Abstract
The present invention proposes a kind of connection bush structure of twist beam-type rear suspension, it comprises internal lining pipe and outer liner tube, fill and be bonded with elastomeric material in the axial annulus between inside and outside bushing pipe, between the flange of the flange of internal lining pipe and outer liner tube, the flat rubber packing ring is set, the flange of flat rubber packing ring and outer liner tube is adhesively fixed, and and the flange of described internal lining pipe between have the gap.The present invention is by removing with axial elastomeric material one and thicker flange between outer liner tube flange in will be, change into and use the flat rubber packing ring, gap smaller between the outer liner tube flange in making, when automobile turning travels, the very fast disappearance in gap between flat rubber packing ring and the internal lining pipe flange, lining Z increases rapidly to torsional stiffness to line rigidity, X and Y, but can keep Z constant to line rigidity again simultaneously to torsional stiffness, X and Y, can improve road-holding property and ride comfort simultaneously, and it is stressed to improve the lining elastomeric material, helps improving lining service life.
Description
Technical field
The invention belongs to the rear overhang rack systems technology, be specifically related to the bush structure that is connected that uses in the installation of twist beam-type rear suspension and body contact.
Background technology
The car rear suspension extensively adopts twist beam-type rear suspension, twist beam-type rear suspension is by bush Assembly and body contact, have guiding and vibration isolation effect, bear all power and moment except that spring force and shock absorber power, the road-holding property of automobile, ride comfort and rubber bush are had bigger influence service life; In addition, the structure design of bush Assembly relates to rubber bush itself and other functions of use and production technology, thereby influences its cost.
The rigidity that twist beam-type rear suspension connects lining comprises the torsional stiffness of the line rigidity of X, Y, three directions of Z and X, Y, three directions of Z.Lining rigidity depends primarily on elastomeric material characteristic, lining shape and structure.Generally speaking, the rigidity of lining six direction is interactional, changes the rigidity of a direction, and the rigidity of other direction also can change, and promptly the rigidity of lining all directions intercouples.From improving the angle of road-holding property, wish to increase lining rigidity, from ride comfort with reduce the stressed angle of lining, wish to reduce lining rigidity.The contriver find that Z is bigger to the road-holding property influence to torsional stiffness to line rigidity, X and Y, and Z is bigger to the ride comfort influence to line rigidity to torsional stiffness, X and Y by analyzing.Existing bush Assembly structure is seen Fig. 1 and Fig. 2, it comprises outer liner tube 1 and the internal lining pipe 3 that is sleeved on together, in, the same end of outer liner tube respectively has a flange 5 and 6, between interior outer liner tube, fill and adhesive rubber material 2, elastomeric material is flange between internal lining pipe flange and outer liner tube flange, the flange of this rubber and internal lining pipe flange and outer liner tube flange closely bond, adopt the lining of this structure, elastomeric material is axially, be connected to an integral body with interior outer liner tube in the radial direction, the suffered power of rear axle all is delivered on internal lining pipe and the vehicle body by the single-piece elastomeric material of lining, the rigidity of six direction or all big, all little, therefore can not satisfy simultaneously handling stability can with ride comfort preferably.
Summary of the invention
Deficiency at the prior art existence, the present invention proposes a kind of connection bush structure of twist beam-type rear suspension, this structure can eliminate Z to line rigidity, X and Y to torsional stiffness and Z to torsional stiffness, X and Y coupling to line rigidity, improving under twist beam-type rear suspension lateral stiffness and the torsional stiffness situation, reduced the rigidity of rubber bush all directions simultaneously, help vibration isolation, and it is stressed to reduce lining, improves the service life of lining.
Purpose of the present invention realizes by following technical scheme:
A kind of connection bush structure of twist beam-type rear suspension, it comprises internal lining pipe and outer liner tube, and outer liner tube is enclosed within outside the internal lining pipe, leaves annulus between the two, and inside and outside bushing pipe respectively has a flange at same end.Fill and be bonded with elastomeric material in the axial annulus between described inside and outside bushing pipe; Between the flange of the flange of described internal lining pipe and outer liner tube the flat rubber packing ring is set, the flange of described flat rubber packing ring and outer liner tube is adhesively fixed, and has the gap between the flange of described flat rubber packing ring and described internal lining pipe.
Described flat rubber packing ring is thinner than the thickness of the elastomeric material between the axial annulus that is filled in inside and outside lining pipe.
The present invention is by removing with axial elastomeric material one and thicker flange between outer liner tube flange in will be, change into and use thin one deck flat rubber packing ring, gap smaller between the outer liner tube flange in making, thereby make lining Z to rigidity and X, Y can significantly improve to torsional stiffness, and the rubber rigidity between simultaneously interior outer liner tube cylinder also can be done lessly.
Adopt said structure, eliminated lining Z to line rigidity, X and Y to torsional stiffness and Z to torsional stiffness, X and Y coupling to line rigidity, when automobile turning travels, the very fast disappearance in gap between flat rubber packing ring and the internal lining pipe flange, bush Assembly Z increases rapidly to torsional stiffness to line rigidity, X and Y, but can keep bush Assembly Z constant to line rigidity again simultaneously to torsional stiffness, X and Y, can improve road-holding property and ride comfort simultaneously, it is stressed also can to improve the lining elastomeric material, helps improving lining service life.

Wherein, 1-outer liner tube, 2-elastomeric material, 3-internal lining pipe, 4-flat rubber packing ring, 5-outer liner tube flange, 6-internal lining pipe flange
The specific embodiment
Referring to Fig. 3, Fig. 4, this twist beam-type rear suspension connects lining and is made of internal lining pipe 3, outer liner tube 1, elastomeric material 2 and plane rubber cradle 4.Wherein outer liner tube 1 is enclosed within outside the internal lining pipe 3, and the interior filling of the axial annulus between two bushing pipes also is bonded with elastomeric material 2, and promptly elastomeric material 2 is not having flange, and its length only is confined between the face of cylinder of internal lining pipe 3 and outer liner tube 1.Between internal lining pipe flange 6 and outer liner tube flange 5 flat rubber packing ring 4 is set then, 4 on this flat rubber packing ring is bonding with outer liner tube flange 5, and retention gap then between the inboard of internal lining pipe flange 6.
During installation, after being installed on the base by bolt this lining, the internal lining pipe flange is in the base inboard, keeps a minim gap between internal lining pipe flange inboard and the rubber pad, the internal lining pipe flange outside keeps certain clearance with base, in order to avoid wear and tear in the working process.
