Abstract:
Presented is a heavy vehicle, such as a transport vehicle or civil engineering vehicle, of a mass greater than 500 metric tons and operable to generate a motive power. The vehicle includes tires of radial structure having a diameter greater than 3.5 meters, a front axle coupled to at least two tires, and at least one rear axle coupled to at least two tires and by which is transmitted at least part of the motive power. At least one of the axles includes at least four tires associated in pairs symmetrically on either side of the axle, and two associated tires have different axial widths.
Abstract:
Presented is a heavy vehicle, such as a transport vehicle or civil engineering vehicle, of a mass greater than 500 metric tons configured to carry heavy loads and operable to generate a motive power. The vehicle includes tires of radial structure having a diameter greater than 3.5 meters and an axial width greater than 37 inches, a front steering axle coupled to at least two tires, at least one rear axle coupled to at least two tires and by which is transmitted at least part of the motive power, and a third, intermediate axle coupled to at least two tires. The intermediate axle is a steering axle and is moveable to a raised position. When the intermediate axle is in the raised position, the tires coupled to the intermediate axle are not in contact with the ground.
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.

Abstract:
A locking system for a ring for mounting on a hub of a vehicle, the mounting ring being intended to receive a bead of a tire in an assembly for mounting the tire on the hub of a vehicle. The locking system comprises a locking ring and a polymeric insert.
Abstract:
A heavy vehicle of a mass greater than 40 metric tons and operable to generate a motive power is disclosed. The vehicle includes a first axle, at least two first tires mounted on the first axle, a second axle for transmitting at least part of the motive power, and four second tires mounted on the second axle. At most two of the second tires are driving or motive power transmitting tires. Each of the second tires is associated with a respective braking device.

Presented is a heavy vehicle, such as a transport vehicle or a civil engineering vehicle, of a mass greater than 500 metric tons. The vehicle is fitted with tires of radial structure having a diameter greater than 3.5 meters and an axial width greater than 37 inches. The vehicle has a front steering axle provided with at least two tires and at least one rear axle provided with at least four tires for transmitting at least part of motive power. The rear axle has at least two trailing arms each associated with two tires.
Abstract:
A wheel rim includes a collar and a seat separate from the collar. Betweenhe collar and a bead, there is provided, axially in the mounting plane, a clearance which facilitates the mounting of the bead on the inside of the edges of the wheel rim. Then, the seat is inserted which eliminates the mounting clearance and keep the bead centered in relation to the wheel rim.
Abstract:
A locking ring for a ring for mounting on a hub of a vehicle, the mounting ring being intended to receive a bead of a tire in an assembly for mounting the tire on the hub of a vehicle. The locking ring comprises a polymeric envelope and an incompressible reinforcing element, the two elements being separable.
Abstract:
A device for fixing a module to the internal wall of a tire. This device includes a support secured to the tire and of a flexible strip, the support including means for fixing said strip, the ends of the strip having at least two independent means for attaching the module, and the strip having means for immobilizing the module.
