DEVICE TO DECREASE RIGIDITY OF VEHICLE TRANSMISSION Russian patent published in 2004 - IPC

FIELD: transport engineering; agricultural machinery. SUBSTANCE: proposed device contains planetary gear train whose reactive link is connected with oil pump driver gear, oil pump is connected to suction and delivery main lines, planetary gear train is connected with gearbox by carrier shaft and two-stage adjustable throttle is installed in delivery main line with safety valve and control valve being connected to throttle input. Damper valve is connected in parallel with throttle. Hydraulic tank and pneumatic accumulator are also provided. Damper valve consists of sleeve, plunger, spring adjusting screw relief channel. Pneumohydraulic accumulator, being end member of delivery mainline, consists of hydraulic cylinder and free piston. Movable weights made in form of one-side hydraulic cylinder are installed together with spring into gear of oil pump drive. Inner spaces of weights are connected through oil channel and oil line with weight position regulator. EFFECT: decreased influence of vibrations of external traction load onto efficiency of vehicle under different operating conditions. 2 dwg
