Abstract
A brake may include a bellows having an opening that leads into the interior of the bellows, a brake element joined to the bellows, a rotational element arranged at a distance from the brake element, a fluid reservoir or a pressure production unit, and a first conduit between the fluid reservoir or the pressure production unit and the opening.
Claims19
A brake, comprising:
- a bellows comprising an opening that leads into the interior of the bellows,
- a brake element coupled to the bellows,
- a rotational element arranged at a distance from the brake element,
- a fluid reservoir or a pressure production unit, and
- a first conduit between the fluid reservoir or the pressure production unit and the opening of the bellows,
- a switching unit configured to control a fluid flow between the between the fluid reservoir or pressure production unit and the opening of the bellows via the first conduit, and
- a housing that contains the fluid reservoir, the switching unit, and the first conduit.

An actuation unit, comprising:
- a housing,
- a bellows arranged on the housing or which forms a part of the housing, the bellows comprising an opening that leads into an interior of the bellows,
- a fluid reservoir or pressure production unit arranged in the housing or which forms a part of the housing,
- a conduit arranged in the housing or which forms a part of the housing, wherein the conduit connects the fluid reservoir or the pressure production unit and the opening or wherein the conduit is a part of a conduit system to which the fluid reservoir or the pressure production unit and the opening are connected, and
- a switching unit configured to control a fluid flow between the between the fluid reservoir or pressure production unit and the opening of the bellows via the conduit,
- wherein the switching unit is arranged in the housing.
3 more elements
An actuation unit, comprising:
- a braking element;
- an expandable bellows coupled to the braking element and defining an expandable interior volume,
- at least one of a fluid reservoir or a pressure production unit arranged within the bellows,
- a valve arranged within the bellows and configured to control a fluid flow between the at least one of the fluid reservoir or pressure production unit and the expandable interior volume of the bellows to control an expansion of the bellows and thereby control a movement of the braking element.
