Description
Technical field
This utility model belongs to a kind of rail traffic vehicles bogie parts, particularly relates to a kind of rail traffic vehicles and uses
Anti-side rolling torsion rod forms, and is arranged between vehicle body of railway vehicle and bogie.
Background technology
The vibration (moving) of rail vehicle mainly has the degree of freedom of six direction to vibrate: stretching vibration, yaw vibration, drift along
Vibration, nodding, yawing, rolling (as shown in Figure 1).Current rail traffic vehicles bogie is two-stage and hangs
Hanging, anti-side rolling torsion rod composition serves regulation vehicle and sidewinders rigidity, controls the effect of vehicle rolling (moving).When vehicle exists
When sidewindering motion, anti-side rolling torsion rod composition with vehicle secondary suspension vehicle safety provided along run needed for sidewinder rigidity,
The requirement of dynamics of vehicle performance is met, it is ensured that the safe operation of vehicle with this.
The typical structure of existing track traffic monoblock type anti-side rolling torsion rod composition, mainly comprises the following steps: curved
Torsion bar shaft, installation (support) seat, oscillating bearing, vertical connecting rod (for connection body and bogie), rubber bushing.The most overall
Formula anti-rolling torsion bar for railway vehicle forms, and curved torsion bar shaft and vertical connecting rod are connected by the taper pin structure on oscillating bearing, so
Afterwards by using helicitic texture tightly to be combined with curved torsion bar shaft by oscillating bearing, not only turned round due to torsion bar shaft but also curved special
Stress form, the most curved torsion bar shaft for product metal structure require concordance the best, torsion bar shaft surface will be formed
Consistent with the hardness of core, the highest, the difficulty of processing bringing taper hole is very big, and the profile tolerance of taper hole ensures very poor, processing
Cost is the highest, simultaneously because taper hole and oscillating bearing are separate machined, wimble structure is in engagement process, and actually active composition surface is not
It is the highest；The most in use for some time, taper hole and the abrasion of taper pin, more reduce composition surface, wimble structure can be brought
Connecting and loosen, owing to taper hole and taper pin are all rigid bodies, easily form shock loading, shock loading can cause system abnormal sound, shadow
Ring the comfortableness in driving conditions, if shock loading is excessive will damage taper pin structure simultaneously, causes taper pin to rupture, make anti-side
Rolling torsion bar system lost efficacy, and some arrange serious security incident may to cause train rollover, derailing etc..

After the end time, abrasion loosens, and forms impact abnormal sound and shock loading, affects the Function of whole anti-side rolling torsion rod composition system.
Therefore, designing one the most safe and reliable, the anti-rolling torsion bar system the most not affecting riding comfort is just particularly important, especially
It is to improve anti-side rolling torsion rod composition dependability, solves again what current monoblock type anti-rolling torsion bar system existed
Difficult processing, coordinate that reliability is not enough, use after wear and tear cause abnormal sound, the problem such as shock loading.
In prior art, the Chinese utility model of Patent No. ZL201320409010.1 discloses a kind of used for rail vehicle
Anti-side rolling torsion rod forms, and including torsion bar assembly and connecting rod, described torsion bar assembly includes torsion bar shaft and two, left and right reverse arm, described
Torsion bar shaft is curved torsion bar shaft, its two ends bending, often hold dogleg section a length of torsion bar shaft total length 1/10th；Described torsion
Arm is V shape or pin bushing-type reverse arm, and described reverse arm uses forging molding；Described torsion bar the tip of the axis couples with reverse arm
Mode is interference fit joint, thread connection, spline connection, welding or pin shaft joint.Described torsion bar shaft is U-shaped torsion bar shaft, by directly turning round
Bar axle bending is U-shaped forming.This utility model problem that mainly solution anti-side rolling torsion rod composition installing space is limited, but not
Anti-side rolling torsion rod can either be improved by proposition and form dependability, current monoblock type anti-rolling torsion bar system can be solved again and deposit
Difficult processing, coordinate that reliability is not enough, use after wear and tear cause abnormal sound, the technical scheme of the problem such as shock loading.
