Abstract
The invention relates to a rubber bushing structure for an automotive suspension. The rubber bushing structure comprises a ball stud outer seat and a ball casing pipe. The outer portion of the ball stud outer seat is provided with the cylindrical outer surface. The cylindrical inner surface is arranged inside the ball stud outer seat. The cylindrical outer surface of the ball stud outer seat is sleeved with a rubber bushing body, and an outer bushing casing pipe is arranged outside the rubber bushing body. A center through hole structure is formed in the axial direction of the ball casing pipe. A spherical surface structure is arranged in the middle of the ball casing pipe. The two ends of the spherical surface structure are of a cylinder structure. The spherical surface structure is installed on the cylindrical inner surface of the ball stud outer seat. As the ball structure is introduced in the rubber bushing structure, the ball casing pipe of the bushing and a rubber body can relatively rotate and swing freely, swing and torsion counterforce generated by a currently used ordinary rubber bushing in the movement process of the suspension can be eliminated, influence on the suspension stiffness from the bushing is reduced, movement lagging of a suspension system is reduced, and the comfort level and controllability of a whole automobile are improved.

Detailed description of the invention
Below with reference to specific embodiments and the drawings, automotive suspension of the present invention is described in further detail with rubber bush structure.
Embodiment 1
As shown in Figure 1, automotive suspension bush structure described in the present embodiment, it comprises lining outer tube (1), rubber bush body (2), the outer seat of ball end (3), non-metal bulb liner (4), bulb sleeve pipe (5), ball end dust boot (6) (7); Described bulb sleeve pipe (5) has center hole (5a), left side (5b) and right side (5c); Bulb sleeve pipe (5) sphere (5d) outside is wrapped up by non-metal bulb liner (4), non-metal bulb liner (4) riveting is in ball-stud socket (3), ball-stud socket (3) is connected with rubber bush body (2) sulfuration, and rubber bush body (2) is connected with lining outer tube (1) sulfuration; Ball end dust boot (6) (7) end face (6b) is (7b) (3b) bonding with ball end outer seat end face (3a) respectively, ball end dust boot (6) (7) outer end inner sealing surface (6c) (7c) (5e) contacts with bulb sleeve pipe (5) face of cylinder (5f), inner sealing grease, for non-metal bulb liner (4) and bulb sleeve pipe (5) sphere-contact place provide lubricated.When assembling, bulb sleeve pipe (5) is coaxially installed with subframe mounting hole, ball end dust boot (6) (7) end face (6a) (7a) is fitted with subframe panel beating face, by bolt and nut, bulb sleeve pipe (5) is clamped, signal is installed as shown in accompanying drawing 4 and Fig. 5.
Automobile bushing rubber body described in the present embodiment has general suspension swing arm, leverage rubber bush body shape structure, for isolating the high-frequency vibration that reaches vehicle body from road surface, absorbs the impact of road surface to suspension, ensures certain travelling comfort; And inner contained ball end structure can improve movement accuracy, eliminate swing and torsion counter-force that current General Purpose Rubber lining used produces, reduce suspension system motion sluggish, improve car load traveling comfort and handling.Because lining only produces compressive deformation, there is no shear deformation, can improve lining service life.When vehicle is after certain travelled distance, because tie bolt, nut predetermincd tension reduce, the twisting resistance that conventional bushings produces along axis direction will cause the fitting surfaces such as lining inner sleeve and subframe to produce relative rotation, the progressive bolt pretightening that reduces, make to be suspended in and while being hit, produce abnormal sound, when serious, can make binding bolt, nut get loose, suspension lining can reduce this risk to a great extent described in the present embodiment.
In a word, suspension bush structure advantage of the present invention is not sacrifice and under car load travelling comfort prerequisite, promotes suspension moving characteristics accuracy, car load manipulation ability and lining service life.
For the ordinary skill in the art; specific embodiment of the present invention is just exemplarily described the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
