Abstract: An engine accessory belt drive includes a self-aligning pulley assembly including a relatively stationary outer assembly and a universally pivotable inner assembly supported by the outer assembly and able to be locked in position by tightening of a fastener. During alignment of the self-aligning pulley with the belt, the fastener is maintained in the loose position, allowing limited universal pivoting of the rotational axis of the pulley as a result of belt tension forces which act to align the pulley. After the pulley is aligned, the fastener is tightened to fix the rotational axis of the pulley and the inner assembly in the aligned position of the pulley. Features of the inner and outer assemblies of the pulley assembly are also described.

Abstract: A replacement overdrive piston retainer for an automatic transmission that rotationally engages and interconnects the reverse drum within the transmission housing to the overdrive clutch assembly, which is mounted on the exterior of the housing is disclosed. An integral hub diameter formed on the present piston retainer provides a plurality of lubrication sites positioned at predetermined angular locations to deliver automatic transmission fluid to the interface of the hub diameter and the reverse drum in timed relation to the rotation of the reverse drum in an amount sufficient to maintain clearance and to minimize premature wear and galling at the interface of the components. In addition, lubrication reservoirs have been integrally formed within the hub diameter in fluid communication with the lubrication sites to improve the flow of automatic transmission fluid through the piston retainer to the mating interface of the hub diameter and the reverse drum.

Abstract: In a V-belt type transmission having a V-belt entrained on a pulley, the pulley includes a fixed pulley half fixed to an end portion of a crankshaft and a movable pulley half supported on the crankshaft but axially slidable in opposition to the fixed pulley half. The fixed pulley half is secured with a bolt that is threaded and engaged with a female screw formed inside an end portion of the crankshaft. The V-belt type transmission is capable of securely clamping a fixed pulley half and is capable of preventing the entry of dust and water into a fixed pulley half threaded portion formed in an end portion of the crankshaft. This arrangement protects against the formation of rust and corrosion.

Abstract: A torque transmission device for providing steplessly variable torque conversion. The torque transmission device has a set of unidirectionally-rotatable, slotted levers radiating from a first axis, capable of engaging a torque output ring which is also rotatable on the first axis. An abaxial ring, which has studs that operate in the slots of the levers, is rotatable on a parallel second axis which can orbit the first axis. Torque input induces the second axis to orbit the first, and the force of orbital motion bears, through the abaxial ring, on at least one lever in a direction opposite its rotatable direction, holding it fixed, and also bears on at least one other lever in a direction that coincides with its rotatable direction, causing it to rotate. The fastest-rotating lever engages and drives the torque output ring. Varying the distance between the first and second axes varies the torque conversion ratio.

Abstract: In a chain tensioner having a plunger biased to protrude from a housing by a spring, a pair of wedge-shaped cams are received in tapered recesses in the end of the housing, cooperate with racks formed on opposite sides of the plunger, and are urged against oblique seats formed by the tapered recesses by a biasing spring. The cams and racks produce a ratcheting action maintaining chain tension by preventing retracting movement of the plunger. The cams and racks disperse the load imparted to the plunger by the chain, and reduce localized wear, allowing the housing to be made from a light weight material such as aluminum. Accuracy requirements associated with conventional pawl-type ratcheting tensioners are avoided.
