Industry Solutions
Demands on the automotive industry:
Owing to the characteristics of the speed-torque curve in the electric motor, it is possible to adapt the product range to suit the tractive power requirement curve in vehicles using fewer gears than is the case with the combustion engine. But industry professionals all agree that gear transmissions will continue to be indispensable, even in an electrified powertrain. This is necessary to meet requirements for driving comfort, efficiency and vehicle costs.
Klingelnberg solution:
With GearEngine® and its Closed Loop approach, Klingelnberg has developed a exceptional solution for the process chain in cylindrical gear manufacturing. Owing to the quality-determining influence of hard finishing, the networking of Speed Viper with the Klingelnberg P series is a crucial step in ensuring the quality of the production process.
