelle is arranged symmetrically with along the line of centers of described upper cab apron and described lower cab apron.
Content to sum up, used for rail vehicle provided by the utility model compartment connects the cab apron structure, integral structure is simple, fills one group of able to suppress shock formula multi-directional ball at upper cab apron, and it is rolled between upper and lower two cab aprons, like this, when running into the special road conditions such as ramp, bend, avoided the up and down cliding friction of two cab aprons, make cliding friction become friction of rolling, reduce noise, and then improved passenger comfort.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1.
As depicted in figs. 1 and 2, upper cab apron 1, lower cab apron 2, pivot structure 3, end wall of car body 4, permanent seat 5, shock absorbing type multi-directional ball 6.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1, in the guideway vehicles such as subway, train, the connecting portion in two compartments is provided with the connection cab apron that consists of passageway bridge.
Connecting cab apron is two, is respectively cab apron 1 and lower cab apron 2, mutually cross-over connection connection between upper cab apron 1 and the lower cab apron 2, and another side of upper cab apron 1 and lower cab apron 2 is captiveed joint with end wall of car body 4 by two pivot structures 3 respectively.
Upper cab apron 1 and lower cab apron 2 are between the position of mutually cross-over connection, be provided with at least one tourelle, tourelle can make between cab apron 1 and the lower cab apron 2 and produce rolling movement, become friction of rolling by traditional cliding friction between upper cab apron 1 and the lower cab apron 2, can decrease between cab apron 1 and the lower cab apron 2 because the noise that the phase mutual friction produces.In the present embodiment, tourelle preferably adopts multi-directional ball, for further reducing noise, more preferably adopts shock absorbing type multi-directional ball 6.For keeping the balance of upper cab apron 1 and lower cab apron 2, avoid cab apron 1 and the lower cab apron 2 local cliding frictions that produce, shock absorbing type multi-directional ball 6 arranges 2 at least, and in order to guarantee the stressed homogeneity of multi-directional ball, shock absorbing type multi-directional ball 6 is arranged symmetrically with along upper cab apron 1 and lower cab apron 2 line of centerss.In the present embodiment, be provided with three shock absorbing type multi-directional ball 6.
Lower surface at upper cab apron 1 is fixed with three permanent seats 5, shock absorbing type multi-directional ball 6 of each permanent seat 5 interior installation, adapter plate 5 is fixed on the lower surface of cab apron 1, in the vehicle real-world operation, upper cab apron 1 and shock absorbing type multi-directional ball 6 since the Action of Gravity Field automatic pressing on lower cab apron 2, the spheroid in three shock absorbing type multi-directional ball 6 and the upper surface touch scrolling of lower cab apron 2.Like this, run into when vehicle in the situation of the special road conditions such as ramp, bend, shock absorbing type multi-directional ball 6 namely comes rollback moving at lower cab apron 2, become friction of rolling by traditional cliding friction between upper cab apron 1 and the lower cab apron 2, effectively reduce the friction noise between cab apron 1 and the lower cab apron 2, improved passenger comfort.
As mentioned above, given scheme content can derive similar technical scheme in conjunction with the accompanying drawings and embodiments.In every case be the content that does not break away from technical solutions of the utility model,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
