ABSTRACT:
The combination of a hydraulic torque converter and planetary gear system in a wheel hub characterized in that the selective speed control of an individual wheel is achieved through the hydraulic torque converter, thereby obviating the need of gear shifting as in the anterior combinations. This hydraulic torque converting wheel includes a spindle, a tight casing rotating on the spindle and sealed relative to the latter, a rim surrounding the casing and forming a wheel hub therewith, a planetary gear system including an input gear, a planet carrier, planet gears and a first and a second output gears, torque converting blades and fins mounted inside the rotatable casing, the input gear drives the planet carrier and the planet gears which drive the blades through the first output gear and the casing through the second output gear; the blades drive the casing by torque converting cooperation with the fins, and a selective speed control is connected to the blades to rotate the latter relative to the fins and thus change the torque converting relationship therewith.
