A brake assembly based on anti-travel self-locking

This invention discloses a brake assembly based on reverse stroke self-locking, including an axle that mates with a wheel and a brake disc mounted on the axle for braking, and a piston driver that drives brake friction blocks to brake the brake disc. These are the main components of a conventional train braking device. In this invention, the brake friction blocks are arranged in two sets symmetrically at both ends of the brake disc, and braking is achieved through a braking mechanism. The braking mechanism outputs a reverse stroke self-locking degree of freedom to the brake friction blocks. This invention, through the mechanical linkage and cooperation between multiple braking mechanisms, provides a reverse stroke braking torque during practical application, increasing the friction between the brake friction blocks and the wheel, maintaining the stability of the brake caliper, and preventing brake slack. This improves the overall braking efficiency and safety of the train, and reduces the failure rate and maintenance costs of the braking system.
