Abstract: The present invention provides a transmission and clutch device of an electric chassis and the electric chassis. The transmission and clutch device includes a transmission shaft, a first drive shaft, a first compression spring, a first gear, a second compression spring and a second drive shaft successively along an axial direction, the first drive shaft and the second drive shaft are fixed together, the transmission shaft is provided for connecting to a motor, and the first gear is fixed on a base in a rotatable manner, wherein the first drive shaft is connected with the transmission shaft in a relatively sliding manner and can rotate synchronously along with the drive shaft; and two end faces of the first gear are each opened with a keyway for separably cooperating with a protrusion of an end face of the first drive shaft or a protrusion of an end face of the second drive shaft. The transmission and clutch device according to the present invention has a high modularization level and high interchangeability, and can be automatically switched rapidly and stably.
