Background technique
Electric vehicle receives increasing concern as the new-energy automobile of environmental protection, and its product category is also more and more abundanter.The transmission system that fixed stop joined by high-speed electric expreess locomotive has operationally steadily, the advantage of power failure-free, but the single fixed stop that existing electric vehicle adopts is unfavorable for drive motor efficiency operation, and higher to the performance requirement of motor.In addition, the transmission system of fixed stop joined by high-speed electric expreess locomotive, and its parallel-axis type speed variator volume is comparatively large, is unfavorable for assembling; It adopts synchronizer to there will be the problem such as power interruption, shift shock as gear shifting actuating mechanism, and on rotary component, adopt hydraulic coupling and break to be difficult to avoid there will be Leakage.
Summary of the invention
In view of this, the object of this invention is to provide a kind of single planetary row two-shift automatic speed variator used for electric vehicle, can effectively solve the problem.
The object of the invention is to be achieved through the following technical solutions:
A kind of single planetary row two-shift automatic speed variator used for electric vehicle, comprise casing, the driving gear be connected with drive motor is provided with in described casing, the driven gear engaged with driving gear and the jack shaft be connected with driven gear, described jack shaft is also provided with planetary gears, described planetary gears comprises the sun gear be connected on jack shaft, the planet wheel engaged with sun gear, planet wheel retainer and the gear ring engaged with planet wheel, described planet wheel retainer is provided with output shaft, clutch is provided with between described output shaft and sun gear or jack shaft, described casing is also provided with the break for braking gear ring.
Further, described jack shaft is hollow shaft, and described casing is provided with the back shaft for supporting hollow shaft, described jack shaft is located on back shaft by bearing housing.
Further, the bearing between described jack shaft and back shaft adopts needle bearing.
Further, also bearing is provided with between the outer wall of described jack shaft and casing.
Further, described back shaft is also set to hollow-core construction.
Further, described clutch is magnetic clutch, and described break is electromagnetic brake.
The invention has the beneficial effects as follows: single planetary row two-shift automatic speed variator used for electric vehicle of the present invention, break is adopted to add the means of clutch collocation single planetary row two shift transmission, can reduce drive motor performance requirement, improve the operational efficiency of motor, increase the continual mileage of electric motor car.Adopt the state of clutch and break to switch and realize gear change, electric motor car gearshift power failure-free can be realized, reduce shift shock degree.When clutch combination, break separate, now speed changer is in two gears and puts, drive motor power is directly passed to speed changer planet wheel retainer output shaft from sun gear by clutch, and this power train process eliminates gears meshing power transmission, adds the working life of gear.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from the practice of the present invention.Target of the present invention and other advantages can be realized by specification below and obtain.
