A NEW PRO­TO­TYPE ar­tic­u­lated bus “im­pres­sively demon­strates” sys­tem so­lu­tions to sim­plify the tran­si­tion to elec­tric-pow­ered city buses, ac­cord­ing to com­mer­cial ve­hi­cle driv­e­line and chas­sis tech­nol­ogy spe­cial­ist ZF.

The 18-me­tre ‘ar­tic’ bus is equipped with two of the “proven” AVE 130 elec­tric por­tal axles, with a to­tal of four mo­tors pro­vid­ing pow­er­ful thrust.

As the com­pany ex­plains, stricter emis­sions lim­its and the public de­bate on fine dust pol­lu­tion are putting pres­sure on public trans­port op­er­a­tors to re­duce emis­sions, mean­ing bus man­u­fac­tur­ers are in­vest­ing re­sources into sys­tem in­te­gra­tion and even more on de­vel­op­ment.

In or­der to make the tran­si­tion to lo­cal zero-emis­sion city buses and low-emis­sion lo­gis­tic trans­port trucks as easy and flex­i­ble as pos­si­ble, ZF is pro­vid­ing com­mer­cial ve­hi­cle man­u­fac­tur­ers with tech­nol­ogy and sys­tems ex­per­tise, it states.

The com­pany of­fers its AVE 130 elec­tric por­tal axle and the new CeTrax elec­tric cen­tral drive for city buses, act­ing as a one-stop shop for all the com­po­nents re­quired, says ZF. This means man­u­fac­tur­ers can choose con­ven­tional low-floor and high-floor plat­forms, as well as low-en­try buses for elec­tri­cally pow­ered mod­els, which makes the elec­tri­fi­ca­tion of ve­hi­cle fleets more eco­nom­i­cal and con­ve­nient, it adds.

In long-haul trans­port lo­gis­tics and coach ap­pli­ca­tion, elec­tric drives are no longer limited to be­ing a fan­ci­ful idea; in fact, the hy­brid ver­sion of the ZF TraXon com­mer­cial ve­hi­cle trans­mis­sion ex­hausts pre­vi­ously un­used power sav­ings po­ten­tial at max­i­mum out­put, the com­pany says.


• AVE 130 in­cludes ad­vanced in­vert­ers, drive con­trol and power elec­tron­ics all fully in­te­grated, guar­an­tee­ing op­ti­mal en­ergy ef­fi­ciency – and a larger range;

• CeTrax is built on a plug-and-drive ap­proach, so can be in­te­grated into ex­ist­ing ve­hi­cle plat­forms without ma­jor changes to the chas­sis, axles, stat­ics or dif­fer­en­tial;

• TraXon Hy­brid, with elec­tric mo­tor be­tween com­bus­tion en­gine and trans­mis­sion, al­lows hy­brid func­tions in heavy com­mer­cial ve­hi­cles.
