Description

Technical Field

[0001] The utility model relates to the technical field of brake pad performance detection, in particular to a detection device for automobile brake pads. Background Art

[0002] Brake pads are also called brake leather or brake shoes. Vehicles can only travel on the road because of the rotation of the wheels. When the vehicle needs to stop, friction occurs between the brake pads and the brake disc or brake drum, and the kinetic energy of the vehicle is converted into heat energy and consumed during the friction process. In the vehicle's braking system, brake pads are one of the most critical safety parts. The performance of brake pads plays a decisive role in the braking effect. Because during braking, the brake disc or brake drum will be squeezed, causing the brake disc or brake drum to deform. In order to ensure the factory quality of the brake disc or brake drum, a detection device for automobile brake pads is needed.

[0003] After searching, the patent with publication number CN112014251A discloses a compressive hardness detection device for a composite lubrication drum brake pad, which includes a driving mechanism and a pressure-bearing mechanism. When the driving column moves, the driving ring-stage disk contacts the inner cavity edge of the inner limit soft cavity, and the inner cavity edge of the inner limit soft cavity restricts it. When the pressure intensity is large enough, the driving ring-stage disk can penetrate the inner cavity of the inner limit soft cavity, and the driving ring-stage disk cannot return to the initial position at this time. While the driving column is pressing, the bottom end surface of the pressing base is fitted with the upper end surface of the brake pad, and the brake pad is pushed by its pressing thrust for compressive hardness detection. When the bending degree of the brake pad is less than or equal to 175 degrees, the driving column stops pressing, and reads which mechanism of the first grading mechanism, the second grading mechanism, the third grading mechanism and the fourth grading mechanism the uppermost driving ring-stage disk is at the lower end. The accurate number of the compressive hardness of the brake pad is calculated through the preset value.

[0004] Existing equipment estimates the compressive hardness value of brake pads through mechanical structures. Since manual estimation may result in data errors and reduce detection accuracy, we have proposed a detection device for automobile brake pads to solve the above problem. Utility Model Content
