Description
Technical field
The present invention, about a kind of auxiliary accessories of automotive engine, particularly provides the suspended rubber mat assembly of cushioning balance to the vibrations of automotive engine.
Background technology
Automotive engine is the important parts of automobile, its by a large amount of complex structures and the part of precision form.Simultaneously for ensureing the normal work of driving engine, supportingly with it also many accessories to be provided.
Such as no matter automobile is in normally starting, and still meets with the situation of outside roughness pavement, ensures that the normal operation circumstances of driving engine is a very important technical matters.For this reason, this area is provided for balancing and the suspended rubber mat parts of buffering engine vibration are exactly a necessary accessory.
The base model of suspended rubber mat parts has compression-type, shearing-type, compound type.The structure of compression-type is the simplest, is all generally that compression-type rubber cushion is in tilted layout, utilizes Partial Shear performance.Shearing-type rubber cushion due to rubber deformation large, the rubber cushion of simple application shear constitution is less.The structure fabrication of compound type rubber cushion is complicated, and performance is relatively better, but manufacturing cost and use cost is higher.
The manufacture of available engine front-suspension rubber cushion is all carry out sulfuration by rubber and metallic framework to form, and between rubber and metal, sulfuration process requires higher, and faying face is easily peeled off in using.Require in general design that metallic framework and vulcanization of rubber bond strength are sufficiently large, occurring to avoid bonding failure comes unstuck makes driving engine sinking fault.But after product quality problem or suspended rubber mat in high temperature environments Long-Time Service, the bond strength of adhesive surface can decline and cause and peels off and cause damaging.And existing engine mounting rubber cushion is integrated design due to rubber and metallic framework sulfuration, because suspended rubber mat is consumable accessory, needs to change whole rubber cushion and metallic framework, cause waste after ageing of rubber damage.
Be set up at cloth, the general tilting layout of existing engine front mounting rubber cushion, as shown in Figure 1, drop on the axes of inertia of dynamic assembly for making the elastic center of suspended rubber mat 20, suspended rubber mat 20 adopts symmetry to be in tilted layout, and on suspended rubber mat, lower skeleton is connected with mounting bracket 30 with suspension leg 10 with bolt respectively.Rubber bodies upper and lower surface respectively metal sulphide steel plate plays connection function.Because rubber property shear deformation is large, for avoiding distortion excessive, some suspended rubber mats increase one deck steel plate and make " sandwich " structure and improve anti-shear performance in centre.
Such rubber cushion utilizes compression and the cutting performance of rubber, but rubber is when bearing shearing force, and rubber deformation is larger.And rubber is out of shape relatively little when bearing merely compressive force.Rubber mounting distortion is excessive, engine location can be caused to change large.Driving engine and surrounding components occurrence dynamics is easily caused to interfere.Rubber compresses bearing of circulation and easily produces endurance failure in rubber inside under stretching operating mode in addition.The bond strength of adhesive surface can decline and cause and peels off and cause damaging.Occurring comes unstuck makes driving engine sinking fault.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of engine mounting rubber cushion assembly, the upper end of described suspended rubber mat assembly is fixedly connected with the engine supporting leg be connected with described driving engine, the engine bed that the lower end of described suspended rubber mat assembly is connected with same automobile chassis frame is fixedly connected with, wherein: the upper contact surface between described suspended rubber mat assembly and described engine supporting leg, and the lower contact surface between described suspended rubber mat assembly and described engine bed is all in horizontal arrangement, be that vertical direction is arranged to make the longitudinal axis of described suspended rubber mat assembly.
Technical solution of the present invention can ensure vibration damping and the decoupling zero of engine mounting all directions, effectively to guarantee in engine vibration respectively to limit function, and rubber wherein and steel plate do not need to carry out sulfuration, can solve insecure problem between polysulphide rubbers and steel plate.
