承重梁構造

1，承(cheng)重(zhong)梁選用歐(ou)式古(gu)典(dian)箱型梁組(zu)織設計方(fang)案，重(zhong)量輕(qing)，合理配置；

2，整個PCB線路板制做，無(wu)對接焊縫，比拼湊承重梁更牢(lao)固。

3，豎直剛度為1/800，梁端(duan)拱度由數控切割整個PCB線路板開(kai)料，精準度高。

4，選用埋(mai)弧(hu)焊自動(dong)焊、無損檢測(ce)。焊后總體(ti)拋丸(wan)除銹，消地應力、防銹處理，超過Sa2.5級(ji)；

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

端梁一部分

1，端梁選(xuan)用絞接(jie)軟(ruan)性(xing)設計方案，防止“幾條(tiao)腿(tui)”運作。

2，車轱轆選用(yong)鏜(tang)孔方式，應(ying)用(yong)數(shu)控(kong)機床鏜(tang)銑床一回精準定位(wei)生產加(jia)工，保(bao)證規格(ge)精密度和(he)配合尺(chi)寸；

3，每一端(duan)梁裝(zhuang)有雙輪(lun)緣的車轱轆、緩(huan)沖器(qi)、驅動器(qi)維(wei)護(hu)(hu)和(he)防外遇保(bao)護(hu)(hu)器(qi)，安全性(xing)有確保(bao)。

4，承重梁(liang)與端(duan)梁(liang)選用(yong)10.9級高強螺栓聯接，保證整個設備構造抗壓強度和精密度。

5，半今龍門端梁選用矩形方管制做，車轱轆(lu)為無(wu)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)小轎車承重(zhong)梁(liang)與承重(zhong)梁(liang)選(xuan)用軟性絞接(jie)方(fang)式；防止“幾(ji)條腿”運(yun)作(zuo)。

2，電動(dong)機＋制動(dong)系統＋減(jian)速器＋行程開關四合一(yi)一(yi)體(ti)化設計方(fang)案，結構緊湊(cou)

3，小轎(jiao)車搭建有安全性鉤，防失控。

4，全部傳動系統組織選用無連軸器的立即I/O方式，傳動系統高效率、裝配線高精度、免維護保養。

5，工作中(zhong)級(ji)別為A6級(ji)，防(fang)(fang)水等(deng)級(ji)IP55，H級(ji)絕(jue)緣(yuan)層。防(fang)(fang)污防(fang)(fang)潮，提升安全(quan)級(ji)別。
