Abstract
A machine (100) includes a frame that is pivotally connected to a tandem drive arrangement. The tandem drive arrangement includes a beam (120) and a first motor (128) having a first stator portion (202) connected to a first end of the beam (120). The first motor (128) also includes a first rotor portion (204) connected to a first drive wheel (118). A load sharing arrangement (412) is associated with the tandem drive arrangement and includes a first collar (414) rotatably disposed around the first stator portion (202) and a second collar (426) rotatably disposed around a portion of the beam (120). A first linkage (424) is pivotally connected between the first and second collars such that the load sharing arrangement (412) balances unbalanced loading in the tandem drive arrangement by transferring the unbalanced loading to the frame.
