Embodiment Construction

[0038] To facilitate understanding of the present invention, the drawings are not drawn to scale. The figures show only one half of the vehicle, which extends symmetrically about the axis XX', which represents the longitudinal median plane of the vehicle.

[0039] figure 1 is a schematic illustration of a vehicle half 1 according to the invention with six tires arranged on the two axles 5 , 6 , two of said tires on the front axle 5 being steerable tires. Since only the vehicle half is shown in the figure, only three tires 2, 3, 4 are shown.

[0040] exist figure 1 The vehicle 1 schematically shown in is a heavy vehicle with a gross payload of 800 metric tons.

[0041] The tire 2 equipped on the front axle is a large tire with a ratio of section height to width H / S of 0.50, H is the height of the tire on the rim, and S is the tire when the tire is installed on the rim and inflated to the recommended pressure maximum axial width. The size of this tire is 100 / 59R69.

Abstract

The invention relates to a heavy vehicle, such as a transport vehicle or a 'civil engineering' vehicle, of a mass greater than 500 metric tons, fitted with tires of radial structure of a diameter greater than three meters fifty, and comprising a front axle provided with at least two tires and at least one rear axle comprising at least two tires and by which is transmitted at least part of the motive power. According to the invention, at least one of the axles comprises at least four tires associated in pairs symmetrically on either side of the axle, two associated tires having different axial widths.

Description

technical field [0001] The present invention relates to a heavy vehicle such as a transport or "civil engineering" vehicle weighing more than 500 tonnes and fitted with tires having a diameter greater than 3.5 metres. Background technique [0002] Such vehicles are generally designed to carry heavy loads and comprise a front steered axle with two steered wheels and a rear axle, both generally rigid, with four drive wheels arranged in pairs on either side. [0003] A bridge is defined as the group of elements that enables the fixed structure of a vehicle to be connected to the ground. [0004] The axial or transverse direction of the tire is parallel to the axis of rotation of the tire. [0005] The circumferential direction or longitudinal direction of the tire is the direction corresponding to the outer circumference of the tire and is defined by the rolling direction of the tire. [0006] The axis of rotation of the tire is the axis about which the tire rotates in normal...
