Always onthe safe sideZF Test Systems for tires

2ZF test systemsfor tiresThe requirements placed on today’s tires are becomingincreasingly diverse. They should be safe and reliable,generate little noise, offer good comfort, producehardly any abrasion and thus be sustainable.Velocity and load tests, tests of noise level and comfortcharacteristics, tread wear tests or measurements ofresponse behavior under different operating conditionsare just a few examples of how ZF Test Systems cansupport tire manufacturers with various test rigs.R&D and production test benches made by ZF offer allkinds of test procedures to ensure a fast developmentand a certified quality assurance.Tires and wheels are the most delicate and mostseverely stressed parts of a vehicle. Great importance istherefore attached to safety and quality. Only consistenttesting guarantees that nothing is left to chance anddrivers remain safely on the track.Types of test rigs:Characteristic, low speed uniformitybalancing, high speed uniformity, high speed/ endurance, tire noise, rolling resistance, tiretread wear, spring rate, fully automized testlines, customized solutionsWe test:Uniformity, runout, rolling resistance, dynamicand static characteristics, tire noise, staticspring rate, dynamic spring rate, temperature behavior, endurance, according yourrequirements

3Rolling resistance tester for car tiresThe machine measures torque (power), forceand deceleration. It offers SAE and ISO testson reference level with highest precision anda cross talk free sensor hub.Tire characteristics:From low to highforcesModern tires must compete in a field of extremes: Goodwet grip but creating low rolling resistance forces. Perfecthandling behavior but they must show low wear andgood tread abilities. ZF Test Systems help tire manufacturer and car makers to verify related conditions andtire values with highest precision and reproducibility.ZF Test Systems rolling resistance machines are used inEuropean reference laboratories and have become wellknown for its hydrostatic wheel hub. The new force andmoment tester can put dynamic drive file verificationfrom the track into the laboratory which saves costs andavoids taking risk of driving on race tracks.Force and momenttesterIt is highly dynamicon all axles andallows a very fastpositioning at highprecision. It offersdrive file simulation.

4High speeduniformity machineOffers a very widemeasuring frequencyrange due to the highest natural machinefrequency of 580 Hz.The uniformity measuring speed reachesup to 360 km/h.Uniformity:From low to high speedZF offers for customer laboratories two very precisemachines: The ZF low speed uniformity and the ZF highspeed uniformity machine. The HSU types allow measuring high speed uniformity values up to 360 km/h withhigh resolution and with lowest influences from machineresonances which guarantees highest precision andbest reproducibility of measuring results. The low speeduniformity machine offers more than just side wall failuredetection and uniformity test with or without rim. Theinnovative automation system ZF Modas provides tailormade data handling and reliable and useful automationof ZF’s test systems.Laboratory lowspeed uniformitymachineTests on tire and tire/wheel assembly.Uniformity and runout are based on theusual standard uniformity procedure.

5Endurance testerRobust and reliable ZF endurance testers arein operation for passenger car tires as well asfor truck tires. They provide highest availabilitypaired with precise and wearless mechaniccomponents.Basics:Durability and wearTread wear and endurance testers are basic test machinesfor tire manufacturers. ZF offers those machines for sizesof modern passenger car tires as well as for truck tires asstandard solutions. Last but not least: Even bigger tires –for example from construction equipment – fit on ZF testsystems. Tires can be mounted easily, and the machinesoffer good access to the testing position.Furthermore, the new ZF Tread Wear Tester for passengercar as well as truck and bus tires is capable to simulatereal vehicle tests in a lab environment by drive file operation through its high dynamic servo controlled axles.Tread wear testerThe 2 station unitscan run with different drum surfaces.Load, camber, slip,lateral force, speedand driving forcecan be adjusted withhigh dynamic.

6Quality control:For the tireproduction processPassenger carsZF has invented different unique final finishing machinesto measure quality. The ZF-LUB5 combines the measuringof uniformity and dynamic unbalancing in one machine,in one cycle, in one test position – adding only 3 secondsto a standard uniformity cycle. Separated they are alsocapable to act as a line concept, ZF-LU5 and ZF-BAL5.High speed uniformity testing machines are designed andbuilt for high performance tire production lines to analyzealso dynamic uniformity behavior as a quality feature.Truck and busZF has developed a brand-new test bench – the ZFLUB6 TBR. This tire test bench is based on the wellknown machine types for passenger cars but especiallydesigned for truck, bus and off-highway tires. Usingstate of the art technology and improving the combinedconcept even further – with this 6th generation – leadsto a measurement performance at a whole new leveland this in less than one minute.Low speed uniformity machine LUB5The “all in one solution” offering themeasurement of low speed uniformity,dynamic unbalancing, and geometry.All final finishing products are available with optimallyintegrated options like lubrication or marking.These machines are perfectly suited for existing tiremanufacturing plants. For brownfield extensions andgreenfield projects, ZF also offers tailor-made solutionswith its comprehensive test equipment portfolio.Final finishingmachine LUB6 TBRThe ZF-LUB6 TBR isthe new final-finishtire test equipmentfor the inspection oftruck and bus radialtires.

7Even more:From tire to vehicleUltimately, the tire is just a component between the roadand the vehicle chassis. Therefore, it can be importantto qualify all or at least larger parts of the suspension.Thus, interaction between the components can be takeninto account and understood better. Besides the drivingspeed, dynamics can be generated either from the roadsurface or from targeted changes in load on the wheel.This applies to both NVH and durability aspects.Tire noise / acoustic testerfor tires and wheels for passenger cars aswell as truck & bus vehicles.Different road surfaces can be applied to thedrum, the change can be done manually orautomatically. Possible are structure bornenoise measurements at highest frequencyrange and airborne noise measurement withlowest machine noise emission.Multi axial wheel testerThe state-of-the-art multi axial wheel tester(MARP) allows extremely realistic simulationsof test piece characteristics. As a result, completely new areas in the dynamic responseand in the qualification of measured valuescan be tested.
