Abstract

The invention discloses a clamp for the crushing performance test of an automobile steering column and a device thereof and a method using the device. The clamp comprises a first fixing support and asecond fixing support which are arranged in a mirror surface mode. The first fixing support and the second fixing support are both in an L shape. An upper end fixing hole and a lower end fixing hole are formed in the upper portion and the lower portion of the inner side of each of the fixing brackets respectively; and an upper end fixing plate and a lower end fixing plate are installed at the upper end fixing hole and the lower end fixing hole respectively. The test device comprises a stretcher base; a working table and a clamp are sequentially installed on the stretcher base; and a to-be-tested automobile steering column is fixed by the clamp. In testing, a pressure is applied to a to-be-tested automobile steering column by a pressing head. Therefore, the crushing performance test requirements of most of automobile steering columns with different sizes and geometrical shapes can be met.

Description

technical field

[0001] The invention belongs to the technical field of automobile safety and testing, and in particular relates to a fixture, a device and a method for crushing performance testing of steering pipe columns of automobiles. Background technique

[0002] Automobile steering column is an important part of automobile steering system, and its crushing performance is an important technical index to measure the quality of automobile steering column. With the continuous development of automotive electronic technology and automotive safety technology, the functions of automotive steering columns are also increasing. For example, in order for the driver to complete the steering with less effort, an electronic power steering system has appeared; in addition, in order to increase the occupant's living space and energy absorption space during a collision, a collapsible energy-absorbing steering column has appeared. Both of these features improve the performance of the ste...
