承重梁構造

1，承重梁選(xuan)用歐式古(gu)典箱型梁組織設計方案(an)，重量輕，合理配(pei)置；

2，整(zheng)個PCB線路板制(zhi)做，無對接焊(han)縫，比(bi)拼(pin)湊承重(zhong)梁更(geng)牢固。

3，豎直(zhi)剛度為1/800，梁端拱(gong)度由數控(kong)切割整個PCB線路板(ban)開料，精(jing)準度高(gao)。

4，選用埋(mai)弧(hu)焊(han)(han)自動焊(han)(han)、無損檢測。焊(han)(han)后總體拋(pao)丸除(chu)銹，消地應力、防銹處理(li)，超過(guo)Sa2.5級；

5，厚(hou)鋼板原材料(liao)為Q235B；環氧富鋅漆，薄厚(hou)120μm。

端梁一部分

1，端梁選(xuan)用絞接軟(ruan)性(xing)設計方(fang)案，防(fang)止(zhi)“幾條腿”運作。

2，車轱轆選用鏜(tang)孔(kong)方式(shi)，應用數控機(ji)床鏜(tang)銑床一回精(jing)準定位生產加工，保證(zheng)規格精(jing)密(mi)度(du)和配合(he)尺寸；

3，每一端梁裝有雙輪緣的(de)車轱(gu)轆(lu)、緩沖器(qi)、驅(qu)動(dong)器(qi)維護(hu)和防外遇保護(hu)器(qi)，安全性有確保。

4，承重梁與端(duan)梁選用10.9級高強螺栓聯接，保證整個設備構(gou)造抗壓(ya)強度(du)和(he)精密度(du)。

5，半今龍門(men)端梁選用矩形(xing)方(fang)管制做，車轱轆(lu)為無邊緣設計方(fang)案，路軌與路面(mian)每平米。

小轎車總程

1，雙梁小(xiao)轎(jiao)車承(cheng)重梁與承(cheng)重梁選用軟性絞接方式(shi)；防止“幾條腿”運作(zuo)。

2，電動(dong)(dong)機＋制動(dong)(dong)系統＋減速器＋行程開關四(si)合一一體化設計(ji)方(fang)案，結構緊湊

3，小轎車(che)搭建有(you)安全性鉤，防(fang)失控。

4，全(quan)部傳動系(xi)統(tong)組織選用無連軸(zhou)器的立即I/O方式，傳動系(xi)統(tong)高效(xiao)率、裝配線(xian)高精度、免維(wei)護保(bao)養(yang)。

5，工作中(zhong)級別為(wei)A6級，防(fang)水等級IP55，H級絕緣層。防(fang)污防(fang)潮，提升安全(quan)級別。
