The wheelchair has a front wheel (3) connected to an end of a cross-arm (21) through a plate (25) mounted on the end so as to rotate along a transversal and horizontal axis. The plate is connected to an equalizing bar (4) through a connecting rod (27) adapted to permit the transmission, to the plate, of the angle variation between the bar and the cross-arm. The equalizing bar is rotatably mounted on a central frame (2) and the support rear wheels. |
