Abstract

The utility model discloses a front shaft blank body for a vehicle, which comprises a shaft end and a shaft beam. Seamless steel tubes are bent to form the shaft beam. A part of tube sections of the shaft beam are rectangle shaft tubes. The seamless steel tubes are rolled to form the rectangle shaft tubes. The front shaft blank body for the vehicle of the utility model has low cost, short production period and small vehicle front shaft blank, and avoids the shaft welding processing technology as much as possible or completely to make the rigidity of the shaft body and other mechanism performances sufficiently satisfy the design requirements.

Description

A kind of automobile front-axle base substrate

Technical field

The utility model relates to technical field of automobile parts, more particularly, relates to a kind of automobile front-axle base substrate that bears the autotruck of tare.

Background technology

Vehicle for most of rear drive, automobile front-axle does not generally have the function of driving, it as the wheel that connects both sides, bear the auto parts and components of tare, the common I-shaped solid beam of its front axle base substrate main beam structure, base substrate as the disclosed bloster of CN 101014469A, the tooling cost of the I-shaped solid beam front axle of this forging is bigger, and number of molds and expense are all very high, and commonality is not strong; Usually the propons that turns to that forges processing is prepared production from frock, and the duration is all very long, and correspondingly time of delivery is also very long; On the other hand, this propons in use deformation occurs because rigidity is not enough easily, causes unnecessary wear on tyres.On the external at home automotive market, also having some automakers that the bloster of automobile front-axle is made is the bigger hollow shaft tubular construction of rigidity, normally with a steel plate on the U type slot welding, at one section steel billet of bloster two ends welding, make the front axle base substrate form the structure of a peviform then, the centre is the end of peviform, two ends connect parts such as wheel hub, and hanger bracket is located on the bottom of peviform, and its shortcoming is large-area welding processing, form long weld seam, weakened the mechanical characteristics and the safety of front axle.

Summary of the invention

The utility model purpose provides a kind of with low cost, automobile front-axle base substrate that the production cycle is short and small, as far as possible or avoid the axis body technique for welding fully, the rigidity of axis body and other mechanism performance is fully met design requirement, to overcome the deficiencies in the prior art.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of automobile front-axle base substrate, comprise axle head, bloster, and it is characterized in that: described bloster is bent by solid drawn pipe and forms.

The part pipeline section of described bloster is the rectangle central siphon that is formed by the solid drawn pipe roll extrusion.

Described axle head and bloster are integral structures, the embedded inserted block of axle head, and described axle head is provided with the through hole that runs through axle head and inserted block.

Described inserted block and axle head welding are fixing.

Described axle head and bloster are welded to connect, and described axle head comprises pin-and-hole sleeve and scarfweld portion.

But the scarfweld portion intercalation of described axle head is in the central siphon at bloster two ends.

The utlity model has following beneficial effect:

The front axle base substrate curves type by solid drawn pipe roll extrusion, forging, and the solid H-girder of its ratio of rigidity is strong, and has saved welding process, has improved the mechanical characteristics of bearing, has increased service life.

It is little that the front axle base substrate is processed required moulds of industrial equipment quantity, and obviously reduction of erection time and time of delivery, frock expense, tooling cost obviously reduce.

The specific embodiment

The specific embodiment one,

As shown in Figure 1 to Figure 3, as an embodiment of the present utility model, the utility model provides a kind of automobile front-axle base substrate, comprises axle head 1, bloster 2.Bloster 2 is processed by solid drawn pipe, adopt the pipe roll extrusion to be square tube, to be bent into the process of peviform then, the part pipeline section 2-1 of bloster 2 is rectangle central siphons, specifically: the peviform bottom of bloster 2 is square-sections, the pipeline section that two bottom sides connects axle head 1 is circular pipeline section or sub-circular pipeline section, 2 one integral body of axle head 1 and bloster constitute, and are compressed to rectangular tube.Its outer rim is semicircle, also establishes pivoting hole at axle head 1, and the base substrate of axle pivots so that front-axle steering saves relatively.At axle head 1 embedded one inserted block with holes of rectangle pipeline section, the axial line of its through hole 4 overlaps with the pivoting hole of axle head 1.Inserted block and axle head 1 welding are fixing or otherwise fixing.The forming step of front axle base substrate specifically can be:

One, earlier circular shaft pipe two ends caliber is dwindled;

Two, the centre portion roll extrusion side of pushing away with the circular shaft pipe makes the central siphon cross section be converted to the rectangle central siphon from circle;

Three, the two ends of circular shaft are processed as the axle head 1 of square-section;

Four, the front axle base substrate is forged and is curved peviform;

Five, the processing of axle head 1 shape.

After the machine-shaping, fill in a metallo-inserted block 3 from both sides axle head 1, the outer end of this inserted block 3 is the semicircle cambered surface, and the semicircle outer margin contour of the upper and lower wall of its shape and axle head 1 matches, and inserted block 3 is weldingly fixed on the axle head 1 along axle head 1 border line.After inserted block 3 welding, perpendicular to axle head 11 upper and lower wall bore hole processing through holes 4.

The front axle base substrate of present embodiment is the single type structure, and the centre need not be welded to connect, and the weld of axle head 1 and inserted block has strengthened the safety of front axle in the low stress area of base substrate; Bloster 2 central parts are the square-section, make front axle that more favorable rigidity design be arranged, and have tangible progress than prior art.

The specific embodiment two,

As a kind of improvement of the present utility model, axle head 1 and bloster 2 are connected with welding manner, as Fig. 4 to shown in Figure 5, axle head 1 constitutes by two, pin-and-hole sleeve 5 and scarfweld portion 6, pin-and-hole sleeve 5 and scarfweld portion 6 are orthogonal, and also welding is fixing in the central siphon with scarfweld portion 6 insertion blosters, 2 two ends.Present embodiment is that smallclothes are processed in addition with axle head, 1 , has improved production efficiency, makes processing more easy to be reliable.The processing of bloster 2 makes this part central siphon cross section be converted to the rectangle central siphon from circle the centre portion roll extrusion side of pushing away of circular shaft pipe; Forge again and curve peviform.
