Technical Field

The present invention relates to a vehicle vibration damping member, and more particularly, to a lateral stopper having high stability.

Background

The rubber stopper is a commonly used rubber-metal composite vibration damping limiting element, can be widely applied to various vibration damping limiting places, and is particularly widely applied to a bogie of a locomotive vehicle.

When railway vehicles such as subways run on underground, ground and overhead lines, the vehicles are easy to transversely move due to construction line factors and often pass through small curve radiuses, and in order to avoid dangerous working conditions such as vehicle rollover and the like, transverse stopping structures are arranged on bogies, are arranged on the inner sides of bogie frame frames, limit the transverse displacement of the vehicle body, mainly bear transverse loads, alleviate transverse rigid impact and improve the transverse vibration performance of the vehicle body.

One end of the transverse stop is a bottom plate which is fixed with the bogie, the other end of the transverse stop is provided with a wear-resisting plate which is in contact with the vehicle body, a rubber part is arranged between the bottom plate and the wear-resisting plate, and the rubber part is a member formed by vulcanizing rubber and metal. The wear-resisting plate and the rubber part are integrated through vulcanization, when the vehicle moves transversely, the wear-resisting plate is in contact with a vehicle body to bear pressure, and the wear-resisting plate and the rubber part are bonded into a whole through vulcanization and are easy to fall off; the bottom plate is fixed with the bogie through the fastener, and the fastener has not hard up risk, therefore, antifriction plate and bottom plate have played the key effect to the stability of horizontal backstop in operating mode.

Disclosure of Invention

The invention aims to solve the technical problem of providing a transverse stop with higher stability aiming at the stress condition of a wear-resisting plate and a bottom plate in the actual working condition.

The utility model provides a horizontal backstop with higher stability, be provided with the boss that has the same material with the antifriction plate on the antifriction plate of horizontal backstop, boss and antifriction plate are as an organic whole, and the boss stretches into rubber portion, through vulcanizing and the rubber portion integrated into one piece of horizontal backstop to increase the area of contact of antifriction plate and rubber portion.

The boss and the wear-resisting plate are integrated and extend into the rubber part, and the additional arrangement of the boss is equivalent to increase of the vulcanization area of the wear-resisting plate and the rubber part, so that the bonding strength of the wear-resisting plate is improved, and the problem that the wear-resisting plate is easy to fall off is solved.

Furthermore, a bottom plate of the transverse stop is fixed with the bogie through bolts and nuts, one side of at least one bolt is provided with a rotation stopping step with a straight line edge, and the rotation stopping step is positioned on the bottom plate; the bolt is a hexagon bolt or a square bolt, and one edge of the hexagon bolt or the square bolt is parallel to and close to the rotation stopping step.

One side of the bolt is parallel to the rotation stopping step and is close to the rotation stopping step, so that the bolt can be prevented from rotating, and the risk of loosening the bolt is well avoided.

Furthermore, a bottom plate of the transverse stop is fixed with the bogie through bolts and nuts, one side of at least one nut is provided with a rotation stopping step with a straight line edge, and the rotation stopping step is positioned below the bottom plate; the nut is a hexagonal nut or a quadrangular nut, and one edge of the hexagonal nut or the quadrangular nut is parallel to and close to the rotation stopping step.

In a similar way, the rotation stopping step is arranged below the bottom plate, the nut is positioned below the bottom plate, the nut is prevented from rotating, and the risk of loosening of the bolt can be avoided.

Furthermore, the fasteners are arranged on two sides of the bottom plate, and the shape of the rotation stopping step is matched with the shape of the end parts on two sides of the bottom plate. The rotation stopping steps cannot protrude from the two sides of the bottom plate, so that the installation space is occupied. The shape of the end parts at two sides is matched, so that the processing is convenient.

Further, the shape of the boss is a conical shape with a rounded bottom surface.

Furthermore, the radius difference between the bottom surface and the top surface of the boss is 3-4 mm.

The boss is skillfully arranged into the conical shape, the conical boss is equivalent to a hook for hooking the rubber, and the conical contact area is larger than that of the straight cylinder, so that the anti-falling performance of the wear-resisting plate is further improved.

Further, the diameter of the bottom surface of the boss is 25-40% of the width of the long edge of the wear-resisting plate. Too big too taken up too much rubber space of boss, can influence the performance of rubber backstop product, too little, the bonding strength is not enough, can not play the effect of anticreep.

Further, the thickness of the depth wear-resistant plate of the boss is 100% -120%.

Further, one end, far away from the boss, of the wear-resisting plate is provided with a chamfer. And a chamfer is arranged at one end far away from the boss to prevent the stop from shearing stress.

Furthermore, the angle of the chamfer is 3-7 degrees.

The invention has the following beneficial effects:

the invention relates to a transverse stop with high stability, which is characterized in that the stability of the transverse stop is improved by improving the structures of the connecting parts of the transverse stop, a vehicle body and a bogie, and particularly, the structure of a wear-resisting plate in contact with the vehicle body is improved, the wear-resisting plate has the defect of easy falling in an actual working condition because the wear-resisting plate and a rubber part are bonded together through vulcanization, the larger the contact area of the wear-resisting plate and the rubber part is, the larger the bonding strength is, so that under the condition of ensuring that the strength of the vulcanized part is not influenced, a boss is additionally arranged, the boss and the wear-resisting plate are integrated, the wear-resisting plate is made of the same material as the wear-resisting plate, the wear-resisting plate is substantially increased, the contact area of the wear-resisting plate and the rubber part is increased, the bonding strength is well enhanced, and the anti-falling effect is achieved. The structure of the bottom plate connected with the bogie is improved, the bottom plate is connected with the bogie through the fastening piece, the vibration is large in the vehicle running process, the vibration duration is long, the fastening piece has the risk of loosening, and in order to avoid the loosening of the fastening piece, the nut or the bolt needs to be prevented from rotating.

According to the invention, under the condition of considering not influencing the stopping performance of the rubber, the structures of the wear-resisting plate and the bottom plate of the rubber stopper are improved, the problems that the wear-resisting plate is easy to fall off and the fastening piece of the bottom plate is easy to loosen are solved, and the use stability of the transverse stopper in the actual working condition is improved.
