Abstract
The utility model relates to an engine crankshaft multi-stage series torsion vibration damper which comprises a primary torsion vibration damper, a secondary torsion vibration damper and an oil-containing bearing, wherein the primary torsion vibration damper comprises an outer wheel boss, the inner side of the outer wheel boss is provided with a rubber vibration damping ring, the upper side of the rubber vibration damping ring is provided with a geared ring, the secondary torsion vibration damper comprises an inner wheel boss, the upper side of the inner wheel boss is provided with an another rubber vibration damping ring, the primary torsion vibration damper and the secondary torsion vibration damper are connected in series through the outer wheel boss, and the oil-containing bearing is arranged between the two rubber vibration damping rings. The vibration damper has the beneficial effects that the damping coefficient of the vibration damper doubly increases, and the amplitude of the damping reduces correspondingly, which improves the vibration-damping performance, and enables the drive inertia of an engine to be completely cleaned out, thereby improving the performance of the engine, and prolonging the service life of an engine crankshaft.
Description
Technical field
The utility model relates to a kind of engine crankshaft plural serial stage tandem type torsional vibration damper.
Background technique
At present, the rotary inertia no regularity of bent axle in the Crankshaft System of Automobile Engine system, easily produce vibration and noise, what extensively adopt in the Crankshaft System of Automobile Engine system is to improve engine performance and life-span at crankshaft front end mounting dampers (rubber damping formula single-stage torsional vibration damper), reduce vibration and vibration noise on the bent axle all directions, the engine crankshaft vibration damper mostly is to adopt the single-stage vibration damper, by gear ring, wheel hub and middle damping ring are formed, the damping constant value of this one pole rubber damping formula torsional vibration damper is less than normal, usually do not reach the vibration damping requirement of crankshaft system, and working life is shorter, when middle vibration isolation rubber wears out, engine temperature is higher, and its damping property obviously descends.Therefore need a kind of engine crankshaft plural serial stage tandem type torsional vibration damper, damping constant is increased exponentially, the amplitude of damping is corresponding to be reduced, improved damping property, the transmission inertia of motor is fully removed, thereby improved engine performance, prolong the life-span of engine crankshaft.
The model utility content
Problems such as the purpose of this utility model provides a kind of engine crankshaft plural serial stage tandem type torsional vibration damper, and, the life-span less than normal with the damping constant value that overcomes one pole rubber damping formula torsional vibration damper is short.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of engine crankshaft plural serial stage tandem type torsional vibration damper, comprise one-level torsional vibration damper, secondary torsional vibration damper and oil-impregnated bearing, described one-level torsional vibration damper comprises outer wheel hub, and the inboard of outer wheel hub is provided with a rubber damping ring, and the top of described rubber damping ring is provided with gear ring; Described secondary torsional vibration damper comprises inner wheel hub, and the top of inner wheel hub is provided with another rubber damping ring, is connected in series by described outer wheel hub between described one-level torsional vibration damper and the secondary torsional vibration damper, and is interference fit; Described oil-impregnated bearing is located between the described two rubber damping rings, and has certain pretightening force between the described two rubber damping rings.
The beneficial effects of the utility model are: a kind of engine crankshaft plural serial stage tandem type torsional vibration damper, be connected in series by outer wheel hub between one-level torsional vibration damper and the secondary torsional vibration damper, interference fit, damping constant is increased exponentially, the amplitude of damping is corresponding to be reduced, and has improved damping property, and the transmission inertia of motor is fully removed, thereby the raising engine performance, the life-span of prolongation engine crankshaft; Under engine start and no-load condition, moment of torsion that engine crankshaft plural serial stage tandem type torsional vibration damper transmission inertia produces and vibration are maximum, adopt this structure to reduce moment of torsion and vibration.
