Patent number: 4942652Abstract: A method for making constant velocity joint cages involving a minimalization of offal, scrap, rework, production time and production costs. A sheet of flat metal stock is die-cut stamped or cut by laser into a circularly shaped multi-limbed member having a central circular aperture therein and truncated limb radials extending therefrom that end in a predetermined angle. The multi-limbed member is then pressed into a spherical shape, forming a half-cage member. This process is repeated to make a second half-cage member. The two half-cage members are then placed together with their radials aligned. The aligned radials form legs which thereby define windows on the cage. The half-cage members are then rotated relative to each other with the angle on each radial acting as a ramp that causes the window width to lengthen or shorten in response to rotation in a particular direction. In this way, the window width may be precisely set to specification.Type: GrantFiled: March 13, 1989Date of Patent: July 24, 1990Assignee: GKN Automotive, Inc.Inventors: Daniel W.

Patent number: 4869129Abstract: A limited slip differential employs a combined differential gear mechanism with a viscous fluid coupling. A gear connection to a first portion of a drive train causes a limited slip differential housing to rotate. A bevel gear is rotatably attached in fixed position to the interior of the housing. Differential gear sleeves are rotatably attached to either end of the housing. Each of the differential gear sleeves has a differential gear which gearingly meshes with the bevel gear and receives an axle from a second and third portion of the drive train, respectively. One of the differential gear sleeves is translatably movable relative to the housing. A fluid chamber within the housing contains a high viscosity fluid as well as a set of annular plates attached to the housing and a set of annular plates attached to the differential gear sleeve which is translatably movable. The sets of annular plates are in interleaved relation to each other.Type: GrantFiled: December 22, 1987Date of Patent: September 26, 1989Assignee: GKN Automotive, Inc.Inventor: Daniel W. Hazebrook

Patent number: 4573947Abstract: A constant velocity torque transmitting universal joint, utilizing spherical ball members arranged in a longitudinal groove of an inner joint member, is adapted to connect to a shaft and a longitudinal groove of an outer joint member. The outer joint member is connected to a second shaft so that the outer joint member may be displaced in an axial direction relative to the inner joint member. Therefore, the inner joint member may be displaced in an axial direction relative to the cage restraining member holding the spherical ball members in their mutually opposed grooves of their respective joint members. The cage restraining member permits the spherical ball members to roll in their respective grooves for a short distance prior to skidding to reduce the overall resistance to axial movement effort prior to skidding as a result of the friction torque relationship of the joint.Type: GrantFiled: September 4, 1984Date of Patent: March 4, 1986Assignee: GKN Automotive Components, Inc.Inventors: Daniel W.
