The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing and example.
Principle of work scheme drawing of the present invention as shown in Figure 1, driving engine is input to mechanical energy in the double-rotor machine by axle, motor is input to energy in the magnetic force stepless transmission again.Simultaneously, coil cutting magnetic induction line generation current in the double-rotor machine, twice conversion of electric current by inverter is input in the coil winding of magnetic force stepless transmission so that according to the speed ratio of the different operating conditions change-speed boxs of driving engine, meanwhile can be as required with a part of electrical power storage in battery, this part energy can be when needed, such as the vehicle accelerating mode, be input in the magnetic force stepless transmission.When with the transmission shaft between double-rotor machine and the magnetic gear shift fixedly the time, the energy of car brakeing can be input in the battery through magnetic gear shift, and system plays the effect that energy reclaims.
Motor type seemingly in double-rotor machine among the present invention part and the cascade adjustable-speed system, different is, utilized electrical motor in the cascade adjustable-speed system not have the air gap torque part that adopts among the present invention, stator in the former cascade adjustable-speed system is directly linked to each other with the input end of magnetic force stepless transmission, this kind design can ensure more power moment of torsion and pass to the change-speed box part, and the power of driving engine output has obtained sufficient application.
The basis of the magnetic force stepless transmission among the present invention (Fig. 8) is magnetic gear (Fig. 2), because it adopts non-contacting method transmitting torque, can eliminate the loss that produces owing to friction, improve transmission efficiency, have than big speed ratio, reduced simultaneously the noise that produces in the operational process, and owing to do not use lubricating oil, made it more be convenient to safeguard.
The magnetic gear is comprised of internal rotor (Fig. 3), adjustable magnetic rotor (Fig. 4), outer rotor (Fig. 5) three parts, but the coaxial each other no touch of three parts leaves the gap of 1mm.Wherein inner and outer rotors is made at yoke by binding by block permanent magnet, but the permanent magnet number on the internal rotor will be less than the permanent magnet number on the outer rotor, has certain transmitting ratio when only in this way guarantee magnetic gear moves.Spaced apart by the cold rolling adjustable magnetic piece that forms of silicon steel plate in the adjustable magnetic rotor in the middle of the inner and outer rotors, its effect is to be adjusted in the magnetic field between internal rotor and outer rotor and to set up magnetic circuit.Generally, internal rotor links to each other with input shaft, and adjustable magnetic rotor and outer rotor have one to maintain static, and another links to each other with output shaft.When internal rotor rotated, the magnetic field of its generation and other rotor interacted, so owing to produced a fixing transmitting ratio between the strength difference input shaft in magnetic field and the output shaft.Magnetic force stepless transmission develops on this basis exactly, different is, the novel magnetic toric transmission with the outer rotor of magnetic gear as control rotor (Fig. 6), permanent magnet all is equipped with in the outside in the rotor yoke iron, and coil winding (Fig. 7) is added in the outside of outer rotor, simultaneously with the adjustable magnetic rotor as output, the rotating speed by control magnet coil winding and then control outer rotor makes between internal rotor and the adjustable magnetic rotor and can have continuous transmitting ratio, namely reaches infinite variable speed purpose.The output torque of this novel magnetic toric transmission can maintain about 100Nm, and driving efficiency can be up to 98%, and this novel magnetic toric transmission has larger transmitting ratio, and maximum transmission ratio can reach 10:1, can substitute the main reduction gear on the automobile.
The present invention realizes that the main process of hybrid power transmission is as follows:
Engine operation, mechanical energy is input to magnetic force stepless transmission by double-rotor machine through transmission shaft on the one hand, as the propulsion source of change-speed box; In double-rotor machine, produce on the one hand inducing current, be input in the coil winding of magnetic force stepless transmission through the inverter frequency conversion and change in order to carry out speed ratio according to Under Different Work Condition of Engine control change-speed box, meanwhile, can in battery, store a part of electric energy as required.
Engine operation, mechanical energy is input in the magnetic force stepless transmission through transmission shaft by double-rotor machine on the one hand, another part produces inducing current in double-rotor machine, by brush electric current is drawn, be input in the coil winding of magnetic force stepless transmission so that carrying out speed ratio according to Under Different Work Condition of Engine control change-speed box changes through the inverter frequency conversion, battery provides electric energy to magnetic force stepless transmission simultaneously.The effect of the existing deceleration of magnetic force stepless transmission of this moment also has the effect of electrical motor.
Engine stop work is fixed double-rotor machine with the transmission shaft between the magnetic gear shift, the kinetic energy that braking is reclaimed changes into electrical power storage in battery through magnetic force stepless transmission.
Above institute gives an actual example and only is preferred embodiment of the present invention, and the simple equivalence of generally doing according to claim of the present invention and description of the invention content changes and modifies, and all should belong to the scope that patent of the present invention covers.
