Abstract
The utility model proposes a kind of automobile control arm lining, be made up of inner metal tube, rubber and intermetallic metal skeleton.Rubber coating and the sulfuration of intermetallic metal skeleton are integrated, and are attached to outside inner metal tube by sulfuration.Owing to increasing intermetallic metal skeleton, this bush structure can provide higher radial rigidity under lower rubber hardness condition, and axial stiffness recruitment is less, thus provides good lining performance perameter, promote traveling comfort and the handling of car load, meet the demand of vehicle performance.
Description
Technical field
the utility model belongs to automotive suspension chassis part technical field, is specifically related to Control arm bush structure.
Background technology
Control arm, as function unit important on automobile, has very important impact to the handling of car load and traveling comfort.The radical function of Control arm controls wheel trace, transmits transverse force, and the function of transmission, decay transverse force mainly born by Control arm lining in the structure of Control arm, and the rigidity of Control arm lining has very important effect to realizing this function.As described in Figure 1, it is formed primarily of inner metal tube 1 and rubber coating 2 existing Control arm lining, is attached on the outer wall of inner metal tube 1 by rubber coating 2 by sulfuration process.Lining rigidity becomes certain proportional relation with elastomeric material hardness, but is limited to the bad shortcoming of elastomeric material endurance quality, and lining hardness infinitely can not promote and meet rigidity requirement.Therefore, the lining of this structure, having significant limitation along the lifting capacity of inner metal tube 1 radial rigidity, can not meet the performance requriements of high radial rigidity.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile control arm bush structure, by increasing intermetallic metal skeleton in the middle of rubber coating, reducing the thickness of rubber coating, lining can be made to significantly improve in the rigidity of radial direction.
The Control arm bush structure that the utility model proposes is made up of inner metal tube, rubber and intermetallic metal skeleton.Rubber coating and the sulfuration of intermetallic metal skeleton are integrated, and are attached to outside inner metal tube by sulfuration.Owing to increasing intermetallic metal skeleton, this bush structure can provide higher radial rigidity under lower rubber hardness condition, meets the demand of vehicle performance.
Further, intermetallic metal skeleton 3 is a sleeve-shaped, axially has multiple notch, is convenient to the both sides that rubber liquid can flow to intermetallic metal skeleton.
The advantage of this Control arm bush structure can provide very high radial rigidity under lower rubber hardness condition, and axial stiffness recruitment is less, thus provide good lining performance perameter, promotes traveling comfort and the handling of car load.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing Control arm lining;
Fig. 2 is the structural representation of Control arm lining of the present utility model;
Fig. 3 is the structural representation of intermetallic metal skeleton.
Detailed description of the invention
Structure of the present utility model is described in detail below in conjunction with accompanying drawing:
With reference to figure 2, this Control arm bush structure is made up of inner metal tube 1, rubber coating 2 and intermetallic metal skeleton 3.Rubber coating 2 and intermetallic metal skeleton 3 sulfuration are integrated, and are attached to outside inner metal tube 1 by sulfuration.
See Fig. 3, intermetallic metal skeleton 3 is cylindrical shape, and its upper and lower two ends have 4 symmetrical non-through grooves 4.During making, inner metal tube 1 and intermetallic metal skeleton 3 are fixed in vulcanization of rubber mould, wherein inner metal tube 1, rubber coating 2 and intermetallic metal skeleton 3 form an overall lining by sulfuration process is capable, and the groove 4 on intermetallic metal skeleton 3 is convenient to the both sides that rubber liquid can flow to intermetallic metal skeleton 3.The length and width size of groove 4 is larger, the increase that the axial stiffness of lining also can be suitable.When needs increase lining radial rigidity, will increase the diameter of intermetallic metal skeleton 3, the rubber outside intermetallic metal skeleton 3 is reduced, the compress variation reducing rubber significantly improves lining radial rigidity.
