Abstract
The invention discloses a motorcycle clutch outer cover structure capable or preventing nitridation deformation. The motorcycle clutch outer cover structure comprises an outer left cover, an outer right cover and a splined hub, wherein the outer right cover is connected with the outer left cover in a welded manner; the splined hub is connected with inner holes of the outer left cover and the outer right cover in the welded manner; an air outlet is formed in a bottom cover plate of the outer left cover or the outer right cover. According to the motorcycle clutch outer cover structure capable or preventing nitridation deformation, after being welded, contact surfaces of the bottom cover plates of the outer left cover and the outer right cover are sealed by weld joints, so that a sealed space is formed; in the nitridation process, the air in the sealed space is heated to expand; as the air outlet is formed in the bottom cover plate of the outer right cover, the expanded air can be discharged out from the air outlet, so that the problem of the deformation of the outer covers caused by the air expansion is solved.
Description
Technical field
The present invention relates to a kind of clutch, more particularly to a kind of outer housing of clutch of motorcycle.
Background technology
Heat treatment is the important processing technique of improve product quality, and the material after heat treatment can improve product hard
Degree, intensity, extend product service life.
Such as the outer housing of clutch of motorcycle, which frequently can be contacted with brake pad in the course of the work, it is therefore desirable to its tool
There are higher hardness and anti-wear performance, therefore need in a manufacturing process nitrogen treatment to be carried out to outer housing.But due to outer housing nitrogen
Changing to process is being carried out in the environment of sealing, and air expanded by heating in nitridation process causes outer housing to deform, and affects the property of product
Energy.
The content of the invention
In view of this, it is an object of the invention to provide a kind of prevent from nitrogenizing the Autobike clutch outer cover structure for deforming,
To solve the problems, such as that nitridation deformation easily occurs in existing Autobike clutch outer cover.
The present invention can prevent the Autobike clutch outer cover structure for nitrogenizing deformation, including left outside cover and left outside cover welding from connecting
The cover of the right outer housing for connecing and the spline housing being connected with the inner hole welding of rapid cooling of left outside cover and right outer housing, the left outside cover or right outer housing
Hole of cooling down is provided with base plate.
Further, it is provided with an annular on the cover plate outer surface of the left outside cover or right outer housing to cool down groove.
Beneficial effects of the present invention：
The present invention can prevent the Autobike clutch outer cover structure for nitrogenizing deformation, the cover of its left outside cover and right outer housing after welding
Closing space is sealed to by weld seam between base plate contact surface, in nitridation process, the air heats expansion in this closing space,
Due to being provided with hole of cooling down on the cover base plate of right outer housing so that expanded air can be by hole discharge of cooling down, so as to eliminate air
Outer housing problem on deformation caused by expansion.
Description of the drawings
Fig. 1 is the structural representation of the Autobike clutch outer cover structure that the present invention can prevent from nitrogenizing deformation.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As illustrated, the present embodiment can prevent nitrogenize deformation Autobike clutch outer cover structure, including it is left outside cover 1, and
Right outer housing 2 that left outside cover 1 is welded to connect, and the spline housing 3 that be connected of inner hole welding of rapid cooling with left outside cover and right outer housing, it is described it is right outward
Hole 4 of cooling down is provided with the cover base plate of cover, hole 4 of cooling down described in being embodied as certainly can also be provided at the cover base plate of left outside cover
On.
Clutch housing after welding, is sealed to envelope by weld seam between its left outside cover 1 and the cover base plate contact surface of right outer housing 2
Space is closed, in nitridation process, the air heats expansion in this closing space disappears due to being provided with the cover base plate of right outer housing
Pore 4 so that expanded air can be discharged by hole 4 of cooling down, so as to eliminate outer housing problem on deformation caused by air expansion.
As the improvement to the present embodiment, an annular is provided with the cover plate outer surface of the left outside cover 1 and is cooled down groove
5, certainly annular groove of cooling down may also be arranged on the cover plate outer surface of right outer housing；It is due in nitridation process, left outside
Partial air be there may exist between cover 1 and the cover base plate contact surface of right outer housing 2 to discharge from hole 4 of cooling down completely, this improvement
Groove 5 cool down by annular can be to this portion gas offer receiving space, so as to further eliminate the outer housing in nitridation process
Problem on deformation.
Finally illustrate, above example is only unrestricted to illustrate technical scheme, although with reference to compared with
Good embodiment has been described in detail to the present invention, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent, and without deviating from the objective and scope of technical solution of the present invention, which all should be covered at this
In the middle of the right of invention.
