<p>The vehicle has a mechanical locking device with a mechanical interface and a vertical locking cylinder such that hydraulic pressure in the cylinder opposes force of a spring, and a pivoting lower plate pivots, when the vehicle is in work mode. The cylinder is not supplied with hydraulic power, and a piston head traverses a housing of a fixed upper plate and is locked in a conical housing of the lower plate if front wheels and rear wheels (204) are aligned, so as to lock a rear axle (203) when the vehicle is in road mode. A spring suspension system (201) is connected with the axle.</p> |
