Bush of swing arm is the vibration isolation and product life for meeting hollow direction at present, using hollow plus collision block structure, during use,
After inner ring rubber is contacted with outer ring collision block, rigidity is steeply risen, and the impact of road surface and wheel can be made to pass to vehicle body, to make
Comfort is obtained to be deteriorated.The design for how advanced optimizing bush of swing arm is more and more urgent.
Summary of the invention
In order to overcome the above problem, the utility model provide it is a kind of meet rigidity of structure requirement, from heavy and light, and effective damping
Prevention impact bush of swing arm.
The technical solution of the utility model be to provide it is a kind of prevent impact bush of swing arm comprising the inner tube of a lengthwise, institute
The rubber bodies for being socketed a tubular outside inner tube are stated, a metal outer pipe is socketed outside the rubber bodies, one is arranged in said inner tube to outer ring
The bulge body of shape protrusion, the rubber bodies are arranged in the bulge in vitro to coat the bulge body, it is characterised in that: the rubber
Along the groove of at least two perforation of its axisymmetrical setting on colloid outer wall, the bottom portion of groove is provided at least one convex
Convex block out, the outer tube wall correspond to the collision block that arc is provided at the convex block.
Preferably, the projecting point of several protrusions is arranged in a side surface of the collision block towards the convex block.
Preferably, the collision block is made of rubber or plastics, and is pasted on the outer tube wall.
Preferably, the collision block and rubber bodies are integrally formed.
Preferably, bulge body highest point is the 1/4- of the rubber body thickness to the distance between said inner tube outer wall
1/3。
Preferably, the rubber bodies inner wall is glued on said inner tube outer wall by viscose glue, and the rubber bodies outer wall passes through
Viscose glue is glued on the inner wall of the outer tube.
Preferably, the rubber bodies both ends are provided with along said inner tube outer wall respectively to the attached of said inner tube one end extension
Portion.
Preferably, the length of the facies posterior hepatis of any end is the 1/3 ~ 1/2 of the length of rubber bodies.
Preferably, the outer tube is aluminum pipe.
The prevention impact bush of swing arm of the utility model connects outer tube and inner tube using rubber, and raw steel matter outer tube is changed
Into for aluminum pipe, and rigidity is improved using the bulge structure of inner tube.After adopting the above structure, before ensuring to meet rigidity requirement
It puts, so that the self weight of prevention impact bush of swing arm mitigates significantly, and improves bush of swing arm stiffness curve using convex block, so that preceding
Rear end stiffness variation slows down, and improves passenger comfort.
Detailed description of the invention
Fig. 1 is a kind of top view for preventing to impact bush of swing arm of the best embodiment of the utility model;
Fig. 2 is sectional view along A-A in Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below.
As depicted in figs. 1 and 2, a kind of steel inner tube for preventing to impact that bush of swing arm includes a lengthwise of the utility model
10.The outer tube 12 of an aluminum is socketed outside inner tube 10.
In order to connect inner tube 10 and outer tube 12, filled rubber forms rubber bodies 14 between inner tube 10 and outer tube 12, thus
The characteristic of rubber shock-absorbing is made full use of to reduce the transmitting of the vibration between inner tube 10 and outer tube 12.
But rubber is softer, so that the rigidity of structure is reported to the leadship after accomplishing a task between inner tube 10 and outer tube 12, structural stability is reported to the leadship after accomplishing a task.For
This, is arranged a bulge body 16 that annular is protruded outward in inner tube 10, and the setting of rubber bodies 14 is outer to coat bulge in bulge body 16
Body 16.Further, 16 highest point of bulge body is the 1/4-1/3 of 14 thickness of rubber bodies to the distance between 10 outer wall of inner tube,
In preferably 1/4.By the bulge body 16 of the protrusion, so that 14 thickness of rubber bodies of central part reduces, and can make full use of interior
The rigidity of pipe 10 improves integrally-built rigidity.
14 inner wall of rubber bodies is glued on 10 outer wall of inner tube by viscose glue, and 14 outer wall of rubber bodies is glued at outer tube by viscose glue
On 12 inner wall.
14 both ends of rubber bodies are provided with along 10 outer wall of the inner tube facies posterior hepatis 18 that 10 one end of pipe extends respectively inwards.
The length of the facies posterior hepatis 18 of any end is the 1/3 ~ 1/2, preferably 1/2 of the length of rubber bodies 14, and facies posterior hepatis 18 can
To improve bond area of the rubber bodies 14 in inner tube 10, bonding strength is improved, and shake convenient for absorbing inner tube 10.
Further, the groove 20 of 2 perforations, the setting of 20 bottom of groove are set on 14 outer wall of rubber bodies along its axisymmetrical
1 convex block 22 outwardly protruded, 12 inner wall of outer tube correspond to the collision block 24 that arc is provided at convex block 22.Collision block 24 is towards convex block 22
A side surface be arranged several protrusion projecting point 26.Make using the above structure:
The setting buffering convex block 22 of rubber bodies 14, when small amplitude, do not contact with outer ring collision block 24, guarantee vibration isolating effect；
When road surface and larger wheel transmitting amplitude, convex block 22 is first contacted with external collision block 24, since area is smaller, will not be produced
Raw impact realizes that rigidity is slowly varying in compression process.To obviously slow down stiffness variation, prevent impact bring uncomfortable
Sense.
Above embodiments are only the one such embodiment of the utility model, and the description thereof is more specific and detailed, but simultaneously
Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention.It should be pointed out that for the ordinary skill of this field
For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this
The protection scope of utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
