Abstract
The utility model relates to a torsion bar shaft protection device of anti -rolling torsion bar system, protection device installs at anti -rolling torsion bar system torsion bar epaxially, including pin thread and box, protection device is the hollow cylinder, and the opening part is equipped with the closing device, the closing device includes pin thread and box, pin thread and box cooperation locking. The utility model discloses a protective sheath is protected the torsion bar axle, can effective resistance external grit etc. To the impact and the waterproof effect of torsion bar axle.
Description
Technical field
The utility model belongs to a kind of rail traffic vehicles parts, refers to a kind of anti-rolling torsion bar system torsion bar shaft fender guard especially, for the protection of the safety and reliability of core component in anti-rolling torsion bar system.
Background technology
When high speed train operate in sandstone comparatively multi-route time, can sandstone be rolled.The sandstone splashed, may pound on the anti-rolling torsion bar system that is arranged on bogie truck, cause anti-rolling torsion bar system surface damage, shorten the service life of anti-rolling torsion bar system, reduce the safety in utilization of anti-rolling torsion bar system, even cause derailment accident.
For ensureing the application safety of anti-rolling torsion bar system, need protect anti-side torsion bar system, especially producing torsional deflection for car body and the torsion bar shaft of sidewindering rigidity is provided.The anti-rolling torsion bar system of current use, does not all design the fender guard that anti-sandstone injure by a crashing object.
Prior art: application number: 201120514982.8 are called: a kind of patent of side-rolling resistant torsion rod system for railway vehicle fender guard, comprise anti-rolling torsion bar system of rail vehicle, a shock proof protection sleeve is had at the torsion bar shaft overcoat of anti-rolling torsion bar system of rail vehicle, protection sleeve and torsion bar shaft adopt free-running fit, are protected torsion bar shaft by a kind of protection sleeve having shock resistance good; Torsion bar system is connected with car body or bogie truck by a kind of suspension apparatus (or claiming protection suspension ring) by described protection sleeve, prevents accidental falling.There is following shortcoming:
After protection sleeve is first assembled with torsion bar shaft, then carry out the hot jacket assembling of other parts of torsion bar system, make troubles to the assembling of reverse arm, and be not easy to the operations such as the follow-up paint of torsion bar shaft, post-processing; Protection sleeve and torsion bar shaft free-running fit, without seal approach.During guideway vehicle carwash, water blast gun injection water may enter in protection sleeve, affects torsion bar shaft surface anti-corrosion effects.
Utility model content
The purpose of this utility model is to solve current anti-rolling torsion bar system when high-speed cruising train uses; the torsion bar shaft of sidewindering rigidity can be provided to provide protection for car body to generation torsional deflection, avoid being injured by a crashing object surface and reduction of service life by the sandstone splashed at a high speed.The inconvenience that follow-up reverse arm hot jacket assembling and paint operation are brought is given after solving installation of guard sleeve; Solve the sealing problem of protection sleeve and torsion bar shaft free-running fit.
A kind of anti-rolling torsion bar system torsion bar shaft fender guard; fender guard is arranged in anti-rolling torsion bar system torsion bar shaft; comprise pin thread and box; described fender guard is hollow cylinder body; opening part is provided with closing device; described closing device comprises pin thread and box, and described pin thread and box lock.
Further, fender guard is axially being provided with elastomer plastic along it.
Further, fender guard is provided with about its axisymmetric two groups of pin threads and box.
Further, pin thread and box are interference fit.
Further, torsion bar shaft fender guard material adopts PVC plastic, and PVC plastic is hyalomitome.
Anti-rolling torsion bar system adopts hot packaging technology, and surface need be painted, therefore torsion bar shaft fender guard could need be installed after paint drying, by operating the installation realizing torsion bar shaft fender guard as follows: take out torsion bar shaft fender guard, one hand-held pin end, one hand-held box end, firmly breaks into two with one's hands and makes fender guard encase torsion bar shaft, and now elastomer plastic will produce elastic deformation; Pin end is filled in box end, namely complete the installation of fender guard.
Taking out torsion bar shaft protecting sleeve, respectively from upper and lower to encasing anti-rolling torsion bar system torsion bar shaft, ensureing the box of the corresponding hypovalve of the pin thread of epivalve; Hold hypovalve on the other hand, another hand firmly down presses epivalve, makes the pin thread of epivalve enter the box of hypovalve, makes the box of epivalve encase the pin thread of hypovalve, namely completes the installation of protecting sleeve.
Beneficial effect:
1, the finishing operation being installed as anti-rolling torsion bar system of torsion bar shaft fender guard, the hot jacket not affecting torsion bar shaft and reverse arm is assembled, the paint on torsion bar shaft surface and post-processing;
2, torsion bar shaft fender guard two end section and reverse arm plane contact with each other, and smear sealant after assembling at contact surface, can play effective sealing effect, prevent high pressure water jets from injecting fender guard.
3, torsion bar shaft fender guard material adopts hard, transparent PVC plastics, and quality is light.The apparent order and condition that transparent design is convenient to follow-up anti-rolling torsion bar system torsion bar shaft is monitored, is followed the tracks of and review.
4, torsion bar shaft fender guard adopts one-piece construction, without other parts, is convenient to install, dismantle and management.
