Abstract

The invention relates to locomotive traction components, in particular to a pull rod device for locomotive traction. The pull rod device comprises a pull rod body, wherein the two ends of the pull rod body are respectively provided with a shaft hole, and a rubber joint is mounted in each shaft hole in a pressing mode. Each rubber joint comprises a central spindle and a rubber layer which is arranged on a middle shaft body of the central spindle in a vulcanized mode, wherein a washer is arranged on the end portion, corresponding to the rubber layer, of the central spindle, and the washer is tightly clamped on the central spindle through a snap spring check ring. The pull rod device achieves the function of bearing a locomotive body, reduces the impact force of the locomotive body at the same time, and is compact in structure, high in buffer energy, simple in structure and good in restoration capability.

Description

Locomotive traction pull rod device
Technical field
The present invention relates to locomotive traction parts, specifically a kind of locomotive traction pull rod device.
Background technology
Existing locomotive pull bar is generally a mono-block cast, and structure is single, and temperature conditions applicable during use is narrower, causes locomotive to move in specific region; During in addition due to locomotive operation, the more complicated and direction of power that pull bar bears differs, and causes pull bar to be greatly limited service life.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of locomotive traction pull rod device is provided, this pull rod device has not only met the function of bearing body but also can slow down vehicle body impulsive force simultaneously, and compact in architecture, and buffering energy is large, simple in structure, and reset capability is good.
According to technical scheme of the present invention: a kind of locomotive traction pull rod device, it is characterized in that: comprise drag link body, described drag link body two ends all offer axis hole, described in each, in axis hole, be respectively pressed with a rubber arthrosis, described rubber arthrosis comprises that mandrel and sulfuration are arranged at the rubber layer on the axis body of mandrel middle part, end corresponding to rubber layer on described mandrel arranges a packing ring, and described packing ring is clamped on mandrel by jump ring back-up ring.
As a further improvement on the present invention, described axis hole endoporus one end has radial protrusion portion, and the other end is opening end, when rubber arthrosis press-fits in described axis hole, rubber arthrosis upper end is resisted against on described lug boss, and rubber arthrosis lower end is provided with packing ring and jump ring back-up ring corresponding to the opening end place of axis hole.
As a further improvement on the present invention, axis hole outside is stretched out at described mandrel two ends.
Technique effect of the present invention is: pull bar of the present invention in use, can adapt to following service conditions: (1) longitudinally goes up, and the starting tractive effort that pull bar assembling can be subject to is-57.7KN~+ 51.7KN.(2) displacement that transversely, pull bar assembling one end mandrel can reach with respect to other end axle is-18mm~+ 18mm.(3) vertical upper, the displacement that pull bar assembling one end mandrel can reach with respect to other end mandrel is-45mm~+ 45mm.In the vertical, the impact load that pull bar assembling can bear is 106.6KN.This structure has not only met the function of bearing body but also can slow down vehicle body impulsive force simultaneously, and compact conformation, and buffering energy is large, simple in structure, and reset capability is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the partial enlarged drawing at I place in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, comprise mandrel 1, drag link body 2, packing ring 3, jump ring back-up ring 4, rubber layer 5, rubber arthrosis 6, axis hole 7, lug boss 8 etc.
As shown in Figure 1, a kind of locomotive traction pull rod device of the present invention, comprise drag link body 2, described drag link body 2 two ends all offer axis hole 7, described in each, in axis hole 7, be respectively pressed with a rubber arthrosis 6, described rubber arthrosis 6 comprises that mandrel 1 and sulfuration are arranged at the rubber layer 5 on mandrel 1 middle part axis body, and the end corresponding to rubber layer 5 on described mandrel 1 arranges a packing ring 3, and described packing ring 3 is clamped on mandrel 1 by jump ring back-up ring 4.
Described axis hole 7 endoporus one end have radial protrusion portion 8, the other end is opening end, when rubber arthrosis 6 press-fits in described axis hole 7, rubber arthrosis 6 upper ends are resisted against on described lug boss 8, and rubber arthrosis 6 lower ends are provided with packing ring 3 and jump ring back-up ring 4 corresponding to the opening end place of axis hole 7.
Axis hole outside is stretched out at described mandrel 1 two ends.
The present invention carries out one of critical component of locomotive traction, mainly play transmitting tractive power (braking force), transmit the effect of a part of transverse force simultaneously, the rubber arthrosis at pull bar assembling two ends, required every rigidity is provided, in locomotive operation process, allow that rubber in rubber arthrosis reverses, extruding, and under the working load condition of regulation, there is the service life that surpasses 5 years or 1,000,000 kilometers.
The present invention relates to one of critical component of locomotive traction, for carrying out locomotive traction.Drag link body 2 in the present invention, mandrel 1, packing ring 3, jump ring back-up ring 4 are metal material.Drag link body 2 connects the rubber arthrosis 6 at two ends, and rubber arthrosis 6 is formed by mandrel 1 and rubber layer 5 sulfurations, and rubber arthrosis 6 is pressed into drag link body 2 by being pressed into fixture after having plated zinc, then puts into packing ring 3, and firm with jump ring back-up ring 4 cards.This product is with bolts with framework and journal box body interface in use.This structure has not only met the function of bearing body but also can slow down vehicle body impulsive force simultaneously, and compact conformation, and buffering energy is large, simple in structure, and reset capability is good.
