A kind of rear drive battery-driven car chassis
Technical field
The utility model relates to a kind of battery-driven car chassis, particularly relates to a kind of rear drive battery-driven car chassis.
Background technology
At present, be used for the chassis of battery-driven car, its constituent elements and structure all are employing golf chassis or make amendment and design-calculated on its basis that the chassis tractive performance of this structure is poor, and load carrying ability is little, and traveling comfort is not good enough, and the place scope that is suitable for is little.Part adopts the battery-driven car of chassis of the minitype automobile repacking mostly to be f-w-d, easily causes battery-driven car climbing power deficiency, can not give full play to alternating current dynamo output and turn round the big advantage of refusing.
The utility model content
Problem to be solved in the utility model provides the battery-driven car chassis of a kind of front wheel independent suspension, alternating current dynamo rear drive.
The technical scheme that the utility model adopted is: rear drive battery-driven car chassis comprises vehicle frame and actuating device, described actuating device comprises AC driven motor, controller, retarder, battery pack, independent suspension front-wheel, back axle, described front-wheel is an independent suspension, controller and part arranging batteries are between two front-wheels, described AC driven motor and retarder are arranged in the vehicle frame middle part, back axle is a drive axle, is connected with retarder by transmission shaft.
As the further improvement of such scheme, described AC driven motor is controlled alternating current dynamo.
Described suspension comprises elastic element and damping element, is preferably damping spring and bumper, can further improve the traveling comfort of taking so compared to existing technology.
In order to improve load carrying ability, vehicle frame can adopt the heavier-duty vehicle frame, is preferably to adopt the steel tubes manufacturing.
The beneficial effects of the utility model are: after the utility model adopts back-wheel drive, can be good at bringing into play alternating current dynamo and turn round the big advantage of refusing, obviously improve the hill climbing ability of battery-driven car, tractive performance is better, applicable situation is wider, and load carrying ability and traveling comfort are further improved in also comparable Caddy repacking chassis.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
Extremely shown in Figure 2 as Fig. 1: rear drive battery-driven car chassis comprises AC driven motor 1, retarder 2, front-wheel 3, vehicle frame 4, power battery pack 5, controller 6, rear drive sprocket 7, back axle (drive axle) 8, preceding damping spring 9, front shock absorber 10, back damping spring 11, rear shock absorber 12, main driving axle 13.
The described chassis of the above-mentioned specific embodiment is the battery-driven car chassis that a kind of alternating current dynamo drives, and comprises vehicle frame and actuating device; Wherein vehicle frame 4 is a tower structure, by some affixed the forming of longitudinal and cross beam; Actuating device is located at vehicle frame 4 middle parts, comprise AC driven motor 1, retarder 2, main driving axle 13, power battery pack 5, controller 6, back axle (drive axle) 8, rear drive sprocket 7, wherein rear drive sprocket 7 is fixed on rear driving axle 8 two ends, 8 on back axle (drive axle) passes through back damping spring 11 and is connected with vehicle frame 4 with rear shock absorber 12, front-wheel 3 passes through preceding damping spring 9 and front shock absorber 10 independent suspensions respectively in the both sides of vehicle frame 4, join by main driving axle 13 between back axle (drive axle) 8 and the retarder 2, battery pack 5 is divided into several portions, a part places on the back axle (drive axle) 8, but be no more than plane on the vehicle frame 4, part places below the vehicle frame 4 middle part passenger seats and between anterior two front-wheels 3, controller 6 is positioned between two front-wheels position nearer with AC driven motor 1, the operation of direct regulation and control AC driven motor 1.
