Filed:

Aug 5, 2004

Appl. No.:

10/912409

Inventors:

Chester Benick - Lafayette IN, US
Paul Jacobson - Lafayette IN, US

International Classification:

F16C 11/00

US Classification:

403122000

Abstract:

An improved ball joint assembly includes a ball stud having a head end portion which is at least partially enclosed by a housing. A contact member has an end portion which engages the head end portion of the ball stud prior to the occurrence of a predetermined amount of wear in the ball joint assembly. The contact member and head end portion of the ball stud are spaced apart upon the occurrence of the predetermined amount of wear in the ball joint assembly. Prior to the occurrence of the predetermined amount of wear in the ball joint assembly, an electrical circuit through the contact member and head end portion of the ball stud is closed. Upon the occurrence of the predetermined amount of wear in the ball joint assembly, the electrical circuit is opened.

Abstract:

A power steering gear assembly which is used to turn steerable vehicle wheels includes a piston disposed in a motor cylinder . A series of rack teeth are connected with the piston . A first tooth space is formed between first and second teeth in the series of rack teeth. The first tooth space has a root portion which includes first and second fillets . The first fillet has a larger radius of curvature than the second fillet . The first and second fillets have centers of curvature which are both disposed between a central axis of the first tooth space and the second rack tooth . The center pinion gear tooth has side surfaces and with intermediate portions and which are offset from continuously curving spatial envelopes and containing tip end portions and and root end portions and of the center pinion gear tooth.

Abstract:

A detent mechanism including a stop pin and a specially configured detent spring provides a recognizable interruption to an operator rotating a control shaft of an engine governor. Increased torque is required to be applied to the shaft to override the detent spring to permit further rotation of the shaft. The detent stop pin is mounted for rotation about the shaft to allow radial positioning of the pin relative to the shaft by a resiliently biased means. The C-shaped detent spring is readily replaceable to provide different tensions for different operating conditions. Fixed stopped means and adjustable stop means limit rotation of the shaft with the detent mechanism operably positioned between the two stops.
