Preferably, described groove is two groups, comprises the first groove and the second groove, and described first groove and described second groove were placed in the both sides of vertical section of described rubber sleeve axis symmetrically.
Preferably, described first groove and described second groove are rectangular through slot.
Preferably, the edge, upper-end surface of described rubber sleeve and edge, lower end surface are equipped with hemisphere fillet.
Preferably, the upper-end surface of described metal-coating is provided with the first flange of outwards turnover, and the upper-end surface of described rubber sleeve is provided with second flange fixing with described first flange sulfuration.
Preferably, the lower end surface of described rubber sleeve is higher than the lower end surface of described inner metal sleeve.
The utility model provides a kind of novel mounting bush, and on the basis of existing lining, described rubber sleeve is provided with the groove that some groups run through its body in the axial direction, and described groove was placed in the both sides of vertical section of described rubber sleeve axis between two symmetrically; And the upper-end surface of described rubber sleeve is higher than the upper-end surface of described inner metal sleeve; Groove structure is set, rubber sleeve is made to be easy to deformation occurs, be beneficial to and improve the ability that mounting bush slows down impact, in addition, when rubber sleeve generation moderate finite deformation, the both sides sidewall that groove is relative can fit together, thus improves the rigidity of rubber sleeve, prevent the damage of rubber sleeve structure, also can ensure that mounting bush joint has good service behaviour; And by the upper-end surface of the upper end of rubber bushing higher than inner metal sleeve, to strengthen the deformability of rubber sleeve in axis, improve the bradyseism performance of its axis.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technological scheme of the prior art, being briefly described to the accompanying drawing used required in embodiment below, and will being described in further detail specific embodiment of the utility model by reference to the accompanying drawings, wherein:
Fig. 1 is the sectional view of mounting bush in prior art;
The sectional view of the mounting bush that Fig. 2 provides for the utility model embodiment.
Label declaration wherein in above-mentioned accompanying drawing is as follows:
1'-metal inner pipe, 2'-metal outer pipe, 3'-rubber;
1-metal-coating, 2-inner metal sleeve, 3-rubber sleeve;
11-first flange; 31-first groove, 32-second groove, 33-hemisphere fillet, 34-second flange.
Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with concrete enforcement, this programme is introduced further in detail.
With reference to figure 2, the mounting bush that the utility model provides, comprise metal-coating 1, inner metal sleeve 2 and the rubber sleeve 3 between described metal-coating 1 and described inner metal sleeve 2, three is sulfided into one, and, on described rubber sleeve 3, be provided with the groove that some groups run through its body in the axial direction, described groove was placed in the both sides of vertical section of described rubber sleeve 3 axis between two symmetrically; Groove structure is set, rubber sleeve is made to be easy to deformation occurs, be beneficial to and improve the ability that mounting bush slows down impact, in addition, when rubber sleeve generation moderate finite deformation, above-mentioned groove makes up rubber sleeve 3 and is out of shape the Volume Changes produced, and ensure that rubber sleeve 3 can not damage because space makes rubber inside produce extrusion-deformation not under certain stressing conditions; Simultaneously, during moderate finite deformation, the both sides sidewall that groove is relative can fit together, thus improves the rigidity of rubber sleeve, ensures that lining is spacing, mounting bush joint is made to have good service behaviour, such as, when described mounting bush is on subframe, due to when lining generation moderate finite deformation, rigidity improves, and can strengthen the smoothness of trailer reversing, stability and NVH performance.Further, arrange the upper-end surface of upper-end surface higher than described inner metal sleeve 2 of described rubber sleeve 3, enhance the deformability of rubber sleeve in axis, be beneficial to the bradyseism performance improving its axis.
Preferably, described groove is two groups, comprises the first groove 31 and the second groove 32, and described first groove 31 and described second groove 32 were placed in the both sides of vertical section of described rubber sleeve 3 axis symmetrically, facilitate the processing of lining, and effectively can ensure the intensity of lining.
Preferably, described rubber sleeve 3 is cylindrical bush, and described first groove 31 and described second groove 32 are positioned on the line of the same diameter of described rubber sleeve 3, ensures that rubber sleeve 3 stress deformation is symmetrical, provides service behaviour, easy to use.Certainly, described rubber sleeve 3 also can be the lining that cross section is the shape such as rectangle, ellipse.
In the present embodiment, described first groove 31 and described second groove 32 are all preferably rectangular through slot, convenient processing, and rubber sleeve 3 occur comparatively large deformation time, surface bonded to each other is comparatively large, is convenient to the adjustment of rigidity.
In order to prevent stress from concentrating, improve the working life of mounting bush, edge, upper-end surface and the edge, lower end surface of described rubber sleeve 3 are equipped with hemisphere fillet 33, and the diameter of described hemisphere fillet 33 can be 6mm.
