Embodiment Construction

[0039] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0040] A four-way adjustable collapse energy-absorbing steering column (hereinafter referred to as the steering column), such as figure 1 , image 3 , Figure 5 , Figure 17 As shown, it includes an upper pipe string system 1 , a lower pipe string system 2 , a mounting bracket 3 and a locking mechanism 4 .

[0041] Upper string system 1, such as Figure 7As shown, it includes an upper column tube 11, an upper steering shaft 12, an upper bearing 13, a chute liner 14 (such as Figure 9 shown).

[0042] Such as Figure 8 As shown, the upper column tube 11 is a one-piece cast aluminum column tube, and the joints between the upper column tube 11 and the surrounding components are all machined, with high precision, light weight, and simple and elegant appearance. The lower end of the upper column tube 11 is provided with two parallel and symmet...

Abstract

The invention discloses a four-way adjustable crumpling energy absorption steering column. The four-way adjustable crumpling energy absorption steering column comprises an upper column system, a lower column system, an installation support and a locking mechanism. The upper column system comprises an upper column. A long-strip-shaped opening is formed in the pipe wall of the lower end of the upper column in the bus direction. A circular hole with the diameter larger than the width of the opening is formed in the root portion of the opening. The locking mechanism is connected to the two sides of the opening in a clamped mode. Through the design of sliding grooves and the opening in the upper column and through cooperation between the locking mechanism and the upper column system, the change of the aperture of the upper column can be controlled when the locking mechanism is drawn in and recovered. The upper column and a lower column are small in crumpling force and easy to control, the requirement for the crumpling energy absorption is better met, and driving comfort and passive safety of a whole vehicle are improved.

Description

technical field [0001] The invention relates to the field of automobile steering columns, in particular to a four-way adjustable collapse energy-absorbing steering column. Background technique [0002] The steering column is an important part of the steering system, and its basic function is to realize the transmission of steering torque. However, with the development of technology, consumers have put forward higher requirements for the driving comfort and safety of vehicles. The steering column is required to be able to adjust the vertical angle and the telescopic adjustment along the axis of the column on the whole vehicle to meet the ergonomic requirements of different drivers; at the same time, when the vehicle collides, the driver will collide with the steering wheel, In order to reduce the damage of the steering wheel to the human body during a collision, it is necessary for the column to have a collapse energy-absorbing function. [0003] Most of the existing steeri...
