The invention provides a torsion damper and a parameter determination method. The torsion damper comprises a damper body and an adjusting mechanism, and the adjusting mechanism is connected with the damper body; the adjusting mechanism comprises an adjusting outer ring, an adjusting rubber ring, an adjusting inner ring and a mass ring, the adjusting rubber ring is coaxially sleeved with the adjusting outer ring, the adjusting outer ring and the adjusting rubber ring are fixed in the circumferential direction, the adjusting inner ring is coaxially sleeved with the adjusting rubber ring, the adjusting rubber ring and the adjusting inner ring are fixed in the circumferential direction, and the mass ring and the adjusting rubber ring are fixed in the circumferential direction. The adjusting outer ring and the adjusting inner ring are both detachably connected with the adjusting rubber ring, the mass ring is coaxially connected with the adjusting outer ring and detachably connected with the adjusting outer ring, and the adjusting inner ring is detachably connected with the shock absorber body. The problem that in the engine adjusting process, the adjusting cost is too high due to the fact that a large number of torsion dampers are manufactured can be solved, and the adjusting efficiency is improved.
Description
technical field [0001] The present disclosure relates to the technical field of automobiles, in particular to a torsional shock absorber and a parameter determination method. Background technique [0002] The front section of the crankshaft of the engine is usually equipped with a torsional vibration damper (TVD for short) to reduce the torsional vibration of the crankshaft. The torsional vibration energy of the crankshaft is gradually consumed in the torsional shock absorber to ensure the NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance of the car during driving. [0003] In the related art, the torsional vibration damper includes: a hub, a rubber ring and an inertia ring. The rubber ring is sleeved outside the hub, the inertia ring is sleeved outside the rubber ring, and the rubber ring is vulcanized and fixed between the hub and the inertia ring. In use, the hub fits over the end of the crankshaft to receive and dissipate the torsional vibrat...
