Arm 1 is symmetrical configuration with rear right rocking arm 2, therefore only carries out structure description to rear left rocking arm 1 below, wherein, rear left rocking arm 1 includes
The sub- arm body 15 of first sub- arm body 14 and second, the first sub- arm body 14 is to be connected successively by the first left wall, the first lower wall and the first right wall
Connect the reeded three arms body of tool for forming composition, the second sub- arm body 15 be by the second left wall, the second lower wall and the second right wall successively
Be formed by connecting the reeded three arms body of tool of composition, and the sub- arm body 15 of the first sub- arm body 14 and second fastens composition rear left rocking arm 1, after
The top of left rocking arm 1 is provided with frame connecting device 11, and its end is provided with trailing wheel mounting bracket 3, the end tool of rear left rocking arm 1
There is kink 12, kink 12 is connected with rear shock absorber assembly 4.By the way that using single trailing arm type independent suspension structure, suspension can be made
Larger stroke is obtained, comfortableness is good, and the space of occupancy car load is less, and wheel is without lateral slip, simple structure dress
With convenient.
In order to further optimize such scheme, the sub- arm body 15 of the first sub- arm body 14 and second is punch forming.Existing skill
Rocking arm in art uses and pipe fitting connection is connected by before and after pipe fitting, i.e. beach buggy rocking arm, causes welding procedure complicated, and
Pipe fitting resistance to torsion does not with great difficulty produce elastic deformation, then using the sub- arm body 15 of the stamping forming first sub- arm body 14 and second,
So that being connected by two pieces of sheet metal component splicings before and after the structure of single longitudenal arm, structural strength is good, and tailored appearance is beautiful, welding procedure ratio
Pipe fitting is easily guaranteed that, easy for installation to installing accessories such as brake pipes.Wherein, the sub- arm body 15 of the first sub- arm body 14 and second is welded
It is fixedly connected.
In order to the middle part for further optimizing such scheme, rear left rocking arm 1 and rear right rocking arm 2 is connected by rear torque arm 8,
Rear torque arm 8 is just provided with, the effect of rear torque arm 8 is, when the level height of left and right two-wheeled is different, to produce anti-dumping resistance
Suppressed.Wherein, the end of rear left rocking arm 1 has kink 12, and the structure that kink 12 can improve rear left rocking arm 1 is strong
Degree, and also kink 12 can be provided with mud guard 6, the mud guard 6 is fixed on kink 12 with rear shock absorber assembly 4
On junction.Grass guard 7 can be provided with the side towards wheel in trailing wheel mounting bracket 3, grass guard 7 is disk and gear
Multiple through holes are provided with careless plate 7.
In order to further optimize such scheme, reinforcement 5 is provided with frame connecting device 11, specifically, rear left rocking arm 1
On be provided with pipe for arranging rocker arm shaft, the frame connecting device 11 i.e. pipe, pipe is welded and fixed with rear left rocking arm 1,
Due to the problem that angle is arranged, rear left rocking arm 1 is obliquely installed relative to pipe, then have acute angle between the two
Angle, reinforcement 5 is just arranged in this angle, and reinforcement 5 is triangle reinforcement, the base of triangle reinforcement and pipe
Welding, its long hypotenuse welds with rear left rocking arm 1, can preferably improve structural strength, the acute angle of triangle reinforcement be with it is upper
Angle described in face is equal, such triangle reinforcement can more preferably while fit with pipe and rear left rocking arm 1 welding.
Wherein, for reinforcement 5, reinforcement 5 is to be sequentially connected by the 3rd left wall 51, the 3rd lower wall and the 3rd right wall
The reeded three arms body of tool of composition is formed, more preferably, stiffening effect is more preferable, while under the 3rd left wall the 51, the 3rd for structural strength
Through hole is offered in wall and the 3rd right wall, on the premise of structural strength is ensured, itself unsprung mass is reduced, wherein, the 3rd
As triangle, the 3rd lower wall is rectangle to left wall 51, and the 3rd right wall is triangle, then in the 3rd left wall 51 and the 3rd right wall
Through hole the triangle through hole 52 for being shaped as itself scaled down, the through hole on the 3rd lower wall is itself scaled down
Rectangular through-hole.
Wherein, the connection of rear left rocking arm 1 and trailing wheel mounting bracket 3 is welded and fixed, the rear trailing wheel of conventional beach buggy
Mounting bracket is a separately installed aluminum component or steel-casting, by installing hole is set and bolt realize trailing wheel mounting bracket with
The connection of rear arm, can so cause that trailing wheel mounting bracket is complex-shaped, and relatively costly, installation procedure is more, to installing hole
Machining accuracy and assembly precision have high demands, installation position can produce larger abrasion through long-time use, affect trailing wheel to determine
Position.The trailing wheel mounting bracket 3 provided in beach buggy rear arm provided in an embodiment of the present invention is actually a sleeve pipe, by weldering
It is connected on rear left rocking arm 1 and is integrally formed with rear left rocking arm 1, the simple cost of this planform is relatively low, part installation procedure can be reduced,
Processing dimension and installation accuracy are guaranteed.Structure is stronger, good using the relatively low trailing wheels of abrasion for a long time.
Specifically, both welding position designs are as follows：The connection end of rear left rocking arm 1 be provided with the portion of protruding above 13 and under
Protuberance, is provided with cannelure 31 in trailing wheel mounting bracket 3, protrude above portion 13 and be weldingly fixed in the upper half groove of cannelure 31,
Lower protuberance is weldingly fixed in the lower half groove of cannelure 31, and such bonding area is bigger, and fixed effect is more preferable.
Wherein, the design for protruding above portion 13 and lower protuberance is as follows：The welding of the second sub- arm body 15 and trailing wheel mounting bracket 3
Place is shorter than the weld of the first sub- arm body 14 and trailing wheel mounting bracket 3 so that the first sub- arm body 14 is installed in itself and trailing wheel
The weld of support 3 is formed and protrudes above portion 13 and lower protuberance.In order to further improve welding effect, the first sub- arm body 14 is certainly
Body has groove with the weld of trailing wheel mounting bracket 3, and to protrude above portion 13, the bottom of groove is lower protrusion on the top of groove
Portion, the bottom of groove is circular and welding of fitting with the bottom of cannelure 31, and such bonding area is bigger, and fixed effect is more preferable.
Meanwhile, in the weld of the second sub- arm body 15 and trailing wheel mounting bracket 3, a kink is set again, further improve
The structural strength of the second sub- arm body 15 and trailing wheel mounting bracket 3 both itself and improve bonding area.
In order to further optimize such scheme, through hole is provided with rear left rocking arm 1, this through hole is for riveting nut
, specifically, nut is tack hexagonal riveting nut, and through hole is hexagon ring 16.Conventional beach buggy brake oil pipe etc. need to be from shaking
The part arranged on arm is all using the spot welding nut assembling on rocking arm, operation trouble and impact outward appearance.The embodiment of the present invention is provided
Beach buggy rear arm in be the punching press hexagon ring 16 on rocking arm panel beating, using hexagonal riveting nut by nut riveting to rocking arm
On, structure and process is simple, and rocking arm outward appearance is not affected, it is easy to assembly.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or using the present invention.
Various modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, the present invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The most wide scope for causing.
