The invention relates to a variable transmission (3) for an electric vehicle and comprising a variator unit (40) for providing a continuously variable speed ratio between an input shaft (44) and an output shaft (45) thereof. According to the invention, the variable transmission (3) further comprises two planetary gear sets (50) respectively provided on a respective axial side of the output shaft (45) and each comprising three coaxially rotatable members (51, 52, 53) including a sun gear (51), a ring gear (52) and a planet carrier (53) rotatably carrying planet gears (54), whereof first members (51, 52, 53) rotate as one with the output shaft (45), whereof second members (51, 52, 53) respectively rotate as one with a respective one of the two driven wheels (2) and whereof third members (51, 52, 53) of each of the planetary gear sets (50) are connectable to a stationary part (39) of the variable transmission (3) via a respective clutch (55).
摘要:
The disclosure relates to a hydropower generator, and more particularly to a hydropower generator which has a compact and simple structure, efficiently generates electric energy by arranging multistage blade assemblies along a flow path of a fluid, and not only improves power generation efficiency but also is easily installed and dramatically lowers installation costs because the arrangement position and the number of blade assemblies are properly adjustable according to flow amount, flow rate, designed capacity and local conditions. The hydropower generator according to the disclosure includes: a driving shaft installed along a path through which a fluid flows; a plurality of blade assemblies installed along a lengthwise direction of the driving shaft; a spinning supporter connected to rotatably support the driving shaft; a power generator receiving a spinning force of the driving shaft and generating electricity; and a flow pipeline internally provided with the driving shaft along a lengthwise direction thereof and formed with a channel through which a fluid flows.
