Embodiment 1
[0027] A damping type valveless hydraulic synchronous servo system, which uses a valveless system combined with a servo motor and a variable pump to drive multiple hydraulic cylinders arranged on a valveless hydraulic parallel synchronous circuit, and sensors are used on each parallel branch to monitor the speed, Pressure and displacement are used for data collection, and the controller compares and analyzes the data; in each parallel branch, the hydraulic cylinder on the first branch is the target cylinder, and the hydraulic cylinders on the other branches are follower cylinders, and the cylinder head of the follower cylinder is added There is a friction resistance device, through which the movement speed of the output ends of each cylinder is adjusted to realize the synchronization of displacement, speed and pressure.
[0028] The frictional resistance device includes a gear pressing block mechanism and a V-shaped sealing ring. The gear pressing block is connected to the cyli...
