Abstract
Abstract This invention relates to inspection or X-ray testing system for vehicle wheels consisting of a rim and a supporting structure of the kind comprising an X-ray tube, and X-ray screen with a post-positioned monitor and a system for reception of the wheel fed in rim-down, for placing the same into the beam path of the X-ray tube, and for ejecting the wheel after inspection. To shorten the inspection or testing period, the system according to the invention comprises a chute displaceable around a horizontal pivot spindle for the wheel which may be pivoted to the appropriate positions for reception, immobilization during the testing or inspection and the ejection of the wheel. The pivot spindle extends parallel to the X-ray screen as well as to the chute. The chute has a stop system to establish the testing position of the wheel on the chute and a clamping mechanism for immobilizing the wheel slid into the testing position. The X-ray tube is movable at least between a first operating position for the transillumination of the axial rim halves, and a second operating position for the transillumination of the wheel element support structure.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
244 words
In a system for X-ray inspection of a motor vehicle wheel comprising a rim and an inner support structure, of the kind comprising an X-ray tube situated in a radiation-proof casing and a stationary X-ray screen with a post-positioned monitor, for totally transilluminating the wheel element held by sections in the beam path of the X-ray tube, the axial rim halves and the inner support structure being transilluminated in the corresponding testing or inspection position by rotation of the wheel, and a system for reception of the wheel which is fed in rim-down, for placing said wheel in the beam path as well as discharging the wheel after inspection, the invention which consists in that the system comprises a chute which is displaceable around a horizontal pivot spindle and intended for the wheel, said chute being pivotally displaceable into the positions in question for reception, immobilisation during inspection and discharge of the wheel, and wherein said pivot spindle of said chute extends parallel to said X-ray screen as well as to the working surface of said chute, said chute having a stop system for location of the inspection position of the wheel on said chute and a clamping mechanism for immobilising the wheel slipped into the inspection position, and wherein said X-ray tube is displaceable at least between a first operating position for transillumination of said axial rim halves and a second operating position for transillumination of said inner support structure of the wheel.
Claim 2
Dependent Claim
244 words
In a system for X-ray inspection of a motor vehicle wheel comprising a rim and an inner support structure, of the kind comprising an X-ray tube situated in a radiation-proof casing and a stationary X-ray screen with a post-positioned monitor, for totally transilluminating the wheel element held by sections in the beam path of the X-ray tube, the axial rim halves and the inner support structure being transilluminated in the corresponding testing or inspection position by rotation of the wheel, and a system for reception of the wheel which is fed in rim-down, for placing said wheel in the beam path as well as discharging the wheel after inspection, the invention which consists in that the system comprises a chute which is displaceable around a horizontal pivot spindle and intended for the wheel, said chute being pivotally displaceable into the positions in question for reception, immobilisation during inspection and discharge of the wheel, and wherein said pivot spindle of said chute extends parallel to said X-ray screen as well as to the working surface of said chute, said chute having a stop system for location of the inspection position of the wheel on said chute and a clamping mechanism for immobilising the wheel slipped into the inspection position, and wherein said X-ray tube is displaceable at least between a first operating position for transillumination of said axial rim halves and a second operating position for transillumination of said inner support structure of the wheel.
Claim 3
Dependent Claim
57 words
A system according to claim 1, wherein said pivot spindle of said chute passes at right angles through the beam path of said X-ray tube, and extends below the feed plane and above the discharge plane for the wheel as well as close to a line passing at right angles through the centre of said X-ray screen.
Claim 4
Dependent Claim
31 words
A system according to claim 2, wherein said pivot spindle is located laterally of said line at right angles, which faces away from the feed and discharge portion of said chute.
Claim 5
Dependent Claim
39 words
A system according to claim 1, wherein said X-ray tube is pivotally displaceable in a vertical plane coinciding with said right-angle line and extending at right angles to said pivot spindle of said chute for assuming its operating positions.
Claim 6
Dependent Claim
31 words
A system according to claim 4, wherein a pivot spindle for said X-ray tube extends within the X-ray screen plane and through said line at right angles to said X-ray screen.
Claim 7
Dependent Claim
75 words
A system according to claim 4, wherein said stop system comprises two mutually opposed rollers arranged symmetrically with respect to the pivoting plane of said X-ray tube, each said roller having allocated to it a wheel guide extending in the direction of the feed and discharge portion of said chute, both wheel guides extending divergently with respect to each other in the direction towards said discharge portion and at least one said roller being rotatable.
Claim 8
Dependent Claim
23 words
A system according to claim 1, wherein a traction mechanism drive effective in two directions is incorporated for pivotal displacement of said chute.
Claim 9
Dependent Claim
35 words
A system according to claim 1, wherein a coupling linkage is incorporated for pivotal displacement of said X-ray tube, said coupling linkage being arranged to the pivotal displacement of said chute to said X-ray tube.
Claim 10
Dependent Claim
31 words
A system according to claim 1, wherein said chute comprises a flat plate which is provided with a rearwardly open excision for free passage of the beam of said X-ray tube.
Claim 11
Dependent Claim
30 words
A system according to claim 4, wherein said X-ray tube is movable complementarily in translatory displacement at right angles to said pivot spindle of said chute within its pivoting plane.
Claim 12
Dependent Claim
34 words
A system according to claim 4, wherein said X-ray tube is pivotally displaceable with respect to its first pivoting plane in another plane which extends at right angles and vertically to said first plane.
