Intelligent brake capable of realizing smooth braking

The utility model relates to an intelligent brake capable of realizing smooth braking. The intelligent brake comprises a normally-closed electro-hydraulic brake and an intelligent drive. The normally-closed electro-hydraulic brake comprises a driving motor, an electro-hydraulic push rod, a support, a brake disc, a braking friction material and a braking spring. The intelligent drive comprises a frequency converter, a contactor, a time relay, an intermediate relay, a power frequency variable selector switch, a remote braking switch, a remote sudden stop switch, a power frequency indicator lamp, a variable-frequency indicator lamp, a circuit breaker and a fuse. The intelligent brake enables the braking process (especially the sudden stop process) to be smooth, impact during braking can be relieved, and a transmission chain can be protected. Energy absorption during braking is realized, namely the brake is enabled to have the damping function to completely absorb system kinetic energy. The intelligent brake is a
