Problems solved by technology

Therefore, the torque conversion range of the hydraulic torque converter is also limited, and the torque increase coefficient K≤8 (K=turbine torque / pump torque) Moreover, the hydraulic torque converter is a non-detachable whole, and special-purpose tools are required for maintenance. The equipment cuts and dissects it, and performs high-precision positioning and welding after maintenance. The process is difficult and demanding

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] In the accompanying drawings, the star gear torque converter is composed of planetary gear input shaft 1, planet carrier 2, planetary shaft 3, planetary gear 4, internal gear 5, sun gear 6 in row A; planetary gear internal gear 7 in row B, sun gear 8, The planetary gear shaft 9, the planetary gear 10, the planetary carrier 11, the output shaft 12, and the locking clutch 13 constitute; the number of planetary gears is between 3-12; the gears can be straight teeth, helical teeth or herringbone teeth.

[0023] In Fig. 1, the input shaft 1 inputs torque, and the input force is transmitted to the internal gear 5 and the sun gear 6 through the planetary carrier 2, the planetary shaft 3, and the planetary gear 4, and is decomposed into two forces of equal magnitude, and the internal gear 5 is transmitted to the internal The force of t...

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...
