Abstract

The invention discloses a firm supporting and smooth lubricating type differential mechanism assembly which comprises a differential mechanism left shell (1), a differential mechanism right shell (2),cross shaft long shafts (3), long shaft short shafts (4), half shaft wheels (6), half shaft wheel gaskets (7), planet gears (8), planet gear gaskets (9), a differential mechanism left bearing (11) and a differential mechanism right bearing (12). The firm supporting and smooth lubricating type differential mechanism assembly is characterized in that milling flat planes are arranged on the cross shaft long shafts (3) and the long shaft short shafts (4) correspondingly; a cross shaft fixed sleeve is fixed to a cross shaft assembly formed by the cross shaft long shafts (3) and the long shaft short shafts (4); and anti-loose bolts (10) are fixedly mounted in the differential mechanism right shell (2) through a mounting plane, and the anti-loose bolts (10) penetrate into blind holes of the cross shaft long shafts (3) and the long shaft short shafts (4). By means of the differential mechanism assembly, the rigidity of a split cross shaft is greatly enhanced, the position precision of work ofhalf shafts and the planet gears is guaranteed, outer component damage brought by the situation that the cross shaft moves out of a differential mechanism is avoided, and work and operation of innercomponents of the differential mechanism assembly under the good lubricating condition are facilitated.

Description

Technical field: [0001] The invention relates to the technical field of automobile axles, in particular to a firmly supported and smoothly lubricated differential gear assembly. Background technique: [0002] At present, for the differential assembly of heavy trucks, there is an ordinary structure, that is, the cross shaft is an integral type, and the structure is assembled between the left and right shells of the differential. The second is the "sandwich" structure that has been widely developed in recent years. , in order to increase the supporting rigidity of the driven bevel gear of the main reducer, the flange mounting surface with the left case of the differential is added on the right case of the differential, so that the driven bevel gear in the original ordinary structure is only installed in the differential The left case of the transmission is installed on the two flanges of the left case and the right case. In contrast, the support of the right case of the differ...
