承重梁構造

1，承重(zhong)梁選(xuan)用歐式古(gu)典箱型梁組織(zhi)設計方案，重(zhong)量輕，合理(li)配置；

2，整個PCB線路(lu)板制做，無(wu)對接焊(han)縫，比拼湊承重梁更牢固(gu)。

3，豎直剛度為1/800，梁端拱度由數控切(qie)割整個PCB線路(lu)板開料，精(jing)準度高。

4，選用埋弧焊自動焊、無損(sun)檢測。焊后總體拋丸除銹，消地應力、防銹處理，超過Sa2.5級；

5，厚鋼(gang)板原材料為Q235B；環氧富鋅漆，薄(bo)厚120μm。

端梁一部分

1，端梁(liang)選用絞接軟性設計方(fang)案，防止“幾條腿”運作。

2，車轱轆選用鏜孔方式，應用數控機床鏜銑床一回(hui)精(jing)準定位(wei)生產加工(gong)，保(bao)證規(gui)格精(jing)密度(du)和配合尺寸；

3，每一端梁裝(zhuang)有(you)雙(shuang)輪緣的車轱轆、緩(huan)沖(chong)器、驅動(dong)器維護和(he)防外遇保(bao)護器，安全性(xing)有(you)確(que)保(bao)。

4，承(cheng)重(zhong)梁與端(duan)梁選用10.9級高強螺(luo)栓聯接，保(bao)證整個設備構(gou)造抗壓強度和(he)精密度。

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

小轎車總程

1，雙(shuang)梁小轎(jiao)車承重梁與承重梁選用軟性(xing)絞接方式(shi)；防(fang)止“幾條腿”運(yun)作。

2，電動機(ji)＋制(zhi)動系(xi)統＋減速(su)器(qi)＋行程(cheng)開關四合一一體(ti)化設計方(fang)案，結構緊湊

3，小轎車搭建有安全(quan)性鉤，防(fang)失控。

4，全(quan)部傳動系(xi)統組織選用(yong)無連軸(zhou)器的(de)立即I/O方式(shi)，傳動系(xi)統高(gao)效率、裝配線高(gao)精度、免維護保(bao)養。

5，工作中(zhong)級(ji)別(bie)為(wei)A6級(ji)，防(fang)(fang)水等(deng)級(ji)IP55，H級(ji)絕(jue)緣層。防(fang)(fang)污防(fang)(fang)潮，提升安全級(ji)別(bie)。
