Description
Technical Field
The utility model relates to an automobile chassis system, concretely relates to high shock attenuation nature car swing arm.
background
The automobile lower swing arm is used for supporting an automobile body, absorbing shock and buffering vibration in running. General car lower swing arm mainly includes the swing arm body, is equipped with the ball round pin subassembly in the one end of swing arm body, is equipped with the bush at the other end of swing arm body, and wherein traditional bush mainly includes metal casing and metal inner tube to it has shock attenuation elasticity rubber to fill between metal casing and metal inner tube, and the bush of this kind of structure, its shock attenuation effect is more general, and the practicality is relatively poor, can't satisfy user's user demand already.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a simple structure, reasonable in design are provided, can conveniently realize the regulation of bush shock attenuation effect, effectively improve the high shock attenuation nature automobile swing arm of its suitability.
Therefore, the utility model discloses an adopt following scheme to realize:
High shock attenuation nature automobile swing arm has the swing arm body, the swing arm body is rectangular shaft-like the one end of swing arm body is equipped with the ball round pin subassembly the other end of swing arm body is equipped with bush, its characterized in that: the bush includes shell and metal inner tube, the inside wall of shell is equipped with first rubber hugging closely, the middle part of first rubber extends inwards and forms connecting portion, connecting portion with the middle part of metal inner tube lateral wall is connected, the lateral wall cladding of metal inner tube has second elastic rubber, the space has between second elastic rubber and the first elastic rubber, the local packing has and is sectorial third elastic rubber in the space, be equipped with the inlet port on the third elastic rubber, first, second, third elastic rubber and connecting portion enclose out the oil storage cavity.
The inner hole of the metal inner pipe is circular, and one side of the inner hole is provided with a cylindrical recess communicated with the inner hole.
The metal inner tube is in a quadrangular prism shape.
Correspond third elastic rubber still inserted fourth elastic rubber in the interval space, fourth elastic rubber's one end is connected on the installation arm, the one end of installation arm has connecting portion, the cladding of connecting portion ground around is in the lateral wall of shell, be equipped with the fixture block on the connecting portion, be equipped with the confession on the lateral wall of shell the draw-in groove that the fixture block card was gone into.
Adopt above-mentioned technical scheme, the utility model discloses an advantage does: 1. the structure is simple, the design is reasonable, and the large-scale production can be realized; 2. the first elastic rubber, the second elastic rubber and the third elastic rubber are matched with each other for damping, so that the bushing can provide a better damping effect, damping oil can be introduced into the oil storage cavity through the oil inlet hole of the third elastic rubber according to the change of the use requirement, and then the oil inlet hole is vulcanized and plugged, so that the damping effect of the bushing is further improved; the metal inner pipe is designed into a quadrangular prism shape, so that the connection between the connecting part and the metal inner pipe is simpler and more reliable; in addition, through setting up detachable fourth elastic rubber, can fill the interval space more with the cooperation of third elastic rubber for the bush can provide the shock attenuation effect that meets the requirements, satisfies user's user demand better.
Drawings
The utility model discloses there is following figure:
Fig. 1 is a schematic structural view of the present invention;
Fig. 2 is a cross-sectional view of the utility model after the fourth rubber is installed.
Detailed Description
As shown in the figure, the utility model discloses a high shock attenuation nature car swing arm, swing arm body 1 has, swing arm body 1 is rectangular shaft-like, one end at swing arm body 1 is equipped with ball round pin subassembly 2, other end at swing arm body 1 is equipped with the bush, the bush includes shell 3 and metal inner tube 6, the inside wall of shell 3 is equipped with first rubber 4 hugely, the middle part of first rubber 4 extends inwards and forms connecting portion 41, connecting portion 41 is connected with the middle part of metal inner tube 6 lateral wall, the lateral wall cladding of metal inner tube 6 has second elastic rubber 5, interval space 11 has between second elastic rubber 5 and the first elastic rubber 4, local packing has to be sectorial third elastic rubber 7 in interval space 11, be equipped with the inlet port on third elastic rubber 7, it is first, and second, third elastic rubber and connecting portion 41 enclose out oil storage cavity 9. The inner hole of the metal inner pipe 8 is circular, and one side of the inner hole 8 is provided with a cylindrical recess 81 communicated with the inner hole, so that the connecting shaft on the chassis can be stably inserted into the inner hole 8. The metal inner tube 6 is in the shape of a quadrangular prism. Corresponding to third elastic rubber 7, fourth elastic rubber 12 is further inserted into the spacing space 11, one end of the fourth elastic rubber 12 is connected to an installation arm 16, a connection portion 15 is arranged at one end of the installation arm 16, the connection portion 15 is wrapped on the outer side wall of the shell 3 in a surrounding mode, a fixture block 13 is arranged on the connection portion 15, and a clamping groove 14 for the fixture block 13 to be clamped into is formed in the outer side wall of the shell 3.
The utility model discloses a first, second and third elastic rubber cooperate the shock attenuation each other, can make the bush provide better shock attenuation effect, and according to the change of user demand, can let in the damping oil through the inlet port 71 of third elastic rubber 7 in the oil storage cavity 9, later vulcanized shutoff inlet port 71 through shutoff piece 10, further promote the shock attenuation effect of bush; the metal inner pipe 6 is designed into a quadrangular prism shape, so that the connection between the connecting part 41 and the metal inner pipe is simpler and more reliable; in addition, through setting up detachable fourth elastic rubber 12, can fill the interval space with third elastic rubber 7 cooperation more for the bush can provide the shock attenuation effect that meets the requirements, satisfies user's user demand better.
