Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail, it should be appreciated that these embodiments are merely to illustrate this Utility model rather than limit scope of the present utility model, after having read this utility model, those skilled in the art couple The amendment of the various equivalent form of value of the present utility model all falls within the application claims limited range.

According to axle housing a kind of shown in Fig. 1 to Fig. 6, including axle housing 60, the two ends of axle housing 60 are respectively connected with central siphon 10, the end face at the middle part of axle housing 60 connects has axle housing lid 20, each central siphon 10 all to include extrusion axis head 11, push away square shaft Pipe portion 12, pushes away square shaft pipe portion 12 and connects extrusion axis head 11 and axle housing 60, additionally, axle housing 60 has cavity, Gu Qiao Shell body 60 can carry out arranged below further: according to Fig. 2 and Fig. 5, the inwall of axle housing 60 is fixed with some reinforcements Plate 30, additionally, extrusion axis head 11, to push away square shaft pipe portion 12, axle housing 60, axle housing lid 20 and reinforcing plate 30 be by pipe blank Global formation;Axle housing 60 is by obtained by water high pressure forming by internal expansion.

Understanding accordingly, this axle housing is monolithic construction, the extruding of pipe blank, water high pressure expansion molding prepare, material profit Significantly improve than punch welding technique by rate, and welding tooling mould can be cancelled.Product matter is had more compared with cast type axle housing The advantage that amount is light, rigidity is sufficient, intensity is good, reduces machining amount, saves raw material;Additionally, reinforcing plate 30 has been possible not only to The intensity increasing this axle housing of effect, it also has the effect of gear oil.

Additionally, according to shown in Fig. 1, Fig. 2 and Fig. 6, extrusion axis head 11 is fixed with circular arc with pushing away junction, square shaft pipe portion 12 Transition face 50.

According to shown in Fig. 2 to Fig. 4, the cross section of extrusion axis head 11 is circular, and the cross section pushing away square shaft pipe portion 12 is square Or rectangle or circle.

And, according to Fig. 6, in the present embodiment, each square shaft pipe portion 12 that pushes away all is fixed with damping by fixed mount Device 40, and the relative axle housing lid 20 of amortisseur 40 is symmetrical.By amortisseur 40, can effectively improve the antidetonation effect of this axle housing Really, additionally, the relative axle housing lid 20 of amortisseur 40 is symmetrical, damping effect can be further increased, it is to avoid lead because of vibration Cause this axle housing impaired, thus extend the physical life of this axle housing.

Additionally, offer several oil-ins 21 at axle housing lid 20;I.e. can offer an oil-feed on this axle housing lid 20 Mouth 21, it is possible to offer the oil-in 21 of two or more (including two), according to Fig. 1, Fig. 2 and Fig. 6, at the present embodiment In, this axle housing lid 20 offers two oil-ins 21, on the one hand can improve user injects the speed of lubricating oil, the opposing party Face, if only one of which oil-in 21, and this oil-in 21 blocks, then user cannot inject lubricating oil, and this setting just can be effective The generation avoiding this situation.

Below being only preferred implementation of the present utility model, protection domain of the present utility model is not limited merely to above-mentioned Embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It is right to it should be pointed out that, For those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, These improvements and modifications also should be regarded as protection domain of the present utility model.
