Problems solved by technology

[0002] The hydraulic brake device has a wide range of applications. Generally, it adopts a normally closed brake method. The hydraulic brake device used in conjunction with the cycloid hydraulic motor drive can be used independently. Close to Φ150mm, such as the applicant's BK2-1 hydraulic brake device, which is much larger than the shape of the cycloidal motor connected to it, and uses ball bearings to support the brake shaft. Due to its large radial dimension, it is directly driven by the cycloidal hydraulic motor. The installation of the hydraulic system may not match, which is not conducive to the market demand for compact structure and high overall cost performance, especially the need for a cycloidal hydraulic motor similar to the connection method and external dimensions cannot be met, such as the SAE A of the 2000 motor of the American EATON company Two-hole spigot Φ82.55mm connection method, or SAE A 2-hole spigot Φ82.55mm connection method of the applicant's BMSY, BMR and other motors
