Abstract
The utility model discloses a spherical motor-driven wheel capable of being driven by four wheels, and belongs to the field of mechanical and electrical integration. The spherical motor-driven wheel capable of being driven by the four wheels is characterized in that a wireless power transmission system receiving end, a driving motor frequency converter and a driving motor are located in the horizontal axis of the spherical motor-driven wheel, the driving motor is an alternating current motor, and an outer rotor is connected with a rim through a spoke. A wireless power transmission system transmitting end sends signals, the wireless power transmission system receiving end receives the signals, after the frequency control of the driving motor frequency converter, currents are supplied to the driving motor, the driving motor drives the spherical motor-driven wheel to rotate together, the wheel can travel forwards, and through control over the driving motor frequency converter, the speed of the wheel can be controlled as well. According to the spherical motor-driven wheel capable of being driven by the four wheels, electric energy is used as a power source, environmental protection can be better achieved, meanwhile, a traditional drive system is removed, and the efficiency of mechanical transmission is improved.
Description
Technical field
The utility model relates to a kind of spherical electric vehicle wheel that can realize four wheel drive, belongs to the electromechanical integration field.
Background technology
Existing most of automobiles adopt driving engine that power is provided, and fuel gasoline or diesel oil are faced with energy shock, and simultaneously, the tail gas of engine emission has caused pollution to atmosphere, along with people's environmental protection consciousness progressively strengthens, must seek the alternative energy.The power that driving engine sends passes on the drive wheel through driving system, drives running car.Because driving system is made up of a plurality of mechanisms such as change-speed box, transmission shaft, drive axles, and there is mechanical wear in the process of each mechanism's transferring power, so reduced energy utilization ratio.At present, battery-driven car more and more is subjected to people's welcome as unique self-propelled vehicle that can reach zero-emission, and the electric wheel technology becomes an important developing direction of battery-driven car.But existing electric wheel adopts DC motor more, because big, the frequent start-stop inconvenience of its rotor inertia, price are expensive, has limited its development.
Summary of the invention
In view of this, the utility model is to provide a kind of electric energy of using as propulsion source, simultaneously the spherical electric vehicle wheel that directly drives with alternating-current motor/AC motor.Specifically be achieved through the following technical solutions:
A kind of spherical electric vehicle wheel that can realize four wheel drive, comprise drive motor, wireless power transmission system receiving end, drive motor frequency converter, spoke, wheel rim, tire, wireless power transmission system transmitting terminal, described wireless power transmission system receiving end, drive motor frequency converter, drive motor are positioned on the horizontal axis of spherical electric vehicle wheel, wherein drive motor adopts alternating-current motor/AC motor, and outer rotor links to each other with wheel rim by spoke.
The utility model is the advantage of prior art relatively:
(1) power directly is sent on the wheel from electrical motor, has saved traditional driving system, has improved the weight that powerdriven efficient has also alleviated car load simultaneously.
(2) adopt electric energy as propulsion source, help to alleviate current crisis of resource.
(3) adopt electric energy as propulsion source, eliminated emission of automobile wastes, be conducive to environmental protection, alleviate atmospheric contamination.
(4) adopt the electric wheel technology, under the situation of same power demand, can give a plurality of electrical motors with the single electric motor power division, reduced the electric and requirements mechanical drive parts, be convenient to design and produce.
Description of drawings
Fig. 1 is a kind of spherical electric vehicle wheel scheme drawing that can realize four wheel drive described in the utility model.
Fig. 2 is the transmission route scheme drawing of propulsive effort in the background technology.
The specific embodiment
1-drive motor; 2-wireless power transmission system receiving end; 3-drive motor frequency converter; 4-spoke; 5-wheel rim; 6-tire; 7-wireless power transmission system transmitting terminal.
The utility model is described in further detail below in conjunction with example figure.
As shown in Figure 1, 2, a kind of spherical electric vehicle wheel that can realize four wheel drive described in the utility model comprises drive motor 1, wireless power transmission system receiving end 2, drive motor frequency converter 3, spoke 4, wheel rim 5, tire 6, wireless power transmission system transmitting terminal 7.Described wireless power transmission system receiving end 2, drive motor frequency converter 3, drive motor 1 are positioned on the horizontal axis of spherical electric vehicle wheel, and wherein drive motor 1 adopts alternating-current motor/AC motor, and outer rotor links to each other with wheel rim 5 by spoke 4.
Wireless power transmission system transmitting terminal 7 is transformed into electromagnetic wave signal to electric signal, after modulation is amplified, launch with certain amplitude and frequency, after the sheath reflection, received by wireless power transmission system receiving end 2, wireless power transmission system receiving end 2 utilizes electromagnetic switching device that the electromagnetic wave that receives is converted into ac signal, alternating current passes through after the frequency control of drive motor frequency converter 3 again, for drive motor 1 provides electric current, drive motor 1 outer rotor obtains to rotate behind the electric energy, drives wheel rim 5 by spoke 4 and rotates together, and the spherical electric vehicle wheel is moved ahead, by the adjusting to drive motor frequency converter 3, can also realize the control to wheel velocity.
The above is preferred embodiments of the present utility model only, is not for limiting protection domain of the present utility model.All any modifications of making within spirit of the present utility model and principle are equal to be replaced and improves, and all should be included within the protection domain of the present utility model.
