23 Gears 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 9001:2000, 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.

26 Mobile Controls Mobile controls are control and safety systems for the travel and implement hydraulics in mobile machines. The range of products encompasses all the hydraulic function elements required for this purpose, such as displacement, pressure, flow and check functions and the associated components (mono blocks and sandwich blocks, built-in and builton elements). Integrated electronic sensors, controls and actuators round off the range. Mobile valves Central hydraulics Lift control Cylinder safety lock valve Stabilization valves Screw-in valves Flow dividers Flow, pressure, check valves Pilot control devices Ergonomic handle Various characteristic curves Low actuating forces Characteristics: Control blocks Brakes Steering units Open center (OC) Load sensing (LS) Load-independent flow distribution (LUDV) Flow up to 1600 L/min Nominal pressure up to 350/420 bar Medium and high pressure Mono-block and sandwich design Mechanical, hydraulic actuation and electrohydraulic actuation with or without OBE Hydraulic remotely powered braking systems Trailer brake valve Open center Closed center Reaction and non-reaction With or without speed control Priority valves

27 Mobile Electronics Rexroth offers a very wide range of electronic controllers for mobile machines. Collaboration with Bosch in the development, testing and production stages ensures that the electronic components are generally perfectly suited for immediate use in mobile machines. This guarantees reliability and a high degree of machine availability. The BODAS system is a flexible, scalable electronic system which can be used for all mobile machines. The consistent use of module architecture and the components which have been designed to work in perfect harmony with each other means that solutions can be created quickly and easily. This makes development much less expensive and quicker. The new BODAS software system offers an unequalled level of flexibility. Open software modules which complement each other allows the solution to be further developed easily and to suit one's individual needs as they grow and develop. This gives BODAS that all-important extra competitive edge. The BODAS tools allow the user to perform tasks related to software creation, simulation, evaluation and optimization of the current system himself.

28 Radial Piston Motors 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 highdisplacement 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.
