自動避障減震小車設(shè)計(jì)【含CAD圖紙+文檔】,含CAD圖紙+文檔,自動,減震,小車,設(shè)計(jì),cad,圖紙,文檔 摘 要 本次設(shè)計(jì)是對自動避障減震小車的設(shè)計(jì)。在這里主要包括:傳動系統(tǒng)的設(shè)計(jì)、臺架系統(tǒng)的設(shè)計(jì)、轉(zhuǎn)向系統(tǒng)的設(shè)計(jì)。這次畢業(yè)設(shè)計(jì)對設(shè)計(jì)工作的基本技能的訓(xùn)練，提高了分析和解決工程技術(shù)問題的能力，并為進(jìn)行一般機(jī)械的設(shè)計(jì)創(chuàng)造了一定條件。 整機(jī)結(jié)構(gòu)主要由電動機(jī)產(chǎn)生動力通過聯(lián)軸器將需要的動力傳遞到傳動軸上，傳動軸帶動萬向節(jié)聯(lián)軸器，帶動輪子，從而帶動整機(jī)裝置運(yùn)動，提高勞動生產(chǎn)率和生產(chǎn)自動化水平。更顯示其優(yōu)越性，有著廣闊的發(fā)展前途。 本論文研究內(nèi)容： (1) 自動避障減震小車的設(shè)計(jì)總體結(jié)構(gòu)設(shè)計(jì)。 (2) 自動避障減震小車的設(shè)計(jì)工作性能分析。 (3)電動機(jī)的選擇。 (4) 自動避障減震小車的設(shè)計(jì)的傳動系統(tǒng)、執(zhí)行部件及臺架設(shè)計(jì)。 (5)對設(shè)計(jì)零件進(jìn)行設(shè)計(jì)計(jì)算分析和校核。 (6)運(yùn)用計(jì)算機(jī)輔助設(shè)計(jì)，對設(shè)計(jì)的零件進(jìn)行三維建模。 (7)繪制整機(jī)裝配圖及重要部件裝配圖和設(shè)計(jì)零件的零件圖。 關(guān)鍵詞：自動避障減震小車的設(shè)計(jì)， 聯(lián)軸器，避障減震 Abstract This design is to design the automatic obstacle avoidance damping trolley. Here mainly includes: transmission system design, platform design, steering system design. The graduation design on the design of the basic skills training, enhancing the analysis and to solve engineering problems, and create a certain condition for general mechanical design. The structure is mainly produced by the motor power through the coupling will need to transmit power to the drive shaft, the drive shaft drives a universal coupling, drive the wheels, so as to drive the device, improve labor productivity and automation level of production. But also show its superiority, there are broad prospects for the development. The research of this thesis: (1) the design of overall structure design of automatic obstacle avoidance damping trolley. (2) analysis and design work performance of automatic obstacle avoidance of car shock absorber. (3) the choice of motor. (4) transmission system, design of the executive component and bench design of automatic obstacle avoidance damping trolley. (5) the design of components for the design calculation and check. (6) the use of computer aided design, 3D modeling on Design of parts. (7) to draw the assembly drawing and parts assembly diagram and parts diagram design.
