摘要：減震器又稱緩沖器，是安裝在摩托車懸掛裝置上的一個(gè)重要零件。摩托車懸掛裝置不僅決定了乘坐的舒適度，而且還是決定其運(yùn)動(dòng)性能的重要部件。而減震器的功能就是緩和由于路面不平引起的沖擊，衰減摩托車的振動(dòng)；提高乘坐舒適性，保護(hù)貨載；減低車體各部分的運(yùn)應(yīng)力，增加零件的壽命；加強(qiáng)輪胎的附著性，有助于摩托車的操縱性、穩(wěn)定性。
本文所設(shè)計(jì)的摩托車前減震器采用液力式減震方式，其工作行程為50 mm。通過彈簧減震為主。設(shè)計(jì)時(shí)減震彈簧采用組合式彈簧，由兩段節(jié)距不同的等節(jié)距圓柱彈簧組成。在通常振動(dòng)范圍內(nèi)，彈簧柔軟，當(dāng)車輛受到?jīng)_擊時(shí)，彈簧變硬，有足夠的能力吸收這種沖擊能量。減震器的機(jī)能是利用流體通過減震桿上的孔、隙產(chǎn)生的粘性阻力。和固體摩托減震相比，利用液體紊流阻力的減震器，在一定阻尼力和吸收能量的條件下，質(zhì)量小，尺寸小，并在相當(dāng)?shù)姆秶鷥?nèi)具有能任意規(guī)定阻尼力對(duì)工作速度的關(guān)系等優(yōu)點(diǎn)。
在設(shè)計(jì)過程中對(duì)前減震器的工作原理進(jìn)行了說明，并確定了工作部分主要零件的相關(guān)參數(shù)，在已知條件的前提下分別對(duì)減震彈簧直徑和自由高度，阻尼孔的數(shù)量和直徑等進(jìn)行設(shè)計(jì)計(jì)算。

Abstract : Dampers also known as buffer , is the installation of the hoisting device an important component . Motorcycle hoisting device will not only decide the ride comfort, but also to determine their performance movement of important parts . And the function of a shock absorber is easing due to the road surface uneven, the effect of vibration attenuation motorcycle; improveing ride comfort, Protection of cargo; reduceing the stress of the body operation, increaseing the life expectancy of components; strengthen tire adhesion. helping manipulation and stability of Motorcycle.
In this paper , motorcycle before shock absorber and the overall program analysis and design is the main content. Useing hydraulic shock absorber, its itinerary to 50 mm . Mainly through the spring damping, supplemented dampers. Damping spring design using modular spring，the combination of spring two such different pitchs pitch cylindrical spring,. In the normal range of vibration, soft spring, when the vehicles to be shocked, springs stiffen and have sufficient capacity to absorb the impact energy . Damper function use the fluid through the Absorption of shock pole on the hole, the gap viscous resistance . And compared to solid motorized damping, the use of liquid turbulent resistance dampers, to a certain damping force and absorb energy conditions, Quality small, size small, and the lack of scale with arbitrary requirements damping force on the relationship between the pace of work and so on.
In the process of designing,there are a note On the before shock absorber working principle , and to identify the major components of the work of the relevant parameters, Respectively damping springs, which includes determination and free height of the damping spring, Damping hole quantity and determination for the design and rehabilitation of resistance
Keywords ：before the shock absorber damping spring damper design
