Problems solved by technology

Therefore, it is necessary to use a large-capacity punch to machine the brakes 28, 29, and the manufacturing scale of the anti-vibration support device becomes large, and the manufacturing cost is likely to increase.
In the case where the thickness of the sheet material used to manufacture the stoppers 28 and 29 is large, it may not be possible to manufacture the bowl-shaped stoppers 28 and 29 by such punching.

Embodiment Construction

[0026] Next, preferred embodiments for implementing the anti-vibration support device of the present invention will be described with reference to the drawings.

[0027] figure 1 It is a figure which shows the 1st embodiment of the anti-vibration support apparatus of this invention, (a) figure is a front view, (b) figure is A cross-sectional view of (a) figure, (c) figure is B cross-sectional view of (a) figure .

[0028] The anti-vibration support device of the first embodiment is a device used when the engine 1 is mounted on a vehicle body (rotation) frame in a construction machine such as a hydraulic excavator, such as figure 1 As shown in (a) and (b), the anti-vibration support device includes: a mounting part 1a to be installed on an anti-vibration object such as an engine 1, and a rubber body that absorbs the vibration of the engine 1 in the vertical direction and the horizontal direction. The support of the elastic member that constitutes etc., for example rubber su...

Abstract

A vibration-damping support device occupies a less installation space. The vibration-damping support device has a rubber mount (2) which is fitted to a mounting section (1a) for mounting thereon an object, such as an engine (1) vibrating in the vertical and horizontal directions, mounted on a hydraulic excavator and to be isolated from vibration and which has an elastic member made of rubber or the like for absorbing vibration of the engine (1); a support bracket (3) which is fixed to a support member, such as a rotating frame (not shown), for supporting the rubber mount (2); and stoppers (8,9) which are mounted integrally on the support bracket (3) and prevent excessive deformation of the elastic member of the rubber mount (2) caused by vibration of the engine (1). The stopper (8) is placed above the support bracket (3), and the stopper (9) is placed below the support bracket (3). The stoppers (8, 9) are constructed from plate-like members (8a, 8b, 9a, 9b) having a circular arc-shape in a plan view.

Description

technical field [0001] The present invention relates to an anti-vibration support device effectively used for anti-vibration supports of engines of construction machines and the like. Background technique [0002] As such a prior art, there is a technique disclosed in Patent Document 1. Figure 4 It is a figure which shows the prior art substantially the same as the anti-vibration support apparatus shown in this patent document 1, (a) figure is a front view, (b) figure is F cross-sectional view of (a) figure. [0003] Should Figure 4 The prior art shown is an engine anti-vibration support device installed on a machine that vibrates strongly in the vertical direction, such as a construction machine. This engine anti-vibration supporting device is provided with: the installation part 21a that is installed on the anti-vibration target object, i.e. the engine 21, the rubber bracket 22 provided with the elastic member 22a that absorbs the vertical direction of the engine 21, and...
