摘要
萬向節(jié)滑動(dòng)叉位于傳動(dòng)軸的端部。它的主要作用：一是傳遞扭矩，使汽車獲得前進(jìn)的動(dòng)力；二是當(dāng)汽車后橋鋼板彈簧處在不同的狀態(tài)時(shí)，由本零件可以調(diào)整傳動(dòng)軸的長(zhǎng)短及其位置。零件的兩個(gè)叉頭部位上有兩個(gè)孔，用以安裝滾針軸承并與十字軸相連，起萬向聯(lián)軸節(jié)的作用。零件上的花鍵孔與傳動(dòng)軸端部的花鍵軸相配合，用于傳遞動(dòng)力之用。
本設(shè)計(jì)主要編制該零件的機(jī)械加工工藝規(guī)程，并設(shè)計(jì)其中兩道工序的專用夾具，并撰寫設(shè)計(jì)說明書。此次設(shè)計(jì)培養(yǎng)了我熟悉并運(yùn)用有關(guān)手冊(cè)、規(guī)范、圖表等技術(shù)資料的能力。進(jìn)一步鍛煉了我識(shí)圖、制圖、運(yùn)算、編寫技術(shù)文件和操作CAD等基本能力。

Abstract
Fork sliding universal joints at the end of the shaft. Its main roles: First, transfer torque to the driving force for car access to move forward; second is when the vehicle rear axle leaf spring in a different state, the parts can be adjusted by the length of shaft and its location. Parts the first part of the two forks, there are two holes for the installation of needle bearings and connected with the cross-axis, since the role of universal coupling. Parts of the spline hole and the shaft end of the spline shaft of it, for power transmission purposes.
The design of the main components of the preparation of the machining process planning and design processes in which two special fixture to work together and write a design specification. The design of the training I am familiar with and use of the manual, specification, diagrams and other technical information. Further training of my knowledge map, drawing, calculations, preparation of technical documents and the basic ability to operate CAD.
