Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The present embodiment is related to a kind of bush of swing arm, and the bush of swing arm mainly includes inner tube, rubber sleeve main body and outer tube, its
In, the installing of rubber sleeve main body fixed cover is put on inner pipe, and outer tube sleeve dress is arranged on rubber sleeve body exterior, at rubber sleeve main body
It is formed with hollow-out parts.
The bush of swing arm of the present embodiment, by the setting of hollow-out parts, to reduce the torsional rigidity of bush of swing arm radial direction,
Suspension can be made to possess preferable damping property, improve vehicle comfortableness；Can also reduce what external impact force was caused to bush of swing arm
Stress, and the durability of bush of swing arm can be improved, extend its service life.
Based on above design philosophy, a kind of example arrangement of the present embodiment is as shown in figure 1, for easy to process, hollow out
Portion 201 is arranged at the periphery of rubber sleeve main body 2, namely hollow-out parts 201 are formed between the inwall of outer tube 1 and the gabarit of rubber sleeve main body 2,
The bush of swing arm can be made has preferable damping property.Specifically, in the radial direction of inner tube 3 hollow-out parts 201 height H3, be rubber
The 2/9~4/9 of the set thickness of main body 2, optimal design is 1/3, and the length of the hollow-out parts 201 in the axial direction of inner tube 3 is about hollow-out parts
The twice of 201 height H3.The setting of the structure, can both reduce the radial direction torsional rigidity of this bush of swing arm, play damping effect,
The requirement of its radial rigidity can be met again.Certainly, the height H3 of hollow-out parts 201 is except that can be the 2/9~4/ of the thickness of rubber sleeve main body 2
9, it can also be more than the 4/9 of the thickness of rubber sleeve main body 2 certainly, or less than the 2/9 of the thickness of rubber sleeve main body 2, simply when it is more than
The thickness of rubber sleeve main body 2 4/9 when, this bush of swing arm radial rigidity can be made to be deteriorated, and work as it and be less than the thickness of rubber sleeve main body 2
When 2/9, radial direction torsional rigidity reduction scope is smaller, it is difficult to play damping effect.
Additionally, the longitudinal section of hollow-out parts 201 is trapezoidal, and trapezoidal each edge is equipped with fillet, to ensure rubber sleeve
The structural strength of main body 2.Except that can be fillet, it can also be angle for trapezoidal each corner, and simply horn structure is long-term bears outer
Power impact is fragile.In addition, the quantity of hollow-out parts 201 is along axially arranged two of rubber sleeve main body 2, its except that can be two,
Can be also one, three or other quantity, can specifically be determined according to this bush of swing arm length.
In the present embodiment, at the two ends of rubber sleeve main body 2, it is fixed with and extend to outer tube 1 to be wrapped in the limit of the end of outer tube 1
Position portion 202.When limiting section 202 can make swing arm inner sleeve be subject to axial force, rubber sleeve main body 2 has preferable resistance to deformation energy
Power, can effectively play the damping effect of rubber sleeve main body 2.Herein, limiting section 202 is integrally formed with rubber sleeve main body 2, certainly,
Both limiting section 202 and rubber sleeve main body 2, except that can be integrally formed, can be also Split type structure, and limiting section 202 such as is adhered into rubber
The two ends of gum cover main body 2, simply such structural strength is relatively poor.Specifically, along rubber sleeve main body 2 radially outward, rubber sleeve
The length of main body 2 is tapered into, and the diameter of limiting section 202 D1 less than outer tube 1 outer diameter D, the structure is to pacify for convenience
Dress outer tube 1.In addition, limiting section 202 can also only be located at one end of rubber sleeve main body 2 except being arranged on the two ends of rubber sleeve main body 2,
So cause the resistance capacity to deformation of rubber sleeve main body 2 poor.
In order to improve the structural strength that inner tube 3 is connected with rubber sleeve main body 2, it is formed with and rubber in the middle part of the outer wall of inner tube 3
The bite of the set occlusion of main body 2, specifically, bite includes being formed at the middle part of inner tube 3 and the footpath convex along inner tube 3 is set
First bite 301, in the radial direction of inner tube 3, the height H1 of the first bite 301 is the 2/9~4/ of the thickness T of rubber sleeve main body 2
9, optimal design is 1/3, and the length L1 of the first bite 301 is about the 1/2 of the length L of outer tube 1, and said structure can make this bush of swing arm
Ability with preferably resistance axial deformation, while inner tube 3 is ensured with 2 junction structural strength of rubber sleeve main body, protects
Demonstrate,prove the damping property of the rubber sleeve main body 2.Certainly, the height H1 of the first bite 301 is except that can be the thickness T of rubber sleeve main body 2
2/9~4/9, it can also be more than the 4/9 of the thickness T of rubber sleeve main body 2, or less than the 2/9 of the thickness T of rubber sleeve main body 2, simply work as
When it is more than the 4/9 of the thickness T of rubber sleeve main body 2, the damping property of this rubber sleeve main body 2 can be made to be deteriorated, and work as it and be less than rubber sleeve
The thickness T of main body 2 2/9 when, the resistance axial deformation of inner tube 3 and rubber sleeve main body 2 can be made less able, and make the junction structure
Intensity is deteriorated.Additionally, the longitudinal section of the first bite 301 is also in approximate trapezoid, that is, the first bite 301 is in gradually evagination, this
The above-mentioned hollow-out parts 201 of respective outer side edges so that this bush of swing arm has structural strength higher, and with preferably damping
Energy.
In addition, bite also includes on the length direction of inner tube 3, set with the spacing of the first bite 301 and along inner tube 3
The second bite 302 for setting of footpath convex, and in the radial direction of inner tube 3, the height H2 of the second bite 302 stings less than first
The height H1 in conjunction portion 301, optimal design be the second bite 302 height H2 be about the first bite 301 height H1 1/
2, the second bite 302 and the first bite 301 so coordinate, and can lift the cementability after inner tube 3 vulcanizes with rubber sleeve main body 2
Can so that the connection between inner tube 3 and rubber sleeve main body 2 is more solid and reliable, and further lift this bush of swing arm resistance axle
To the ability of deformation.
State during the present embodiment application as shown in Fig. 2 it is installed at the bush of swing arm installation position 6 of swing arm 5, and rear
Rear-swing arm bushing is equiped with bush of swing arm installation position 4, wherein, this bush of swing arm can provide enough axial rigidities, namely
It has the ability of preferably resistance axial deformation, additionally, it has relatively low radial direction torsional rigidity, in adaptation vehicle traveling
Damping requirements, are applied to that in vehicle riding comfort can be improved.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
