A Hydraulic Servo Actuater Cylinder for Performance Test Equipment of Transmission

摘要

The present invention relates to a cylinder for a hydraulic servo actuator used in a test apparatus for testing the endurance performance of a vehicle transmission.;In the case of the present invention, the material of the cylinder is made of aluminum alloy to reduce the weight while improving the structure of the inner piston structure and the cylinder cover on both sides, thereby reducing sliding resistance and greatly reducing the number of parts required for airtightness between the piston rod. It is possible to solve the difficulty of control by inertia during the reciprocating operation of the piston inside the cylinder, so that it can be used more effectively in the field of test equipment for testing the performance of the vehicle transmission and widely adopted in the general hydraulic cylinder field. to be.
