Abstract: A chain-belt for engagement with the pulleys of a continuously variable transmission consists of interleaved sets of chain links joined for articulation by a joint which has a rocking action. The joint includes a pair of pins. A small camber is introduced into one or both of the pins to create a spring load between the pins and the links to retain the pins in the chain during handling and assembly. Each chain link includes a pair of spaced apertures adjacent the opposite ends; each aperture has a generally hour-glass shape with the enlarged ends receiving the pins. Also, each chain link has a pair of oppositely disposed tabs adjacent one end with the location of the tabs on the links alternating on adjacent links of each set. In addition the outermost two links of each set of links had a width substantially less than the width of the inner links in that same set.

Abstract: A power transmission chain-belt as disclosed is especially adaptable to transmit power between the pulleys of a pulley transmission, the pulleys of which are each constructed of a pair of flanges. The chain-belt comprises a plurality of sets of interleaved links joined by pivot means, and a set of at least three generally V-shaped or trapezoidal load blocks located between each adjacent pair of pivot means. Each load block has a central opening permitting its assembly with the links, and edge surfaces to drivingly contact the pulley flanges. The central opening of the load blocks has a height greater than the height of the links, so as to define a space therebetween. Resilient means, such as a curved leaf spring, is positioned between each set of links in the space between the chain and the central opening of a set of load blocks to apply a force on the load blocks of each set.

Abstract: The disclosed control system regulates changes of gear ratio in an automatic transmission for a vehicle. A supervisory control arrangement monitors operator input commands through the shift range selector lever, and receives a desired-ratio command either from a shift point computer or from a manual gear shift selector. When the supervisory control arrangement determines that the desired-ratio signal differs from the actual ratio, the monitoring function is interrupted and a shift-initiate command is provided. This command is utilized to assign certain components for use in a shift quality control arrangement, for effecting the controlled ratio change. A torque output signal from the vehicle drive line is used in conjunction with the shift quality control arrangement. After the shift is completed, the previously assigned components are released and the supervisory control arrangement resumes the monitoring of the desired ratio as contrasted to the actual gear ratio.

Abstract: A planetary transmission mechanism comprising two simple planetary gear sets driven by the engine of a vehicle by an input clutch or torque converter and having four friction engaging devices and a one-way engaging device to establish four forward driving ratios and reverse through the transmission. A center output gear is mounted between the input clutch or torque converter and the planetary gear sets. The pair of friction engaging devices comprising clutches associated with the planetary gear set are mounted immediately adjacent the gear input elements which they connect.

Abstract: A control system to change gear ratio in an automatic transmission through friction elements engaged by hydraulic pressure. A closed loop electrical circuit is completed between a transducer, which provides an electrical signal related to the output torque of the transmission, and a pair of control valves, to vary the pressure applied to a friction element by each control valve. A circuit for computing reaction torque is coupled between the transducer and a logic control circuit, which provides logic command signals for controlling operation of components in the closed loop circuit. The system computes an output torque ramp when a downshift is called for by the shift point computer and uses controllers which react oppositely to control engagement of a clutch and brake in response to error signals of torque output compared to a desired ramp to produce a proper shift.

Abstract: An axial piston, variable displacement, wobble plate gas or vapor compressor containing improvements in the capacity control system and in the drive plate and wobble plate mounting arrangements.

Abstract: A rotating annular piston is hydraulically actuated to engage a rotating friction device, such as a clutch or brake, by introducing fluid pressure to an apply chamber for the piston. Disengagement is subsequently effected by exhausting fluid from the chamber, after which a centrifugal pressure head release valve in a wall of the chamber releases any residual entrapped fluid from the chamber in order to prevent undesired false actuation of the rotating piston that may otherwise occur due to centrifugal force acting on the residual fluid. The valve comprises a metallic ball subject to centrifugal force tending to move it radially outward from the piston axis but held in a tapered or conical seat of an exhaust port, thereby blocking the port, by fluid pressure supplied to the apply chamber. In the absence of that fluid pressure, however, the centrifugal force exerted on the ball unseats it and opens the port.
