A high-precision vehicle steering gear bracket and its manufacturing method

Abstract

The invention discloses a high-precision automobile steering gear bracket and a manufacturing method thereof. The steering gear bracket comprises a fixing base, a mounting base and a connecting plate, wherein a rotary table is mounted in the fixing base; locking screw rods are connected to the rotary table; a U-shaped connecting piece and screw holes are connected to the side surface of the mounting base; a mounting groove is formed in the U-shaped connecting piece; a hydraulic oil cylinder is arranged in the connecting plate; a piston rod is connected to the hydraulic oil cylinder; and a press block is connected to the piston rod. The manufacturing method of the steering gear bracket comprises the following steps of (1) designing the structure of the steering gear bracket; (2) performing sample test; (3) performing simulated die-casting on the steering gear bracket; (4) performing simulated die-casting; and (5) performing die-casting of the steering gear bracket. Compared with the prior art, mechanical analysis of models and mechanical test of real objects are respectively performed on the steering gear bracket disclosed by the invention, so that mechanical defects of a conventional steering gear bracket are thoroughly rejected, all the mechanical requirements are met, the quality of products is improved, and the steering gear bracket disclosed by the invention has tremendous potential economic value.

Description

technical field [0001] The invention relates to the field of steering gear brackets, in particular to a high-precision vehicle steering gear bracket and a manufacturing method thereof. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, cars have gradually entered thousands of households, providing great convenience for people's travel. The steering gear is an important part of the car. The function of the steering gear is to properly transform the steering torque and steering angle from the steering wheel (mainly deceleration and torque increase), and then output it to the steering rod mechanism, so that the car turns, which belongs to deceleration. transmission. [0003] The steering gear is generally installed through the steering gear bracket, which is used to support and fix the steering gear; in actual use, it is found that for some steering gears with a large lateral offset in the center of th...

Problems solved by technology

[0003] The steering gear is generally installed through the steering gear bracket, which is used to support and fix the steering gear; in actual use, it is found that for some steering gears with a large lateral offset in the center of the steering wheel, the straight rod of the steering gear needs to be bent a lot Amplitude, poor reliability of steering system

For trucks, due to the increase of the load of the whole vehicle, the alternating moment borne by the steering gear bracket increases, and the existing steering gear bracket is prone to cracking, which is very dangerous

At the same time, the existing steering gear brackets are only installed with bolts. During long-term driving, the bolts are prone to loosening due to vibration and other reasons. The firmness needs to be improved and the safety is poor.
