The A36VM axial piston variable motor from Bosch Rexroth was developed for drivetrains. It allows greater tractive force and speed for mobile machines.
Today, ever faster and more flexible mobile machines are needed. Whether they are on the road or on site - construction machinery, agricultural machinery and municipal vehicles can be used more economically if they have greater tractive force and speed. What was only possible in the past with gear shifting is now easily possible with the new axial piston variable motor from Bosch Rexroth. The A36VM is based on the proven A6VM motor, but was optimized specially for the challenges posed by drivetrains.
Two new features make the A36VM the ideal solution for electronically controlled hydrostatic drivetrains: Firstly, Bosch Rexroth has managed to increase the swiveling range to up to 38°. Secondly, the maximum pressure has been raised to 530 bar. As a result, machines can reach a speed of up to 40 km/h without having to increase the speed of the diesel engine or integrate a complex shift gearbox.
The A6VM from Bosch Rexroth, which has proven itself for more than 30 years, serves as the basis for the new A36VM axial piston variable motor. This has been specially modified and improved to meet the needs of drivetrains. The swiveling range was increased – with a nominal size of 125 cm3 it is 5-38°, while 5°-36° is possible with a nominal size of 255 cm3. The shifting of valves makes the A36VM more efficient, which now also features fewer sealing points. Furthermore, the geometry was optimized in close consultation with axis and vehicle manufacturers. The outer dimensions as well as the position of the valves and sensors enable the system to fit seamlessly into tight spaces and existing vehicle architectures.
