Technical field
The utility model relates to mechanical technique, relates in particular to a kind of chest assembly, automatic transmission case and automobile.
Background technique
On existing automobile, the casing of automatic transmission case is horizontal.Automatic transmission case comprises casing, is arranged on the planetary pinion of box house and the case lid that is used for seal case.In the as installed process, first planetary pinion is installed to box house, and then case lid and casing are fixed, adopt seizing type to fix between case lid and casing.Particularly, annular groove is set on casing, boss is set on case lid, boss and annular groove coupling are fixing.
There is following problems at least in technology now: adopt seizing type to fix, can occupy at the axial direction of casing and case lid the space of 3mm-4mm.
The model utility content
The utility model provides a kind of chest assembly, automatic transmission case and automobile, is used for the size of dwindling chest assembly axial direction.
The utility model provides a kind of chest assembly, comprises casing and case lid, wherein:
Offer at least two axial notches on the circumferential direction of described casing end, offer the through hole that runs through described casing thickness direction between two described axial notches;
Be formed with at least two detent projection on the circumferential direction at described case lid edge, be provided with the boss that protrudes from described case lid surface between two described detent projection;
Wherein, described axial notch and described detent projection coupling, described through hole and described boss coupling.
Chest assembly as above, preferably,
The height of described boss is the 1/3-1/2 of described via height.
Chest assembly as above, preferably,
The height of described boss is 0.5mm-1.5mm.
Chest assembly as above, preferably,
Described through hole is square hole, and is provided with rounding.
The utility model also provides a kind of automatic transmission case, comprises planetary pinion, wherein, also comprises the arbitrary chest assembly that provides of the utility model, and described planetary pinion is arranged on the box house of described chest assembly.
The utility model provides again a kind of automobile, wherein, comprises automatic transmission case provided by the utility model.
In technique scheme, axial notch and detent projection all on casing and case lid original structure by being processed to form, can not increase axial notch and the detent projection length in circumferential direction, thereby can be in the space of casing and case lid axial direction saving 3mm-4mm, this is highly significant to the axial dimension that dwindles product.

Embodiment
The housing structure schematic diagram of the chest assembly that Fig. 1 provides for the utility model embodiment, the cover structure schematic diagram of the chest assembly that Fig. 2 provides for the utility model embodiment, the chest modular construction schematic diagram that Fig. 3 provides for the utility model embodiment, Fig. 4 are the local enlarged diagram of Fig. 3.
The utility model embodiment provides a kind of chest assembly, and it is applicable to any needs the chest assembly is set, and need reduce the occasion of chest assembly axial dimension, preferably is applicable to automatic transmission case etc.The chest assembly comprises casing 1 and case lid 2, wherein: offer on the circumferential direction of described casing 1 end between 11, two described axial notches 11 of at least two axial notches and offer the through hole 12 that runs through described casing 1 thickness direction; Be formed with on the circumferential direction at described case lid 2 edges between 21, two described detent projection 21 of at least two detent projection and be provided with the boss 22 that protrudes from described case lid 2 surfaces; Wherein, described axial notch 11 and described detent projection 21 couplings, described through hole 12 and described boss 22 couplings.
Herein, axial notch and detent projection coupling refers to not exist between the two install conflicts, and meets assembly relation, between axial notch and detent projection take transition fit as good.Through hole and boss coupling refers to not exist between the two install conflicts, and meets assembly relation, between through hole and boss take Spielpassung as good.
During installation, the detent projection 21 at case lid 2 edges is inserted in the axial notch 11 of casing 1, boss 22 is placed in through hole 12, then the part in through hole 12 outsides is bent (schematic diagram after press-bending divides referring to the downward bent part in Fig. 4) towards the direction of casing 1 central axis, the part in through hole 12 outsides just can tighten boss 22 like this, so that boss 22 can't spin off from through hole 12, thereby realize the chucking of casing 1 and case lid 2.In above-mentioned chucking mode, axial notch 11 and detent projection 21 all on casing 1 and case lid 2 original structures by being processed to form, can not increase axial notch 11 and detent projection 21 length in circumferential direction, thereby can be in the space of casing 1 and case lid 2 axial directions saving 3mm-4mm, this is highly significant to the axial dimension that dwindles product.
Further, if use the height (equaling the thickness of case lid 2) of through hole 12 as the reference that boss 22 is set, the height of described boss 22 is the 1/3-1/2 of described through hole 12 height.Select the boss 22 of above-mentioned height can play the spacing effect of chucking, and be unlikely to increase the size of chest assembly in radial direction.
Alternatively, for the through hole 12 of any thickness, the height of described boss 22 all can be made as 0.5mm-1.5mm.Select the boss 22 of above-mentioned height also can play the spacing effect of chucking, and be unlikely to increase the size of chest assembly in radial direction.
For ease of processing, described through hole 12 is square hole, and is provided with rounding.
The chest assembly that technique scheme provides, adopt above-mentioned means of fixation, can reduce the increase of the chest assembly that causes because of casing and case lid means of fixation in the axial direction size, and means of fixation is reliable.
The utility model embodiment also provides a kind of automatic transmission case, comprises planetary pinion, wherein, also comprises the chest assembly that the utility model any embodiment provides, and described planetary pinion is arranged on the box house of described chest assembly.
The automatic transmission case that technique scheme provides, have above-mentioned chest assembly, can reduce the increase of the chest assembly that causes because of casing and case lid means of fixation in the axial direction size, and means of fixation is reliable.
The utility model embodiment also provides a kind of automobile, wherein, comprises the automatic transmission case that the utility model any embodiment provides.
The automobile that technique scheme provides, have above-mentioned automatic transmission case, can reduce the increase of the chest assembly that causes because of casing and case lid means of fixation in the axial direction size, and means of fixation is reliable.
It should be noted that finally: above each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to aforementioned each embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment's technological scheme of the utility model.
