Compact two-speed transmission for an electrically driven motor vehicle

摘要

Transmission (3) for an electrically driven motor vehicle which, together with an electric motor (2), forms a drive unit (1) integrated in a drive train, which comprises a planetary gear as the transmission (3) with an associated differential (6) and a gear shift (5) , wherein the transmission (3) is connected to drive wheels of the motor vehicle via at least one output shaft, characterized in that the transmission (5) includes a spindle shaft (11) that can be activated via an actuator (10) to produce a quickly shiftable transmission (3), which interacts directly with a synchronizing device (4) of the transmission (3), which is modularly constructed as a two-speed transmission and includes two planetary gear sets, the spindle shaft (11) of the gear shift (5) being connected directly to a shift fork (20) of the synchronizing device (4), wherein the shift fork (20) limits an axial movement of a sliding sleeve (19) and by means of a fixing pin Ftes (21) prevents rotation of the sliding sleeve (19) with a synchronizer hub (12).
