矿用自卸车D形分体式后桥壳总成
本专利技术涉及一种矿用自卸车,具体是,涉及一种矿用自卸车D形分体式后桥壳总成。
技术介绍
矿用自卸车是露天采矿重要的运输设备,车辆在使用过程中,后桥壳总成承担了约70%的载荷,而且矿用自卸车的使用环境恶劣,因此对后桥壳总成的强度和疲劳寿命要求高。现有的技术方案是:后桥壳和半轴套管分别铸造,再焊接在一起。现有方案的缺点是,后桥壳与半轴套管焊接的过程中,受操作者水平、环境温度、环境湿度等因素影响较大,焊接过程中易产生焊接缺陷,影响后桥壳总成的疲劳寿命。另外车辆在使用过程中,如果一侧的半轴套管损坏,必须将整个后桥壳总成从车上拆下来进行修复,拆装过程复杂,不利于后桥壳总成的维护。
技术实现思路
本专利技术所解决的技术问题是提供一种矿用自卸车D形分体式后桥壳总成,半轴套管与后桥壳通过螺栓连接在一起,制造过程受外界因素影响小,同时半轴套管易于从车辆上拆装。技术方案如下:一种矿用自卸车D形分体式后桥壳总成,包括:后桥壳、半轴套管、螺栓,两个半轴套管通过螺栓分别连接在后桥壳两端;后桥壳的两端设置有内圆柱面,内圆柱面外侧后桥壳的端部设置有D形螺纹孔组;半 ...
