Abstract
The utility model relates to an electric power torque converter, which is composed of a driving rotor, a stator and a driven rotor, wherein the driving rotor, the stator and the driven rotor are all axially arranged, and the stator adopts an open type magnetic circuit structure. A magnetic force line sets out from the N pole of the driving rotor, and reaches the driven rotor after penetrating through an open type stator armature, and then returns to the S pole of the driving rotor through the open type stator armature, and thereby a closed of the magnetic circuit is formed. By adjusting electric current of the stator, the magnetic flux density of the air gap of the driven rotor can be changed, and thereby the output torque of the driven rotor is changed. The torque converter is especially suitable for the transmission systems driven by the hybrid power vehicles and other internal-combustion engines.
Description
Affiliated technical field
The utility model relates to a kind ofly can change Prime mover torque, thereby improves the electric power torque-converters of prime mover driven ability, is particularly useful for hybrid vehicle and other oil-engine driven drive systems.
Background technology
At present, internal combustion engine generally exports moment of torsion to drive system by following several modes: clutch, hydraulic torque converter, electric drive system etc.
Clutch is made up of clutch plate, platen and separating mechanism.By separating mechanism, rely on the friction between internal combustion engine flywheel and the clutch plate, make internal combustion engine and drive system temporarily separate and engage gradually, to cut off or to transmit the power output of internal combustion engine.Use clutch, the output torque of internal combustion engine can not change.In the process of clutch separation and joint, cause the moment of torsion sudden change of drive system easily, cause the vibration and the impact of drive system, therefore the operation to clutch linkage requires very high.
Hydraulic torque converter is made up of pump impeller, turbine, guide wheel and working solution.Pump impeller links to each other with internal combustion engine, rotates in working solution, and working solution is outwards moved by the axle center of pump impeller under action of centrifugal force, forms powerful eddy current, thereby promotes the turbine rotation.Turbine links to each other with drive system and carries out power output.Because use the fluid power carry-over moment, the energy loss of hydraulic torque converter is bigger; Transmission of power also has sluggishness, although adopted lock-up clutch now, sluggishness the during slow-speed of revolution and poor efficiency still can't be avoided.
Electric drive system is by a generator that is installed on the internal combustion engine flywheel, and motor and control system that one (or a plurality of) are installed on the drive system are formed.The power of internal combustion engine under the control of control system, flows to motor by generator for electricity generation, and motor is delivered to drive system after converting electric energy to mechanical energy.Owing to do not have mechanical connection between internal combustion engine and the drive system, do not have positive connection between internal-combustion engine rotational speed and the drive system rotating speed, so internal combustion engine can be operated in more efficiently on the working point.But electric drive system more complicated, energy through twice conversion (mechanical energy converts electric energy to, and electric energy converts mechanical energy to) after, efficient reduces.
Summary of the invention
In order to overcome the deficiency of the existing various kinds of drive, the utility model provides a kind of electric power torque-converters.It utilizes the magnetic field coupling based on the principle of electric drive system, and passes through the excitation effect of electric current, reaches the effect that changes output torque.Simultaneously do not have mechanical connection between the input and output of the present utility model, thereby improved the east that shakes of the impact in the transmission process.
The technical scheme that its technical problem that solves the utility model adopts is: in electric drive system, generator and motor all adopt the axial magnetic field structure, and has an identical radial dimension, thereby the stator of generator and motor is close together forms a stator, and the employing Open architecture, just constituted electric power torque-converters of the present utility model.Therefore the utility model is made of power rotor, open stator and passive rotor 3 elements.Power rotor drives the passive rotor rotation by the mode of magnetic field coupling, adjusts the size of stator current, just can change the magnetic flux density of passive rotor air gap, has therefore changed the output torque of passive rotor.When power rotor and passive rotor remained static simultaneously, the excitation effect by stator current produced rotating magnetic field on stator, drove power rotor and passive rotor and rotated simultaneously.
The beneficial effects of the utility model are, generator in the electric drive system and motor are combined, and are simple in structure; By the direct coupling in magnetic field, avoided the secondary conversion of energy, improved transmission efficiency; The excitation effect of stator current has changed the output torque of prime mover, has improved the driving force of prime mover.
