Abstract
The utility model provides an electric bicycle rear wheel driving system, which comprises a rear fork, a bearing and a rear wheel, wherein the bearing is arranged on the rear fork, and the rear wheel is arranged on the bearing. A planetary gear reducer connected with the rear wheel is arranged at the joint of one side of the rear fork and the bearing, and a high-speed motor for driving the rear wheel through the planetary gear reducer is arranged on the outer side of the planetary gear reducer. The electric bicycle rear wheel driving system is convenient in maintenance, fault rate of the motor can be decreased, waterproofing of the motor can be enhanced, and cost of the motor is reduced.
Description
Technical field
The utility model relates to electric automobiles, is specifically related to the battery-driven car rear wheel drive system.
Background technology
Prior electric back wheels of vehicle drive system is provided with the hub-type motor that carries and drive one usually on the chain stay of back; Be used for driving to trailing wheel; Motor is very heavy, and maintenance is inconvenient, must earlier trailing wheel disassembled and could keep in repair motor from battery-driven car; Electronic devices and components in the motor are fragile, and the fault of motor is very high; The end cap attachment face of motor, particularly the waterproofing protection at bearing hole place is difficult, makes that the motor water-proofness is poor; The relative high-speed electric expreess locomotive volume of low speed wheel hub motor is bigger, and consumptions of materials such as required silicon steel sheet, magnet steel, copper cash are bigger, make motor cost higher.
Summary of the invention
The utility model technical matters to be solved is to provide the battery-driven car rear wheel drive system, and is easy to maintenance, can reduce the fault rate of motor, improves the water resistance of motor, reduces the cost of motor.
For solving above-mentioned existing technical matters; The utility model adopts following scheme: the battery-driven car rear wheel drive system; Comprise the back chain stay, be located at the bearing of back on the chain stay, be located at the trailing wheel on the bearing; One side of said back chain stay and the joint of bearing are provided with and trailing wheel bonded assembly planet wheel decelerator, and the outside of said planet wheel decelerator is provided with the high-speed electric expreess locomotive that drives trailing wheel through planet wheel decelerator.
As preferably, the left side of said high-speed electric expreess locomotive is provided with left end cap.During maintenance high-speed electric expreess locomotive Hall, only need pull down left end cap and get final product, easy to maintenance.
As preferably, the right side of said high-speed electric expreess locomotive is provided with right end cap, and said right end cap is connected through screw retention with planet wheel decelerator.Maintenance only need screw out screw during high-speed electric expreess locomotive, and right end cap is separated with planet wheel decelerator, does not dismantle directly high-speed electric expreess locomotive to be pulled down from planetary reduction gear under the situation of trailing wheel to get final product, and is easy to maintenance.
Beneficial effect:
The utility model adopts technique scheme that the battery-driven car rear wheel drive system is provided, and is easy to maintenance, reduced the fault rate of motor, improved the water resistance of motor, reduced the cost of motor.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The battery-driven car rear wheel drive system; Comprise back chain stay 6, be located at the bearing 7 of back on the chain stay 6, be located at the trailing wheel 5 on the bearing 7; One side of said back chain stay 6 and the joint of bearing 7 are provided with and trailing wheel 5 bonded assembly planet wheel decelerators 4, and the outside of said planet wheel decelerator 4 is provided with the high-speed electric expreess locomotive 2 that drives trailing wheel 5 through planet wheel decelerator 4.High-speed electric expreess locomotive 2 is born driving action, and planet wheel decelerator 4 is born the carrying effect, has reduced the fault rate of motor, has prolonged the service life of each electronic component in the motor.Planet wheel decelerator 4 volumes are little, and speed ratio is big, under the situation that planet wheel decelerator 4 carries, can be equipped with little, the more powerful high-speed electric expreess locomotive of volume 2, thereby strengthen battery-driven car power.The volume of high-speed electric expreess locomotive 2 reduces, thereby has reduced the cost of motor.The left side of said high-speed electric expreess locomotive 2 is provided with left end cap 1.Pull down left end cap 1 and just can change work such as faults such as motor Hall are checked, analyzed, repairing.The right side of said high-speed electric expreess locomotive 2 is provided with right end cap 3, and said right end cap 3 and planet wheel decelerator 4 are connected through screw retention.Only need screw be screwed out, right end cap 3 is separated with planet wheel decelerator 4, not dismantle directly high-speed electric expreess locomotive 2 to be pulled down from planetary reduction gear 4 under the situation of trailing wheel 5 and get final product, easy to maintenance.High-speed electric expreess locomotive 2 has only end output, promptly outputs power in the planet wheel decelerator 4 through rotor, and the pinion carrier via this planet wheel decelerator 4 exports trailing wheel to again, and the waterproof construction protection ratio of high-speed electric expreess locomotive 2 is easier to carry out, and has improved water resistance.
The battery-driven car rear wheel drive system that the utility model provides is applicable to the battery-driven car of Electrical Bicycle, electronic trail bike, electric motorcycle vehicle.
