Among the figure: 1, the body of driving engine, 2, the bent axle of driving engine, 3, the stator of electrical generator, 4, the rotor of electrical generator; 5, the shell of electrical motor, 6, the stator of electrical motor, 7, the rotor of electrical motor, 8, the axle of electrical motor; 9, bearing, 10, reductor or change-speed box, 11, flywheel.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
Embodiment 1:
See also Fig. 1, a kind of one stroke-increasing electric automobile drives assembly, comprises the coaxial driving engine that sets gradually, electrical generator and electrical motor;
The bent axle 2 of driving engine is provided with the cantilever segment that extends near the electrical generator direction; The rotor 4 of electrical generator is fixed on this cantilever segment; The shell 5 of electrical motor is provided with the extension of extending near the driving engine direction; The stator 3 of electrical generator is fixed on this extension; The shell 5 of electrical motor is affixed with the shell 1 of driving engine.
Present embodiment uses two cylinder liquid-cooled engines to do to increase journey system dynamic source, replaces engine flywheels with generator amature 4 again, changes to front of the engine with former at the rotating speed, the phase detector that utilize flywheel teeth to obtain signal.Adopt the double starter of making driving engine of magneto alternator generating.The stator 3 of electrical generator and the stator 6 of electrical motor are installed on the shell 5 of electrical motor, guarantee setting accuracy, bolted connection by locating dowel pin between the shell 5 of electrical motor and the body 1 of driving engine.Design Coolant gallery on the shell 5 of electrical motor, simultaneously the stator 6 of cool motors and the stator 3 of electrical generator.Electrical motor rotor 7 be packed on the axle 8 of electrical motor, axle 8 the two ends of electrical motor are provided with backup bearing 9, the shell 5 back direct mount reductor or the change-speed boxs 10 of electrical motor.Above-mentioned driving assembly is installed simply because of compact conformation, can be directly installed on forward engine room, substitutes the position of driving engine.
Above-mentioned driving assembly, engine crankshaft axis, generator amature axis, motor rotor axis overlap; Generator amature is fixed on the engine crankshaft, and because of engine crankshaft has enough bearings, so bearing support structure can be no longer designed in the electrical generator outside, promptly the rotor of electrical generator is fixed on the cantilever segment of engine crankshaft; The stator of electrical generator is fixed on the shell of electrical motor; Electrical generator assembly relation rotor is attached to two different parts respectively with stator; The stator of electrical generator need have identical radiating condition with the stator of electrical motor; So motor casing to extending near a side of driving engine, is fixed on the stator of electrical generator on the shell extension of electrical motor, shares cooling structure with electrical motor; Electrical generator does not link to each other with motor rotor shaft.Driving engine, electrical generator and three power machines of electrical motor only need two axles and two bodies or shell like this; The shared axle of driving engine and electrical generator; The shared shell of electrical generator and electrical motor has been saved an axle, a coupler and a shell from structure.Traditional scheme need use a coupler between driving engine and electrical generator.
