承重梁構造

1，承重梁(liang)選用歐式古典箱型梁(liang)組織設(she)計方案，重量輕，合理配置；

2，整個PCB線(xian)路板制做，無對(dui)接焊縫，比拼湊承重梁更牢(lao)固。

3，豎(shu)直剛度(du)為1/800，梁端拱(gong)度(du)由數(shu)控切割整個PCB線路板開料，精準度(du)高。

4，選(xuan)用埋弧焊(han)自動(dong)焊(han)、無損(sun)檢(jian)測。焊(han)后總(zong)體拋丸除(chu)銹，消地(di)應力、防(fang)銹處(chu)理，超(chao)過Sa2.5級；

5，厚(hou)鋼板原材料為Q235B；環氧富(fu)鋅漆，薄厚(hou)120μm。

端梁一部分

1，端梁選用絞接軟(ruan)性設(she)計方案(an)，防止(zhi)“幾條腿”運作。

2，車(che)轱轆選用(yong)鏜孔方式，應用(yong)數控機床鏜銑床一回精準定位生(sheng)產加工，保證規格精密度和配合尺寸；

3，每(mei)一端梁裝有雙(shuang)輪緣的車轱(gu)轆、緩沖器(qi)、驅動器(qi)維護和防外遇保護器(qi)，安全性有確保。

4，承重梁與端(duan)梁選用(yong)10.9級高強(qiang)(qiang)螺栓聯接，保證(zheng)整個(ge)設備(bei)構造抗壓強(qiang)(qiang)度(du)和精密度(du)。

5，半今龍門端梁選(xuan)用矩形方管制做，車轱(gu)轆為無邊(bian)緣設計方案，路軌與路面每(mei)平米。

小轎車總程

1，雙梁小轎車承重(zhong)梁與承重(zhong)梁選(xuan)用軟性(xing)絞接方式；防(fang)止“幾條腿”運作。

2，電動(dong)(dong)機(ji)＋制動(dong)(dong)系統(tong)＋減速器＋行(xing)程開關四(si)合一(yi)一(yi)體化設計方(fang)案，結構(gou)緊湊(cou)

3，小轎車搭(da)建有安全性鉤(gou)，防失控(kong)。

4，全部傳動(dong)系統(tong)組織選用無(wu)連(lian)軸器的立(li)即(ji)I/O方式，傳動(dong)系統(tong)高效率、裝配(pei)線高精度、免(mian)維護(hu)保養。

5，工作中級別(bie)為A6級，防(fang)水(shui)等級IP55，H級絕緣層。防(fang)污防(fang)潮，提升安全(quan)級別(bie)。
