Patent number: 11994185Abstract: Provided is a brake device for braking a rotational movement of a shaft about the longitudinal axis, wherein the shaft is mounted so as to be rotatable about the longitudinal axis in a direction of rotation and in a counter direction which opposes the direction of rotation. Brake devices typically use constant and relatively high braking torques, to ensure a controlled movement of a movement portion, braked by the brake device, in every situation. However, this increases the energy consumption for a movement of the movement portion, and the wear of the brake device. A brake device equipped with a setting device for mutually opposing setting of a braking torque on the shaft during rotation of the shaft in the direction of rotation, and a counter braking torque during rotation of the shaft in the counter direction is provided. Also provided is a method for controlling a brake device.Type: GrantFiled: May 5, 2020Date of Patent: May 28, 2024Assignee: STABILUS GMBHInventors: Thomas Reif, Jörg Hillen, Andreas Ritter, Peter Oster
