Abstract
A hydraulic fluid system is disclosed herein. The hydraulic fluid system includes a hydraulic motor including an output shaft, a reduction gear box having a first side and an opposing second side, the reduction gear box being coupled to the output shaft at the first side and coupled to a reduction shaft at the second side, and a magneto-rheological fluid brake (MRF) brake coupled to the reduction shaft.
Claims18
A hydraulic fluid system, comprising:
- a hydraulic motor including an output shaft;
- a reduction gear box having a first side and an opposing second side, the reduction gear box being coupled to the output shaft at the first side and coupled to a reduction shaft at the second side, wherein the output shaft has a first diameter and the reduction shaft has a second diameter, the second diameter being smaller than the first diameter;
- and
- a magneto-rheological fluid (MRF) brake coupled to the reduction shaft.

A hydraulic fluid system, comprising:
- a hydraulic motor having a first output shaft;
- a gear box having a second output shaft, the gear box being coupled to the first output shaft, wherein the first output shaft has a first diameter, wherein the second output shaft has a second diameter, and wherein the first diameter is larger than the second diameter;
- and
- a magneto-rheological fluid (MRF) brake having a third output shaft, the MRF brake being coupled to the second output shaft.
1 more element
A hydraulic fluid system, comprising:
- a hydraulic motor configured;
- a reduction gear assembly including an input gear coupled to a first shaft and an output gear operatively coupled to the hydraulic motor via a second shaft, the first shaft having a first diameter, and the second shaft having a second diameter that is less than the first diameter;
- a magneto-rheological fluid (MRF) brake operatively coupled to the hydraulic motor through the reduction gear assembly;
- and
- a controller configured to control a braking torque of the MRF brake to manage a speed of the hydraulic motor.
