Abstract
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).
Claims8
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 the extendable axle member (146,148);
- 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);
- a second member (214) that is wedged between the outer axle member (142,144) and the extendable axle member (144, 146);
- and
- a second bolt (320) that passes through a second clearance hole in a second sidewall (312) of the outer axle member (142, 144) and is threadedly engaged with the second member (214),
- wherein the outer axle member (142,144) has a first planar surface (212), wherein the first member and the second member each has a planar surface that rests on the first planar surface (212) of the outer axle member (142,144) and is coplanar therewith.
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 the extendable axle member (146,148);
- 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);
- a second member (214) that is wedged between the outer axle member (142,144) and the extendable axle member (144, 146);
- and
- a second bolt (320) that passes through a second clearance hole in a second sidewall (312) of the outer axle member (142, 144) and is threadedlv engaged with the second member (214),
- wherein the first member (216, 214) and the second member (216, 214) are elongated and extend in a direction parallel to a longitudinal extent of the outer axle member (142, 144) and a longitudinal extent of the extendable axle member (146,148) and further wherein a plurality of first bolts (300) and second bolts (320) spaced apart in the longitudinal direction along the length of first and second members (216,214).
