Embodiment 1

[0019] Embodiment one, see figure 1 , an automobile front axle provided with a side impact energy-absorbing structure, comprising a front axle 3 .

[0020] The front axle 3 includes a cross bar 31 and two suspension arms 32 located at both ends of the cross bar. A side impact energy-absorbing structure 41 is respectively provided at the left and right ends of the cross bar 31 .

[0021] The side impact energy-absorbing structure 41 includes a drive frame 411 , a cylinder 412 , a compression piston 413 , a first frictional energy-dissipating cylinder 414 and a second frictional energy-dissipating cylinder 415 .

[0022] A pipe body 33 is slidingly sealed in the cross bar 31 . The pipe body 33 extends in the left-right direction. The inner space of the pipe body 33 constitutes a total of two second frictional energy dissipation cylinders 415 of the two side impact energy absorbing structures 41 . A third friction layer is provided on the inner peripheral surface of the secon...

Embodiment 2

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

[0030] see image 3 , the inner peripheral surface of the inner tube 4161 is provided with fan blades 4168 that guide the sealing head 416 to rotate when the fluid flows through the inner tube. The sliding bar 31 is also provided with a support frame 518 . The supporting frame 418 is rotatably connected with a connecting sleeve 419 through a plane bearing 4181 . The connecting sleeve 419 is connected with an annular blade 4191 . A limiting portion 4192 is formed between the annular blade 4191 and the connecting sleeve 419 . The blade 4191 is provided with an annular cutting edge 4193 . The annular cutting edge 4193 is aligned with the bottom wall 4163 . The outer diameter of the blade 4191 is equal to the inner diameter of the inner circular tube 4161.

[0031] During use, if the sealing head 416 is ejected, before the annular cutting edge 4193 contacts the bottom wall 4163, the connecting sleeve 419 is firs...

Abstract

The invention relates to automobile front axles. An automobile front axle provided with side impact energy-absorption structures comprises a front axle body; the front axle body comprises a transverse rod and two cantilevers located at the two ends of the transverse rod; the side impact energy-absorption structures are arranged at the left and right ends of a sliding rod correspondingly; each side impact energy-absorption structure comprises an air cylinder arranged in the transverse rod and extending in the horizontal direction, a compression piston slidably connected in one end of the air cylinder in a sealed mode, and a driving frame for driving the compression piston; a long-strip-shaped receding hole extending in the horizontal direction is formed in the transverse rod; the driving frame is arranged in the long-strip-shaped receding hole in a penetrating mode; a jet hole is formed in the other end of the air cylinder; and a seal head is connected in the jet hole, wherein the seal head is pressed out by air in the air cylinder when the air pressure in the air cylinder rises to the set value. According to the automobile front axle provided with the side impact energy-absorption structures, side impact energy can be absorbed without crumpling deformation of an automobile frame during side impact, and the problem that an automobile body needs to be crumpled to absorb the energy during side impact of an existing automobile, and consequently safety is poor is solved.

Description

technical field [0001] The invention relates to an automobile front axle, in particular to an automobile front axle provided with a side impact energy-absorbing structure. Background technique [0002] The front axle of the car is used to install the front wheels, support the weight of the front of the car, and connect with the frame with the front suspension. In Chinese patent application number 2011201792654, the authorized announcement date is December 28, 2011, and promptly discloses a kind of automobile front axle of existing structure in the patent document of name " automobile front axle assembly ". The front axle of the automobile includes a cross bar and two cantilever arms. A vehicle frame supporting part is respectively arranged at both ends of the cross bar. A cantilever is respectively connected to both ends of the cross bar. The cantilever is provided with a king pin hole. During use, the steering knuckle is connected with the front axle through the kingpin pa...
