Description

Elastic hinge
Technical field
The utility model is about a kind of link, specifically about a kind of elastic hinge.
Background technique
Elastic hinge is widely used in the production industry of automobile, and elastic hinge is the vitals that connects automotive suspension and vehicle body, and its major function is: 1) flexibly connect suspension system and vehicle body; 2) transmit various power and the moment that suspension acts on vehicle body; 3) attenuation vibration and impact.The performance quality of elastic hinge directly influences riding comfort, control stability and the Security of automobile.
As shown in Figure 1, traditional elastic hinge comprises the rubber bushing 3 between steel bushing 1 in the ring, ring outer steel sleeve 2 and sulfuration outer steel sleeve.Adopt traditional elastic hinge, will reach the riding comfort of car load on the one hand, require to adopt softer rubber bushing, slow down the impact that wheel transmits; To accomplish the accurate guiding of wheel on the other hand, satisfy the maneuverability of car load, require to adopt have certain rigidity than ebonite bush, therefore, adopt traditional elastic hinge to be difficult to take into account simultaneously the riding comfort and the control stability of car load, especially traditional elastic hinge is used for the trailing arm torsion beam suspension, under lateral forces, because the elastic reaction of rubber, the trailing arm torsion beam can produce the wheel axle steering effect that is unfavorable for control stability, cause the wheel oversteering, influence travel safety.
The model utility content
The purpose of this utility model is to overcome traditional elastic hinge can not satisfy the riding comfort of car load and the shortcoming of control stability, can satisfy riding comfort thereby provide a kind of, can satisfy the elastic hinge of control stability again.
Elastic hinge of the present utility model comprises interior cover, lining and overcoat, lining is between interior cover and overcoat, and fit with the internal surface of the outer surface of interior cover and overcoat, wherein, on the Cylindrical object outer surface of interior cover projection and convex edge are arranged, projection is the symmetry axis symmetric arrangement with the central axis of interior cover, and the convex edge is positioned at an end of cover column external surface; Curve bath and groove are arranged on the described lining, and curve bath is positioned on the end face of lining one end, and is the symmetry axis symmetric arrangement with the lining central axis, and groove is positioned at the curve bath both sides, and communicates with curve bath.
The utility model elastic hinge is compared with original structure, do not increase under the prerequisite in number of spare parts, by improvement to the elastic hinge internal structure, when making elastic hinge be used for the trailing arm torsion beam suspension, even under the effect of lateral force, because the lateral rigidity under this orientation angles and the effect of radial rigidity can be improved in projection and convex edge, avoided the trailing arm torsion beam can produce the wheel axle steering effect that is unfavorable for control stability, cause the wheel oversteering, influence travel safety, simultaneously, owing on the lining curve bath and groove are arranged, the impact force to vehicle body that this structure is produced by ditch the time wheel leaves the space of buffering, therefore, employing the utility model elastic hinge can satisfy the requirement of riding comfort, can suppress the axle steer effect of trailing arm torsion beam again, prevent that wheel steering is excessive, improve control stability and Security.
Description of drawings
Fig. 1 is a traditional elastic articulated elements structural representation;
Fig. 2 has the end-face structure schematic representation of curve bath for the utility model elastic hinge;
Fig. 3 is that the utility model elastic hinge is along the longitudinal axis generalized section;
Fig. 4 is that the utility model elastic hinge is along the horizontal axis generalized section;
Fig. 5 is the scheme of installation of the utility model elastic hinge in the trailing arm torsion beam suspension.
Embodiment
Below in conjunction with accompanying drawing preferred implementation of the present utility model is elaborated.
Shown in Fig. 2-4, cover 4, lining 5 and overcoat 6 in elastic hinge of the present utility model comprises, lining 5 is between interior cover 4 and overcoat 6, and fit with the internal surface of the outer surface of interior cover 4 and overcoat 6, wherein, on the Cylindrical object outer surface of interior cover 4 projection 10 and convex edge 11 are arranged, projection 10 is the symmetry axis symmetric arrangement with interior cover 4 central axis, and convex edge 11 is positioned at an end of cover 4 Cylindrical object outer surfaces; Curve bath 8 and groove 13 are arranged on the described lining 5, and curve bath 8 is positioned on the end face of lining 5 one ends, and is the symmetry axis symmetric arrangement with lining 5 central axis, and groove 13 is positioned at curve bath 8 both sides, and communicates with curve bath 8.
Cover 4 has a central through bore 7 in described, this through hole 7 is to be used for elastic hinge 18 is fixedly connected on mounting hole on the body overhang connecting base 17, on the Cylindrical object outer surface of interior cover 4 projection 10 and convex edge 11 are arranged, projection 10 is rectangular blocks, projection 10 and convex edge 11 can make vehicle bear under the lateral force operating mode in turning, improve lateral rigidity and radial rigidity under this orientation angles, the axle steer problem of avoiding the trailing arm torsion beam suspension to occur, prevent that wheel steering is excessive, improve Security.
Curve bath 8 and groove 13 are arranged on the described lining 5, to the impact force of vehicle body, improve riding comfort when the interaction energy of curve bath 8 and groove 13 effectively relaxes wheel by ditch; Also fluted 12 on the lining 5, groove 12 cooperates with projection 10, and groove 12 is identical with the number of projection 10.Under the preferable case, lining 5 is a vulcanized rubber.
Described overcoat 6 can be existing normally used jacket structure, and the internal surface of overcoat 6 is smooth cylindrical hole 9, and the outer surface of overcoat 6 is smooth cylindrical.
