Freewheeling Retarder from Scania Reduces Fuel Consumption
Scania, one of the world’s leading manufacturers of trucks and buses for heavy transport applications, has introduced a new hydraulic retarder which is engineered to provide greater comfort and deliver savings by reducing the need for normal brake system maintenance.
The new version, R4100D, automatically disengages and enters a freewheeling mode when not active.
This reduces drag losses because both vaned wheels that provide braking power when rotating in oil are disengaged.
Actual fuel savings will vary depending on road conditions, but an average of a half percent reduction.
The driver doesn’t have to do anything.
When braking power is needed, the freewheeling stops and the engagement takes place smoothly and immediately using a type of synchronization that is similar to that in Scania gearboxes.
