Abstract

The utility model relates to an anti-side-rolling torsion bar device for a railway vehicle, which mainly comprises a torsion bar shaft, torsion arms, a supporting seat, a lower joint shaft of a vertical connecting rod, the vertical connecting rod, an upper joint shaft of the vertical connecting rod and the like, and is characterized in that: the torsion bar shaft is connected with the left and right torsion arms in a conic surface fit way. Compared with the existing typical torsion bar type-cylindrical surface interference fit and spline connection modes, the main innovative points of the utility mode are as follows: the torsion bar shaft and the torsion arms are assembled under the action of high-pressure oil without heating or cooling, the combined surfaces of the torsion bar shaft and the torsion arms are not damaged by multiple disassembly and assembly; and the amount of interference can be precisely adjusted by controlling the axial displacement, the connection mode of the torsion bar shaft and the torsion arms as well as a bogie is more flexible, and the torsion bar shaft and the torsion arms are less affected by a bogie structure.

Description

A kind of used for rail vehicle torsion bar mechanism for preventing side rolling of train carriage

Technical field

The utility model belongs to a kind of rail traffic vehicles parts, is meant a kind of rail traffic vehicles torsion bar mechanism for preventing side rolling of train carriage especially, is installed between vehicle body of railway vehicle and the bogie truck.When vehicle sidewinders when motion doing, anti-side rolling torsion rod system and vehicle secondary suspension together provide vehicle safety to move the required rigidity of sidewindering, and satisfy the vehicle dynamics performance demands with this, guarantee the safe operation of vehicle.

Technical background

Design and processes matching requirements according to bogie truck, the set mode of torsion bar axle and reverse arm mainly contains three kinds both at home and abroad at present: 1) reverse arm and torsion bar axle cooperate (as shown in Figure 1) by the hot jacket cylindrical interference, and this kind structure assembling back torsion bar axle and reverse arm can not be dismantled; 2) reverse arm and torsion bar axle use fastening accessory that reverse arm and torsion bar axial compression is tightly locking by spline fitted (as shown in Figure 2) then, and this kind structure is a detouchable, but the differential seat angle of two ends spline is required very strictness, are difficult to machine-shaping; 3) torsion bar axle and reverse arm adopt one-piece construction (as shown in Figure 3), and promptly the two need not assemble, and are directly replaced by a part, and manufacturing is difficult, installation is subjected to problems such as the more restriction of bogie structure but also exist.

In recent years, along with the requirement of rail traffic vehicles running velocity and traveling comfort is more and more higher, when the design bogie truck, require also more and more stricter to its space structure size and unsprung weight weight-saving, the bulk of bogie truck is also more and more narrower and small, more and more compacter, be difficult to go to install the torsion bar system than large space; This mounting means to anti-side rolling torsion rod has proposed new requirement.In the case, being connected torsion bar with cylindrical interference compares, the spline torsion bar has the advantages that to removably connect, it is less influenced by bogie structure, and therefore comparatively wide range of use is arranged, but for spline interconnection system torsion bar, in manufacturing process and fitting process, but exist some problems, mainly show: 1) positional tolerance of torsion bar axle two ends spline is difficult to guarantee in the manufacturing process, causes dislocation easily, thereby influence is used; 2) the spline positional tolerance of left and right sides reverse arm must adopt the accurate localization frock to guarantee; 3) location of reverse arm and torsion bar axle need be added other parts and could be realized in fitting process; Therefore designing and developing that a kind of novel anti side rolling torsion rod system of not only being convenient to process but also being convenient to install forms has been extremely urgent.

The utility model content

The purpose of this utility model is can not adapt at the anti-side rolling torsion rod system of existing structure the requirement of novel rail vehicle, a kind of easy manufacturing is provided, more convenient novel torsion bar mechanism for preventing side rolling of train carriage is installed.

The purpose of this utility model is achieved through the following technical solutions: a kind of later-model used for rail vehicle torsion bar mechanism for preventing side rolling of train carriage, mainly partly form by torsion bar axle, reverse arm, supporting seat, vertical connecting rod ShiShimonoseki nodal axisn, vertical connecting rod, vertical connecting rod shangguan nodal axisn etc.It is characterized in that: the connection mode that the torsion bar axle cooperates with left and right sides reverse arm employing circular conical surface.Torsion bar axle and reverse arm can assemble and dismantle by high pressure oil.

Compare with the spline interconnection system with existing representative type torsion bar type-cylindrical interference formula, main innovate point of the present utility model is:

1) torsion bar axle and reverse arm can be realized assembling by the effect of high pressure oil, need not heating or cooling;

2) repeatedly dismounting be can realize, torsion bar axle and reverse arm faying face do not damaged;

3) can accurately adjust its magnitude of interference by the control longitudinal travel;

4) will be more flexible with the connection mode of bogie truck, it be less influenced by bogie structure;

The specific embodiment

Accompanying drawing 4 has provided embodiment of the utility model, and the utility model will be further described below in conjunction with accompanying drawing.

From accompanying drawing 4 as can be seen, the utility model is an a kind of later-model used for rail vehicle anti-side rolling torsion rod system, and principal character is: torsion bar axle 1 adopts the cone match interference to be connected respectively with reverse arm 2 in this system.

Main processes of the present utility model is as follows:

Torsion bar axle: blanking--＞prtreatment--＞conical surface prtreatment--＞heat treatment--＞the fine limit work--＞grinding conical surface--＞non-destructive test--＞shot-peening

--＞prtreatment--＞conical surface prtreatment--＞heat treatment--＞fine limit work--＞grinding conical surface--＞non-destructive test of reverse arm: blanking

Assembling: method 1: reverse arm heating--＞reverse arm cooperates with torsion bar axial cone face and locatees--＞reverse arm cooling;

Method 2: the reverse arm conical surface and torsion bar axial cone face are adjacent to--＞in reverse arm and the oiling of torsion bar axial cone face joint--＞make reverse arm move to the position of requirement by pressure--＞emptying
