摘 要
礦用防爆越野車是礦藏開采行業(yè)迫切需要的生產(chǎn)設(shè)備之一。從2008年4月起，國家安全監(jiān)督局已下文明令禁止井下使用非防爆車輛。懸架是現(xiàn)代汽車上的重要總成之一，它把車架(或車身)與車軸(或車輪)彈性地連接起來。其主要任務(wù)是傳遞作用在車輪和車架(或車身)之間的一切力和力矩;緩和路面?zhèn)鹘o車架(或車身)的沖擊載荷，保證汽車的行駛平順性;保證車輪在路面不平和載荷變化時有理想的運動特性。
本文設(shè)計的主要內(nèi)容有：(1)闡述了前后懸架的特點，確定了前后懸架為雙橫臂獨立懸架后懸架為鋼板彈簧非獨立懸架的設(shè)計方案，確定懸架的結(jié)構(gòu)形式及主要參數(shù)。(2)對前后懸架的彈簧進(jìn)行設(shè)計計算，對主要零部件進(jìn)行相應(yīng)的校核，完成前后懸架減震器的匹配，對減振器的主要參數(shù)進(jìn)行計算及其相關(guān)的校核。(3)對懸架的導(dǎo)向機(jī)構(gòu)的設(shè)計，完成懸架導(dǎo)向機(jī)構(gòu)的設(shè)計方案，確定了懸架導(dǎo)向機(jī)構(gòu)的布置參數(shù)，完成了前懸架上下橫臂在縱向平面和在橫向平面上的布置方案，確定上下橫臂的長度。

ABSTRACT
Mining SUV explosion－Proof vehicles is one of urgently needed Production equipment in Coal mining industry.Sinee04.2008 the national security agency has banned the use of underground un－explosion－proof vehicles.Modern automobile suspension is one of the important assembly on the frame, it (or body) and axle (or wheel) elastic ground joined up.Its main task is to transfer function and frame (or in the wheels of the body) all force and torque between; Ease road to frame (or body), ensure the impact load of car ride comfort and sex; Ensure the wheels and the load changes in pavement uneven has ideal motion characteristics.
The main content of this design：(1)Expounds the characteristics of before and after suspension, Sure the front suspension for double wishbone suspension for steel plate after suspension spring to the independent suspension design scheme, sure suspension structure form and main parameters(2)Before the spring of suspension design calculation of main components, make corresponding road-line; suspension damper before and after the match, the main parameters of shock absorber is calculated and related dynamicrigidity.(3)The steering mechanism for suspension, complete suspension of design, the design of steering mechanism of suspension steering mechanism to determine the layout parameters, completed the front suspension fluctuation wishbone in the longitudinal plane and transverse plane arrangement plan, determine the length of the arm up and down.
