Outside, transmission system of the high-speed electric expreess locomotive with fixed gear, its parallel-axis type speed variator volume is larger, is unfavorable for assembling；It uses synchronization
The problems such as power interruption, shift shock occurs as gear shifting actuating mechanism in device, and hydraulic clutch is used on rotary part
It is difficult to avoid that with brake and Leakage occurs.
The content of the invention
In view of this, it is an object of the invention to provide a kind of single planetary row two-shift automatic speed variator used for electric vehicle, can have
Effect solves the above problems.
The purpose of the present invention is achieved through the following technical solutions：
It is provided with and drives in a kind of single planetary row two-shift automatic speed variator used for electric vehicle, including casing, the casing
The connected driving gear of motor, the driven gear engaged with driving gear and the jackshaft connected with driven gear, it is described in
Planetary gears is additionally provided with countershaft, the planetary gears includes the sun gear and the sun being connected on jackshaft
It is provided with the planetary gear of wheel engagement, planetary gear retainer and the gear ring engaged with planetary gear, the planetary gear retainer defeated
Shaft, is provided with clutch, the casing between the output shaft and sun gear or jackshaft and is additionally provided with for brake tooth
The brake of circle.
Further, the jackshaft is that the support shaft for supporting hollow shaft is provided with hollow shaft, the casing, described
Jackshaft is set in support shaft by bearing.
Further, the bearing between the jackshaft and support shaft uses needle bearing.
Further, it is also equipped with bearing between the outer wall and casing of the jackshaft.
Further, the support shaft is also configured as hollow-core construction.
Further, the clutch is electromagnetic clutch, and the brake is electromagnetic brake.
The beneficial effects of the invention are as follows：The single planetary row two-shift automatic speed variator used for electric vehicle of the present invention, using braking
Device adds the means of the clutch collocation shift transmission of single planetary row two, can reduce to motor performance requirement, improve motor
Operational efficiency, increases the continual mileage of electric car.Realize that gear changes using the state switching of clutch and brake, Ke Yishi
Existing electric car gearshift power failure-free, reduction shift shock degree.When clutch combination, brake are separated, now speed changer is in
Two gears are put, and motor power is passed directly on speed changer planetary gear retainer output shaft from sun gear by clutch, this
Individual power train process eliminates gear engagement power transmission, adds the service life of gear.
Other advantages, target and the feature of the present invention will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.The present invention target and other advantages can be realized by following specification and
Obtain.
