Description
Technical field
The utility model relates to a kind of high rigidity semitrailer axle axis body, belongs to Automobile shaft field.
Background technology
The axis body cross-sectional plane of the semitrailer axle that at present, semitrailer axle originating firm in home and abroad is produced is all square or circular.Axis body cross-sectional plane in patent CN2374376Y " Integral axle of semitrailer ", patent CN201925322U " a kind of Novel axle ", patent CN201506215U " Integral axle that a kind of semitrailer is used " and patent CN201228039Y " a kind of axis body of Trailer car shaft " is all square.Use patent CN202015776U " a kind of axle push shaping apparatus " and the described method moulding of patent CN2455399Y " a kind of apparatus for shaping square rear axle of semi-trailer ".And with some little tonnage semitrailer axle and farm trailer axletrees of 146 mm dia steel pipes and 127 mm dia steel pipe's production, as mostly the axis body cross-sectional plane of patent CN101547914A " connecting structure of semitrailer axle and suspension " is circular.For these axletrees, because axis body shape is fixing, if need to improve its rigid nature, the methods that improve axis body wall thickness that adopt more.So not only improve the cost of axletree, also can bring the increase of axletree weight.
Along with home and abroad is to the particularly day by day raising of commercial transport vehicle lightweight requirements of automobile, various types of auto-parts are all using maintaining the constant and Lightweight Technology that reduces to greatest extent own wt of performance as weighing one of index of its product advance.The various products that possessed lightweight meaning continue to bring out and put goods on the market.
At the axletree in trailer, superimposed trailer field particularly in the production of integral type semitrailer axle, because integral axle head heat is revolved the progress of the technology of rolling and steel pipe partial and thicken in advance the use of technique, use the spindle nose performance of the lightweight axletree of producing compared with thin-wall steel tube to be equivalent to; The spindle nose performance that has even exceeded the standard axletree that uses the production of standard thickness steel tube place having.But on middle axis body, the bending resistant section modulus bringing due to wall thickness reduction reduces the reduction of the axis body rigidity causing, and but becomes a difficult problem that hinders the development of lightweight axletree.To use 14 millimeters of wall thickness, 178 mm dia solid drawn pipes, revolve roll process moulding spindle nose by ordinary hot, the 13 tons of Integral axle of semitrailers (hereinafter to be referred as standard axletree) that utilize cold extruding formation process processing axis body are example, its axis body cross-sectional plane as Fig. 1 be 150 × 150 millimeters square, connect with arc transition, its bending resistant section modulus is 288203.48.And 12 millimeters of wall thickness 178 mm dia solid drawn pipes of use, revolve roll process or first steel pipe partial by advanced heat and thicken and re-use ordinary hot and revolve 13 tons of superimposed trailer integral light-weights of roll process moulding and quantize axletrees (hereinafter to be referred as lightweight axletree), the section shape of its spindle nose and spindle nose performance and standard axletree are approximate or suitable.And the axis body of the same profile of cold extruding formation process processing, due to 2 millimeters of the minimizings of wall thickness, its bending resistant section modulus is 256347.47.Reduce by 11% than standard axletree.
Utility model content
Improve the demand of rigidity, the problem of solution lightweight axletree axis body rigidity deficiency in order to meet standard axletree, the utility model provides a kind of high rigidity semitrailer axle axis body.
The utility model solves the technical scheme that its technical matters adopts and is to provide a kind of high rigidity semitrailer axle axis body, axis body comprises spring block fitting plane, the vertical surface adjacent with spring block fitting plane and the relative lower plane with spring block fitting plane, it is characterized in that, vertical surface and lower plane are combined into abnormally-structured.
The lower part of described vertical surface and lower plane form U-shaped structure.
U-shaped structure comprises the first bottom circular arc and is connected circular arc, and the first bottom circular arc connects vertical surface by connecting circular arc.
The latter half of described vertical surface and lower plane form different U-shaped structure.
Described different U-shaped structure comprises the second bottom circular arc and is connected tangent line, and the second bottom circular arc connects vertical surface by connecting tangent line.
Described connection tangent line is horn-like.
Different U-shaped structure can transition form V character form structure.
Retain the shape invariance of spring block fitting plane of axis body, and only change vertical surface the latter half spring block and make constant apart from the distance of axle centerline.The length of the vertical surface shortening, the limit of shortening is the requirement that meets standard axletree spring block and the welding of the utility model axletree axis body.So both ensure the commonality of spring block, also ensured that axle center was the same with standard axletree with the distance between spring block, thereby do not affected the height of axletree and suspension or car load assembling aftercarriage.No matter the suspension or the moral formula that are American formal dress, anti-dress hang, leaf spring type Pneumatic Suspension can not cause the variation of hanging with vehicle frame assembling trunk height.Attaching parts between axle body and leaf spring does not need any change yet.
Because whole axletree is also to be produced and processed with solid drawn pipe by standard axletree, ensure the constant fundamental principle of cross-sectional plane outside face girth, lower plane and vertical surface are made into U-shaped or different U-shaped, and with tangent line or connect circular arc and connect bottom circular arc and vertical surface.Size, the off centering of bottom circular arc number determine according to the form hanging, requirement or the comformability that hangs accessory.By this distortion, increase the bending resistant section modulus of axis body cross-sectional plane, thereby improve the rigidity of axletree.Concrete axis body cross-sectional plane can according to client to the rigidity of axletree requires, the situation of suspension form and accessory, manufacturer may change cold extruding equipment and roll system license degree and difference.
The beneficial effect that the utility model has is: by the change of axis body shape of cross section, improve the bending resistant section modulus of axis body, thereby improve the rigidity of axis body.And this distortion can not cause the variation of car load height.Suspension and vehicle bridge are assembled required connecting accessory great majority can utilize existing accessory.Be easy to processing.
