Description
Technical field
The utility model relates to dampening arrangement field, particularly, relates to a kind of vibration damper for automobile.
Background technique
along with the development of technology, the type of automobile absorber have also been obtained very large expansion.In order to the piston lever of reducer solving double-barrel structure is moving up and down in process, if the cut having harder dust granule to cause piston rod in rod seal place, cause the problems such as the leakage of high pressure sealing gas, underpressure, adopt existing monotubular structure.Existing vibration damper, it comprises cylinder body, piston rod, fixing main piston on the piston rod and sub-piston, buffering ball between main piston and sub-piston, piston rod is moving up and down in process, and main piston and sub-piston can collide the end face of cylinder body, and namely cylinder body end face easily goes wrong.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of vibration damper, its structural stability, and little to the impact force of cylinder body end face during use, cylinder body is not easily destroyed.
The technical scheme in the invention for solving the above technical problem is:
A kind of vibration damper, comprise the cylinder body of band piston rod, cylinder body is provided with oil hole, be positioned at main piston and the sub-piston of cylinder body, described main piston and sub-piston are provided with oil leak hole, described main piston is fixed on piston rod one end, the two ends of described cylinder body are provided with damping device, described damping device and piston rod joint are provided with a circle waterproof ring, the inwall of described cylinder body is at least provided with a circle groove, the width of described groove notch is less than the thickness of sub-piston and main piston, described sub-piston is connected on main piston by least two springs, buffering ball is provided with between described main piston and sub-piston.
The principle that the utility model realizes damping is substantially identical with prior art.The utility model improves on the basis of existing technology, one, all arranges damping device at the two ends of cylinder body, utilizes damping device to alleviate main piston and sub-piston to the impact force of cylinder body end face, namely alleviates the destruction to cylinder body end face; Its two, sub-piston is connected on main piston by spring, to reduce main piston and sub-piston in moving process to the striking force of cylinder body upper and lower end face; Its three, damping device and piston rod joint are provided with a circle waterproof ring, utilize waterproof ring to strengthen the waterproof ability of cylinder body, avoid oil in cylinder to leak in piston rod moving process; Its four, the inwall of cylinder body arranges groove, utilizes the sidewall of the oil in groove to main piston and sub-piston to lubricate, be convenient to moving up and down of main piston and reviving-match.Originally spring is in plateau, piston rod is when moving down, spring is compressed, namely there is downward active force to sub-piston, namely drive sub-piston to move down and collide on damping device, and during collision, main piston also can continue mobile downwards, its piston rod power acted on main piston is greater than sub-piston and acts on power on damping device, namely extends the time that sub-piston acts on the collision of cylinder body, but reduces the size of striking force; When piston rod moves up, because the pulling force of spring to sub-piston makes sub-piston move up, because spring has downward pulling force to main piston, the active force making main piston strike cylinder body end face reduces; Namely the striking force to cylinder body is reduced.Because spring is to a fixing only point of sub-piston, when moving up and down, when power is excessive, the fixation of spring is not strong, utilizes at least two springs to be fixed sub-piston, strengthens the fixing stability of sub-piston.When main piston and sub-piston are when moving up and down, move to the position of groove, oil is injected with in groove, the sidewall of oil in groove to main piston and sub-piston lubricates, width due to groove notch is less than the thickness of sub-piston and main piston, sub-piston and main piston can not be snapped in groove, namely strengthen the smoothness that sub-piston and main piston move up and down.
As preferably, described groove has a circle.
Further, described groove is positioned at the middle part of cylinder body.
As preferably, described damping device comprises isolation net and the damping device between isolation net and cylinder body end face.
Further, described damping device is elastic ball.
As preferably, described waterproof ring is rubber ring, and described rubber ring is wrapped in the surrounding of piston rod.
To sum up, the beneficial effects of the utility model are:
1, the utility model arranges damping device on the end face of cylinder body, and it plays the impact force of main piston and sub-piston and slows down effect, protects, avoid end face to be damaged to cylinder body end face.
2, sub-piston of the present utility model is connected on main piston by spring; make the motion of main piston and sub-piston asynchronous; and the active force of spring can alleviate main piston and sub-piston to the impact force of cylinder body end face, protects, avoid end face to be damaged to cylinder body end face.
3, the utility model is provided with a circle waterproof ring at damping device and piston rod joint, utilizes waterproof ring to strengthen the waterproof ability of cylinder body, avoids oil in cylinder to leak in piston rod moving process.
4, the utility model utilizes many springs to be fixed sub-piston, strengthens the stability that sub-piston is fixing.
5, the utility model is arranging groove on the inwall of cylinder body, utilizes the sidewall of the oil in groove to main piston and sub-piston to lubricate, and is convenient to moving up and down of main piston and reviving-match.
