Specific embodiment
Embodiments of the invention are described below in detail, the example of embodiment is shown in the drawings, wherein identical from start to finish
Or similar label represents same or similar element or the element with same or like function.Retouched below with reference to accompanying drawing
The embodiment stated is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
As shown in Figures 3 to 5, a kind of bush of swing arm mounting structure is the embodiment of the invention provides, wherein, including：Swing arm
Bushing 1, swing arm 2, frame cross 3 and installation bolt 4, bush of swing arm 1 include inner sleeve 11, outer tube 12 and vulcanization in inner sleeve
Rubber 13 between pipe 11 and outer tube 12, inner sleeve 11 includes hollow pipe 111 and the linking arm positioned at the two ends of hollow pipe 111
112, the linking arm 112 at two ends is equipped with first through hole 113；The swing arm sleeve pipe 21 of swing arm 2 is set on outer tube 12；Vehicle frame is horizontal
The middle part of beam 3 is provided with boss face 31, and both sides are level board 32, and two level boards 32 are equipped with second coordinated with first through hole 113
Through hole 321；Installation bolt 4 passes through the through hole 321 of first through hole 113 and second, connects inner sleeve 11 and frame cross 3.Due to car
Frame crossbeam 3 is formed in one, and rigidity is higher, is directly connected by installation bolt 4, and bush of swing arm 1 can be made to be connected with frame cross 3
It is relatively reliable；The fastening force that installation bolt 4 is provided is identical with gravity direction, can avoid producing shearing force to installation bolt 4, full
In the case of sufficient fastening force, the size of installation bolt 4 can be reduced, reduce weight.
As shown in figure 4, further, swing arm sleeve pipe 21, outer tube 12, the axial length of rubber 13 are respectively less than or equal to sky
The axial length of heart pipe 111, can make respective outer side edges compacter, convenient for assembly.
Two linking arms 112 can have various with the connected mode of hollow pipe 111, for example, two linking arms 112 are separately fixed at
The two ends of hollow pipe 111, but the two ends port of hollow pipe 111 is not blocked.The present embodiment is preferably, linking arm
The pore of 112 closure hollow pipes 111, can increase bonding strength, while avoiding liquid from flowing into pore, rust be caused to inner sleeve 11
Erosion, reduces the service life of inner sleeve 11.
The present embodiment it is further preferred that the structure that is formed in one of linking arm 112 and hollow pipe 111, as shown in figure 4,
The two ends of inner sleeve 11 are flattened the linking arm 112 to form both sides, middle part forms the hollow pipe 111 with cavity, the structural strength
Higher, cost is relatively low.
Further, linking arm 112 and the mating surface of level board 32 are plane, by increasing contact area, can make installation
It is more reliable with level board 32 that bolt 4 is fastenedly connected arm 112.
Further, 112 one-tenth flat of linking arm, it is possible to increase installation bolt 4 and the contact area of linking arm 112, it is possible to
Reduce the weight of linking arm 112.
As shown in Figure 5, it is preferable that the second through hole 321 is mounting hole, facilitates the linking arm 112 of installation bolt 4 and level
Plate 32.
Further, two the second through holes 321 are perpendicular, can be by changing the fixed position of installation bolt 4, adjustment pendulum
The position of arm bush 1, drives the knuckle and wheel of the other end ball pin of swing arm 2 connection, realizes the adjustment of wheel alignment parameter.
Further, boss face 31 is trapezoid boss face, it is to avoid during adjustment swing arm 2, and boss face 31 occurs dry with swing arm 2
Relate to, meanwhile, the convenient processing in trapezoid boss face, support strength are higher.
Construction of the invention, feature and action effect is described in detail according to the embodiment shown in schema above, the above is only
It is presently preferred embodiments of the present invention, but the present invention is not to limit practical range shown in drawing, it is every according to conception institute of the invention
The change of work, or be revised as the Equivalent embodiments of equivalent variations, still without departing from specification and diagram covered it is spiritual when, all should
Within the scope of the present invention.
