Description
Technical field
The utility model is related to engine crankshaft twist vibration damper assembly.
Background technology
The effect of crankshaft tortional vibration damper assembly is that crank torque is transmitted feed pump, hydraulic pump, generator etc. by belt
Accessory drive its work, while reducing crankshaft system torsional oscillation by its damping effect, reduces what crankshaft torsional vibrations were brought to engine
Harm and the vibration and noise of minimizing car load.Therefore the high-performance enginer that crankshaft tortional vibration damper is widely used in now
On.
In Modern Engine, increasing new technology is integrated to be used in motor front-end wheel system, before causing engine
The torque of end train transmission is also increasing, therefore crankshaft tortional vibration damper assembly is required to need the torque that bears also therewith
Increase.Existing common crankshaft tortional vibration damper structure is that the wheel hub and belt pulley of crankshaft tortional vibration damper assembly are passed through vibration damping
The vulcanization of rubber press-fits connection, and crankshaft torque is directly delivered on wheel hub, and on wheel hub, torque is after vibration isolation rubber damping action
It is delivered on belt pulley, belt pulley brings engine wheel system to work.At this moment crankshaft tortional vibration damper is served and is started
Machine torsional oscillation delivers the function of bent axle spin moment again, but maximum being a risk that of this structure revolving compared with macromutation when engine
When torque or torsional oscillation, if in the case of rubber ring itself technique or quality are problematic, failing once occurs in vibration isolation rubber circle,
Crankshaft tortional vibration damper assembly will occur that global failure, front end wheel train quit work, and can travel to car load and bring danger, in order to
Major accident is avoided the occurrence of, therefore not only considers in the design of crankshaft tortional vibration damper assembly that vibration damping drop is turned round, while being also required to examine
Consider as, after crankshaft tortional vibration damper assembly failure, do not interfered with the safety of vehicle and personnel.
Content of the invention
Technical problem to be solved in the utility model is to provide a kind of the brand-new of engine crankshaft twist vibration damper assembly
Design structure, shadow engine caused after the design of this structure can be avoided when crankshaft tortional vibration damper assembly failure
Ring.
The technical solution of the utility model is as follows：
A kind of engine crankshaft twist vibration damper assembly, including belt pulley, vibration isolation rubber circle and inertia ring；The belt pulley
Core wheel hole be connecting portion with bent axle, directly to train, inertia ring press-fits connection by vibration isolation rubber circle to transmission crankshaft torque
Over pulleys carried.
Preferably, the inertia ring is fitted on the outside of belt pulley by vibration isolation rubber circle, and near bent axle connection end.
The ability that crankshaft tortional vibration damper assembly transmits crankshaft torque is such a construction increases, makes crankshaft tortional vibration damper total
Into vibration and noise reducing can be met, and can also transmit bigger crankshaft torque；The load that vibration isolation rubber circle bears is decreased simultaneously
Lotus, can improve the life-span of rubber ring；The relative slip tolerance between bent axle and belt pulley can be reduced；And if rubber ring occurs
In the case of failure, crankshaft tortional vibration damper assembly is that inertia ring does not play damping effect, but the torque of transmission train will not be received
Arriving affects, and torque transmission will not be failed, and engine is not in catastrophe failure.

Side）
Respectively it is numbered in figure：1st, conventional structure belt pulley；2nd, vibration isolation rubber circle；3rd, wheel hub；4th, inertia ring；5th, belt pulley.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Conventional crankshaft tortional vibration damper assembly is designed referring to Fig. 1 and Figure 1A, is usually designed to conventional structure, by belt pulley 1,
Vibration isolation rubber circle 2 and 3 three part of wheel hub composition, wheel hub 3 and conventional structure belt pulley 1 are vulcanized or are press-fited into by vibration isolation rubber 2
One entirety, wheel hub 3 is connected with bent axle, and transmission crankshaft torque is to conventional structure belt pulley 1.In this structure, crankshaft torsion
The belt pulley 1 of vibration damper complement had both play a part of to transmit torque for train, while the vibration damping played in crankshaft torsional vibrations system is used to again
Property ring effect.Although so design product design can be obtained more light, due to subtracting for crankshaft tortional vibration damper assembly
Shake rubber ring 2 engine work in need to bear the load that crankshaft system torsional oscillation brings, while still suffering from front end wheel train
Transmission crankshaft torque load, therefore vibration isolation rubber circle 2 easily there is degumming, fall glue and rubber tear quality problems.
Referring to Fig. 2 and Fig. 2A, crankshaft tortional vibration damper assembly of the present utility model is by belt pulley 5, vibration isolation rubber circle 2, used
Amount ring 4 is constituted.The core wheel hole of belt pulley 5 is the connecting portion being connected with bent axle, and directly transmission crankshaft torque is to train.Inertia ring 4
Press-fited by vibration isolation rubber circle 2 and be connected on the outside of belt pulley 5, and near bent axle connection end.
The vibration attenuation mechanism of this crankshaft tortional vibration damper assembly is rotation that is the same, being produced by inertia ring 4 with conventional structure
Turn inertia damping effect is reached under the damping action of vibration isolation rubber circle 2.Simply the utility model crankshaft tortional vibration damper is total
Into inertia ring 4 be each independent with belt pulley 5, inertia ring 4 simply plays damping effect, unlike conventional structure belt
Wheel 1 had both played inertia ring, also played train gearing.
5 body of belt pulley of this crankshaft tortional vibration damper assembly is that steel plate rotary press modelling is formed, uniform in pulley body
There is repeated hole, play loss of weight effect.Belt pulley 5 employs lighter steel plate materialses, and tensile strength is far above cast iron materials, through spinning
Technique makes, and type structure is simple, and light weight, balance quality are good, and surface texture density is high, is conducive to the use longevity for improving belt
Life, while reducing manufacturing cost and achieving the requirement of engine light-weight design.
The inertia ring 4 of this crankshaft tortional vibration damper assembly is by casting, is fitted in by vibration isolation rubber circle 2
Close and bent axle connection end on the outside of belt pulley 5.Inertia ring 4 is bigger due to external diameter, mass centre further away from pivot, then from
The rotary inertia of body is bigger.In the case where the rotary inertia for requiring to reach is certain, 4 external diameter of inertia ring is bigger, then its weight
Lighter, therefore inertia ring design on the outside of belt pulley 5 is fitted on belt pulley 5 by vibration isolation rubber circle 2, is conducive to song
The lightweight requirements of axle torsional vibration damper assembly.
The utility model also provides a kind of automobile, includes the crankshaft tortional vibration damper assembly of said structure, crankshaft torsion
Vibration damper complement is connected with bent axle by bearing by the core wheel hole of belt pulley 5, and directly transmission crankshaft torque is to train.
