The utility model solves the technical problems by adopting the following technical scheme:
The utility model provides an automobile control arm bush, includes the outer lane and inlays the interior lining barrel in the outer lane, the outer lane with interior lining barrel interference fit, the rubber body inlays and is in the lining barrel and the rubber body suit is in the inner circle is outside the internal inlaying of rubber is equipped with a plurality of elastic metal pieces, the elastic metal piece is bow-shaped its towards the inner circle axis direction arch, works as the inner circle makes after to the single side extrusion of outer lane elastic metal piece warp and then absorbs impact and resume after buffering, effectually improved the support intensity of the rubber body to when the aggravation holding power of deformation is stronger.
Preferably, a gasket is embedded between the inner lining cylinder and the end part of the elastic metal sheet, the inner lining cylinder can provide supporting force for the end part of the elastic metal sheet under the action of the gasket, and the elastic metal sheet is stressed to deform for auxiliary support after the inner lining cylinder is extruded on one side of the rubber body.
Preferably, the inner walls of the two ends of the lining cylinder are provided with arc-shaped annular grooves, the outer side surfaces of the two ends of the elastic metal sheet are provided with arc-shaped bayonets, and a spring ring is embedded between the annular grooves of the lining cylinder and the arc-shaped bayonets.
Preferably, chamfer structures are arranged at two ends of the inner ring of the rubber body, so that the flaring is convenient to realize sliding sleeving during installation.
Preferably, the rubber body is provided with jacks at intervals in an annular mode, the elastic metal sheets are inserted into the jacks, and the distance between the adjacent jacks is consistent with the width of the jacks.
Preferably, the thickness of the elastic metal sheet is between five and eight millimeters, and the width of the elastic metal sheet is not more than two centimeters.
The utility model has the advantages and positive effects that: the strength of the rubber body is effectively supported through the skeleton structure formed by the embedded elastic metal sheets, the two ends of the elastic metal sheets act on the lining cylinder through the spring rings to realize strong support, and the elastic metal sheets can absorb impact and release impact energy due to the metal structure, so that the service life of the rubber body is effectively prolonged.
