The invention relates to a passenger car low-floor rear axle maintenance-free differential mechanism assembly structure which comprises a right differential mechanism bearing, a differential mechanism shell, a half axle gear, a planetary gear, a driven gear, a half axle gear gasket, a cross shaft, a left differential mechanism bearing and a planetary gear gasket. Cross shaft holes, oil groove holes and gear mounting holes are respectively formed in the integral differential shell, the cross shaft holes are two groups of shaft holes which are oppositely formed in the integral differential shell and are used for mounting cross shafts, the two groups of shaft holes form a cross shaft hole, the cross shafts comprise a long straight shaft and two short straight shafts, and the long straight shaft and the two short straight shafts are arranged in parallel. The long linear shaft is provided with inner round holes used for installing the short linear shafts, the two short linear shafts are connected with the long lin
