The utility model provides a not enough to prior art, the utility model provides a freight train shock absorber that seam welding sealed solves among the prior art automobile shock absorber and bears the shock attenuation because of the extreme production driver's cabin beat or packing box beat of road conditions in the automobile driving process and can not bear great pulling force and the problem that became invalid.
In order to improve the deficiency in the above-mentioned background art, the utility model discloses a following technical scheme realizes:
a seam-welded seal freight car shock absorber, comprising:
the vibration damping device comprises a vibration damping body, a vibration damping device and a control device, wherein the vibration damping body comprises a vibration damping outer cylinder and a working cylinder, the vibration damping outer cylinder is arranged outside the working cylinder, and the working cylinder is of a hollow cylindrical structure;
the connecting rod is arranged inside the working cylinder;
the guide device is assembled and connected on the connecting rod; one end of the guider is arranged at the top end of the working cylinder, and the other end of the guider is connected with the oil seal body;
the oil seal spring is arranged on the guider;
the oil seal body is connected with one end of the guider;
the oil seal cover is arranged on the oil seal body, and the edge end of the oil seal cover is arranged inside the vibration reduction outer barrel.
As a preferred embodiment of the present invention: and a certain space is arranged between the vibration reduction outer cylinder and the working cylinder.
As a preferred embodiment of the present invention: the connecting rod is arranged in a hollow structure in the working cylinder through a piston valve.
As a preferred embodiment of the present invention: the inside interference fit assembly of adoption of director is connected on the connecting rod.
As a preferred embodiment of the present invention: the upper end of the guider is connected with the oil seal body in a sealing and matching manner.
As a preferred embodiment of the present invention: the outer part of the guider is in sealing fit assembly with the working cylinder.
As a preferred embodiment of the present invention: the oil seal body is tightly assembled and connected with one end of the guider.
As a preferred embodiment of the present invention: the oil seal cover is covered on the oil seal body in a sealing mode, and the edge of the oil seal cover is fixed in the outer cylinder of the shock absorber in a seam welding mode.
The beneficial effects of the utility model reside in that:
the oil seal cover is added by changing the structure of the guider and the oil seal on the original structure of the shock absorber, and the sealing mode of seam welding and sealing is adopted between the oil seal cover and the outer cylinder of the shock absorber; the problem that the shock absorber fails due to the fact that the cab and the container of the truck deflect to generate large tensile force when the truck runs under the extreme road conditions is avoided, meanwhile, vibration of the truck body caused by the fact that the road surface is uneven is relieved, and the space of a steering system is saved.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
Referring to fig. 1, in a seam-welded and sealed shock absorber for a truck, a connecting rod 1 is arranged in a working cylinder 7 through a piston, and the piston is assembled with the inside of the working cylinder 7 in an interference fit manner and is assembled with the connecting rod 1 in an interference fit manner; the outer cylinder 5 of the shock absorber is arranged outside the working cylinder 7, a certain space gap is arranged between the outer cylinder 5 of the shock absorber and the working cylinder 7, and the working cylinder 7 is of a hollow cavity structure.
Referring to fig. 1, the guide 4 and the connecting rod 1 are assembled on the connecting rod by interference fit; one end of the guider 4 is embedded in the working cylinder 7 and is assembled with the inner wall of the working cylinder 7 in an interference fit manner; the other end of the guider 4 is in interference fit assembly connection with the oil seal body 2; be equipped with oil blanket spring 6 on director 4, oil blanket spring 6 plays the effect of supporting director 4 and oil blanket body 2.
Referring to fig. 1, one end of the oil seal body 2 is connected with the guider 4 in a sealing assembly mode, the other end of the oil seal body is covered by the oil seal cover 3 in a sealing mode, the edge portion of the oil seal cover 3 is embedded into the outer cylinder 5 of the shock absorber, and the oil seal body is fixed with the outer cylinder 5 of the shock absorber in a sealing mode through seam welding.
