CN204322969U is disclosed " automobile damping spring improved structure ", including being positioned at the longeron in underbody portion, axletree and base plate, and damping spring, axletree is set with sliding sleeve, the guide rail of anti-rotation is set between sliding sleeve and axletree, being provided with spring base on the upside of sliding sleeve, the lower end of described damping spring is arranged in spring base；Described connecting plate side being provided with bearing, being connected by bearing pin between this bearing with spring base has push-pull bar simultaneously.Quadric chain is formed between push-pull bar and the axletree of this documents, so that it is guaranteed that push-pull bar is the most parallel with axletree, when axletree is swung up, push-pull bar can promote sliding sleeve distally to move, so that it is guaranteed that lower spring end distally moves, thus can ensure that the stress of spring is always pivot pin stress, spring maximum performance can be played.Spring damaging is greatly reduced by the structure owing to being designed with, such that it is able to reduce the performance standard of spring, reduces production cost.This reasonable in design, using effect is good, is suitable for promotion and implementation.The problem that this application is solved with the application is identical, but structurally has the difference of essence.
Summary of the invention
It is an object of the invention to provide shock-absorbing spring and the attachment structure of car body side bar after a kind of automobile, it can reduce shock-absorbing spring deformation and the risk damaged, and increases the service life of shock-absorbing spring；The compression campaign of shock-absorbing spring can be played position-limiting action, prevent automobile when uneven road surface travels, shock-absorbing spring and spring pad offset and come off；Meanwhile, good damping result, quality be little, low cost, connection are reliable.
Shock-absorbing spring and the attachment structure of car body side bar after a kind of automobile of the present invention, including car body side bar, it is connected to the spring seat of honour below described car body side bar, shock-absorbing spring, it is characterized in that: also include the spring pad being located between the described spring seat of honour and shock-absorbing spring；Described spring pad is provided with Access Division, the upper end of described shock-absorbing spring and the clamping of described Access Division.
Further, described spring seat of honour entirety is in the form of annular discs, and its edge is provided with flange, and centre is provided with location division.
Further, described spring pad entirety is in the form of annular discs, and centre is provided with a circular groove；Location division on the described spring seat of honour is corresponding with the circular groove on described spring pad/contacts.
Further, four times to five times of the height that external diameter is described flange at the described spring seat of honour.
Further, the upper surface at the described spring seat of honour is vertical with described flange.
Further, the upper surface of described spring pad is radially even is provided with bar-shaped trough.
Further, the upper surface at the described spring seat of honour and described car body side bar welding.
The technique effect that the present invention is useful:
Owing to the spring seat of honour is connected with car body side bar, the upper end of shock-absorbing spring is connected with spring pad, spring pad and spring seat of honour corresponding matching so that shock-absorbing spring and spring are lined with free gap, reduce shock-absorbing spring and deform the risk even damaged, add the service life of shock-absorbing spring；Due to the spring seat of honour be provided with location division, spring pad is provided with circular groove, location division is corresponding with circular groove, it is therefore prevented that automobile when uneven road surface travels, shock-absorbing spring and spring pad skew and the phenomenon that comes off；Meanwhile, good damping result, quality be little, low cost, connection are reliable.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the present invention is elaborated.
Seeing Fig. 1 or Fig. 2, after a kind of automobile, shock-absorbing spring and the attachment structure of car body side bar, including car body side bar 1, be connected to the spring seat of honour 2 below described car body side bar 1, shock-absorbing spring 3, and its prominent substantive distinguishing features is:
Also include the spring pad 4 being located between the described spring seat of honour 2 and shock-absorbing spring 3；Described spring pad 4 is provided with Access Division 41, the upper end of described shock-absorbing spring 3 and described Access Division 41 clamping.Owing to the spring seat of honour 2 is connected with car body side bar 1, the upper end of shock-absorbing spring 3 is connected with spring pad 4, spring pad 4 and the spring seat of honour 2 corresponding matching so that shock-absorbing spring 3 and spring pad 4 have free gap, shock-absorbing spring 3 can be reduced and deform the risk even damaged, increase the service life of shock-absorbing spring.
Seeing Fig. 3 or Fig. 4, the described spring seat of honour 2 is overall in the form of annular discs, and its edge is provided with flange 21, and centre is provided with the projection that location division 22(is in Fig. 3).
Seeing Fig. 5, described spring pad 4 is overall in the form of annular discs, and centre is provided with a circular groove 42；Location division 22 on the described spring seat of honour 2 is corresponding with the circular groove 42 on described spring pad 4/contacts.The spring seat of honour 2 and the design of spring pad 4 structure, it is possible to the compression campaign to shock-absorbing spring 3 plays position-limiting action, it is ensured that the motion of shock-absorbing spring 3 in the vertical direction, and shift phenomenon does not occur.The upper surface of spring pad 4 and the spring seat of honour 2 act primarily as the effect of the power of withstanding shocks, and flange 21 ensure that automobile spring pad 4 and shock-absorbing spring 3 when uneven road surface travels do not fall off.
See Fig. 3 or Fig. 4, it is characterized in that: the external diameter at the described spring seat of honour 2 is four times to five times of the height of described flange 21.The external diameter at the spring seat of honour 2 limits with the ratio of the height stating flange 21, it is possible to effectively alleviate the phenomenon of the spring seat of honour 2 cracking, increases the service life at the spring seat of honour 2.
The upper surface at the described spring seat of honour 2 is vertical with described flange 21.By the upper surface at the spring seat of honour 2 and flange 21 vertical design, it is possible to preferably make spring pad 4 fit with the spring seat of honour 2, prevent automobile when uneven road surface travels, the phenomenon that spring pad 4 and shock-absorbing spring 3 come off occurs.
The upper surface of described spring pad 4 is radially even is provided with bar-shaped trough 43.Bar-shaped trough 43 can alleviate the weight of spring pad 4, can increase the rigidity of spring pad 4 simultaneously and play good damping effect.
The upper surface at the described spring seat of honour 2 is connected for spot welding with described car body side bar 1.
The present invention can reduce shock-absorbing spring deformation and the risk damaged, and increases the service life of shock-absorbing spring；The compression campaign of shock-absorbing spring can be played position-limiting action, prevent automobile when uneven road surface travels, shock-absorbing spring and spring pad offset and come off；Meanwhile, good damping result, quality be little, low cost, connection are reliable.
