Embodiment Construction

[0031] Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail:

[0032] figure 1 and Figure 4 The shown vehicle collision energy absorbing device includes a steering gear mounting bolt 1 connecting the steering gear mounting seat 2 and the sub-frame 3, and a locking nut 4 for locking the steering gear mounting bolt 1. The steering gear 5 in this embodiment is fixed on the steering gear 5. There are two steering gear mounting bases 2 , and the steering gear 5 is connected and fixed on the subframe 3 through the steering gear mounting base 2 , the steering gear mounting bolts 1 and the locking nuts 4 . like figure 2 and image 3 As shown, the rod body of the steering gear mounting bolt 1 is provided with a groove 1-2, and the groove 1-2 is provided with two discontinuous front and rear incisions along the outer circumference of the rod body. In the forward direction, the direction of the rear incision deviates from t...

Abstract

The invention discloses a vehicle collision energy absorption device, which relates to the technical field of collision energy absorption. Above, the rod body of the steering gear mounting bolt is provided with a groove, and the groove faces the joint interface connecting the steering gear mounting seat and the sub-frame. The present invention solves the problem that the powertrain collapses and absorbs limited energy when the existing vehicle collides.

Description

technical field [0001] The invention relates to the technical field of collision energy absorption, in particular to a vehicle collision energy absorption device. Background technique [0002] At present, the layout of the vehicle cabin is becoming more and more compact. Due to space constraints, the gap between the engine, the gearbox and the steering gear is small. When the vehicle collides, the powertrain is easily blocked by the steering gear during the rearward movement and sinking process, which greatly weakens the vehicle. Crash energy absorption performance. An existing steering gear is fixed by means of bolt connection. The bolts installed are all ordinary bolts. The main force direction of normal work is Y direction and the non-main force direction of normal work is X direction, but the main force direction is X during collision. to have the same strength. During the collision of a vehicle with this structure, the steering gear seriously affects the rearward move...
