in the normal use process of the driving output shaft 6, the main rotating force of the driving output shaft 6 is input into the power transmitted to the gearbox by the engine, when the speed of the automobile is lower than a certain set value, the driving motors 4 on two sides of the top of the supporting plate 5 intervene in the power transmission of the driving output shaft 6, when the speed of the automobile is higher than the certain set value, whether the driving motors 4 intervene in the transmission of the driving output shaft 6 or not can be considered, when the speed of the automobile is lower than the set value, the set driving motors 4 rotate the output shaft 2 welded through the output end and further rotate the second belt roller 17, the second belt roller 17 and the first belt roller 16 on the outer ring of the driving output shaft 6 are in transmission connection through a triangular belt, after the output end of the driving motors 4 starts to rotate, the rotating directions of the two driving motors 4 are opposite, and then simultaneously rotated, the driving output shaft 6 will obtain the same rotating force by the acting force of the second belt roller 17, and then the rotating speed is increased;
under the action of the same-direction rotation of the driving output shaft 6, two ends of the driving output shaft 6 rotate in the same direction to form a second bevel gear 11 and a third bevel gear 18 which are respectively positioned in the front transmission shaft box 1 and the rear transmission shaft box 3, the welding positions of a first bevel gear 10 and a fourth bevel gear 19 which are respectively welded on the outer rings of two driven shafts 9 are opposite, when the driving output shaft 6 starts to drive the fourth bevel gear 19 and the first bevel gear 10, the two driven shafts 9 in the front transmission bearing box 1 and the rear transmission shaft box 3 start to rotate in the same direction due to the meshing direction relationship between the fourth bevel gear 19 and the first bevel gear 10, so that the half shafts 7 on two sides of the front transmission bearing box 1 and the rear transmission shaft box 3 are driven to rotate, the same rotation direction of the half shafts 7 is backward, the integral driving direction of the automobile is a forward state, and an engine does not intervene in the transmission work of the driving output shaft 6 at low speed, after the output end of the driving motor 4 rotates reversely, the rotation direction of the driving output shaft 6 is opposite to the forward state, and the overall driving direction of the automobile is in a backward state;
meanwhile, when the driven shaft 9 firstly transmits the rotating force to the coupler 12 while the driving output shaft 6 drives the driven shaft 9 and before the driven shaft 9 transmits the driving force to the half shaft 7, the side of the coupler 12 far away from the driven shaft 9 elastically offsets the rotating stress through the spring between the telescopic pipe 14 and the shaft sleeve 15.
