Gear arm assembly

A vehicle comprising:

• a frame;
• at least one power source mounted to the frame;
• a drivetrain mounted to the frame and connected to the at least one power source;
• at least four gear arm assemblies mounted to the frame and connected to the drivetrain, each gear arm assembly of the at least four gear arm assemblies comprising:
• a gear arm housing having a first end, a second end, and an intermediate portion, the gear arm housing from the intermediate portion to the first end defining a first arm segment, and the gear arm housing from the intermediate portion to the second end defining a second arm segment;
• a plurality of gears meshed together in series and housed within the gear arm housing, the plurality of gears including an intermediate gear within the intermediate portion of the gear arm housing;
• a first wheel hub connected to a first gear of the plurality of gears at the first end of the gear arm housing;
• a second wheel hub connected to a second gear of the plurality of gears at the second end of the gear arm housing;
• a primary drive shaft extending into the gear arm housing at the intermediate portion and configured to connect the drivetrain to the intermediate gear;
• a spindle housing configured to connect the gear arm assembly to the frame;
• and
• a spindle rotatably coupled to and within the spindle housing and configured to allow for rotation of the gear arm housing relative to the spindle housing;
• a plurality of wheels, each wheel of the plurality of wheels being connected to the first wheel hub or the second wheel hub of a separate one of the at least four gear arm assemblies,
• wherein the drivetrain is configured to drive the plurality of wheels of the gear arm assemblies of the at least four gear arm assemblies on a first side of the vehicle independently from the wheels of the gear arm assemblies of the at least four gear arm assemblies on a second side of the vehicle, opposite from the first side.

A gear arm assembly for a vehicle comprising:

• a gear arm housing having a first end, a second end, and an intermediate portion, the gear arm housing from the intermediate portion to the first end defining a first arm segment, and the gear arm housing from the intermediate portion to the second end defining a second arm segment;
• a plurality of gears meshed together in series and housed within the gear arm housing, the plurality of gears including an intermediate gear within the intermediate portion of the gear arm housing;
• a first wheel hub connected to a first gear of the plurality of gears at the first end of the gear arm housing;
• a second wheel hub connected to a second gear of the plurality of gears at the second end of the gear arm housing;
• a primary drive shaft extending into the gear arm housing at the intermediate portion and configured to connect a drive input to the intermediate gear;
• a spindle housing configured to connect the gear arm assembly to the vehicle;
• and
• a spindle rotatably coupled to and within the spindle housing and configured to allow for rotation of the gear arm housing relative to the spindle housing.
