Abstract

The invention discloses a power transmission system. The power transmission system comprises a power input shaft and a flywheel, wherein the power input shaft and the flywheel are in transmission through a ratio changing device which adopts a fluid ratio changing device, an electromagnetic ratio changing device or a mechanical ratio changing device. The power transmission system has good load response and is energy-saving and environment-friendly, and power of a power system can be efficiently used.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a power transmission system. Background technique [0002] The power system with frequent load changes, such as the power system of internal combustion engine-driven excavators, loaders, bulldozers, etc., the engine speed changes drastically, which not only affects the life and efficiency of the engine, but also must use a high-horsepower engine to meet the peak of the system Power requirements, which have caused serious waste and environmental emissions. Therefore need to invent a kind of novel power transmission system. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] Solution 1: A power transmission system, including a power input shaft and a flywheel, and the power input shaft and the flywheel are set through a transmission ratio device. [0005] Solution 2: On t...
