Abstract
The utility model discloses a heavy double-drive differential motor for an electromobile. The heavy double-drive differential motor comprises a motor stator and rotor. The motor stator and rotor is fixed on a motor shaft. A primary driving gear is sleeved on the motor shaft. The primary driving gear is embedded with a primary driven gear which is fixed on a secondary driving gear. The secondary driving gear is embedded with a secondary driven gear. The secondary driven gear is fixed on a differential bag. Four straight bevel gears and bevel gear small shafts are arranged inside the differential bag, wherein, two straight bevel gears are connected with two half shafts. As the heavy double-drive differential motor adopts double shafts for simultaneous drive, the driving efficiency is high; and the moment is large; the moving electromobile not only turns flexibly but also has low probability of turning on the side easily. All of the components of the transmission mechanism of the heavy double-drive differential motor are made of steel and are lubricated with engine oil. The utility model has the advantages of long service life, convenient installation and adjustment, capability of turning clockwise and anti-clockwise and the like.
Description
Technical field
The utility model relates to a kind of motor, is specifically related to the heavy two differential speed motors that drive of a kind of electric motor car.
Background technology
The motor that uses in existing electro-tricycle or the electric four-wheel vehicle all belongs to the single shaft kind of drive, be that motor output shaft directly drives a wheel driving, there is not speed difference because two-wheeled rotates when turning, the radius of turn of car is big when adding the driving turning, be two rear tread from one times, turn on one's side easily in the time of will causing driving to turn like this, and shortcomings such as the wearing and tearing of two tires are inconsistent, driving parts quick abrasion, transmission efficiency is low, moment is little.
Summary of the invention
The utility model is in order to solve the deficiencies in the prior art, provide a kind of electric motor car when driving is turned not only flexibly but also be difficult for rollover, big, the two differential speed motors that drive of the nonabradable heavy type of drive disk assembly of moment.
The technical scheme that its technical problem that solves the utility model adopts is: the heavy two differential speed motors that drive of a kind of electric motor car, comprise electric machine rotor, described electric machine rotor is fixed on the motor shaft, suit first order driving gear on the described motor shaft, described first order driving gear and the embedding mutually of first order driven gear, described first order driven gear is fixed on the driving gear of the second level, described second level driving gear and the embedding mutually of second level driven gear, described second level driven gear is fixed on differential and wraps, be provided with the little axle of awl tooth in the middle of the described differential bag, the front and back of described differential bag inside are provided with two little straight bevel gears, the little axle of awl tooth inserts in the aperture of two little straight bevel gears, described differential bag is provided with two big straight bevel gears about inside, two big straight bevel gear one ends mesh with two little straight bevel gears respectively, and the other end is connected with two semiaxis respectively.
Compared with prior art, the utility model is that twin shaft drives the efficient height simultaneously, moment is big, not only flexible but also difficult rollover when driving a vehicle turning, the transmission mechanism parts are steel component and adopt oil lubricating, but advantages such as long service life, installation rotating easy to adjust.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 electric machine rotor, 2 motor shafts, 3 first order driving gears, 4 first order driven gears, 5 second level driving gears, 6 second level driven gears, 7 little straight bevel gears, 8 big straight bevel gears, 9 differential bags, 10 semiaxis, the little axle of 11 awl teeth.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, electric machine rotor 1 is fixed on the motor shaft 2, first order driving gear 3 is sleeved on the motor shaft 2, first order driving gear 3 and first order driven gear 4 embedding mutually, first order driven gear 4 is fixed on the second level driving gear 5 by flat key, second level driving gear 5 and second level driven gear 6 embedding mutually, second level driven gear 6 is fixed on the differential bag 9 by screw, be provided with 4 straight bevel gears in the differential bag 9, differential bag 9 profiles are column type branch left and right sides two halves, two little straight bevel gears 7 are fore-and-aft direction in differential bag 9, the little axle 11 of awl tooth inserts in the aperture of two little straight bevel gears 7, two big straight bevel gears 8 are located at respectively in the left and right sides two halves of differential bag 9, two little straight bevel gears 7 respectively with about two big straight bevel gears 8 engagements, by bolt two halves differential bag 9 is coupled together, differential bag 9 and 4 straight bevel gears have constituted differential mechanism, the spline of two-semiaxle 10 1 ends inserts respectively in the splined hole of two big straight bevel gears 8, is connected with two big straight bevel gears 8.
When the electric motor car rectilinear motion, power supply drives electric machine rotor 1 running, electric machine rotor 1 drives motor shaft 2 motions, motor shaft 2 left ends drive first order driving gear 3 and rotate, gear driven first order driven gear 4 on the first order driving gear 3 rotates, 4 rotations of first order driven gear drive second level driving gear 5 and rotate, second level driving gear 5 rotates, drive second level driven gear 6, and second level driven gear 6 is fixed on the differential bag 9, driving whole differential bag 9 rotates, drive 10 runnings of two semiaxis, an end of two semiaxis 10 connects two wheels of electric motor car by flat key or spline, thereby turns a wheel, 4 straight bevel gears in the differential bag 9 do not rotate and only play transfer torque at this moment, and two semiaxis 10 can drive the purpose that has reached two drivings simultaneously.
When the electric motor car turning motion, 4 straight bevel gears in the differential bag 9 begin mutual motion, the gear ratio of the straight bevel gear in the speed of two wheels and the differential bag is directly proportional, promptly Nei Ce wheel speed is slower than the speed of outside wheel, the uniform purpose that so just reaches that turning flexibly, can not turned on one's side and two tires wear and tear; By the size of change stator, rotor and the number of turns and the bundle number of stator coil, the power of motor can reach 350W-1000W.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection range of the present utility model.
