2，車轱轆選用鏜孔方式，應用數控機床(chuang)鏜銑(xian)床(chuang)一(yi)回精準定(ding)位生產加工，保證規(gui)格精密(mi)度和配合尺寸；

3，每一端梁裝有雙輪緣的(de)車轱轆、緩沖(chong)器(qi)、驅動器(qi)維護和防(fang)外遇保護器(qi)，安全性有確保。

4，承重梁(liang)與端梁(liang)選用10.9級(ji)高強螺栓聯接(jie)，保證整個設備構(gou)造抗壓強度和精密度。

5，半今(jin)龍門端梁(liang)選用(yong)矩形方管制做，車轱(gu)轆為無邊緣(yuan)設計方案，路(lu)軌與路(lu)面每平米。

小轎車總程

1，雙梁(liang)小轎(jiao)車承重梁(liang)與承重梁(liang)選用軟(ruan)性絞(jiao)接方式；防止“幾(ji)條腿”運作。

2，電動(dong)機＋制動(dong)系統(tong)＋減速器＋行(xing)程開關四(si)合一一體化(hua)設計方(fang)案，結(jie)構緊湊(cou)

3，小(xiao)轎(jiao)車搭建有安全性鉤，防失控。

4，全部傳動系(xi)統組織選用無(wu)連軸器的立即I/O方式，傳動系(xi)統高(gao)效率、裝配線高(gao)精度(du)、免維護保養。

5，工(gong)作中(zhong)級(ji)(ji)別為A6級(ji)(ji)，防(fang)(fang)水等級(ji)(ji)IP55，H級(ji)(ji)絕(jue)緣層(ceng)。防(fang)(fang)污防(fang)(fang)潮，提(ti)升安(an)全級(ji)(ji)別。
