摘要:
An air supply control arrangement for a heavy-duty vehicle comprising a lift axle comprises: a brake valve device (36) which allows, when open, pressurized air to be passed to the brake chamber of the lift axle; a pressurized air source (46) supplying pressurized air to the brake valve device along a supply passage (44); a pilot control valve (32) provided between the pressurized air source and the brake valve device which restricts air flow through the supply passage; and a pressure-responsive element (52) which moves the pilot control valve into its closed state when the pressure in the lift bellow is increased so that the lift axle is raised to a lift condition, and which moves the pilot control valve into its open state when the pressure in the lift bellow is reduced so that the lift axle is lowered to a ride condition.

An agricultural baler (10) includes a hydraulic circuit (66) with a first hydraulic cylinder (74) connected between the first end (68) of the first axle (62) and the chassis (11), and a second hydraulic cylinder (78) connected between the second end (70) of the first axle (62) and the chassis (11). At least one sensor (94) senses a position of the chassis (11) relative to the first axle (62). An electrical processing circuit (96) is coupled with the hydraulic circuit (66) and the at least one sensor (94). The electrical processing circuit (96) controls operation of the hydraulic circuit (66), and includes an operator input device (108) for selectively: 1) raising the chassis (11) of the baler (10) relative to the first axle (62), 2) lowering the chassis (11) of the baler (10) relative to the first axle (62), or 3) automatically returning the chassis (11) of the baler (10) to a predetermined operating height relative to the first axle (62), dependent upon an output signal from the at least one sensor (94).

A vehicle including a body, a first and second swing arm assembly each pivotally mounted to the body, at least one wheel support arm pivotally mounted to the first swing arm assembly, an axle coupled to the wheel support arm, a wheel hub pivotally mounted to the axle, the wheel hub rotatably supporting at least one wheel in use, a support member pivotally mounted to the second swing arm assembly and either the wheel support arm or the first swing arm assembly. At least one steering arm pivotally connected to the support member and coupled to the wheel hub, wherein the steering arm, wheel support arm, and the support member are provided in a substantially triangular arrangement, a steering input pivotally mounted to the body and a steering coupling for connecting the steering arm to the steering input.

Die Erfindung betrifft ein mechanisches Stabilisierungssystem für Tandemachsen, Drillings- und/oder Vierlingsachsen im Kraftfahrzeugbau mit zwei, drei oder vier hintereinander angeordneten, am Fahrzeugaufbau (5) beweglich gelagerten radtragenden Achsen (11,12) oder Achsteilen. Dazu weist jede Achse pro Radseite eine gelenkig gelagerte Koppelstange (21-24) auf. Pro Fahrzeugseite sind die Koppelstangen paarweise mit einer Wippe (31,32) gekoppelt. Die Wippen stützen sich an den freien Ende eines U-Stabilisators (40) ab. Mit der vorliegenden Erfindung wird ein mechanisches Stabilisierungssystem für Tandemachsen, Drillings- und/oder Vierlingsachsen entwickelt, bei dem die Gewichtskraft des Fahrzeugaufbaus und die auf diesen Aufbau wirkenden Seitenkräfte unabhängig voneinander am Fahrwerk abgestützt werden.

A wheel suspension system having under powered acceleration a squat response that begins in the realm of anti squat and passes through a point of lessened anti squat at a further point in the travel.
摘要:
A balance suspension system for a vehicle having a body and at least four wheels (FR, FL, BR, BL) independently supported for movement between upper and lower positions relative to the body, the suspension system includes a balance mechanism adapted to support suspension forces in the vehicle and a plurality of actuating elements (73, 74, 78, 79) which are responsive respectively to the positions of the wheels relative to the body and are operable on spaced apart points on the balance mechanism. The system also includes control means for controlling relative movement between the balance mechanism and the body. The control means act to redistribute suspension forces between the body and the wheels, thereby to induce predetermined suspension behaviour.
摘要:
Anstatt bei einer Anfahrhilfe zur Traktionserhöhung bei geringem Reibwert an einem Fahrzeug mit einer entlastbaren Achse die Steuerung der Achslastverlagerung auf der Basis von Drücken in Luftfederbälgen der Antriebsachse und der entlastbaren Achse des Fahrzeugs vorzunehmen, wird entsprechend der Erfindung diese Achslastverlagerung auf der Basis von aktuellen Achslast-Gewichtskräften an diesen Achsen durchgeführt. Dadurch wird die Abhängigkeit der Anfahrhilfen-Traktionserhöhung von der Niveauhöhe des Fahrzeugs beseitigt und es wird eine sich üblicherweise mit der Niveauhöhe ändernde Hub-/Tragkraft-Charakteristik von Luftfederbälgen bei der Achslastverlagerung berücksichtigt.
