Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment:

the utility model provides a freight train sectional type sub vehicle frame, including longeron 1, longeron 1 is provided with two, connecting block 3 is all installed to the opposite side of 1 relative direction of two longerons, longeron 1 sets up to "L" shape, and outer wall fixed connection on the outer wall on the vertical face passes through second dead lever 6 and the horizontal plane, can make the horizontal part of longeron 1 and the vertical part of longeron 1 constitute a right angled triangle, because triangle-shaped has stability, consequently, can make the horizontal part and the more firm of vertical part of longeron 1, avoid when the car travels, the horizontal part of longeron 1 can be extruded to the longitudinal force of production, thereby lead to the atress of horizontal part great, long-term use back, can lead to 1 horizontal part of longeron to take place to buckle, cause the problem that whole sub vehicle frame damaged, the.

First spout 2 has been seted up to the inner wall of longeron 1, the equal fixed mounting in upper end of longeron 1 has backup pad 4, backup pad 4 is close to 1 one side of longeron and passes through first dead lever 5 and the one end fixed connection of longeron 1, can be when the car is fallen down, from the top when producing a decurrent longitudinal force, can play the guard action to the upper end of 1 transverse part of longeron, avoid when the car goes, the transverse part of longeron 1 can be extruded to the longitudinal force of production, thereby the atress that leads to transverse part is great, long-term use back, can lead to 1 transverse part of longeron to take place to buckle, cause the problem that whole sub vehicle frame damaged, the service life of device has been improved.

The inner wall of the first sliding chute 2 is inlaid with a cross beam 7, two ends of the cross beam 7 are set to be arc-shaped, two ends of the cross beam 7 are embedded into the inner wall of the arc-shaped chute 8, the arc-shaped chute 8 is arranged at a transverse corner of the first sliding chute 2, the problem that the auxiliary frame fails due to the fact that the cross beam 7 is separated from the inner wall of the first sliding chute 2 in the using process can be solved, the stability of the device is improved, the upper end and the lower end of the longitudinal beam 1 are attached to rubber cushions 9, the rubber cushions 9 are made of natural rubber, the rubber cushions 9 are embedded into the inner wall of the second sliding chute 10, the width of the second sliding chute 10 is equal to that of the cross beam 7, the notch of the second sliding chute 10 is set to be in a shape which the transverse side is opened, when extrusion force is applied to the cross beam 7, the cross beam 7 is prevented from impacting the outer wall of the second sliding chute 10, the, the stability of the device is improved and the second sliding grooves 10 are formed in the front and rear side walls of the first sliding groove 2.

Fixed block 11 is fixed to the front end of rubber cushion 9, the equal fixed mounting of one end of keeping away from longeron 1 of fixed block 11 has fixed plate 13, set up threaded hole 14 on fixed plate 13, the inner wall of threaded hole 14 is inlayed and is had screw 15, fixed plate 13 passes through screw 15 and longeron 1's inner wall fixed connection, can be after long-term the use, because rubber cushion 9 is extruded for a long time, lead to the elasticity of rubber cushion 9 to reduce, during the inner wall of the first spout 2 of protection that can not be fine, can dismantle rubber cushion 9, change rubber cushion 9, thereby the expense of maintenance has been reduced, fixed block 11 passes third spout 12 and extends to the outside of longeron 1 front end, the front end at second spout 10 is seted up to third spout 12.

The working principle is as follows: when the automobile goes, a longitudinal force can be exerted to the automobile, the longitudinal force can be acted on the lower end of the cross beam 7, thereby make the cross beam 7 under the effect of longitudinal force, can produce a relative effort, extrude the inner wall of first spout 2, this effort will make the cross beam 7 extrude rubber cushion 9, thereby make rubber cushion 9 shrink, thereby avoided the cross beam 7 direct with first spout 2 to act on the inner wall of first spout 2, thereby lead to first spout 2 to produce wearing and tearing, the effort still can extrude the horizontal part of longeron 1 simultaneously, the extrusion force transmits the vertical part of longeron 1 through second dead lever 6, thereby eliminate longitudinal force, avoid longitudinal force to extrude the horizontal part of longeron 1, lead to the horizontal part of longeron 1 to be crooked, cause longeron 1 to damage.

After using for a long time, because crossbeam 7 extrudees rubber cushion 9, make the elasticity of rubber cushion 9 can reduce gradually, thereby lead to rubber cushion 9 not to play the effect of protection, can be with the help of the screwdriver this moment, rotate screw 15, make screw 15 break away from the inner wall of screw hole 14, thereby make fixed plate 13 break away from the inner wall of longeron 1, then stimulate fixed plate 13, make fixed plate 13 drive fixed block 11 and slide at the inner wall of third spout 12, fixed block 11 slides and drives rubber cushion 9 and slide at the inner wall of second spout 10, thereby dismantle rubber cushion 9, change, then repeat the inner wall of above-mentioned operation with rubber cushion 9 refastening to second spout 10.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
