Restriction.
Under a kind of car, the longitudinal direction between suspension member couples vibration absorber, includes two longitudinal directions in " several " font and couples
Damping element, longitudinally couple damping element connect back-to-back fixing after in " X " formula structure.Longitudinally couple damping element two ends and
Middle part is equipped with through hole.Two middle parts longitudinally coupling damping element and both sides are provided with longitudinal damping element 13, longitudinal damping unit
The inside of part 13 is provided with through hole.Bolt II9 penetrates the through hole on the left of longitudinal damping element 13, through longitudinally coupling damping element
Middle through-hole, pass the through hole on the right side of longitudinal damping element 13, and fastened by nut II.
Longitudinally couple the both sides of vibration absorber and be connected under car suspension member II2 under suspension member I1 and car, connect
Mode is that bolt connects.The arrangement longitudinally coupling vibration absorber is left and right centrosymmetry.Longitudinal damping element 13 is by three
Being grouped into, the material of longitudinal damping element 13 is the gum elastic element in cone or rounded steel spring.Longitudinal damping
The plane of two mounting seats of the longitudinally connected mounting seat 8 of element 13 is positioned at approximately the same plane.Longitudinally couple the material of damping element
Material is stainless steel material.
The know-why of the technical solution of the utility model is: suspension member under two adjacent lower suspension member I1 and car
The mounting seat of longitudinal damping element 13, longitudinal damping are installed by fastening bolt on the casing plane the latter half of II2 respectively
Element 13 mounting seat presents " several " word shape, and the one side that mounting seat protrudes is the installed surface of longitudinal damping element 13, and remaining is two years old
Individual work surface cooperates with the casing of suspension member II2 under lower suspension member I1 and car, is fastened by bolt I4 and nut I5
On casing.Each suspension member has two about longitudinally asymmetric longitudinally connected seat 8, the longitudinal damping unit between suspension member
Part 13 is arranged between two longitudinally connected seats 8 of homonymy, is penetrated from the middle part of longitudinal damping element 13 by check bolt 9,
Bolt 9 other end is locked by clamp nut II10, so, achieves two symmetries and indulge under adjacent car between suspension member
To the installation of damping element.
The effect using rubber spring or steel spring of longitudinal damping element 13 is better than hydraulic buffer, and longitudinally subtracts
Under parameter of shaking and vehicle traction braking acceleration, car suspension member with under the hang of car body, car suspension member quality and
Installation sites etc. are closely related, are required for suspension member under concrete car when design and carry out computational analysis, in order to full
Foot car under suspension member in the same direction with longitudinal damping demand during adverse movement, longitudinal damping element 13 be divide into three parts.This
Outward, owing to longitudinal damping element 13 is connected and fixed by fastening bolt II9, under need not dismounting car in the case of suspension member
Just can realize longitudinally coupling the installation of vibration absorber, whole installation process is convenient and swift, it is not necessary to individually workbench or
Special tool(s) just can complete to install.
1-4 and detailed description of the invention, be explained in further detail this utility model below in conjunction with the accompanying drawings.
As it is shown in figure 1, under two cars under suspension member I1 and car between suspension member II2 by longitudinally coupling vibration absorber
3 are linked together, and this longitudinal direction couples vibration absorber 3 and is arranged under car the casing of suspension member II2 under suspension member I1 and car
The latter half, it is to avoid the suspension on suspension member with car body produces impact, and longitudinal damping effect can be more preferably.
As in figure 2 it is shown, under suspension member I1 and car, longitudinal direction between suspension member II2 couples the number of vibration absorber 3 under car
Amount is two sets, and the arrangement longitudinally coupling vibration absorber 3 is symmetrical, suspension member uniform force under such car；Additionally,
Longitudinally the installation site of connection vibration absorber 3 is near outside, and effectiveness in vibration suppression can be more preferably.

Fixing is by bolt and nut clamp device, includes bolt II9, nut II10, plain washer II11 and spring washer II12.Should
Longitudinal damping element 13 be a kind of middle part be the damping element of through hole, can be cone gum elastic element, or circle
The steel spring of shape, is penetrated by bolt II9 on the convex surface being arranged on longitudinally connected mounting seat 8, and longitudinal damping element 13 is by three
It is grouped into so that under car, suspension member all plays damping effect in the same direction with adverse movement；Other the two of longitudinally connected mounting seat 8
Individual plane is arranged on car by including the bolt clamp device locking of bolt I4, nut I5, plain washer I6 and spring washer I7
On lower suspension member, it is anti-for being fastened under car two longitudinally connected mounting seats 8 on suspension member II2 under suspension member I1 and car
To install, thus can be implemented in and under car, between suspension member, set up the purpose longitudinally coupling vibration absorber, reached car
The effect of lower suspension member longitudinal damping.
As shown in Figure 4, the erection sequence of these device parts is: first, and longitudinally connected seat 8 is passed through bolt locking device
It is arranged under car on suspension member I1；Then, bolt 9 is used to penetrate the longitudinally connected seat of another one 8 and longitudinal damping element 13
Three parts so that longitudinally connected seat 8 and longitudinal damping element 13 position；Subsequently, longitudinally connected seat 8 is fixed under car suspention
On parts 2；Finally, use the lateral vibration absorbing element 13 that is locked such as nut II11, plain washer II12 and spring washer II13, complete
Become installment work.
