Planetary gear torque converter

Abstract

The invention provides a planet-gear torque converter, solving the technological default of hydraulic torque converter. Dual planetary gear system is made of A, B two individual planet-gear rows and locking clutch. The torque on inputting shaft is transmitted to inner gear and central gear of planet-gear and divided into two same forces, which is transmitted to inner gear and central gear of another planet-gear row respectively. By changing the gear number of central gear or inner gear of anther row (single or double), one force is controlled more than another. Larger force is active force and in the same direction with inputting power. Smaller force is passive force and in the reverse direction with inputting power. Planet-gear rotates with the revolution and autogiration, meanwhile the speed of revolution is decreased and output torque is enlarged. The invention is provided with no fire damage, simple and compact structure, stable working and so on.

Description

technical field [0001] The present invention relates to mechanical torque converters, and more particularly, to a planetary gear torque converter. Background technique [0002] The hydraulic torque converter used in automobiles is a continuously variable transmission that can automatically change the torque conversion coefficient as the driving resistance of the vehicle changes. The hydraulic torque conversion is realized through the torque conversion of the guide wheel. The liquid drives the turbine to rotate at high speed and high pressure from the pump wheel, and at the same time, when the liquid flows from the turbine to the guide wheel, it gives an impact force to the guide wheel, and the guide wheel passes through the liquid to give the turbine a reactionary impact force, which increases the torque of the turbine and makes the torque of the output shaft Can be greater than the input shaft torque. When the speed of the pump wheel is constant, the torque of the output s...
