Two-speed transmission for an electrically powered motor vehicle; as well as motor vehicle

摘要

The invention relates to a two-speed transmission (1) for an electrically driven motor vehicle (30), having a first shaft (2) forming a transmission input, a second shaft (4) coupled or capable of being coupled to an output (3), and two gear stages (5, 6) that differ in their transmission ratio and are used between the two shafts (2, 4), with a first gear stage (5) having a first fixed wheel (7), a first gear meshing with the first fixed wheel (7). Has a loose wheel (8) and a freewheel device (9) that acts between the first loose wheel (8) and the shaft (2) receiving the first loose wheel (8), and wherein a second gear wheel stage (6) has a second fixed wheel (10), a second idler wheel (11) meshing with the second fixed wheel (10) and a friction clutch (12) operatively inserted between the second idler wheel (11) and the shaft (2) receiving the second idler wheel (11), and further for converting a reverse gear to practice The bridging clutch (13) designed and arranged for bridging the freewheel device (9) is used to act between the first idler gear (8) and the shaft (2) receiving the first idler gear (8), which bridging clutch (13) is activated by an externally controllable actuating device (14) is adjustable between its closed position and its open position. The invention also relates to a motor vehicle (30) with this two-speed gearbox (1).
