Abstract
Present reaction arms for use with an endless belt fail to adequately disperse the debris from the drive wheel and the endless belt. The present reaction arm includes a cushioning member interposed a first end and an outer surface of a center portion of a hub assembly. And, the reaction arm includes a second end being attached to a chassis of a work machine. The reaction arm is axially positioned within a pair of sides of an endless belt and is generally centered along an axis defined by the pair of sides.
Claims16
A work machine comprising:
- a chassis;
- an engine having a transmission and a final drive operatively connected and attached to the chassis;
- a pair of endless belts positioned on each of a side of said work machine and being operatively driven by said engine, transmission and final drive, said pair of endless belts defining an inner surface and a pair of sides;
- a pair of drive wheels being drivingly and axially movably attached to said final drive on each of said sides of the work vehicle, each of said drive wheels having a rotatable hub assembly defining a pair of driving disks being spaced apart forming a cavity therebetween;
- and
- a pair of support assemblies each having a first end being attached to the corresponding hub assembly and having a cushioning member interposed said first end and said corresponding hub assembly, and a second end being attached to the chassis, said first end of the support assembly being positioned between the pair of sides of individual ones of the pair of endless belts.
A system for attaching an endless belt to a work vehicle, said endless belt includes a pair of sides and an inner surface being defined between said pair of sides and said work vehicle includes a chassis and a driving apparatus operatively attached to said chassis, said system comprising:
- a rotatable hub assembly having a driving disk operatively attached to the driving apparatus and being spaced from the chassis, said driving disk including a pair of driving portions being separated by a preestablished space;
- a support assembly having a first end being attached to the hub assembly and having a cushioning member interposed said first end and said corresponding hub assembly, and a second end being attached to the chassis, said first end of the support assembly being positioned within the preestablished space and within the pair of sides of the endless belt.
