Description
Technical field
The utility model relates to engine of heavy-duty car field engineering field, is specifically related to a kind of heavy duty truck engine suspension system.
Background technology
During existing car load assembling, driving engine is directly connected to above vehicle frame by engine bed 10 bolt 11.Heavily card engine power is large, work under bad environment, and output torque fluctuation is large, and vibration characteristic is severe, and cause car load NVH characteristic not good, parts work long hours in stronger vibration environment, easy endurance failure.NVH refers to: noise (noise), vibration (vibration) and the english abbreviation of sound vibration roughness (harshness).
Therefore, need to develop engine mounting, have suitable rigidity and arrangement form, meet the object of engine vibration energy decoupling, reduce the vibration passing between driving engine and vehicle frame as far as possible.On the one hand, engine mounting, as engine bearing system, can bear dynamic and static load under all operating modes, and makes a merit machine assembly displacement in all directions be in acceptable scope, does not interfere with other parts on chassis.On the other hand, driving engine itself is an inherent soruce of vibration, also be subject to the various obstacle of vibrations from outside simultaneously, as the vibrating isolation system of driving engine, play and reduce the vibration passing of engine vibration to vehicle frame, the vibration that produced by the driving engine transmission to vehicle frame and operator's compartment can be isolated fully, also reduce the transmission of road vibration excitation to driving engine simultaneously, reduce vibration noise.
Summary of the invention
The utility model is for the deficiency existed in background technology, and the technical matters that solve is: provide the heavy duty truck engine suspension system in a kind of engine mounting mounting means.
The utility model is for solving the problems of the technologies described above, the technical scheme taked is: a kind of heavy duty truck engine suspension system, comprise engine bed, its improvement is: also comprise mounting bracket and rubber module, rubber module is nested in mounting bracket, is connected by engine bed by rubber module bolt with mounting bracket.
Further, described mounting bracket is made up of base, stay bearing plate and brace panel, and stay bearing plate offers circular hole, and stay bearing plate one end is welded with base, become angle therebetween, and brace panel is connected between base and stay bearing plate;
Described rubber module is made up of rubber block, lining and Upper gasket, and lining one end is connected with Upper gasket end face, and rubber block to be socketed on lining and to be connected with Upper gasket end face;
Described rubber block is nested in described circular hole, configures a spacer for bolt between rubber block and engine bed.
Further, cavity is provided with in the end of described rubber block.
Compared with prior art, beneficial effect is the utility model: suspension system is used in the front-suspension in the assembling of heavy duty truck engine four point suspension, and front-suspension takes symmetrical mode layout.It is simple that the utility model has structure, and load-carrying capacity is strong, and anti-vibration performance is good, can improve the NVH characteristic of car load.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
See shown in Fig. 1 to Fig. 5, heavy duty truck engine suspension system, comprise engine bed 10, also comprise mounting bracket and rubber module, rubber module is nested in mounting bracket, is connected by engine bed 10 by rubber module bolt 11 with mounting bracket.Engine bed 10 is connected with driving engine by four bolts, nuts, and the base 1 of mounting bracket is directly connected with vehicle frame by four bolts, nuts.Engine bed 10 is Casting Parts, is directly connected with driving engine, tilts 45 ° with suspension system attachment face, and longitudinal direction of car direction tilts 3 °, the requirement of degree of dip low after high before ensureing driving engine.Engine bed 10 bottom design leaking hole, ensures that rainwater is got rid of in time, prevents rainwater from corroding the long period of soaking of engine bed 10.
Mounting bracket is made up of base 1, stay bearing plate 2 and brace panel 3, stay bearing plate 2 offers circular hole 4, and stay bearing plate 2 one end is welded with base 1, angle at 45 ° therebetween, and brace panel 3 is connected between base 1 and stay bearing plate 2; Be welded with cushion block 5 at the medial surface at circular hole 4 position of stay bearing plate 2, gain in strength.
Rubber module is made up of rubber block 6, lining 7 and Upper gasket 8, and lining 7 one end is connected with Upper gasket 8 end face, and rubber block 6 to be socketed on lining 7 and to be connected with Upper gasket 8 end face; Rubber block 6, lining 7 and Upper gasket 8 three sulfide, tight a bolt 11 time lining 7 play position-limiting action, make rubber block 6 uniform stressed, prevent rubber excessive deformation.
Rubber block 6 is nested in described circular hole 4, is interference fit, configures a spacer for bolt 9 between rubber block 6 and engine bed 10, then is linked together by the stay bearing plate 2 of engine bed 10 with mounting bracket with bolt 11.
Be provided with cavity 6-1 in the end of rubber block 6, when free state, cavity 6-1 is designed to collapsible curve form, and when bolt 11 is tightened, the flexural deformation of rubber block 6 foldable portion, cavity 6-1 disappears, and forms pretension compression.
After adopting the utility model, suspension system is used in the front-suspension in the assembling of heavy duty truck engine four point suspension, and front-suspension takes symmetrical mode layout.It is simple that the utility model has structure, and load-carrying capacity is strong, and anti-vibration performance is good, can improve the NVH characteristic of car load.
