Abstract:
The present invention discloses a dual-motor coupling drive axle with a torque vectoring function. The dual-motor coupling drive axle includes: a main drive mechanism; a bevel gear differential; a TV control drive mechanism; a first single-row planetary gear train, of which a first sun gear is rotatably supported on a first half shaft and a first gear ring is connected with an output end of the TV control drive mechanism; a second single-row planetary gear train, of which a second gear ring is fixed to a drive axle housing and a second sun gear is coaxially and fixedly connected with the first sun gear; a third single-row planetary gear train.

Claim (Index 8):
A dual-motor coupling drive axle with a torque vectoring function, comprising:\n a main drive mechanism arranged on one side of a differential, wherein an output end of the main drive mechanism is connected with a differential housing, so that rotary power may be transferred to the differential housing; a TV control drive mechanism arranged on the other side of the differential; a first single-row planetary gear train including a first sun gear, a first planetary gear, a first planet carrier and a first gear ring, wherein the first sun gear is rotatably supported on a first half shaft, and the first gear ring is connected with an output end of the TV control drive mechanism; a second single-row planetary gear train including a second sun gear, a second planetary gear, a second planet carrier and a second gear ring, wherein the second gear ring is fixed to a drive axle housing, and the second sun gear is coaxially and fixedly connected with the first sun gear; a third two-stage single-row planetary gear train including a third sun gear, a third two-stage planetary gear, a third planet carrier and a third gear ring, wherein the third sun gear is fixedly connected with the differential housing, and the third gear ring is fixedly connected with the second planet carrier; a first clutch respectively connected with the first half shaft and the first planet carrier for separating or engaging the first half shaft and the first planet carrier; a second clutch respectively connected with the first planet carrier and the drive axle housing for separating or engaging the first planet carrier and the drive axle housing; a third clutch respectively connected with the first half shaft and the third planet carrier for separating or engaging the first half shaft and the third planet carrier; and a fourth clutch respectively connected with the third planet carrier and the drive axle housing for separating or engaging the third planet carrier and the drive axle housing, wherein the first single-row planetary gear train and the second single-row planetary gear train have the same characteristic parameter.
