E-Mobility

The automotive industry is shifting towards more sustainable means of propulsion, and electric drives offer a number of advantages: zero local emissions, noise reduction and performance. We have the expertise to assist you in designing the drivetrains of the future.

E-Drives

Interaction between electromagnetic and mechanic forces

Torque ripple

Rolling bearings

Gear box with gear interaction

NVH and gear chatter

E-Motor electric motor E-drive
Rolling bearings
FIRST RB Coupling Element
Rollenlager roller bearing
  • Local elasticity of inner and outer rings

  • Local loads applied upon rings and rolling elements

  • Consideration of pre-tension and clearance effects

  • Lateral loads for each rolling element

  • Thermal expansion of rings

  • Pre-deformed shapes or irregularities

  • Minimum film thickness calculation

Schaeffler Bearinx-MAP interface
BearinX chart Kraftkopplung
  • Point-to-point force coupling method

  • Available for all Schaeffler bearings

  • Look-up table solution based on characteristic diagrams

  • Non-linear behaviour

  • Influences of the DOFs on each other

  • Consideration of bearing clearance

  • Very wide load spectrum

Gears
Getriebe flexible gears
  • Realistic transmission of all forces and torque

  • Local loads applied upon flexible gears

  • Straight or helical gear geometry

  • Inner and outer gears
