The A2FM series replaces the Rexroth hydraulic motor in production and is widely used in construction machinery such as excavators, concrete mixer trucks, concrete pump trucks, pump stations, pavers, and cranes.

Hydraulic Piston Motor characteristics:

1.High rated pressure, high speed, and high driving force;

2.The volumetric efficiency is about 95%, and the total efficiency is about 90%.;

3.Convenient variables and multiple formats;

4.Lightweight per unit power;

5.All major components are subjected to compressive stress, thus fully utilizing material strength performance;

6.Long service life under high pressure;

7.Low working sound;

8.Oblique design scheme;

Axial piston hydraulic motor:

The principle and structure of the axial piston hydraulic motor and the axial piston pump are basically the same, in addition to the valve style and flow distribution, the axial piston pump can be used as a hydraulic motor in principle, that is, the axial piston pump and the axial piston motor are reversible. The working principle of the directional plunger motor of the rotating center axis of the cylinder is that the oil distribution plate and the swash plate are stable and do not move, and the motor shaft and the cylinder body are connected to each other to rotate together. When the pressure oil enters the plunger check hole of the cylinder block through the form of the oil distribution pan, the plunger extends under the pressure oil and adheres to a normal reaction force p caused by the swash plate on the plunger. This force can be decomposed into an axial component and a vertical component Q. Q and the fluid pressure on the plunger are balanced, and Q allows the plunger to generate a torque against the center of the cylinder body, driving the motor shaft to rotate counterclockwise. The cylinder rotates the center axis in the direction of the plunger motor causing the instantaneous total torque to be pulsating. If the direction of the hydraulic motor pressure oil input is changed, the hydraulic motor shaft rotates in a clockwise direction. The change of the swash plate Angle a and the change of displacement not only interfere with the torque of the hydraulic motor, but also interfere with its speed and steering. The larger the inclination of the swash plate, the larger the torque and the lower the speed.
