Liebherr-Transportation Systems has designed a new family of highly integrated electro-hydraulic actuators for rail cars. The actuators significantly improve ride comfort and reduce wear on both wheels and tracks. They are very compact and can be fully integrated into the bogie. The actuator is simply slid sideways into the opening, which ensures optimal accessibility after installation. The electronic control board or individual hydraulic elements can therefore be exchanged within a short time and without the actuator itself being removed. Another advantage of these devices is their maintenance-friendly design. All components which could potentially fail can be replaced quickly and easily. The parts subject to wear were reduced to small assembly modules. To keep maintenance and overhaul costs at a minimum, the new actuators are not coated.
