Background technology
None is not to adopt elastic support to install for the modern automobile driving engine, and this is referred to as " suspending " at auto trade, then is a vibration isolation problem in mechanics and vibration engineering.If directly driving engine is fixed tightly on the automobile chassis frame rigidly, then when travelling on uneven road surface, automobile will cause fuselage owing to distortion, the impact of vehicle frame damage without middle elastic members; And the vibration from driving engine will cause vehicle frame, vehicle body to produce disgusting constructional noise when exercising on the road surface of automobile at flat-satin.Elastic mounting can also compensate the inaccuracy of the relative position that is caused by the vehicle frame distortion in engine installation and motion process in addition.Chinese patent CN2069808 discloses a kind of driving engine vibrationproof and has suspended, relate to and be used for the shock attenuation unit that automotive engine is installed, its base is formed by connecting by cylindrical shell and base plate, the anchor plate of circular nut and rubber mount are packaged in the cylindrical shell, rubber mount can be divided into cushion and following cushion, the rubber block of inner filling tape skeleton, and this invention has improved the force-bearing situation that suspends, save spacer, improved load-carrying capacity and service life.But the poor effect of its vibration damping and vibration isolation is difficult to satisfy the vibration damping and vibration isolation requirement of automobile under each operating mode, is difficult to satisfy the traveling comfort that the passenger takes.
Summary of the invention
The utility model mainly is the technical matters that solves existing in prior technology engine mounting vibration damping, vibration isolation, quiet poor effect etc., provide a kind of driving engine vibrationproof to suspend, efficiently solve the technical matters of engine mounting vibration damping, vibration isolation, quiet poor effect.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: it comprises rubber spring, leather package with rubber spring composition closed cavity, described rubber spring comprises sulfuration all-in-one-piece bolt skeleton, rubber bodies and upper skeleton, be provided with plastic septum between described rubber spring and the leather package, described plastic septum is separated into upper chamber and lower chambers with described seal chamber, described bolt skeleton stretches into downwards in the described upper chamber, described bolt skeleton lower end is connected with bowl a type skeleton and a pull head, described bowl type skeleton is separated into two chambers with upper chamber, described plastic septum top is provided with the iron dividing plate, described leather package is arranged on described plastic septum bottom, and the bottom of described leather package is connected with bonnet.The utility model is installed between driving engine and the frame, and the driving engine and the frame of high frequency are isolated, and the impulsive force that produces when preventing engine operation is directly delivered on the frame; And utilize the caoutchouc elasticity deformation characteristic, impacting the free damping that produces during with engine operation stops as early as possible, further, adopt liquid to charge into upper and lower cavity for improving vibration absorption ability, flowing of liquid improved the effect of vibration damping, sound insulation during by vibration, reduce the rhythm of engine, reduce resonance and produce.Rubber spring of the present utility model bears side direction and vertical quiet, live load as main load-supporting part, and it is stressed that upper skeleton has alleviated rubber bodies, strengthened the rigidity of rubber bodies, and adopts the sulfuration structure, has guaranteed leak tightness of the present utility model again.Plastic septum and iron dividing plate are divided into two parts up and down with the enclosed cavity in the rubber spring, be filled with the liquid of strengthening the utility model damping in the cavity, volume change when rubber spring is out of shape in the epicoele, impel liquid in upper and lower cavity, back and forth to flow, after flow through plastic septum and the free damping of iron dividing plate, be tending towards gradually stopping, the liquid plastics leather cup absorbs the variation of cavity inner volume by distortion.Plastic septum mainly is to produce high-frequency vibration when the little amplitude of high frequency, and the liquid energy of the feasible plastic septum of flowing through reaches decay.Bowl type skeleton is used to protect rubber spring; prevent that it from producing excessive deformation and damage, on the other hand upper chamber is separated into two chambers, strengthened the resistance of flow of liquid; and pull head is to guarantee that bowl type skeleton smoothly contacts with plastic septum with the iron dividing plate, prevents the damage of iron dividing plate and plastic septum.
As preferably, the middle part of described rubber spring outer wall is provided with Connection Block, and described Connection Block comprises two connecting arms, and described connecting arm is provided with screw.Adopt the Connection Block structure, it is more firm to make that the utility model is connected with driving engine.
As preferably, described bolt skeleton comprises the aluminium fuse, and described aluminium fuse is provided with tie bolt, and described upper skeleton is the aluminium frame, and described upper skeleton is outer skeleton.The aluminium fuse can prevent tie bolt rotation and axial motion.
As preferably, described rubber bodies inwall is arranged to the stepped wall shape, and described bowl type skeleton is outer enlarging shape, and the rim of a bowl of described bowl of type skeleton bottom extends to the lower surface of the stepped wall of described rubber bodies.Adopt the bowl type skeleton of this structure, make the skeleton ability have certain elasticity, and strengthen having limited to rubber spring to displacement.
As preferably, described pull head is arranged on the bowl position, the end on described bowl type skeleton top, and described pull head is outside to be integral with the vulcanization of rubber.
As preferably, be filled with water and ethylene glycol in the described upper chamber.The viscosity-temperature characteristics of ethylene glycol are stable, and are lower for the corrosive property of the utility model internal material.
As preferably, described iron dividing plate and described plastic septum are provided with the runner hole.When flow of liquid behind the runner hole, liquid will lose lot of energy, thereby reach the free damped purpose of vibration, the gap is set will increase liquid resistance, shorten the free damped time of vibrating.
As preferably, the bottom surface of described leather package and described bonnet form a cavity.
As preferably, described bonnet is a plastic rear cover.Adopt plastic rear cover to alleviate deadweight of the present utility model further.
The beneficial effect that the utility model brings is, the utility model adopts the unitized construction of rubber spring and hydraulic chamber, efficiently solves the suspend technical matters of vibration damping, vibration isolation, quiet poor effect of driving engine vibrationproof.
