Embodiment Construction
[0075] figure 1 with 2 is a schematic illustration of a vehicle 1 constructed in accordance with the invention comprising a front axle 2 comprising four tires 4a, 4b, 5a, 5b arranged in pairs, and a rear axle 3 carrying three rear arms 6 , 7, 8, and includes six wheels distributed in pairs on the three arms 6, 7, 8
[0076] Tires 9a, 9b, 10a, 10b, 11a, 11b.
[0077] exist figure 1 The vehicles schematically indicated in are dump-type heavy vehicles with a fully loaded weight exceeding 1000 tons.
[0078] The various tires installed on this car are large tires with an aspect ratio H / S equal to 1, where H is the height of the tire on the rim when the tire is mounted on its working rim and inflated to its recommended pressure, and S is the largest axis of the tire to the width. The size of the tires is 44R69.
[0079] These tires comprise a radial carcass reinforcement composed of inextensible steel metal cables, oriented radially and fixed in each bead of the tire.

Abstract
The invention relates to a heavy vehicle, such as a transport vehicle (1) or a civil engineering vehicle, having a mass greater than 500 tons, fitted with tires of radial construction (4a, 4b, 5a, 5b, 9a, 9b, 10a, 10b, 11a, 11b), including a steering front end assembly (2) and a rear end assembly (3), and the steering front end assembly (2) includes at least two tires (4a, 4b, 5a, 5b), the rear end assembly (3) comprises at least four tires (9a, 9b, 10a, 10b, 11a, 11b) through which at least part of the drive power is transmitted. The invention is characterized in that the rear end assembly (3) comprises at least two rear arms (6), each rear arm having two tires.
Description
technical field [0001] The invention relates to a heavy vehicle, such as a transport vehicle or a "civil engineering" vehicle, having a mass greater than 500 tons and fitted with tires with a diameter greater than 3.5 meters and an axial width greater than 93.98 centimeters (37 inches). Background technique [0002] Such vehicles, usually designed to withstand heavy loads, consist of a front steered axle comprising two steered wheels and a rear axle which is usually rigid and comprises four drive wheels distributed in pairs on each side. [0003] An axle is defined as an assembly of elements that connect the stationary structure of a vehicle 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 of the tire, or longitudinal direction, is the direction corresponding to the circumference of the tire and is defined by the rolling direction of the tire. [0006] The axis of r...
