Abstract

A hydraulic motor includes a rotor supporting a plurality of piston elements projecting away from opposing faces of the rotor. The rotor is adapted to rotate about a first axis. The hydraulic motor further includes a pair of drum plates each supporting a plurality of cup elements. The plurality of cup elements are adapted to engage the piston elements. Each drum plate is arranged on an opposing side of the rotor and is adapted to rotate about a second axis in angled relation to the first axis. Each of a pair of swashplates is in operative engagement with a respective one of the drum plates and each is adapted to pivot relative to the rotor to move with the respective drum plate between a maximum displacement position and a minimum displacement position to thereby change the angled relation between the first axis and the second axis. The pair of swashplates are further independently pivotable between three different settings.
