Gas-electric hybrid engine

Abstract

The invention discloses a gas-electric hybrid engine, comprising an engine shell body, wherein a bent axle, a motor drive shaft, a main shaft, and a secondary shaft are arranged in the engine shell body; the bent shaft is driven to rotate by an internal combustor, and the upper peripheral direction of the bent shaft is fixed with a clutch, and a first active gear is fixed on the upper periphery of the output shaft of the clutch; the motor drive shaft is driven to rotate by the electric motor, and the upper periphery direction of the motor drive shaft is fixed with a second active wheel; a first overrun clutch, a second overrun clutch, a first driven gear, and a second driven gear are arranged on the main shaft; the inner ring of the first overrun clutch is fixedly connected with the peripheral direction of the main shaft; the outer rings of the first driven gear and the first overrun clutch are circumferentially and fixedly connected to each other, and often meshed with the first active gear; the inner ring of the second overrun clutch is fixedly connected with the main shaft in peripheral direction, and the second driven gear is fixedly connected with the outer ring of the second overrun clutch in peripheral direction, and often meshed with the second active gear; a transmission gear combination of the main and secondary shafts is arranged between the main and secondary shafts.

Description

technical field [0001] The invention relates to the field of engines, in particular to an oil-electric hybrid engine. Background technique [0002] Gasoline-electric hybrid tricycles or four-wheel vehicles have the advantages of high fuel economy and excellent driving performance, and their application prospects are widely optimistic and have been developed rapidly. [0003] However, the power of the gasoline-electric parallel hybrid drive system currently configured on tricycles or four-wheel vehicles cannot be switched freely. For example, when the electric motor power is output independently, the engine power must be cut off or the engine must be placed in neutral, otherwise It will drag the engine in reverse, drive the cylinder piston rod to continue to move, increase the motor load, and wear the cylinder piston rod; when the engine power is output independently, the motor power must be cut off before the switch can be completed, otherwise the motor will be reversed and ...

[0003] However, the power of the gasoline-electric parallel hybrid drive system currently configured on tricycles or four-wheel vehicles cannot be switched freely. For example, when the electric motor power is output independently, the engine power must be cut off or the engine must be placed in neutral, otherwise It will drag the engine in reverse, drive the cylinder piston rod to continue to move, increase the motor load, and wear the cylinder piston rod; when the engine power is output independently, the motor power must be cut off before the switch can be completed, otherwise the motor will be reversed and the engine load will be increased.

Moreover, since the electric motor cannot be adapted to the transmission system of the engine, the adaptation operation of the output power of the engine and the electric motor is complicated and the energy consumption is high, which greatly limits the scope of use of the gasoline-electric parallel hybrid drive system
