Problems solved by technology

As a front-drive transmission of a front-wheel drive vehicle, it is necessary to integrate and assemble the differential structure inside the front-drive transmission housing. However, the existing differential structure is either large in size or unreasonable in structure, and due to the existing differential structure. The planetary gear shaft used is usually processed into four radially extending shafts on an integrally formed central body, and the four planetary gears are respectively supported on the planetary gear shafts. When assembling inside the transmission housing, the assembly process is complicated. It is not conducive to installation and operation, which seriously affects the design improvement of reducing the size of the front drive transmission, which is not conducive to the development of front drive vehicles

Abstract

The invention discloses a differential mechanism assembly of an automobile front-wheel drive transmission. The opposite ends of a differential mechanism shell and a shell end cover are provided with assembling limiting flanges correspondingly; a main reduction gear is arranged on the assembling limiting flange of the differential mechanism shell cover in a sleeving mode and clamped between the differential mechanism shell and the differential mechanism shell cover; two semi-shaft bevel gears are symmetrically installed in a gear mechanism installation cavity; the shell wall of the differentialmechanism shell is uniformly divided into 360 degrees and provided with four radial through holes; a planet gear shaft forms a cross-shaped shaft through a long shaft and two short shafts, the two ends of the long shaft are in clearance fit with the two opposite radial through holes on the differential mechanism shell, one ends of the two short shafts are connected to the long shaft in an axiallysymmetrical mode, and the other ends of the two short shafts are in clearance fit with the other two radial through holes on the differential mechanism shell; and four planet gears are in clearance fit with the four ends of the cross-shaped shaft and are engaged with the two semi-shaft bevel gears through the same teeth.

Description

technical field [0001] The invention relates to the field of differential gears, in particular to a differential gear assembly of an automobile front drive transmission. Background technique [0002] Usually, there are many components installed in the front engine compartment of a front-wheel drive vehicle, such as the engine, transmission, etc., which limits the design space of components. Make the structure as compact and reasonable as possible. As a front-drive transmission of a front-wheel drive vehicle, it is necessary to integrate and assemble the differential structure inside the front-drive transmission housing. However, the existing differential structure is either large in size or unreasonable in structure, and due to the existing differential structure. The planetary gear shaft used is usually processed into four radially extending shafts on an integrally formed central body, and the four planetary gears are respectively supported on the planetary gear shafts.
