The invention belongs to the technical field of internal transmissions, and particularly relates to an internal speed change hub and a vehicle. The internal speed change hub comprises a mandrel, a transmission mechanism, a driving mechanism, a gear shifting mechanism, an input part and an output part, the mandrel is fixed to a vehicle frame, and the driving mechanism, the gear shifting mechanism and the transmission mechanism are sequentially connected and all installed on the mandrel; the input part is fixedly connected with the transmission mechanism and used for inputting torque to the transmission mechanism. The output part is connected with the transmission mechanism and used for outputting the torque to wheels; the transmission mechanism has at least two transmission ratios. A cavity is formed in the inner side of a transmission mechanism of the inner speed change hub, a driving mechanism is installed on the side close to the planetary gear with the smallest tooth number in at least two planetary gears, or the driving mechanism is installed on the side close to the sun gear with the largest tooth number in at least two sun gears. The driving mechanism is installed in the cavity formed by the transmission mechanism, so that the whole inner speed change hub is more compact in structure and smaller in size.
