FIELD: machine building.
SUBSTANCE: present invention relates to a parking brake unit and an electromechanical brake clamp. Parking brake unit comprises: a cylinder body assembly, a cavity having an opening provided in the cylinder body assembly; energy accumulation unit located in the cavity and containing: plate spring cylinder body, plate spring bushing, first plate spring assembly, support part, a second plate spring assembly, arranged between the support part and the cylinder body assembly, and the wedge-shaped part, wherein one end of the wedge-shaped part, located next to its bearing inclined plane, is connected to the bushing of the plate spring, and the other end of the wedge-shaped part passes through the second plate spring assembly and is connected to the support part; resultant thrust control unit; and a blocking unit located between the plate spring cylinder body and the plate spring bushing. Energy of the parking brake unit is generated due to potential energy of elasticity of plate springs in assembly.
EFFECT: improving reliability, increasing efficiency of energy accumulation, compactness.
