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 transmission comprises a transmission mechanism which comprises more than two gear sets, a first transmission shaft and a second transmission shaft, 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 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 gear shifting mechanism comprises a gear shifting assembly and a gear shifting control shaft, and the gear shifting assembly is in sliding connection with the gear shifting control shaft and used for controlling the gear shifting assembly to reciprocate. The gear shifting assembly comprises a gear shifting driving piece and a gear shifting joint piece, the gear shifting joint piece is rotatably installed on the gear shifting driving piece, and the gear shifting control shaft drives the gear shifting joint piece to be connected with or separated from the gears of the gear set in a lever transmission mode.
