Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further detailed.
As shown in Figure 1 and Figure 2, this rear drive electric automobile comprises vehicle frame 1, battery pack 2, drive motor 4, rear driving axle 6, front suspension 7, rear suspension 8 etc.Automobile front suspension 7 adopts double cross arm independent suspension system, and rear suspension 8 adopts the semi-independent suspension system of single trailing arm type.Such suspension system can improve the ride comfort of electronlmobil, improves the riding stability of electronlmobil.
Described battery pack 2 is electrically connected with described drive motor 4.Drive motor 4 is located at rear portion, chassis, and described drive motor 4 is directly fixed on the middle part of rear driving axle 6.Specifically, described rear driving axle 6 is through the through hole 42 on the base 41 of described drive motor 4, and the opposite side of the described drive motor 4 relative with described base 41 is fixedly connected with described rear driving axle 6.Thus, drive motor 4 is directly connected with rear driving axle 6 and drives trailing wheel.
As shown in Figure 3, the opposite side of relative with described base 41 described drive motor 4 is fixedly connected with a U-bolt 15 by an auxiliary support plate 12 with described rear driving axle 6.Described auxiliary support plate 12 comprises the first connecting panel 121 and the second connecting panel 122.In the present embodiment, described first connecting panel 121 is mutually vertical with described second connecting panel 122.Described first connecting panel 121 is fixedly connected with the described opposite side (car right side) of described drive motor 4, and described U-bolt 15 is fixedly connected with described second connecting panel 122 with the state be enclosed within described rear driving axle 6.Wherein, the first connecting panel 121 is provided with 2 screws 123.Second connecting panel 122 is provided with 2 screws 124.Thus, by increasing the auxiliary support plate 12 be connected with rear driving axle 6 on the right side of drive motor 4, can prevent in vehicle rough ride process, rear driving axle 6 is because of drive motor gravity generation metaboly.
The engine installation of this rear drive electric automobile also comprises dc-dc 5, electric machine controller 3.Described battery pack 2 comprises first group 21 and second group 22.Described first group 21 is positioned at below front-row seats bucket 9, and described second group 22 is positioned at below back seat bucket 10.In the present embodiment, drive motor 4 is alternating current dynamo, and electric machine controller 3 is AC motor control.
