Integrated hydraulic motor and winch

A hydraulic powered driven member assembly comprising:

• a support unit;
• a driven member rotatable about an axis relative to the support unit;
• a hydraulic motor responsive to receiving hydraulic fluid for rotating the driven member relative to the support unit;
• said hydraulic motor includes an inner gerotor rotor, an outer gerotor rotor, said inner gerotor rotor having a radially outwardly facing gerotor surface, said outer gerotor rotor having a radially inwardly facing gerotor surface radially opposed to said outwardly facing gerotor surface, said gerotor surfaces cooperatively defining variable volume gerotor fluid power chambers;
• said support including one support portion fixedly supporting said inner gerotor against rotational movement relative to said support unit, another support portion rotatably supporting said driven member for non-orbital rotational movement relative to said support unit;
• and said driven member supporting said gerotor outer rotor.

A hydraulic powered driven member assembly comprising:

• a fluid powered gerotor drive unit, a driven member, and a support assembly;
• said gerotor drive unit including an inner gerotor rotor fixed against rotational movement relative to the support assembly, an outer gerotor rotor, said inner and outer gerotor rotors including respectively outer and inner gerotor gear surfaces that cooperatively define variable volume gerotor fluid chambers, valve surfaces hydraulically connected to said fluid chambers supply fluid to and receive fluid from said fluid chambers;
• said outer gerotor rotor having a first drive link and said driven member having a second drive link, said first and second drive links engaging to transfer rotational torque and rotational movement from said outer rotor to said driven member;
• and said inner gerotor rotor and said outer gerotor rotor and said chambers all being disposed substantially entirely within said driven member.

A hydraulic powered driven member assembly comprising:

• an inner gerotor rotor, an outer gerotor rotor, a driven member, and a support assembly;
• said inner and outer gerotor rotors including respectively outer and inner gerotor gear surfaces that cooperatively define therebetween variable volume gerotor fluid power chambers;
• said inner gerotor rotor being fixed against movement relative to said support assembly;
• said outer gerotor rotor being mounted for rotational and orbital movement relative to said support assembly and relative to said inner gerotor rotor, said outer gerotor rotor having an exterior;
• said driven member being mounted externally of said outer gerotor rotor for non-orbital rotary movement relative to said support assembly and relative to said inner gerotor rotor, said driven member having an interior and an exterior surface;
• cooperating drive surfaces on said exterior of said outer gerotor rotor and on said interior of said driven member to transfer non-orbital rotational torque and rotational motion between said outer gerotor rotor and said driven member and to support said outer gerotor rotor within said driven member;
• and
• said external surface of said driven member moves in a non-orbital rotational path.
