Embodiment Construction

[0047] The sun gear 1 of the first stage can be used as a driving gear, while the sun gear 12 of the second stage can be used as a driven gear, or vice versa. The kinematic chain may be configured to integrate with another kinematic chain by mating any suitable gears.

[0048] The geared automatic transmission provides at least two power transfer streams. Such as figure 1 As shown in , a power transmission flow is external, from the sun gear 1, through the first planet gear 2 of the first stage, then through the sun gear 5 of the first stage and the sun gear 7 of the second stage (where the sun gear 5 and 7 are integral with each other), then the power transmission flow passes through the planetary gear 10 of the second stage, and finally to the sun gear 12, which is a driven gear;

[0049] The other power transmission flow is internal, from the sun gear 1, through the first planetary gear 2 of the first stage and the planetary gear 3 of the first stage (gear 3 is integral ...

Abstract

Two or more stages of planetary mechanisms are used as an automatic geared variator, which stages of planetary mechanisms comprise sun gears, a carrier and planetary gears which can be in the form of double wheel gears. The planetary mechanisms comprise two or more power transfer flows. In one of the structural embodiments, the carrier of the first stage can be formed in one piece with the sun wheel gear of the second stage, the sun wheel gear of the first stage can be formed in one piece with the carrier of the second stage and the transmission ratio is changed without disengaging gears and without using control devices by initially stopping at least one link or placing it in a position close to the stop position, depending on the equality or closeness of forces of different power flows which are opposite in terms of the orientation thereof and which are transmitted thereto from different sides and from the main power flow links which are divided by the kinematic chains and depend on the load, relations between the diameters of the gears, center-to-center spacing determined by the number of teeth thereof and modules, and owing to the mobility of such a link which depends on the change in load, forces, the circular and relative velocity of the links in such a way that such an equality is recovered by the tendency of the forces to balance and to the restoration of the initial equilibrium position of the links.

Description

technical field [0001] The invention relates to the mechanical engineering industry and can be used in other industries for driving machines and mechanisms; in particular, the invention can be used as a geared automatic transmission without control equipment with continuously variable gear ratios without the need for disengaging gears. [0002] The present invention has no analogs. Background technique [0003] Known types of gearing (including planetary gears, differentials, corrugations and other types of gearing) do not allow automatic change of gear ratios without control equipment without disengaging the gears (cf. ".. машиностроение.:., 1977; ю.н.кирдяшев" многопоточные передачидифференциального типа типа ".л.: Машиностроение, 1981; а.крайнев" механика машин.фундаментальный словарь ".м.: Машиностроение, 2000). Contents of the invention [0004] It is therefore an object of the present invention to provide a geared automatic transmission without a control device capa...
