The utility model has ingenious design, simple and compact structure, and is easy to arrange. The power assembly adopts a four-point suspension structure. During the driving process, the vehicle shakes slightly, and the comfort is good. The suspension rubber deformation is small and the service life is long.
Description
Technical field
The utility model belongs to electric vehicle engineering field, specifically, and particularly a kind of electrical vehicular power assembly four point suspension structure.
Background technology
Battery-driven car is using battery as energy source, by the parts such as controller, motor, is mechanical energy motion by electric energy conversion, to control the vehicle that size of current changes speed.Traditional electrical motor-car dynamic assembly mounting means is three-point suspension, and because suspension arrangement structure limit, when driving, vehicle can produce violent shake, and traveling comfort is poor, and rear-suspending Rubber Parts deflection is comparatively large simultaneously, and the life-span is shorter.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of electrical vehicular power assembly four point suspension structure.
Technical solutions of the utility model are as follows: a kind of electrical vehicular power assembly four point suspension structure, comprise dynamic assembly and car body, it is characterized in that: above described dynamic assembly front end, be provided with about two front-suspensions side by side, the first bolt that dynamic assembly front end is fixed is through front-suspension, by the first nut locking, the center of each front-suspension wears the first overbolt and is fixedly connected with car body; About two rear-suspendings are side by side provided with above described dynamic assembly rear end, two rear-suspendings and two front-suspensions are by the rectangular distribution, and two rear-suspendings are welded on same support, this support is fixed by the second bolt and dynamic assembly, and the center of each rear-suspending wears the second overbolt and is fixedly connected with car body.
The utility model dynamic assembly adopts four point suspension structure, and when driving, vehicle shake is slight, and traveling comfort is better, and suspended rubber deflection is little, and the life-span is long; Meanwhile, this four point suspension compact conformation, facilitates arrangement.
Described support is flat " U " shape, and shaping by steel plate punched, and bottom surface and the dynamic assembly of support fit, and support is fixed by four the second bolts by the rectangular distribution and dynamic assembly.Above structure on the one hand support moulding is simple, and be easy to processing and fabricating, intensity is good, not easily deforms; On the other hand, support is combined closely with dynamic assembly, and disassembling operations is convenient, the fastness of connection and good reliability.
The end face at two ends, described support left and right is recessed arc surface, and this arc surface fits with the outer circumference surface of corresponding rear-suspending, and by being welded and fixed.Area of contact between above structure rear-suspending and support is large, connects fixing good.
Beneficial effect: the utility model design is ingenious, and structure is simple, compact, be easy to arrange, dynamic assembly adopts four point suspension structure, and when driving, vehicle shake is slight, and traveling comfort is better, and suspended rubber deflection is little, and the life-span is long.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one detailed description of the invention.
Fig. 2 is STRUCTURE DECOMPOSITION figure of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, be provided with about two front-suspensions 2 side by side, each front-suspension 2 carries locating plate above dynamic assembly 1 front end, the first bolt 3 that dynamic assembly 1 front end is fixed, through the locating plate on front-suspension 2, is locked by the first nut 4.As preferably, dynamic assembly 1 is connected with front-suspension 2 by three the first bolts 3 by equicrural triangle distribution.The center of each front-suspension 2 wears the first overbolt 7 and is connected with car body, also passes through nut locking.
As shown in Figure 1 and Figure 2, above dynamic assembly 1 rear end, be provided with about two rear-suspendings side by side 5, two rear-suspendings 5 and two front-suspensions 2 by the rectangular distribution, the center of each rear-suspending 5 wears the second overbolt 9 and is fixedly connected with car body.Two rear-suspendings 5 are arranged on same support 6, are specially: support 6 is flat " U " shape, and shaping by steel plate punched, and bottom surface and the dynamic assembly 1 of support 6 fit, and support 6 is fixed by four the second bolts 8 by the rectangular distribution and dynamic assembly 1.The end face at support about 6 two ends is recessed arc surface, and the arc surface at top, support about 6 two ends and two rear-suspending 5 one_to_one corresponding, each arc surface fits with the outer circumference surface of corresponding rear-suspending 5, and by being welded and fixed.
Above-mentioned front-suspension 2 and rear-suspending 5 are existing matured product, and its structure does not repeat at this.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical personnels in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
