Abstract

An automobile brake pad thickness detection device disclosed by the invention comprises a plurality of thickness detection heads, each thickness detection head comprises a base, an ultrasonic distance detector, a controller and a protection sleeve, and the base is fixed on a support plate of an automobile brake caliper. The ultrasonic distance detector is fixed outside the base, the detection end of the ultrasonic distance detector faces an automobile brake disc, the outer portion of the ultrasonic distance detector is provided with the protective sleeve, the protective sleeve can horizontally and elastically move between the base and the automobile brake disc, and the ultrasonic distance detector is electrically connected with the controller. The protection sleeve is arranged outside the ultrasonic distance detector of the thickness detection head so that the ultrasonic distance detector is protected, and meanwhile, the deviation detection heads are arranged in a surrounding manner so that whether the abrasion degree of the automobile brake pad is uniform or not is detected in real time during thickness detection.

Description

【Technical field】 [0001] The invention relates to the technical field of brake pads, in particular to the technical field of a thickness detection device for automobile brake pads. 【Background technique】 [0002] Automobile brake pads are a device that decelerates the vehicle through friction. Automobile brake pads will gradually lose thickness due to friction during the working process. If the thickness of the brake pads of the car is insufficient, the friction force will be insufficient, which will cause the brake pedal to feel light, the brakes are hard, or the car cannot be braked. Therefore, people need to often check the wear situation of automobile brake pads to judge whether need to change automobile brake pads. At present, people mainly judge whether it is necessary to replace the brake pads by visual inspection, disassembly measurement, or measuring the degree of wear according to the mileage of the vehicle, which is cumbersome and easy to misjudge. 【Content of...
