Description
Technical field
The present invention relates to Rail car manufacture field, more specifically, relate to the manufacture method of a kind of axle housing, vehicle bridge, vehicle and axle housing.
Background technology
In prior art, the heavy type carrying that the heavy-dutys vehicle such as large-tonnage industrial wheeled equipment use drives the axle housing of vehicle bridge to be the basic components installing main reduction gear, diff, semiaxis, wheel hub and suspension.The Main Function one of axle housing is carrying, bear in vehicle driving-cycle start, braking, turn, uneven road surface time complete vehicle weight, bear complete vehicle quality when the conversion of various operating mode or various working occur simultaneously and shift the load variations or impact that cause; Two is support and protect main reduction gear, diff and semiaxis, drg etc., is driving system, the end bearing of brake system, guard block.According to the axle housing of axle housing from central siphon in function, structural different requirement, the general different materials that adopts press distinct methods making axle housing.Structure and the manufacturing process of pressing axle housing employing are at present different, and integral axle housing mainly divides casting bridge shell and bulging axle housing.
Fig. 1 to Fig. 4 shows the structure of casting bridge shell in prior art.Wherein Fig. 1 is the stereo decomposing structural representation of casting bridge shell in prior art; Fig. 2 is the main TV structure schematic diagram with semi-sictional view of the casting bridge shell shown in Fig. 1; Fig. 3 is that the A-A of Fig. 2 is to structure for amplifying schematic diagram; Fig. 4 is that the B-B of Fig. 2 is to structure for amplifying schematic diagram.
As shown in Figures 1 to 4, the axle housing 110 of casting bridge shell 100 is casting bridge shell body, and this axle housing 110 is cast as one with flange 120.Zhong Mei one end, two ends of axle housing 110 is provided with axle housing square section portion 111 and axle housing circular section portion 112.Axle housing square section portion 111 is also provided with for the plug welding point 113 with central siphon 130 plug welding.When connecting central siphon 130 with axle housing 110, central siphon 130 and axle housing 110 adopt force fit and the mode of plug welding.
Because casting bridge shell quality is large, central siphon is long, high material consumption, profile is clumsy.Replaced by lightweight, that reliability is high bulging axle housing gradually at present.
Fig. 5 to Fig. 9 shows the structure of bulging axle housing in prior art.Wherein, Fig. 5 is the perspective view of bulging axle housing in prior art; Fig. 6 is the stereo decomposing structural representation of the bulging axle housing shown in Fig. 5; Fig. 7 is the main TV structure schematic diagram of the bulging axle housing shown in Fig. 5; Fig. 8 is that the C-C of Fig. 7 is to structure for amplifying schematic diagram; Fig. 9 is that the D-D of Fig. 7 is to structure for amplifying schematic diagram.
As shown in Figures 5 to 9, the axle housing 210 of bulging axle housing 200 adopts bulging axle housing, and this axle housing 210 adopts the operations such as steel pipe heating, bulging, undergauge to process.Wherein axle housing 210 two ends are formed to axle housing circular section portion 212 by portion 211, axle housing square section transition shaping.Bulging axle housing can be transitioned into circular section by steel tube forming technique from square section, to be connected with central siphon 230.Central siphon 230 adopts Forging Parts, and flange 220 adopts steel plate to cut.When connecting, central siphon 230 and axle housing 210 adopt circle to weld circle electron ray annular arrangement weld seam, and flange 220 and axle housing 210 adopt fillet weld seam.In Fig. 5, W1 represents the fillet weld between flange 220 and axle housing 210, and W2 represents the electron ray annular arrangement weld seam between central siphon 230 and axle housing 210.
Realizing in process of the present invention, although contriver finds that good relative to its shock resistance of casting bridge shell 100, the fully loaded reliability of bulging axle housing 200 is high, quality light, at least there is following problem in above bulging axle housing of the prior art:
As shown in Figures 5 to 9, the axle housing square section portion 211 of bulging axle housing 200 is the spring block places directly carrying complete vehicle weight, this place's Cross section Design is fabricated to square-section, because square-section is larger relative to round section bending resistant section coefficient, bending resistance and strength at repeated alternation are all higher than round section.The width L1 of this square-section is limited to the installation of main reduction gear, and stock size change is little.For ease of being connected with the round section of central siphon 230, the square-section at axle housing 210 two ends needs progressive forming to be transitioned into round section, and due to the restriction of the job operation that is subject to bulging axle housing, the height H 1 in its axle housing square section portion 211 must not be greater than 1.2 with ratio (the calling height to width ratio in the following text) requirement of the width L1 in axle housing square section portion 211.But in fact, in prior art, this height to width ratio generally only reaches 1.08.But in heavy vehicles, in wheelspan wheel crane as wide in large-tonnage, axle housing square section portion is as adopted the cross sectional shape of above height to width ratio less than 1.2, then rigidity and strength at repeated alternation deficiency, can not meet load bearing requirements.If the height H 1 in axle housing square section portion is increased, then the bending resistant section coefficient of axle housing be can improve, carrying rigidity and strength at repeated alternation improved.Such as, through adjusting, the height needed for driving axle shell of the wide wheelspan wheel crane of large-tonnage need make the height to width ratio in axle housing square section portion be greater than 1.5.But according to the forming technology of existing bulging axle housing, be greater than at height to width ratio that 1.5 bases are transitioned into axle housing circular section portion 212 axle housing square section portion 211 is infeasible.As the width L1 in axle housing square section portion 211 is increased, reduce height to width ratio, then can cause the problem that main reduction gear can not be installed.
