Abstract
The utility model discloses an automobile shock absorber. The automobile shock absorber comprises a cylinder body, wherein a piston is arranged in the cylinder body; a piston rod is arranged on the piston and extends out of the cylinder body; a spring is further sleeved on the cylinder body; the two axial ends of the spring are respectively a free end and a fixed end; the free end is connected with the piston rod, and the fixed end is connected with the cylinder body; the cylinder body consists of an upper cylinder body and a lower cylinder body which are cylindrical; internal threads are formed on the inner wall of the cylindrical opening of the upper cylinder body, and external threads are formed on the outer wall of the cylindrical opening of the lower cylinder body and matched with the internal threads of the upper cylinder body; a cylindrical opening cover of the upper cylinder body is arranged at the cylindrical opening of the lower cylinder body and forms a closed oil storage space; and the cylinder depth of the upper cylinder body is 20-50mm. The upper cylinder body and the lower cylinder body can be rotated relative to each other, so that the whole length of the cylinder body can be adjusted, and accordingly, the oil storage space in the cylinder body can also be correspondingly changed, so that the hardness of the shock absorber is changed. The cylinder depth of the upper cylinder body is 20-50mm and preferably 30mm according to practical applications; and the overlength cylinder depth can easily cause insufficient rigidity of upper cylinder body, however, a required adjustment effect cannot be achieved if the upper cylinder body is too short, and on the contrary, the production cost is increased.
Description
Technical field
The utility model relates to a kind of vibration damper, especially a kind of automobile vibration damper.
Background technique
Vibration damper is an important component part of automobile suspension system, the concussion when it is mainly used to suppress bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, though the 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 big resistance too firmly, hinders the spring proper functioning.In the retrofit process about suspension system, hard vibration damper will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight, and therefore heavier car generally adopts harder vibration damper.
At present, the conventional vibration damper structure that occurs on the market number is disclosed among the CN201241935Y " vibration damper " as the Chinese patent notice of authorization mostly, the hardness of this traditional shock absorber, outside the Pass having with spring, also relevant with the size of oil storage space in the cylinder body.According to the difference of vehicle, it all is well-determined that traditional shock absorber is produced its specification of back, also be that the oil storage space in the cylinder body is well-determined, and this structure has limited the application area of vibration damper virtually, thereby has been unfavorable for the mutual unification between different automobile types.In addition, same vehicle at last just, according to the difference of road conditions, vibration damper often needs to debug accordingly, and the debugging of traditional vibration damper often concentrates on spring and adjusts, and makes that the mode of its debugging is too poor, is unfavorable for the application in complicated place.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of can change oil storage space in the cylinder body, and safe automobile vibration damper simple to operate.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of automobile vibration damper, comprise cylinder body, be provided with piston in the cylinder body, piston is provided with and extends to the outer piston rod of cylinder body, also be arranged with spring on the cylinder body, the axial two ends of spring are respectively free end and fixed end, this free end is connected with piston rod, fixed end is connected with cylinder body, described cylinder body is made up of upper cylinder body and lower cylinder body, upper cylinder body and lower cylinder body are tubular, the inwall of upper cylinder body tube port position is provided with internal thread, the outer wall of lower cylinder body tube port position is provided with the outside thread suitable with the upper cylinder body internal thread, and the upper cylinder body nozzle covers at the lower cylinder body tube port position and forms the oil storage space of sealing, and the tube of upper cylinder body is dark to be 20 ~ 50mm.
Preferably be set to: the dark 30mm of being of the tube of described upper cylinder body.
Further be set to: described piston rod runs through lower cylinder body and extends to outside the lower cylinder body, and the end away from lower cylinder body on the upper cylinder body is provided with installing ring.
Further be set to: the inner ring of described installing ring is provided with rubber pad.
Further be set to: also comprise spring seat, spring seat be provided with lower cylinder body on the suitable screw of outside thread, spring fixed end press on the spring seat by elastic force.
Further be set to: also include locking nut, outside thread is suitable and be used for the locking spring seat on locking nut and the lower cylinder body again.
The beneficial effects of the utility model are: the nozzle of upper cylinder body and lower cylinder body docks and forms the oil storage space of sealing mutually, since between upper cylinder body and lower cylinder body by the cooperation that is threaded, so by relatively rotating between upper cylinder body and lower cylinder body, just can realize the adjustment of cylinder body entire length, and relatively, relative variation also takes place in the oil storage space in the cylinder body, so when piston is started working, along with the variation of oil storage space size, corresponding change also will take place in the hardness of vibration damper.According to practical application, the tube of upper cylinder body is dark to be 20 ~ 50mm, is preferably 30mm, and the long rigidity of cylinder that causes easily is not enough, and too weak point does not then reach the effect that will regulate, has increased cost of production on the contrary.Fixed installation between upper cylinder body and vehicle frame can be convenient to by installing ring, and noise in the using process can be reduced by rubber pad.In addition, by the rotation spring seat, can realize spring seat along the axial movement of lower cylinder body, thereby realize the adjusting to the spring initial length, as for locking nut, can further fix spring seat, the stability of spring when improving work.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, present embodiment comprises cylinder body 1, is provided with piston 2 in the cylinder body 1, piston 2 is provided with the piston rod 3 that extends to outside the cylinder body 1, also is arranged with spring 4 on the cylinder body 1, and the axial two ends of spring 4 are respectively free end and fixed end, this free end is connected with piston rod 3, and fixed end is connected with cylinder body 1.Wherein, cylinder body 1 is made up of upper cylinder body 11 and lower cylinder body 12, upper cylinder body 11 and lower cylinder body 12 are tubular, the inwall of upper cylinder body 11 tube port positions is provided with internal thread, the outer wall of lower cylinder body 12 tube port positions is provided with the outside thread suitable with upper cylinder body 11 internal threads, upper cylinder body 11 nozzles cover at lower cylinder body 12 tube port positions and form the oil storage space 13 of sealing, and the tube of upper cylinder body 11 is dark to be 30mm.According to actual needs, dark can between 20 ~ 50mm, the adjustment of tube of upper cylinder body 11, and also this scope falls in the protection domain of the present utility model.
