Problems solved by technology

[0004] Based on the existing ordinary energy-absorbing column to absorb collision energy mainly rely on frictional force consumption, the energy consumed is limited, and most of the energy is still absorbed by the human body, which cannot form a good protection for the human body

Embodiment Construction

[0028] As shown in Figure 2, image 3 and Figure 4 As shown, this energy-absorbing steering column adds a group of energy-absorbing structures on the basis of the structure of the ordinary energy-absorbing column, that is, it consists of a coil spring 7, a lower spring seat 6, an upper spring seat 12, a rubber sleeve 4 and a lower shaft. Assembly 1 forms a set of energy-absorbing structures, that is, increasing the system elastic coefficient K and system damping C to adjust the magnitude of force and energy absorption.

[0029] The lower shaft assembly 1 of the energy-absorbing steering column is connected with the upper shaft assembly 9 through polyurethane pins 8 to form a shaft that can transmit torque; the upper and lower shafts pass through the upper end bearing 13 and the lower end rubber bearing 2 respectively with the upper and lower shells of the column Connected to realize rotation; the upper mounting seat casing 10 and the upper mounting seat 11 are welded and con...

Abstract

The invention relates to an automobile energy-absorbing steering column, consisting of a steering column installation base sleeve, a steering shaft and a steering column installation base; the upper installation base sleeve and the lower installation base sleeve are internally provided with an upper spring base, a lower spring base, a spring and a rubber sleeve; the upper spring base is arranged in the upper installation base sleeve, the axial positioning of the upper spring base is realized by a contracting structure which is arranged at the right end of the upper installation base sleeve; the lower spring base is arranged in the lower installation base sleeve and the axial positioning of the lower spring base is realized by a contracting structure which is arranged at the left end of the lower installation base sleeve; the spring is arranged between the upper spring base and the lower spring base; a steering lower shaft assembly is provided with a hole close to a rubber bearing; the external round of the steering lower shaft is sleeved with the rubber sleeve at the position of the hole. The automobile energy-absorbing steering column absorbs more elastic potential energy of the spring and the dissipation energy generated by damping pores by the added spring and damping pores compared with the normal energy-absorbing column on the energy-absorption, therefore, the bumping energy exerted on the human body is reduced, thus ensuring the spring not to rebound or to slowly rebound after being compressed and avoiding the damage of rebound force on the human body.

Description

technical field [0001] The invention relates to automobile steering technology, in particular to an automobile steering column structure. Background technique [0002] At present, the collision safety requirements of automobiles are getting higher and higher, and the requirements of various OEMs for passive safety technology in automobile design are also getting higher and higher. The country has also formulated clear regulations on related aspects, such as the national standard GB11557-89. , The maximum collision force is 11.123KN, and the maximum backward displacement of the steering wheel shall not exceed 127mm. Based on the need to protect the driver in a collision, the current steering column is designed to ensure that the rearward displacement of the steering wheel is not greater than 127mm during collision compression, and at the same time ensure that the collision force of the steering wheel on the driver's chest does not exceed 11.123KN, the structure of the curren...
