Problems solved by technology

These structures have energy-absorbing functions, but the collapse force is affected by the size of multiple parts and cannot be effectively controlled. At the same time, after the intermediate shaft collides and collapses, the axial direction is easy to loosen or fall off, losing the steering function, and the collapse is realized by multiple parts. Energy absorption leads to complex structure and high cost

Abstract

The invention discloses a corrugated pipe crumple energy absorption steering intermediate shaft, which comprises a first joint fork, a cross bearing, a second joint fork and a corrugated pipe, whereinthe first joint fork is connected with the second joint fork through the cross bearing, and the corrugated pipe is arranged on the second joint fork in a sleeving mode. The intermediate shaft connecting shaft is designed into a hollow pipe, then the hollow pipe is designed into the corrugated shape, and when an automobile is collided, the corrugated pipe only depends on the physical property of the material of the corrugated pipe to deform and absorb energy.

Description

technical field [0001] The invention relates to the field of automobile steering systems, in particular to a bellows collapse energy-absorbing steering intermediate shaft. Background technique [0002] With the rapid development of social economy and the improvement of people's living standards, automobiles have become an essential means of transportation in our daily life. Daily travel, work, and travel are indispensable. While automobiles bring speed and convenience to our lives, they also provide Our life safety brings hidden dangers. Therefore, people have higher and higher requirements for automobile safety performance. The steering intermediate shaft is a very important part of the automobile steering system, and the quality of the steering intermediate shaft affects driving comfort and safety. [0003] There are many types of existing intermediate shaft energy-absorbing structures: 1) integrally welded intermediate shafts and telescopic intermediate shafts have no co...
