Problems solved by technology

[0002] The existing pure electric special vehicles using the main and auxiliary double motor drive system, when in the working state, the main drive motor drives the main drive shaft traveling device, and the auxiliary motor drives the special vehicle operating device; when the special vehicle is in the non-working state, the main drive motor drives The main drive shaft travel device and the auxiliary motor do not work; when the special vehicle is in the working state, the walking speed is low, and the power required by the main drive motor is small. If it is matched with a high-power main drive motor, it will easily lead to waste of motor power; in the non-working state Under such circumstances, when the special vehicle is in the working conditions of rapid start, rapid acceleration, climbing steep slopes, high-speed driving, etc., the main drive motor needs a large power. If it is matched with a small power main drive motor, it will easily lead to insufficient power of the special vehicle; and the special vehicle In the non-working state, the working motor does not work, which also causes idle waste of the working motor to a certain extent

Embodiment 1

[0023] In this embodiment, a special vehicle power system based on a single-ended dual-output operation / travel drive motor includes a vehicle controller 8, a main drive motor and its controller 2, an operation / travel drive motor and its controller 4, and a dual-unidirectional clutch transmission 6;

[0024] The double one-way clutch transmission device 6 includes a driving shaft 6 (f), a driving shaft driving gear 6 (e), a first driven shaft 6 (i), a first driven shaft driven gear 6 (g), First one-way clutch 6(h), second driven shaft 6(c), second driven shaft driven gear 6(a), second one-way clutch 6(b), second driven shaft clutch 6 (d).

[0025] The inner ring of the first one-way clutch 6 (h) is fixedly mounted on the first driven shaft 6 (i), and the outer ring is fixedly mounted on the driven gear 6 (g) of the first driven shaft; the second one-way clutch The inner ring of the clutch 6 (b) is fixedly mounted on the second driven shaft 6 (c), and the outer ring is fixedly...

Embodiment 2

[0028] This embodiment discloses a control strategy for the power system of a special vehicle based on a single-ended double-output operation / travel drive motor. The vehicle controller 8 in the power system controls the coordinated work of the entire power system, which can be judged and determined according to the working conditions of the vehicle. Select the appropriate driving mode control strategy. The driving mode of the special vehicle includes the main driving motor 2 (a) single motor driving mode, the normal operation mode, the main driving motor 2 (a) and the working / traveling driving motor 4 (b) timely four-wheel drive mode, the power system drive mode control strategy steps are as follows:

[0029](1) The power system first judges the mode signal of the special vehicle working condition. The vehicle controller 8 judges whether it is the starting working condition according to the key position signal, the transmission gear signal and the vehicle speed signal. If it is...
