Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0032] figure 1 and Figure 4 The vehicle collision energy-absorbing device shown includes the steering gear mounting bolt 1 connecting the steering gear mounting base 2 and the subframe 3 and the lock nut 4 for locking the steering gear mounting bolt 1. The steering gear 5 of this embodiment is installed and fixed. There are two steering gear mounts 2, and the steering gear 5 is connected and fixed on the subframe 3 through the steering gear mounts 2, the steering gear mounting bolts 1 and the lock nuts 4. Such as 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 slits along the outer circumference of the rod, and the front slit faces the side of the vehicle. In the forward direction, the direction of the rear notch i...

Abstract

The invention discloses a vehicle collision energy absorption device, and relates to the technical field of collision energy absorption. The device comprises a steering gear mounting bolt and a locking nut which are connected with a steering gear mounting base and an auxiliary frame, and the steering gear mounting base is fixed to a steering gear; a groove is formed in a bolt body of the steeringgear mounting bolt, and the groove faces the joint interface for connecting the steering gear mounting base with the auxiliary frame. According to the device, the problem that when existing vehicles collide, collapse and energy absorption of a power assembly are limited is solved.

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, gearbox and the steering gear is small. When the vehicle collides, the powertrain is easily blocked by the steering gear during the process of moving backward and sinking, which greatly weakens the vehicle. Collision energy absorption performance. An existing steering gear is fixed by bolt connection. The bolts installed are all ordinary bolts. The main direction of force in normal operation is Y direction and the non-main direction of force in normal operation is X direction, but the main direction of force in collision is X direction. have the same intensity. When a vehicle with this structure collides, the steering gear seriously affects the rearward...
