Description
Technical field
The utility model relates to low-speed electronic automobile technical field, refers to a kind of low-speed electronic automobile variable speed box assembly especially.
Background technique
Low-speed electronic automobile refers to the simple and easy four-wheel pure electric automobile of speed lower than 70km/h.General maximum speed is 70km/h, and profile, properity and fuel-engined vehicle are similar.Low-speed electronic automobile gearbox, vital part is gear, higher for quietness and self horsepower requirements.Various low-speed electronic automobile gearboxes in the market, unreasonable structure, Gear Processing precision is low, for GB 6-7 level, when causing gearbox to work, gears meshing is not steady, easily produces noise, and self energy consumption is large, thus have impact on the quietness of car load, reduce the course continuation mileage of vehicle.
Model utility content
The utility model proposes a kind of low-speed electronic automobile variable speed box assembly, gearbox casing inner structure is more reasonable, achieves the steady engagement of gear during gearbox work, thus reduces noise and energy consumption, improve quietness and the flying power of vehicle.
The technical solution of the utility model is achieved in that low-speed electronic automobile variable speed box assembly, comprise gear box casing, input shaft is rotatablely equipped with in described gear box casing, jack shaft and output shaft, described input shaft, jack shaft and output shaft arranged in parallel, described input shaft and motor pass through spline joint, described output shaft is connected by differential mechanism with vehicle semiaxle, described input shaft is provided with input gear, described jack shaft is provided with intermediate input gear and middle output gear, described output shaft is provided with output gear, described input gear is meshed with intermediate input gear, described middle output gear is meshed with output gear.
Preferably, described gear box casing comprises left half casing and right half casing.
Preferably, the Gear Processing precision of described input gear and intermediate input gear is GB 4-5 level.
Preferably, the Gear Processing precision that described middle output gear and output gear are meshed is GB 4-5 level.
Have employed technique scheme, the beneficial effects of the utility model are: because the input shaft of low-speed electronic automobile variable speed box assembly and motor pass through spline joint, output shaft and vehicle semiaxle are connected by differential mechanism to be stated input shaft and is provided with input gear, jack shaft is provided with intermediate input gear and middle output gear, output shaft is provided with output gear, input gear is meshed with intermediate input gear, and middle output gear is meshed with output gear.Motor operation drives input gear to rotate, and input gear and then drive intermediate input pinion rotation, middle output gear drives output gear to rotate, the rotation of the rotating band motor vehicle semiaxis of final output gear, thus makes wheels travel.The engagement running of gear is the mode realizing vehicle traveling, and the stationarity of gears meshing and running just determines quietness and the energy consumption of gearbox.The present invention reaches GB 4-5 level by making gearbox casing inner structure grade of accuracy that is more reasonable and improvement Gear Production technique raising gear, thus ensure that the stationarity that gear operation engages, thus making gearbox operation process mute, gearbox self energy consumption significantly reduces.
