Abstract
The utility model discloses a disk brake with positive pressure being monitored in real time. The disk brake with positive pressure being monitored in real time comprises a shoe, a shoe base, a disk spring base, a brake body, a sensor, a disk spring guide rod, an oil cylinder, an oil cylinder cover, a disk spring assembly, a linkage bolt, a tension spring, a limiting guide sleeve, a connection bolt and the like. The shoe is installed on the shoe base through pressing plates located on the two sides. The disk spring assembly is installed in the disk spring base. Through the guiding of the disk spring guide rod, one end of a disk spring pressing ring tightly presses a disk spring, and the other end of the disk spring pressing ring is tightly attached to the bottom of the oil cylinder. When the disk spring base conducts piston motion in the cylinder, a disk is ejected through a piston, and then the disk spring base is pulled through the connection bolt, so that the disk spring assembly is compressed; at the same time, the linkage bolt pulls the shoe base rightwards, the shoe is released, the tension spring recovers meanwhile, so that the disk spring base has the leftward movement tendency, the left end of the sensor is not pressed, and the stress borne by the sensor is zero. During brake, the movement direction is opposite, the pressure borne by the sensor is increased to the maximum positive pressure value from zero, and therefore brake is achieved.
