承重梁構造

1，承重(zhong)梁選用歐式古典箱型梁組織設(she)計方案，重(zhong)量輕，合理配置；

2，整個PCB線路板制(zhi)做，無對(dui)接焊縫，比拼湊承重梁更(geng)牢固。

3，豎直(zhi)剛度(du)為1/800，梁端拱度(du)由數控切割整個PCB線(xian)路板開料，精準度(du)高。

4，選用埋弧焊自動焊、無損檢測。焊后總體拋(pao)丸除銹(xiu)，消地應力(li)、防銹(xiu)處理，超過Sa2.5級；

5，厚(hou)鋼板原(yuan)材料為Q235B；環氧富鋅漆(qi)，薄厚(hou)120μm。

端梁一部分

1，端梁(liang)選(xuan)用(yong)絞接軟性設(she)計方案，防止“幾條腿”運(yun)作。

2，車轱轆(lu)選用鏜孔方式，應用數(shu)控機床鏜銑床一回精(jing)準定(ding)位生產加(jia)工，保證規格精(jing)密度和配(pei)合尺寸(cun)；

3，每(mei)一(yi)端梁(liang)裝有雙(shuang)輪(lun)緣的車轱轆、緩(huan)沖器(qi)、驅動器(qi)維護和防外遇保護器(qi)，安全性(xing)有確(que)保。

4，承重梁與(yu)端(duan)梁選用10.9級高(gao)強螺(luo)栓(shuan)聯接(jie)，保證整個設備構(gou)造抗壓強度(du)和精密度(du)。

5，半(ban)今龍門(men)端梁(liang)選用矩形(xing)方(fang)管制做，車轱轆為(wei)無(wu)邊緣設計方(fang)案，路軌(gui)與(yu)路面每平(ping)米。

小轎車總程

1，雙梁(liang)小轎車(che)承重(zhong)梁(liang)與承重(zhong)梁(liang)選用軟性絞接方(fang)式；防止“幾條腿”運作。

2，電動機＋制動系統＋減速(su)器＋行程開關四合一一體化設計方(fang)案(an)，結構緊湊

3，小轎車(che)搭建有(you)安全性(xing)鉤，防失(shi)控。

4，全(quan)部(bu)傳動系統組織(zhi)選用無(wu)連軸器的立即I/O方(fang)式，傳動系統高效(xiao)率、裝配線高精度、免維護保(bao)養。

5，工作中級(ji)(ji)別為A6級(ji)(ji)，防水(shui)等級(ji)(ji)IP55，H級(ji)(ji)絕(jue)緣層。防污防潮(chao)，提升(sheng)安(an)全(quan)級(ji)(ji)別。
