Abstract
The utility model discloses a lining structure which is characterized by comprising two fan-shaped outer pipes, an inner pipe arranged within two outer pipes, a rigid sheet arranged between the outer pipes and the inner pipe, and rubber arranged between the outer pipes, the rigid sheet and the inner pipe. The lining structure is long in service lifetime and reduces product degumming risk, and the thickness of the rigid sheet at two sides is adjusted to improve the single-direction static stiffness of the lining.
Description
Technical field
The utility model relates to a kind of bush structure, belongs to auto parts and components technical field of structures.
Background technique
Along with the development of automotive industry, it is mainly the debugging of sizing material, the change of product structure that automobile product has more and more higher requirement, traditional debug performance to the fatigue of lining, performance etc.The outer tube of conventional bushings is cylindrical shape, and product need tighten, and just can have the effect that tightens that tightens lining.When product is subject to tightening power, the amount of tightening is excessive, can increase the risk of coming unstuck of product, and cannot adjust the quiet ratio of rigidity of products radial both direction, does not meet the larger requirement of certain party radius vector rigidity requirement value.
Summary of the invention
The technical problems to be solved in the utility model is: the bush structure that a kind of simple in structure, easy processing is provided, solved the radially tired requirement of lining harsher, and radially the quiet rigidity of both direction is inconsistent, and by sizing material, debug the problem that cannot meet customer requirement.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of bush structure, it is characterized in that, the outer tube that comprises two sector structures, the centre of two outer tubes is provided with inner tube, is provided with rigidity sheet between outer tube and inner tube, between outer tube, rigidity sheet and inner tube, is equipped with rubber.
Preferably, the respectively corresponding two rigidity sheets of two described outer tubes.
Preferably, between two gaps between two described outer tubes, be equipped with Yi Ge rubber buffer mechanism.
Preferably, described rubber buffer mechanism is provided with a hole, and it is shaped as " two hands are to pop-up " shape, and faces inner tube.
Preferably, described pitch-row is recess from inner tube on the one end away from.
Preferably, described outer tube is provided with guiding chamfering.
Between each part of the present utility model, there is adhesive bonding, can be because of after each part multiple-contact of product, thus cause rubber damaged and come off, working life is long.
The utility model changes conventional bushings cylindrical outer tube as two sector structures into, and when product is subject to tightening power, the amount of tightening is little, and can not increase the risk of coming unstuck of product.Increased in the middle two rigidity sheets, due to lining, radially the quiet stiffness ratio of two directions is different, by adjusting the thickness of rigidity sheet, can adjust the quiet ratio of rigidity of products radial both direction.The direction that press-fits at each outer tube two ends has increased a guiding chamfering simultaneously, prevents that product from misplacing when press-fiting, and causes outer tube compressive strain.Owing to having increased a damping mechanism, can play the effect of a buffering, when avoiding both sides outer tube to contact, produce abnormal sound in fatigue process.

Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The utility model is a kind of bush structure, as shown in Figure 1 and Figure 2, is a kind of structural representation of bush structure.It comprises the outer tube 1 of two sector structures, the centre of two outer tubes 1 is provided with inner tube 4, between outer tube 1 and inner tube 4, rigidity sheet 3 is installed, form one and increase rigidity mechanism, and two outer tubes 1 are corresponding one by one with two rigidity sheets 3 respectively, between outer tube 1, rigidity sheet 3 and inner tube 4, all by rubber 2, be connected.
Two outer tubes 1 sulfide with rubber 2 respectively, and have increased a guiding chamfering 7 (as shown in Figure 4) in the direction that press-fits of outer tube 1, form a guide mechanism.Rubber 2 sulfides with rigidity sheet 3, between two gaps between two outer tubes 1, is equipped with Yi Ge rubber buffer mechanism 5.In rubber buffer mechanism 5, have a hole 6, it is shaped as " two hands are to pop-up " shape, and faces inner tube 4.Hole 6 is apart from being recess A on inner tube 4 one end far away.
Between each part of the present utility model, there is adhesive bonding, can be because of after each part multiple-contact of product, thus cause rubber damaged and come off, working life is long.Outer tube 1 adopts two sector structures, and when product is subject to radially tightening power, rubber 2 can reduce stress, and can not increase the risk of coming unstuck of product.
The utility model changes conventional bushings cylindrical outer tube as two sector structures into, two rigidity sheets 3 have been increased in the middle, due to lining, radially the quiet stiffness ratio of two directions is different, by adjusting the thickness of rigidity sheet 3, can adjust the quiet ratio of rigidity of products radial both direction.The direction that press-fits at each outer tube 1 has increased a guiding chamfering 7 simultaneously, prevents that product from misplacing when press-fiting, and causes outer tube 1 compressive strain.
The utility model in press-fiting process, owing to being subject to the effect of a contractile force, slowly close of two outer tubes 1, this process is equivalent to the process that tightens of conventional bushings, and can, because the amount of tightening is excessive, not cause product to come unstuck.When being press fit into mounting ring, as shown in Figure 3, the outer tube 1 on both sides pushes to centre, the rubber of recess A both sides gap gradually diminishes, the rubber of high spot B swells gradually, can play the effect of a buffering, the abnormal sound of avoiding both sides outer tube 1 to produce in the process of contact.
The utility model is placed on quiet rigidity tester, inner tube 4 is when being subject to radial loaded power, inner tube 4 is first close to outer tube 1 together with rigidity sheet 3, owing to having increased rigidity sheet 3, be equivalent to increase the effective area of contact of rubber 2 of this direction, this direction ratio of rigidity of product does not increase the rigidity of rigidity sheet 3 directions and wants large.
The utility model is placed in press-loading device, and product outer tube 1 two ends have increased a guiding chamfering 7, and product is in press-fiting, and the chamfering that led before this 7 enters in mounting ring, has effectively prevented product mistake when press-fiting, and causes the compressive strain of product outer tube.
The utility model is placed in fatigue testing machine, product is because the interference press-fiting is larger, product press-fit the process that tightens that is just equivalent to product, product is when press-fiting, the stress that rubber is 2 can effectively be eliminated, and does not have the risk of coming unstuck, and product is when the harsher fatigue condition of the condition that is subject to, owing to having increased a damping mechanism (as shown in Figure 3), can prevent product in fatigue process, to produce abnormal sound.
