Fig. 1 is the utility model embodiment 1 structural representation.
Reference numeral comprises: front-wheel 1, front stand 2, propons 3, girder 4, battery box 5, cross bar 6, rear vertical shaft 7, rear shock absorber 8, rear power bridge 9, front suspension 10, front shock absorber 11, end brace panel 12, rear suspension 13, trailing wheel 14.
Detailed description of the invention
The utility model principle is, traditional body-chassis frame construction needs the girder 4 that an intensity is very high, the weight of the increase vehicle chassis can given prominence to like this, can according to battery box 5 structural requirement of battery-driven car indispensability, battery box 5 can be strengthened unit as main intensity in design, thus the carrying effect of transfer girder 4, even the effect of girder 4 is set as the function being only limitted to connect forward and backward suspension.
The utility model comprises: propons 3, girder 4, battery box 5, crossbeam 6, rear vertical shaft 7, rear shock absorber 8, back axle 9 and front shock absorber 11.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the longitudinal direction that the girder 4 of two tubuloses is parallel is installed, battery box 5 is installed at middle part therebetween, and laterally parallel installation crossbeam 6, two girder 4 front ends are installed propons 3, two girder 4 rear end K/UPs and install back axle 9 between two girders 4, wherein, propons 3 has vertical square bearer structure, and shock absorber 11 before the difference at right angle setting of propons 3 both sides, back axle 9 both sides are at right angle setting rear shock absorber 8 respectively.
In aforementioned, front-wheel 1 is installed in front shock absorber 11 lower end, and trailing wheel 14 is installed in rear shock absorber 8 lower end, and trailing wheel 14 inner shafts portion upwards connects rear vertical shaft 7.
In aforementioned, propons 3 both sides are the leg-of-mutton front stand 2 of at right angle setting respectively.
