Abstract
The utility model discloses a hydraulic excavator engine suspension system and belongs to the field of excavator parts. The hydraulic excavator engine suspension system comprises two rubber damping blocks, the rubber damping blocks are mounted on upper and lower sides of mounting holes of a vehicle frame, the hydraulic excavator engine suspension system further comprises two damper housings, the two damper housings respectively wrap the upper and lower rubber damping blocks, the rubber damping blocks and the damper housings are arranged below an engine support and longitudinally symmetrical with an engine mounting supporting seat of the vehicle frame as a standard, the rubber damping blocks and the damper housings are mounted on the engine support and the vehicle frame through bolts, the rubber damping blocks are formed by elastic rubber bodies and steel core structures, compression allowance is reserved, and mounting end faces of the rubber damping blocks, which are in contact with the vehicle frames, are in rigid structures. The hydraulic excavator engine suspension system has the advantages that the structure is simple, manufacturing and assembly are convenient, damping effects are good, the transmission of vibration of an engine in three directions to a whole vehicle can be effectively damped, reliability and using performances are high, and damping requirements of the hydraulic excavator engine under various working conditions can be met.
Description
Technical field
The utility model relates to a kind of Engine Mounting System, and specifically a kind of hydraulic excavator engine suspension system, belong to the excavator field of components.
Background technique
Along with the development of economic society and scientific and technical progress, the operation comfort of engineering machinery more and more causes people's attention.The vibration noise that reduces engineering machinery is one of key factor improved operation comfort.A large amount of theoretical and practices show, the vibration noise of engineering machinery is mainly that the vibration due to motor causes.For excavator sector, what most excavators adopted is the poor four cylinder engine of balance, so the vibration isolation problems of motor is particularly outstanding, also more and more higher to the designing requirement of Engine Mounting System.The suspension system of motor must have enough vibration isolation measures, prevents that the vibration of motor is delivered to car load, to strengthen the protective action to motor.Traditional Engine Mounting System is just obvious for damping effect on vertical direction, because the position of engine mounting position and each rank mode of flexural vibration node of motor does not overlap, causes motor damping effect in the horizontal direction poor.
Summary of the invention
The utility model provides a kind of hydraulic excavator engine suspension system, the transmission of the vibration of motor on three directions to car load can decay, effectively alleviate the impact that engine luggine brings power assembly and car load, reduce the vibrations noise, improve the reliability of motor, extend the working life of motor.
To achieve these goals, the technical solution adopted in the utility model is: this hydraulic excavator engine suspension system, comprise two damping rubber blocks, damping rubber block is arranged on the upper and lower both sides of mounting hole of vehicle frame, also comprise two vibration damper cases, two vibration damper cases wrap respectively upper and lower two damping rubber blocks;
Described damping rubber block and vibration damper case are placed on engine support below, and the engine-mounting bracket of vehicle frame of all take is the upper and lower symmetrical placement of benchmark;
Described damping rubber block and vibration damper case are arranged on engine support and vehicle frame by bolt; Damping rubber block is comprised of elastic rubbery body and structure of steel pole, is reserved with the compression surplus, and the installation end face contacted with vehicle frame is rigid construction.
As improvement of the present utility model, described vibration damper case is rigid construction, and soundness is better, can bear powerful impact force, has effectively prevented the damping rubber block distortion, extends the working life of car load.
The beneficial effects of the utility model are: absorb the energy of generation of vibration by the viscoelasticity characteristic of rubber, prevent that motor from producing laterally and vertically toppling.When this device installs, compressed and the stored energy of the reserved surplus of damping rubber block, when motor produces horizontal, vertical and vertical vibration, damping rubber block releases energy to be cushioned, thereby reduces the impact of engine luggine on power assembly and car load.The utility model is simple in structure, manufacture and easy to assembly, damping effect is better, but the vibration of effective attenuation motor on three directions is to the transmission of car load, and reliability and usability are high, can meet the damping requirement of hydraulic excavator engine under various operating modes.

Fig. 2 is the utility model partial structurtes schematic diagram;
Fig. 3 is the utility model damping rubber block and vibration damper casing structure schematic diagram.
In figure: 1, damping rubber block, 1-1, elastic rubbery body, 1-2, structure of steel pole, 2, the vibration damper case, 3, the compression surplus, 4, vehicle frame, 5, engine support.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, this hydraulic excavator engine suspension system, by two damping rubber blocks 1 and two vibration damper cases 2, formed, damping rubber block 1 is contained in respectively the upper and lower both sides of mounting hole of vehicle frame 4, vibration damper case 2 wraps respectively upper and lower two damping rubber blocks 1, described damping rubber block 1 and vibration damper case 2 are placed on engine support 5 belows, the engine-mounting bracket of vehicle frame 4 of all take is upper and lower symmetrical placement of benchmark, and then pass through bolt, packing ring is arranged on damping rubber block 1 and vibration damper case 2 on engine support 5 and vehicle frame 4, with self-locking nut, it is fixed.
Described damping rubber block 1 is comprised of elastic rubbery body 1-1 and structure of steel pole 1-2, be reserved with compression surplus 3, and the installation end face contacted with vehicle frame 4 is rigid construction, and vibration damper case 2 is rigid construction.Vibration damper case 2 internal surfaces contact with damping rubber block 1 outer surface, absorb the energy of generation of vibration by the viscoelasticity characteristic of rubber, prevent that motor from producing laterally and vertically toppling.When this device installs, compressed and the stored energy of the reserved surplus of damping rubber block 1, when motor produces horizontal, vertical and vertical vibration, damping rubber block 1 releases energy to be cushioned, thereby reduces the impact of engine luggine on power assembly and car load.
