摘要:
An agricultural harvester rear axle arrangement for an agricultural harvester (10) having a body (12), the arrangement comprising left and right rear wheels (18, 20); means for supporting the wheels for rotation about a generally vertical steering axis (38, 40, 78, 94) and for supporting the wheels for extension and retraction from the body of the combine (26, 28, 30, 90); actuator means for steering the wheels (38, 40, 70, 72, 94) and for extending and retracting the wheels (34, 36, 70, 72); an electronic controller (50) coupled to the actuator means to steer, extend and retract the wheels.
摘要:
The present invention relates to an assembly which includes: a chassis for a mobile land vehicle, in particular an agricultural or public works vehicle; at least two half-crossmembers (21) mounted telescopically on the chassis; wheel mountings (27) pivotably mounted on each one of said half-crossmembers; steered wheels rotatably mounted on said mountings; and a device for controlling the direction of the wheels. The assembly is characterised in that it includes means (39, 41, 47) designed, for a certain position of two half-crossmembers, to increase, upon the pivoting of the wheels, the opening of the said wheels relative to the opening of the wheels resulting from the same pivoting and another position of the two half-crossmembers.

An extendible axle member (146 or 148) is provided for a pivoting axle of an agricultural harvester (100), the extendible axle member (146 or 148) having an elongate telescopic portion (400) with bearing surfaces for being slidably received in an outer axle member (142 or 144), wherein the elongate telescopic portion (400) is formed integral with and abuts a C-frame for supporting a steering knuckle (158 or 160).
摘要:
A bearing arrangement for an extendable axle of an agricultural harvester, the axle comprising an outer axle member (142,144) and an extendable axle member (146,148) telescopically supported in the outer axle member (142,144), the bearing arrangement comprising a first member (214,216) that is wedged between the outer axle member (142,144) and an extendable axle member (146,148) and a first bolt (300) passing through a first clearance hole (302) in a first sidewall (304) of the outer axle member (142,144) and threadedly engaged with the first member (216).
摘要:
A steering axle assembly (18) of a work machine such as an agricultural harvester (10) includes telescoping axles (30, 32) and wheel assemblies (24, 26) on the telescoping axles (30, 23), with front and rear hydraulic cylinders (50, 52, 70, 72) for axially and angularly adjusting positions of the wheel hub assemblies, including steering the hubs to angles sufficient to minimize a width of the steering axle assembly (18) for transport.

Eine Radachse für einen Mähdrescher umfasst einen Achskasten (2), zwei am Achskasten (2) befestigte Radaufhängungen (3) und zwei im Achskasten (2) angeordnete Schiebemodule für die Verstellung der Radaufhängungen (3). Jede Radaufhängung (3) weist einen Oberlenker (4), einen Unterlenker (5) und einen Getriebeträger (6) auf, wobei ein erstes Ende des Oberlenkers (4) am Achskasten (2) und ein entgegengesetztes Ende des Oberlenkers (4) am Getriebeträger (6) und wobei ein erstes Ende des Unterlenkers (5) am Achskasten (2) und ein entgegengesetztes Ende des Unterlenkers (5) am Getriebeträger (6) drehbar gelagert ist.
摘要:
Two-module, amphibious motor vehicle with two or more axles comprising, for each module, a central body, fixed to a base for a detachable, water-tight cabin, its lower part being connected to suspensions comprising transverse springs (12), whose outside and opposite ends are fixed to pairs of side members (9) of the vehicle. Alternatively, each spring is made up of two aligned half-springs slidably mounted in suitable guides; said half-springs can be blocked in their seat, in a desired position within prefixed limits, in order to vary the track of the wheel sets of each module (Figure 5).
