A power drive apparatus 100 according to an embodiment of the present invention is described below with reference to fig. 1.

According to the utility model discloses power drive device 100 can include: clutch 1, gearbox, jackshaft 3 and motor 7.

As shown in fig. 1, the clutch 1 has a clutch driving disk 12 and a clutch driven disk 11, the gearbox has a gearbox input shaft 2, an intermediate shaft 3 is connected between the clutch driven disk 11 and the gearbox input shaft 2, the electric machine 7 has a connecting shaft 4, and the connecting shaft 4 is connected between the intermediate shaft 3 and the gearbox input shaft 2.

Specifically, the clutch driving plate 12 is connected to the driving device input shaft 6 of the power driving device 100 by a welding process, but is not limited thereto, so that the engine can transmit power to the clutch 1, and the clutch driven plate 11 is connected to the intermediate shaft 3 by welding, but is not limited thereto, so that the clutch 1 can transmit power to the intermediate shaft 3, and the intermediate shaft 3 transmits power from the intermediate shaft 3 to the transmission input shaft 2 by being connected to the connecting shaft 4 and the transmission input shaft 2, respectively, and so that the motor 7 can transmit power to the transmission input shaft 2 and the intermediate shaft 3, wherein the function of the power driving device 100 to interrupt power can be realized by closing and opening the clutch 1.

Because the traditional power driving device does not have an intermediate shaft, the input shaft of the gearbox is directly connected with the clutch driven disc, and a needle bearing needs to be arranged between the input shaft of the gearbox and the connecting shaft and is used for supporting, rotating and transmitting, so that the cost is high.

And the embodiment of the utility model provides a through increase jackshaft 3 in power drive device 100, make jackshaft 3 carry out fixed connection with clutch driven plate 11, connecting axle 4 and gearbox input shaft 2 as the medium of transmission power to realize the transmission of power, can avoid from this installing bearing between gearbox input shaft 2 and connecting axle 4, can effectively reduce power drive device 100's manufacturing cost.

According to the utility model discloses power drive device 100, this power drive device 100 is through increasing jackshaft 3 to realize clutch driven plate 11 and connecting axle 4 and gearbox input shaft 2's lug connection, can avoid installing bearing additional between connecting axle 4 and gearbox input shaft 2, and then can effectively reduce power drive device 100's manufacturing cost.

As shown in fig. 1, the connecting shaft 4 is in spline fit connection with the intermediate shaft 3, and the connecting shaft 4 is in spline fit connection with the transmission input shaft 2. This enables the intermediate shaft 3, the connecting shaft 4, and the transmission input shaft 2 to be stably connected together for stable power transmission.

Because traditional clutch driven plate directly carries out splined connection with the gearbox input shaft, when the rotor of motor drove the high-speed rotation of connecting axle in power drive arrangement, because dynamic balance problem can produce radial force between connecting axle and gearbox input shaft, and this radial force can exert an influence to the axial connection between gearbox input shaft and the clutch driven plate, but if the rotor of motor carries out rigid connection with the clutch, then can lead to the clutch to receive radial force when the separation combines, lead to the frictional force change that the friction disc received to influence power transmission's control.

However, the embodiment of the utility model provides a through using intermediate shaft 3 and clutch driven plate 11 to carry out welded fastening, carrying out splined connection through intermediate shaft 3 and connecting axle 4, rather than welded fastening connects, from this, can effectual reduction because of the influence of the radial force that the balanced problem of the rotor of motor 7 produced to power drive 100 power transmission.

Further, one side of the connecting shaft 4 is provided with an internal spline 41, one end of the intermediate shaft 3 is provided with a first external spline 31, the first external spline 31 is in fit connection with the internal spline 41, the other side of the connecting shaft 4 is provided with another internal spline 41, one end of the gearbox input shaft 2 is provided with a second external spline 21, and the second external spline 21 is in fit connection with the other internal spline 41 so as to realize stable transmission of power. The input shaft 2 of the gearbox is sleeved in the intermediate shaft 3, so that the axial arrangement distance between the input shaft and the intermediate shaft can be effectively shortened, and the axial width of the power driving device 100 is further reduced.

As shown in fig. 1, a seal ring 5 is provided between the intermediate shaft 3 and the connecting shaft 4. Because the intermediate shaft 3 is directly connected with the connecting shaft 4 through the spline, and the input shaft 2 of the gearbox is also directly connected with the connecting shaft 4 through the spline, a needle bearing does not need to be installed, therefore, only the O-shaped sealing ring 5 needs to be directly used for sealing between the intermediate shaft 3 and the connecting shaft 4, a larger oil seal does not need to be used for sealing, and the integral manufacturing cost of the power driving device 100 can be effectively reduced.

Further, a seal ring 5 is interposed between an outer wall surface of the intermediate shaft 3 and an inner wall surface of the connecting shaft 4. Therefore, the space of one side, close to the clutch 1, of the connecting shaft 4 and the space of one side, close to the gearbox, of the connecting shaft 4 can be completely isolated, and the influence on the normal operation of the flywheel due to the fact that oil enters the space of one side, close to the gearbox, of the connecting shaft 4 where the flywheel is located is prevented.

Specifically, the outer wall surface of the intermediate shaft 3 has a first limiting groove 32 recessed in the intermediate shaft 3, the inner wall surface of the connecting shaft 4 has a second limiting groove 42 recessed in the connecting shaft 4, and the seal ring 5 is clamped between the first limiting groove 32 and the second limiting groove 42. From this, through the spacing installation of first spacing groove 32 and second spacing groove 42 to install the stable spacing of sealing washer 5 on fixed position, and then can effectively avoid sealing washer 5 to slide between jackshaft 3 and connecting axle 4, guaranteed the installation stability of sealing washer 5, and then guaranteed the sealed effect of sealing washer 5.

As a preferred embodiment, the connecting shaft 4 is arranged coaxially with the intermediate shaft 3 and the gearbox input shaft 2. Therefore, the power transmission mode is simple, and arrangement and connection among all parts are facilitated.
