The invention belongs to the technical field of transmissions, and particularly relates to a center shaft transmission, a center motor and a vehicle. The center shaft speed changer comprises a transmission mechanism, the transmission mechanism comprises more than two gear sets, a first transmission shaft and a second transmission shaft, each gear set comprises gears meshed with each other in pairs, the gears of the gear sets are arranged on the first transmission shaft and the second transmission shaft respectively, and the transmission mechanism has at least two transmission ratios; the input assembly is connected with the first transmission shaft and used for inputting torque to the first transmission shaft; the output assembly is connected with the gear set and used for outputting torque; the gear shifting mechanism is used for switching different gear sets to work so as to change the transmission ratio of the transmission mechanism; the one-way clutch is arranged between the first transmission shaft and/or the second transmission shaft and the gears of the gear set, the structure of the gear shifting mechanism is simplified, the gear shifting mechanism is easy to control, and meanwhile the weight and the size of the center shaft transmission are greatly reduced.
