Product Name: HST Hydraulic Static Transmission for Combine Harvester
INTRODUCTION
This product consists of main pump, motor, oil pump and valves. When it works, prime motor drives main pump to make hydraulic energy by volume changing between plungers and rotors. Hydraulic pump provide energy to motor meanwhile the work between rotor and plunger drive main shaft rotating. Then it offer the mechanical energy to execute component.Our HST have more compact structure,smaller size,lighter weight,higher efficiency,longer life and less noise .It is mainly used in driving system of combine harvester and miniature construction machine.
