Sealed un­til death do us part

New driv­e­line tech­nol­ogy

Big Rigs - - TECH TALK - Bob Ri­ley

TIMES are a-chang­ing as the No­bel Prize-win­ning bard once sang. Ex­tended ser­vice times for cars and trucks, more ef­fi­cient lu­bri­cat­ing prod­uct and lube-ad­min­is­ter­ing tech­nol­ogy, it only had to be a mat­ter of time.

Now ‘sealed-for-life’ driv­e­lines are avail­able in Aus­tralia from Mer­i­tor.

The Per­malube RPL Se­ries driv­e­lines were the first in the North Amer­i­can heavy-duty com­mer­cial ve­hi­cle in­dus­try to be per­ma­nently lu­bri­cated and sealed for life.

The RPL se­ries of­fers re­duced op­er­at­ing and main­te­nance costs, in­dus­trylead­ing war­ranties, easy ser­vice­abil­ity and ex­tended U-joint life, par­tic­u­larly on gear-fast/run-slow driv­e­trains and higher torque ap­pli­ca­tions.

The RPL driv­e­lines have high torque-rated mod­els avail­able for de­mand­ing ap­pli­ca­tions, in­clud­ing heavy ser­vice and down­speed­ing.

They also fea­ture: ex­tended univer­sal joint life; a four-bolt de­sign for easy in­stal­la­tion and ser­vice; and their E-coated steel guard se­cures and pro­tects the slip seal against con­tam­i­nants and dam­age.

Triple-lip seals pro­vide the ul­ti­mate pro­tec­tion against con­tam­i­nants, ny­lon thrust wash­ers elim­i­nate metal-to-metal con­tact, pre­vent­ing wear and a self-align­ing cen­tre bear­ing is stan­dard.

The RPL35 Se­ries driv­e­lines are de­signed for de­mand­ing ap­pli­ca­tions, such as heavy ser­vice and down­speed­ing where th­ese ap­pli­ca­tions typ­i­cally place higher torque de­mands on the driv­e­train sys­tem.

The RPL35 Se­ries driv­e­lines ac­com­mo­date the in­creased en­gine torques and dis­trib­ute it more evenly through­out the sys­tem.

Mer­i­tor says the RPL driv­e­lines are en­vi­ron­men­tally ‘green’ be­cause the need to grease the driv­e­line is elim­i­nated.

Mer­i­tor’s P600 Se­ries heavy-haul plan­e­tary axles de­buted in Aus­tralia at the Brisbane Truck Show.

Th­ese plan­e­tary drive axles are en­gi­neered and man­u­fac­tured to de­liver higher ca­pac­ity and im­proved per­for­mance across a mul­ti­tude of heavy-duty off-high­way ap­pli­ca­tions.

Mer­i­tor plan­e­tary axles are known for ex­cep­tional qual­ity, strength and tough­ness, and each axle is backed by an in­ten­sive val­i­da­tion process at Mer­i­tor’s global de­sign and test­ing cen­tres.

“The P600 is at­tract­ing strong lev­els of in­ter­est with many Aus­tralian cus­tomers in min­ing and heavy haul ap­pli­ca­tions at­tracted by the ro­bust build qual­ity and the higher load rating,” Mer­i­tor sales and mar­ket­ing man­ager Michael Snell said.

The P600 plan­e­tary axle se­ries of­fer max­i­mum gross axle weight rating (GAWR) up to 38,000kg for the se­ries’ tan­dem axles and 57,000kg for se­ries’ tri­dem axles and max­i­mum gross com­bi­na­tion mass rating (GCM) up to 200,000kg for the se­ries’ tan­dem axle and 250,000kg for se­ries’ tri­dem axles.

Other im­por­tant fea­tures of the P600 se­ries in­clude: a driver-con­trolled dif­fer­en­tial lock which will max­imise trac­tion; anti-lock brak­ing sys­tem ca­pa­bil­ity; a non-vented brak­ing drum to pro­tect the brak­ing sys­tem; and a fab­ri­cated steel hous­ing fit­ted with brack­ets that will ac­cept all heavy duty sus­pen­sions avail­able on the mar­ket.

Driv­e­lines are en­vi­ron­men­tally ‘green’ be­cause the need to grease the driv­e­line is elim­i­nated.
