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 and stabiliser bar connection type, guarantee stringer and girder stabilization and whole anti-twisting property, guarantee elastic deformation
Be concentrated mainly on girder, damage caused by avoiding stringer stress excessive, while the stabiliser bar of girder guarantee girder intensity and
Rigidity.
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, it is characterized in that, the girder is V-shaped to have V-groove, the V
Both ends are respectively arranged with the connector being fixedly connected with stringer in type groove, are provided with stabiliser bar between two connectors, institute
The stringer stated is S type, and the stringer includes front tube, swan-neck and rear pipe, the front tube, the swan-neck and described
Pipe is integrally formed afterwards, and the front tube to the swan-neck interface perimeter gradually increases, and the swan-neck is to after described
Area within a jurisdiction face perimeter is gradually reduced, and the rear area within a jurisdiction face perimeter is longer than front tube interface perimeter, the girder and described
Connector is fixed on the swan-neck.
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.
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 be provided with spring base, the bullet between the girder and the stringer
Spring abutment is welded and fixed with the girder, the stringer respectively.
In above-mentioned technical proposal, it is preferred that the connector includes stabiliser bar link block and connect with the stabiliser bar
Block is in 90 ° of supporting block, and the supporting block includes the stringer stress piece mutually fixed with the stringer and two and the V-groove
The main beam stress piece that upper edge is mutually fixed.
In above-mentioned technical proposal, it is preferred that the stabiliser bar connection is block-shaped to match with the V-groove shape,
The stabiliser bar link block is provided centrally with the fixed hole matched with the stabiliser bar, and the stabiliser bar passes through welding side
Formula is fixed on fixed hole.
In above-mentioned technical proposal, it is preferred that the girder two sides are provided with the arc groove matched with the swan-neck.
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.Torsion beam is non-rigid, needs whole torsion to a certain extent, turns round to increase
Turn power, generally requiring to install stabiliser bar additional in girder also enhances girder, but the existing substantially fixed connection in stabiliser bar both ends
It is not the twisting resistance that the overwhelming majority is born by girder when twisting under this situation by force analysis on stringer,
Stringer has been also subjected to partial elastic deformation, thus in the present invention, mainly has modified the structure of stringer and the connection side of stabiliser bar
Formula guarantees the service life of the high intensity of girder, high life and torsion beam entirety.It is S type by stringer designs, front and rear tube passes through
Swan-neck connection, and any section interface of this three is all round rectangle, interface perimeter from small to large, again from big to small, girder
At swan-neck, swan-neck is extend into girder for junction with stringer, and it is not only and vertical that the stabiliser bar in girder is arranged in
Beam connection is also connected with girder, and mainly by main beam stress, 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 torsion break overall structure, while primary deformable is born by girder,
Stringer keeps stablizing, and avoids metal fatigue.
Compared with prior art, the beneficial effects of the present invention are: passing through the shape and stabiliser bar for redesigning stringer
Connection type guarantees the stabilization and entirety anti-twisting property of stringer and girder, guarantees that elastic deformation is concentrated mainly on girder, avoid
It is damaged caused by stringer stress is excessive, while guaranteeing the strength and stiffness of girder in the stabiliser bar of girder.
