The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment is clearer, specific embodiment is described in detail below in conjunction with accompanying drawing.
Fig. 2 a, 2b are respectively the structure chart of driver's cabin left surface of the present utility model, right flank.As shown in the figure, the driver's cabin 200 of the loader that the utility model provides comprises the side backplate 201 that is located at both sides respectively, posts damping material 202 in the inboard of side backplate 201.This damping material 202 has stoped outside noise to enter in the driver's cabin effectively.
This damping material can use materials such as sound-absorbing sponge or rubber.
The sound-absorbing sponge can be used flexible polyurethane foam, is the good sound absorption material, helps further sound insulation and sound-absorbing.The backplate inboard sound-absorbing sponge reduction noise result of pasting in driver's cabin side is obvious, reduces about 1dBA than not pasting the sound-absorbing sponge
Below, use Fig. 3 that various noise improvement schemes are compared.Fig. 3 is the sketch of the various noise improvement schemes of expression driver's cabin.
Noise improvement through some row, noise is reduced to 83.0dBA from the highest 85.4dBA, first three measure is because the reduction noise is not obvious, cost has but improved, do not recommend to adopt, the 4th measure noise reduces obviously, has improved the driving room noise well, gives comfortable operating environment of driver.
Following table 1 has specifically been represented above-mentioned various noise improvement scheme.
Table 1
| No. | Improve content | Left (dBA) | Right (dBA) | Improve effect |
| No.1 | Initially | 85.4 | 83.2 | |
| No.2 | The sound absorber qualitative change more before the driver's cabin | 84.5 | 83.3 | The left side reduces about 0.9dBA, and the right side almost there is not variation. |
| No.3 | Add rubber below the No.2+ direction machine, alleviate vibrations | 84.3 | 82.9 | Left and right sides reduces 0.2dBA, DeGrain. |
| No.4 | The left back increase of No.3+ driver's cabin sponge | 83.9 | 83.8 | The left side reduces 0.4dBA, and the right side will increase 0.9dB A. |
| No.5 | The inboard subsides of No.4+ driver's cabin side backplate sound-absorbing sponge | 83.0 | 82.8 | The left side reduces 0.9dBA, and the right side reduces 1dBA, and effect is obvious. |
In addition, by reducing noise in the inboard subsides of driver's cabin side backplate sound-absorbing sponge, as shown in the following Table 2, noise is reduced to 83dBA by the preceding left side 83.9dBA of test, and 82.8dBA is reduced to by 83.8 in the right side, the about 1dBA of the range of decrease, and effect is obvious.
Table 2
| Distinguish | Before the improvement | After the improvement | Reduce |
| The high noisy in left side | 83.9 | 83.0 | 0.9 |
| The high noisy in right side | 83.8 | 82.8 | 1 |
In addition, Fig. 4 is the descend post figure of tangible frequency field of the noise of expression the utility model driver's cabin.As shown in Figure 4, by pasting the sound-absorbing sponge in that driver's cabin side backplate is inboard, that finds that noise descends near 500～2000Hz is many, thinks that the sound-absorbing sponge mainly absorbs the hydraulic oil container and fluid pressure line generation noise that distributes about the driver's cabin bottom.
In sum, the backplate inboard sponge reduction noise result of pasting in driver's cabin side is obvious, can approximately reduce about 1dBA, and the noise reduction cost is not high, only needs 2 sound-absorbing sponges, the sound-absorbing sponge of for example long approximately 900mm, wide 250mm.
The utility model embodiment also provides a kind of loader, comprises vehicle frame and the driver's cabin that is arranged on the described vehicle frame, and described driver's cabin comprises the side backplate that is located at both sides respectively, posts damping material in the inboard of described side backplate.
In the above-mentioned loader, described damping material is sound-absorbing sponge or rubber tile.
And in the above-mentioned loader, described sound-absorbing sponge is a flexible polyurethane foam.
Hence one can see that, the utlity model has following advantage.
The utility model is by pasting damping material in the side of driver's cabin both sides backplate inboard, can prevent that effectively external noise from entering in the driver's cabin with low cost, thereby reduced the driving room noise, for the driver operation enhancement of environment, alleviate tired driver, prevent that the driver from producing maloperation owing to tired, plays good effect.
And the sound-absorbing sponge is used flexible polyurethane foam, is the good sound absorption material, helps further to reduce noise.
In addition, the utility model is reduced to 83dBA with the noise in original driver's cabin from testing preceding left side 83.9dBA, and 82.8dBA is reduced to by 83.8 in the right side, and the about 1dBA of the range of decrease has the good sound absorption effect, has improved the comfortableness of the manipulation environment of driver's cabin inside.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
