Die casting magnesium alloy steering column support

Abstract

The invention discloses a die casting magnesium alloy steering column support which comprises a mounting slot for mounting an adjusting mechanism. Racks are arranged on two sides of the mounting slot, and a boss is arranged on the periphery of the mounting slot and higher than the racks. The magnesium alloy steering column support is formed by die casting once and is high in specific stiffness and impact resistance, the requirement on light weight can be met by the aid of the lightest metal structure material magnesium alloy (1.8g / cm<3>), the racks are directly cast on the steering column support, and assembly errors are eliminated, so that the cost of a part assembly is reduced. By the aid of the boss which is arranged on the periphery of the mounting slot and higher than the racks, on one hand, the adjusting stroke of the steering column adjusting mechanism is decreased, and adjusting precision of the steering column adjusting mechanism is ensured; on the other hand, the mechanical strength of the mounting slot is enhanced.

Description

technical field [0001] The invention relates to a steering wheel steering column bracket, in particular to a die-casting magnesium alloy steering column bracket. Background technique [0002] The structure of the steering system of modern automobiles is various, but all of them include steering control mechanism, steering gear, steering transmission mechanism and steering electronic control system. The steering column is the core component of the steering mechanism of the car. Its basic function is to transmit the steering force of the driver's steering wheel to the steering gear, and finally control the driving direction of the car wheels. With the rapid development of the automobile industry, the driving comfort and safety requirements for the steering column are increasing day by day. On the one hand, the steering column should have the function of adjusting the position of the steering wheel to facilitate the manipulation of drivers of different sizes; The ability of t...

AI Technical Summary

Problems solved by technology

[0004] There is still such a problem in the steering column bracket adopting steel plate stamping or aluminum alloy casting: it is necessary to assemble a rack made of plastic material in the later stage to realize the adjustment of the working angle and height of the steering wheel within a certain range

The rack assembled in the later period is not very ideal in terms of strength and other aspects, and the assembly process is increased. When the steering column adjustment mechanism is installed later, the error caused by the assembly of the rack is difficult to eliminate, which affects the accuracy of the steering column adjustment.
