Technical description

A variable valvetrain system increases efficiency of the internal combustion engine in wide map ranges. The axially displaceable cam packs are actuated by an electric actuator and switch reliably within one motor revolution.

Customer benefits / unique selling propositions

• Mechanical stroke changeover of the valves by override control

• Individual cylinder control by electromechanical actuator

• Application-appropriate material use and reduced required materials due to assembled design

• Secure cam positioning in end position by locking

Technical description

The camshaft controls the charge change in the combustion engine. By implementing this as a multi-part component, it is possible to use the optimum material in the right place and reduce the weight. All components connected securely through proven technology.

Customer benefits / unique selling propositions

• Reduced weight compared to solid material

• Cost advantage through mature process technology

• Mounting of needle bearings possible

• Flexible design thanks to modular construction

• Use of material suitable for application and reduced need for materials  through built execution

• Secure connection of the components with the fundamental shaft

Technical description

The rotor shaft is used to hold the laminated core and ensures torque transmission from the electromagnetic area to the mechanical area. The built rotor shaft enables the integration of further functions inside the shaft (e.g. cooling). Another advantage is the reduction of the weight reduction.

Customer benefits / unique selling propositions

• Stress-related combination of different materials on one shaft

• Integration of functions possible by using the available space in the rotor shaft

• Less machining effort due to design close to finished size

• 100% quality data recording for each connection
