Abstract

The invention relates to a shifting device for a multi-speed transmission of an electric vehicle, which includes a shifting unit and a parking unit, the shifting unit controls shifting through the torque of the actuator, and the parking unit controls the shifting through the torque of the actuator Control the parking state. Specifically, the actuator includes a control motor that transmits drive torque to the first driven gear and the second driven gear through a drive gear that is externally meshed with the driven gear, and the shift unit includes: a shift fork that slidably mounted on the fork rail and actuating shifting; a profile roller connected to a first driven gear externally meshing with the drive gear and having a profile groove formed along the outer periphery of the profile roller; and a shift guide block, It is integrally formed with the shift fork and is coupled with the contoured groove.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2018-0142796 filed on November 19, 2018, the entire contents of which are incorporated herein by reference for all purposes. technical field [0003] The invention relates to a shifting device for a multi-speed transmission of an electric vehicle. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] An automatic manual transmission (AMT), a dual clutch transmission (DCT) or a multi-speed transmission for an electric vehicle is generally applied to apply an automatic shift gear having a gearing to a gearing of a conventional manual transmission. Such a transmission is usually provided with a park actuator for automatic parking, and a shift actuator for automatic gear shifting. [0006] Multi-speed transmissions for electric veh...
