Large Control Range Hydraulic Wheel Motor Static Pressure Balance Structure
A6VM Series Rexroth Hydraulic Variable Motor And Part A6VM80 For Construction Machinery
Features:
Rexroth A6V hydraulic piston motor
Large control range with hydrostatic transmission
Cost-saving due to the possibility of using smaller pumps
High efficient
Due to the elimincetion of gear shifts, and the possibility of using smaller pumps, the product is cost saving. Meanwhile , it offers high power density, high efficiency, good starting performance, and low moment of interia. The variable displacement motor additionally has high axial loading capacity.
