Embodiment Construction

[0024] In the drawings, the same reference numerals are used to describe the same components. In the following description, various operating parameters and components are described for differently constructed embodiments. These specific parameters and components are included in this specification as examples and not meant to be limiting.

[0025] In general, the present invention is a flexible driving disc composed of a driving disc and a driven disc connected by springs and riveted to each other. This spring arrangement forms a shock absorber.

[0026] More specifically, refer to Figures 1 to 4 , show end and perspective views, respectively, of the flexible drive disk assembly, generally illustrated at 10 . The flexible drive plate assembly 10 includes a ring gear 12 mounted on a driven plate 14 for selective engagement with a starter motor (not shown).

[0027] Inside the flexible driving disc assembly 10 is a damping assembly 16 including a first friction disc 18 , a ...

Abstract

A flexible driving plate having a torsional damper incorporating springs that are positioned in pockets that are non-linear relative to the direction of rotation of the crankshaft is disclosed. The torsional damper connects an engine crankshaft and a transmission input member wherein the crankshaft has a rotational direction. The damper comprises a drive plate connected to the crankshaft, a driven plate connected to the input member, a plurality of springs, and a like number of spring pockets in which the springs are fitted formed in both the drive plate and the driven plate. A plastic spacer is provided in each spring. The axis of each pocket is at an angle other than 90° relative to the angle of rotational direction of the crankshaft.

Description

technical field [0001] The present invention relates generally to flexible drive discs for vehicle transmissions. More specifically, the invention relates to a compliant drive plate added to a torsional damper to provide additional damping of engine-generated torque and to isolate torsional vibrations from the driveline ahead of the rear damper. Background technique [0002] The powertrain of most modern automobiles today includes an automatic transmission as a standard part of the vehicle's driveline. A typical automatic transmission incorporates a flexible drive plate (or flex plate). A flexible drive disc operates differently than a flywheel in a manual transmission that provides a mechanical connection between the transmission and the engine. [0003] The flexible drive disc is usually mechanically secured by bolts to the output end of the engine crankshaft. The output of the flexible drive plate is itself connected to a torque converter which itself includes an inter...
