The rubber spherical hinge adopts the structure that a rubber layer is wrapped outside a cylindrical metal mandrel and a metal jacket is sheathed outside the rubber layer; and the metal joint bearing adopts the structure that a reverse arc-shaped metal sleeve matched with the spherical surface of a metal joint bearing mandrel is sheathed outside a spherical metal mandrel and is clamped in a metal joint bearing hole of the torsion rod shaft by a snap ring. The upper joint of the vertical connecting rod adopts the rubber spherical hinge, so that noise can be lowered and vibration can be reduced; and the lower joint of the vertical connecting rod adopts the metal joint bearing, so that the size is compact and large-angle torsion and deflection can be realized.
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.
Technical background
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, and the anti-side rolling torsion rod system has played the effect that vehicle sidewinders rigidity, control vehicle rolling of regulating.
The mechanism kinematic figure of anti-side rolling torsion rod system as shown in Figure 1, 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 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 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 1, provide sidewinder rigidity except the anti-side rolling torsion rod system, secondary suspension spring K also plays a part anti-sidewindering, so the anti-side rolling torsion rod system is used for control system integral body to sidewinder the add-on assemble of rigidity.
Existing track traffic with the typical structure of anti-side rolling torsion rod system as shown in Figure 2, mainly consist of the following components: torsion bar axle 1, reverse arm 2, supporting seat 3, vertical connecting device (be used to connect car 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, domestic and international vertical connecting device is made up of vertical pipe link, upper joint, hypozygal usually, and last hypozygal generally has two kinds of versions: 1) go up hypozygal and all adopt rubber arthrosis (metal-rubber joint product), this kind structure is because the rubber layer that adopts High molecular material to make has stronger vibration and noise reducing effect; 2) go up hypozygal and adopt the metal joint bearing, this structure adopts standardized metal joint bearing, is easy to realize the normalisation and the General design of product, and Assembly ﹠Disassembly is convenient, steering angle big (circumferentially corner reaches 360 °, and the angle of inclination maximum can reach 40 °).
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.The vertical connecting device effect of vibration and noise reduction of rubber arthrosis formula is obvious, but size is bigger than normal, particularly if realize the deflection angle of wide-angle, then must oad make very big, this tends to cause the bogie truck space more nervous or even do not have sufficient installing space and offer rubber arthrosis; By contrast, metal joint has then just solved this problem, but its shortcoming is that noise is very big when driving a vehicle, and does not almost have effectiveness in vibration suppression, and the overcoat of metal joint and interior cover produce relative motion, weares and teares easily and cause the two gap increase noise to occur and produce destroying.Therefore design and develop compact and the anti-side rolling torsion rod with vibration and noise reducing effect of a kind of bulk with the vertical connecting device particularly necessity that seems.
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, and a kind of anti-side rolling torsion rod system with novel vertical connecting device is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of later-model used for rail vehicle anti-side rolling torsion rod system, 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: hypozygal adopts the joint of different structure respectively on the vertical connecting rod, and wherein, vertical connecting rod upper joint adopts rubber bushing, and vertical connecting rod hypozygal adopts the metal joint bearing.Described rubber bushing is at columned metal axle outer wrapping one deck rubber layer, is with a metal-coating at rubber layer again; Described metal joint bearing is for to have an anti-arcuation metallic sheath that matches with the spherical face of metal joint bearing spindles at spherical metal cores outer shaft sleeve, and anti-arcuation metallic sheath is stuck in the metal joint bearing hole of torsion bar axle by snap ring.
Main innovate point of the present utility model is: compare with the metal joint formula with the vertical connecting device of existing representative type-rubber bushing formula, the utlity model has following advantage:
1) vertical connecting rod upper joint adopts rubber bushing, can reduce noise, alleviates vibration;
2) vertical connecting rod hypozygal adopts the metal joint bearing, and compact dimensions can be realized reversing and yaw motion of wide-angle.
