<p>A crawler vehicle (1) has a frame (2) extending along a longitudinal axis (3) of the vehicle (1), and two lateral track carriages (4) oscillating with respect to the frame (2) about a rear transverse axis (10). Each carriage (4) is connected to a front cross member (18) by a respective connecting assembly (25) having a pin (30), which permits relative oscillation of the cross member (18) and the carriage (4) about a hinge axis (17) perpendicular to the rear transverse axis (10), and has an eccentric portion (38) for varying the size of the cross member (18) between two given values as the carriages (4) oscillate about the rear transverse axis (10). <IMAGE></p> |
