自卸車改裝設計畢業(yè)設計論文

摘要
去年以來，我國專用車市場取得較好的經(jīng)營業(yè)績，全國395家改裝車企業(yè)改裝汽車23.06萬輛，銷售23.05萬輛。自卸汽車27125輛，占總量的11.76％。隨著國內基礎設施建設需要不斷增加，自卸車產(chǎn)量近年來一直保持較高產(chǎn)銷量，在專用車綜合產(chǎn)量中保持第一位置，但在種類、型式、材料運用方面與國外還有一定的差距。
本文首先對自卸車的設計特點以及國內外發(fā)展現(xiàn)狀做了相關的概述。接著，從車廂的設計、舉升機構的設計、取力器的設計等方面進行了EQ3090自卸車的總體設計，并對主車副車架進行了改裝與設計。對整個EQ3090自卸車的外廓尺寸、輪距與軸距尺寸、前懸后懸以及整車的裝載質量、整備質量、總質量和軸載質量進行了相關的計算與設計。

Abstract
Since last year, our country Special Purpose Vehicle industry is in the boom, with 395 car refit enterprise all around the country refitting 230.6 thousand cars, selling 230.5 thousand. auto unload vehicle the 27125 car, account for 11.76% of total deal. along with the development of local foundation facilities, in recent years auto unload vehicle yield has been keeping in higher production & sales, remains in the first place in Special Purpose Vehicle production. However, in aspects of category, pattern, material application, compared with foreign countries there is still a long way to go.     In this paper, firstly, I made a general about the auto unload vehicle design and its development domestic and abroad. Then, at the point of compartment, rising organization etc, I started the design of the EQ3090 auto unload vehicle. Also, I refit and designed the vice-car stalk.
To whole EQ3090 the lading quantity, reorganization quantity, measure, tread, wheelbase, forward suspension behind，proceeded the related calculation and design.

Key words: auto unload vehicle  total arrangement  vice-car sta
