Embodiment Construction
[0047] figure 1 A schematic plan view of an embodiment of the low-floor vehicle 1 according to the invention is shown, wherein the vehicle is designed as a scooter. The vehicle 1 has a base body 2 which is designed as a tray and which provides a standing surface 3 on the front for a user of the vehicle 1 . On the rear side of the base body 2 opposite the front, exactly two axle bearing units 4 are arranged, which are of double-rail design, that is to say each axle bearing unit 4 contains exactly two wheels 5 . In an embodiment, the wheels 5 are designed as rollers, such as hard rubber rollers or polyurethane rollers. The axle bearing units 4 each have two axle sections 6 , wherein each axle section 6 supports a wheel 5 . The axle bearing units 4 are each connected to the base body 3 via a tilting device 7 . The tilting device 7 allows tilting or swiveling of the axle bearing unit 4 relative to the basic body 2 , so that the vehicle 1 can be driven into corners by shifting t...

The invention relates to a braking system (30) comprising a rotating element (5) rotatable about an axis of rotation (D) and a braking device (10) for braking the rotating element (5), wherein the braking device (10) has a first braking element (13) which can be moved between an idle position, in which an annular braking surface (14) of the first braking element (13) is concentric with the axis ofrotation (D) of the rotating element (5) and is remote from the rotating element (5), and a brake position, in which the braking surface (14) of the first braking element (13) is in contact with therotating element (5) or with a second braking element (9) that is non-rotatably connected to the rotating element (5), wherein: the first braking element (13) can be hydraulically moved between the idle position and the brake position; the first braking element (13) is connected to a tubular brake piston (12) which is mounted in a housing (11) having a tubular inner space (11.1) for receiving a hydraulic liquid; and the first braking element (13) is annular and has first interlocking elements (24), in particular multiple teeth or splines, on an inner contour which interact with corresponding second interlocking elements (23) on an outer contour of the housing (11) in such a way that the first braking element (13) is secured against rotation about the axis of rotation (D) and can be moved parallel to the axis of rotation (D). In addition, the invention relates to an axle support unit (4) for a low-floor vehicle, in particular for a skateboard, comprising a braking system (30) accordingto any one of the preceding claims, wherein the rotating element (5) of the braking system is a wheel, and relates to a low-floor vehicle (1) having such an axle support unit (4). The invention further relates to a drive unit having such a braking system (30).
Description
technical field [0001] The invention relates to a braking system with a rotating element rotatable about an axis of rotation and a braking device for braking the rotating element, wherein the braking device has a first braking an element movable between a rest position and a braking position in which an annular ring of the first braking element is arranged concentrically with the rotary element axis of rotation and away from the rotary element In the braking position, the braking surface of the first braking element is in contact with the rotary element or with a second braking element which is connected to the rotary element in a rotationally fixed manner. Furthermore, the invention relates to an axle bearing unit suitable for low-floor vehicles, in particular for scooters, with at least one wheel rotatable about an axis of rotation and a wheel for braking A braking device, wherein the braking device has a first braking element movable between a rest position and a braking p...
