The motor that existing drive system of electric motor vehicle is used, is generally common DC motor, thereby after power transmission shaft is connected with the main shaft of motor, also want connection reducer and differential mechanism, because decelerator and differential mechanism are all arranged on the outside of motor, so not only noise is large, and the transfer ratio of energy is low.
In addition, the motor that also has a kind of version, the differential mechanism of this kind of motor is placed on a side of motor, the shortcoming of this vehicle bridge is because motor and differential mechanism are distinct structures, the requirement of the short and thick ability meeting spatial that therefore size of motor need to be done, and short and thick structure also can reduce to some extent to motor output torque.
Summary of the invention
The problem to be solved in the present invention is: provide a kind of simple in structure, differential mechanism and motor are integrated to formula structure thereby noise is little and energy conversion rate is high motor direct driving vehicle bridge magneto.
In order to address the above problem, motor direct driving vehicle bridge magneto of the present invention, comprise motor casing, be separately fixed at motor left end cap and the motor right end cap at two ends, motor casing left and right, in described motor casing, be provided with motor stator winding, in described motor stator winding, be provided with rotor winding, in described rotor winding, be fixed with differential mechanism left shell and right differential housing, in described differential mechanism left shell and right differential housing, be provided with differential mechanism, the two ends, left and right of described differential mechanism are respectively provided with an axle half shafts connecting interface, in described rotor winding, be fixed with rotor left half axle and the rotor right axle shaft of hollow, described rotor left half axle is fixedly connected with differential mechanism left shell, described rotor right axle shaft is fixedly connected with right differential housing.
In order to make rotor left half axle and rotor right axle shaft rotate more stably, to better export energy, motor direct driving vehicle bridge magneto of the present invention, in described motor left end cap, be provided with one for the left support bearing of support rotor left half axle, in described motor right end cap, be provided with one for the right support bearing of support rotor right axle shaft.
For can be firm by differential mechanism left shell and firm being fixed together of right differential housing, motor direct driving vehicle bridge magneto of the present invention, is provided with set bolt between described differential mechanism left shell and right differential housing.
The beneficial effect that the present invention obtains is: (1) is simple in structure, (2) by differential mechanism integrated with rotor winding in, wherein differential mechanism left shell is all fixedly connected with rotor winding with right differential housing, the two ends, left and right of differential mechanism are respectively provided with an axle half shafts connecting interface, on differential mechanism left shell and right differential housing, be fixedly connected with respectively a roots rotor left half axle and rotor right axle shaft, in the time of concrete driving electric motor car operation, vehicle bridge left half axle and vehicle bridge right axle shaft are docked with two axle half shafts connecting interfaces respectively, so, by rotor left half axle, rotor right axle shaft, the cooperation of vehicle bridge left half axle and vehicle bridge right axle shaft is rotated, can be by power transmission to wheel, when wheel turns round, effect due to differential mechanism, also adjustment vehicle bridge left half axle that can be promptly and accurately and the rotating speed of vehicle bridge right axle shaft, to adapt to turning round of wheel, therefore, after differential mechanism is integrated in rotor winding, improved the sealing property of differential mechanism, so can greatly reduce the noise that differential mechanism produces, simultaneously, after differential mechanism is integrated in rotor winding, make rotor left half axle, rotor right axle shaft, the length of vehicle bridge left half axle and vehicle bridge right axle shaft has had the space increasing, so can improve the moment of torsion of motor, (3) in motor left end cap, be provided with one for the left support bearing of support rotor left half axle, in motor right end cap, be provided with one for the right support bearing of support rotor right axle shaft, thereby can make rotor left half axle and rotor right axle shaft rotate more stably, outputting power more stably.
