Components for Transmissions

LuK CVT - Components for Continuously Variable Transmissions

Continuously Variable Transmissions (CVT) can be designed on the basis of a number of different principles. Chain-driven transmissions have shown itself to be suitable for use in cars. In the past it was primarily used for vehicles in the lower performance range. LuK CVT components (pulleys, link-plate chain and hydraulics) now represent the first high-performance CVT working on the chain drive principle that can be used for powerful engines with a torque range of up to 400 Nm. The transmission ratio between the engine and the drive wheels changes continuously together with a change in width of the wedge-shaped pulley. An infinite number of drive ratios allow the engine to always run under optimum operating conditions.

The most important benefits for the customers:

  • Excellent driving comfort thanks to smooth transmission changes, i.e. no shifting between different gears.
  • Low fuel consumption due to large gear ratio.
  • Excellent driving dynamics as there are no interruptions to tractive power.
  • Compact design
