Buffer-oriented part for vibration damper of the present utility model, comprises the guide sleeve in the middle part of the piston rod for being enclosed within vibration damper; Guide sleeve generally adopts the material softer than spring material, such as plastics or nylon etc., avoids spring works process to rub with piston rod by bending producing the wearing and tearing that abnormal sound affects performance or causes piston rod and spring, makes whole working procedure more smooth and easy.
Further, also comprise at least axial outwards spacing hydraulic cushion part being arranged at piston rod, the setting position of hydraulic cushion part makes the piston of piston assembly prevent at the bottom of rigid touch at end of travel; Working stroke end refers to the final stroke of piston at damping cylinder least significant end and spring-compressed, at working stroke tip designs hydraulic damping buffer structure, the gradual increase of compression damping power can be made, there will not be the undesirable conditions such as the stiff tactile end when ensureing forward stroke limit situation, ensure that travelling comfort, working procedure more safety and stability is reliable.
Further, guide sleeve is that plastics or nylon are made; Cost is lower and easily make, and have good convertibility, meanwhile, plastics or nylon have certain hardness and toughness, has certain self-lubricating function, alleviate friction damage for collision.
Further, guide sleeve is longitudinally the little structure in two broad in the middle; Be adapted to the distortion of spring, smooth contact occurs during use, reduce further to impact.
Further, guide sleeve is at circumferencial direction and column distribution arranges cannelure; This cannelure makes the cross section of guide sleeve be the tooth-shape structure of spline type structure or smooth excessiveness; guide sleeve is made to save finished material; reduce rubbing contact area; guide sleeve cylindrical is made to reduce hardness and impact force; first soft rear order just during impact; to the distortion collision of spring, there is effective buffering; simultaneously; there is good guide effect; be beneficial to and protect guide sleeve not occur to wear and tear faster, clash into lose efficacy and effectively led and avoid the bending rear hydraulic performance decline of damping spring, be beneficial to and keep good damping precision.
Further, hydraulic cushion part is cushion collar structure, and this cushion collar structure is to the diminishing taper of end face near the end of damping cylinder; When carrying out slowly before piston touches the end, the little end surface first contact damping cylinder end cap of taper, is formed by the contact of the little reaction force increased gradually, ensures cushioning effect, and raising vibration damper touches the travelling comfort at the end.
Further, hydraulic cushion part is coated at an inner sleeve, and described inner sleeve is T-shaped cover, and the catch of the major part that hydraulic cushion part is overlapped by this T-shaped and T-shaped cover cylindrical realizes axial limiting on interior cover; Carry out in buffering course, make buffering course be divided into hydraulic cushion part and T-shaped cover two-stage, increase cushioning effect; Certainly, T-shaped cover major part in the one end being away from damping cylinder, to form the buffer stop to hydraulic cushion part.
Further, described cannelure makes the cross section of guide sleeve form the tooth type structures of tooth top and the equal rounding off of tooth root, generally adopts arc transition, is easy to processing; Be beneficial to reduction stress to concentrate, there is when camber of spring clashes into the opposing of higher toughness, meanwhile, also comparatively submissive to the reaction force of spring, avoid concentrating effect.
Further, described hydraulic cushion part is coaxially arranged at the end of guide sleeve, and guide sleeve has certain support effect to hydraulic cushion part.
Further, the length of described guide sleeve is more than or equal to 1/3rd of piston rod, is easy to form the general protection to piston rod, spring, avoids contact and has enough buffer lengths.
The beneficial effects of the utility model: the buffer-oriented part for vibration damper of the present utility model; adopt the structure of guide sleeve; the middle part of piston rod is arranged on during use; and in the middle part of this just spring be easy to the position of the distortion departing from center line; the collision between spring and piston rod and friction can be avoided during use, be beneficial to protection piston rod and spring, ensure the smoothness of relative movement therebetween; reduce shock absorber noise, improve travelling comfort and stationarity.
