Zusammenfassung: | A vehicle transmission with multiple gear ratios includes a spur-gear gearbox with a first spur gear and a second spur gear arranged on a spur-gear shaft, wherein the first spur gear meshes with a fourth spur gear and the second spur gear meshes with a third spur gear, and an epicyclic gear train with a first and a second epicyclic gear sets and a epicyclic gear train shaft. Each of the epicyclic gear sets has a ring gear and at least one epicyclic gear, and at least one of the epicyclic gear sets has a sun gear and at least one planet carrier. A gear box, the spur-gear shaft and the epicyclic gear train shaft are rotatably mounted relative to the gear box. A plurality of speed changing devices are provided, wherein the first spur gear can be selectively connected in a torque-transmitting manner to the spur-gear shaft. The vehicle transmission is characterized in that the first spur gear can be selectively connected in a torque-transmitting manner to the gear box, at least one of the sun gears can be selectively connected in a torque-transmitting manner to the gear box, and the third spur gear can be selectively connected in a torque-transmitting manner to one of the planet carriers. |
