Description
Technical field
The utility model relates to dampening arrangement field, particularly, relates to a kind of 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.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of automobile absorber, 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 automobile absorber, comprise the cylinder body of band piston rod, the main piston being positioned at cylinder body and sub-piston, described main piston is fixed on piston rod one end, described main piston and sub-piston are provided with oil leak hole, the two ends of described cylinder body are provided with damping device, described sub-piston is connected on main piston by spring, is provided with buffering ball between described main piston and sub-piston, and described cylinder body is provided with oil hole.
The principle that the utility model realizes damping is substantially identical with prior art.The utility model has done 2 improvement on the basis of existing technology, and 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 the upper and lower end face of cylinder body.Originally spring is in plateau, piston rod is when moving down, spring is compressed, namely downward active force is had to sub-piston, namely driving sub-piston to move down collides 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; 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.
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.
Isolation net plays fixation to elastic ball, and can alleviate main piston and sub-piston to the striking force of cylinder body end face.
As preferably, described oil hole is positioned on the sidewall of cylinder body.Oil hole arranges on a side wall of the cylinder by the utility model, is namely convenient to oiling in cylinder body.Existing oil hole is arranged on the end face of cylinder body, and the utility model is provided with damping device on end face, if do not improve the position of oil hole, is then not easy to oiling.
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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark and corresponding component title in accompanying drawing: 1, cylinder body; 11, piston rod; 12, oil hole; 2, main piston; 3, sub-piston; 4, spring; 5, buffering ball; 6, isolation net; 7, damping device; 8, oil leak hole.
Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the utility model do, but mode of execution of the present utility model is not limited thereto.
Embodiment 1:
A kind of automobile absorber as shown in Figure 1, comprise the cylinder body 1 of band piston rod 11, the main piston 2 being positioned at cylinder body 1 and sub-piston 3, described main piston 2 is fixed on piston rod 11 one end, described main piston 2 and sub-piston 3 are provided with oil leak hole 8, the two ends of described cylinder body 1 are provided with damping device, described sub-piston 3 is connected on main piston 2 by spring 4, is provided with buffering ball 5 between described main piston 2 and sub-piston 3, and described cylinder body 1 is provided with oil hole 12.Other structures of the present embodiment are identical with structure of the prior art.The principle that the present embodiment realizes damping is same as the prior art.The present embodiment has done 2 improvement on the basis of existing technology, and 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 the upper and lower end face of cylinder body.Originally spring is in plateau, piston rod is when moving down, spring is compressed, namely downward active force is had to sub-piston, namely driving sub-piston to move down collides 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; 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.
Embodiment 2:
A kind of automobile absorber as shown in Figure 1, the present embodiment is optimized on the basis of above-described embodiment, and namely described damping device comprises isolation net 6 and the damping device 7 between isolation net 6 and cylinder body 1 end face.
