Compared with the prior art adopting the differential mechanism input gear and the speed reduction driven gear with the vertical axial lines, the gear shifting differential speed motor adopting the mode has the advantages that a straight gear or a bevel gear can be adopted for replacing a cone gear for transmission, and the torque transmission is favorably realized, so the dimension of parts is reduced, the rotating inertia is reduced, and the processing cost is also favorably reduced.

Description

The variable block differential speed motor
Technical field
The utility model relates to a kind of integrated drive unit, particularly a kind of incorporate variable block differential speed motor that is used for electric motor car.
Background technology
Light-weight electric vehicle motor commonly used does not have mechanical variable block, cause relatively difficulty of electric motor car climbing, damage motor and storage battery easily, and existing light-weight electric vehicle is for example in the electro-tricycle, usually do not adopt differential mechanism, cause the wearing and tearing of tire and part bigger.And in motor vehicle, adopting the transmission parts of fuel vehicle to exist power transmission loss too big, big problem perhaps takes up room.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of variable block differential speed motor, is applicable to the transmission of light-weight electric vehicle, and it is little to take up room, and power transmission loss is few.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of variable block differential speed motor, motor is connected with the variable block gear train, the output shaft of variable block gear train is connected with differential mechanism by train of reduction gears, described variable block gear train, train of reduction gears and differential mechanism are installed in the housing, and motor at least a portion is installed in the housing.
At least be provided with at least one group of shifting slide gear in the described variable block gear train.
Be provided with two groups of shifting slide gears in the described variable block gear train.
Described shifting slide gear and shift fork flexibly connect.
Differential mechanism input gear in the described differential mechanism and the deceleration driven gear in the train of reduction gears adopt spur gear or angular gear.
The differential mechanism input gear in the described differential mechanism and the parallel axes of the deceleration driven gear in the train of reduction gears.
A kind of variable block differential speed motor that the utility model provides, by adopting above-mentioned structure, and cancelled clutch, thereby reduced power transmission loss, and reduced and taken up room, type of drive from motor and oil-burning machine, because motor is compared to oil-burning machine, by adopting methods such as frequency conversion, matrix control, its start and stop, speed change are more easy, therefore can cancel traditional clutch, and when descending, can change motor into generator by circuit, recuperated energy, and the resistance of slowing-down brake is provided.
Can use comparatively cheap motor thereby the utility model has still kept the variable block gear train, and meet existing user's the custom of controlling.Because adopt motor-driven, it is little to take up room, therefore variable block gear train, train of reduction gears and differential mechanism can be installed in the same housing, motor is installed in the housing to major general's running part, and overall structure is more compact.Also avoided the influence of dust and adverse circumstances, prolonged the useful life of whole drive unit driving parts.Different with the driving of oil-burning machine, little because take up room, the differential mechanism input gear in the scheme of optimizing in the differential mechanism and the parallel axes of the deceleration driven gear in the train of reduction gears, compare with their axis normal in the prior art, this mode helps the transmission of moment of torsion, thereby reduces the size of part by substituting Bevel Gear Transmission with spur gear or helical gear, and the reduction moment of inertia, also help cutting down finished cost.
Description of drawings
