Description

Distribution type differential mixed composite driving system

The present invention relates to kind of a distribution type differential mixed composite driving system.

The energy and noise pollution in recent years is on the rise, and the contamination level of driven by power carrier is lower, so can alleviate above-mentioned problem; But all the time, the research of electric carrier and development can't obtain big voyage because of the limitation that is subjected to the storage battery capacity, if desire by increasing storage battery volume and quantity to overcome this problem, relatively also can increase the weight of carrier own and expend more electric energy, do not conform to economy, so before the storage battery technical matters did not obtain important breakthrough, comparatively Shi Yong type of drive was for adopting the design of compound drive configuration, what be developed at present includes:

(A) the power serial power is hybrid: this kind pattern is the most typical structural shape of composite electric automobile, it is to produce electric energy by the engine driven power generator machine storage battery is charged, power to CD-ROM drive motor to drive vehicle by storage battery again, but the energy net effciency of this mode is on the low side, the GMHX3 that delivers as General Motors;

(B) synchronous close coupled type: be rotating shaft, vehicle produced drive and control fast acting on again, as the VWCHICO of the national automobile of Germany with the direct series combination CD-ROM drive motor of engine power output shaft mat power-transfer clutch.

Engine described in above-mentioned (B) and motor only can be selected one of them and do the output driving and can't rate of doing work addition.

The object of the invention provides a kind of distribution type differential mixed composite driving system, to solve above-mentioned prior art problems.

Disclosed distribution type differential mixed composite driving system, the horsepower output that it is characterized in that mat engine (or other rotating power source) output shaft is except that driving the leading portion load for controlling, and in conjunction with a differential hybrid drive to drive the latter end load, the group of motors of this differential hybrid drive system is by exchanging or DC brush formula or group of motors that brushless motor constituted are formed with the differential wheels of three-end axle in conjunction with transmission, its structure comprises one group of differential gear structure that is three-end axle, wherein have two groups of differential output shafts and one group of input shaft is coupled in electric machine through driving gear set, and the wheel shaft of two groups of differential gears is coupled in the transmission that driven from rotary power unit, master end respectively with axis and through the input shaft of Clutch Coupling in the rear end differential gear box, to drive the latter end load that both sides can be differential; Above-mentioned three-end axle differential gear can be replaced by the planetary gear group, and gear cluster also can be replaced by friction wheel; Be provided with drg between its rotor of above-mentioned group of motors and stator, drg is also accepted controlling of actuation means and produce the motor-driven function when received current; Or mat external force affects do generating output; This design can add engine to the output of latter end load and the addition of the output rate of doing work and the speed order of group of motors, and its additive process is not influenced by both length velocity relations; Generally speaking the cumulative volume of system is less, save cost and space, group of motors can be accepted the control of actuation means, start engine and when received current, produce the direct motor drive function for driving leading portion load or back loading or driving simultaneously or conduct, or when accepting the input of engine rotary kinetic energy and between load, form speed discrepancy and the output of doing to generate electricity, and the mat outgoing current forms the differential adjustment function that the generation of coupling moment of torsion can be controlled speed change, or as regenerative electric power braking, particularly when being the driving of active force with the engine, speed discrepancy between three-end axle differential gear set two differential shafts in the differential hybrid drive structure of mat charges to accumulator jar with the traction motor group, and control its charging current size can obtain adjust and load between speed discrepancy, and engine because of can be the constant speed degree or only modulation part rotating speed to keep on the go in higher running efficiency and more oligosaprobic work area, and produce differential output via differential hybrid drive, therefore can in the low speed segment variable speed drive (VSD), promote engine efficiency and reduce pollution, acquisition is to the accumulator jar rechargeable electrical energy and do the coupling of variable-ratio, also can be used as in addition CD-ROM drive motor with independent do rotation output to drive load or to rotate the driving load simultaneously with engine.

Group of motors U101: be provided with drg B103 between its rotor and stator, B103 also accepts the controlling for providing the rotor of direct group of motors U101 and stator to do mechanicalness genlocing in controlling of central controller CCU101; Above-mentioned group of motors U101 serve as reasons interchange or brush DC or have brush electric machine structure to constitute, particularly suitable has interchange or the DC brush or the brushless motor of healing motor characteristic series excitation that little speed heals high or helping the compounding type to constitute maybe can to control (containing constant current controls) as current value with load, for the value added torsion that produce to assist drives load, and the driving of accepting driving circuit D101 is controlled;

Driving circuit device D101 is controlled by the instruction of controlling of accepting central controller CCU101 between group of motors U101 and accumulator jar BT101, can drive motor group U101 as the actuator of motor or as electric current and voltage regulator so that group of motors U101 export to the storage battery charging or to other loads output electric energy or the generating that is controllable current as electric motors function;

Central controller CCU101 then makes according to the operating state of operator's operating order and rotary motive power unit, master end P101 and controls instruction accordingly and it is transported to driving circuit device D101;

The differential output end axle of differential hybrid drive M101 and for the binding side of power-transfer clutch CL104 between coupling rear end differential gear box further can add on demand and casing between drg B102, be provided as drive the front end load start engine or do static in generating with by driven by engine group of motors U101 as generator function to the storage battery charging or to other electric; If during as the alternative electric generation output function, its U101 selects the group of motors with alternative electric generation function for use, contain the frequency conversion drive type electric machine that is provided with permanent magnetism or winding excitation type magnetic pole, or same armature loop be provided with simultaneously be made for exchange the output conducting ring and be made for direct current output/input commutator brush commutating machine device arranged, it exchanges output and can be indefinite frequency output or the control of mat engine constant speed and make fixed frequency and export;

Above-mentioned direct drive load and differential distribution load comprise by the rotary motive power source of containing a group or more, a group or more direct drive load, a group or more differential hybrid drive M101 and the compound cascaded structure of expansion kenel of the load group work that drives order series combination.
