Clutch hubs are high strength products that are attached to the clutch plate and used to transmit engine output torque into the transmission. PM has proven to be an ideal and competitive solution for this application due to a combination of net shape capability and excellent material performance.
One Way Clutches
One way clutches (OWC) are a key component of all automatic transmissions. PM’s design freedom combined with dimensional precision, and high performance materials facilitated the development of new OWC systems that are more easily integrated into compact and efficient transmission designs.
Planetary carriers are a key component of automatic transmissions. As the demand increased for more fuel efficient vehicles with transmissions with more forward speeds, planetary carriers became more complex and also began to serve multiple functions.
Shift System Components
Manual, automated manual, and double clutch transmissions rely on a series of components to engage and move the synchronizer system during shifts between gears.
Synchronizer Hubs are the core product for the shifting mechanism in all double clutch and manual transmissions. PM has proven to be the premier solution for this component, and has facilitated improvements in performance while also reducing weight.
Synchronizer Hubs are a key component for the shifting mechanism in all manual and automated manual transmissions. Forged PM has proven to be a competitive and high performance solution for this demanding application for medium and heavy duty trucks.
Torque Converter OWC Races & Assemblies
Automatic transmissions rely on a torque multiplying system that delivers increased torque for initial acceleration. Within the transmission’s torque converter (TC) is a one way clutch (OWC) which locks up to deliver the initial increased torque, and subsequently turns freely when cruising speeds are reached.
Automatic transmissions rely on a torque converter to engage and disengage engine power without the need for a driver-operated clutch. The main part of a torque converter is a fluid turbine which selectively transfers engine power into the transmission.
