<p>A human powered land vehicle has two steered front wheels (3, 3.1) and at least one rear wheel (2) driven by a drive train. The drive train incorporates a human powered actuator (13) to be actuated for propulsion of the vehicle (1) by a person driving the vehicle (1). This actuator (13) is cinematically coupled to the rear wheel (2) for propulsing the vehicle in at least one driving direction. A first suggestion is defined—in that the axis A3 of the human powered actuator (13) is arranged in the longitudinal extension of the vehicle (1) in front of the axis A1, A11 of rotation of the front wheels (3, 3.1),—in that three dimensions are defined in the x-y plane of the vehicle, which are (a) a distance d1 between the centre B of rotation of the axis A2 of the rear wheel (2) and the centre D of rotation of the axis A3 of the human powered actuator (13), (b) a distance d2 between the centre A of rotation of the axis (A1, A1.1) of the front wheel (3, 3.1) and the intersection point C of a line connecting the centre A with the x-axis of the vehicle (1) the connecting line being perpendicular to the x-axis of the vehicle (1), and—(c) a distance d3 between the centre B and the intersection point C, whereas distance d1 has a value of 1235 mm±15%, distance d2 has a value of 1 132 mm±15%, and distance d3 has a value of 379 mm±15% and—in that the ratio between the squared distance AB2 between the centre B and the centre A and the squared distance AD2 between the centre A and the centre D is within the range between 2.8 to 15.3. According to another suggestion the ratio of the distance of the front wheels (3, 3.1) from each other measured in the height of their axis A1, A1.1 of rotation and the diameter of the front wheels (3, 3.1) is in the range from about 1.3 to about 1.7. The axis A3 of the human powered actuator (13) is arranged between the two front wheels (3, 3.1) within their projection to each other in the traverse direction of the vehicle (1) and in the vertical direction above the axis A1, A1.1 of rotation of the front wheels (3, 3.1) and in the longitudinal extension of the vehicle (1) in front of the axis of rotation of the front wheels (3, 3.1).</p> |
