Articulated vehicle, such as an extra-long railway car intended for transporting automobiles

An articulated vehicle (1) for railway transport of automobiles comprising two half-frames (2, 3) adapted to be supported at one of their ends with their own rolling devices and at their other facing ends on an underframe (4) common with the two half-frames (2, 3) and having rolling devices (5, 6),

• said two half-frames (2, 3) being connected to one another by a spherical roller bearing (7) and connected in rotation with the underframe (4), each about one of two front and rear pivots (8, 9) carried by the underframe (4) in a plane along the longitudinal axis of the underframe and equidistant, on the half-frames, from the spherical roller bearing (7) and, on the underframe (4), from a median transverse plane of this underframe (4), said pivots (8, 9) including elastic means (10, 11) for absorbing the deflection of an arc (12, 13) on which the half-frames (3, 3) can pivot with respect to the underframe (4), said underframe (4) having spaced first and second lateral transom supports including shafts (14 and 15 or 16 and 17) disposed at each of the facing ends of the half-frame such that the load on each of the facing ends is borne by said first and second lateral transom supports of said underframe,
• said vehicle being characterized in that there are included first and second planes (P.sub.1 P.sub.2) transverse to the longitudinal axis of the underframe and each including the shafts of first and second lateral transom supports, said first and second planes being distinct from third and fourth planes (P.sub.3, P.sub.4) transverse to the longitudinal axis of the underframe and each third and fourth plane including a shaft forming the two pivots (8, 9).
