Abstract: What is shown and described is a clamping device (1) with hub centering for attachment of an automobile wheel to the shaft of a balancing machine, with a contact flange (2) with several centering elements (3) guided in a radially moveable manner on the contact flange (2) for centering engagement in a centering hole of the rim, and with a clamping sleeve (4) guided in a moveable manner axially to the contact flange (2), wherein the clamping sleeve (4) and the centering elements (3) are kinematically coupled such that an axial movement of the clamping sleeve (4) leads to a radial movement of the centering elements (3). According to the invention, a provision is made that at least one tension lever (16) connected in an articulated manner to the clamping sleeve (4) and a centering element (3) is provided for the kinematic coupling of clamping sleeve (4) and centering element (3).

Abstract: A quick adjusting nut (1) made especially for attaching a vehicle wheel to the mounting shaft of a balancing machine, with a housing part (2) and with at least two radially movable thread segments (3) arranged in the housing part (2) and with an actuator (4) for radial movement of the thread segments (3), each thread segment (3) having an inside thread section (3a) and the thread segments (3) being radially movable along guide surfaces (7) of the housing part (2) from an engagement position outward into a disengagement position. The guide surfaces (7) for the thread segments (3) slant upward in the radial outward direction and interact with complementary slanted guide surfaces of the thread segments (3) during movement in the radial direction.

Abstract: A method for measuring and testing a vehicle frame (15), in particular a commercial vehicle or bus frame, wherein a radiation source and a radiation receiver are arranged in front of the frame (15) and radiation is beamed from the radiation source toward the frame (15) and onto a reflector support (1) having at least one reflector (2, 3, 4, 5). The reflector (2, 3, 4, 5) is assigned to a part of the frame (15), and the radiation is reflected by the reflector (2, 3, 4, 5) to the radiation receiver and a measuring device determines location coordinates of the reflector (2, 3, 4, 5) at different measuring points of the frame part. A substantially non-deformed section (A) of the frame part is ascertained from the resulting measuring points (P) and the variation of the measuring points (P) from the non-deformed section (A) is determined.

Abstract: A clamping device for mounting a vehicle wheel on a balancing machine. The clamping device has a clamping flange and a plurality of centering bolts. The clamping flange is provided with plural sets of recesses for the centering bolts. An insertable section of each centering bolt is removably insertable into a recess. A profiled contour in the insertable section of the centering bolt and an inner contour of a sidewall of the clamping flange delimiting the recess are not circular and have complementary shapes such that the centering bolt is accommodated in the recess such that some sections of the centering bolt can be rotated about the longitudinal axis thereof. When the centering bolt is rotated, at least one subarea of a circumferential surface in the insertable section of the centering bolt frictionally engages with at least one adjacent subarea of the sidewall of the clamping flange delimiting the recess.

Abstract: A clamping flange that is designed to press a rim of a vehicle wheel against a flange of a shaft of a balancing machine and has a clamping plate with a plurality of recesses for accommodating centering bolts and a central opening to be slid onto the shaft of the balancing machine. The centering bolts can be inserted into the front of the clamping plate. The clamping flange is slidable onto the shaft while a clamping arrangement is provided for centering the clamping flange on the shaft. The clamping arrangement encompasses a clamping sleeve which is mounted in the central opening so as to be movable in an axial direction relative to the clamping plate. The clamping sleeve is movble into a clamping position by applying a pressure acting in an axial direction. In the clamping position, the clamping sleeve is mounted without play on the shaft and clamping flange.
