Document Type and Number:
WIPO Patent Application WO/2023/040178
Kind Code:
A1
Abstract:
A brake and a friction disk (130). The brake comprises a yoke iron core (110), a first movable plate (120), a friction disk (130), a first coil (140), a second coil (141), an armature (150), and an elastic member (160), wherein the yoke iron core (110) is provided with a first mounting space (111) and a second mounting recess (112) which are concentrically distributed in sequence from inside to outside, the first mounting space (111) passing through a central position of the yoke iron core (110) in an axial direction of the yoke iron core (110), and the yoke iron core (110) is further provided with at least one third mounting recess (119) that is coaxially arranged with the second mounting recess (112); the first movable plate (120) is located in the first mounting space (111); the friction disk (130) is arranged in the first mounting space (111) and located on the side of the first movable plate (120) close to a second shaft end; the first coil (140) is arranged in the second mounting recess (112); the second coil (141) is arranged in the third mounting recess (119); the armature (150) is connected to the first movable plate (120) by means of a connecting member (180); and the elastic member (160) has a pre-tightening force that enables the armature (150) to be away from the yoke iron core (110). The brake is thin in terms of thickness, and the friction disk (130) is of a separated structure and comprises a plurality of friction units (10). In the friction disk (130), in addition to two surfaces that can serve as working faces to generate a friction braking force, an outer peripheral face can also serve as a working face to provide an additional friction braking force.
