A manufacturer of racing engines needed to connect the
individual throttle valves together on an IndyCar race engine. The throttle valves
regulate the flow of air into each combustion chamber on the fuel injected engine. This is
then connected to the throttle linkage, which is controlled by the driver's foot pedal.
The flexible coupling is used to compensate for normal misalignments caused by
manufacturing tolerances and distortion of the manifold containing all the throttle bores.
Another concern was the extremely high vibration levels from engines running at 13,000
RPM, and forces caused by the high engine torque.
The most difficult problem the flexible coupling had to overcome was the vibration forces and twisting caused by the high torque of the engine, in addition to the normal tolerances and misalignments in the manufacture of the manifolds. These units have been well tested and proven to accomplish everything the customer wanted in a flexible shaft coupling. It has been very successful in actual racing.
