Abstract

The invention provides a ring gear of a soft-magnetic auto antilock breaking system and a preparation method thereof. According to weight percentage, the adopted materials are as follows: 0 to 0.02 percent of C, 0 to 0.05 percent of Cu, 0.4 to 0.5 percent of Ni, 0.5 to 0.7 percent of zinc stearate, 0.3 to 0.4 percent of S, 0.2 to 0.25 percent of P, and the rest is Fe. The ring gear of the soft-magnetic auto antilock breaking system of the invention has steady signals and high sensitivity when matching with a sensor; besides, the invention has the advantages that production material can be saved; high production efficiency and low energy consumption can be realized; material utilization rate can be increased from 40 to 50 percent of traditional production to more than 95 percent; energy consumption can drop by 40 to 70 percent; working hours can drop by more than 50 percent; labor productivity can increase by 10 times or more than dozens of times, etc.

Description

technical field [0001] The invention relates to a sensing signal component of an automobile braking anti-lock braking system. Background technique [0002] The ring gear of the automobile anti-lock braking system is a key component reflecting the sensitivity, and its performance will directly affect the normal operation of the anti-lock braking device of the automobile braking system. [0003] The ring gear of the anti-lock braking system includes an annular disc and teeth arranged on the upper part of the annular disc. At present, the ring gears are all made of No. 20 seamless steel pipes. The preparation methods include: steel pipe cutting, turning, gear hobbing, post-processing and surface treatment. The processing efficiency is low, waste materials, and the output signal is not good. Stablize. As disclosed in Chinese Patent Application (Patent) No.: 200410067782.7, this patent mainly uses AL6061 alloy. [0004] Chinese patent application (patent) number: 03248527.1 re...
