Axial piston units are available in 

the form of pumps and motors in 

bent axis design or swashplate design 

for medium and high pressure 

ranges. They are the main components 

in the hydrostatic transmission. 

Compact size and high 

power density, economy and reliability 

are characteristic advantages 

promoting the use of hydrostatic 

transmissions, together with the 

fact that they meet the demand for 

high speed and high torque, as well 

as optimum efficiency. 

Characteristics: 

U Open and/or closed circuit 

U Displacement volume 

5 to 1000 cm 3 

U Nominal pressure up to 

450 bar 

U Maximum speed up to 

11,000 rpm 

U Maximum power output 

933 kW 

Our versatile transmissions for 

mobile applications can be combined 

in a variety of ways with 

pumps, motors and open or closed 

loop control devices to offer the 

optimum design for every drive 

application and every power range. 

Special advantages: 

U Infinitely variable speed setting 

at constant or variable input 

speed 

U Direct, jerk-free change of 

direction of rotation 

U Easy, ergonomically favourable 

operation 

U High turnaround 

U Automatic torque conversion 

Axial piston pumps and motors 

are used for the propel drive and 

implement hydraulics in a wide 

variety of mobile machines.

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.

Hydrostatic Steering Units LAG 

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, ...

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, 

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.

The mobile electronics sector 

supplies components meeting all 

the requirements for use in mobile 

machines. Their great reliability 

when subjected to rough mechanical 

handling, in extreme summer 

and winter conditions, and in the 

presence of electromagnetic and 

electrostatic interference has been 

demonstrated in tests and proved 

in everyday use. 

The programmability of components 

for mobile electronics makes 

it possible to realize intelligent new 

solutions in addition to standard 

functions and to incorporate the 

electronic control units into other 

machine systems through this communication. 

Product range for mobile electronics 

With programmable control units, 

sensors, input devices and other 

components, the mobile electronics 

range from Rexroth includes all 

the parts needed for a complete 

hydraulic drive system from a 

single source. Complete solutions 

combining travel functions and 

working functions are optimally 

matched with one another. 

Tried-and-tested tools are available 

as handheld units and as PC applications 

for simple parameterization 

in everyday use and effective 

troubleshooting when service is 

required. 

For more ambitious users of 

mobile electronics, the BODAS 

programming system is a convenient 

means of developing software 

to standard IEC 61131-3. 

In addition to the components 

presented here, mobile electronics 

is also available as “integrated 

electronics and sensor systems” 

in hydraulic components. This 

version yields further advantages, 

such as the elimination of wiring, 

minimization of the installation 

space and preliminary testing of 

the subsystem. The “integrated 

electronics” is described with the

Parameterization and Programming Tools 

Parameterization with BB-3 or 

BODEM 

The application software for control 

units is parameterized when 

developing and optimizing prototypes, 

as well as when commissioning 

standard vehicles and machines. 

The parameterization tools are 

used, for example, to set ramp values 

for acceleration and deceleration, 

as well as other applicationbased 

values. Actual process values 

can also be monitored and recorded 

with the tools (but only with the 

PC software BODEM) and error 

messages output in plain text.

used for convenient and reliable 

programming of the universal control 

units. Programs are compiled 

on the PC using programming 

languages to standard IEC 6 1131-3 

and additional support, such as 

debugging and simulation. Upon 

completion of the program development, 

the program code can be

Interfaces for Mobile Electronics 

U Pumps, motors and valves 

with proportional or switched 

electrohydraulic control can be 

controlled directly from the 

outputs of the mobile electronic 

units 

U Integrated electronic units in 

hydraulic components are 

preferably controlled via the 

CAN bus or analog voltages 

U Such input devices as joysticks 

and foot pedals deliver setpoints 

in the form of input 

signals which are processed 

by control units, amplifiers or 

integrated electronic units. 

Hydraulics 

Electronics 

Here too, major advantages are 

obtained by using the CAN bus 

instead of analog voltages, such 

as the reduced wiring effort 

and extended diagnostic capabilities 

U Other input signals for control 

units or amplifiers are delivered 

by a whole variety of sensors. 

Signal transmission with 

analog voltages or currents 

frequently yields the advantage 

of unlimited speed for real-time 

control functions, although 

the CAN bus can also be used 

occasionally
