HST 28 cm³/r (Hydraulic Static Transmission ) for conbine harvester

How it works:
Power device drive the piston pump to convert mechanical energy; then hydraulic energy converts into mechanical energy through piston motor to provide torque for executive component.Piston pump and motor constitute closed loop,leaked oil be supplied by cycloid boost pump.Piston motor output shaft drive the running device to realize the machine's forward,stop,back functions.

Application and features on the combine harvester:
1.operate easily;Harvester with WHPVMF can fulfill retreat,commutation and stable stepless speed change by operating a pedallever.
2.Useful:regarding hydraulic pumps,motors ,valves .WHPVMF are doing all-in-one right with light weight . it not only easy to realize all-wheel drive,power output and pulse width modulation,but also can add variety of electronic control device achieve electrification,improving harvester performance.
3.Flexibility: Harvester with the WHPVMF can walk in a very small turning radius with a very show speed,it can turn or go in and out the site flexibility.
4.High efficiency:WHPVMF's unique designreduce weight,shorten pipenline,lower power consumption,improve
the efficiency,its overall efficiency is up to 80%;According to different conditions,load and harvester grain
number,stem thickness,moisture content,WHPVMF changes oblique plate Angle,adjusts the flow and the
output torque to make harvester operate more efficiently.
