Abstract

The invention discloses an output shaft support device for an automatic gearbox, and belongs to the technical field of the automatic gearbox. The output shaft support device for the automatic gearbox comprises an anti-thrust bearing and a radial bearing; an adjusting shim is installed between the ring of the anti-thrust bearing and the shell of the gearbox; the inner ring of the radial bearing is sleeved on the shaft shoulder of the output shaft; the outer side of the inner ring of the radial bearing bears against the output gear of the output shaft, and the inner side of the inner ring bears against the shaft ring of the anti-thrust bearing; the inner side of the outer ring of the radial bearing is provided with a flange; a spacer is installed between the flange and the shell of the gearbox; the outer ring of the radial bearing is fixedly installed with the shell of the gearbox; and the outer side of the outer ring of the radial bearing is provided with an opening. The output shaft support device for the automatic gearbox is capable of, through designing the radial bearing as the separated structure, solving the wearing problem of the gearbox shell, and solving the assembling problem of the radial bearing.

Description

technical field [0001] The invention belongs to the technical field of automatic transmissions, in particular to an output shaft support device for automatic transmissions. Background technique [0002] One end of the output shaft of the automatic transmission is connected to the planet carrier, and the other end is installed on the transmission case through a supporting device. The output shaft is provided with a shaft shoulder and an output gear sequentially from the inside to the outside. The supporting device includes bearings, and the bearings include cylindrical roller bearings for mainly bearing radial forces and thrust bearings for mainly bearing axial forces. The cylindrical roller bearings are installed on the shaft shoulders, and the outer ring of the cylindrical roller bearings and Gaskets are arranged between the gearbox casings, the thrust bearing is located at the end of the output shaft and an adjusting gasket is arranged between the thrust bearing and the ge...
