On the cross-sectional plane perpendicular to the inner/outer tube axis, the cross-sectional plane center of circle of the center of two auxiliary holes of relatively establishing and urceolus, inner core is on same straight line in the rubber layer.
Described urceolus one end is designed with (be used for limiting or distinguish installation direction) boss, and on the cross-sectional plane perpendicular to the inner/outer tube axis, boss is symmetrical about the straight line at urceolus, place, the inner core cross-sectional plane center of circle; The inner core axis to the distance of boss greater than the distance of urceolus axis to boss.
Described inner core and urceolus are metallic framework.
Described inner core, urceolus do not overlap with the bonding posterior axis of the vulcanization of rubber, there is certain off-centre design, thereby when realizing normal vehicle operation, under the operator's compartment action of gravitation, operator's compartment is in and the ground level state after the rubber generation plastic deformation, to improve user's comfort.
Described rubber is contained within the closed region that is comprised of inner tank theca, outer tube inner wall and inner/outer tube both ends of the surface thereof fully.All be reserved with certain gap between rubber layer both ends of the surface and the inner/outer tube both ends of the surface, to guarantee not exceed the inner/outer tube both ends of the surface behind the rubber layer load metamorphism axial elongation.
Described two auxiliary holes are the through hole parallel with the axis of urceolus, inner core.The relative axis in two holes and establishing is distributed in the rubber layer of inner/outer tube axis both sides to (above-below direction) along main loading side.On the cross-sectional plane perpendicular to the inner/outer tube axis, the profile of auxiliary hole all adopts arc transition, to improve product force dispersion ability, eliminates the stress raisers phenomenon that occurs after the carrying.The shape of auxiliary hole profile on cross-sectional plane, size then are to set to the rigidity value of (above-below direction) according to main loading side.
Compared with prior art, the utility model is optimized product structure: increased the urceolus skeleton, the filled rubber volume is increased, cushioning performance is improved, increased simultaneously the area of contact of metallic framework and rubber layer, rubber is increased with the bind strength of metal piece.The utility model combines the main carrying situation when using in addition, in the rubber of filling, offer the auxiliary hole of special shape, what overcome that front overhang damper mechanism in the past occurs causes the defectives such as rubber cracking, conquassation because of stress raisers in the load bearing process, prolonged the service life of mechanism.Offer simultaneously auxiliary hole, vibration damping, sound insulation and the cushion characteristic of mechanism are further enhanced.
