Abstract
The utility model discloses a shock absorber which comprises a piston rod, a spring disk and an oil storage barrel assembly, wherein the oil storage barrel assembly comprises an oil storage barrel and a working cylinder arranged in the oil storage barrel; the top of the oil storage barrel is the seal of the shock absorber; the piston rod is arranged in the working cylinder; the piston rod and the oil storage barrel are coaxially arranged; the spring disk is sheathed in the middle of the oil storage barrel; the diameter of the fixedly matching position of the oil storage barrel and the spring disk is matched with the inner diameter of the spring disk; and the oil storage cylinder and the spring disk are fixedly matched in a welding mode. The spring disk of the shock absorber is installed out of the oil storage cylinder in a welding mode, thus the spring disk and the oil storage cylinder are integrated into one body, tensile strength is higher, and the spring disk can be prevented from shifting or breaking to fall when the shock absorber works. The product is more stable to use, the durability is improved, and the service life is prolonged.
Description
Technical field
The utility model relates to the auto parts machinery field, is specifically related to the vibration damper under a kind of vehicle chassis.
Background technique
Vibration damper is an important accessory of automobile, the concussion when vehicle shock absorber 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 vehicle shock absorber is used for suppressing this spring jump.
The vibration damper main structure has spring holder, piston rod, clutch release slave cylinder, piston, oil storage cylinder, guider, dust-proof cover and oil sealing, and guider is arranged between piston rod and the oil storage cylinder, and with the clutch release slave cylinder interference fit, with the oil storage cylinder Spielpassung.Spring holder is arranged on the middle part of oil storage cylinder, in be provided with spring.Vibration damper of the prior art is produced in the mode of the bag that rises, and spring holder is press-fited the spring holder interference is arranged on outside the oil storage cylinder again, carries out spraying binder at last again.When vehicle driving, jolting of vehicle body can make the spring in this class spring plate of shock absorber stretch and twisting thereupon, like this, being arranged on the outer spring holder of oil storage cylinder may be at the oil storage cylinder superior displacement, influence the damping, buffering effect of vibration damper, even spring holder can make defective shock absorber from cracked coming off on the oil-storing barrel.
Summary of the invention
The purpose of this utility model: in order to overcome the deficiencies in the prior art, the utility model provides a kind of durability height, the vibration damper of long service life.
The technical solution of the utility model: a kind of vibration damper, comprise piston rod, spring holder, oil storage cylinder assembly, described oil storage cylinder assembly comprises oil storage cylinder and is arranged on the interior clutch release slave cylinder of oil storage cylinder, the oil storage cylinder top is sealing of vibration damper, piston rod is arranged in the clutch release slave cylinder, piston rod and the coaxial setting of oil storage cylinder, described spring holder is set in the oil storage cylinder middle part, oil storage cylinder cooperates with the internal diameter of spring holder with the diameter at spring holder secure fit place, and oil storage cylinder and spring holder are by the mode secure fit of welding.
Further setting of the present utility model: described oil storage cylinder assembly also comprises the bottom that is arranged on the oil storage cylinder bottom, and described bottom is provided with suspension ring.Adopt above-mentioned further be provided with after, make the installation of the bottom of vibration damper of the present utility model and automobile chassis more stable.
Further setting of the present utility model: be provided with suspension ring rubber between described bottom and the suspension ring.
Further setting of the present utility model: the sealing part of described vibration damper is provided with dust cover, the setting that is sealed and matched of dust cover and oil storage cylinder.Adopt above-mentioned further be provided with after, prevent that more effectively dust from entering oil storage cylinder inside.
Further setting of the present utility model: the part that described piston rod stretches out oil storage cylinder is provided with limit stoper.Adopt above-mentioned further be provided with after, moving displacement that can the limited piston bar is avoided the bottom of the excessively flexible destruction work cylinder of piston rod.
Further setting of the present utility model: described limit stoper is the upper limit packing ring.
The spring holder of vibration damper of the present utility model is installed in outside the oil storage cylinder in the mode of welding, make spring holder and oil storage cylinder form one, tensile strength is higher, avoid spring holder when vibration damper is worked, to be shifted or cracked coming off, it is more stable that this product is used, improve durability, prolonged working life.
