A system for counting wheel revolutions made by a wheel of a vehicle, the system including an electronic counter, a transmitter, a housing, and a connector. The electronic counter counts a number of wheel revolutions made by the wheel. The transmitter transmits data from the electronic counter to a remote database. The housing houses the electronic counter. The connector removably attaches the housing to a nut anti-loosening device installed on the wheel.

A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.

A controller and a method for controlling casters attached to a movable part such as a hospital bed, for switching the castors between a state in which the castor is pivot locked and rotationally blocked, and a state in which there is neither a pivot locking nor a rotational blocking, additionally switchable into a state in which the caster is only pivot locked, actuatable electrically and also manually, movement sensor. Multiple switching states may be automatically and sequentially assumed in a predetermined sequence, a first switching state in which there is neither a pivot locking nor a rotational blocking, which a second switching state, in which one or more or all castors are pivot locked, however not rotationally blocked, and finally a switching state, in which all switchable casters are again pivot locked and rotationally blocked.

A quick release device for at least partially muscle-powered two-wheeled vehicles, having an axle unit and a clamping mechanism. The axle unit includes an axle extending in the axial direction, a locking device at the first end of the axle unit and a fastener at a second end of the axle unit. The clamping mechanism is suitable for mounting and demounting the axle unit to a two-wheeled vehicle. The clamping mechanism has an operating lever and a clamping component, the latter is non-rotatably coupled with the axle unit and is decoupled from the axle unit. The clamping mechanism has an intermediate device with an actuating unit, which ensures in a first position a non-rotatable connection of the clamping component and the operating lever, and in a second position, allows the operating lever to pivot relative to the clamping component while the clamping component is non-rotatably coupled with the axle unit.

The invention relates to a shield-shaped side-wall protection element for a vehicle tire and to a protective device for vehicle tires. In order to provide a side-wall protection element for vehicle tires that can optimally protect a tire side wall under rough conditions, that can be produced economically, and is easy to install, the invention provides a shield-shaped side-wall protection element for a vehicle tire, comprising a radially inner base, an outer edge, which forms the radially outer end and which extends in a circumferential direction, and with a shield segment, which extends from the outer edge at least to the base, wherein the outer edge is at least partially offset axially inward from the base). The protective device for vehicle tires according to the invention comprises a plurality of shield-shaped side-wall protection elements arranged overlapping in the manner of shingles in a circumferential direction.

The present invention relates to a vehicle (100), in particular a bicycle, for performing tests for a driver assistance system. The vehicle (100) has a base body (101) and at least one strut (102), which is formed to be dimensionally stable without influence of an impact force, which is generatable upon a collision of the vehicle (100) with a collision body, and is elastically deformable upon influence of the impact force. The strut (102) is connected to the base body (101) such that upon influence of the impact force the strut (102) is non-destructively detachable from the base body (101).

A method for producing a wheel disk of a vehicle wheel may involve producing the wheel disk produced from a steel blank by hot forming. The blank may be at least partially hardened, preferably press-hardened, during or after the hot forming. The blank may be hot formed using at least one punch and at least one die, and at least one opening may be introduced into the blank using hot trimming means. At least one opening may be introduced during the hot trimming using at least one trimming bolt and an application bolt, wherein the application bolt may have at least one region having a cross-sectional shape that is variable in a longitudinal direction of the application bolt. Using the application bolt, the at least one opening may be calibrated via the variable cross sectional shape.

The present disclosure relates to caster wheels having a skirt, specifically a skirt which fits over one side of the wheel only, and thus does not interfere with the actuation of a caster wheel locking mechanism.
