Compared with the current typical torsion rod types (cylindrical surface interference fit and splined connection), the invention has the advantages that the torsion rod axis and the torsion arms can be assembled through the action of high pressure oil without heating or cooling; the purposes of disassembly and assembly for many times can be realized, and the combined surface of the torsion rod axis and the torsion arms can not be damaged; the magnitude of interference can be accurately adjusted by controlling the displacement in the axial direction; and the type of connecting with a steering frame is more flexible, and the influence caused by the steering frame structure is little.
Description
Technical field
The invention belongs to a kind of rail traffic vehicles with part and preparation method thereof, be meant a kind of rail traffic vehicles anti-side rolling torsion rod axis and preparation method thereof especially.The torsion bar axle mounting is on vehicle body of railway vehicle and bogie truck, when vehicle sidewinders when motion doing, anti-side rolling torsion rod axis twists distortion and produces and to sidewinder rigidity, and with other parts together provide vehicle safety operation required sidewinder rigidity, satisfy the vehicle dynamics performance demands with this, guarantee the safe operation of vehicle.
Technical background
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, all not too adopt in China and Europe, and generally adopt the method in Japan because this scheme is subjected to the restriction of bogie structure, vehicle gauge and line condition;
2) independently roll-resisting torsional rod spring is set, is assemblied between car body and the bogie truck, improve and sidewinder rigidity.Roll-resisting torsional rod spring is a kind ofly to utilize 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.
Vibration of vehicle mainly contains the degree of freedom of six direction: the yaw vibration of the stretching vibration of directions X, Y direction, the bouncing of Z direction, around the pitching of Y-axis, around the yawing of Z axle, around the rolling of X-axis.Present rail traffic vehicles bogie truck is two-stage and hangs (as shown in Figure 1), and roll-resisting torsional rod spring has played the effect (promptly controlling rolling relative between car body shown in the accompanying drawing 1 and the framework) that vehicle sidewinders rigidity, control vehicle rolling of regulating.
The mechanism kinematic figure of roll-resisting torsional rod spring as shown in Figure 2, M is a car body among the figure, E, F form for the torsion bar supporting seat, 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 formed and the influence 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, so do not influence the bouncing of car body, does not provide any additional power or moment of torsion equally to other the several motions except that sidewindering equally.And when taking place when relatively rotating of X-axis promptly sidewindered between car body and the framework, left and right sides Lian Li 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 just to have formed on the car body with car body to vertical force and sidewinders the opposite anti-moment of sidewindering of direction, 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 horizontal stationarity of vehicle.
We can find out from accompanying drawing 2, and the more than roll-resisting torsional rod spring that sidewinders rigidity is provided, and secondary suspension spring K also plays a part anti-sidewindering, so roll-resisting torsional rod spring is to be used for control system integral body to sidewinder the add-on assemble of rigidity.
The structure of existing track traffic usefulness roll-resisting torsional rod spring mainly consists of the following components as shown in Figure 3: torsion bar axle (1 in the accompanying drawing), reverse arm (2 in the accompanying drawing), supporting seat are formed (3 in the accompanying drawing), vertical connecting rod is formed (4 in the accompanying drawing).
As anti-side rolling torsion rod system core parts torsion bar axle, its design and procedure quality control all are the core technologies of anti-side rolling torsion rod system all the time, and its performance and life-span directly influence total system.
In recent years, along with life-span of rail traffic vehicles metal parts and overhaul phase prolong, this life-span to the torsion bar axle had proposed more exacting requirements, thereby designing and developing a kind of novel anti side rolling torsion rod axis, to satisfy new life requirements imperative.
Summary of the invention
The objective of the invention is to the deficiency at existing anti-side rolling torsion rod system core parts torsion bar axle, it is higher to propose a kind of service life, and the novel torsion bar axle construction of good manufacturability.
The objective of the invention is to be achieved through the following technical solutions: a kind of later-model used for rail vehicle torsion bar axle, comprise a torsion bar axle, torsion bar axle two ends are stepped axle, and it is characterized in that: stepped position, torsion bar axle two ends is a kind of curved-surface structure transition of indent formula.The curved surface of described indent formula is for being begun to being lower than little surface indent for the about 5-10 millimeter in end from stepped little axle to the transition position of stepped macro-axis by stepped little axle, and the end of receiving stepped macro-axis by the quadratic curve circular arc.This kind new construction can satisfy requirements such as the rigidity, weight of torsion bar axle, can improve the fatigue life of torsion bar axle again and improve manufacturing process.Technology of the present invention then is first shot-peening, and then ground finish.
