Abstract: A crawler vehicle has a first track and a second track; a first drive wheel and a second drive wheel independent of each other and coupled to the first and to the second track respectively; a first electric motor and a second electric motor mechanically coupled to the first and to the second drive wheel respectively; an electric energy storage unit configured to deliver electric power; and an electric power transmission assembly, which is configured to transmit electric power from the energy storage unit to the first and to the second electric motor and comprises a first inverter electrically coupled to the first electric motor, and a second inverter electrically coupled to the second electric motor.

Abstract: A vibration damper for use particularly on wheeled vehicles. The damper has a cylinder formed to receive damping fluid and a working piston axially moveable therein, which piston is arranged on a piston rod formed with an axial passage and which divides the inner space of the cylinder into first and second working spaces. The vibration damper has a fluid communication axial passage for a fluid flow from the second working space to the first working space, and has a first adjustment device for adjusting the pressure stage damping and a second adjustment device for adjusting the traction stage damping. The first adjustment device has adjustable valve devices to change throughflow openings for the pressure stage, and the second adjustment device has a setting rod arranged in the axial passage of the piston rod for changing a first throughflow opening of a third valve device for the traction stage.
