Problems solved by technology

[0007] The invention provides a side impact energy-absorbing automobile bridge assembly that can absorb side impact energy without vehicle frame collapse and deformation during side impact, and solves the problem of the need for vehicle body collapse and energy absorption in the existing automobile side impact. The problem of poor security
When a collision occurs, the part to be collided is the side protection bar (the side protection cylinder exceeds the body along the width direction of the car)

Embodiment 1

[0027] Embodiment one, see figure 1 , a side impact energy-absorbing automobile bridge assembly, including a vehicle frame 1, an axle housing 2, a front axle 3 and two side impact protection mechanisms 4.

[0028] Vehicle frame 1 is connected on axle housing 2 and front axle 3 by suspension mechanism.

[0029] 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 wheel joint 23 is connected with the rear wheel 11 .

[0030] The front axle 3 includes a cross bar 31 and two suspension arms 32 located at both ends of the cross bar. The suspension arm 32 is connected to the front wheel 12 .

[0031] Two side impact protection mechanisms 4 are distributed on the left and right sides of the vehicle frame 1 . The side impact protection mechanism 4 includes a side protectio...

Embodiment 2

[0048] Embodiment two, the difference with embodiment one is:

[0049] see Figure 5 , the inner peripheral surface of the inner circular tube 5161 is provided with a vane 5168 for guiding the rotation of the seal head 516 of the axle housing portion when the fluid flows through the inner circular 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.

[0050] During use, if the seal head 516 of the axle housing is sprayed out, before the an...

Abstract

The invention relates to an automobile bridge and particularly discloses a side impact energy absorption type automobile bridge assembly comprising an axle housing, a front axle, a frame and two sidecollision protection mechanisms arranged on the left side and the right side of the frame. The frame is connected to the axle housing and the front axle through a suspension mechanism; the axle housing is provided with a speed reducer mounting section and two half axle mounting sections arranged on two sides of the speed reducer mounting section; a wheel connector is arranged at the free end of each half axle mounting section; the wheel connectors are connected with wheels; the front axle comprises a cross rod and two cantilevers arranged at the two ends of the cross rod, and the cantilevers are connected with wheels; each side collision protection mechanism comprises a side protection rod extending in the front-back direction, one end of the side protection rod is provided with an axle housing part side collision energy absorption structure arranged on the half axle mounting section, and the other end of the side protection rod is provided with a front axle part side collision energyabsorption structure arranged on the cross rod. According to the side impact energy absorption type automobile bridge assembly, side impact energy can be absorbed without crumpling deformation of an automobile frame when side impact occurs, and a problem that the safety is poor due to the fact that an automobile body needs to crumple to absorb energy when an existing automobile is subjected to side impact is solved.

Description

[0001] This case is a divisional application with application number 2017103458674, filed on May 17, 2017, and named "side impact energy-absorbing vehicle bridge assembly". technical field [0002] The invention relates to an automobile bridge, in particular to a side impact energy-absorbing automobile bridge assembly. Background technique [0003] The bridge frame of the car is composed of the frame, the rear axle (drive axle) supporting the frame and the front axle of the car (also known as the front axle, which is the steering axle). Both ends of the drive axle and the front axle are connected to the wheels, and the frame passes through the suspension Attached to the frame. [0004] 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 ...
