承重梁構造

1，承重梁(liang)選(xuan)用(yong)歐式古典箱型(xing)梁(liang)組織設計方案(an)，重量輕，合理(li)配置；

2，整個(ge)PCB線路板制做，無對接焊縫(feng)，比拼湊承(cheng)重梁更牢固。

3，豎直剛度(du)為(wei)1/800，梁端(duan)拱度(du)由數控(kong)切割整(zheng)個PCB線路(lu)板開料，精準度(du)高。

4，選用埋弧焊自動焊、無(wu)損檢測。焊后總體拋丸除銹，消(xiao)地應力、防銹處理，超過(guo)Sa2.5級；

5，厚鋼板原材(cai)料為Q235B；環氧富鋅(xin)漆，薄厚120μm。

端梁一部分

1，端梁(liang)選用絞(jiao)接軟性(xing)設計方案，防止“幾(ji)條(tiao)腿”運作。

2，車轱轆選用鏜孔方式，應用數控機床鏜銑床一回精準定位(wei)生產(chan)加(jia)工，保證(zheng)規格精密度(du)和(he)配合尺寸；

3，每一(yi)端梁裝有(you)雙輪緣的車轱轆(lu)、緩沖器(qi)、驅動器(qi)維(wei)護和防外遇保護器(qi)，安全性有(you)確保。

4，承(cheng)重梁(liang)與端梁(liang)選用10.9級(ji)高強螺(luo)栓聯接，保證整個(ge)設備構造抗壓強度和精密度。

5，半今(jin)龍門端梁選用(yong)矩(ju)形方管制做，車轱轆為無邊(bian)緣設計方案，路軌與路面(mian)每平米(mi)。

小轎車總程

1，雙梁(liang)(liang)小轎車承重梁(liang)(liang)與承重梁(liang)(liang)選用(yong)軟性絞接方式；防止“幾條腿”運作。

2，電動機＋制(zhi)動系統(tong)＋減速器＋行(xing)程開關四合一一體化(hua)設計(ji)方案，結構緊湊

3，小轎(jiao)車搭建有安全(quan)性(xing)鉤，防失控。

4，全部傳動系統(tong)組織選用(yong)無連軸器的(de)立即I/O方式，傳動系統(tong)高效率、裝配線高精度、免維護保養。

5，工作(zuo)中級(ji)別(bie)為A6級(ji)，防(fang)(fang)水等級(ji)IP55，H級(ji)絕緣層。防(fang)(fang)污防(fang)(fang)潮，提升安全級(ji)別(bie)。
