Abstract

The invention relates to a car brake pad abrasion thickness detecting structure and a car brake pad active returning structure. A first end of a first rod body of the car brake pad abrasion thicknessdetecting structure is fixedly connected with a first pole plate, a second end of a second rod body is fixedly connected with a second pole plate, a second end of the first rod body is fixedly connected with a first brake pad on a first side of a brake disc, and a second end of the second rod body is fixedly connected with a second brake pad on a second side of the brake disc. When the car brake pad abrasion thickness detecting structure is used for car braking, due to the thickness abrasion of the first brake pad and / or the second brake pad, the rotating angles of the first rod body and the second rod body are changed, the opposite area between the first pole plate and the second pole plate is changed, and therefore the capacitance values of the first pole plate and the second pole plateare changed. Thus, the thickness abrasion loss of the first brake pad and / or the second brake pad can be judged according to the capacitance values of the first pole plate and the second pole plate, and the effect of detecting the thickness abrasion loss of the first brake pad and / or the second brake pad in real time is realized.

Description

technical field [0001] The application relates to the field of intelligent driving control, in particular to a structure for detecting the wear thickness of an automobile brake pad and an active return structure for an automobile brake pad. Background technique [0002] Automobile brake pads, also known as automobile brake pads, refer to the friction material fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction pad in it are subjected to external pressure and produce friction to achieve the deceleration of the vehicle. Purpose, therefore, during the working process, the thickness loss of the car brake pads will be serious due to friction. If you feel that the brake pedal is light, or you feel that the brakes are hard, and you can't stop the car, it may be that the thickness of the car brake pads is not enough, resulting in friction. If the force is insufficient, it needs to be replaced in time, otherwise it will cause an acciden...
