      支(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)的(de)作用(yong)是將挖掘(jue)(jue)機(ji)重(zhong)(zhong)(zhong)(zhong)量(liang)(liang)傳給地(di)面(mian)，當挖掘(jue)(jue)機(ji)在不平(ping)的(de)路(lu)面(mian)上行駛(shi)時(shi)支(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)會(hui)受地(di)面(mian)沖(chong)擊力，因(yin)此支(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)所(suo)受載荷大(da)，工作條件惡(e)劣，經常處于(yu)塵土(tu)中(zhong)，有時(shi)還浸泡在泥水中(zhong)，所(suo)以要求有良(liang)好的(de)密封。支(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)用(yong)螺釘(ding)固(gu)定(ding)在輪(lun)架下面(mian)，用(yong)于(yu)支(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)撐機(ji)械(xie)的(de)質(zhi)量(liang)(liang)，并將質(zhi)量(liang)(liang)分布在履(lv)帶(dai)板(ban)上。同時(shi)還依(yi)靠其滾輪(lun)凸緣夾持鏈軌(gui)不使履(lv)帶(dai)橫向(xiang)滑脫(tuo)（脫(tuo)軌(gui)），保(bao)證機(ji)械(xie)沿履(lv)帶(dai)方向(xiang)運動‘具(ju)有較(jiao)小(xiao)的(de)滾動阻力以及(ji)泥濘和水中(zhong)作業時(shi)具(ju)有的(de)壽命(ming)。在臺車架中(zhong)，特別是為提(ti)高剛度(du)而(er)裝置隔板(ban)時(shi)，形(xing)成的(de)一些(xie)空腔容易(yi)被泥土(tu)堵(du)塞(sai)而(er)阻礙支(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)轉動；在浸泡的(de)土(tu)壤(rang)上運行時(shi)，也容易(yi)堵(du)塞(sai)支(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)。因(yin)此，有一些(xie)履(lv)帶(dai)式推(tui)土(tu)機(ji)，在臺車架外側裝有帶(dai)加(jia)強筋(jin)的(de)支(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)護板(ban)。
