Abstract

The invention provides a box assembly, an automatic gearbox and an automobile. The box assembly comprises a box body and a box cover; at least two axial grooves are formed in the circumferential direction on the end portion of the box body; a through hole which penetrates through the thickness of the box body is formed between the two axial groove; at least two tooth-shaped projections are formed in the circumferential direction of the box cover edge; a boss which protrudes the box cover surface is arranged between the two tooth-shaped projections; the axial grooves are matched with the tooth-shaped projections; the through hole is matched with the boss. According to the technical scheme, the axial grooves and the tooth-shaped projections are formed due to machining based on original structures of the box body and the box cover and the axial length of the axial grooves and the tooth-shaped projections does not increase, so that 3 to 4 mm space in the axial direction of the box body and the box cover is saved, which is meaningful to shrink of the axial size of small products.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a box assembly, an automatic gearbox and an automobile. Background technique [0002] On the existing automobile, the casing of the automatic transmission is placed horizontally. The automatic transmission includes a case body, a planetary gear arranged inside the case body, and a case cover for sealing the case body. In the actual installation process, the planetary gear is first installed inside the box, and then the box cover is fixed to the box body, and the box cover and box body are fixed by snap-fitting. Specifically, a snap ring groove is provided on the box body, and a boss is arranged on the box cover, and the boss is matched and fixed with the snap ring groove. [0003] At least the following problems exist in the current technology: the use of buckle-type fixing will occupy a space of 3mm-4mm in the axial direction of the box body and the box cover.
