Clutch discs for trucks and buses

e076D7Pp5e8

Guaranteed quality has made the brand DT Spare Parts the leading brand in the international Independent Aftermarket for commercial vehicles. The complete range includes all required spare parts for trucks, trailers and buses, including all standard clutch discs.

The DT brand products, made of high quality materials, meet your highest quality requirements and guarantee a long period of use.

The clutch disc is the friction partner between the flywheel and the pressure plate of the clutch cover. It serves to transfer the torque to the gearbox input shaft and so enables a smooth start and quick gear change.

Clutch discs are fitted on both sides with a friction facing, which is either riveted on or, in the case of smaller clutches, glued on. A feature of every
DT Spare Parts clutch disc is the optimized facing resilience system which, depending on the application, enables a troublefree buildup of torque when starting, as well as an ergonomically synchronized pedal force curve.

Through the use of a crown with elastic segments, which is positioned between the carrier plate and the facings, the starting characteristics are additionally improved.

DT-Technic Info

The segments provide axial deflection of the facings, thereby achieving a soft “engagement” of the gears and an even wear out of the facings.

To reduce rotational speed and torque fluctuations of the engine, the clutch discs must also take over a damping function. This reduces noise and wear on the gearbox. The torsional dampers used for this purpose are made of chromium-silicone alloy and ensure trouble-free operation and an optimum service life.

The friction facings used are made of garn, copper or brass wire, which is embedded in a mixture of resin, rubber and filler. They are characterized by low weight and high load capacity. The facings can withstand temperatures of up to 400°C short term.

The friction facings used by the brand
DT Spare Parts are environmentally friendly and contain no heavy metals. They guarantee an optimum balance between performance and service life.

The central and spring retaining plates made of stainless steel are case-hardened and so ensure maximum useful life. To avoid axial run out, each clutch disc is additionally aligned.

In addition to clutch discs, DT Spare Parts also offers all standard clutch covers, release bearings and release forks.
