Automobile steering column installation structure

Abstract

The invention discloses an automobile steering column installation structure and belongs to the field of automobile manufacture. The automobile steering column installation structure comprises an instrument cross beam, a middle path connecting piece, a steering column installation bracket and a player connecting bracket, wherein the middle path connecting piece is arranged on the middle of the instrument cross beam; the steering column installation bracket is installed on one side of the middle path connecting piece on the instrument cross beam; the player connecting bracket is arranged on the other side of the middle path connecting piece on the instrument cross beam; and the instrument cross beam is fixedly connected with the braking pedal installation bracket of an automobile by virtue of a first bracket, is fixedly connected with the accelerator pedal installation bracket of the automobile by virtue of a second bracket and is fixedly connected with the front baffle of the automobile by virtue of a third bracket between the player connecting bracket and the middle path connecting piece. Three connection structures of the instrument cross beam and an automobile body are additionally arranged in the automobile steering column installation structure in the embodiment of the invention, so that the output frequency of an automobile engine is effectively avoided, and meanwhile, the weight is reduced by about 50% relative to a general design instrument cross beam assembly.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an automobile steering column installation structure. Background technique [0002] The steering column of the steering wheel is generally connected to the instrument beam (Cross Car Beam) through the steering column mounting bracket, and then connected to the vehicle body through the instrument beam. Among them, the vibration of the steering wheel is an important indicator to measure the comfort of the car. In addition to being closely related to its own structure, the structure of the instrument beam also has a great influence on its vibration frequency, mainly due to the output frequency of the engine and the natural frequency of the steering system. Closer, resonance causes jitter. [0003] In order to reduce vibration, the thickness of the plate can be increased to increase the stiffness of the instrument beam; or without major changes, it is a very effective technic...
