Description
Technical field
The utility model relates to a kind of lining, and in particular, the utility model relates to a kind of angle adjustable insert for regulating automobile suspension system.
Background technique
Dynamic assembly suspension be on car load with the tight component of NVH, it is the support of whole power assembly, be used for isolating the major part vibration of power assembly to vehicle body, and controlling vehicle power assembly when accelerating, slow down, crossing bank and jolting the road surface and rocking in engine compartment, directly affecting the travelling comfort of vehicle drive.
In the vehicle R﹠D process, the debugging of lower tie-rod is a very important link, and its quality is on the NVH performance of car load and drive sense conclusive impact is arranged.Rigidity is the most important index of lower tie-rod lining, and the size of rigidity depends on the structure of lower tie-rod master spring and the material of rubber, and existing debugging is usually changed by its rubber material and realizes with the stiffness variation that suspends.
In the existing debug process that suspends, after being generally suspending of trial assembly different-stiffness and doing objective evaluation, just make rigidity and select, if the improper redistribution sizing material that also needs is made part again, dismounting assembling again, whole process wastes time and energy.All there is certain intervals in the rigidity numerical value of lower tie-rod in order to debugging, and discontinuous, Optimal Stiffness numerical value might just exist in this interval, is not optimum thereby cause the rigidity value of final locking with regard to that point that has probably missed best rigidity in debug process like this.
Mentioned a kind of stiffness variable suspending apparatus in patent documentation CN201120023909.0, comprise two groups of front-suspensions, each is organized front-suspension and includes the main spring that an assembling is located at the longitudinal beam bottom, be articulated in connecting rod and the damping shock absorber of longitudinal beam top airfoil, described main spring top contacts with described connecting rod, comprise that also two assemblings are located at the auxiliary spring of longitudinal beam top airfoil, described auxiliary spring is divided into the both sides of described connecting rod and longitudinal beam articulating point, and the top of described auxiliary spring and connecting rod are provided with the gap between the bottom.
This auxiliary spring comprises auxiliary spring and guidance set, and described auxiliary spring is sheathed on described guidance set, and the length of guidance set is less than the length of auxiliary spring.
In the less situation of operator cabin load, the main spring that length increases can independent role, realizes little rigidity requirement.When large or operator cabin was excessive with respect to the vertical vibration displacement of vehicle frame when operator cabin load, main spring and auxiliary spring acted on simultaneously, thereby realize adaptively changing rigidity, and it both can increase bearing capacity, also can change the operator cabin resonant frequency, effectively reduced and vibrated.
In this patent documentation, the adjusting of rigidity is that the length by main spring and/or auxiliary spring decides, and obvious adjustable range in stiffness is little, and underaction.

Embodiment
Describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing, identical reference number represents identical element in the accompanying drawings.
With reference to figure 1, variable lining of the present utility model comprises jacket wall 3, main shaft 4, the first main spring 21 and the second main spring 22, the first axle sleeves 5 and the second axle sleeve 8, and clamp holder 9.The first axle sleeve 5 and the second axle sleeve 8 are set on main shaft 4, and preferably, the first axle sleeve 5 and the second axle sleeve 8 can rotate freely with translation-angle around main shaft 4.The first end sulfuration of the first main spring 21 is on the first axle sleeve 5, and the second end sulfuration relative with its first end of the first main spring 21 is on slide plate.The first end sulfuration of the second main spring 22 is on the second axle sleeve 8, and the second end sulfuration relative with its first end of the second main spring 22 is on slide plate.Slide plate is arranged in jacket wall 3 and can be along with the first main spring 21 and the second main spring 22 translation-angles and in the interior slip of jacket wall 3.Clamp holder 9 can be adjusted in and is arranged on jacket wall 3 and slide plate 7 can be clamped on jacket wall 3.
