This enables simple application in that the ring element can be applied to the shaft journal manually, ie. with such a small force that no tool or complicated application procedure is required.
    Furthermore, it is possible to obtain a robust holding and locking around the shaft journal both axially and circumferentially by clamping force. This further makes it possible to use lightweight materials such as aluminum, when no pressing force is required for applying the device.
    According to an embodiment of the sensor holder device, said ring element has at least a first and a second end and wherein said clamping arrangement comprises holding means for adjustably holding said ends together. This makes it possible to obtain a robust holding by adjusting the clamping force and to remove the holding device if necessary. Furthermore, readjustment is possible, for example if the holding device has not ended up in the correct position during assembly, which ensures quality.
    According to a ring element of an embodiment of the sensor pouring device, said only ring element part is constituted. As a result, the sensor pouring device consists of a few articles, which means that eating clamping is only required in one place.
    According to an embodiment of the sensor pouring device, said ring element comprises two separate ring element parts. As a result, the ring element does not need to be axially applied but can be applied directly at the position along the shaft pin at which the sensor pouring device is to be positioned, which consequently can be achieved with the hub device arranged on the shaft pin.
    According to an embodiment of the sensor pouring device, said clamping arrangement comprises a screw connection. This enables efficient eating and easy removal by screwing on.
    According to an embodiment of the sensor pouring device, said clamping arrangement comprises alternative fixing possibilities depending on whether said axle pin refers to the right or left side of the vehicle. This makes it possible to use the same holding devices on the right and left side without complicating the assembly, which reduces the manufacturing cost and streamlines the assembly time. Said alternative fixing possibilities consist according to a variant of parallel holes for screw joints, where one hole is intended for insertion of screw joints in one direction and the other parallel hole is intended for insertion of screw joints in the opposite direction, so that regardless of whether the holding device is to be mounted on the right or left side, the screw connection can be inserted from above. According to an embodiment of the sensor holder device, said ends are designed to mutually form an axial sealing configuration. This prevents dirt from the vehicle's wheels from passing through to the vehicle's hub device.
    According to an embodiment of the sensor pouring device, said sealing configuration comprises a mold locking function. In this way a more robust locking of the sensor pouring device is obtained at the same time as dirt is prevented from passing through to the hub device.
    According to an embodiment of the sensor pouring device, at least said ring element is made of a lightweight material, preferably aluminum. As a result, the device takes up less weight. Furthermore, more cost-effective construction is possible as machining of aluminum is simpler than cast iron or equivalent.
