In a device for releasably securing an additional wheel (2) to a vehicle wheel (1) there is at least one clamping device (3) by means of which the additional wheel (2) can be clamped against the wheel (7) via a spacing sleeve (10). The clamping device (3) has a securing component (13) which is secured to the rim (4) of the wheel (1) by means of a wheelbrace (6) and has an aperture (18) with a through-hole (20) with a waist (19). Into the aperture (18) in the securing component (13) is inserted a head (21) of a pull-rod (14) which is held in the securing component (13). There is a tensioner (15) at the end of the pull-rod (14) opposite the head (21) which can be inserted into a part of the rim (8) of the additional wheel (2) and tightened. This device makes it possible to secure the additional wheel (2) on the wheel (1) in a simple manner so that the tractive forces are transmitted in the best possible way.
Dans un dispositif permettant de fixer de manière amovible une roue supplémentaire (2) sur la roue (1) d'un véhicule, au moins un élément de serrage (3) permet de serrer la roue supplémentaire (2) contre la roue (1) par l'intermédiaire d'une douille d'écartement (10). L'élément de serrage (3) comporte une pièce d'ancrage (13) qui est fixée sur la jante (4) de la roue (1) par une manivelle (6) et qui comporte un orifice (18) avec un trou traversant (20) présentant un rétrécissement (19). Dans l'orifice (18) de la pièce d'ancrage (13) est insérée la tête (21) d'un tirant (14) maintenu dans la pièce d'ancrage (13). A l'extrémité du tirant (14) opposée à la tête (21) se trouve un élément de tension (15) qui peut être inséré dans une partie de la jante (8) de la roue supplémentaire (2) et serré. Ce dispositif permet de fixer facilement la roue supplémentaire (2) sur la roue (1), de façon à transmettre de manière optimale les forces de traction.
