Description
Technical field:
The utility model belongs to the actuating motor field, particularly a kind of disc type starting-generating all-in-one.
Background technology:
Existing vehicle electrical starting all has two motors, and actuating motor is installed in the engine flywheel dish outside, and generator is installed in the motor head fan side; During engine start, battery supply is supplied power to actuating motor, and actuating motor output is connected with a joggle with the engine flywheel dish behind decelerator, isolator, drives the engine running ignition start with big torque, the slow-speed of revolution.After the engine start, isolator works, and actuating motor breaks away from the engine flywheel dish, and the actuating motor dead electricity quits work; Engine drives the generator generating that runs up through belt pulley simultaneously, supplies power to battery, power consumption equipment.Engine and generator be running simultaneously always, and actuating motor is only in the instantaneous use of engine start, and driving process is to leave unused.How to merge actuating motor and generator in one, industry also has many conceptions, but all undesirable, can't commercialization, trace it to its cause,
Require during engine start: the motor slow-speed of revolution (hundreds of rev/min) high pulling torque (hundreds of ox rice), more high-power (several kilowatts) short time (a few second);
Require during engine power generation: the high rotating speed of motor (several thousand change) little moment of torsion (tens Ns of rice), smaller power (a few hectowatt) long-time (several hours).
Satisfy above-mentioned requirements, cooperating between engine and motor: when starting, the motor back of slowing down drives engine; When generate electricity in the starting back, the engine drives motor is with speed or speedup running.
Under this specific (special) requirements, occur: the one of which selection of Motor is unreasonable, so that volume is big, can't in former having living space, install; Its two speed changer and isolator merge design, can't satisfy the big speed change of actuating motor, big torque drives engine, and can not make electric efficiency not high with the moving actuating motor generating of speed belt after the engine start, can not satisfy need for electricity.
Therefore, the demands of different that two species diversity are bigger is to be difficult to satisfy with a motor.
Summary of the invention:
The purpose of the utility model is design a kind of employings disc type electric machine, exports big torque through a planet decelerator, both work as actuating motor, again can with engine with the fast disc type starting-generating all-in-one that generates electricity.
