Problems solved by technology

When the differential housing wears too much, the side clearance between the side gear and the planetary gear will be too large, resulting in increased noise of the differential, and the drive line of the side gear and the planetary gear will be deflected, resulting in toothing, In severe cases, the differential assembly will be damaged

Embodiment Construction

[0008] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail;

[0009] Such as figure 1 As shown, a differential case wear-resistant differential consists of a left differential case 1, a right differential case 2, a side gear 3, a side gear spacer 4, a planetary gear 5, a planetary gear spacer 6 and The cross shaft 7 is composed; the side gear gasket 4 is respectively fixed on the inner walls of the left differential case 1 and the right differential case 2 through positioning pins 8 . The dimension from the outer end of the positioning pin to the outer surface of the side gear gasket is greater than 2MM.

[0010] The detailed implementation process is to drill three holes on the side gear spacer 4, and process three holes with the same index on the left and right differential cases at the same time, and use three positioning pins 8 that have been calculated in detail to place the three holes. It locks, g...

Abstract

The invention discloses a differential mechanism with an anti-wearing differential shell. The differential mechanism consists of a left differential mechanism shell, a right differential mechanism shell, a half axle gear, half axle gear gaskets, a planetary gear, a planetary gear gasket and a cross shaft, wherein the half axle gear spacers are respectively fixed on inner walls of the left differential mechanism shell and the right differential mechanism shell through location pins. The half axle gear gaskets and the differential mechanism shells are locked to be an integral structure by a location pin structure; the relative movement among the differential mechanism shell, the half axle gear gaskets and the half axle gear is changed to be relative movement between the half axle gear and the differential mechanism shell as well as between the half axle gear gaskets and the differential mechanism shell. Therefore, when the relative movement between the two exists, the gear only can wear the half axle gear spacers and cannot wear the differential mechanism shell; and the half axle gear gaskets are easy to change, so that the cost is low, and the maintenance is simple and convenient.

Description

technical field [0001] The invention relates to the field of automobile driving axles, in particular to a differential housing anti-wear differential. Background technique [0002] At present, the structure of the differential in the automobile drive axle is composed of the left and right differential case, the side gear, the side gear spacer, the planetary gear, the planetary gear spacer, and the cross shaft structure, and the side gear spacer and the half shaft The shaft gears can rotate relative to each other. When the differential acts as a differential, the planetary gears and side gears in the differential not only revolve together with the differential assembly, but also rotate themselves. During the process of rotation, gears, gaskets and housings are bound to The relative movement between gears is generally harder and the shell material is softer than the gear material, so the differential case wears more seriously during relative rotational friction. When the dif...
