Description
Technical field
The utility model relates to a kind of damping, buffering equipment, particularly a kind of straight cylinder type vibration damper that is applicable to 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.
Summary of the invention
For addressing the above problem; The disclosed straight cylinder type vibration damper of the utility model; Through the damping rubber cushion that the auxiliary fixing that is provided with on the cylinder body and auxiliary damping are used, improved the damping performance and the buffering ability of vibration damper effectively, thereby improved the Security of vibration damper; Prolong the continuous working life of vibration damper, thereby reduce the O&M cost of vibration damper effectively.
The disclosed straight cylinder type vibration damper of the utility model; Comprise pressure-limit valve and loam cake that cylinder body, the connecting rod with the coaxial setting of cylinder body, the piston that is set to the connecting rod bottom, Sealing, the wide-mouth be made up of inner core and urceolus do not have the cup-shaped fastener in the end, are arranged on the urceolus inner bottom part and connect with the inner core lower ends; One end of fastener has affixed edge; The axis place of Sealing and loam cake is provided with through hole, and Sealing is arranged on the urceolus inside top and is connected with the open-topped of inner core, and loam cake is fixedly connected on the urceolus upper end; Connecting rod passes coaxial being set in the inner core of through hole of loam cake and Sealing, and fastener is fixedly installed on the urceolus.
A kind of improvement of the disclosed straight cylinder type vibration damper of the utility model, the fastener that is arranged on the urceolus is provided with 1 at least.
Another of the disclosed straight cylinder type vibration damper of the utility model improved, and fastener is arranged on the upper end of urceolus, and affixed edge is in the position that is directed downwards along the outside tube bottom of urceolus axis.
Another improvement of the disclosed straight cylinder type vibration damper of the utility model, the straight cylinder type vibration damper also comprises the damping rubber cushion, described damping rubber cushion is arranged between fastener and the urceolus.
The disclosed straight cylinder type vibration damper of the utility model, simple in structure, install and fix conveniently; Installation environment and fixed component are not had special requirement, be utilized at least one fastener of urceolus arranged outside simultaneously, improved the vibration damper mounting stability effectively; Security and shock resistance that equipment operation uses have been improved; Reduce the possibility that bumps and damage owing to installation is not firm in using, thereby prolonged the working life of equipment effectively, between fastener and urceolus, added the damping rubber cushion in addition; Improved release and the buffering ability of vibration damper effectively to vibrations; Thereby improved the damping performance of vibration damper effectively, and then improved the continuous operations and continuous working life of vibration damper, improved the efficient of production and transport.
