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 pallet and which provides a standing surface 3 for the user of the vehicle 1 at the front. On the rear side of the base body 2 opposite the front are exactly two axle support units 4 , which are of a double-track design, ie each axle support unit 4 contains exactly two wheels 5 . In an embodiment, the wheels 5 are designed as rollers, for example hard rubber or polyurethane rollers. The axle support units 4 each have two axle sections 6 , wherein each axle section 6 supports a wheel 5 . The axle support units 4 are each connected to the base body 3 via a tilting device 7 . Said tilting device 7 allows the axle support unit 4 to be tilted or swiveled relative to the base body 2 so that the vehicle 1 can be driven into a corner by the displacement of the drive...

The invention relates to a braking system (30) with a rotating element (5) rotatable about an axis of rotation (D) and a braking device ( 10), wherein said brake device (10) has a first brake element (13) which can move between a rest position and a brake position, in said rest position, in contact with said rotating element ( 5) The annular braking surface (14) of the first braking element (13) is arranged concentrically with the rotation axis (D) and away from the rotating element (5), in the braking position, the the braking surface (14) of the first braking element (13) is in contact with said rotary element (5) or with a second braking element (9) connected to said rotary element (5) in a torsionally fixed manner, Wherein, the first brake element (13) is hydraulically movable between the rest position and the brake position, wherein the first brake element (13) is supported on the housing (11 ), the housing has a hollow cylindrical inner cavity (11.1) for hydraulic fluid, wherein the first brake element (13) is designed as ring-shaped, and have a first type of mating element (24) on the inner contour, in particular a plurality of teeth or wedges, which correspond to a second type of mating element ( 23) Working together, ie said first braking element (13) is locked in rotation about said rotation axis (D), but can move parallel to said rotation axis (D). Furthermore, the invention also relates to an axle support unit (4) suitable for low-floor vehicles, in particular for scooters, with a brake according to any one of the preceding claims. System (30), wherein the rotating element (5) of the braking system is designed as a wheel, and relates to a low-floor vehicle (1) with such an axle bearing unit (4). The invention also relates to a drive unit with such a braking system (30).
Description
technical field [0001] The invention relates to a braking system with a rotary element rotatable about an axis of rotation and a braking device for braking the rotary element, wherein the braking device has a first brake element movable between a rest position and a braking position in which an annular ring of the first braking element is arranged concentric with the axis of rotation of the rotating element and away from the rotating element A braking surface, in the braking position, the braking surface of the first braking element is in contact with the rotating element or with a second braking element connected to the rotating element in a rotationally fixed manner. In addition, the invention relates to an axle support unit suitable for low-floor vehicles, in particular for scooters, with at least one wheel rotatable about an axis of rotation and one wheel for braking the wheel A braking device, wherein the braking device has a first braking element movable between a rest ...
