承重梁構造

1，承(cheng)重梁選用歐式古典箱型(xing)梁組織設計(ji)方(fang)案，重量輕，合理配置；

2，整(zheng)個PCB線路板制做，無對接焊縫，比(bi)拼湊承重梁(liang)更牢固。

3，豎直剛度(du)為1/800，梁端拱(gong)度(du)由數控切割整個PCB線(xian)路(lu)板開料，精準度(du)高。

4，選用埋弧焊(han)自(zi)動焊(han)、無(wu)損檢測。焊(han)后總體拋丸除銹，消地應力(li)、防(fang)銹處理，超過Sa2.5級；

5，厚鋼板原材(cai)料為(wei)Q235B；環氧(yang)富(fu)鋅漆(qi)，薄厚120μm。

端梁一部分

1，端梁選用絞接軟性(xing)設計方案，防止“幾條腿”運作(zuo)。

2，車轱(gu)轆選用鏜孔(kong)方式，應用數控機床(chuang)鏜銑床(chuang)一(yi)回(hui)精準定(ding)位生產加工，保證規格(ge)精密度和配合尺寸(cun)；

3，每一端(duan)梁裝有雙(shuang)輪緣的車(che)轱轆(lu)、緩沖(chong)器(qi)、驅動器(qi)維護和防外遇保護器(qi)，安全性有確保。

4，承(cheng)重梁(liang)(liang)與端梁(liang)(liang)選用10.9級高強(qiang)螺栓聯接，保證整個(ge)設備構造抗壓強(qiang)度和精密度。

5，半今龍門端梁選用矩形方管制做，車轱轆為(wei)無(wu)邊緣設計方案，路軌與路面每平米(mi)。

小轎車總程
