矿用自卸车前桥轮毂及其与车轮的联接结构
本技术属于矿用自卸车
,具体是涉及一种矿用自卸车前桥轮毂结构及其与车轮的联接结构。
技术介绍
电动轮自卸车是大型露天矿山物料运输的重要设备,其效率高低直接影响着矿产资源的开采成本。矿用自卸车前桥轮毂是前桥的组成部分,是自卸车的重要承载零件,其与车轮连接,将地面的传来支撑力传递给车轴。在前桥制动器维护维修时,或是前车轮需更换轮胎时都需要通过该联接将车轮从轮毂上拆下来,待维修更换完毕后安装上去。目前,有大型矿用自卸车前车轮轮毂结构如图1所示:车轮1与矿用自卸车前桥轮毂2是通过螺纹紧固件3和压块4联接到一起的。螺纹紧固件3一端拧入矿用自卸车前桥轮毂2,另一端利用螺母和压块4的限位作用,使得轮辋1和矿用自卸车前桥轮毂2的联接斜面上产生正压力,从而贴合在一起。与此类似轮毂与车轮的联接形式都有以下缺点:1)车轮的结构复杂,零件种类多,生产成本高。2)车轮拆卸和安装和拆装过程繁琐,过程费时费力。3)矿用自卸车前桥轮毂结构受力较差,矿用自卸车前桥轮毂与车轮的联接处在矿用自卸车前桥轮毂支撑的外侧,使得轮毂工作时的应力较大。4)矿用自卸车前桥轮毂受力较差,因而结构重量大,制造成本高,重量大,运行效率降低。5)由于矿用自卸车前桥轮毂的受力偏向一侧,矿用自卸车前桥轮毂联接轴承受力状态也较差,引起轴承的寿命较低。6)由于矿用自卸车前桥轮毂与车轮的联接偏向一侧,在工作尤其是满载工作时,将引起车轮变形较大,从而产生轮胎磨损两侧不均匀,轮胎寿命下降的情况。
