Description
Technical field
The utility model relates to automotive field, relates in particular to a kind of adjustable automobile vibration damper.
Background technique
Along with reform and opening-up deepens continuously and develops, improving constantly of growth of the national economic rate, is developed rapidly commodity, trade and traffic etc., therefore, on the one hand, has promoted automobile industry fast-developing; On the other hand, due to the raising of people's living standard, in continuous increase, more and more higher to the quality requirement of car to the demand of automobile, not only require the host performance of car good, and require higher to its auxiliary system.Automobile absorber is exactly the key element of auxiliary system.
Concussion when vibration damper is mainly used to suppress rebound after spring shock-absorbing and from the impact on road surface.When through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper is too soft, and vehicle body will jump up and down, and vibration damper will bring too large resistance too firmly, hinders spring normally to work.When automobile car weight is different with road conditions, need to adjust the hardness of automobile absorber, the hardness of vibration damper regulates normally by the spring at vibration damper outer cover different size, therefore on automobile, conventionally need to be equipped with the spring that plurality of specifications is different, so the cost that has increased vehicle maintenance and debugging, has reduced debugging efficiency.
Model utility content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and the adjustable automobile vibration damper that a kind of hardness debugging cost is low, efficiency is high is provided.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of adjustable automobile vibration damper, comprise cylinder body, in cylinder body, be provided with piston, piston is provided with the piston rod extending to outside cylinder body, cylinder body outer cover is provided with spring, the axial two ends of spring are respectively spring free end and spring fixed end, described spring fixed end is connected with described cylinder body, upper cover of piston rod in described cylinder body outside is provided with the controlling mechanism of capable of regulating vibration damper hardness, the center of described controlling mechanism is provided with the piston rod hole coordinating with piston rod, spring free end is connected on described controlling mechanism, described controlling mechanism is flexibly connected with described piston rod by described piston rod hole.
Further, described controlling mechanism comprises screw mandrel, adjusting nut and blade, and described blade is movably located on described screw mandrel, and described spring free end is connected on described blade, and described piston rod is flexibly connected with described screw mandrel.
Further, between described piston rod and described screw mandrel for removably connecting.
Further, described piston rod internal surface of hole is provided with dust-proof seal ring.
Compared with prior art, the utility model has the advantage of: automobile absorber of the present utility model, by at the outside sheathed controlling mechanism of piston rod, in order to the initial length of Regulation spring, realize the hardness debugging to vibration damper, do not need to change spring, reduce debugging cost, increased debugging efficiency.

Embodiment
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
In conjunction with Fig. 1, Fig. 2 shows a kind of embodiment of the utility model adjustable automobile vibration damper, this adjustable automobile vibration damper, comprise cylinder body 1, in cylinder body 1, be provided with piston 2, piston 2 is provided with the piston rod 3 extending to outside cylinder body 1, cylinder body 1 outer cover is provided with spring 4, the axial two ends of spring 4 are respectively spring free end 41 and spring fixed end 42, spring fixed end 42 is connected with cylinder body 1, on the piston rod 3 of cylinder body 1 outside, be arranged with the controlling mechanism 5 of capable of regulating vibration damper hardness, the center of controlling mechanism 5 is provided with the piston rod hole 51 coordinating with piston rod 3, spring free end 41 is connected on controlling mechanism 5, controlling mechanism 5 is flexibly connected with piston rod 3 by piston rod hole 51.
Controlling mechanism 5 comprises screw mandrel 52, adjusting nut 53 and blade 54, blade 54 is movably located on screw mandrel 52, spring free end 41 is connected on blade 54, piston rod 3 is flexibly connected with screw mandrel 52, use adjusting nut 53 rotary screw rods 52, can make blade 54 move axially along screw mandrel 52, thereby stretch or Compress Spring 4, the elastic strength of Regulation spring 4, reaches the object that regulates vibration damper hardness.
In the present embodiment, between piston rod 3 and screw mandrel 52, for removably connecting, can change according to car weight and road conditions the position of controlling mechanism.
In the present embodiment, piston rod hole 51 internal surfaces are provided with dust-proof seal ring 55, thereby can avoid dust to enter the friction increasing between piston rod 3 and controlling mechanism 5, cause blade 54 motions dumb.
Although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model.Any those of ordinary skill in the art, in the situation that not departing from technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solutions of the utility model,, all should drop in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to the utility model technical spirit.
