The inventive motorised wheel chair comprises propelling and control means. Said propelling means consist of a motor actuating a first hydraulic pump which is serially connected to a first hydraulic circuit feeding a receiving hydraulic motor (24b) from a tank, said motor being connected to a left wheel (4b), a second hydraulic pump serially connected to a second hydraulic circuit feeding a receiving hydraulic motor (24d) which is connected to a right wheel (4d) which is transversally mounted to the right of said left wheel (4b). Said wheel chair also comprises a spool pilot unit actuated by a lever disposed between the hydraulic circuits and the tank in such a way that it is possible to control a hydraulic fluid feeding of the hydraulic receiving motors (24b, 24d) of the left (4b) and/or right (4d) wheels. The front wheels (4b, 4d) are rotated by axle ends pivotally mounted around a vertical axis. Two pivots (51b, 51d) are connected to each other by means a coupling shaft (53) with the aid of steering levers (52b 52d) which are connected to the pivots (51b, 51d). |
