| 20120294670 | PIVOT PIN SECURING STRUCTURE - A pivot pin securing structure includes a support seat and a pivot pin. The support seat is formed with a bush section with a pinhole. The bush section is formed with a split in communication with the pinhole, whereby the bush section has elasticity for holding the pivot pin. The bush section has at least one independent spring section. An obliquely extending track section is disposed on at least one side of the spring section. One end of the pivot pin extends into the pinhole. An abutment member is disposed on a circumference of the pivot pin. The abutment section is slidable along the track section with the rotation of the pivot pin in abutment with the spring section to different extents. During the sliding movement, the spring section applies different reaction forces to the abutment section as resistance against and aid force for the rotation of the pivot pin. | 2012-11-22 |
| 20120294671 | METHOD FOR CONNECTING A SHAFT AND A HUB AND SHAFT-HUB ARRANGEMENT - A method for connecting a shaft and a hub, the hub having a first joining portion and a second joining portion for a connection to corresponding joining portions of the shaft. The shaft and the hub are pressed together at contact points in the area of the first joining portions, while the second joining portions are not yet in contact with one another, and a welding current is fed via the contact points of the parts that have been pressed together, so that the contact points fuse. The shaft is pressed into the hub, while the first joining portions are being fused, until substantially a press fit is formed between the second joining portions. | 2012-11-22 |
