steering column

Abstract

The disclosure provides a steering column, which belongs to the technical field of steering columns. The steering column includes a column body and a clamping assembly. The column body includes a steering shaft, an upper column and a lower column. The first end of the upper column is fitted on the first end of the lower column. The two ends of the steering shaft are respectively It is rotatably inserted in the upper pipe string and the lower pipe string. There is a bar-shaped notch on the side wall of the upper pipe string. The bar-shaped notch extends from the first end of the upper pipe string to the upper pipe along the axial direction of the upper pipe string. In the middle of the column, there are limit teeth on the inner wall of the middle part of the bar-shaped notch, and a column pin is provided on the outer peripheral wall of the lower column. The column pin is inserted in the bar-shaped notch and is located at the first end of the upper column. The column pin and the bar The inner wall of the notch is in contact with each other, two clamping plates are arranged on the outer peripheral wall of the upper pipe column, and the clamping assembly is configured to clamp the two clamping plates. The steering column provided by the present disclosure can stably absorb part of the impact energy in the driver's secondary collision.

Description

technical field [0001] The present disclosure belongs to the technical field of steering column, and in particular relates to a steering column. Background technique [0002] With the rapid development of automobile technology, safety regulations have higher and higher requirements for automobile safety. Most of the existing automobile steering columns have energy-absorbing structures. When the front of the vehicle is hit violently, the driver will collide with the steering wheel due to inertia. It is used to absorb part of the impact energy in the secondary collision, so as to protect the driver to a certain extent. [0003] In related technologies, the collapse energy-absorbing structure of the steering column adopts an injection pin-pull-off block structure, that is, the injection pin is used to connect the pull-off block to the upper bracket of the steering column, and the pull-off block is fixedly connected to the crossbeam of the instrument panel. When a collision oc...

Problems solved by technology

[0004] However, the fractured plastic pin and the steering column will fall downward, causing the steering column to separate from the driver, causing the energy absorption of the steering column to suddenly drop to zero. This sudden change will cause the steering column to be unstable. absorb energy
