摘要： A robust ground traction (drive) assembly for remotely controlled vehicles, which not only operates smoothly on surfaces that are flat, but also upon surfaces that include rugged terrain, snow, mud, and sand, is provided. The assembly includes a sun gear and a braking gear. The sun gear is configured to cause rotational force to be applied to second planetary gears through a coupling of first planetary gears. The braking gear is configured to cause the assembly (or the second planetary gears) to rotate around the braking gear when an obstacle or braking force is applied.

摘要： A torque transmission device includes an engine, a motor, an output shaft, and a planetary gear mechanism. The engine and the motor generate driving torque, and the output shaft outputs the driving torque. The planetary gear mechanism includes a first rotating element rotating together with the engine, a second rotating element connected to the motor, and a third rotating element connected to the motor.

摘要： A manually controlled semi-automatic, multiple-step, internal gear driven transmission characterized by a hydraulic activation system of compensating fluid pressure versus spring compression resistance forces including a forward section having an integrated dual clutch and pinion carrier, driven by an engine shaft, a gear-type oil pump driven by helical gears supplying the servo-system, a rear section pinion carrier, related die cast pinion gear clusters, annulus gears and an interconnecting middle section dual-annulus gear. The gear ratio changes are effected by annulus fluid-combination spring power cylinder brake control and fluid actuated clutches capable of causing the transmission of torque to a load shaft directly through a main shaft, through the rear pinion carrier or through the dual annulus, whereby the least reduction is obtained when all elements are in operation. The invention is further characterized by a variable pressure regulator, governing actuating fluid pressure at idling speeds, and a differential-piston pressure regulator, governing main line fluid pressure at all speeds, to a directory rotary distributor valve feeding said power cylinders and clutches as directed by a manual straight line shifting arrangement, said regulators having a compensating fluid pressure versus spring compression design.

摘要： A hydrodynamic-mechanical transmission for automobiles comprises a torque converter, a planetary gear train and connecting devices associated with the gear elements. The planetary gear train includes two simple planetary sets connected by means of a common sun gear. The connecting devices include (1) a forward clutch connecting the turbine shaft of the torque converter with the ring gear of the first planetary set, (2) a direct and reverse clutch coupling the turbine shaft with a clutch housing, which surrounds the forward clutch and is connected with the sun gear, (3) a band brake acting on the clutch housing, (4) a multipledisk brake actuated by a cylindrical piston and acting on the planet carrier of the second planetary set and (5) an overriding brake likewise acting on the planet carrier. The first planetary set, the forward clutch, the clutch housing and the cylindrical piston are arranged concentrically with each other.
