The rubber vibration isolator of general type can only ensure the effectiveness in vibration suppression in one or two directions, is difficult to the effectiveness in vibration suppression simultaneously taking into account three directions.As everyone knows, the harm of the vibration of substantially horizontal is very large, such as, in the low frequency large-amplitude sloshing situation of operator cabin, driver is easy obtains the occupation disease such as spine malformation, stomach trouble, so good vibration isolator not merely ensures the vibration isolating effect of Vertical direction, simultaneously also must the vibration in level of isolation direction.
Summary of the invention
The object of the invention is to the vibration in effective level of isolation direction, taken into account the vibration isolating effect in three directions simultaneously, reduce the center of gravity treating isolation mounting as far as possible.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of triangle firm support formula vibration isolator, is characterized in that: comprise metal support structure, rubber vibration isolation original paper, metallic support sleeve;
Metal support structure is one-body molded by three support arms, and overall in Y type, three support arm head ends intersect at a central point, and end circumferentially; End holds described rubber vibration isolation original paper;
Rubber vibration isolation original paper inside accommodates described metallic support sleeve;
Described rubber vibration isolation original paper is connected shaping with described metal support structure and described metallic support sleeve by vulcanization.
Metal support structure has certain depression around the upper and lower surface of support arm of central point.
Support arm end has the macropore of the described rubber vibration isolation original paper of an accommodation.
Rubber vibration isolation original paper is a pillar buoy, and the inside of cylinder has a uncovered hole of matching with the metallic support sleeve-shaped that it holds, and the two ends that the outer wall of cylinder is positioned at support arm end macropore are outward-dipping.
Rubber vibration isolation original paper is arranged in the macropore of support arm end, and one end protrudes from the surface of support arm, and this projection is reduced to the end face of projection gradually by the surface of support arm.
Metallic support sleeve is arranged in the uncovered hole of rubber vibration isolation original paper, and metallic support sleeve inner has an attachment hole.
One end barrel that metallic support sleeve is positioned at projection inside thickeies.
Three support arm ends are circumferentially uniformly distributed, and make three support arms form 120 degree of angles each other.
Angle between three rubber vibration isolation original papers that support arm is arranged and metallic support sleeve is 120 degree.
The support arm of metal support structure is also provided with installation through hole.
There is certain depression metal support structure upper and lower surfaces, and the size of depression is determined by born weight and Vibration Condition thereof;
In metal support structure, three support arm structures are not necessarily the same, according to the rigidity requirement of substantially horizontal in actual conditions, suitably can change its inner metallic support sleeve of accommodation and structure of rubber original paper;
The angle that vibration isolator is put determines according to the Vibration Condition in the substantially horizontal of two, all around, and suitable carrying out adjusts, the vibration better on level of isolation direction.
Beneficial effect of the present invention is:
The present invention utilizes the stability characteristic (quality) of three-support, compared with a bolted mode, adds the steadiness of the strong point, utilizes the effect of three main vibration isolation original paper elastic buffers, can rock the low frequency in effective level of isolation direction; Operator cabin supports with the depression of triangle metal support structure by bolt tightening, and more traditional vibration isolator, can reduce the height of C.G. of operator cabin, and this depression plays again draw-in groove effect simultaneously, can prevent the play of cab supporting structure; Main vibration isolation part due to vibration isolator of the present invention is that when ensureing that vertical stiffness is the same, can regulate respective horizontal rigidity respectively, namely horizontal rigidity adjustable extent of the present invention is wider by three cylinder type V" isolator isolation compositions.
