Description
Technical field
The utility model relates to a kind of damping, buffering equipment, particularly is applicable to a kind of straight cylinder type vibration damper with draw-in groove that automobile shock is used.
Background technique
Concussion when vibration damper (Absorber), vibration damper mainly are used for suppressing 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 with hard spring mutually, and the hardness of spring is closely bound up with car weight, the harder vibration damper of the general employing of therefore 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 that the piston rod that has piston inserts in the tube, in tube, is full of oil.Throttle orifice is arranged on the piston, make that the oil in two-part space that is separated by piston can complement each other.Damping produces during through throttle orifice at the oil with viscosity, and throttle orifice is more little, and damping force is big more, and the viscosity of oil is big more, and damping force is big more.If the throttle orifice size is constant, when the vibration damper operating rate was fast, the absorption of affects impact was crossed in damping.Therefore, in the outlet port of throttle orifice a discoid leaf spring valve is set, when pressure became big, valve was backed down, and it is big that the throttle orifice aperture becomes, and damping diminishes.Because piston is a bidirectional-movement, so in the both sides of piston the leaf spring valve is housed all, is called compression valve and rebound valve respectively.
Vibration damper can be divided into double barreled and monotubular formula by its structure.Double barreled is meant that vibration damper has inside and outside two tubes, and piston moves in inner core, because the entering and the extraction of piston rod, the volume of oil increases and contraction thereupon in the inner core, therefore will be through exchanging the balance of keeping oil in the inner core with urceolus.So four valves will be arranged in the dual-tube shock absorber, promptly two throttle valve on piston above-mentioned, be contained in the flowing valve and the recuperation valve of the completion exchange interaction between the inner/outer tube in addition.So just require vibration damper in use can be in dynamically balanced state well; Because the quality of vibration damper is big; Connector element is complicated, and performance requirement is strict, all often has complicated structure characteristic usually and annexation is installed; What require also simultaneously that installing and using of vibration damper can be enough is firm, to improve the Security of driving transportation.
