Abstract

To address the problem of different engine variants for different inertia, we are proposing a single flywheel assembly design with multiple independent cavities which can be filled by fluid to increase weight of flywheel which in turn increase the inertia.

Title: Multi-Inertia Flywheel

Background/Problem:

Flywheel is a component of engine which connects with transmission components like clutch/damper/torque convertor to transmit power. Inertia of flywheel helps to minimize energy fluctuations by storing energy while in excess and dissipating when required. Inertia also helps to minimize torsional vibrations in crankshaft, hence inertia is the most important parameter for flywheel design. Flywheel assembly consists of ring gear to mesh with starter pinion and machined part. Starter motor pinion rotates flywheel to set engine in motion at the time of ignition. Due to different application requirements of vehicles, the inertia requirement also various which in turn adds numerous flywheel variants. Many Engine factories are facing inventory issues due to many flywheel variables they must handle, and there is a strong demand to reduce this variability.

Proposed Design/Solution:

To address the problem of different variants for different inertia, we are proposing a single flywheel assembly design with multiple independent cavities which can be filled by fluid to increase weight of flywheel which in turn increase the inertia. The proposed flywheel assembly with empty cavities will create X inertia and the flywheel with one cavity filled will create X+A Inertia, similarly multiple cavities can be filled and the similar combinations will help achieving multiple inertia using single design

In an exemplary embodiment, the below flywheel design has two cavities, for which inertia can be varied by filling different cavities with fluid. The fluid can be any oil, water, or other similar means. This new flywheel assembly with two cavities will pro...
