Adjustable bogey beam support for utility vehicles

A utility vehicle comprising:

• a frame;
• a rear axle supported from the frame and having a pair of wheels mounted thereon;
• a steering axle having a pair of steered wheels pivotally mounted thereon;
• a middle axle having a pair of support wheels mounted at opposing ends thereof;
• a longitudinally extending bogey beam having a longitudinal length extending between a forward end supporting said steering axle and a rearward end supporting said middle axle;
• and
• a pivot assembly connecting said bogey beam to said frame, said pivot assembly defining a transverse pivot axis about which said bogey beam is pivotable, said pivot assembly being selectively mountable at one of multiple predetermined positions along said longitudinal length of said bogey beam.

In a utility vehicle having a frame supported by a steering axle having a pair of steered wheels pivotally mounted thereon, a rear axle supported from the frame and having a pair of wheels mounted thereon, and a middle axle having a pair of support wheels mounted at opposing ends thereof, the improvement comprising:

• a longitudinally extending bogey beam pivotally connected to the frame and having a forward end and a rearward end, said steering axle being connected to said forward end of said bogey beam and said middle axle being connected to said rearward end of said bogey beam;
• said middle axle being pivotally connected to said bogey beam such that said middle axle is independently movable relative to said bogey beam about a longitudinally extending axis, thereby allowing said middle axle to oscillate in a generally vertical plane relative to said frame;
• and
• said bogey beam is pivotally connected to said frame by a pivot assembly defining a transverse pivot axis about which said bogey beam is pivotable, said pivot assembly being selectively mountable at one of multiple predetermined positions along a longitudinal length of said bogey beam.
