Embodiment Construction

[0039] Reference is now made in detail to the description of the embodiments illustrated in the accompanying drawings. While several embodiments have been described using these figures, there is no intent to limit the present disclosure to the embodiments or embodiments disclosed herein. On the contrary, the intention is to cover all alternatives, modifications and equivalents.

[0040] In Figure 1, Figure 7 and Figure 8 A TVD is generally indicated by the reference numeral 100 in FIG. 1 , and includes a hub 200 defining a generally centrally located bore 201 having an inner cylindrical surface 204 and an outer cylindrical surface 202, the inner cylindrical surface 204 accommodating a motor such as an IC motor. Vibrating shaft of the crankshaft, the outer cylindrical surface 202 receives the front engine seal. Hub 200 also includes an outermost radial surface 203 spaced radially outward from bore 201 by plate 205 . Plate 205 may define one or more holes or open windows 2...

Abstract

An elastic body member for a torsional vibration damper and a method of manufacturing the same are disclosed, as well as a torsional vibration damper having the elastic body member. The elastomeric member has a first major surface and an opposing second major surface, the first major surface and the opposing second major surface having opposing sides joining the first major surface and the second major surface, having A midsagittal plane extending parallel to the first and second major surfaces, and a transverse plane perpendicular to the midsagittal plane. The cross-sectional geometry in a plane bisects the midsagittal plane and the transverse plane, the thickness of the elastomeric member varies along a direction in which the midsagittal plane is parallel to the transverse plane, a first thickness at the opposite and a second thickness substantially at said transverse plane, wherein said second thickness is greater than said first thickness.

Description

[0001] related application [0002] This application claims priority to US Provisional Application No. 62 / 104,358, filed January 16, 2015, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to torsional vibration dampers for use in internal combustion powertrains and vehicle drivelines, and more particularly, to a vertical compression molded elastomeric member for use in torsional vibration dampers, elastic The body member has a non-uniform thickness through its axial length with a maximum thickness approximately at its axial center point. Background technique [0004] Torsional Vibration Dampers (TVDs) are used to dampen the torsional vibrations inherent in rotating shafts, including but not limited to crankshafts, drive shafts, support shafts, and half shafts used in automotive and non-automotive applications. [0005] Typically, a TVD consists of three components: (1) a rigid metal support (hub) th...
