Abstract

The invention discloses a special vehicle power system based on a dual-end output work/traveling driving motor. The special vehicle power system comprises a vehicle control unit, a main driving motor and its controller, a driving/traveling driving motor and its controller, a first clutch transmission device, and a second clutch transmission device; the vehicle control unit controls the coordinating work of the whole power system, and the main driving motor is connected to a main driving shaft walking device; during the work, the driving/traveling driving motor is used as a working driving device; when the vehicle accelerates and climbs, the driving/traveling driving motor can also be used as an assistant driving device; first and second clutch input disks in the first and second clutch transmission devices are respectively installed at both ends of the output shaft of a work/traveling driving motor rotor, a first driven shaft is connected to a working device and a second driven shaft is connected to an assistant driving shaft traveling device; the system can realize the functional conversion of the assistant driving traveling and work of the work/traveling driving motor; on the basis of ensuring the dynamic property of the whole vehicle, the system can reduce the power of the main driving motor and optimize the vehicle energy utilization rate.

Description

technical field [0001] The invention relates to a power system of a special vehicle based on a double-terminal output operation / travel drive motor. Background technique [0002] Existing pure electric special vehicles using the main and auxiliary dual-motor drive system, when in the working state, the main drive motor drives the traveling device of the main drive shaft of the special vehicle, and the auxiliary motor drives the operation device of the special vehicle for operation; in the non-operating state, the main drive motor The auxiliary motor of the traveling device that drives the main drive shaft of the special vehicle does not work; as the special vehicle operates at a low speed, 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 working state, when the special vehicle is running at high speed, accelerating rapidly, or climbing a steep slope, the main drive mot...
