Together we movethe earth

Heavy-duty transmissions, precisionaxles and intelligent electronic sys-tems are the components that givea superior driveline package -- rightat the heart of every constructionmachine. Apart from the basic orientation tovarious types of construction ma-chine, ZF driveline components arematched more precisely to the rele-vant vehicle requirements in co-operation with the manufacturers.The modular system structureallows lots of ways of achieving thebest driveline design through co-ordinated development. Interfaces

Modern construction machines perform a large variety of complex jobs.

ZF transmission and axle systems are designed for specific application

conditions. These driveline components stand for the ultimate in per-

formance, economy and comfort. Reliability and easy operation provide

maximum efficiency.

At the sametime, attention is always paid to the requirements of the fleet operator and driver, both in their workwith the machine as well as with upkeep and main-tenance.ZF is setting international benchmarks in the designof vehicle components. ZF manufactures transmis-sions, steering systems, axles, chassis componentsand complete systems for cars, commercial vehiclesand off-road machinery.Concentration of expertise within the ZF group generates extensive synergies. Basic research, state-of-the-art tools for simultaneous engineering as wellas materials and surface technology are essentialelements of the ZF know-how pool.An innovative spirit, quality consciousness andsmooth co-operation with vehicle manufacturerscome together to make ZF a valuable and depen-dable system partner who will help you share theload.


ZF -- The Specialist forDriveline Technology

ZF transmissions for construction machinesoffer the market completely new standards. In particular the quiet running and low peaksof stress enormously increase both the ser-vice life as well as the reliability. Consequent-ly, construction machines offer more workingcomfort and better economic efficiency. Withthe modular construction and cost-optimizeddesign operating costs are kept as low as pos-sible. Helical gears with high tooth contactreduce the noise level. Extremely shortshafts reduce deflection and tooth contactfaults. The vertical arrangement of the spurgear ratios bridges the height differencebetween the input and output shafts.Consequently, the axle differential can beintegrated into the housing. An additionaltransfer box is then unnecessary.

Based on decades of experience in the field of driveline technology for

construction machines, ZF has developed into a pre-eminent specialist

in transmissions and axles for construction machines. Not least due to

the in-house development capability, continuous product inspection and

modern production techniques, ZF products always reflect the latest

state of technology.

ZF axle systems form a solid basis for any vehicledesign. Through consistent systemization, steeringaxles in the series ZF-Multisteer and the poweredrigid axles of the ZF-Multitrac series can be inte-grated like a modular kit into almost all vehicleand application profiles -- both an economical andperformance-optimized solution. Slim axle hous-ings, small axle center drives and high ratios in thewheel heads are the essential parts of these inno-vative axle ranges.The Multisteer axle systems were designed forextreme stresses. The steering cylinder is protectedin the axle housing. Combined with the negativescrub radius, this allows high maneuverabilityeven with large front wheels. Multitrac axles areequipped with integrated wet multi-disc brakes.They ensure a high braking torque, need only lowmaintenance and are self-adjusting.

ZF driveline technology: vehicles and performance classes for wheel loaders

Wheel loaders are amongst the most purchased andtechnically most demanding off-road vehicles. Theyhave to be quick and extremely maneuverable bothforwards and backwards and also be able to con-centrate powerful forces on the bucket for breakingand digging. Apart from high power, sensitive con-trol is also a special requirement. Here, exact shunt-ing is essential, along with easy shifting and a fastchange of direction when reversing. Anyone watch-ing a well-practiced driver operating his wheelloader can appreciate the significance of intelligenthigh performance driveline technology in the dailyroutine -- in terms of both efficiency and safety.

Power packed into the smallest space

Due to their compact dimensions, “mini wheel load-ers” excel with high maneuverability even in tightspaces. So they are not just a perfect complement to larger construction machines, but rather withtheir wide range of attachments they are also ideallysuited to the most varied fields of application: inlandscaping, recycling, in agriculture or as materialand equipment carriers in the wider constructionindustry.The reduced space available in compact loadersdemands a compact but rugged design of the trans-mission and axles. The transmission must reliablyreact to quick gear-shifting and changes of direction,whereas the axles should ensure precise vehiclesteering.

ZF Driveline Systems for Compact Loaders

Optimized for size, but stillpowerful -- the driveline con-cept for compact loadersallows no compromises. Thehydrostatic transmission ismounted directly on the rearaxle.

Compact loaders are employed where

the large machine has no access or

is overdimensioned. Apart from the

amount of load, the requirements on

the vehicle are however similar.

Optimized power play

To be able to satisfy these requirements in routineuse, maximum ground contact, uniform distributionof the drive power to all wheels and uniform loaddistribution are important for a high level of safety.Apart from these viewpoints for reduced cycle timesand more operator comfort, economic efficiencyand service life should not be forgotten.The stresses which come into play demand thehighest level of ruggedness and reliability from allcomponents in the transmission chain.

