Beschreibung
Zusammenfassung:	The utility model provides a speed change device, a vehicle driving system and a vehicle, and relates to the technical field of vehicle speed change, the speed change device comprises a first transmission gear set, a second transmission gear set, an overrun clutch and a gear shifting mechanism, the gear ratio of the second transmission gear set is smaller than that of the first transmission gear set; the first transmission gear set is connected with the overrun clutch, the second transmission gear set is connected with the gear shifting mechanism, the overrun clutch and the gear shifting mechanism are used for being connected with a transmission shaft of a vehicle, and the overrun clutch is used for enabling the first transmission gear set to run in a load or idle mode. The gear shifting mechanism is used for combining or separating the gears of the second transmission gear set with or from the transmission shaft. The gear shifting device has the advantage of being capable of preventing power interruption dur
