Embodiment Construction

[0022] refer to Figure 2-Figure 7 , The toothed energy-absorbing steering column includes a bracket 5, a shear block 6 and a column sleeve 7, and the material is plastic or synthetic material. The pipe column sleeve is installed in the middle part of the support, and the two sides of the support 5 have a figure-eight groove 51, and the groove edge of the figure-eight groove has internal teeth 52. The middle part of the shear block 6 has a figure-eight boss 61, and the figure-eight projection is clamped between the front and rear plates of the shear block 6. There are external teeth 62 on the edge of the eight-shaped boss 61, and a bolt hole 63 is provided in the middle of the shear block 6. During installation, the inner teeth 52 mesh with the outer teeth 62, so that the shear block 6 is connected with the bracket 5, and then the shear block 6 is connected with the instrument panel beam through a bolt group.

Abstract

A tooth-shaped energy-absorption steering column comprises a support, two shear blocks and a column sleeve. The column sleeve is arranged in the middle of the support, inverted-V-shaped grooves are opened in the two sides of the support, inverted-V-shaped bosses are arranged in the middles of the shear blocks, the two shear blocks are mounted on the two sides of the support through the inverted-V-shaped bosses respectively, and bolt holes are formed in the middles of the shear blocks which are connected with an instrument panel beam through bolt sets. The steering column is characterized in that inner teeth are arranged at the edges of the inverted-V-shaped grooves of the two sides of the support, outer teeth are arranged at the edges of the inverted-V-shaped bosses of the shear blocks correspondingly, and the inner teeth and the outer teeth are meshed to connect the shear blocks and the support together. By means of the steering column, the crumple force controllability can be improved, so that the driver safety during collision of vehicles is improved; besides, the steering column is simple in structure and convenient to mount.

Description

technical field [0001] The present invention relates to a vehicle steering system, and more particularly to an energy-absorbing steering column. Background technique [0002] With the development of the vehicle industry, people's awareness of vehicle safety is getting higher and higher, especially after a vehicle collides, whether it can effectively protect the driver has become a standard for people to evaluate the quality of a car. [0003] Such as figure 1 As shown: the current steering column with the energy absorbing device includes a bracket 1 , a shear block 2 , a cylindrical injection molding block 3 and a column sleeve 4 . Both sides of the bracket are provided with eight-shaped grooves 11, and both sides of the eight-shaped groove 11 are provided with injection molding holes 12. Bolt mounting holes 21 are arranged in the middle of the shear block 2, and four injection holes 22 are arranged in both sides, and a figure-eight boss 23 is sandwiched in the middle. Du...
