BRAKE APPARATUS AND AUTOMOBILE

This application relates to a brake apparatus. The brake apparatus is connected to a rotating part (A). The brake apparatus includes a housing (1) connected to the rotating part, a brake part (2), a transmission part (3), a drive part (4), a gain mechanism (5), and a compensation mechanism (53). The drive part drives, by using the transmission part, the brake part to move along a direction close to or away from the rotating part for braking and braking release. A moving member (531) of the compensation mechanism (53) is connected to the gain mechanism (5), and a transmission member (532) of the compensation mechanism is connected to the drive part (4), to drive the gain mechanism to move along a direction close to the brake part. Such a design improves resetting efficiency of the brake part, and compensation is performed by using a mechanical structure, which helps simplify a structure of the brake apparatus and better meets an actual use requirement.
