Network optimization information:

Its core components are basically the same as A2F pump/motor, and its variable mechanism components and variable mode are basically the same as A7V constant power variable pump. The minimum swing angle of TJVW5 variable speed motor cylinder is 7 °, and the swing angle is 25 °. Common variable methods include high-pressure automatic variable (HA) and hydraulic control variable (HD). The high pressure automatic variable automatically controls the displacement of the motor according to the working pressure. The hydraulic control variable changes the output torque and speed of the motor by externally controlling the pressure of the hydraulic oil to control the angle change of the motor, so as to achieve the purpose of changing the displacement, output torque and speed of the motor.

For ease of understanding, assume that there is only one plunger with a certain taper (half taper angle is a). When the drive shaft starts to rotate, 2K hydraulic cycloid motor The side of the plunger does not contact the inner wall of the cylinder cavity, but only makes the plunger move axially. Axial flow distribution cycloidal hydraulic motor When the transmission shaft rotates at a certain angle, the side of the plunger contacts the inner wall of the cylinder cavity, and the plunger rotates with the cylinder block. When the transmission shaft rotates by an angle p, the rotation angle of the cylinder block is 0. The difference of y=9-0 is called angular difference. When the transmission shaft is at a different angle o, the contact position between the plunger side and the inner wall of the cylinder cavity is different, and the angle difference is also different. In fact, the oblique axial piston pump has Z (usually z=7) and plunger. Therefore, when working, each plunger contacts the inner wall of the cylinder cavity in turn, pushing the cylinder block to rotate, and only needs to overcome the friction torque.
