Abstract: 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.

Abstract: A spindle drive apparatus includes a spindle, a spindle nut, a drive assembly with a drive unit, which is adapted for driving the spindle or the spindle nut, an output shaft of the drive unit and a drive assembly housing, in which the drive assembly is housed, at least one bearing, a coupling element, which prevents a displacement of elements houses therein from each other, wherein the drive assembly housing is free from forces, which are transmitted from one of the superordinate assemblies through the spindle drive apparatus to the other of the superordinate assemblies.

Abstract: A drive device has a spindle drive having a threaded spindle and a spindle nut arranged on the threaded spindle. The spindle drive is configured to drive a first component element and a second component element so as to be axially movable relative to one another. The spindle drive is reversibly rotatably drivable around an axis of rotation extending coaxial to the threaded spindle by a rotatably driven driveshaft arranged in a housing so as to be fixed with respect to rotation. A brake device prevents axially relative movement of the first component element and second component element relative to one another through axial application of force to the first component element and/or second component element.

Abstract: A rotary drive device includes a housing element, a drive shaft and a driven shaft, both rotatably mounted in the housing element, a transmission device that transmits torque from the drive shaft to the driven shaft, and a braking device configured to counteract rotation of the drive shaft. The braking device includes a drive shaft input element, a braking element connected to the housing element for conjoint rotation, and a coupling element adjustable with respect to the input element. A braking force exerted by the braking device is greater when the coupling element is located in a first position than when located in a second position, and the coupling element assigned to the driven shaft so that adjustment from the first position to the second position is triggered by exceeding a threshold value of the difference in torque between the drive shaft and the driven shaft.
