Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to an automobile electronic mechanical brake. Background Art

[0002] The automobile braking system refers to a special braking mechanism installed on the automobile in order to technically ensure the safe driving of the automobile and increase the average speed of the automobile. Generally speaking, the automobile braking system includes two independent devices, the driving brake device and the parking brake device. The driving brake device is operated by the driver's foot, so it is also called the foot brake device. The parking brake device is operated by the driver's hand, so it is also called the hand brake device. The automobile caliper is part of the foot brake device. It transmits the braking force to the wheel by mechanical means, thereby slowing down or stopping the movement of the vehicle. The caliper is an important component in the braking system. In the disc brake system of modern automobiles, the brake caliper is usually installed next to the wheel and fixed to the wheel suspension system. When the driver steps on the brake pedal, the brake fluid is transmitted to the piston inside the caliper through the brake pipe, pushing the brake pad to contact the brake disc, generating friction.

[0003] In the current electronic mechanical brakes used in automobiles, when the calipers are in use, when the brake pads rub against the brake pads in the calipers for a long time, it is easy to cause excessive heat. The high temperature will accelerate the wear of the brake pads, resulting in a reduction in the thickness of the brake pads, thereby reducing the braking effect. At the same time, the current brake pads are not easy to disassemble and maintain during use, which reduces convenience. Utility Model Content
