Abstract
The invention provides a power assembly for a two-shift motor vehicle. A driving motor is integrally connected with a two-shift transmission so as to form a modularized power assembly which is simple to assemble and maintain. The transmission of the power assembly is a speed-change mechanism with two working shifts, namely a low-speed shift and a high-speed shift. The vehicle runs by using the low-speed shift while climbing under a heavy load and runs by using the high-speed shift while running on smooth road surface under a light road. The speed-change mechanism is implemented by using a synchronizer on a second shaft, and is jointed with a low-speed or a high-speed driven gear respectively through the synchronizer so as to realize low-speed and high-speed operations. The power assembly for the two-shift motor vehicle has a compact structure and flexible and convenient operation, and can reduce rated power for driving the motor.
Description
Technical field
The present invention is suitable for a kind of power assembly for two-shift motor vehicle of electrocar, the driving of electronic passenger and freight car.
Background technology
Vehicle technology has obtained certain development as green energy resource, general battery-driven car all is to adopt directly to drive or permanent transmitting ratio, realizes vehicular drive by electric machine speed regulation, like this can be higher to the demanded power output of motor; And very flexible is not easy to assembling and maintenance.Thereby, adopt the mechanical type gear shift can reduce the rating horsepower that uses motor.
Summary of the invention
The objective of the invention is to solve above-mentioned existing existing problem, provide a kind of alerting ability good, be easy to a kind of power assembly for two-shift motor vehicle that assembles and keep in repair.
The present invention is achieved in that the front end cover of drive motor and mission case adopts bolted connection, the front end cover of mission case, rear side housing adopt bolted connection to constitute mission case, by the bearing installation input shaft, the output shaft of drive motor is connected with the input shaft of change-speed box; Low-speed active gear, high speed driving gear are installed on the input shaft,, are gone up for two mileage output driving gear, high speed driven gear, synchro, low speed driven gear, main deceleration driving gear are installed by two of bearing installations; Synchro is installed selector fork by declutch shift shaft, and selector fork connects driving lever, and driving lever connects the gearshift spanner by shift lever axis; By the bearing installation differential assembly, with fast universal-joint; Differential assembly comprises that differential carrier, planetary wheel, axle side gear connect and compose; Main deceleration driven gear is installed on the differential assembly; Mileage output driven gear is installed in the axis hole of rear side housing by wheel shaft, and exports the driving gear engaged transmission with mileage.
The invention has the advantages that drive motor and two gear change-speed boxs link into an integrated entity, and have formed a modular dynamic assembly, this modular dynamic assembly is easy to assembling and maintenance.The change-speed box of this dynamic assembly is the speed-changing mechanism of two work gears, i.e. low gear, high gear.Vehicle uses the low gear operation when heavy duty is climbed, when the mild road traveling of underloading, adopt the high speed gear operation.Speed-changing mechanism adopts synchro to realize on second, engages with low speed or high speed driven gear respectively by synchro and realizes low speed and high-speed cruising.Compact conformation, flexible operation, convenience.Can reduce the rating horsepower that uses motor.
