Description
Technical field
The present invention relates to dampening arrangement field, particularly, relate to a kind of structural stability type automobile absorber.
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.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automobile absorber, its structural stability, and little to the impact force of cylinder body end face during use, cylinder body is not easily destroyed.
The present invention's adopted technological scheme that solves the problem is:
A kind of structural stability type automobile absorber, comprise the cylinder body of band piston rod, the main piston being positioned at cylinder body and sub-piston, described main piston and sub-piston are provided with oil leak hole, described main piston is fixed on piston rod one end, described cylinder body is provided with oil hole, 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, described sub-piston is connected on main piston by least two springs, is provided with buffering ball between described main piston and sub-piston.
The principle that the present invention realizes damping is substantially identical with prior art.The present invention 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.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.
As preferably, described piston rod is provided with retaining ring.
As preferably, described damping device comprises isolation net and the damping device between isolation net and cylinder body end face.Isolation net plays fixation to elastic ball, and can alleviate main piston and sub-piston to the striking force of cylinder body end face.
Further, described damping device is elastic ball.
As preferably, described waterproof ring is rubber ring.
As preferably, described spring has two, and diametrically same and equidistant with the center of circle at sub-piston respectively.
To sum up, the invention has the beneficial effects as follows:
1, the present invention 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 invention is connected on main piston by spring, makes 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 present invention 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 present invention utilizes many springs to be fixed sub-piston, strengthens the stability that sub-piston is fixing.
