Description
Technical field
The utility model belongs to engine art, specifically refers to a kind of engine mounting assembly.
Background technology
Heavy duty truck suspension system is very important part on car load, and its performance directly affects the vibration of automotive engine and even the traveling comfort of car load.The suspension system of heavy duty truck is divided into engine mounting and gear box suspension, and wherein engine mounting is the most key, and engine front mounting mainly bears twisting resistance, shearing force, and rear-suspending mainly bears pressure.
The dumping engineering truck now using is because applying working condition is very severe, suspension system bears very large impulsive force and shearing force, may cause the inefficacy of Engine Mounting System, makes troubles to client, have a strong impact on engine performance, serious words even can cause the damage of driving engine.
Fig. 1, Fig. 2 A, Fig. 2 B and Figure 3 shows that existing a kind of engine suspension device schematic diagram, indicate as follows: front supporting leg for engine 21, A crossbeam assembly 22 in figure, rubber cushion 23 before driving engine, driving engine rear leg 24, rubber cushion 25 after driving engine, engine rear support 8.
Engine front mounting refers to that the A crossbeam assembly that is arranged on the front support leg of engine body front end and be arranged on vehicle frame couples together by suspended rubber mat, and the power that front-suspension bears is less, and is mainly shearing force, adopts tilting 60 ° of layouts.Back suspension device of engine refers to that the rear leg on the clutch bell that is arranged on driving engine is connected by rear rubber cushion with the after poppet being connected with vehicle frame, and the power that rear-suspending bears is larger, and mainly bears pressure, is adopted as flat placed type and arranges.That suspension system plays is spacing, the effect of support and vibration isolation, and the performance of rubber cushion is subject to the impact of elastomeric material and sulfuration process.
Engine front mounting adopts 60 ° of layouts, and while preloading, rubber cushion deflection is larger, the little difficult assembling of arrangement space, and damping performance is poor.Back suspension device of engine parts are more, are difficult to dimension chain accurately to control, and easily cause the torsion, crooked of rubber cushion when assembling, affect the performance of whole system.Rear-suspending engine supporting leg is less with the area that links part of rubber cushion, makes the stressed too concentrated of rubber cushion, and rubber cushion is easily along bad.The tie bolt of rear-suspending leg and rubber cushion is smaller, can not bear the impact load under bad working environments; Rear-suspending rubber cushion simple in structure, under bad working environments, realizing middle limiting bolt 7 easily ruptures.
Utility model content
The purpose of this utility model is that the engine suspension device of existing use is proposed to technological improvement, and forward and backward suspended rubber mat strained condition is improved, and reduces the quantity of parts, and accurately controlling dimension chain, reduces the difficulty of assembling.
The utility model is achieved through the following technical solutions:
A kind of engine mounting assembly, includes front hung holder and rear suspension device;

After described driving engine rear leg and driving engine, rubber cushion is bolted; After described driving engine, rubber cushion is connected with vehicle frame;
The horizontal direction of described support baseboard and crossbeam in angle of 45 degrees.
Described front supporting leg for engine includes a L-type support and driving engine connecting panel; Described driving engine connecting panel is fixed on two face ends of L-type support; In described L-type support, on a face, be provided with mounting hole, be connected with front supporting leg for engine and support baseboard by bolt of rear end plate.
In described L-type support not with driving engine before the top of discontiguous of rubber cushion be provided with to a side projective structure; In described projective structure and L-type support not with driving engine before discontiguous of rubber cushion be same plane.
Described driving engine rear leg is ┫ shape structure, is provided with at least two fixed orifices in horizontal surface part.
In vertical surface part between two fixed orifices, be provided with reinforced rib.
The beneficial effects of the utility model are:
1, when the technical program allows engine suspension device prepackage, the space abundance of assembling, back suspension device of engine parts tail off, and dimension chain is more easily controlled, and assembles simpler;
2, the technical program adopts combined type suspended rubber mat, and combined type rubber cushion has better spacing measure with respect to common rubber cushion, and it is tightr that the skeleton structure variation of rubber cushion makes rubber part be connected with inside and outside skeleton, and the reliability of suspension system has obtained enhancing.
