Patent number: 6454656Abstract: A unique structure for connecting the cross member of a universal joint to two yokes includes at least a pair of wing bearings bolted to one of the yokes. Preferably, the other yoke utilizes full circular bores to receive the other two shafts of the cross member. The wing bearings include structure which ensures a secure connection to the yoke. In particular, a locator finger extends radially inwardly from the yoke and over the wing bearing and shaft. In this way, the distance between a reaction plane between the yoke and wing bearing and the centerline of the shaft within the wing bearing is reduced. This reduces a force moment on the shaft. In other features of this invention, the use of the full circular bore for one of the yokes allows the universal joint manufacturer to fully assemble the first yoke to the cross member, and ship that assembled yoke and cross member to the vehicle manufacturer.Type: GrantFiled: October 2, 2001Date of Patent: September 24, 2002Assignee: Meritor Heavy Vehicle Technology, LLCInventors: Ronald N.

Patent number: 5868626Abstract: An improved yoke for use in a universal joint is described having a plurality of axially-extending grooves formed therein. The grooves are formed in the outer cylindrical surface of the sleeve portion of a yoke connected to an end of a vehicle driveshaft so as to permit access of a nut runner or other suitable tool for tightening the fasteners used for securing the retaining device to the other yoke used in the universal joint. The number of grooves provided is dependent on the number of fasteners used to secure the retaining device to the other yoke used in the universal joint. The length, width, and depth of the grooves may vary depending on a number of factors including the clearances between the yokes and other adjacent vehicle components and the type of tool required to secure the retaining device to the yoke. The axially-extending grooves are formed in the yoke such that a fastening tool will be aligned with the retaining device fasteners when the tool is positioned in a groove.Type: GrantFiled: April 30, 1997Date of Patent: February 9, 1999Assignee: Dana CorporationInventor: Timothy M.
