Universal Joint
F100 - F150 - F250 - F350 - Bronco & GMC
A double Cardan universal joint has a centering means in which the ball seat is biased into engagement with the centering ball with a constant spring force.
Specifically, a movable ball seat is biased by a spring which reacts against a member which slides on the longitudinal axis of the yoke carrying the ball seat and which pivots on the yoke carrying the fixed centering ball about the centering ball center.
An improved sealing arrangement is also disclosed. Specifically, a synthetic rubber lip seal seals against the major diameter portion of an outer spherical surface on a sleeve carrying the ball seat.
Such an arrangement removes the synthetic rubber lip seal from the heat generated by the centering ball and ball seat and minimizes the flexure of the lip seal during joint operation.
