The transmission provided by the embodiment of the present application is described in detail by specific embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 1, the embodiment of the present application discloses a transmission device, which may be a transfer case, a gearbox, or the like. The transmission device of the embodiment includes an input shaft 100, a transmission gear 110 is sleeved on the input shaft 100, the transmission gear 110 is used for meshing with an output gear on other shafting to drive the input shaft 100 to rotate, a first end of the input shaft 100 is detachably connected with a first output shaft 300 through a first clutch mechanism 200, a second end of the input shaft 100 is detachably connected with a second output shaft 500 through a second clutch mechanism 400, and the input shaft 100, the first output shaft 300 and the second output shaft 500 are all rotatably arranged on a box 800 of the transmission device.

In the embodiment of the present application, the first end of the input shaft 100 is detachably connected with the first output shaft 300, the second end of the input shaft 100 is detachably connected with the second output shaft 500, when both the first output shaft 300 and the second output shaft 500 need to output power, the input shaft 100 is connected with the first output shaft 300 through the first clutch mechanism 200, and the input shaft 100 is connected with the second output shaft 500 through the second clutch mechanism 400, so that the first output shaft 300 and the second output shaft 500 can output power at the same time; when only the first output shaft 300 is required to output power, the input shaft 100 is connected with the first output shaft 300 through the first clutch mechanism 200, and the input shaft 100 is disconnected with the second output shaft 500 through the second clutch mechanism 400, so that the first output shaft 300 can output power and the second output shaft 500 does not output power; when only the second output shaft 500 is needed to output power, the second clutch mechanism 400 connects the input shaft 100 with the second output shaft 500, and the first clutch mechanism 200 disconnects the input shaft 100 from the first output shaft 300, so that the second output shaft 500 can output power and the first output shaft 300 does not output power. Therefore, according to the power take-off device, three power take-off modes, namely, the power take-off mode that the first output shaft 300 and the second output shaft 500 output power simultaneously and the power take-off mode that the first output shaft 300 outputs power independently and the power take-off mode that the second output shaft 500 outputs power independently can be realized by adjusting the states of the first clutch mechanism 200 and the second clutch mechanism 400, so that the power take-off mode can be adjusted according to different transmission requirements, and the problem that when two output ends share one output shaft, two output ends must output power simultaneously, and power is wasted is solved.

Optionally, the axis of the input shaft 100 and the axis of the first output shaft 300 may not be collinear, taking the input shaft 100 as an example, a transmission shaft is detachably connected to the first end of the input shaft 100 through the first clutch mechanism 200, and is in transmission connection with the first output shaft 300, wherein the input shaft 100 and the transmission shaft are coaxially arranged, and the axis of the first output shaft 300 and the axis of the transmission shaft are not collinear, at this time, the present application may implement that the input shaft 100 and the first output shaft 300 are in detachable connection.
