According to foreign media reports, ZFS's Saks introduced a multi-stage Torsional dampers, which are usually mounted on the rear side of the engine and used as vibration dampers. Prevents engine torque from peaking, ensuring smooth operation of the powertrain and coupling unit.
The torsional vibration dampers consist of pairs of coil springs, which are arranged opposite each other and have different sizes. The lengths, material thicknesses, and number of coils also vary. In addition to traditional coil springs It is also possible to use double coil springs. With multi-stage torsional vibration dampers, the clearance of the spring aperture is relatively large.
Before the equipment is removed or installed, the spring of the torsional vibration damper in the constant power clutch is loosely located in the spring aperture in the backing plate.
The corresponding damping springs can be continuously engaged and present multiple levels, depending on the angle of rotation of the torsional vibration damper. The torsional vibration damper of the PTO clutches is designed to effectively reduce noise and vibration. At the same time with resilience.
The rapid delivery of spare parts is a top priority, especially in the commercial vehicle segment market, as the breakdown of vehicles means that revenue is impaired. After the ZF Aftermarket can be independent The market (independent aftermarket, IAM) various types of special power transmission technology.
