Embodiment
Refer to Fig. 1 and Fig. 2, in order to understand technological scheme of the present invention better, below by embodiment particularly, and be described in detail by reference to the accompanying drawings.
Refer to Fig. 1, automatic speed variator casing of the present invention comprises interior hub 1 and outer hub 2 (not showing in Fig. 1), arranges the first annular face of weld 11 bottom described interior hub 1.In the present embodiment, along six welding boss 3 of the uniform equal altitudes of described first annular face of weld 11.Described welding boss 3 is processed by impact briquetting.
Refer to Fig. 2 a and Fig. 2 b, the table top of described welding boss 3 welds with the second annular welds junction at described outer hub 2 top, obtains automatic speed variator casing of the present invention.In the present embodiment, the welding procedure adopted is projection welding process.This is because be the requirement in order to meet projection welding process along one of the object of six welding boss 3 of the uniform equal altitudes of described first annular face of weld 11, to reduce the consumption of the energy in welding.But the table top of described welding boss 3 welds with described second annular welds junction and is not limited to a kind of welding procedure of projection welding process, and other welding procedure, as spot-welding technology, percussion welding technique etc. are also fine.
Refer to Fig. 3, weld owing to only having between the table top of six described welding boss 3 with the second annular welds junction at described outer hub 2 top, so define six lubrication gaps 4 in the side correspondence of automatic speed variator casing, described lubrication gap 4 is between adjacent two welding boss 3, it is inner that described lubrication gap 4 can flow into automatic speed variator casing for lubricant oil, lubricates clutch assembly.It is inner that the object of such design is to make lubricant oil flow into automatic speed variator casing by described lubrication gap 4, lubricates, thus improve the working life of clutch assembly, ensure traffic safety to clutch assembly.
In addition on the one hand, only have between the table top of six described welding boss 3 with the second annular welds junction at described outer hub 2 top and weld, bonding area between described interior hub 1 and described outer hub 2 reduces, reduce the power consumption needed for welding and labor intensity, simultaneously, the flatness of the table top controlling described welding boss 3 is only needed when welding, and do not need to control whole described first annular face of weld 11, can realize the control of welding quality, therefore the welding quality of automatic speed variator casing more easily controls.
Have must be pointed out at 2: first, the second annular welds junction at described outer hub 2 top arranges described welding boss, the table top of described welding boss welds with the first annular face of weld 11 bottom described interior hub 1, also can obtain automatic speed variator casing of the present invention.
The second, the quantity along the welding boss 3 of described first annular face of weld 11 or the uniform equal altitudes of described second annular welds junction is not limited to six.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
