Diesel Flex Plate Development Process

1993-11-01
932981
Basic procedures are described for the design and development of flexible drive plates that couple automatic transmissions to engines. An innovative combination of analysis and test techniques were employed during the development of a drive plate for a turbocharged diesel truck engine when premature failures occurred. FEA (finite element analysis) was expanded from use as a preliminary design tool to the prediction of high stress conditions and the loading that caused them. A laboratory test was developed to rapidly assess drive plate design changes based on these FEA predictions.

New Concept Modular Manual Transmission Clutch and Flywheel Assembly

1992-09-01

Most United States vehicle assembly plants produce significantly more automatic transmission equipped vehicles than manual transmission vehicles. Assembling these two vehicles on a common production line can create complexity problems. This paper describes the design and development of a pre-assembled manual transmission clutch and flywheel modular assembly which reduces most of these problems. This assembly is used on the 1993 model year mini-van with a 2.5L four cylinder engine. This modular clutch system utilizes the same starter ring gear carrier (driveplate) used on automatic transmission equipped vehicles. It pilots into the crankshaft similar to the automatic transmission torque converter. It is balanced as an assembly which results in a lower system imbalance. A significant system piece cost saving, in comparison with today's competitive market, was achieved.

Chrysler Torque Flite Transmission

1958-01-01

THIS paper describes the Chrysler TorqueFlite transmission, a 3-speed unit with torque converter. The discussion includes details of the push-button controls of the automatic transmission, operation of the transmission and hydraulic controls, power transmission through the gearbox, and design of several of the components. The authors think that the TorqueFlite offers to a greater degree the advantages of automatic transmission: ease of operation and maximum power over a wide range of car speeds.

The Chrysler PowerFlite Transmission

1954-01-01

THE design and construction of the PowerFlite automatic transmission are described by the authors. It is of the torque converter type, some models being water-cooled, while others are direct air cooled. Details of the hydraulic controls are explained, including the one-piece shift valve and the shuttle valve for controlling closed-throttle shifts. It is claimed that this transmission has relative simplicity, light weight, and smoothness of operation.

Chrysler's New Front Wheel Drive Automatic Transmission

1979-02-01
790018
A new three-speed automatic transmission has been designed, developed and is being produced in the U.S. by the Chrysler Corporation for its new family of front wheel drive vehicles. The transmission was designed around the Chrysler-proven TorqueFlite concept. The features of the new transmission include a “folded” construction for installation in a transverse power train. The case is a one-piece aluminum die cast housing and contains the final drive and differential unit. This paper describes the design and development of this new automatic transmission.
