Objective

• To protect drivetrain components
• via
• introduction of a torsionally flexible device
• that
• eliminates and/or minimizes torsional vibrations
  while transmitting the desired torque at the
  desired speed.

User Requirements

• Development tests.
• Performance tests.
• Durability tests.
• Production tests.
• Overhaul.

Advantages -

• The rubber element serves as a Fuse in the
  driveline and thus protects other expensive
  items.
• Higher speeds.
• Custom Application.
• Standard driveshaft Cardan / Constant velocity.

Some examples of custom design

• Coupling-Shaft.
• Soft-high torque.
• Discreet component repair.

8
Some examples of custom design

• Kusel coupling combined with constant velocity
  joint.
• Coupling-shaft.
• Discreet component repair.

9
Some examples of custom design

• Coupling-Shaft with quadruplicate torsional
  flexibility.
• Additive elements to reduce stiffness.

Key Benefits to Customers

• Can be sized and manufactured by AEI in the
  United States.
• Are rebuilt in the United States by AEI leading
  to less down time.
• World wide support through Voith-Kusel AEI.
• Most couplings are custom-built to your
  application.
