Description
Technical field
The invention belongs to automotive engineering field more particularly to a kind of torsion beams.
Background technique
Torsion beam rear axle is one kind of automobile axle type, is the jump up and down that left and right wheels are balanced by a torsion beam
It is dynamic, reduce rocking for vehicle, keeps the steady of vehicle.When a sidecar wheel moves up and down, torsion beam can be made to beat, thus
It drives other side wheel also correspondingly to beat, reduces the inclination of entire vehicle body or rock.Since its own is with certain torsion
Rigidity, can play the role of identical with stabilizer bar, can increase the roll stiffness of vehicle, improve the roll stable of vehicle
Property.The features such as torsion beam suspension structure is simple, easy I& M, is widely used on family-sized car.After torsion beam
The core of bridge is that the structure of girder designs, and girder bears main back axle load, at present the torsion suspension application of top load intensity
The main reason for cannot promoting is that the intensity of girder cannot be guaranteed, and the girder used now is straight section crossbeam mostly, this
Girder intensity difference is easy cracking, and the bonding strength of girder and trailing arm is poor, and connection reliability is poor.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, provides a kind of torsion beam rear axle assembly, by redesigning stringer
Shape reinforce the bond strength of stringer and girder and the intensity of stringer itself, guarantee the stabilization of stringer and girder and whole
Body anti-twisting property guarantees that elastic deformation is concentrated mainly on girder, damage caused by avoiding stringer stress excessive, while in girder
Increase the strength and stiffness that stabiliser bar guarantees girder.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of torsion beam rear axle is total
At, including girder, the girder two sides are provided with stringer, and the girder is U-shaped to have a U-type groove, two in the U-type groove
End is respectively arranged with the sleeve being bolted, and stabiliser bar is connected between sleeve described in two, the stringer is for it
Font, the stringer includes front tube, swan-neck and rear pipe, the front tube, the swan-neck and the rear Guan Yiti
Molding, the front tube and the rear Guan Pinghang, the front tube to the swan-neck interface perimeter gradually increases, described
Swan-neck to the rear area within a jurisdiction face perimeter be gradually reduced, the rear area within a jurisdiction face perimeter is longer than front tube interface perimeter,
The girder is fixed on the swan-neck.
In above-mentioned technical proposal, it is preferred that it is provided in the U-type groove and matches fixed lobe with the sleeve, institute
The through-hole matched with the bolt is provided on the fixed lobe stated.
In above-mentioned technical proposal, it is preferred that the stabiliser bar is fixed by welding with the sleeve, the stabiliser bar
On weld seam do bead.
In above-mentioned technical proposal, it is preferred that the girder is domed.
In above-mentioned technical proposal, it is preferred that the stabiliser bar includes cross bar and the brace that the cross bar two sides are arranged in,
The brace connection sleeve, the angle between the cross bar and the brace is obtuse angle.
In above-mentioned technical proposal, it is preferred that the stringer is made of punching press, has punching press seam, institute on the stringer
The punching press seam welding filling stated.
In above-mentioned technical proposal, it is preferred that any section interface of the stringer is all round rectangle.
In above-mentioned technical proposal, it is preferred that the front tube is connected with lining pipe, and the rear pipe is connected with wheel branch
Frame.
In above-mentioned technical proposal, it is preferred that the rear area within a jurisdiction face perimeter length is front tube interface perimeter length
1.5 again.
In above-mentioned technical proposal, it is preferred that the part that the girder two sides are connect with the swan-neck is arc-shaped.
Existing torsion beam middle girder and the molding manufacture of stringer non-integral, need additional welded connecting, are that dependent is outstanding
Hanging hang structure is simple, and cost is relatively low, therefore is mainly used in small, minicar.In use about torsion beam off-axis, stringer with
The problem of girder fracture, is continuous, this main cause is girder intensity difference, girder and stringer bonding strength is poor and girder too leans on
Unbalance stress caused by nearly axis wheel position.Due to cost and space factor, girder in most of torsion beams very close to
Axis wheel, torsion beam is non-rigid, needs whole torsion to a certain extent, and existing shaped torsion beam girder is closer to wheel
Axle center, the elastic deformation that girder is subject to is smaller, because structure middle girder thus is more by vertical power, elasticity when such case
Deformation is mostly transmitted to stringer, causes stringer stress excessive, often results in the fracture of stringer.In the present invention, it mainly has modified
Stringer designs are both zig-zag type by the structure of stringer, and the front and rear tube of stringer is parallel, and front and rear tube is connected by swan-neck
Connect, and any section interface of this three is all round rectangle, interface perimeter from small to large, again from big to small, girder and stringer
At swan-neck, swan-neck is extend into girder for junction, so when stressed, due to stringer moulding and with the company of girder
Position is connect, main torsion is born by girder, then elastic module is uniformly distributed in entire torsion beam by girder, makes winner
Beam and stringer junction are in balance always, avoid excessive power from destroying overall structure, while reducing the stress of stringer, in order to protect
The intensity and elastic module of girder are demonstrate,proved, while stabiliser bar is also set in girder, guarantees the torsional stabilizer of girder by stabiliser bar.
Compared with prior art, the beneficial effects of the present invention are: by redesign stringer shape come reinforce stringer with
The bond strength of girder and the intensity of stringer itself guarantee the stabilization and entirety anti-twisting property of stringer and girder, guarantee bullet
Property deformation be concentrated mainly on girder, damage caused by avoiding stringer stress excessive, at the same in girder increase stabiliser bar guarantee master
The strength and stiffness of beam.
