Abstract

The invention provides a gearbox differential mechanism. The gearbox differential mechanism is characterized in that a differential mechanism shell and a change gear set are arranged in a gearbox differential mechanism shell; a sun gear is arranged in the differential mechanism shell through a first output shaft and a second output shaft; a planet gear is connected with the sun gear through teeth; the first output shaft is arranged on the first differential mechanism shell through a second bearing; the second output shaft is arranged on the first differential mechanism shell through a third bearing; the change gear set is arranged between the differential mechanism shell and the gearbox differential mechanism shell, and is fixed relative to the third bearing; one end of the change gear set is connected with a second transformation component through a fourth bearing; and the second bearing is connected with a first transformation component through a first bearing. By adopting the gearbox differential mechanism, a left driving wheel and a right driving wheel or a front driving wheel and rear driving wheel can rotate at different speeds; besides, gears in the differential mechanism and the gears in a gearbox can be cooled, so that the service life of the gearbox differential mechanism is prolonged; and the gears in the differential mechanism can be lubricated, so that the servicelife of the differential mechanism is effectively prolonged.

Description

technical field [0001] The invention relates to the field of differentials, in particular to a gearbox differential. Background technique [0002] A vehicle differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier. The function is to make the left and right wheels roll at different speeds when the car is turning or driving on an uneven road, that is, to ensure the pure rolling motion of the driving wheels on both sides. The differential is installed to adjust the speed difference between the left and right wheels. When the car is turning, the turning radius of the inner wheel and the outer wheel is different, and the turning radius of the outer wheel is larger than that of the inner wheel, which requires that the speed of the outer wheel is higher than that of the inner wheel when turning. The role of the diffe...
