Abstract
The invention discloses an overload prevention hydraulic balance absorber. The overload prevention hydraulic balance absorber comprises a main cylinder, an auxiliary cylinder arranged inside the main cylinder, a main anti-shock device, an auxiliary anti-shock device and at least two overload prevention devices, wherein the overload prevention devices are symmetrically, evenly and fixedly arranged on the outer side of the main cylinder. The overload prevention hydraulic balance absorber aims at achieving the technical purpose of avoiding the occurrence that when an automobile with the absorber is driven on a rugged road section, the absorber is damaged due to overload. By means of the overload prevention hydraulic balance absorber, the shock explosion characteristic of kazoe in a shock bag in each overload prevention device is utilized, so that when the absorber is shocked by overload, the kazoe is shocked to release gas to buffer the overload pressure shock, the occurrence that the absorber is shocked by the overload or even damaged is avoided, the safety of the absorber is protected, the probability of damage of the absorber is reduced, the using safety of the absorber is improved, and the service life of the absorber is prolonged.
Description
Technical field
The present invention relates to a kind of vapour vehicular shock absorber, particularly a kind of antioverloading hydro-cushion vibration damper.
Background technique
Vibration damper (Absorber), 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 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.On piston, have throttle orifice, the oil in two-part space that makes to be separated by piston can 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 throttle orifice size is constant, when 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 throttle orifice aperture becomes, and damping diminishes.Because piston is bidirectional-movement, so leaf spring valve is all housed in the both sides of piston, 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 exchange to maintain balance oily in inner core with urceolus.So will have four valves 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 when vehicle is 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.
Summary of the invention
For addressing the above problem; antioverloading hydro-cushion vibration damper disclosed by the invention; utilize the shock outburst character of clashing into kazoe in bag; when vibration damper is subject to overload impact, kazoe is subject to impacting and discharges gas, and then overload pressure is impacted and cushioned; protected the safety of vibration damper; reduce the possibility that vibration damper damages, improved the Security that vibration damper uses, extended the working life of vibration damper.
