Compared with prior art, novel dual damping Liquid and gas damper have it is following the utility model has the advantages that
1. Double damping, effect is stronger.
Double damping refers to: piston rod band piston moves back and forth in resisting medium, and resisting medium flows through on piston Damping structure generates damping force;Resisting medium flows through the damping structure on pedestal simultaneously, generates damping.
Specific buffer process damping working principle is as shown in Fig. 2, piston rod is pushed away together by external force and piston Enter cylinder body, at the same time, resisting medium flows through the damping structure on piston, while resisting medium flows through the damping knot on pedestal Structure, resisting medium generates Double damping effect by the damping structure of two positions of piston and pedestal when process.
Damping reduces when damping structure opening increases, and is suitable for high speed light loading operating condition, when opposite damping structure opening reduces Damping increases, and is suitable for low-speed heave-load operating condition.Different operating conditions can be matched by adjusting the damping openings of sizes of damping structure to want It asks.
Since the damping structure flow on piston is larger, and the damping structure flow on pedestal is relatively small, so high speed Damping structure opening on the operating condition lower piston of underloading should be greater than the opening on pedestal damping structure;Under the operating condition of low-speed heave-load, Damping structure opening on piston should be less than the opening on pedestal damping structure.
Fig. 2 buffer process damps operation schematic diagram
Buffer resets damping working principle as shown in figure 3, gas chamber D discharges interior expansion, and promotion separator piston is moved out It is dynamic, resisting medium is entered into the room B from C chamber pressure by the damping structure on pedestal, at the same time, piston rod is damped medium and releases cylinder Body, resisting medium flow through the damping structure on piston, enter the room B from the room A, and resisting medium passes through piston and pedestal two when reset The damping structure of a position generates Double damping effect, controls the reset speed of buffer.
When the opening of damping structure is larger, damping is smaller, and reset speed is very fast;When the opening of damping structure is smaller, resistance Buddhist nun is larger, and reset speed is slower.
