- the weight and cost can be reduced and the size can be reduced, and it can be easily applied to a small construction machine.
- the ring-shaped elastic body 14 is provided between the vehicle body frame 11 and the bottom wall side member 12, and the load from the vehicle body frame 11 and the bottom wall side member 12 is applied in the compression direction of the ring-shaped elastic body 14.
- the ring-shaped elastic body 14 is not subjected to a load in the shearing direction, and even if an excessive load is applied to the ring-shaped elastic body 14, it is possible to prevent cracks from occurring.
- the vibration absorbing function due to the deformation of the ring-shaped elastic body 14 and the vibration damping function accompanying the movement of the damping plate 19 in the viscous liquid 17 can be provided, sufficient vibration damping performance can be ensured.
- both the compression direction load and the extraction direction load are bidirectional. Thus, excessive inclination of the bottom wall side member 12 with respect to the vehicle body frame 11 beyond a certain level can be suppressed.
- the body frame 11 as the flange member has higher rigidity than the rigidity of the case 16. Therefore, even if an excessive load is applied, the body frame 11 cannot be easily deformed. Further, the body frame 11 receives the compression direction load via the ring-shaped elastic body 14 and also receives the extraction direction load via the thick seal portion 22b of the seal member 22. The frame 11 receives and the case 16 is not overloaded.
- the flange member is a part of the body frame 11, the body frame 11 can be used as a strength member for the liquid-filled mount 10, and the number of parts constituting the liquid-filled mount 10 can be reduced. The weight of the mount 10 can be reduced and the size can be reduced.
- cylindrical elastic body 14d as the second elastic body is disposed between the inner peripheral surface of the hole 11a of the vehicle body frame 11 and the outer peripheral surface of the sleeve 21, the bottom wall side member 12 and the vehicle body
- the cylindrical elastic body 14d receives the load caused by the movement in the left and right direction and in the prying direction between the frame 11 and vibrates even in the lateral direction and in the prying direction between the bottom wall member 12 and the body frame 11. Absorption function can be added.
- the seal member 22 can be fixed to the sleeve 21 in advance, so that the assembly operation of the liquid-filled mount 10 is performed. Can be made easier.
- the ring-shaped elastic body 14 and the seal member 22 are pre-compressed under the assembled state of the liquid-filled mount 10, so that the pre-compressed ring-shaped elastic body 14 and the seal member 22 generate a high frequency. Fine vibrations can be effectively absorbed, and therefore transmission of high-frequency fine vibrations to the bottom wall side member 12 can be effectively insulated.
- the member on one side can be the bottom wall side member 12 of the cap in the construction machine, and the member on the other side can be the body frame 11 in the construction machine.
- the liquid-filled mount 10 can be used as a construction machine or the like.
- the body frame 11 in the industrial machine can be used as a strength member.
- the liquid-filled mount 10 is assembled to the vibration damping body 13 constituting the liquid-filled mount 10, the first step of assembling the vibration-damping body 13, and the bottom wall side member 12 by attaching the vibration damping body 13 to the vehicle body frame 11. Assembling the bottom wall side member 12 and the body frame 11 through the second step of assembling the ring-shaped elastic body 14 constituting the liquid-filled mount 10 between the body frame 11 and the body frame 11 Can Therefore, since the vibration damping body 13 and the ring-shaped elastic body 14 are assembled separately, for example, a ring having a different spring constant depending on the magnitude of the load on the side wall member 12 side force, the driver's preference, etc. It is possible to change to the elastic body 14 or to easily replace the vibration damping body 13 and to improve the tuning and maintenance of the liquid-filled mount 10.
- annular convex portion 16c protruding inward in the direction of reducing the inner diameter of the case 16 serves as a pressurizing means such as press working. Therefore, it is formed.
- the seal member 22 is formed with an annular recess 22d on the outer peripheral side of the thick seal portion 22b of the seal member 22 so as to be opposed to the annular projection 16c of the case 16 and into which the annular projection 16c enters. Note that the plate member 23 is abolished in preparation for the embodiment shown in FIGS. 1 to 4 described above.
- the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
- the force showing rubber made of rubber as the elastic body is not limited to this, and instead of a rubber elastic body, a coil spring is provided so as to surround the periphery of the stud. Also good.
- the flange member and the other member are the same, that is, the vehicle body frame 11 has a structure serving as both the flange member and the other member.
- the present invention is not limited to this, and the vehicle body frame 11 and the flange member are Each of them may be composed of separate members.
- the stud according to the present invention includes the bolt 18 and the sleeve 21.
- the present invention is not limited to this, and the stud is not limited to this.
- it is a member that connects the member on the side and the attenuation plate, its component parts and shape are not limited.
- the ring-shaped elastic body 14 constituting a part of the liquid-filled mount 10 is incorporated between the vehicle body frame 11 and the bottom wall side member 12.
- the present invention is not limited to this, and other independent elastic bodies (rubber bowls) are arranged in line with the ring-shaped elastic body 14 according to the difference in weight on the bottom wall side member 12 side or the driver's preference. It is also possible to adjust the spring constant by incorporating a sex body or coil spring).
- the thin-walled portion 14c of the ring-shaped elastic body 14 is provided on the outer peripheral side of the ring-shaped elastic body 14, but the present invention is not limited to this, and the ring-shaped elastic body 14 is not limited to this. It is important to provide a thin portion at the inner peripheral side of the elastic body 14 or at the intermediate portion between the outer peripheral side and the inner peripheral side of the ring-shaped elastic body 14.
- the thin-walled portion may be provided so that the contact area of the ring-shaped elastic body 14 increases in accordance with the proximity of the ring-shaped elastic body 14, that is, the spring constant of the ring-shaped elastic body 14 increases.
- the ring-shaped elastic body 14 and the seal member 22 are shown as those made of a rubber material.
- the present invention is not limited to this, and other rubber materials are used.
- the elastomer material can also be a metal spring.
- rubber materials and elastomer materials are particularly preferable because of their internal damping and light weight.
- the liquid-filled mount is mounted between a body frame and a cab (driver's cab) in a construction machine such as a power shovel, and is used to absorb vibration transmitted to the cab.
