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.

Dependent claims

A brake device for braking a rotational movement of a shaft about a 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 of rotation which opposes the direction of rotation,

a) at least one brake disc which is connected to the shaft by free wheel and which is configured to cooperate with a thrust washer in order to generate a braking torque on the shaft, wherein the free wheel couples the brake disc to the shaft in the event of a rotation of the shaft in the direction of rotation, and decouples it from the shaft in the event of a rotation of the shaft in the counter direction of rotation;
and
b) at least one counter brake disc which is connected to the shaft by a counter free wheel and which is configured to cooperate with a counter thrust washer order to generate a counter braking torque on the shaft, wherein the counter free wheel couples the counter brake disc to the shaft in the event of a rotation of the shaft in the counter direction of rotation, and decouples it from the shaft in the event of a rotation of the shaft in the direction of rotation;
and
c) at least one setting device for setting the braking torque and the counter braking torque in a mutually opposing manner.
