At least there is following problems in technology now: adopt seizing type to fix, can occupy at the axial direction of casing and case lid the space of 3mm-4mm.
Summary of the invention
The invention provides a kind of chest assembly, automatic transmission case and automobile, for dwindling the size of chest assembly axial direction.
The invention provides a kind of chest assembly, comprise casing and case lid, wherein:
In the circumferential direction of described casing end, offer at least two axial notches, between two described axial notches, offer the through hole that runs through described casing thickness direction;
In the circumferential direction at described case lid edge, be formed with at least two detent projection, between two described detent projection, be provided with the boss that protrudes from described case lid surface;
Wherein, described axial notch mates with described detent projection, and described through hole mates with described boss.
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 present invention also provides a kind of automatic transmission case, comprises planetary pinion, wherein, also comprises the arbitrary chest assembly providing of the present invention, and described planetary pinion is arranged on the box house of described chest assembly.
The present invention provides again a kind of automobile, wherein, comprises automatic transmission case provided by the present invention.
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 detent projection in the length of circumferential direction, thereby can be in the space of casing and case lid axial direction saving 3mm-4mm, this is highly significant to dwindling the axial dimension of product.

The cover structure schematic diagram of the chest assembly that Fig. 2 provides for the embodiment of the present invention;
The chest modular construction schematic diagram that Fig. 3 provides for the embodiment of the present invention;
Fig. 4 is the local enlarged diagram of Fig. 3.
Embodiment
The housing structure schematic diagram of the chest assembly that Fig. 1 provides for the embodiment of the present invention, the cover structure schematic diagram of the chest assembly that Fig. 2 provides for the embodiment of the present invention, the chest modular construction schematic diagram that Fig. 3 provides for the embodiment of the present invention, the local enlarged diagram that Fig. 4 is Fig. 3.
The embodiment of the present invention provides a kind of chest assembly, and it is applicable to any chest assembly to be set, and need reduce the occasion of chest assembly axial dimension, is preferably applicable to automatic transmission case etc.Chest assembly comprises casing 1 and case lid 2, wherein: in the circumferential direction of described casing 1 end, offer 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; In the circumferential direction at described case lid 2 edges, be formed with 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 mates with described detent projection 21, and described through hole 12 mates with described boss 22.
Herein, axial notch refers to not exist between the two to install with detent projection coupling and conflicts and meet assembly relation, take transition fit as good between axial notch and detent projection.Through hole and boss coupling refers to not exist between the two to install conflicts, and meets assembly relation, take Spielpassung as good between through hole and boss.
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 to 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 clamp boss 22 like this, so that boss 22 cannot spin off from through hole 12, thereby realize the clamping of casing 1 and case lid 2.In above-mentioned clamping 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 in the length of 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 dwindling the axial dimension of product.
Further, if using the height (equaling the thickness of case lid 2) of through hole 12 as the reference that boss 22 is set, the height of 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 clamping, and be unlikely to increase chest assembly in the size of 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 clamping, and be unlikely to increase chest assembly in the size of 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, adopts above-mentioned means of fixation, can reduce the chest assembly that causes because of casing and case lid means of fixation in the increase of axial direction size, and means of fixation is reliable.
The embodiment of the present invention also provides a kind of automatic transmission case, comprises planetary pinion, wherein also comprises the chest assembly that any embodiment of the present invention provides, and planetary pinion is arranged on the box house of described chest assembly.
The automatic transmission case that technique scheme provides, has above-mentioned chest assembly, can reduce the chest assembly that causes because of casing and case lid means of fixation in the increase of axial direction size, and means of fixation is reliable.
The embodiment of the present invention also provides a kind of automobile, wherein, comprises the automatic transmission case that any embodiment of the present invention provides.
The automobile that technique scheme provides, has above-mentioned automatic transmission case, can reduce the chest assembly that causes because of casing and case lid means of fixation in the increase of axial direction size, and means of fixation is reliable.
Finally it should be noted that: each embodiment, only in order to technological scheme of the present invention to be described, is not intended to limit above; Although the present invention is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or some or all of technical characteristics is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technological scheme.
