The invention provides a taper clutch brake device, and belongs to the technical field of clutches. The taper clutch brake device solves the technical problems that an existing clutch is short in service life, and poor in the stability are solved. The taper clutch brake device comprises a transmission shaft, a driving wheel, a transmission seat, a brake seat and a transmission part, wherein the transmission shaft extends in the axial direction; the driving wheel is arranged on the transmission shaft and is axially fixed with the transmission shaft; the transmission seat is fixedly connected with the driving wheel and can synchronously rotate along with the driving wheel, the transmission shaft penetrates through the transmission seat; the brake seat is fixedly arranged and separated from the transmission seat, the transmission shaft penetrates through the brake seat; and the transmission part is fixedly connected to the transmission shaft in the circumferential direction, the transmission part is located between the transmission seat and the brake seat and is separated from the transmission seat and the brake seat, and the transmission part can axially move relative to the transmission shaft. According to the conical surface-contacted matching structure, so that when the transmission part is in contact with the transmission seat or the brake seat, the force in the radial direction and the axial direction is generated at the same time, the transmission and braking effects are good, the clutch and braking are combined in the whole structure, the structure is simple, and the structure compactness is good.
