  • Patent number: 7344145
    Abstract: A compressed air treatment device is designed to be installed in an industrial vehicle consisting of a motor vehicle that can pull a trailer. The device comprises: an inlet for air from a compressed air source; at least one air outlet which is connected to a tank that is intended to supply the service braking system; a set of electropneumatic components for distributing the compressed air which comes from the compressed air source and which is intended for the tank(s); an electronic control unit which can control said set of electropneumatic components, the control unit being connected to a computer communication bus and to various electrical components such as sensors or switches.

  • Patent number: 7036805
    Abstract: A pneumatic front suspension assembly for an industrial vehicle comprises: a front axle linked to a pair of side-members, and a pair of airbags for adjusting the height of the axle relative to the side-members. On each side, there is provided a rigid arm whereof one end is articulated relative to the side-members, and the other end receives the axle and the lower part of the suspension air bags; a pair of connecting rods mutually articulated about a pin substantially parallel to the axle, one of said connecting rods, the upper connecting rod, being articulated relative to the side-member, the other connecting rod, the lower connecting rod, being articulated relative to the rigid arm, and a generally U-shaped additional element, forming an anti-roll bar, and including a transverse rod linked to the lower connecting rods at their articulation points with the rigid arms, and branches located on either side of the transverse rod, and linked to the lower connecting rods.

  • Publication number: 20040261404
    Abstract: The invention concerns an internal combustion engine exhaust line comprising an active noise reduction system with variable choke device, continuously regulated based on the instantaneous discharge rate pulses of exhaust gases exiting from the internal combustion engine, including an expansion chamber for closing phases of the variable choke device arranged upstream of said active noise reduction system and a cavity dispersing medium and high frequencies arranged downstream of the active noise reduction system. The expansion chamber for the closing phases of the variable choke device is integrated in a first depolluting system arranged upstream of said active noise reduction system.

  • Publication number: 20040260441
    Abstract: The invention relates to a method of controlling a compressor which is driven by the engine of a vehicle and which supplies at least one compressed air tank. The compressor is activated or de-activated according to a comparison which is made between the value of the pressure in the tank(s) and the pre-determined conjunction and disjunction pressure thresholds, depending on the sign of the engine torque. If the range of torque is positive there are multiple conjunction and disjunction pressure thresholds which are determined according to the vehicle speed estimation or measurement.
