Abstract
The utility model discloses a kind of Autobike clutch outer cover structure preventing nitrogenize to be out of shape, the right outside cover comprise left outside cover, being welded to connect with left outside cover and the spline housing be connected with the inner hole welding of rapid cooling of left outside cover and right outside cover, the cover base plate of described left outside cover or right outside cover is provided with hole of cooling down.The Autobike clutch outer cover structure that the utility model can prevent nitrogenize to be out of shape, enclosure space is sealed to by weld seam between its left outside cover and cover base plate contact surface of right outside cover after welding, in nitridation process, air heats in this enclosure space expands, due to the cover base plate of right outside cover being provided with hole of cooling down, expanded air is discharged by hole of cooling down, thus eliminates air and to expand the outer cover problem on deformation caused.
Description
Technical field
The utility model relates to a kind of clutch, particularly a kind of outer cover of clutch of motorcycle.
Background technology
Heat treatment is the important processing technology of improving the quality of products, and the material after Overheating Treatment, can improve product hardness, intensity, extends product service life.
As the outer cover of clutch of motorcycle, it can contact with brake pad in the course of the work frequently, therefore needs it to have higher hardness and anti-wear performance, therefore needs in a manufacturing process to carry out nitrogen treatment to outer cover.But because outer cover nitrogen treatment carries out under the environment in sealing, air expanded by heating in nitridation process, causes outer cover to be out of shape, and affects the performance of product.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of Autobike clutch outer cover structure preventing nitrogenize to be out of shape, and easily occurs to solve existing Autobike clutch outer cover the problem that nitrogenize is out of shape.
The Autobike clutch outer cover structure that the utility model can prevent nitrogenize to be out of shape, the right outside cover comprise left outside cover, being welded to connect with left outside cover and the spline housing be connected with the inner hole welding of rapid cooling of left outside cover and right outside cover, the cover base plate of described left outside cover or right outside cover is provided with hole of cooling down.
Further, the cover plate outer surface of described left outside cover or right outside cover is provided with an annular to cool down groove.
The beneficial effects of the utility model:
The Autobike clutch outer cover structure that the utility model can prevent nitrogenize to be out of shape, enclosure space is sealed to by weld seam between its left outside cover and cover base plate contact surface of right outside cover after welding, in nitridation process, air heats in this enclosure space expands, due to the cover base plate of right outside cover being provided with hole of cooling down, expanded air is discharged by hole of cooling down, thus eliminates air and to expand the outer cover problem on deformation caused.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Autobike clutch outer cover structure that the utility model can prevent nitrogenize to be out of shape.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the Autobike clutch outer cover structure that the present embodiment can prevent nitrogenize to be out of shape, the right outside cover 2 comprise left outside cover 1, being welded to connect with left outside cover 1 and the spline housing 3 be connected with the inner hole welding of rapid cooling of left outside cover and right outside cover, the cover base plate of described right outside cover is provided with hole 4 of cooling down, and hole 4 of certainly cooling down described in concrete enforcement also can be arranged on the cover base plate of left outside cover.
Clutch housing after welding, enclosure space is sealed to by weld seam between its left outside cover 1 and cover base plate contact surface of right outside cover 2, in nitridation process, air heats in this enclosure space expands, due to the cover base plate of right outside cover being provided with hole 4 of cooling down, expanded air is discharged by hole 4 of cooling down, thus eliminates air and to expand the outer cover problem on deformation caused.
As the improvement to the present embodiment, the cover plate outer surface of described left outside cover 1 is provided with an annular and cools down groove 5, certain described annular groove of cooling down also can be arranged on the cover plate outer surface of right outside cover; Due in nitridation process, likely there is partial air between left outside cover 1 and the cover base plate contact surface of right outside cover 2 can not discharge from hole 4 of cooling down completely, this improvement can provide spatial accommodation to this part gas by annular groove 5 of cooling down, thus can eliminate the outer cover problem on deformation in nitridation process further.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
