In order to ensure the service life and improve the braking effect, the friction disc 1 is made of a high-temperature-resistant and wear-resistant friction material.
In order to improve the magnetic isolation effect, the magnetic isolation ring 9 is made of copper.
The working principle is as follows: when the electromagnetic coil A11 installed on the electromagnet A10 is electrified, an electromagnetic field is generated around the memory alloy rod 12, so that the memory alloy rod 12 is excited to generate displacement deformation, the memory alloy rod extends in the axial direction, the magnetic isolation ring 9, the magnetic ring 8, the guide rod 3 and other parts are pushed to the right, the friction disc 1 is pushed to the surface of the brake disc, and the brake disc is pressed through the friction disc 1 to brake. At the same time, when the electromagnetic coil B4 attached to the electromagnet B5 is energized, a magnetic field attracting the magnet ring 8 is generated around the electromagnet B5, and the magnet ring 8 is attracted to the right. Due to the existence of the magnetism isolating ring 9, the magnetic attraction force generated by the electromagnet A10 is far smaller than the magnetic attraction force generated by the electromagnet B5 on the magnetic ring 8. Therefore, when the electromagnet B5 and the electromagnet a10 are both energized, the magnetic ring 8 has the overall magnetic attraction force directed to the right, and in this case, the friction disc 1 performs the braking function on the brake disc by the dual action of the deformation of the memory alloy rod 12 and the rightward movement of the magnetic ring 8. Under the condition that the electromagnetic coil A11 and the electromagnetic coil B4 are powered off, the spring 6 generates return elastic force, so that the memory alloy rod 12 is restored to the original shape and the rod length is restored to the original shape; on the other hand, the magnetic ring 8 is pushed to move leftwards, and then the friction disc 1 is driven to move leftwards and leave the brake disc, so that the brake releasing function of the brake disc is realized.
When the brake is actually used, the two magnetic control brakes are symmetrically arranged and arranged on two sides of the brake disc, so that the brake or the brake release operation can be realized through synchronous action in work.
The electromagnet A is arranged in the large-diameter section in the stepped cavity, so that the electromagnet A can be axially limited through the large-diameter section; the memory alloy rod made of memory alloy is arranged in the axial through hole A of the electromagnet A, so that the memory alloy rod can be promoted to extend in the axial direction when the electromagnet A generates a magnetic field; the electromagnet B is arranged at the right end of the small-diameter section, the magnetic ring is arranged on the left side of the small-diameter section, the left end of the guide rod which is arranged in the axis through hole B in a sliding mode and penetrates out of the shell in a sliding mode is fixedly connected with the magnetic ring, and the magnetic ring can be adsorbed to the right side when the electromagnet B has a magnetic field; so that the guide rod can extend to the right side to drive the friction disc to perform braking action; through the arrangement of the spring, the magnetic ring and the memory alloy rod can be conveniently reset after the magnetic field disappears. In the utility model, the magnetic control memory alloy material technology is applied to the brake, and under the braking working condition, the double braking function of the magnetic control memory alloy and the magnetic control soft magnetic material can be realized, so that the braking process can be quicker. Meanwhile, in the brake releasing process, the elastic action of the spring on the magnetic ring and then on the magnetism isolating ring is adopted, so that the memory alloy rod is quickly restored, and the quick restoration of the magnetic ring, the guide rod and the friction disc can be promoted, so that the spring can have a double-restoration function. In addition, because of the adoption of magnetic control memory alloy and magnetic control soft magnetic materials, the brake has a double-insurance function, and can still complete an effective braking function even under the condition that a magnetic field is out of control or fails.
