Abstract: Parallel-axis gear differentials include a housing rotatable about a common axis of a pair of output shafts, and a planetary gearset mounted in the housing for interconnecting the output shafts. The gearset includes a pair of side gears positioned within the housing and fixed for rotation with the output shafts, and two or more pairs of meshed pinions journally mounted in gear pockets formed in the housing, with each pinion having a gear segment meshed with a gear segment of the other pinion and with one of the side gears. An anti-tipping mechanism includes brake shoes that are journalled on stub shaft segments of the pinions. Each brake shoe has a first support surface which mates with the outer diameter surface of a corresponding side gear, a second support surface which mates with the outer diameter surface of the gear segment on the adjacent meshed pinion, and a third support surface which mates with the wall surface of the gear pocket.

Abstract: A quick connector coupling for a fluid line includes a hollow female connector body which receives a tubular male member with a raised annular upset. A retainer is demountably coupled to the connector body. The retainer includes two spaced beams which extend through slots in the connector body from a cross member postioned outside of the connector body. The beams are positioned between the upset and an end of the connector body, and have a relaxed spacing less than the upset diameter such that the male member is secured in the connector body. A release protrusion projects from each retainer beam between the cross member and the connector body. The release protrusions have cam surfaces cooperable with an external surface of the connector body to spread the retainer beams apart when the cross member is pressed toward the connector body.

Abstract: A connector for attaching an exhaust gas recirculation tube to an intake manifold of an internal combustion engine. A thermal isolator surrounds an end of the tube and includes a sleeve contacting the tube and merging with a cylindrical body portion which is spaced from the tube. An upset bead is formed in the body portion. The tube and thermal isolator are inserted into a flange surrounding an opening formed in the intake manifold. A retainer is inserted into the flange and rotated such that latching devices on the retainer engage hooks on the flange to prevent removal of the retainer from the flange. The retainer also has ribs for supporting the body portion of the thermal isolator. The retainer is sized to engage the bead of the thermal isolator to prevent removal of the thermal isolator and tube from the flange. The flange and thermal isolator are sealed against fluid leakage.
