Gearbox that can be shifted under load

Abstract

Gearbox (100) with a housing (1), with an input shaft (2) for coupling a mechanical power and with an output shaft (3) for coupling the mechanical power, wherein the speed of the output shaft (3) is variable relative to the speed of the input shaft (2) in switching stages and under load, and comprising at least one planetary stage (5, 6) comprising several components at least a sun gear (13), a planetary bridge (14, 17) and a ring gear (15, 16, 18), where - a power branch (4) is provided which is designed to branch the couplingable mechanical power to at least two different components of the planetary stage (5, 6), - wherein switching elements (7, 9, 11) are arranged such that the input wave (2) as part of the power split (4) can be selectively engaged with the at least two different components of the planetary stage (5, 6) by means of the switching elements (7, 9, 11), - wherein the first component of the planetary stage (5, 6) forms the sun wheel (13), to which the coupling-in mechanical power can be transferred by means of the power split (4), characterized by that the output shaft (3) is connected to the ring gear (15, 16, 18) of the planetary stage (5), wherein the planetary bridge (14, 17) can be fixed to the housing (1) by means of a switching element (10), wherein at least one switching element (7-12) is designed as an electro-hydraulically or electro-mechanically controlled wet multi-plate clutch or multi-plate brake, wherein at least one switching element (7-12) is designed as an electro-hydraulically or electro-mechanically controlled dog clutch, wherein the switching elements (7, 9, 11) connected to the input shaft (2) interact with the switching elements (8, 10, 12) connected to the housing (1), such that - the switching element (7, 9, 11) connected to the input shaft (2) opens when the switching element (8, 10, 12) connected to the housing (1) closes, and / or - the switching element (7, 9, 11) connected to the input shaft (2) closes when the switching element (8, 10, 12) connected to the housing (1) opens.
