Abstract
The utility model discloses an engine hydraulic suspension, which comprises a main rubber spring, a bolt framework, a slanting rear cover and a plastic partition plate, wherein the bolt framework is arranged on the upper portion of the vulcanized main rubber spring, the slanting rear cover is arranged on the lower portion of the main rubber spring, and the plastic partition plate is positioned between the main rubber spring and the rear cover. The main rubber spring includes a rubber body and an upper framework integrally vulcanized, a gap is reserved between the main rubber spring and the lateral wall of the bolt framework which are connected through a rivet, a sealing leather cup forming a sealed cavity with the main rubber spring is arranged on the lower portion of the plastic partition plate, an iron partition plate is arranged between the plastic partition plate and the sealing leather cup, and an upper cavity is formed between the plastic partition plate and the main rubber spring. By means of the combined structure of the main rubber spring and a hydraulic cavity, the technical problem that existing engine suspensions are not good in vibration damping, vibration isolation and silencing effect can be effectively resolved.
Description
Technical field
The utility model belongs to automobile suspending shock-absorbing device field, relates in particular to a kind of engine hydraulic mount.
Background technique
None is not to adopt yielding support to install for the Hyundai Motor motor, and this is referred to as " suspending " in automobile industry, then is a vibration isolation problem in mechanics and vibration engineering.If directly motor is fixed tightly on the automobile 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 motor will cause vehicle frame, vehicle body to produce disgusting construct 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 motor installation and movement process in addition.Chinese patent CN2069808 discloses a kind of engine hydraulic mount, relate to and be used for the vibration damping equipment that motor car engine is installed, its base is formed by connecting by cylindrical shell and base plate, the anchor plate of round nut and rubber mount are packaged in the cylindrical shell, rubber mount can be divided into cushion and following cushion, the block rubber of inner filling tape skeleton, and this invention has improved the force-bearing situation that suspends, save location piece, improved bearing capacity and working 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 travelling comfort that the passenger takes.
Summary of the invention
The utility model mainly is the technical problem that solves existing in prior technology engine mounting vibration damping, vibration isolation, quiet poor effect etc., a kind of engine hydraulic mount is provided, efficiently solves the technical problem of engine mounting vibration damping, vibration isolation, quiet poor effect.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: it comprises rubber spring, be located at and vulcanize in rubber spring upper bolt skeleton, be located at the slope shape bonnet of rubber spring bottom, plastic septum between rubber spring and bonnet, described rubber spring comprises sulfuration all-in-one-piece rubber body and upper skeleton, be provided with the gap between the sidewall on the described bolt skeleton whole body and the described rubber spring, and connect by rivet, described plastic septum bottom is provided with the sealing cup of forming sealed cavity with rubber spring, be provided with the iron dividing plate between plastic septum and the sealing cup, form upper chamber between described plastic septum and the rubber spring.The utility model is installed between motor and the frame, and the motor and the frame of high frequency are isolated, and the impact force that produces when preventing engine operation is directly delivered on the frame; And utilize the rubber 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, dynamic load as main load-supporting part, and it is stressed that upper skeleton has alleviated rubber body, strengthened the rigidity of rubber body, and adopts the sulfuration structure, has guaranteed sealing of the present utility model again.Plastic septum and iron dividing plate are divided into two-part 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 Changes 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 plastics leather cup absorbs the variation of cavity inner volume by distortion.Plastic septum mainly is to produce dither when the little amplitude of high frequency, and the liquid energy of the feasible plastic septum of flowing through reaches decay.It is to be the V-type setting that the slope shape bonnet is set, and the utility model adopts suspending of V-type, has bigger lateral stiffness.
As preferably, described bolt skeleton comprises the aluminium fuse, and described aluminium fuse is provided with connecting bolt.The aluminium fuse can prevent the connecting bolt rotation.
As preferably, described bonnet is provided with fixing bolt, and described fixing bolt and connecting bolt are the angle settings of 5 to 30 degree.
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 corrosivity of the utility model internal material.
As preferably, described iron dividing plate and plastic septum are provided with the runner hole.When flow of liquid behind the runner hole, liquid will lose lot of energy, thus reach the vibration free damped purpose.
As preferably, described sealing cup and described bonnet are at interval.Bonnet is used to protect sealing cup, prevents that it from sustaining damage.
The beneficial effect that the utility model brings is that the utility model adopts the composite structure of rubber spring and hydraulic chamber, efficiently solves the technical problem of engine mounting vibration damping, vibration isolation, quiet poor effect.
