Abstract:
A pneumatic control system for a heavy-duty vehicle includes an air supply in fluid communication with a height control valve and an air spring. An air lock valve is in fluid communication with the height control valve and the air spring, and is also in fluid communication with a blank cavity. The air lock valve includes an "air lock off" position and an "air lock on" position. When the air lock valve is in the "air lock off" position, fluid flows from the height control valve, through the air lock valve to the air spring. When the air lock valve is in the "air lock on" position, fluid communication between the air spring, the air lock valve and the height control valve is prevented and, instead, fluid flows from the air spring, through the air lock valve to the blank cavity.

Abstract:
The invention relates to a tipping haul body such as a tipping trailer (10). The tipping trailer (10) includes at least one axle (12) and a tub base (40). The tub base (40) is arranged to support the load of a payload receiving tub (20) of the trailer (10) and to transmit that load via the at least one axle (12) to a ground surface. The tub base (40) and the tub (20) are arranged to be connected together and to pivot together about a pivot axis (P 1 ) when the trailer (10) is activated to dump a payload from the tub (20). The invention also relates to a tipping and suspension unit for a haul body such as trailer or a dolly.
Abstract:
The invention refers to a lift axle control valve assembly (1) for a lift axle suspension system, said lift axle control valve assembly (1) comprising: a pneumatic spool valve (4) for adjusting the air volume. of at least a suspension bellow (14) and a lift bellow (16), a pressure differential valve (9) for controlling said spool valve (4), an electrically actuated pneumatic valve device (7, 8) for receiving at least one electric control signal (S1, S2) and for controlling said pressure differential valve (9), and a relay valve (10) controlled by said pneumatic spool valve (4), wherein said lift axle control valve assembly (1 ) comprises a multilayer construction with at least two valve levels and at least two layers comprising air passages (11 a, 11 b, 11c, 11d, 11e 11f, 11g, 11 h, 11 k) for conducting air, wherein said valve levels are separated by at least two layers, wherein said valves (are positioned in said valve levels an connected with each other by said air passages (11) of said layers.
Abstract:
A wheel axle suspension for a vehicle comprises on both sides of the vehicle a trailing arm which extends in the longitudinal direction of the vehicle, a thin walled tubular axle body, which has attachment regions where the axle body is attached to the trailing arms. Each trailing arm is hingedly connected at the front, viewed in the direction of travel of the vehicle, to a bearing bracket which is arranged on the vehicle chassis. The suspension also comprises a pneumatic spring which is operational between each of the trailing arms and the chassis. The wheel axle suspension furthermore comprises clamp bodies for clamping the axle body at the attachment regions thereof so as to attach the axle body to the trailing arms, as well as tensioning elements for providing the clamp force for the clamp bodies. The clamp bodies engage the axle body over a certain longitudinal distance of the attachment region and around virtually its entire circumference. The axle body has a substantially circular cross section in the clamping regions and is provided with an elongated indent in each of the clamping regions. The indent extends in a longitudinal direction of the axle body. At least one of the clamp bodies is provided with a protrusion that engages in the elongated indent.
Abstract:
Es wird ein Magnetventil vorgeschlagen, das ein umlaufendes Außengehäuse (322) und ein umlaufendes Innengehäuse (324) aufweist, die so aneinandergrenzen, dass eine erste Ventilöffnung und eine zweite Ventilöffnung ausgebildet werden. Das Außengehäuse weist mindestens eine äußere Durchgangsöffnung (340) auf, die über einen ersten Fluidkanal mit der ersten Ventilöffnung verbunden ist. Das Innengehäuse weist mindestens eine innere Durchgangsöffnung (342) auf, die über einen zweiten Fluidkanal mit der zweiten Ventilöffnung verbunden ist. Das Magnetventil weist ferner ein erstes und ein zweites Verschlusselement (344) auf, die beweglich angeordnet sind, um ein Verschließen und Öffnen der ersten und zweiten Ventilöffnung zu ermöglichen. Ferner weist das Magnetventil eine elektrische Spule (320) auf, die so zwischen dem Außengehäuse und dem Innengehäuse angeordnet ist, das das Außengehäuse, das Innengehäuse, das erste bewegliche Verschlusselement und das zweite bewegliche Verschlusselement jeweils Teilabschnitte eines Magnetkreises ausbilden, wenn durch die Spule ein elektrischer Strom fließt. Trotz eines großen möglichen Öffnungsquerschnitts kann damit eine für elektrische Schaltventile außergewöhnlich kurze Öffnungszeit erreicht werden, da zum einen die bewegte Masse der Ringscheibe (344) vergleichsweise gering ist, während gleichzeitig der Überdruck im Ringspalt das Ventil beschleunigt öffnet, noch bevor das magnetische Feld aus der Spule (320) abgeführt ist.
Abstract:
An elastomeric spring suspension is described for supporting a longitudinally extending vehicle frame rail above first and second axles forming a tandem axle configuration. The suspension includes a frame hanger assembly mounted to the vehicle frame rail. The frame hanger assembly has two full spring modules, each of which includes two shear springs, a progressive spring rate load cushion having a pyramidal shape with a flattened top surface and a spring mount for mounting the springs. A saddle assembly is connected to the spring mount, and an equalizing beam is connected to the saddle assembly and further connected to the axles. The spring rate for the suspension increases almost linearly as a function of sprung load, resembling a pneumatic suspension. Accordingly, the suspension exhibits excellent ride quality, without sacrificing roll stability.
Abstract:
A method of monitoring a vehicle (10) using a sensor to measure a parameter which depends on the forces acting on the vehicle (10) generally normal to the surface over which the vehicle is travelling, transmitting a force signal from the sensor to a processing apparatus (16), the processing apparatus (16) processing a plurality of said force signals to determine a value indicative of the forces acting on the vehicle generally normal to the surface over which the vehicle (10) is travelling over a specific period of time.
