CHASSIS DRIVE SYSTEM (VERSIONS) Russian patent published in 2018 - IPC B64C25/40 B64C25/50 

FIELD: transportation.

SUBSTANCE: drive system for rotating the wheel comprises an electric motor configured to rotate the first driving gear by the first gear and a driven wheel configured to be mounted to the wheel. Herewith the drive system has the first mode, in which the first driving gear engages the driven wheel to drive it by the electric motor through the first gear. Moreover, either the first driving gear or the driven wheel is made in the form of the first sprocket, and the other first driving gear or other driven wheel comprises a series of circumferentially spaced rollers, each of which is rotatable about its own axis. And each roller of the series is mounted with the ability to rotate around the pin. The drive system is configured to switch from the first mode to the third mode, in which the first driving gear is not engaged with the driven wheel.

EFFECT: increasing the reliability and stability to deformation of the wheel and deflection of axes between the driving and the driven wheels.
