Embodiment 1

[0019] Embodiment one, see figure 1 , an automobile axle housing provided with a side impact energy-absorbing structure, comprising an axle housing 2.

[0020] The axle housing 2 is provided with a reducer installation section 21 and two axle shaft installation sections 22 located on both sides of the reducer installation section. The free end of the axle shaft mounting section 22 is provided with a wheel joint 23 . The reducer installation section 21 is provided with a reducer installation cavity 24 . The half-shaft installation section 22 is provided with a half-shaft installation channel 25 extending from the end surface of the wheel joint 23 along the extension direction of the half-shaft installation section and communicating with the reducer installation cavity. A side impact energy-absorbing structure 51 is arranged inside the half-shaft installation section 22 .

[0021] The side impact energy-absorbing structure 51 includes a drive frame 511 , a cylinder 512 , a co...

Embodiment 2

[0029] Embodiment two, the difference with embodiment one is:

[0030] see image 3 , the inner peripheral surface of the inner tube 5161 is provided with a vane 5168 that guides the sealing head 516 to rotate when the fluid flows through the inner tube. The half shaft installation section 22 is also provided with a support frame 518 . The supporting frame 518 is rotatably connected with a connecting sleeve 519 through a plane bearing 5181 . The connecting sleeve 519 is connected with an annular blade 5191 . A limiting portion 5192 is formed between the annular blade 5191 and the connecting sleeve 519 . The blade 5191 is provided with an annular cutting edge 5193 . The annular cutting edge 5193 is aligned with the bottom wall 5163 . The outer diameter of the blade 5191 is equal to the inner diameter of the inner circular tube 5161.

[0031] During use, if the sealing head 516 is ejected, before the annular cutting edge 5193 contacts the bottom wall 5163, the connecting s...

Abstract

The invention relates to an axle housing of a drive axle, and discloses an automobile axle housing with side impact energy absorption structures. The automobile axle housing comprises an axle housing,wherein half-axle mounting sections are arranged at the two ends of the axle housing; the half shaft mounting sections are provided with side impact energy absorption structures; each side impact energy absorption structure comprises an annular air cylinder, a compression piston and a driving frame, wherein the annular air cylinder is arranged in the half shaft installation section, surrounds thehalf shaft installation channel and extends in the left-right direction, the compression piston is connected into one end of the air cylinder in a sealed and sliding mode, and the driving frame drives the compression piston. The half shaft installation sections are provided with long-strip-shaped receding holes extending in the left-right direction, the driving frames are arranged in the long-strip-shaped receding holes in a penetrating mode, a spraying hole is formed in the other end of each air cylinder, and a sealing head which is pressed out by air in the air cylinder when the air pressure in the air cylinder rises to a set value is connected in each spraying hole. The automobile axle housing has the advantage that side impact energy can be absorbed during side impact, and the problemof poor safety caused by the fact that an automobile body needs to collapse to absorb energy during side impact of an existing automobile is solved.

Description

[0001] This case is a divisional application with application number 2017103458602, filed on May 17, 2017, and titled "Automobile Axle Housing with Side Impact Energy Absorbing Structure". technical field [0002] The invention relates to an axle housing of a drive axle, in particular to an automobile axle housing provided with a side impact energy-absorbing structure. Background technique [0003] The composition of drive axle is composed of final reducer, differential, half shaft and axle housing. The final drive, differential, and drive axle components are installed in the drive axle housing, located at the rear of the car, and the power is transmitted to the rear wheels. Promptly disclose a kind of existing axle housing in the patent document of CN205853768U in Chinese patent publication. The basic structure of the existing axle housing includes the axle housing body. The axle housing body is provided with a reducer installation section and two half-shaft installation s...
