Abstract
The utility model discloses a connecting structure for fixing a cylinder cover shield, which solves the vibration response problem of shied parts through reducing the transmission of vibrational energy by adopting vibration isolation measures, so as to realize vibration reduction and noise reduction. The connecting structure adopts the scheme that a vibration reduction sealing gasket is adhered to the bolt connecting a cylinder cover and a cylinder cover shield. The utility model has the advantage that part of the vibration energy can be absorbed through the damping action of the additionally arranged flexible vibration reduction sealing gasket, and can be released in the form of heat, thereby realizing vibration reduction.
Description
Technical field
The utility model relates to a kind of automobile connection set, relates in particular to a kind of bolt connecting device of stationary cylinder housing of effectively vibration damping.
Background technique
Vibration is the source of sound, thereby noise and vibration also just has closely contact, vibrates greatly more, and noise is just big more.According to statistics, the overall noise 70% of motor car engine is from Surface Radiation Noise, cover type components such as oil sump, timing tooth cover and cylinder head cover are main Surface Radiation Noise sources, these parts all are to be fixed on bigger structural of rigidity, the rigid material damping is little, the vibration that produces is big, and noise is also just big.A kind of vibration and noise reducing bolt assembly device that on October 18th, 2006 is open, publication number is CN2828414 discloses such solution: described vibration and noise reducing bolt assembly device comprises case bolting pad, case bolt bush, case bolt, the case bolt is arranged in the case bolt bush, and the outer top of case bolt bush is with the case bolting pad.Such solution still exists deficiency, adopts this scheme when mounted, assembles loaded down with trivial detailsly, and parts are forgotten easily, and difficulty is installed, and because lining is thinner, can only play faint damping effect, and total effectiveness in vibration suppression is unsatisfactory.
The model utility content
The utility model provides a kind of linkage structure of stationary cylinder housing, has reduced the transmission of vibrational energy by vibration isolation measure, has solved this problem of vibratory response of case type component, has realized the purpose of vibration and noise reducing.
For solving the problems of the technologies described above, the linkage structure of a kind of stationary cylinder housing of the present utility model, it is characterized in that, cylinder head cover is connected on the cylinder cap by bolt, be provided with bolt hole on cylinder head cover, bolt is located in the bolt hole, is equipped with boss in two ends up and down at bolt, be attached with the vibration damping sealing gasket on the bolt, the vibration damping sealing gasket is located at up and down between two boss.Because the damping characteristic of the size of structural member vibration noise and himself structure, damping material is closely related.Attached to the bolt surface, utilize the viscoelastic property of damping material that a part of vibrational energy is absorbed damping material, disperse with the form of heat again, reduced to be delivered to the vibration of cylinder head cover.Under the prerequisite that does not change machine sound radiation characteristic, effectively control the vibration transfer between parts like this, thereby realized the purpose of vibration and noise reducing.Because damping material is to be attached directly on the junction plane of bolt and cylinder head cover, saved assembling action of the prior art, avoided parts easily to pass into silence, install problems such as difficulty, and the relative prior art of vibration-absorptive material thickness of adhering to and Yan Yaohou, can play the purpose of vibration damping better.
Junction plane attached to the vibration damping sealing gasket on the bolt and clamping bolt and cylinder head cover fits, and the sealing gasket shape is decided with the junction plane situation.As optimization, it is round table-like or cylindrical that the vibration damping sealing gasket is, and the upper and lower end face diameter of sealing gasket is between 3 to 10 millimeters.The vibration damping sealing gasket is made specific shape, helps sealing gasket and junction plane ground and effectively fits, and can play better reduction effect to vibration.The vibration damping sealing gasket is attached on the bolt, and thickness must be controlled in the scope, because the material that adheres to is crossed the thin effect that then can not play vibration damping, the blocked up fixed effect that then can influence bolt.
As preferably, the material of vibration damping sealing gasket adopts the macromolecular material of high damping.Under the situation of same dynamic excitation, the damping of material is big more, and structural vibration is weak more, noise is low more, has adopted the material of high damping, can more efficiently the vibrational energy that passes over be absorbed to transform control vibration, vibration and noise reducing.
As preferably, the thickness of vibration damping sealing gasket equates with the distance between two boss up and down of bolt.Such design can make sealing gasket better be fixed on the bolt, and sealing gasket can combine with bolt is better, unsettled situation can not occur adhering to.
The beneficial effects of the utility model: by adhering to the damping sealing gasket at connecting bolt, the damping function by rubber reduces transfer of vibration.Just can effectively avoid the vibration transfer that is rigidly connected and caused like this under the prerequisite that does not change the cylinder head cover structure, thereby reach the purpose of vibration and noise reducing, implementation method is simple.
