F-HPVMF-18-R-02 Hydrostatic Transmission for Combine Harvester,hydraulic system parts

Product Description
The product consists of main pump, motor, charge pump and valves. During working period, the main pump is driven by the motor to produce the hydraulic pressure through changes of piston and rotor cubage. The motor is provided with hydraulic pressure power by the hydraulic pressure pump. The principal axis is driven to rotate through interaction of the motor rotor and piston, which is transformed to mechanical energy to supply torques for the controlling elements.
The product has features of compact structure, small volume, high efficiency, light weight, long service life and low noises. It is mainly applied to the walking drive system of combine harvester and mini type engineering machine.
