A method for preventing a collision between sections of a test bench (3), which are movable relative to one another, of a test bench system (1) is illustrated and described, the method comprising the following steps: providing a simulation model (19) which represents the test bench (3) and the sections, which are movable relative to one another, of the test bench (3), determining a desired value for a movement of a first section of the test bench (3), moving a simulated first section, which represents the first section of the test bench (3), on the basis of the determined desired value, determining a distance between the simulated first section and a simulated second section of the test bench (3), wherein the simulated second section represents a second section of the test bench (3), comparing the determined distance with a predefined minimum distance and, whenever the determined distance is equal to or greater than the predefined minimum distance, moving the first section of the test bench (3) on the basis of the determined desired value. In addition, a corresponding test bench system, a computer program and a computer-readable storage medium are illustrated and described.

Abrégé

A locking device (1) for a drive shaft (2) of a bicycle includes a radially outwardly extending, disk-shaped portion (3) non-rotatably mountable on the drive shaft (2). The radially outwardly extending, disk-shaped portion (3) has at least one groove (5) in a radially outer edge region (4). The locking device (1) also includes a locking element (6) arranged adjacently to the radially outer edge region (4) and an actuatable shift element (7) mechanically operatively connected to the locking element (6). The shift element (7) is actuatable to bring the locking element (6) into interlocking connection with the at least one groove (5) in order to lock the drive shaft (2).

Abrégé

The invention relates to a method and a fluid flow device for a vehicle which is at least partly electrically powered and to such a vehicle. The vehicle has an electric axle and at least one additional unit which are to be cooled and/or heated, in particular during the operation of the vehicle, wherein the fluid flow device forms a common fluid circuit in order to cool and/or heat the electric axle and the at least one additional unit, and the fluid circuit is designed to conduct an electrically conductive or non-electrically conductive fluid and/or comprises such a fluid which is designed to absorb and dispense thermal energy.
