Description

A kind of electric vehicles hydromechanical transmission
Technical field
The invention belongs to the elec. vehicle technical field, particularly relate to a kind of electric vehicles hydromechanical transmission.
Background technology
At present, low-carbon (LC), environmental protection new forms of energy power technology are just in the ascendant in the application of system of vehicle transmission, and the exploitation electronlmobil has become trend and direction.The life-span, charging ability and the use cost that improve battery are very important.The starting current of known motor very high as: the starting current of alternating current dynamo is that 4~7 times of rated current, the starting current of DC machine are 8~15 times of rated current.This must cause the increase of accumulator cell assembly quantity.This becomes a burden of automobile again not need unnecessary storage battery during normal the operation, reduces its operation ability.Adopt Hi cell as: its cost of lithium cell has increased again a lot.How to realize that No Load Start just becomes the gordian technique of dealing with problems.
Summary of the invention
The present invention provides a kind of electric vehicles hydromechanical transmission for solving the technical matters that exists in the known technology.
The purpose of this invention is to provide and a kind ofly have good vehicle launch performance, realize that zero moment of torsion of motor starts, starting current low, transmission is efficient, and is energy-conservation, in light weight, the electric vehicles hydromechanical transmission of characteristics such as carrying capacity height.
The tor-con input torque is the pump impeller moment of torsion and its rotating speed (M=kn that square is directly proportional 2), except that the inertia torque of rotor and pump impeller, the motor output torque is zero to be desirable No Load Start during startup.
Electric vehicles hydromechanical transmission of the present invention is made up of vehicle transmission devices such as accumulator cell assembly, electrical motor, electric machine controller, the converter coupling with lockup clutch, Powershift transmission, drive axles.Electrical motor zero moment of torsion starting drives transmission devices such as turbine transformer, change speed gear box, drive axle and realizes the system of vehicle transmission function.The effect of turbine transformer can realize the No Load Start of motor; Reduce the carry that starting current reduces accumulator cell assembly greatly, the deadweight that reduce accumulator cell assembly quantity 3/2/3rds~four according to a preliminary estimate, alleviates vehicle greatly improves the payload capability of vehicle.Owing to adopt hydraulic transmission to make vehicle have characteristics such as favorable starting performance, adaptivity.
The technical scheme that electric vehicles hydromechanical transmission of the present invention is taked for the technical matters that exists in the solution known technology is:
A kind of electric vehicles hydromechanical transmission; Be characterized in: hydromechanical transmission comprises battery pack, electrical motor, electric machine controller, turbine transformer, Powershift transmission; Battery pack is supplied power to electrical motor; Motor controller controls direct motor drive turbine transformer, turbine transformer connects Powershift transmission, carries out the vehicle hydraulic mechanical drive.
Electric vehicles hydromechanical transmission of the present invention can also be taked following technical scheme:
Described electric vehicles hydromechanical transmission is characterized in: turbine transformer is the converter coupling with lockup clutch.
Described electric vehicles hydromechanical transmission is characterized in: Powershift transmission connects drive axle and carries out the vehicle hydraulic mechanical drive.
Advantage and good effect that the present invention has are:
The electric vehicles hydromechanical transmission is owing to adopted brand-new technology scheme of the present invention; Compared with prior art; Electric vehicles hydromechanical drive mode of the present invention, the too high problem of electric current in order to solve electronlmobil and to start exactly, the effect of turbine transformer can realize the No Load Start of motor; Reduce starting current, reduce the payload capability that the carry of accumulator cell assembly, the deadweight that alleviates vehicle improve vehicle greatly; Adopt hydraulic transmission to make vehicle have advantages such as favorable starting performance, adaptivity.
The invention belongs to the application of low-carbon (LC), environmental protection new forms of energy power technology, emission abatement, protection environment in system of vehicle transmission.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the turbine transformer structural representation.
Among the figure, the 1-battery pack; The 2-electric machine controller; The 3-electrical motor; 4-have a converter coupling of lockup clutch; 5-power shfit gear case.
The specific embodiment
For further understanding technology contents of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
Consult accompanying drawing 1 and Fig. 2.
Embodiment 1
A kind of electric vehicles hydromechanical transmission; Comprise battery pack 1, electrical motor 3, electric machine controller 2, converter coupling 4, Powershift transmission 5 with lockup clutch; Electrical motor 3 is given in battery pack 1 power supply; Electric machine controller 2 control motors 3 drive the converter coupling 4 with lockup clutch; Converter coupling 4 with lockup clutch connects Powershift transmission 5, and Powershift transmission 5 connects drive axle and carries out the vehicle hydraulic mechanical drive, realizes the walking of vehicle.
Usually, motor has the electric current of the startup of carrying very high.This must cause the increase of accumulator cell assembly quantity.This becomes a burden of automobile again not need unnecessary storage battery during normal the operation, reduces its operation ability; The use cost of battery also increases.
The tor-con input torque is the pump impeller moment of torsion and its rotating speed (M=kn that square is directly proportional 2), except that the inertia torque of rotor and pump impeller, the motor output torque is zero to be desirable No Load Start during startup; The effect of turbine transformer can realize the No Load Start of motor; Reduce the carry that starting current reduces accumulator cell assembly greatly, the deadweight that reduce accumulator cell assembly quantity 3/2/3rds~four according to a preliminary estimate, alleviates vehicle greatly improves the payload capability of vehicle.
Adopt hydromechanical drive to make vehicle have the advantage of hydraulic transmission.As: favorable starting performance, adaptivity etc.
