Patent number: 6406374Abstract: A groove is cut into an end surface of a shaft component to deform the shaft component into irregularities provided on a tubular component, thereby coupling the shaft component with the tubular component to form an outer ring for a constant velocity joint. This type of joint provides an outer ring having a strong coupling force and high coupling precision.

Patent number: 6234907Abstract: Utilizing the quick disconnect driveshaft transmission yoke of the present invention, just a ½ turn of 4 lock nuts on a pair of split lock collars frees a splined slider from its fixed engagement with an external (male) splined output transmission shaft and allows the splined slider to slide rearward within yoke. The splined slider slides rearward within the yoke until the splined slider slides free of the external (male) splined output transmission shaft. The yoke, which has also been freed from the locking engagement of the split lock collars, then drops free and clear of the external (male) splined output transmission shaft. The transmission can then be slid back and the transmission bell housing removed to service the clutch, all without unbolting the driveshaft from either the differential or the yoke. The freeing of a transmission from a driveshaft transmission yoke utilizing the quick disconnect driveshaft transmission yoke of the present invention takes mere seconds.Type: GrantFiled: June 24, 1999Date of Patent: May 22, 2001Assignee: Greg Moser Engineering, Inc.Inventor: Greg A.
