Three arm bodies of groove, the first sub- arm body 15 of sub- arm body 14 and second fastens composition single longitudenal arm 1, and the top of single longitudenal arm 1 is provided with vehicle frame
Attachment means 11, its end is provided with wheel rim bearing mounting base 3, and the first sub- arm body 15 of sub- arm body 14 and second is metal plate punching
Shaping.The first sub- arm body 15 of sub- arm body 14 and second being so molded using metal plate punching so that connect before and after the structure of single longitudenal arm 1
Connect using two pieces of sheet metal component splicings, structural strength is good, and tailored appearance is beautiful, and welding procedure is easily guaranteed that than pipe fitting, to brake oil
The installing accessories such as pipe are easy for installation.Wherein, the first sub- arm body 15 of sub- arm body 14 and second is welded and fixed connection.Second sub- arm body 15
On be welded with balancing pole support 6 and mounting bracket of shock absorber 7 and brake-caliper support 8.
In order to further optimize such scheme, the end of single longitudenal arm 1 has kink 12, and kink 12 can improve Dan Zong
The structural strength of arm 1.
In order to further optimize such scheme, the top of single longitudenal arm 1, i.e. single longitudenal arm 1 and the connection of frame connecting device 11
Place is provided with rear arm and strengthens metal plate 5, specifically, the pipe for setting rocker arm shaft is provided with single longitudenal arm 1, vehicle frame connection dress
The 11 i.e. pipe is put, pipe is welded and fixed with single longitudenal arm 1, the problem of being set due to angle, single longitudenal arm 1 is to tilt relative to pipe
Set, then have the angle of an acute angle between the two, rear arm is strengthened metal plate 5 and is just arranged in this angle, after shake
It is that triangle rear arm strengthens metal plate that arm, which strengthens metal plate 5, and triangle rear arm strengthens the base of metal plate and pipe is welded, and it grows oblique
Side is welded with single longitudenal arm 1, can preferably improve structural strength, the acute angle that triangle rear arm strengthens metal plate be with it is described above
Angle it is equal, such triangle rear arm is strengthened metal plate and fitted with pipe and single longitudenal arm 1 while can be more preferably welding.
Wherein, for rear arm strengthen metal plate 5 for, rear arm strengthen metal plate 5 be by the 3rd left wall 51, the 3rd lower wall and
3rd right wall is connected in sequence the reeded three arms body of tool of composition, structural strength more preferably, stiffening effect more preferably, while the
Through hole is offered in three left walls 51, the 3rd lower wall and the 3rd right wall, on the premise of structural strength is ensured, is reduced under itself spring
Quality, wherein, the 3rd left wall 51 is as triangle, and the 3rd lower wall is rectangle, and the 3rd right wall is triangle, then the 3rd left wall
51 and the triangle through hole 52 for being shaped as itself scaled down of the 3rd through hole in right wall, the through hole on the 3rd lower wall be from
The rectangular through-hole of body scaled down.
Wherein, the connection of single longitudenal arm 1 and wheel rim bearing mounting base 3 is welded and fixed, the rear rim of conventional beach buggy
Bearing mounting base is separately installed an aluminum component or steel-casting, and by setting mounting hole and bolt to realize, wheel rim bearing is installed
The connection of seat and rear arm, can so cause that rear rim bearing mounting base is complex-shaped, and cost is higher, and installation procedure is more, right
The machining accuracy and assembly precision of mounting hole require high, and installation position can produce larger abrasion by long-time use, influence
Trailing wheels.The wheel rim bearing mounting base 3 provided in the beach buggy rear arm that the utility model embodiment is provided is actually one
Individual sleeve pipe, is integrally formed, the simple cost of this planform is relatively low with single longitudenal arm 1 by being welded on single longitudenal arm 1, can reduce part
Installation procedure, processing dimension and installation accuracy are guaranteed.Structure is stronger, good using relatively low trailing wheels of wearing and tearing for a long time.
Specifically, both welding position designs are as follows：The portion of protruding above 13 is provided with the connection end of single longitudenal arm 1 convex with
Go out on portion, wheel rim bearing mounting base 3 and be provided with annular groove 31, protrude above portion 13 and be weldingly fixed in the upper half groove of annular groove 31,
Lower protuberance is weldingly fixed in the lower half groove of annular groove 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 weldering of second sub- arm body 15 and wheel rim bearing mounting base 3
The place of connecing is shorter than the weld of the first sub- arm body 14 and wheel rim bearing mounting base 3 so that the first sub- arm body 14 is in itself and wheel rim
The weld formation of bearing mounting base 3 protrudes above portion 13 and lower protuberance.In order to further improve welding effect, the first sub- arm body
14 have a groove 4 in the weld of itself and wheel rim bearing mounting base 3, and the top of groove 4 is protrudes above under portion 13, groove 4
Portion is lower protuberance, and the bottom of groove 4 is circular and welding of being fitted with the bottom of annular groove 31, and such bonding area is bigger, Gu
Determine effect more preferable.
Meanwhile, one kink 2 is set again in the weld of the second sub- arm body 15 and wheel rim bearing mounting base 3, further
Improve the structural strength of both the second sub- arm body 15 and wheel rim bearing mounting base 3 itself and improve bonding area.
Be provided with through hole on such scheme, single longitudenal arm 1 to further optimize, this through hole be for riveting nut,
Specifically, nut is tack hexagonal riveting nut, through hole is hexagon ring 16.Conventional beach buggy brake oil pipe etc. need to be from rocking arm
The part of arrangement is all using the spot welding nut assembling on rocking arm, process trouble and influence outward appearance.The utility model embodiment is provided
Beach buggy rear arm in be that metal plate punching goes out hexagon ring 16 on rocking arm metal plate, nut riveting is arrived using hexagonal riveting nut
On rocking arm, structure and technique are simple, and do not influence rocking arm outward appearance, easy to assembly.
The utility model embodiment also provides a kind of beach buggy, including single longitudenal arm, and single longitudenal arm is as above-mentioned any one is real
Apply the single longitudenal arm described in example.
