The connecting bar comprises a central portion (21) which slidably engages with a supporting frame (3), and two lateral portion (23) respectively connected to the central portion and respective lateral member in rotary manner. The two lateral members are rotatably engaged with vehicle wheels and rotatably connected to the supporting frame to oscillate about respective rotation axes (9). A power transmission is interposed between the wheels and a power input shaft. The steering assembly controls the angular position of the lateral members about the rotation axes, and comprises a steering actuating cylinder (16) acting on one of the lateral members. |
