承重梁構造

1，承重梁(liang)選用歐(ou)式古典(dian)箱型(xing)梁(liang)組織設計方案(an)，重量(liang)輕，合理配置；

2，整個PCB線(xian)路板制做，無對接焊縫，比(bi)拼湊承重梁更牢固。

3，豎(shu)直剛度(du)為(wei)1/800，梁(liang)端(duan)拱度(du)由數控切割(ge)整個(ge)PCB線(xian)路板(ban)開料，精(jing)準度(du)高。

4，選(xuan)用埋弧焊自動焊、無損檢測(ce)。焊后總體拋丸除銹，消(xiao)地(di)應力(li)、防銹處理(li)，超過Sa2.5級；

5，厚鋼板原材料為Q235B；環氧富鋅漆，薄厚120μm。

端梁一部分

1，端梁選用絞接軟(ruan)性設計方案，防止“幾條(tiao)腿(tui)”運作。

2，車轱轆選用鏜(tang)孔方(fang)式，應用數控機(ji)床(chuang)鏜(tang)銑床(chuang)一(yi)回精準定位(wei)生產加(jia)工(gong)，保證規格精密度和(he)配合(he)尺寸；

3，每一端梁裝有雙輪(lun)緣的車轱轆、緩沖器、驅(qu)動器維護(hu)和防(fang)外遇保護(hu)器，安(an)全(quan)性有確保。

4，承(cheng)重梁與端(duan)梁選用10.9級高(gao)強螺栓聯接，保證整個設備構造(zao)抗壓強度和精密度。

5，半今龍門端梁選(xuan)用(yong)矩形方(fang)管(guan)制做，車轱轆為無邊緣(yuan)設計方(fang)案，路軌與路面每平(ping)米。

小轎車總程

1，雙梁(liang)(liang)小(xiao)轎車(che)承(cheng)重梁(liang)(liang)與承(cheng)重梁(liang)(liang)選用軟(ruan)性絞接方式；防止“幾條腿”運作。

2，電動機＋制動系(xi)統＋減速器＋行(xing)程開關四(si)合一一體化(hua)設計方案，結構緊湊(cou)

3，小轎車搭(da)建有(you)安全(quan)性鉤，防失控(kong)。

4，全部傳(chuan)動(dong)系(xi)統組織選用無連(lian)軸器的立即I/O方式，傳(chuan)動(dong)系(xi)統高(gao)效率(lv)、裝(zhuang)配線高(gao)精(jing)度(du)、免維護保養。

5，工(gong)作中級(ji)(ji)別為A6級(ji)(ji)，防(fang)水等級(ji)(ji)IP55，H級(ji)(ji)絕(jue)緣層。防(fang)污防(fang)潮，提升安全(quan)級(ji)(ji)別。
