37 37 Radial Piston Motors 3 MCR radial piston motors are low-speed hydraulic motors based on the multi-stroke principle. The relationship between roll diameter and cam profile is optimized inside the central rotary group, thus ensuring the best possible balance of forces between piston and cam path, as well as extending the service life. The step-piston rotary group or high-displacement rotary group yields a very compact drive unit with high power density. MCR motors can be used for operation in both open and closed circuits.

66 66 Mobile Controls Hydrostatic Steering Units LAG 4 Steering unit LAG U The steering unit LAG is used in the hydraulic steering circuits of motor vehicles and mobile machines with high axle loads and driving speeds of up to 50 km/h. U Even heavy vehicles can be steered without difficulty with the aid of a steering unit. The absence of a mechanical connection between steering unit and steered axle makes it possible to realize designs which would be impossible with conventional steering systems. U The steering unit contains all the necessary valves for safeguarding the steering unit and cylinder in the hydraulic steering circuit, thus eliminating the need for additional piping. U Vehicles with LAG steering unit can also be steered manually if the hydraulic pump fails, as the steering unit then serves as manual pump to the steering cylinder. LAGC The delivery volume in servo mode (supplied by the hydraulic pump) and in emergency mode (supply failure) is the same in the LAGC unit. LAGU and LAGZ The force required on the steering wheel is reduced through the change in transmission ratio when the LAGU and LAGZ units are installed. In many cases, this is the essential prerequisite for compliance with permissible ceilings. A second steering pump is often unnecessary. The steering unit LAGU operates according to the principle of 2:1 chamber isolation. The delivery volume is halved in emergency operation. The installed dimensions are identical with those of the LAGC unit for the same sizes. The steering unit LAGZ operates with two rotor sets in servo operation. One rotor set is deactivated in emergency operation, thus reducing the delivery volume. The manual force is reduced proportionally with the delivery volume. Rotor sets can be combined as desired within the individual series, thus permitting transmission ratios of 2:1, 3:1, 4:1,...

69 69 Gears 5 Planetary gears are exceedingly compact and therefore eminently suitable for installation in frequently confined spaces, such as in mobile machines. Depending on the required transmission ratio, they have two, three or more planetary stages, sometimes also in combination with spur gear or bevel gear stages. Modified gears are also available for specific drive systems, especially for high torques, in addition to the large range of standard gears. Top-quality gearing and high-grade materials make these gears reliable drive components. This is additionally ensured by a quality management system to DIN ISO 9001, modern machine tools and up-todate assembly and test technology. The gearboxes are designed for mounting on or in hydraulic motors and are normally supplied together with the latter. Others can be driven by electric motors or have free shaft ends for mounting such connecting elements as couplings or belt pulleys. Continuous monitoring of the market and technological developments in engineering design and manufacturing yield gearboxes produced to state-of-the-art standards.
