The invention provides a heavy vehicle comprising at least four mounted assemblies, each one consisting of a wheel and a tyre, and intended to draw machinery. The vehicle is designed such that the properties thereof satisfy the relationshipwhere ρ'=ρ/L, ρ being the turning radius of the vehicle and L being the wheelbase of the vehicle, κ is the proportion of the total vertical stiffness under the front axle with respect to the sum of the total vertical stiffnesses under the front and rear axles of the vehicle, δ is the ratio between the forward offset of the centre of gravity and the wheelbase L, h' is the ratio between the height of the draft line above the level of ground that forms a horizontal plane and the wheelbase of the vehicle, μ is the ratio between the longitudinal component of the resistive force applied by the drawn machinery to the vehicle, and the weight of the vehicle. |
