Abstract
A robotic vehicle with a battery powered power take-off (PTO) shaft. A single battery powers a PTO motor that is directly connected to a torque converter with a PTO shaft output and two independent track motors.
Claims18
A robotic vehicle comprising:
- a battery unit;
- a motor controller electrically connected to the battery unit;
- a motor connected to the motor controller;
- a torque converter connected to the motor;
- and
- a power take-off (PTO) shaft extending from the gear box.
A robotic vehicle, comprising:
- a chassis comprising a right side and a left side;
- an operating unit positioned rearward on the chassis;
- a battery unit positioned forward on the chassis;
- a PTO motor controller electrically connected to the battery unit;
- a PTO motor connected to the PTO motor controller;
- a torque converter connected to the PTO motor;
- a PTO shaft extending from the gear box;
- a coolant system operably connected to the PTO motor controller and the PTO motor for dissipating heat from the PTO motor controller and the PTO motor;
- a right track assembly separable from the right side of the chassis;
- and
- a left track assembly separable from the left side of the chassis, wherein each of the right track assembly and the left track assembly comprise a track motor operably connected to a track.
The robotic vehicle of claim 13, wherein each torque converter further comprises a motor input gear coupled to the output of the PTO motor, an input idler gear coupled to the motor input gear, and a PTO output gear coupled to the input idler gear and coaxially coupled to the PTO shaft. The robotic vehicle of claim 14, wherein the torque converter further comprises an output idler gear coupled to the PTO output gear and an idler shaft axially coupled to the output idler gear.
The robotic vehicle of claim 15, wherein each torque converter further comprises a front plate, a mid-plate, and back plate to locate the motor input gear above the input idler gear and locate the PTO output gear adjacent to the input idler gear and locate the output idler gear above the PTO output gear.
