Embodiment Construction
[0011] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. For ease of description, only the parts related to the embodiments of the present invention are shown. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.
[0012] Such as figure 1 , figure 2 As shown, the present invention provides a vehicle cushioning and energy-absorbing direction column, which includes an upper column 1 and a lower column 2, one end of the lower column 2 is inserted into the upper column 1 and is set together, and the upper column 1 and the lower column There are steel balls 3 in the interference fit between the cylinders 2, and the steel balls 3 are limited on the sliding sleeve 4 which acts as a cage, and the ...

The invention provides a vehicle buffer energy absorption direction column which comprises an upper cylinder barrel and a lower cylinder barrel. One end of the lower cylinder barrel extends into the upper cylinder barrel to be installed in a sleeved mode, a steel ball is arranged between the upper cylinder barrel and the lower cylinder barrel in an interference fit mode, is limited in a slide sleeve having the retainer effect and is in interference fit with the upper cylinder barrel and the lower cylinder barrel, the lower end portions of the cylinder barrel form limiting portions with the inner and outer diameters larger than those of the remaining portions through chambering, and the inner and outer diameters of the lower self section of the upper cylinder barrel are correspondingly larger than those of the upper half section. Compared with an existing common vehicle buffer energy absorption direction column structure, the vehicle buffer energy absorption direction column is simple inn structure, constant in washboarding force value, low in manufacturing cost and safe and reliable in use.
Description
technical field [0001] The present invention relates to vehicle components, particularly collapsible vehicle steering cylinders. Background technique [0002] When a vehicle collides violently, the driver tends to lean forward due to inertia, and the chest of the human body will collide with the steering wheel. In order to reduce the impact on the driver's chest, some vehicles design the steering column as The collapsible structure of two to three sections, when subjected to a strong impact, the steering cylinder collapses and folds, which can disperse some of the impact force transmitted from the steering cylinder to the human body due to the impact. [0003] Existing automobile steering cylinders are generally designed with complex structures and high manufacturing costs. When a collision accident actually occurs, the collapse force value is not constant enough, and the effect of the cushioning system is not good. Contents of the invention [0004] The object of the pre...
