Technical field
The utility model relates to the electric four-wheel vehicle actuating device, specifically relates to have the driving device for electric vehicle of high to low gear speed change.
Background technology
Battery-driven car is driven by DC machine or alternating current dynamo, is easy to realize stepless change, and present most of battery-driven cars are not with change-speed box, and is only with a fixing retarder, therefore simple in structure, easy to operate.Since elec. vehicle starting and when climbing moment of torsion big, big several times and even tens times of the electric current of current of electric during than normal operation has influence on the service life of motor and storage battery, and shortened the boat mileage that continues, when serious even burn out motor.Motor just can reach permanent power output when high speed, the big speed of moment of torsion is low during climbing, and the motor horsepower output reduces on the contrary, so hill climbing ability is poor.In order to overcome above-mentioned shortcoming, adopt the Automotive transmission repacking at present, before actuating device, install an independent change-speed box additional, adopt low gear when starting and climbing, reduced rush current, increased drive torque, improved grade climbing performance.Owing to increased independent change-speed box, the actuating device cost improves one times nearly; Because the Automotive transmission multi-gear transmission, not only complicated operation has also influenced the performance of motor stepless change performance.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and a kind of intensity height, size is little, cost is low, the easy to operate driving device for electric vehicle with high and low retaining speed change are provided.
The utility model is made up of drive axle casing and end cap, the high gear input gear is installed in the drive axle casing, the input gear axle, the high gear driven gear, the low gear driven gear, the output driving gear shaft, the output driven gear, the spline on the input gear axle connects with motor, miniature gears on the input gear axle is meshed with the low gear driven gear, the high gear input gear is fixed on the input gear axle by key, and meshes with the high gear driven gear, and it is characterized in that: erection of transmission is in the drive axle casing, the variable part is by input gear axle and output driving gear shaft and high gear driven gear, the input gear axle, the low gear driven gear is formed, and directly reaches output gear then; On the spline of described output driving gear shaft supporting gear is housed, the spline tooth cover is housed on the male splines of supporting gear, high gear driven gear and low gear driven gear also can slide on the output driving gear shaft in the supporting gear both sides by bearing installation.
For further realizing above-mentioned purpose, described output driven gear is fixed on the diff.
Inner spline gear that described spline tooth puts and high gear driven gear, the joint male splines of low gear driven gear is a raker tooth.Spline tooth puts the shift fork that is connected with the band declutch shift shaft, and control setup (electrical controller or hand-control device) is connected with shift fork.
Adopt actuating device of the present utility model, the intensity height, size is little, cost is low, easy to operate.Owing to adopt two retaining speed changes, use the low speed gear when starting and climbing, big retarding than the time motor load reduce, grade climbing performance improves; Because rush current reduces, and has protected motor and storage battery, has saved electric energy effectively, has improved the continuation of the journey mileage.When normal road driving, be in a high speed gear with vehicle and motor coupling always, give full play to the stepless change performance of electrical motor, operate simple and convenient.The merging of high to low gear speed change is installed in the actuating device, becomes one, and effectively reduces cost.The utility model can electronic or manual shift, and is economical and practical.But arranged parallel or T type are settled.Not only be used on the electronlmobil, also can be used on electro-tricycle, Caddy etc.
