Summary of the invention
In order to address the above problem, the invention discloses a kind of Control arm bush structure, comprise: Control arm body, outer liner tube, rubber, internal lining pipe, bolt and nut, outer liner tube is by press-fiting interference fit, be fixed in the Control arm body, rubber links into an integrated entity outer liner tube and internal lining pipe, and two end faces of internal lining pipe are the inclined-planes.
Further, also comprise slide block, be enclosed within on the body of bolt of bolt, can in the mating holes of vehicle body, slide, before internal lining pipe is assembled to vehicle body, slide block is shifted out mating holes, can in assembling, create tolerance clearance for internal lining pipe.The face that slide block cooperates with the end inclined-plane of internal lining pipe also is the inclined-plane.Have boss on the slide block, guide-localization and restriction slide block rotate in mating holes when being used to install.
Further, the sulfuration by rubber links into an integrated entity outer liner tube and internal lining pipe.
The constraint number that the present invention adopts two groups of inclined-planes to fit in is 5, have more 2 constraints than the plane cooperation, utilize this point, the present invention changes fit system in the past, the constraint number that has more can guarantee to cooperate more firmly, solved effectively in being connected of Control arm gum cover internal lining pipe and vehicle body (vehicle frame, drg) because Bolt Torque loss or fitting surface slide relative cause bolt fracture, and can satisfy assembling with angle installation requirement; The design of the mobility of slide block can strengthen tolerance clearance in addition, makes assembling become more simple and easy, and the fitting surface that assembles is no longer needed high working accuracy, thereby tooling cost is reduced.

The specific embodiment
In conjunction with the accompanying drawings, below further in detail explanation the present invention design be how to solve many not enough problems in the present Control arm lining.
Referring to Fig. 1,2, Control arm bush structure disclosed by the invention comprises: Control arm body 7, outer liner tube 14, rubber 13, internal lining pipe 12, bolt 1, nut 11 and slide block 6.At first outer liner tube 14 is by press-fiting interference fit, be fixed on the Control arm body 7, sulfuration by rubber 13 links into an integrated entity outer liner tube 14 and internal lining pipe 12 again, two end faces of internal lining pipe 12 are inclined-planes 10, two the end inclined-plane 10 respectively with vehicle body (vehicle frame, drg) inclined-plane of the inclined-plane of upper nut 11 ends and other end slide block 6 ends cooperates, combination by bolt 1 and nut 11, urgent moment, make the inclined-plane and the vehicle body (vehicle frame of slide block 6, drg) 5 inclined-plane compresses two end inclined-planes 10 of internal lining pipe 12 respectively, make it fixing, Control arm body 7 is just by outer liner tube 14 like this, rubber 13, internal lining pipe 12, bolt 1, nut 11 and slide block 6 are connected to vehicle body (vehicle frame, drg) on 5.
Sketched the connection mechanism of total above, below emphasis say down that the present invention is the not enough problem that how to solve in the common connection.
Amount of constraint referring to the 10 pairs of internal lining pipes 12 in 1,2, two end inclined-plane is 5, if two planes cooperate, amount of constraint has only 3 so, and retraining number has like this increased by two, and fitting surface is under the compressing of bolt force, can easily guarantee not produce relative motion after the assembling, make cooperation more firm.The both ends of the surface that internal lining pipe 12 cooperates all are bevelleds, opposite planar has just directly limited relatively rotating between the fitting surface like this, because the axle of fitting surface normal and internal lining pipe is not on same line, there is certain angle in both, so just can not rotate; Because two end faces all are inclined-planes, have so also limited fitting surface and moved radially in addition along bushing pipe.In addition, a lot of automobile linings mainly only are subjected to diametral load external force, the direction of tilt of end face can be designed to and be subjected to force direction consistent for this situation, as shown in Figure 1, if the stressed radial level power that is mainly of lining, lining is being subjected to external force to do the time spent so, and fitting surface wedge more is tight more, so do not worry that relative motion is arranged between fitting surface.In addition, angle requires for being equipped with, and this structure can easily obtain, because can not produce relative rotation between this respective outer side edges face, so just guaranteed the uniqueness of angle of assembling, make assembling after, lining does not exist internal stress, the service life of having improved lining under design point.
