Abstract

The utility model relates to the technical field of the connecting piece of a vehicle, in particular to a bush of an auxiliary frame of a car, which is provided with an adjustable vibration-damping block, is rigid and prevents axial displacement. The bush of the auxiliary frame of the car comprises an inner pipe, a vibration-damping block and an outer pipe, wherein the inner pipe, the vibration-damping block and the outer pipe are sequentially bonded, and the outer side of the inner pipe is provided with a convex ring 1; the inner side of the vibration-damping block is provided with an annular recess 1 matched with the convex ring 1 at the outer side of the inner pipe, and the outer side of the vibration-damping block is provided with a convex ring 2; and the inner side of the outer pipe is provided with an annular recess 2 matched with the convex ring 2 at the outer side of the vibration-damping block. The convex blocks or the recesses are respectively arranged among the inner pipe, the vibration-damping block and the outer pipe, and the axial displacement of an elastic block is prevented after the inner pipe, the vibration-damping block and the outer pipe are bonded. A clearance is arranged between the inner side of the outer pipe and the outer side of the vibration-damping block, and the convex ring 2 of the vibration-damping block is provided with an arc-shaped recess at the end face of the position of the clearance. The rigidity of the vibration-damping block is adjusted by adjusting different depth of the arc-shaped recess, which adapts to different requirements.

Description

The secondary car frame lining
Technical field
The utility model relates to vehicle link technical field, especially the secondary car frame lining of the anti-axial displacement of damping block adjustable rigid.
Background technique
Secondary car frame is the link between propons and motor, is again the forward mounting fulcrum, be alleviate front of the car travel in the vibration key component, reduce the vibration that is delivered to vehicle body so subframe and vehicle body joint need increase lining.Patent No. ZL200820157677.6 discloses a kind of secondary car frame; Subframe is provided with four mounting holes for four jiaos, is embedded with metal lining in the mounting hole, and rubber damping is packaged in metal lining, and bolt passes the rubber damping piece subframe is fixed; Deficiency is: the rubber damping piece is easy to wear, thereby influences effectiveness in vibration suppression; Adopt a kind of improved secondary car frame lining at present, be fixedly connected sequentially and constitute by metal inner pipe, rubber damping piece, metal outer pipe, though the rubber damping piece of this subframe lining is not easy to wear, there is the easy axial displacement of rubber damping piece, the shortcoming that rubber damping piece rigidity can not be adjusted.
Summary of the invention
The purpose of this utility model is to overcome the existing easy axial displacement of secondary car frame lining rubber damping piece, and rubber damping piece vibration damping rigidity can not be adjusted the shortcoming of rigidity.
The purpose of this utility model is achieved through the following technical solutions:
The secondary car frame lining comprises interior pipe, damping block, outer tube, and is bonding successively between described interior pipe, damping block, outer tube, and it is characterized in that: the pipe outside is provided with bulge loop one in described; Described damping block inboard is provided with the ring-shaped depression one adaptive with interior pipe outside bulge loop one, and the described damping block outside is provided with bulge loop two; Described outer tube inboard is provided with the ring-shaped depression two adaptive with damping block outside bulge loop two.Described damping block material is a synthetic rubber; Have bulge loop or depression respectively between pipe, damping block, outer tube in described, can prevent damping block axial displacement after bonding.
As preferably: described outer tube inboard with damping block outside between have the gap: two of described damping block bulge loop two and outer tube ring-shaped depressions are bonding.
As preferably: described damping block bulge loop two is provided with arc-shaped recess at the gap location end face.Arc-shaped recess is set, and the rigidity that can regulate damping block by the different depth of adjusting arc-shaped recess adapts to different needs.
As preferably: pipe middle part in described secondary car frame lining, described bulge loop one are arranged on; Described ring-shaped depression one is arranged on the damping block middle part, described bulge loop two is arranged on the damping block middle part; Described ring-shaped depression two is arranged on the outer tube middle part; Described bulge loop two length are longer than bulge loop one.
As preferably: described secondary car frame lining, described damping block and interior pipe are isometric; Described outer length of tube is less than interior length of tube.
As preferably: described damping block material is a synthetic rubber, described in pipe, outer tube material be steel.
Bolt passes that pipe is connected with vehicle body in the secondary car frame lining, outer tube is connected with subframe; Damping block absorbs and has intercepted the vibration that motor produces and passes on the vehicle body, and the car vibration reduced.
The beneficial effect of this model utility is:
Be respectively equipped with projection or depression between pipe, damping block, outer tube in described, prevent damping block axial displacement after bonding.Have the gap between the outer tube inboard and the damping block outside, described damping block bulge loop two is provided with arc-shaped recess at the gap location end face, and the rigidity by the different depth of adjusting arc-shaped recess is regulated damping block adapts to different needs.
Description of drawings
Fig. 1 is a prior art secondary car frame lining schematic representation;
The schematic representation of Fig. 2 the utility model secondary car frame lining.
Embodiment
The utility model is as shown in Figure 2: interior pipe 1 is made for steel, and outer middle side part is provided with bulge loop 1; Damping block 2 materials are synthetic rubber, and middle inside is provided with the ring-shaped depression one 21 adaptive with interior pipe outside bulge loop one, and the outer middle side part of damping block is provided with bulge loop 2 22; Outer tube 3 is made for steel, and middle inside is provided with the ring-shaped depression two 31 adaptive with damping block outside bulge loop two; Have gap 32 between the outer tube inboard and the damping block outside: damping block projection two is provided with arc-shaped recess 23 at the gap location end face; Bulge loop two length are longer than bulge loop one; Damping block and interior pipe are isometric; Outer length of tube is less than interior length of tube.Binder is bonding between interior pipe and damping block, and two binders of damping block projection two and outer tube ring-shaped depression are bonding.
Be respectively equipped with projection or depression between interior pipe, damping block, outer tube, prevent elastomer block axial displacement after bonding.Have the gap between the outer tube inboard and the damping block outside, damping block bulge loop two is provided with arc-shaped recess at the gap location end face, and the rigidity by the different depth of adjusting arc-shaped recess is regulated damping block adapts to different needs.
Bolt passes that pipe is connected with vehicle body in the secondary car frame lining, outer tube is connected with subframe; Damping block absorbs and has intercepted the vibration that motor produces and passes on the vehicle body, and the car vibration reduced.
