The invention relates to the technical field of automobile parts, and provides a giant magnetostrictive type automatic emergency braking device which comprises a supporting part, a driving part, a driving part and a driving part. The brake disc is rotationally arranged on the supporting part; the transmission mechanism is arranged on the frame body; the friction plates are arranged on the transmission mechanism, and the friction plates are distributed on the two sides of the brake disc; according to the automatic emergency braking device provided by the embodiment of the invention, the GMM rod is arranged, and a method for controlling the telescopic deformation of the GMM rod by controlling the current of the electrified coil is adopted, so that during emergency braking, the coil is electrified, a magnetic field is generated, the GMM rod abuts against the push rod and the sliding block when extending, and the sliding block drives the transmission mechanism to move, so that the friction plate and the brake disc are clamped; and emergency braking is achieved.
本发明涉及汽车零部件技术领域,提供一种超磁致伸缩式自动紧急制动装置,所述自动紧急制动装置包括:支撑部,所述支撑部上设有框体;制动盘,所述制动盘转动设置在所述支撑部上;传动机构,所述传动机构设置在所述框体上;摩擦片,所述摩擦片设置在所述传动机构上,所述摩擦片分布在所述制动盘的两侧;本实施例提供的自动紧急制动装置,通过设置有GMM棒,采用控制通电线圈电流来控制GMM棒伸缩形变的方法,在紧急制动时,对线圈通入电流,并产生磁场,GMM棒伸长时会抵住推杆和滑块,滑块带动传动机构进行运动,使得摩擦片和制动盘夹紧,实现紧急制动。
