Description
Technical field
The utility model relates to a kind of damper parts, particularly the damping dress of the anti-rigidity contact of a kind of damperPut.
Background technology
Damper is the necessary parts of motor vehicles, handling, the comfortableness of structure influence car load, performanceWhether reliable and stable, be directly connected to the safe and reliable of car load, comfortableness and handling. Existing damper is generalAdopt fixing structure and fixing performance parameter, comprise that absorber spring preloads, recovery damping force, pressesBefore contracting damping forces etc., the critical performance parameters of damping performance is fixed value, the adaptation model to car load in different road conditionsEnclose narrowly, can not meet the different user demands of different road conditions, adaptability is poor. Particularly for motorcycleDeng roadster, the scope of application is comparatively extensive, only adopts standardized shock absorber structure, can cause makingCan not be adapted to different environments for use with the motorcycle of damper of unified standard, the elastic force of spring is ledCause the principal element that comfortableness and reliability can not be coordinated well. And, under larger vibrations, momentThe distortion of spring extreme pressure can cause spring base and rigid contact of damping cylinder end cap, can affect the damping property of damperCan, affect road-ability simultaneously; And, because extreme pressure condition lower piston can touch at the end, cause damper dampingThe damage of assembly.
Therefore, need to improve damper, in larger vibration and while reaching damper limit travel, canLimited piston bar continues motion, avoids piston to touch the end or miscellaneous part rigidity contact damping cylinder, is beneficial to protection and livesPlug assembly and damping cartridge unit, the damping effect of guarantee damper, reduces shock absorber noise, raising comfortableness,Security and stationarity.
Utility model content
In view of this, the utility model provides the damping device of the anti-rigidity contact of a kind of damper, in larger vibrationAnd while reaching damper limit travel, can continue motion by limited piston bar, avoid piston to touch the end or other portionsPart rigidity contact damping cylinder, is beneficial to protection piston component and damping cartridge unit, ensures the damping effect of damper,Reduce shock absorber noise, improve comfortableness, security and stationarity.
The damping device of the anti-rigidity contact of damper of the present utility model, comprises for axially outside spacing being arranged atThe elastomeric damper member of piston rod; When use elastomeric damper member axially at least outwards (with respect to damping cylinder) relatively solidSurely be arranged on piston rod, generally adopt the spacing mode in axial two ends; Setting position ensure piston and damping cylinder orBetween the parts such as the spring base on person's piston rod and damping cylinder end cap, rigidity does not contact,, form effectively buffering, protectDemonstrate,proved comfortableness, the course of work more safety and stability is reliable; The mode that hydraulic cushion part is arranged on piston rod canAdopt catch spacing or utilize the spacing mode of other parts.
Further, described elastomeric damper member is that frustum structure and the frustum small end face that is coated at piston rod faces toward dampingCylinder; Spring shock absorption part is general to be adopted softer and has flexible material and make; Can be in damping extreme limit of travel situationUnder, power value increases gradually, is ensureing, on the reliable and stable basis of limiting case, to take into account comfortableness.
Further, also comprise damping spring, described damping spring is variable-pitch spring; Damping spring rigidity basisDifferent compressed state have difference, can adapt to the use of different loads situation, and according to the size of load notWith playing adaptive effect, in conjunction with the shock absorber part of frustum structure, first increase gradually damping force according to vibrations simultaneouslyAnd cushion effect, afterwards by the acting in conjunction gradually of elastomeric damper member, be beneficial to and improve the adaptation of product and improve comfortableProperty.
Further, the pitch of described damping spring is increased to piston rod direction gradually by the damping cylinder of damper; MakeUsed time piston rod generally upwards, on less vibrations or concavo-convex road surface, can ensure good flexibility, improvesComfortableness, along with pavement behavior variation, fine pith part works, ensure vehicle stability, security andComfortableness.
Further, described damping spring is coated at damping cylinder and piston rod simultaneously, a locking nut threaded engagement inDamping cylinder, locking nut is withstood in damping spring one end, and the other end withstands the bullet being connected at axial restraint with piston rodSpring abutment; Simple in structure, and spring travel is longer, due to the restriction effect of damping cylinder, effectively avoids spring and workThe rigidity contact causing because stroke is long between stopper rod, improves comfortableness.
Further, the large end face of described elastomeric damper member is near spring base; Effectively prevent spring base and damping cylinder endRigidity contact between lid, is beneficial to minimizing vibration noise, and makes all parts characteristics of compact layout rule.
The beneficial effects of the utility model: the damping device of the anti-rigidity contact of damper of the present utility model, adoptsElastomeric damper member structure is set on piston rod, the fixed connecting piece before at the bottom of piston rigid touch or on piston rodBefore touching with damping socket joint, the direct contact damping cylinder of this elastomeric damper member end cap, forms effectively buffering, is ensureing workWhile making extreme limit of travel situation, there will not be the undesirable conditions such as rigidity contact, ensured comfortableness, the course of work moreSafety and stability is reliable.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure: the anti-rigidity contact of damper of the present embodimentDamping device, comprise for the axial outwards spacing elastomeric damper member 5 that is arranged at piston rod 3; Bullet when useProperty shock absorber part axially at least outwards (with respect to damping cylinder 2) be relatively fixedly installed on piston rod 3, generally adoptThe axially spacing mode in two ends; Setting position ensures the spring base 4 on piston and damping cylinder 2 or piston rod 3Deng between parts and damping cylinder end cap not rigidity contact,, form effectively buffering, ensured comfortableness, workedCheng Gengjia safety and stability is reliable; Hydraulic cushion part be arranged at mode on piston 3 bars can adopt catch spacing orUtilize the spacing mode of other parts; Damper has piston component and damping cylinder, and piston component comprises piston rodAnd piston, belong to prior art, do not repeat them here.
