Apparatus for geometric measurement, particularly for a vehicle with steered wheels or wheels that are only slightly steered or are not steered, of the type comprising two first measuring casings and two second measuring casings from each of which second casings extends a longitudinal arm carrying at its end an angular measuring device. The two first casings (6, 7) are fixed on the steered wheels (2, 3) and the two second casings (8, 10, 12; 9, 11, 13) are secured on the unsteered or only slightly steered wheels (4, 5), so as to avoid any substantial deviation of the arms (10, 11) during geometric measurement of the vehicle. The first casings (6, 7) are each substantially internal to an imaginary geometrical cylinder (C.sub.6 or C.sub.7) with an axis (A.sub.6 or A.sub.7) corresponding to the axis of rotation of the steered wheel (2 or 3) and of a diameter corresponding to the diameter of the rim of the wheel (2, 3). The second casings (8, 9) each have an arm (10, 11) which passes through while extending longitudinally of an imaginary geometrical cylinder (C.sub.8 or C.sub.9) having an axis (A.sub.8 or A.sub.9) corresponding to the axis of rotation of the unsteered or only slightly steered wheel (4 or 5) and of a diameter corresponding to the diameter of the rim of the unsteered or only slightly steered wheel (4 or 5).
Apparatus for geometric measurement for a vehicle having a longitudinal axis, a steering wheel, steered wheels and wheels that are only slightly steered or are not steered, comprising two first measuring casings and two second measuring casings, an arm substantially parallel to said longitudinal axis, extending from each of said second measuring casings, each arm carrying at its end angular measuring means;
Apparatus for geometric measurement for a vehicle having a longitudinal axis, a steering wheel, steered wheels and wheels that are only slightly steered or are not steered, comprising two first measuring casings and two second measuring casings, and an arm substantially parallel to said longitudinal axis extending from each of said second measuring casings, each arm carrying at its end angular measuring means, each of said two first measuring casings not having any arm extending therefrom, said two first measuring casings, being fixed on the steered wheels and said two second measuring casings being secured on the unsteered or only slightly steered wheels, so as to limit deviation of the arms during geometric measurement of the vehicle, and wherein paths of action or of emission and of reception or of communication between facing casings comprised of a first measuring casing and a second measuring casing on one side of the vehicle, and between the angular measuring means are substantially invariable in the course of geometric measurement of the vehicle.
