The upper end and the lower end of the engine mounting rubber mat assembly are fixedly connected with an engine stand bar and a support respectively, an upper contact surface between the engine mounting rubber mat assembly and the engine stand bar and a lower contact surface between the engine mounting rubber mat assembly and the engine support are both horizontally arranged to enable the longitudinal axis of the engine mounting rubber mat assembly to be arranged in the vertical direction, vibration attenuation and decoupling in each direction of engine mounting can be guaranteed, and sulfidizing is not required.
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, and it is comprised of a large amount of complex structures and accurate part.Simultaneously for guaranteeing the normal operation of driving engine, supportingly with it also to provide many accessories.
For example no matter automobile is in normally starting, and still meets with the situation of outside roughness pavement, guarantees that the normal operation circumstances of driving engine is a very important technical matters.For this reason, this area be provided for balance and buffering engine vibration suspended rubber mat parts be 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, and utilizes Partial Shear performance.Shearing-type rubber cushion is because rubber deformation is large, and the rubber cushion of applying merely 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 to be vulcanized and formed by rubber and metallic framework, and between rubber and metal, sulfuration process is had relatively high expectations, and faying face is easily peeled off in using.In general design, require metallic framework and vulcanization of rubber bond strength enough greatly, to avoid bonding failure to occur coming unstuck, to make driving engine sinking fault.But because product quality problem or suspended rubber mat are under hot environment after long-term use, the bond strength of adhesive surface can decline and cause and peel off and cause damaging.And existing engine mounting rubber cushion is because the sulfuration of rubber and metallic framework is integrated design, and because suspended rubber mat is consumable accessory, ageing of rubber needs to change whole rubber cushion and metallic framework after damaging, and causes waste.
At cloth, be set up, the general tilting layout of existing engine front mounting rubber cushion, as shown in Figure 1, for the elastic center of suspended rubber mat 20 is dropped on the axes of inertia of dynamic assembly, 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 the leg 10 that suspends with bolt respectively.Rubber bodies upper and lower surface respectively metal sulphide steel plate plays connection function.Because rubber property shear deformation is large, excessive for avoiding being out of shape, some suspended rubber mats increase one deck steel plate and make " sandwich " Structure Improvement 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 that rubber is out of shape when bearing compressive force is merely relatively little.Rubber mounting distortion is excessive can cause engine location change large.Easily cause driving engine and the dynamic interference of parts generation around.Rubber easily produces endurance failure in rubber inside bearing under compression and stretching operating mode of circulation in addition.The bond strength of adhesive surface can decline and cause and peel 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 being connected with described driving engine, the lower end of described suspended rubber mat assembly is fixedly connected with the engine bed that same automobile chassis frame is connected, 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 horizontal arrangement, so that being vertical direction, arranges the longitudinal axis of described suspended rubber mat assembly.
Technical solution of the present invention can guarantee vibration damping and the decoupling zero of engine mounting all directions, can effectively guarantee in engine vibration each to limit function, and rubber wherein and steel plate do not need to vulcanize, can solve insecure problem between polysulphide rubbers and steel plate.
