Abstract
The utility model discloses a multi wheel driven electric car, which belongs to a vehicle. The utility model is composed of a car frame, wheels and a main shaft of the car, wherein a stator hollow shaft is arranged outside the main shaft of the car; one end of the main shaft of the car is provided with a main shaft nut and an opening pin of a pin shaft. A rotor is arranged outside the stator hollow shaft; the stator hollow shaft is connected with the rotor through a bearing; both sides of the stator hollow shaft and the rotor are respectively provided with inner end covers and outer end covers; the external side of the rotor is connected with the wheels. The multi wheel driven electronic car of the utility model disuses a chain or a transmission shaft; the wheels can be directly driven by the motor; thereby, a differential mechanism, etc. can be omitted, and the weight of a car body can be lightened. When running, the utility model can conveniently use single wheel driving or multi wheel driving according to actual conditions; thereby, the energy loss can be reduced.
Description
1, technical field
The utility model relates to a kind of vehicle, specifically a kind of multiple-wheel drive battery-driven car.
2, technical background
Battery-driven car in the market all is to use series dc motor, the shortcoming of this kind electrical motor is that its rotor, stator is series operation, by the storage battery supply of electrical energy, in rotor, stator, produce magnetic field, under the effect in magnetic field, the power that rotates, so power supply will produce magnetic field for stator, produces magnetic field for rotor again.So just increased electric energy loss.Want to increase the once electrically-charged operating range of battery-driven car in this case and will increase accumulator capacity, can increase the weight of whole battery-driven car simultaneously, and then increase degradation of energy.
3, summary of the invention
Technical assignment of the present utility model is at above weak point, and a kind of simple in structure, multiple-wheel drive battery-driven car that productive costs is low, in light weight, energy-conservation is provided.
The technical scheme that its technical matters that solves the utility model adopts is: car owner's axle arranged outside has the stator hollow shaft, and car owner's axle one end is provided with spindle nut, bearing pin spring cotter; Stator hollow shaft arranged outside has rotor, is connected by bearing between stator hollow shaft and the rotor, and stator hollow shaft, rotor both sides are respectively arranged with inner end cap and outer end cap; The rotor outside links to each other with wheel.
Described inner end cap one side is provided with brake shoes, and brake shoes and brake connecting rod link together.
Two car owner's axles of described electric motor car with two wheels adopt identical structure.
Three car owner's axles of described three-wheeled electric vehicle adopt identical structure.
Four car owner's axles of described four-wheel electric motor car adopt identical structure.
Multiple-wheel drive battery-driven car of the present utility model is compared with prior art, and it by the motor direct-drive wheel, has saved diff etc. without chain and transmission shaft, has alleviated car body weight; Can be convenient to use single wheel drive or multiple-wheel drive according to actual conditions during operation, reduce degradation of energy.Thereby, have good value for applications.
4, description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the driver train of multiple-wheel drive battery-driven car.
Among the figure: 1, outer end cap; 2, bearing; 3, bearing pin; 4, spindle nut; 5, spring cotter; 6, rotor; 7, inner end cap; 8, brake shoes; 9, car owner's axle; 10, brake connecting rod; 11, stator hollow shaft; 12, wheel.
5, the specific embodiment
Explain below with reference to Figure of description multiple-wheel drive battery-driven car of the present utility model being done.
Multiple-wheel drive battery-driven car of the present utility model, its structure is made of vehicle frame, wheel 12 and car owner's axle 9, and car owner's axle 9 arranged outside have stator hollow shaft 11, and car owner's axle 9 one ends are provided with spindle nut 4, bearing pin 3 spring cotters 5; Stator hollow shaft 11 arranged outside have rotor 6, are connected by bearing 2 between stator hollow shaft 11 and the rotor 6, and stator hollow shaft 11, rotor 6 both sides are respectively arranged with inner end cap 7 and outer end cap 1; Rotor 6 outsides link to each other with wheel 12.Inner end cap 7 one sides are provided with brake shoes 8, and brake shoes 8 links together with brake connecting rod 10.This structure can be used on two and takes turns on battery-driven car, three-wheeled electric vehicle or the four-wheel electric motor car.
Its processing and fabricating of multiple-wheel drive battery-driven car of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
