Abstract: A device for measuring a vehicle has at least one image capturing device, that includes at least one camera having at least one light incidence region configured to allow light from an object to be captured by the camera to strike the camera through the at least one light incidence region. The device also has a device for keeping the light incidence region clean and/or for cleaning the same, that features at least one deflecting element that is movable over the light incidence region in a way that allows it to prevent the deposition of dust and dirt on the light incidence region and/or to remove dust and/or dirt from the at least one light incidence region.

Abstract: An apparatus for measuring the running gear of a motor vehicle includes: a left measuring unit for positioning on a left side of the motor vehicle, in such a way that a measurement target on a left front wheel and a measurement target on a left rear wheel of the motor vehicle can be sensed from the left measuring unit; a right measuring unit for positioning on a right side of the vehicle, in such a way that a measurement target on a right front wheel and a measurement target on a right rear wheel of the motor vehicle can be sensed from the right measuring unit; and an evaluation device embodied to identify the vehicle geometry data from images of the measurement targets of the front wheels and of the measurement targets of the rear wheels by way of a comparison with reference images of the measurement targets.

Abstract: The invention relates to a method for calibrating a measurement system having at least one image recording apparatus (12) having at least two measurement cameras (31, 32) that form a stereo camera system, and having an analysis unit (13), wherein the measurement system is calibrated by means of a calibration device (22) having reference features (29).

Abstract: A method for calibrating a vehicle surroundings sensor (15) includes the steps of attaching at least one target pair (20, 22) to the rear wheels (12, 14) of a motor vehicle (7); recording the target pair (20, 22) using at least one measuring unit (32, 46) and determining the vehicle axis (64) from the recording; placing a target (16, 18) in a known position relative to a vehicle surroundings sensor adjustment or calibration element (62); fastening at least one measuring unit (32, 46) by means of fastening adapters (34, 48) to a running rail (4, 6); recording the target (18) placed on the vehicle surroundings sensor adjustment and determining the angular position of the vehicle surroundings sensor adjustment or calibration element (62) relative to the vehicle axis (64); aligning the vehicle surroundings sensor adjustment or calibration element (62) relative to the vehicle axis (64); and adjusting the vehicle surroundings sensor (15) relative to the vehicle axis (64).

Abstract: The tyre-changing machine includes: a bed for resting on the ground; a spindle extending from the bed and for mounting thereon a wheel having a rim and a tyre with a first flank and a second flank, the spindle configured to tighten the rim thereon so as to fix an imaginary axis of rotation of the wheel, with the first flank arranged in a distal position with respect to the bed and the second flank in a proximal position with respect to the bed; and a demounting tool having a non-rolling contact surface for contacting and pushing the second flank in a direction away from the bed until extracting the first flank from the rim, the spindle and the demounting tool being reciprocally movable along a direction substantially parallel to the axis with a stroke extending between two ends, to push the tyre out of the rim during the stroke.

Abstract: The tyre-changing machine (10) for fitting and removing vehicle wheels includes: a bed (12) for resting on the ground; a spindle (14) which extends from the bed (12) and on which is mountable a wheel (R) having a rim (C) and a tyre (PN) with two opposite flanks (F1, F2), the spindle (14) being configured to tighten the rim (C) on it and able to put in rotation the wheel (R) around an axis of rotation (A); and two bead breaking tools (32, 42) which are movable one towards the other in the proximity of the spindle (14) along a bead-breaking direction (Di) substantially parallel to the axis of rotation (A) of the spindle (14), the bead breaking tools (32, 42) having respective non-rolling contact surfaces (34, 44) able to contact and push in use the opposite flanks with the wheel (R) mounted on the spindle.

Abstract: A method and a device are provided for the optical axle alignment of wheels of a motor vehicle. At the wheels that are to be aligned, targets are mounted, having optically recordable marks, the targets being recordable by measuring units that have stereo camera devices. In a referencing process, using a referencing device that is integrated into the measuring units, a measuring position reference system is established for the measuring units. In a calibration process, in which a local 3D coordinate system is established using at least three marks of the target, the determination of a reference plane is carried out, using a significant mark of the target. Finally, using the reference plane, a vehicle longitudinal center plane is ascertained, while taking into account the measuring location reference system.
