DRIVE SYSTEM FOR AGRICULTURAL MOBILE POWER EQUIPMENT Russian patent published in 2013 - IPC B60K31/02 B60W30/188 

FIELD: transport.

SUBSTANCE: invention relates to agricultural machinery and is intended for ganging up with agricultural machines. Proposed system is equipped with hydraulic displacement transmission with control component. Said hydraulic displacement component comprises hydraulic pump driven by mobile power equipment engine, means to couple power takeoff shaft with hydraulic motor shaft, and device to allow automatic maintenance of rpm. Hydraulic pump is hydraulically communicated with hydraulic motor. Continuously variable-ratio hydraulic displacement drives of two power takeoff shafts and drive axles are equipped with the system of servo devices. Said system of servo devices consists of rpm transducers and servo mechanisms. Said rpm transducers and servo mechanisms are electrically connected with onboard computer. Servo mechanisms control rpm of rotors of driven hydraulic pumps and hydraulic motors via mechanical hinged-lever links. Onboard computer has appropriate vehicle speed control program.

EFFECT: stable faultless operation and efficiency.
