The invention is a steering system to improve the vehicle front collision performance (1) rotating during impact and interacting via stepped energy absorbers (3.5) a movable front element (2) 5 which is structured to absorb impact energy. It includes. The subject of the invention, the steering mechanism (1), is an effective energy absorption mechanism in case of collision. It provides. The impact force on the impact surface (2.1) is transmitted to the bushing of the movable front element (2). (4) causes it to rotate around. During this rotational movement, the movable front element (2) gradually increases the energy on the fixed rear element (3) 10 It interacts with absorbers (3.5). The graded energy absorbers (3.5) have different its structure at different heights allows the collision energy to be distributed gradually and in a controlled manner. It ensures that the impact force is absorbed. In this way, the impact force is distributed in a directed manner, and The sudden loads transmitted to the vehicle structure are reduced. The rotational movement of the movable front element (2) and interaction with cascaded energy absorbers (3.5) a wider range of collision energy 15 by allowing it to spread across the area and be absorbed over a longer period, the front of the vehicle It improves collision performance. In one application of the invention, the guide (1) is placed on a movable stop surface (2.4) having a movable front element (2) and a fixed rear element with a fixed stopping surface (3.1) It contains element (3). 20 This configuration optimizes energy absorption during a collision while minimizing overheating. It prevents rotation, thus preserving the integrity of the steering system and ensuring in-vehicle safety. increases.
