Description
Technical field
The utility model relates to a kind of rail traffic vehicles parts, is specifically related to a kind of rail traffic vehicles anti-rolling torsion bar system that is installed between vehicle body of railway vehicle and the bogie truck, belongs to mechanical engineering technical field.
Background technology
The vibration of vehicle mainly contains the degree of freedom of six direction: the bouncing of the stretching vibration of directions X, the yaw vibration of Y-direction, Z direction, around the pitching of Y-axis, around the yawing of Z axis, around the rolling of X-axis.Present rail traffic vehicles bogie truck is two-stage and hangs, and anti-rolling torsion bar system has played the effect that vehicle sidewinders rigidity, control vehicle rolling of regulating.
The mechanism kinematic figure of anti-rolling torsion bar system as shown in Figure 1, M is car body among the figure, E, F are that the torsion bar supporting seat forms, and are installed on the framework, A, B, C, D are rubber bushing or metal joint bearing, can rotate in three directions.As seen from the figure, if do not consider that the supporting seat much smaller with respect to system stiffness forms and the impact of rubber arthrosis, when car body during with respect to bogie truck generation bouncing, two connecting rods are simultaneously toward a direction motion, whole device rotates simultaneously around supporting ball pivot, torsion bar is holding capacity or moment of torsion not, therefore do not affect the bouncing of car body, does not provide equally any additional power or moment of torsion to other the several motions except sidewindering equally.And when occuring when relatively rotating of X-axis namely sidewindered between car body and the framework, left and right sides connecting rod is up-and-down movement in the opposite direction, by reverse arm (FD among the figure, EC) make the torsion bar distortion that twists, torsion bar is antitorque counter torque owing to torsional elasticity produces, this counter torque acts on the vertical force that shows as a pair of opposite sign but equal magnitude on the vertical connecting rod, and this acts on vertical force and has just formed the anti-moment of sidewindering of sidewindering opposite direction with car body on the car body, anti-effect of sidewindering moment will stop car body to sidewinder the increase of angle with respect to bogie truck, thereby suppress sidewindering of vehicle, improve the lateral stability of vehicle.
We can find out from accompanying drawing 1, provide sidewinder rigidity except anti-rolling torsion bar system, two-line suspension spring K also plays a part anti-sidewindering, therefore anti-rolling torsion bar system is the add-on assemble that control system integral body is sidewindered rigidity.
The typical structure of existing track traffic usefulness anti-rolling torsion bar system as shown in Figure 2, mainly consist of the following components: torsion bar axle 1, reverse arm 2, supporting seat assembly 3, vertical connecting device (be used for connection body and bogie truck, comprise ShiShimonoseki nodal axisn 4, vertical connecting rod 5 and shangguan nodal axisn 6).
Design and processes matching requirements according to bogie truck, the torsion bar assembly of present domestic anti-rolling torsion bar system and the connection mode of vertical connecting rod assembly mainly contain two kinds, one is that the reverse arm of torsion bar assembly is being designed to the structure of jag formula with vertical connecting rod junction, and vertical connecting rod assembly is connected with the torsion bar assembly by bolt.Another kind is to process taper hole at reverse arm or integral type bending torsion of bar arm section, cooperates by taper hole to be connected with vertical connecting rod assembly.This dual mode has a common ground, and vertical exactly connecting rod assembly all comprises ShiShimonoseki nodal axisn, the vertical connecting rod body of rod and shangguan nodal axisn, and ShiShimonoseki nodal axisn that vertical connecting rod assembly all passes through on it is connected with the torsion bar assembly.
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 remove to install torsion bar system than large space, easily appearance can't entrucking or with bogie truck on all the other products produce the phenomenon of interfering; Therefore, the vertical connecting rod assembly of traditional anti-rolling torsion bar system and torsion bar assembly and connection mode thereof can't satisfy the designing requirement of bogie truck fully, and this mounting means to anti-side rolling torsion rod has proposed Secretary.
The utility model content
