Problems solved by technology

[0002] The stability and load response of the power system including the prime mover (such as the transmission parts including the motor and the engine) are very important, which not only affect the noise, vibration, life and efficiency of the system, but also affect the pollution emission of the system when the engine is included. The traditional solution is to add a rotating inertial body (such as the flywheel of the engine) at the power output end of this type of power system. This solution will not be conducive to the torque distribution of the prime mover power shaft, and it will cause certain difficulties to the space layout, especially in the This is especially true in solutions that include a variable ratio mechanism

Abstract

The present invention discloses a power system. The power system comprises an engine, a power shaft, an impeller A, an impeller B, a speed changer and a hydraulic pump, wherein the power shaft is configured to be a power output shaft of the engine, the impeller A and the impeller B are in series connection arrangement, the power shaft and the impeller A are in transmission arrangement, the power shaft and the speed changer are in transmission arrangement, the impeller B and the hydraulic pump are in transmission arrangement, and inertia bodies are arranged on the impeller B, on a transmission component between the impeller B and the hydraulic pump and / or on a transmission component of the hydraulic pump. The power system provided by the invention is advantageous by being simple in structure, high in efficiency, good in load response and excellent in environmental protection performance, scientifically distributing the torque of the power shaft of a prime motor, and providing flexibility for spatial arrangement.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a power system. Background technique [0002] The stability and load response of the power system including the prime mover (such as the transmission parts including the motor and the engine) are very important, which not only affect the noise, vibration, life and efficiency of the system, but also affect the pollution emission of the system when the engine is included. The traditional solution is to add a rotating inertia body (such as the flywheel of the engine) at the power output end of this type of power system. This solution will not be conducive to the torque distribution of the prime mover power shaft, and it will cause certain difficulties to the space arrangement, especially in the This is especially true in solutions involving variable ratio mechanisms. Therefore, a new power system needs to be invented. Contents of the invention [0003] In order to solve t...
