Problems solved by technology

[0003] The components of the inline shaft-shaped planetary gear shaft set in the prior art are composed of a through shaft, and the components of the cross-shaft-shaped planetary gear shaft set are composed of two mutually fixed through shafts. When the differential is assembled The components of the two shapes of planetary gear shaft sets cannot be used interchangeably. The warehouse needs to be equipped with one through shaft and two mutually fixed through shafts at the same time, resulting in a large inventory

Abstract

The invention relates to an automobile accessory, and particularly relates to an automobile differential mechanism. The automobile differential mechanism comprises a shell, a half axle gear, an output shaft, a driven gear and planet gear shaft groups, wherein each planet gear shaft group is composed of a planet gear shaft A and a planet gear shaft B, and the planet gear shaft A and the planet gear shaft B of each group are disconnected to form a gap. Because each planet gear shaft group of the automobile differential mechanism is composed of each planet gear shaft A and each planet gear shaft B, the purpose of mixing components of the straight and cross shaft-shaped planet gear shaft group can be achieved only by manufacturing the planet gear shafts A and the planet gear shafts B. Especially, when the specification of each planet gear shaft A is the same as that of each planet gear shaft B, the straight and cross shaft-shaped planet gear shaft group can be assembled only by producing one kind of the planet gear shaft A or the planet gear shaft B.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to an automobile differential. Background technique [0002] The planetary gear shaft set of the differential is in the shape of a straight shaft (the differential is equipped with two planetary gears) or a cross shaft (the differential is equipped with four planetary gears). figure 1 It is a schematic diagram of an inline shaft-shaped planetary gear shaft set in the prior art, figure 2 It is a schematic diagram of a cross shaft-shaped planetary gear shaft set in the prior art, such as figure 1 and figure 2 As shown, in the prior art, the planetary gear shaft set is one or two through shafts that pass through the differential case and the middle part protrudes, and the protrusions are used to support the planetary gears, so that the planetary gears can surround the planetary gears The shaft group rotates. [0003] The components of the inline shaft-shaped planetary gear shaft set in ...
