ABSTRACT:
An axle measurement holder device to fasten a measuring head to the rim (5) of a vehicle wheel (2), includes a base body (3) for direct or indirect stable contact with a rim (5) of a vehicle wheel (2). Two arms (13, 14) arranged diametrically opposed feature respective hooks (15, 16) at their ends that are directed radially outward to hook into a tread of a tire (17). The ends of the arms (13, 14) directed radially toward the inside are attached by means of a pivot bearing (11, 12) to the end of a one armed lever (13, 14), the end of which is directed away from the base body (3), the other end of which is connected to the base body (3) via an articulation (20, 21) and tension springs (22, 23). The one armed levers (7, 8) can be tensed radially inward by means of clamping devices. The one armed levers (7, 8) are each preloaded radially toward the outside by centering springs (33, 34) which exert the same force and have the same characteristics and which are supported at a central point of the base body (3). The centering springs (33, 34) hold the arms (13, 14) and thereby the hooks (15, 16) located at their ends in any tensed position at the same radial distance to the axle that is defined by the axle shaft (6). This simplifies the attachment and clamping of the axle measurement holder device.
