Description
Technical field
The present invention relates to electrical automobile two gear mechanical transmissions, especially a kind of two gear automatic speed changer for machine used for electric vehicle.
Background technique
Automobile is the traffic tool that the mankind are indispensable, but day by day seriously weighing along with environmental pollution, the continuous minimizing of non-renewable resources, develops the inevitable choice that energy-conservation and new-energy automobile has become countries in the world.Current, the emphasis of China advances pure electric automobile and plug-in hybrid-power automobile industrialization, to promote China's automobile industry overall technology level.
Wherein, the speed change scheme that power system of electric automobile adopts mainly contains following three kinds:
Scheme one adopts fixing reduction speed ratio, relies on motor to realize the task of speed change completely.According to the characteristic curve of motor, fixing reduction speed ratio is operated in high efficiency range while being difficult to make motor ensure power performance, cause start, low speed time electric current large, power consumption is high, and climb unable, high speed motive force is poor, owing to there is no neutral position, for the motor of part noenergy feedback, when can cause descending, electric power generation is to controller recoil electricity, and controller is damaged.
Scheme two is the speed variator systems adopting conventional fuel oil car.Because motor has between high efficient area comparatively wide relative to internal-combustion engine itself, conventional transmissions generally has four to six gears, seems waste one's talent on a petty job for pure electric automobile, and make structure become complicated, cost raises simultaneously.
Scheme three is employing two speed transmissions; Use big retarding ratio during low speed driving, realize good starting performance, when running at high speed, use little reduction speed ratio, meet the requirement of the max speed.Due to the rationality of the program, a lot of people has done successful exploration in this respect.Result for retrieval so that following table one is related invention:

Patent 1 and 7 adopts fluid torque converter to coordinate fixing reduction speed ratio or planetary gears to provide wider speed change to make up the deficiency of single speed ratio, but the poor efficiency of fluid torque converter itself and labyrinth hinder its extensive use.
The switching of what patent 2 adopted is hydraulic pressure installation control realization height gear, the complexity of hydraulic system itself and the requirement to sealing, gear shifting force size adjustment difficulty etc. makes its advantage be not so good as electric gear shifting mechanism.
Patent 4 realizes parking braking for automotive dynamoelectric machine formula speed changer, proposes a kind of new departure.
Patent 3 adopts simple planetary arrangement to realize two gears switchings, and patent 5 provides the multiple clutch of a kind of employing, is separated by it scheme that adhesive realizes gear shift.Such scheme all needs to complete gear shifting action by hydraulic control system.Patent 6 discloses a kind of second gear automatic speed changer for machine with dry clutch, and clutch is different with traditional arrangement form.Operated clutch and combined cover can realize power and not interrupt gear shift.Active friction plate, driven friction disk and clutch compressing disc is had in the clutch assembly that automatic transmission disclosed in patent 8 adopts, by the combination of magnet control active friction plate and driven friction disk be separated, drive shift fork by stepper motor and then drive synchronizer clutch collar to carry out the automatic switchover of gear.Such scheme all causes system architecture complexity to be increased, and controls difficulty and strengthens.
Summary of the invention
For two gear mechanical transmissions used for electric vehicle, the present invention proposes a kind of two gear machineries used for electric vehicle
automaticallyspeed changer, only arranges height two gears, does not have setting to reverse gear without the need to block selecting device, cancel clutch, utilize electric powered motor motor to coordinate speed governing to complete gearshift synchronous, arrange an automatic controller and realize self shifter.The present invention on guarantee vehicle correlated performance basis, can realize speed changer structure and simplifies most, reduce vehicle cost and deadweight.
Technical conceive: only need height two gears for two gear mechanical transmissions itself used for electric vehicle, utilize motor reversal can realize vehicle backing to traveling, speed changer is without the need to reversing gear, therefore its needs arrange shift control apparatus and without the need to block selecting device.