Power and precision combined

The wheel drive enables a rapid change of positionwithout disturbing the substrate. Easy tool changingmakes the mobile excavator into a multifunctionworking machine which however needs to be movedprecisely. Along with the skill of the excavator opera-tor, well-conceived mechanical driveline technologyis required to provide smooth movements whenswiveling and braking. With the ZF driveline tech-nology high power transmission and millimeter posi-tioning are perfectly combined. Depending on theapplication, the axles are in this respect stressed dif-ferently. In tight construction sites a precise responseof the steering axle should also support accuratepositioning.

ZF Driveline Systems for Mobile Excavators

The newly developed range ofaxles and transmissions, preciselymatched to one another, under-lines ZF’s system capabilities inmobile excavator applications.

Quickly moving from site to site,

versatile tools for the boom -- mobile

excavators are characterized by high

versatility in job scheduling. In this

respect, both power and precision

are demanded.

More mobility and maneuverability

Backhoe loaders are a combination of wheel exca-vators and wheel loaders: loading at the front, dig-ging at the back -- and in between a power drive,embedded in a maneuverable vehicle design.As genuine all rounders they can also be combinedwith various hydraulic attachments, for example fordrilling, digging, pumping, breaking, compacting orcutting. Consequently, backhoe loaders are seenwhere the most varied work has to be done and spe-cial machines would not be economical. In particular a lot is demanded from the front axle.It has to overcome the conflict between high load-ability and high steering precision. The universalaxle concept facilitates front-wheel and four-wheelsteering.

ZF Driveline Systems for Backhoe Loaders

The system for backhoe loadersconsists of a steerable front axle,the compact, powered rear axleand a synchronized four-gear orpowershift transmission.

The demands on compact, self-pro-

pelled off-road vehicles are continu-

ally increasing. This is particularly

true in inner-city areas were modern

vehicles must in future be more

mobile and maneuverable. This trend

is also expected to continue with

backhoe loaders.

The telescopic handler can be quickly fitted withshovel, fork, grab, working platform and other toolattachments for the most varied jobs. This meansversatility in application in a wide variety of fields,from the construction site through to agriculture.The ZF driveline versions for telescopic handlers arealso versatile. Depending on the type, low-boom orhigh-boom designs are possible. Special telescopichandler axles support the 4-wheel steering system.

ZF Driveline Systems for Telescopic Handlers

The axle series was speciallydesigned for telescopic handlers.The WG 92/98 transmissions arerated for fast reversing andspeedy travel between jobs.

Versatility and maneuverability are the

strengths of the telescopic handler.

This flexibility is due to intelligent

Compressed power

Compactors are found in road building and on largeconstruction sites. For the best compacting resultsthe maximum transfer of power to the substrate isjust as important as a stepless change of the drivingspeed. For use on uneven terrain optimum weightdistribution is also essential for increasing the trac-tive effort.The ZF compactor axle profits from the applicationof well-proven components from other axle ranges,particularly with regard to service life and flexibili-ty. Very good mounting methods can be realizeddue to the compact modular design. For example,various hydraulic motor connections for directmounting, the mounting of a transfer box and also a number of different differential systems are pos-sible. The internal stored-spring brakes are releasedby the hydraulic operating pressure.

ZF Axle Systems for Compactors

ZF has developed extremelyrugged and powerful rear axlesfor single drum compactors.

Single drum compactors are com-

pacting machines with a front facing

drum and treaded wheels on the rear

axle. They are designed for applica-

tions demanding high tractive and

grade performance.

Sensitivity and pulling power

Graders must adapt to the most varied ground con-ditions quickly and impressively. Optimum weightdistribution for achieving maximum tractive effortis one of the primary requirements. To master diffi-cult conditions in the working routine, smoothmovements in conjunction with a high pullingpower are decisive for excellent working perfor-mance and for overcoming high material resistan-ces. This system is supported by an operationalhydraulic system which, with precise and sensitivemovements, contributes to exact, fine leveling.

ZF Driveline Systems for Graders

ZF driveline systems for gradersare a combination of front andrear axles from the APG rangeand transmissions from the WGrange.

Irrespective of whether rough-work-

ing in creating site roads or under

laser control for the fine leveling of

large areas, the grader is the special-

ist for a level substrate.

A powerful mixture

Fleet operators and superstructure manufacturersare placing increasing requirements on the drive to the mixing drum. Higher power and harder dutycycles are only one aspect here. With two series ZFhas established a remarkable capability in mixerdrivelines.The PLM range, with its slow running hydraulicmotor integrated into the transmission and a follow-ing planetary drive stage, is a compact unit with apowerful drive. The driveline of the P/PK rangeconsists of a two-stage planetary drive which isdriven by an external hydraulic motor. Both rangesoffer economical and well-proven technology alongwith low-maintenance and low-wear operation alsounder high stress conditions.
