Background technique
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.Its working principle is that while there is relative movement when vibrations between vehicle frame or vehicle body and vehicle bridge, the piston in vibration damper moves up and down, and the fluid in vibration damper chamber just flows in another chamber through different holes from a chamber repeatedly.The now intermolecular interior friction of the friction between hole wall and fluid and fluid forms damping force to vibrations, and making thump Conversion of Energy is fluid heat energy, then is absorbed and be dispersed in atmosphere by vibration damper.
Existing vibration damper generally comprises vibration damper housing, in housing, be provided with oil pocket, in oil pocket, be provided with piston and piston rod, at housing, be arranged with damping spring outward, the two ends, one end of damping spring are provided with installs the spring seat that damping spring is used, existing spring seat general position is non-adjustable, and the precompression of damping spring can not regulate, and can not adapt to various road conditions.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the utility model provides a kind of fixedly damping spring and can carry out coarse adjustment and fine setting, the vibration damper with spring mounting seat that adaptability is stronger to the precompression of damping spring.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of vibration damper with spring mounting seat, comprise housing, in described housing, be provided with oil pocket, in described oil pocket, be provided with piston and piston rod, one end of described piston rod passes housing, form piston rod extension part, described piston rod extension part is provided with coupling hook, described housing is arranged with damping spring outward, described housing is provided with the first spring seat outward, described coupling hook is provided with the second spring seat, the setting that offsets of one end of described damping spring and the first spring seat, described damping spring is away from the setting that offsets of one end of the first spring seat and the second spring seat, the second described spring seat comprises the second spring lamellar body, the second described spring lamellar body is annular slice, the second described spring lamellar body week is along being provided with the second flange extending towards coupling hook, the second described flange is connected a side week of placement along being provided with the second spring butt sheet with the second spring lamellar body away from it, described damping spring offsets away from one end of the first spring seat and the second described spring butt sheet.
As preferably, described coupling hook comprises connecting head and is connected inserted sheet, described connecting head middle part is provided with attachment hole, described piston rod extension part penetrates in described attachment hole away from one end of piston, on the outer side wall of described connecting head, be connected with auxiliary fixed plate, described auxiliary fixed plate is away from the setting that offsets of one end of itself and connecting head joint and described the second spring seat.Adopt after above-mentioned preferred version, connecting head is more firm with being connected of piston rod extension part, and auxiliary fixed plate can play auxiliary fixation to the second spring seat simultaneously, avoids the second spring seat to be damaged under the pressure of damping spring.
As preferably, the second described spring seat is provided with cushion pad by a side of damping spring.Adopt after above-mentioned preferred version, adopt after above-mentioned preferred version, can avoid the direct collision of the second spring seat and housing, effectively protect the second spring seat and housing.
As preferably, described piston rod passes housing place and is provided with lid.Adopt after above-mentioned preferred version, can avoid entering of extraneous dust, play the effect of dustproof and waterproof.
As preferably, between described lid and piston, be provided with damping device, described damping device comprises damping spring and elastomer, described damping spring and elastomer are set in outside piston rod by piston to lid direction successively, one end and the piston of described damping spring offset, the setting that offsets of the other end and described elastomer.Adopt after above-mentioned preferred version, can avoid the destruction of internal piston piston to lid etc.
Vibration damper with adjustable spring fitting seat of the present utility model can be by the first spring seat to carrying out coarse adjustment in the precompressed of damping spring, during adjusting, by adjustment, regulate the position of the second spring seat, and the second spring seat is provided with the second flange and the second spring butt sheet can slightly be out of shape under the pressure-acting of damping spring, thereby the precompression of damping spring is finely tuned.
