Abstract:
The invention relates to a heavy-load vehicle (100) comprising at least two partial vehicles, namely a frontmost partial vehicle (102) and a rearmost partial vehicle (104), said frontmost partial vehicle (102) having connecting means (118), and said rearmost partial vehicle (104) having counter-connecting means (128) adapted and configured for cooperating with said connecting means (118), one of said connecting means (118) and said counter-connecting means including an inner telescopic member (118c) guided in a hollow outer telescopic member (118d) in a telescoping manner. According to the invention said hollow outer telescopic member (118d) is integrally formed by a tubular or box-shaped central part of a partial vehicle frame (112) of one (102) of the partial vehicles, said hollow outer telescopic member (118d) and said inner telescopic member (118c) cooperating therewith being parts of the same partial vehicle (102).
Abstract:
A fifth wheel control arrangement (100) for an articulated vehicle comprising a fifth wheel having a biased hinge joint and an actuator (115) arranged to control a biasing force and/or a damping force of the biased hinge joint. The control arrangement comprises a control unit configured to automatically control the actuator in response to one or more input sensor signals associated with a current state of the articulated vehicle, to obtain a target wheel axle load of the articulated vehicle and/or to stabilize the articulated vehicle.
Abstract:
A semi-trailer (4) for transporting a load (2) to be moved has a wheeled front module (6) having a right-hand front row (15) and a left-hand front row (16) of front bogies (12) each provided with a respective hydraulic suspension (20) driven by its own hydraulic cylinder (21); a wheeled rear module (7) comprising a right-hand rear row (18) and a left-hand rear row (19) of rear bogies (13) each provided with a respective hydraulic suspension (20) driven by its own hydraulic cylinder (21); a coupling unit of the wheeled front module (6) for the coupling to a tractor (3) and comprising a pair of hydraulic jacks (27) for transferring a part of the load to be moved to the tractor (3); a first hydraulic unit (31) interposed between the hydraulic cylinders (21) of the front (15; 16) and rear rows (18),(19) of bogies and configured in such a way that the sum of the instantaneous load-supporting pressures acting on the hydraulic cylinders of the right front row (15) and of the cylinders of the left-hand rear row (19) is equal to the sum of the instantaneous pressures controlling the cylinders of the left-hand front row (16) and of the cylinders of the right rear row (18); and a second hydraulic unit (31) configured to control the hydraulic jacks (27) based on the sum of the instantaneous load-supporting pressures acting on the hydraulic cylinders (21) of said right front row (15) and of said left-hand front row (16).
Abstract:
A three-axle semi-trailer (16) comprising a chassis (2) with a lowered portion, and a tilting tank (18) at least partially supported by said lowered portion, characterized in that the edge of the tank (18) is provided with twist locks (10) cooperating with corner blocks (12) of conventional containers (14, 22, 24) at least partially resting on said edge.
Abstract:
Present invention makes it possible to discharge the air in suspension bellows (6) of a trailer used in intermodal freight transportation, when it is being loaded on a train, without the need for operator input, incorporating pneumatic roller valves (1) that are connected to each other in series, activating the system that will discharge the air in suspension bellows (6) by sending a signal once they are connected to the hooks of the crane lifting the trailer to be loaded on the train, a pneumatically induced valve (2), keeping the air discharge system that is activated by connecting both of the pneumatic roller valves (1) to the hooks of the crane, to be active continuously, a solenoid pneumatic valve (3) to deactivate the air discharge system that is kept active continuously and an air induced pneumatic valve (4) allowing the air that is compressed in the bellows to be discharged to the atmosphere.
