摘要
 摩托車減震器的種類多樣化，其作用便是迅速衰減摩托車震動，改善摩托車行駛平順性，由此，減震器的好壞及其重要，也是一輛摩托車檔次的體現，一款出色的減震器，可以提高摩托車操縱性和穩定性，減低車身部分載荷，延長摩托車使用壽命。
 本文簡要介紹了現今摩托車減震器的幾種類型，便重點介紹了氣囊式后減震器，這種減震器利用氣囊里面的高壓氮氣的回位功能，使得減震效果更明顯，主要包括液壓缸、活塞、活塞桿、上下連接頭、減震彈簧、導向座、阻尼閥片及油封，在油缸上端與上連接頭之間，固定連接有氣囊殼，其內腔與液壓缸內腔相連通，在氣囊殼內腔裝有充氣氣囊，利用里面的高壓氮氣，液壓缸下腔的油液能夠迅速阻止活塞的下移，既迅速阻止了減震彈簧的恢復彈升，使減震彈簧緩慢回升，減小了減震器對摩托車及其上的騎乘人員的沖擊，使減震器的減震效果更為理想，同時也減小了對摩托車造成的損害。
 與此同時，根據本課題所給的參數要求，在查閱了大量相應參考文獻的基礎上，確定了包括減震器阻尼系數等關鍵系數的選型；減震器大體尺寸的確定；以及減震彈簧及其活塞環的設計計算。最后通過計算并結合文獻，還對活塞桿的穩定性進行了校核，并繪制了相應的裝配圖與零件圖。本次設計主要是進行氣囊式減震器結構的選型及其重要零件的校核計算，以此達到加深對氣囊式減震器的了解的目的。

Abstract
 Diversify the types of motorcycle shock absorber, and its role in the rapid attenuation of motorcycle shock is to improve the smooth running of a motorcycle, which, good or bad shock absorbers and their importance is also the embodiment of the grade of a motorcycle, a excellent shock absorber section can be improved maneuverability and stability of motorcycle, car body parts to reduce the load, extend the life of a motorcycle.
 This paper introduces the present-day types of motorcycle shock absorber, it focuses on the post-shock absorber-type airbags, which make use of air inside the shock absorber of the high-pressure nitrogen-bit features to make more obvious the effect of damping, the main including tanks, piston, piston rod, upper and lower connector, shock absorber spring-oriented sets of regulators and the oil seal in the fuel tank on top and between the connector and fixed connections are airbag shell, the cavity with tanks cavity connected to pass, in the shell cavity balloon inflated with air, using high-pressure nitrogen gas inside, the fuel tank under the oil chamber to quickly stop the downward movement of the piston, both stop the rapid recovery of the shock absorber spring or shells, so that damping spring slow recovery, reducing the shock absorber of a motorcycle riding on the staff and the impact of the shock absorber damping effect so that more desirable, but also reduces the damage caused to the motorcycle.
 At the same time, under the subject to the parameters of the request, access to a large number of the corresponding basis of reference to determine the shock absorber damping, including the selection of the key factors; shock absorber performance eva luation; as well as the damping Spring Design and Calculation of their airbags. Finally, through the combination of calculated and literature, focusing on the hydraulic cylinder design and calculation, and the mapping of the corresponding parts of assembly drawings and plans. The airbag is designed to shock absorber damping coefficient calculation and the choice of damping spring, hydraulic cylinder design and calculation in order to achieve better understanding of airbag-type understanding of the purpose of shock absorber.
