Hubcap is mounted on speed changer procapsid, should be able to generally realize assembly oil sealing, bearing positioning, with clutch release bearing phase
Match, the functions such as oil return.Previous input shaft end cap is designed to ironcasting mostly, in order to realize its lightweight, the utility model point
Do not start with from optimization structure and in terms of changing technique two, this structure includes end, sleeve two parts, the two using seperated punching press,
Welding fabrication.End and sleeve are all made of sheet metal forming technology shaping, have both considered the realization of end cap function in structure design, and have also infused
Structure of having anticipated will adapt to Sheet Metal Forming Technology.Tip body is revolving parts, is equipped with bearing location hole, seal mounting hole and oil groove,
End outer is equipped with the bolt unthreaded hole with shell connection.In structure design, the two ranks of bearing location hole, seal mounting hole
Tread is designed to right angle cascaded surface, and ladder fillet is smaller；Transition face between this two cascaded surfaces is designed to tiltedly without critical function
Face is in favor of punching press, and ladder fillet is larger；It is designed to inclined-plane at oil groove, be not only conducive to oil return but also is conducive to punching press.Sleeve is tubing
Part, external cylindrical surface part and release bearing cooperate, and central through hole is the different two-part aperture structure of internal diameter, internal diameter it is big one
Section cooperates with end, and another section of internal diameter reduces to improve the rigidity of sleeve.
