The anti-overloading hydraulic balance shock absorber enables kazoe to be shocked to release gas when being shocked by overload by utilizing shock explosion property of the kazoe in a shock bag in an anti-overloading device, further buffers overloading pressure shock, protects the situations that the shock absorber is shocked by the overload and even has loss from happening, protects safety, reduces damage possibility, improves use safety, and prolongs service life.
Description
Technical field
The utility model relates to a kind of automobile vibration damper, particularly a kind of antioverloading hydro-cushion vibration damper.
Background technique
Vibration damper (Absorber), concussion when vibration damper 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, although 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 large resistance too firmly, hinders the spring normal operation.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, therefore the harder vibration damper of the general employing of heavier car.With draw the device that joins of shake bent axle, the torsional shaking of the bent axle that is used for contending with (be the impact force of bent axle subject cylinder igniting and the phenomenon that twists).
The structure of vibration damper is in the piston rod insertion cylinder with piston, is full of oil in cylinder.Throttle orifice is arranged on piston, make the oil in two-part space separated by piston to complement each other.Damping produces during by throttle orifice at the sticking oil of tool, and throttle orifice is less, and damping force is larger, and the viscosity of oil is larger, and damping force is larger.If the throttle orifice size is constant, when the vibration damper operating rate is fast, the absorption that conference affects impact is crossed in damping.Therefore, a discoid leaf spring valve is set in the outlet port of throttle orifice, when pressure becomes large, valve is backed down, and it is large that the throttle orifice aperture becomes, and damping diminishes.Because piston is bidirectional-movement, so in the both sides of piston, the leaf spring valve all is housed, be called respectively compression valve and rebound valve.
Vibration damper can be divided into double barreled and single-cylinder type by its structure.Double barreled refers to that vibration damper has inside and outside two cylinders, and piston moves in inner core, and due to the entering and extracting out of piston rod, in inner core, the volume of oil increases and contraction thereupon, therefore will be by with urceolus, exchange to maintain balance oily in inner core.So four valves will be arranged in dual-tube shock absorber,, two throttle valve on piston above-mentioned, be contained in addition the flowing valve that completes exchange interaction and recuperation valve between inner/outer tube.The car body quality of automobile is all larger, inertia in the process of moving too very for protruding, the travelling comfort of driving in order to improve taking advantage of of vehicle, it is particularly important that vibration damper seems therein.Particularly work as vehicle under being fully loaded with, while running into comparatively rugged road, for example emergent zanjon or breach, be a very large test to vibration damper to a large extent, even under serious state, meeting cause damage to vibration damper itself, thereby affects the rideability of vehicle.
