The group of inventions relates to an electric tricycle, to a unit for transforming the frame of an electric tricycle and to a system for steering an electric tricycle using a joystick. The electric tricycle comprises a driving and a driven wheel (wheels), a rechargeable battery unit, a completely enclosed cab, a steering system, and a unit for transforming the frame, which makes it possible to dynamically change the distance between the front and rear wheels. The steering system comprises a steering mechanism and an electric motor, a joystick which transmits signals to a steering controller, which sends these signals to controllers of electric traction motors and to the electric motor, controllers of electric traction motors, and steering wheel position sensors, wherein signals from said sensors are read by the steering controller for controlling the functionality of the steering. The unit for transforming the frame comprises a filled cylinder with bidirectional action having a piston with a rod mounted in said cylinder so as to form working cavities, fixing elements, a connecting pipe which connects the cavities of the cylinder on the left and the right of the piston, and an electromagnetic valve, which stops the flow of liquid into the connecting pipe. |
