The invention discloses a power coupling box for a fuel-electric hybrid power system. The power coupling box comprises a box body (6), wherein a first shaft (1) and a second shaft (2) are rotationally arranged on the box body (6) respectively and provided with input ends; at least one of the first shaft (1) and the second shaft (2) is provided with an output end; a first gear (3) and a second gear (4) which are meshed with each other are arrange on the first shaft (1) and the second shaft (2) respectively; and at least one of the first gear (3) and the second gear (4) is arranged on the first shaft (1) or the second shaft (2) by an overrunning clutch (5). When a motor is switched on, a driven gear and a driving gear are subjected to meshing transmission. When the rotating speed of the driving gear is lower than that of an installation shaft, the motor is in a free motion state. When the rotating speed of the driving gear is higher than that of the installation shaft, the motor assists a heat engine to draw a load together. By using the power coupling box for the fuel-electric hybrid power system, impact and vibration which are generated by the hybrid power system can be effectively reduced or avoided when the motor is switched on.
Description
technical field [0001] The invention relates to a power coupling box of a hybrid power system, in particular to a power coupling box of an oil-electric hybrid power system. Background technique [0002] A gasoline-electric hybrid system usually includes two power sources: a heat engine (diesel engine or a gasoline engine) and an electric motor. The output power of the heat engine and the output power of the electric motor must be coupled to drive the load. When the hybrid system is working, the heat engine usually works stably in the fuel-consumption economy zone, and the electric motor is in two states of on and off according to different working conditions. When the electric motor is turned on, if the electric motor is directly connected to the hybrid power system, due to the high speed of the heat engine, it is easy to cause shock and vibration, which will affect the normal operation of the hybrid power system. Therefore, it is necessary to design a power coupling devic...
