Embodiment
Fig. 3 and Fig. 4 are referred to, it is respectively top view and the master of the locomotive frame of the preferred embodiment of the utility model first
View.The locomotive frame 10 of the utility model embodiment includes：One head tube 20, one is responsible for 30, two looped pipelines 40, two front end reinforcement
Piece 43, two rear end reinforcing chips 44, two rear shock absorber supports 45, a support connecting tube 52, two side pipes 54, a storage box connecting tube
56th, an endpiece connecting tube 59 and two endpiece connecting tube reinforcing chips 591.
As illustrated, supervisor 30 is connected with head tube 20；Each looped pipeline 40 includes a leading portion portion 41 and a back segment portion 42, often
One looped pipeline 40 is two-piece isolating construction, and leading portion portion 41 includes a horizontal segment of linkage section 411 and one being connected with supervisor 30
412, be installed with a support 50 to fixed locomotive engine (not shown) on the horizontal segment 412, back segment portion 42 include one with
Ascent stage 421, an expansion segment 422, a converging transition 423 and the endpiece 424 that horizontal segment 412 connects.Support connecting tube 52 its
Two ends are fixedly arranged on two supports 50 respectively；Two side pipes 54 respectively with the side of left and right two of supervisor 30 and the leading portion portion 41 of two looped pipelines 40
Horizontal segment 412 connects；And two ends of storage box connecting tube 56 are fixedly arranged on the ascent stage 421 in the back segment portion 42 of two looped pipelines 40 respectively.
Two front end reinforcing chips 43 be fixedly arranged on respectively the upper end of the horizontal segment 412 of two looped pipelines 40 and ascent stage 421 front end it
Between, two rear end reinforcing chips 44 are fixedly arranged between the upper end and the rear end of ascent stage 421 of the horizontal segment 412 of two looped pipelines 40 respectively, tail
Two ends of section connecting tube 59 are fixedly arranged on the endpiece 424 in the back segment portion 42 of two looped pipelines 40 respectively, and two endpiece connecting tube reinforcing chips 591 divide
It is not fixedly arranged between endpiece 424 and the endpiece connecting tube 59 of two looped pipelines 40, to strengthen rigidity of vehicle body intensity.
In the present embodiment, two looped pipelines 40 are that symmetrical formula is set, and the spacing of the expansion segment 422 of two looped pipelines 40 is big
In the spacing of converging transition 423, and the spacing of the converging transition 423 of two looped pipelines 40 is more than the spacing of endpiece 424.Therefore, car body can be made
Tail end it is tapered, in visually there is the aobvious thin effect of the extension for elongating car body.In addition, two rear shock absorber supports 45 are fixedly arranged on respectively
The endpiece 424 of two looped pipelines 40, to the rear shock absorber (not shown) of fixed locomotive, because vehicle frame 10 by middle-end to tail end be adopt it is tapered
Design, the spacing of the endpiece 424 of two looped pipelines 40 is minimum, therefore the spacing of two rear shock absorber supports 45 can reduce, except can strengthen
Outside the intensity of rear shock absorber support 45, overall structure can also simplified, lightweight, cost and mould, work, control, cubing investment it is equal
It can decline
In the present embodiment, the leading portion portion 41 of each looped pipeline 40 and back segment portion 42 are for identical material, caliber and the thickness of pipe.
Certainly, the utility model according to different automobile types, can also adjust the leading portion portion 41 of each looped pipeline 40 and the style and tendency in back segment portion 42,
Diversified and modular locomotive frame is developed, lifts design flexibility.
Thus, two looped pipelines 40 of the vehicle frame 10 of the present embodiment are two-piece isolating construction, and two looped pipelines 40 are respectively divided into a leading portion
Back segment portion 42 of portion 41 and one, the looped pipeline 84 different from existing vehicle frame 80 (as shown in Figure 1, 2) be using integrally formed mode to
Rear end extends；In addition, the support 50 of the present embodiment is the lower end of a horizontal segment 412 in the leading portion portion 41 for being connected to looped pipeline 40, and
The support 85 of existing vehicle frame 80 is disposed on the bending part of two looped pipelines 84, and bending part is the relatively weak place of category rigidity of vehicle body, because
This this case and existing vehicle frame are compared down, and the intensity of rigidity of vehicle body is preferable, and supporting structure is simplified, lightweight, cost and mould, work,
Control, cubing investment can decline.In addition, the supervisor 30 of the present embodiment, the leading portion portion 41 of looped pipeline 40 and the three of side pipe 54 form one
Three-dimensional triangle structure, the rigid except can be used to strengthen overall car body, to resist outside the bending moment suffered by car body, and three
The space that person is formed, it can also be effectively increased the accommodation space of fuel tank.
Refer to the front view that Fig. 5 is the locomotive frame of the preferred embodiment of the utility model second, the present embodiment and first
The structure of embodiment is roughly the same, and its difference is only that the horizontal segment 4120 of the looped pipeline 400 of the present embodiment extends back, and sets up
One support connecting tube 58, two ends of support connecting tube 58 are fixedly arranged on rear end and the back segment of the horizontal segment 4120 of two looped pipelines 400 respectively
Portion 42, to strengthen rigidity of vehicle body intensity, to resist the bending moment suffered by car body.That is, before the looped pipeline 400 of the present embodiment
Two ends in section portion 410 are respectively linkage section 4110 and horizontal segment 4120, and linkage section 4110 is connected with supervisor 30, and horizontal segment 4120
Then it is connected with support connecting tube 58.
Thus, the present embodiment is in addition to the effect of can reach first embodiment, and the support connecting tube 58 of the present embodiment, looped pipeline
The horizontal segment 4120 in 400 leading portion portion 410 and the three of back segment portion 42 form a Three-dimensional triangle structure, can be used to strengthen overall car body
Rigid, to resist the bending moment suffered by car body.
