Brake device and vehicle

Abstract

The invention belongs to the technical field of braking, and discloses a braking device and a vehicle. According to the braking device, the elastic adjusting structure is arranged between the limiting structure and the limiting part of the shell. In the axial direction of the lead screw, the elastic restoring force of the elastic adjusting structure can drive the limiting structure to be away from the friction plate structure in the axial direction of the lead screw, and the two ends of the force transmission structure can abut against the first stress face of the limiting part and the second stress face of the lead screw correspondingly. The limiting structure is an output end of the transmission mechanism or a lead screw. At least the part, making contact with the limiting structure, of the elastic adjusting structure can synchronously rotate along with the limiting structure. Therefore, the phenomenon that a friction plate structure drags a brake disc in a non-braking state in the prior art can be avoided, the phenomenon that the distribution positions of a force transmission structure and a ball screw mechanism in the axial direction of a lead screw are not fixed due to abrasion in the operation process can be avoided, and the phenomenon that a lubricating pad and / or a compression spring are / is replaced in the prior art can be avoided. And the working stability, the braking precision and the service life of the braking device are improved.
