Problems solved by technology
[0002] Due to its good thermal stability, quick response, easy maintenance and other advantages, disc electric brakes are used in construction machinery, elevators and other moving machinery equipment. However, the existing disc electric brakes have the following defects. First, The bulkiness or length of the brake assembly, thus making it difficult to accommodate the vehicle space that would have been available in the past for non-electrohydraulic brakes; second, the brake mechanism must be arranged to be operable under brake applied load, especially during deformation of the caliper brake body. Deformation can lead to misaligned loads applied to the brake mechanism, which can lead to sticking or wear, resulting in premature failure; third, when the disc electric brake is braking, it often occurs because the brake is not locked. The phenomenon that the machine cannot work stably

The invention discloses a self-locking operating mechanism brake, comprising a brake main body, the brake main body comprises a hollow shell main body and an open caliper, the head of the caliper is fixedly provided with a fixed braking part, and the tail of the caliper is installed with a fixed brake The inner space between the shell body and the tail of the caliper is the brake cavity, and the brake cavity is coaxially arranged with a sleeve along the axial direction, the axial end of the sleeve is suspended, and the sleeve The axial head end is fixedly installed on the caliper; the self-locking operating mechanism brake of the present invention further includes an electromagnetic drive device, the electromagnetic drive device includes a stator and a rotor, and a permanent magnet is arranged on the outer side wall of the rotor. The self-locking control mechanism brake of the present invention has a compact structure between each component, the braking is realized by the planetary roller screw pair, and the planetary roller screw pair can realize self-locking, which effectively prevents the reverse axial direction. sports.
Description
technical field [0001] The invention belongs to the field of brakes, relates to a self-locking operating mechanism brake, in particular to a self-locking operating mechanism brake. Background technique [0002] Due to its advantages of good thermal stability, fast response, and easy maintenance, disc electric brakes are used in construction machinery, elevators and other sports machinery and equipment. However, the existing electric disc brakes have the following defects. First, The bulk or length of the brake assembly makes it difficult to accommodate the vehicle space that used to be available for non-electro-hydraulic brakes; second, the brake mechanism must be arranged to operate under the applied load of the brake, especially during deformation of the caliper brake body. Deformation can result in misaligned loads applied to the braking mechanism, which can lead to seizure or wear, resulting in premature failure; The phenomenon that the machine cannot work stably.
