Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of brake pad steel back, especially relates to a brake pad steel back. BACKGROUND

[0002] As an indispensable key component of brake pad, brake pad steel back bears the basic but crucial support function in the vehicle braking process. Brake pad realizes the deceleration and stop operation of the vehicle by relying on friction force through close contact with brake disc (drum), and steel back is the "behind-the-scenes hero" that provides solid physical support for friction material. From the early start of the automobile industry to the vigorous development of various motor vehicles today, brake pad steel back has always been closely connected with the advantages and disadvantages of vehicle braking performance, and its technical evolution accompanies every step of automobile technology innovation.

[0003] The applicant found that a "brake pad structure" was disclosed in a Chinese patent with publication (announcement) number "CN211175145 U". The patent mainly sets a boss on one side of the combination surface of the brake pad steel back and the friction material. When the brake pad and the brake disc are worn to the limit position, the boss contacts and rubs with the brake disc, thereby emitting a friction acoustic alarm sound to prompt the driver to replace the brake pad. However, the patent cannot continuously provide effective support through the nested steel back inside when the steel back is worn to a certain extent, ensuring the normal operation of the brake pad. Therefore, in the actual use process, the entire brake pad may need to be replaced once the outer steel back is worn to a certain extent, thereby increasing the replacement frequency of the brake pad. For this reason, the utility model provides a brake pad steel back. UTILITY MODEL CONTENTS
