The invention relates to an actuating device for an internal shoe brake, including an automatic adjusting device with an adjusting lever which includes a guide track in the form of a guiding slot with two opposing track surfaces which cooperate with opposing sides of a housing-fixed guide element in order to convert a displacement of the adjusting lever relative to the housing-fixed guide element into pivoting movements of the adjusting lever.

A caliper brake for braking a moving component, including a housing and two brake shoes, which are movable within the housing toward the component to be braked, and a bearing part, which is movable within the housing by an actuator. The brake shoes each have a wedge surface on a side facing away from the component to be braked, by which a braking force acting on the bearing part is transmitted to the brake shoes with deflection and force multiplication. For higher braking forces using a spring-actuated brake, and to reduce the effects of spring travel on the braking force, the bearing part has offset bearing locations against which the wedge surfaces of each brake shoe bear. The wedge surfaces each have, in the region of the bearing locations, a step which is overcome during a closing movement of the brake shoes before they engage the component to be braked.

Also included is a plurality of brake members operatively coupled to the hoisted structure, each of the brake members having a brake surface configured to frictionally engage the guide rail, the brake members moveable between a braking position and a non-braking position. Further included is a plurality of electronic brake member actuation mechanisms operatively coupled to the brake members and configured to actuate the brake members from the non-braking position to the braking position. Yet further included is a load sensing device operatively coupled to the hoisted structure, the load sensing device configured to detect a weight of the hoisted structure, wherein the load sensing device is in operative communication with the electronic brake member actuation mechanisms, wherein the number of actuated mechanisms is dependent on the weight of the hoisted structure.

A braking system for a vehicle includes an indicator device provided to reliably indicate a state of a parking brake of the system, while being simple, convenient, and economical. The system includes a body that delimits a service brake pressure chamber and/or a parking brake pressure chamber, a parking brake movable relative to the body, an unlocking part for unlocking the parking brake connected to the parking brake pressure chamber and accessible from outside the body, and a parking brake indicator device. The indicator device is configured to receive a position of the unlocking part via a state pipe and an indicator of supply and/or the venting of the service brake pressure chamber and/or of the parking brake pressure chamber. This information is processed in to detect and indicate an engaged state or a disengaged state of the parking brake.

Aspects of the technology relate to a braking assembly for a lateral propulsion system of a high altitude platform (HAP) configured to operate in the stratosphere. Power is supplied to a propeller assembly as needed during lateral propulsion so that the HAP can move to a desired location or remain on station. When lateral propulsion is not needed, power is no longer supplied to the propeller assembly and it may slowly cease rotating. However, in certain situations, it may be necessary to cause the propeller assembly to stop rotating as soon as possible. This can include an unplanned descent. Rapid braking can avoid the propeller blades from entangling in the envelope, parachute or other parts of the HAP. A reusable brake is employed to prevent uncontrolled rotation of the propeller on descent, or otherwise to prevent the propeller from spinning freely when not being used to propel the HAP laterally.
