The first housing 310 and the second housing 320 are integrally cast, so that the first driving device 11 and the second driving device 12 are conveniently integrated, and the occupied area of the first driving device 11 and the second driving device 12 is reduced.

Therefore, the drive assembly 1 of the vehicle according to the embodiment of the utility model has the advantages that the single motor can independently drive the wheel, the structure is compact, and the like.

A drive assembly 1 of a vehicle according to an embodiment of the present invention is described below with reference to the accompanying drawings.

In some specific embodiments of the present invention, as shown in fig. 1 to 3, a drive assembly 1 of a vehicle according to an embodiment of the present invention includes first and second drive devices 11 and 12, first and second wheels 21 and 22, and first and second speed change devices 100 and 200.

In some embodiments of the present invention, the axis of the first drive means 11 and the axis of the second drive means 12 are parallel and extend in a second direction, the first direction being perpendicular to the second direction. The arrangement is convenient for the reasonable arrangement of the first driving device 11 and the second driving device 12, the first wheel 21 and the second wheel 22 in the driving assembly 1, and the occupied space of the driving assembly 1 is reduced.

Specifically, the first direction may be a front-rear direction (the front-rear direction is shown in fig. 3), the second direction may be a left-right direction (the left-right direction is shown in fig. 3, it should be understood that the above-mentioned direction is defined only for convenience of description of the drawings and does not limit the actual installation position and direction of the drive assembly 1), the first drive device 11 and the second drive device 12 are disposed at intervals in the front-rear direction, the axes of the output shafts of the first drive device 11 and the second drive device 12 extend in the left-right direction, the first wheel 21 and the second wheel 22 are disposed in the left-right direction, and the axes of the first wheel 21 and the second wheel 22 are located on a straight line and extend in the left-right direction. The first driving device 11 drives the first wheel 21 to rotate, and the second driving device 12 drives the second wheel 22 to rotate, so that the first driving device 11, the second driving device 12, and the first wheel 21 and the second wheel 22 are arranged compactly and reasonably.

The first driving device 11 drives the first gear 110 to rotate, the first gear 110 can drive the second gear 120 to rotate, because the number of teeth of the second gear 120 is greater than that of the first gear 110, the rotating speed of the first gear 110 transmitted to the second gear 120 is reduced, the second gear 120 and the third gear 130 are coaxial gears, the rotating speeds of the second gear 120 and the third gear 130 are the same, the third gear 130 drives the fourth gear 140 to transmit, because the number of teeth of the fourth gear 140 is greater than that of the third gear 130, the rotating speed of the third gear 130 transmitted to the fourth gear 140 is further reduced, so that the output rotating speed of the first driving device 11 is reduced to the rotating speed required by the first wheel 21.

This arrangement facilitates the first drive means 11 driving the first wheel 21 independently and the second drive means 12 driving the second wheel 22 independently. Meanwhile, reasonable output rotating speeds can be respectively provided.

Specifically, the first driving device 11 can drive the first wheel 21 to rotate through the first transmission device 100, the second driving device 12 can drive the second wheel 22 to rotate through the second transmission device 200, so that the first driving device 11 independently drives the first wheel 21 to rotate, and the second driving device 12 independently drives the second wheel 22 to rotate.

In some alternative embodiments of the present invention, the axis of the output of the first transmission 100 is collinear with the axis of the output of the second transmission 200. The arrangement is such that the drive connection with the first wheel 21 and the second wheel 22 is made such that the rotation axes of the first wheel 21 and the second wheel 22 are in the same line, which facilitates the movement of the vehicle.

For example, the first transmission case 410 and the second transmission case 420 are disposed at an interval in the left-right direction, the first transmission case 410 is disposed at the left end of the first case 310, so that the first transmission 100 is disposed in the first transmission case 410 without affecting the rotation of the first wheel 21 driven by the first transmission 100, and the first transmission case 410 can seal the left side surfaces of the first case 310 and the second case 320, so as to ensure the relative tightness of the first case 310 and the second case 320. The second transmission case 420 is disposed at the right end of the first case 310, so that the second transmission 200 is disposed in the second transmission case 420 without affecting the rotation of the second wheel 22 driven by the second transmission 200, and the second transmission case 420 can seal the right side surfaces of the first case 310 and the second case 320, so as to ensure the relative tightness of the first case 310 and the second case 320.
