Abstract
The utility model relates to an anti-rolling torsion bar for a railway vehicle, which is composed of a torsion bar shaft, a twisting arm, a supporting seat, a lower joint shaft of a vertical connecting pole, a vertical connecting pole, an upper joint shaft of the vertical connecting pole and the like. The anti-rolling torsion bar for the railway vehicle is characterized in that: the torsion bar shaft and the left and right twisting arms adopt different connecting ways respectively; wherein one end of the anti-rolling torsion bar is movably connected and the other end thereof is fixedly connected, so as to replace interference connection of the original two ends or spline connection. On the premise of keeping the spline connection of the torsion bar, as one end is in a movable connecting structure and the other end thereof is in a fixed connecting structure, when processing the torsion bar shaft and the twisting arm, the processing difficulty is greatly reduced without considering position tolerance; when in assembly of the torsion bar shaft and the twisting arm, the movable connecting end is assembled firstly and the fixed connecting end is installed by a simple locating tooling, thereby being capable of ensuring the mounting surfaces of the twisting arms at two ends to be kept in the same plane.
Description
Technical field
The utility model belongs to a kind of rail traffic vehicles parts, is meant a kind of rail traffic vehicles anti-side rolling torsion rod system 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.
Background technology
Vertical stiffness is less, equivalent deflection is big owing to having for air bellow, is fit to very much the requirement of guideway vehicle secondary suspension development, has obtained increasingly extensive application in the last few years.Because the air bellow vertical stiffness is little, in vehicle operating, can cause the angle of sidewindering of vehicle to increase, it is less to make vehicle sidewinder rigidity, even the phenomenon of unstability appears sidewindering, cause vehicle safety and steadily drive ability reduction, this rigidity of sidewindering that just needs to increase vehicle separately be sidewindered angle to limit it, thereby improves the anti-performance of sidewindering of vehicle, but can not influence the drifting along of vehicle, yaw simultaneously again, the vibration characteristic of direction such as stretch, nod and shake the head.Reach this purpose, the method for main utilization has two kinds both at home and abroad at present:
1), strengthen two be the transverse pitch of air bellow to increase its angular rigidity, sidewinder rigidity thereby improve.But, and generally adopt the method in Japan because this scheme is all not too adopted by be limited in China and the Europe of bogie structure and vehicle gauge and line condition;
2), independently anti-side rolling torsion rod system is set, be assemblied between car body and the bogie truck, improve and to sidewinder rigidity.The anti-side rolling torsion rod system a kind ofly utilizes metal elastic rods to produce torsional deflection when being subjected to torsional interaction and the spring of antitorque commentaries on classics counter torque is provided.This scheme can be implemented under existing vehicle and line condition, so method has obtained using widely in China and Europe.
Existing track traffic mainly consists of the following components: torsion bar axle 1, reverse arm 2, supporting seat 3, vertical connecting rod ShiShimonoseki nodal axisn 4, vertical connecting rod 5, vertical connecting rod shangguan nodal axisn 6 with the structure of anti-side rolling torsion rod system as shown in Figure 1.
According to the design and processes matching requirements of bogie truck, the set mode of torsion bar axle and reverse arm mainly contains three kinds both at home and abroad at present: one is that reverse arm and torsion bar axle pass through the hot jacket interference fit, and this kind structure assembling back torsion bar axle and reverse arm can not be dismantled; Its two be reverse arm and torsion bar axle by cooperations such as splines, use fastening accessory that reverse arm and torsion bar axial compression is tightly locking then, this kind structure is a detouchable, but the differential seat angle of two ends spline is required very strict, is difficult to machine-shaping; It three is that torsion bar axle and reverse arm adopt one-piece construction, and promptly the two need not assemble, and is directly replaced by a part, makes difficulty, problems such as being subjected to the more restriction of bogie structure is installed 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, the spline torsion bar is owing to be to removably connect, it is less influenced by bogie structure, therefore comparatively wide range of use is arranged, but for spline interconnection system torsion bar, but exist some problems in manufacturing process and process, mainly show: the positional tolerance of torsion bar axle two ends spline is difficult to guarantee in the manufacturing process, cause dislocation easily, thereby influence is used; The spline positional tolerance of left and right sides reverse arm must adopt the accurate localization frock to guarantee; Thereby to design and develop that a kind of novel anti side rolling torsion rod system of being convenient to install forms be 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 anti side rolling torsion rod is installed.
The purpose of this utility model is achieved through the following technical solutions: design a kind of later-model used for rail vehicle anti-side rolling torsion rod, mainly partly be made up of 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 torsion bar axle adopts different connection modes respectively with left and right sides reverse arm, wherein an end for flexibly connect and the other end for captiveing joint, to replace original two ends all be the interference connection or all be spline bonded assembly version with this.
The utility model is a fixed connection structure because an end has the movable connection structure other end under the prerequisite that has kept spline interconnection system torsion bar advantage, in the man-hour that adds of torsion bar axle and reverse arm, does not need the too much positional tolerance of consideration, greatly reduces difficulty of processing; When reverse arm and the assembling of torsion bar axle, only need to flexibly connect end earlier and assemble simultaneously, install and fix coupling end by simple positioning tool again, can guarantee that two ends reverse arm attachment face remains in the same plane.Therefore, the positional tolerance that can effectively solve torsion bar axle two ends spline in the spline connection manufacturing process is difficult to guarantee, cause dislocation easily, thereby influence is used; The spline positional tolerance of left and right sides reverse arm must adopt the accurate localization frock could guarantee two hang-ups.
Main innovate point of the present utility model is:
1) the torsion bar axle adopts respectively to flexibly connect with left and right sides reverse arm and is connected with permanent fixation.
2) will be more flexible with the connection mode of bogie truck, it be less influenced by bogie structure.
3) compare with traditional spline torsion bar, it will be more simple making, the positional precision of easier assurance assembling back two reverse arms.
4) maintenance maintenance is more convenient, and the active connection place is as wearing and tearing occurring, and the reverse arm that only needs to change this end gets final product.
