Vibration-Damping Jaw Clutch Hub with Metal Core and Plastic Sheath

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention is a specialized clutch hub designed for jaw clutches used in vibration-damping power transmission between a driving shaft and a driven shaft. It consists of a metal part with multiple driving jaws, partially enclosed by a thermoplastic sheath, and is made from a non-ferrous metal alloy of zinc, aluminum, and magnesium. Additionally, there is a jaw clutch utilizing a star-shaped elastomeric ring gear.

Use CasesContent extracted from patent full text and abstract with AI.

• Automotive powertrains requiring vibration-damping during torque transfer
• Industrial machinery where smooth and reliable engagement between driving and driven shafts is critical
• Hybrid vehicles that need efficient power transmission with reduced mechanical noise and wear
• Mechanical systems subject to frequent starts and stops for improved longevity

BenefitsContent extracted from patent full text and abstract with AI.

• Improved vibration damping for smoother power transmission
• Reduced wear and tear due to the combination of metal and plastic components
• Lightweight yet durable due to the use of non-ferrous metal alloys
• Enhanced longevity of the clutch hub and connected components
• Potentially lower noise during operation
• Increased design flexibility from the use of thermoplastic sheaths

Patent Abstract

The clutch hub has a metal part (2) provided with a component comprising multiple entrainment jaws (9). Another component of the metal part is provided as a plastic sheath (11) that is made from a thermoplastic, where the plastic sheath is used for partially enclosing the former component. The metal part is made from a non-ferrous metal, where the non-ferrous metal is an alloy formed from zinc, aluminum and magnesium. An independent claim is also included for a jaw clutch with a star-shaped elastomeric ring gear.
