Articulated vehicle
First Claim
1. Locking device for an articulation having two parts rotatably mounted upon each other around a longitudinal axis (x′
- x), wherein said locking device comprises two pieces integral in rotation, respectively, which each of said articulated parts, respectively a piece forming a collar (61) having an internal cylindrical face centered on said longitudinal articulation axis (x′
x) and a piece forming a bracket (64) extending transverse to articulation axis (x′
x) and having an end spaced from said axis (x′
x), and a pendulum type locking piece (62) suspended to said spaced end of bracket (64) and mounted oscillating around an axle (63) parallel to articulation axis (x′
x) and located in a plane (P2) passing by a said axis (x′
x), said pendulum locking piece (62) having a lower end (66) spaced from internal face of collar (61) by a narrow clearance and resting 15 on said internal face in case of inclination of plane (P2) in which is located the suspension axle (63) in relation to the apparent vertical direction that is to say the resultant of gravitational and centrifugal forces, causing buttressing of said pendulum piece (62) on collar (61) and locking of the articulation.

Abstract
An articulated vehicle includes a rear frame and a front frame linked by an articulation associated with the device for removably locking controlled by a pendular member mounted oscillating on the front frame between a median position for unlocking the articulation and a spaced apart position for locking the articulation, at least when the vehicle is stopped. The vehicle comprises elements for controlling the unlocking of the articulation, at least during start-up, including an auxiliary platform integral in rotation with the rear frame and comprising, at least, two footrests arranged at substantially the same level relative to the ground, on either side of the articulation axis and constituting each, on the side towards which the front frame is inclined, a support for the front frame to be set upright by the vehicle driver, the pendular member returning to its median position for unlocking the articulation.
