Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1: the utility model discloses an electromagnetic brake release mechanism, a serial communication port, by pivot 1, bottom plate 2, brake friction board 3, friction disk clamp plate 4, solenoid controller 5, unblock double-screw bolt 6 and constitute, brake friction board 3 is installed in pivot 1, solenoid controller 5 installs on bottom plate 2, and is equipped with friction chamber 21 between solenoid controller 5 and the bottom plate 2, friction disk clamp plate 4 is arranged in friction chamber 21, unblock double-screw bolt 6 is equipped with the stud head, open stud head inboard has interior hexagonal blind hole, friction disk clamp plate 4 opens has the unblock screw, solenoid controller 5 opens has the spring blind hole of unblock hole 51, opening towards friction chamber 21, pressure disk spring 22 is installed to the spring blind hole, unblock double-screw bolt 6 passes unblock hole 51 and unblock screw meshing from the outside, and the terminal outstanding friction disk clamp plate 4 of unblock double-screw bolt 6, The head of the stud protrudes out of the electromagnetic controller 5, a top piece 7 is installed between the head of the stud and the electromagnetic controller 5, and a clamp spring 8 is clamped at one end of the unlocking stud 6 protruding out of the friction disc pressing plate 4. The top piece 7 is a coil spring. The rotating shaft 1 is provided with a spline sleeve with external teeth, the brake friction plate 3 is provided with internal teeth, and the brake friction plate 3 is fixedly arranged on the spline sleeve by means of gear meshing.
The bottom plate 2, the electromagnetic controller 5 and the friction disk pressing plate 4 form a stator part of the mechanism, the rotating shaft 1 and the braking friction plate 3 form a rotor part of the mechanism, and the braking friction plate 3 contacts the friction disk pressing plate 4 to enable the mechanism to achieve the braking effect. The working principle of the mechanism is that the rotating shaft 1 drives the brake friction plate 3 to rotate in the friction cavity 21, the electromagnetic controller 5 works to absorb the friction disc pressure plate 4 when the electromagnetic controller rotates freely, so that the brake friction plate 3 is not contacted with the friction disc pressure plate 4, the rotating shaft 1 rotates smoothly, and the pressure disc spring 22 is extruded by the friction disc pressure plate 4; when braking is needed, the electromagnetic controller 5 does not work, so that the friction disc pressure plates 4 can be pushed towards the friction cavity 21 by the pressure plate spring 22, the brake friction plates 3 are contacted and rubbed with the friction disc pressure plates 4, the rotation of the rotating shaft 1 is greatly hindered, and finally the rotating shaft 1 stops rotating to achieve the braking effect.
Referring to fig. 2: the top part 7 is a spiral spring, and can act between the unlocking stud 6 and the electromagnetic controller 5 through the self resilience force of the spring, so that the unlocking stud 6 is stably installed, and the unlocking stud 6 can also be stably fixed when a vehicle runs. The circlip 8 may be an E-type circlip. Through the screwing condition of the arranged unlocking stud 6, the position of the friction disc pressing plate 4 in the friction cavity 21 can be directly changed by driving the friction disc pressing plate 4 through the unlocking screw hole structure, and therefore the sensitivity of the mechanism during braking is adjusted. The unlocking stud 6 is prevented from being screwed too deeply to cause the unlocking force generated by the electromagnetic controller 5 to lose the braking effect through the arranged top piece 7, and the arranged snap spring 8 ensures that the unlocking stud 6 is separated from the friction disc pressing plate 4 when the unlocking stud 6 and the friction disc pressing plate 4 are screwed too loosely to cause the unlocking stud 6 to be detached from the friction disc pressing plate 4, and finally the unlocking stud 6 is loosened. Wherein, the tail end of the unlocking stud 6 is provided with a groove specially used for clamping the clamp spring, and the clamp spring 8 is directly clamped on the groove.
The stud head is provided with a butterfly-shaped screwing block 61. The butterfly-shaped screw block 61 is provided to facilitate the user to turn the unlocking stud 6 without relying on other tools, such as a hexagonal screwdriver, by directly pinching the screw block with the hand.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
