Alpha is the next generation in tensioner technology specifically optimized for hybrid drives. It incorporates optimal response to high torque fast-switching between motoring and generating modes without excessive belt tension.
Our original hybrid system tensioner designed to be mounted directly to the electrical motor unit (MGU).
Litens’ eStrut is the industry’s first accessory drive tensioner that can be controlled electronically. Ideal for hybrids where high belt tension can be selectively employed to transmit high torque only when needed. This control allows one to optimize the balance between high power transmission and reduced friction loss.
Mounted in place of a standard crankshaft pulley, the BASFiltr™ (Belt- Alternator-Starter) smooths the engine firing pulses transmitted through the belt which allows the electric motor unit to transmit higher torque to the engine without slippage or damage.
Where it is not feasible to use a BASFiltr™, the DRIVFiltr™ gives engine designers the option to mount the power smoothing device to the electrical motor unit to achieve similar benefits in fuel economy and NVH.
