Bolt-on Torsional Damper
Driving comfort and component protection
Key Facts
What can Bolt-on Torsional Damper provide?
Bolt-on torsional dampers from ZF are built on the proven and cost optimized technology of high volume torsional dampers used in clutch disk production. They are integrated into the powertrain behind the engine. Their task is to decouple the torsional vibrations that the engine induces into the powertrain and connected components. This protects the entire powertrain from potentially damaging vibratory torque spikes and raises the level of driving comfort.
Details
Torsional dampers are placed behind the engine as vibrational dampers when the powertrain does not include a separating and starting clutch. The purpose of using a torsional damper is to keep engine torque peaks as well as operational irregularities isolated from the powertrain and connected components.
Thus, every commercial vehicle with a powershift transmission or hydrostatic drive needs a torsional damper that ensures a quiet operation of the vehicle. If the forces operating in the powertrain area were not countered, driving comfort would be noticeably reduced and the powertrain components would also show considerably higher levels of wear or early failure.
A standard solution today for decoupling torsional vibrations in powertrains is to use a bolt-on torsional damper that builds on the proven and cost optimized technology of torsional dampers used in clutch disks.
The torsional damper consists of a set of coil springs, positioned in windows, that allow a rotary movement between the crankshaft and the transmission input shaft. An integrated friction device is used to diminish peak vibratory energy.
By slecting the right torsional damper size and spring set, characteristic curves can be adjusted to meet the individual needs of specific applications. Vibrational decoupling can therefore be adapted in optimum fashion to the vehicle, and ignition-related rotational irregularieties can be reduced.
The torsional damper is integrated into the respective installation space by a simple adjustment of the external bolt-on area and by selecting the corresponding spline profile to match the drive shaft.
The use of steel springs makes the damper absolutely resistant against aging or settling processes. Designed for vehicle lifetime, ZF bolt-on torsional dampers are maintenance free. All components are fully recyclable or can be reused in the ZF remanufacturing process.
