Patent ID: 7568540

Claim:
A supercharged vehicle comprising: a chassis; an engine; and an air induction system operable to deliver compressed induction fluid to the engine and including a supercharger and a supercharger drive, said supercharger drive being drivingly connected relative to said engine and operable to supply power to said supercharger, said supercharger drive including first and second rotatable drive members that cooperate to transfer driving power from the engine to the supercharger, said supercharger drive further including a breakaway coupler assembly selectively interconnecting said drive members so that the members are normally drivingly connected by the coupler assembly under a variable torsion force, said coupler assembly being configured to drivingly disconnect the members and enable the members to rotate independently of one another for at least one revolution when said torsion force exceeds a predetermined value, said breakaway coupler assembly including a disc, said first and second drive members being gears and each presenting a common rotational axis with said disc, said coupler assembly further including a first pin projecting from said first drive gear into said disc and a second pin projecting from said second drive gear into said disc.
