TRANSPORT SYSTEM INDEPENDENT POWER TAKEOFF SHAFT DRIVE Russian patent published in 2001 - IPC

Abstract RU 2162798 C2

FIELD: tractor engineering. SUBSTANCE: drive has pump and two-step reduction gear. First step of reduction gear is made in form of three-member differential mechanism, gear ratio i= K+1/K, and second step, in form of planetary train, gear ratio I=1+K where K is planetary train characteristic. One member of planetary train is coupled with pump. Pressure main line of pump includes check valve and throttling regulator. Such design of drive provides maintaining of preset speed of power takeoff shaft at variable loads and operation of engine at high speed. EFFECT: simplified design of drive. 2 cl, 2 dwg
