Abstract
Disclosed herein is a gear train of a multi-step transmission for a vehicle, which can shift gears among nine forward speeds and one reverse speed. The gear train realizes a desired level of multi-step change gear ratios and has a reduced number of sets of planetary gears to reduce the volume and length of the transmission, thus realizing a compact structure, thereby facilitating the installation of the transmission in the vehicle.
