Definitions
- the present invention relates to a vibration isolator for suppressing vibrations of an engine equipped in a construction machine, for example.
- an engine installed in a construction machine or the like is elastically supported through a vibration isolator having a rubber-like elastic body, and is resistant to vibrations generated by the engine itself and vibrations of a vehicle body during running and excavation work on uneven surfaces. The resulting engine vibration is suppressed.
- the anti-vibration device often supports the engine at four points by combining a set of anti-vibration devices that vertically support the engine and a set of anti-vibration devices that support the engine at an inclination.
- the vibration isolator for vertical support effectively elastically supports the heavy engine that vibrates in the vertical direction, and the vibration isolator for tilt support in addition to the force in the vertical direction, It is designed to receive horizontal force due to engine vibration.
- the vibration isolator for vertical support cannot receive sufficient force in the horizontal direction, and the whole engine vibrates in the direction of turning horizontally around the position of the vibration isolator for tilt support.
- the vibration isolator for vertical support is greatly displaced in the shear direction (horizontal direction).
- the displacement in the shearing direction of the vertical support vibration isolator tends to cause a crack in the rubber-like elastic body. To prevent this crack and improve the durability, it is necessary to enlarge the vibration isolator.

Can do. Thereby, it is possible to prevent damage to the rubber-like elastic body due to displacement in a direction orthogonal to the central axis while elastically supporting the engine and suppressing engine vibration, without increasing the number of parts. Therefore, the vibration isolator can be reduced in size and sufficient durability can be obtained.

- the anti-vibration rubber 10 is overlaid on the lower end plate 7, and the guide member 9 is overlaid on the inner cylinder 4 of the anti-vibration rubber 10 so as to lock the step 16.
- the guide member 9 has a circular and vertically symmetric structure, and the guide member 9 is surrounded by the cylindrical portion 12 of the outer ring 6 to prevent the guide member 9 from slipping off.
- the assemblability of the apparatus 1 can be improved (see FIG. 14).
- a bolt 11 protruding from the lower surface side of the frame side bracket 5 is inserted into the center hole 7a, 4a, 9a of the set end plate 7, inner cylinder 4 and guide member 9, and a nut is fastened to the bolt 11 to dampen the vibration isolator. 1 is completed (see FIG. 13D).
- the guide member 9 is provided in the vibration isolator 1, and the horizontal movement of the inner cylinder 4 is restricted without hindering the movement of the inner cylinder 4 in the vertical direction. It is possible to prevent damage due to horizontal shear deformation.
- This elastically supports the engine 2 installed in construction machinery and the like, and suppresses vibration generated by the engine 2 itself and vibration of the engine 2 caused by running on uneven surfaces and vibration of the vehicle body during excavation work.
- the durability of the vibration isolator 1 can be improved.
- the gap 17 is provided between the guide member 9 and the outer ring 6, it is possible to absorb the dimensional error of each member and part, and to facilitate the assembly of the vibration isolator 1 to the frame side bracket 5. Can do.
- FIG. 15 is a diagram illustrating the relationship between the horizontal load acting on the inner cylinder 4 and the horizontal displacement of the inner cylinder 4.
- the vertical axis represents the horizontal load acting on the inner cylinder 4, and the horizontal axis Indicates the horizontal displacement of the inner cylinder 4.
- FIG. 15 shows three types of relationships in which the inner diameter of the outer ring 6 is constant and the outer diameter of the guide member 9 is different.
- the outer diameter of the guide member 9 is represented by (A), (B), ( C) is set in the smaller order ( ⁇ A ⁇ B ⁇ C).
- the horizontal rigidity of the vibration isolator 1 can be reduced in a range where the horizontal displacement is small, and the inner cylinder 4 can be easily displaced in the horizontal direction, It is possible to absorb a dimensional error of each member or component. Further, after the horizontal displacement is increased and the gap 17 is closed, the horizontal rigidity of the vibration isolator 1 is increased, and further displacement in the horizontal direction is restricted.
- the size of the gap 17 can be appropriately set in consideration of interference between components.
- the vibration isolator 1 can be set to various spring characteristics, and the degree of freedom in designing the vibration isolator 1 can be increased.
- FIG. 16 is a diagram illustrating the relationship between the vertical load acting on the inner cylinder 4 and the vertical displacement of the inner cylinder 4, and the vertical axis represents the vertical load acting on the inner cylinder 4. Indicates the vertical displacement of the inner cylinder 4.
- FIG. 16 shows three types of relationships in which the inner diameter of the cylindrical portion 13 is constant and the outer diameter of the rubber-like elastic body 8 is different.
- the outer diameter of the rubber-like elastic body 8 is expressed by (A), ( B) and (C) are set larger in this order ( ⁇ A> ⁇ B> ⁇ C).
- the vertical rigidity of the vibration isolator 1 can be reduced in a range where the vertical displacement is small, and after the vertical displacement is increased and the gap 15 is closed. Can increase the vertical rigidity of the vibration isolator 1.
- this invention is not limited to said embodiment, A change can be suitably added within the scope of the present invention.
- the rubber-like elastic body 8 is disposed between the inner cylinder 4, the outer ring 6 and the end plate 7, but an outer cylinder is provided instead of the outer ring 6 having an L-shaped cross section, and the end plate 7 is omitted.
- the vibration isolator according to the present invention can be suitably used, for example, for an application that is installed in a construction machine and suppresses engine vibration.
