WABCO pi­o­neers air sus­pen­sion tech­nol­ogy for elec­tric SUVs

Auto components India - - CONTENTS - ACI

WABCO, a lead­ing global sup­plier of tech­nolo­gies and ser­vices that im­prove the safety, ef­fi­ciency and con­nec­tiv­ity of com­mer­cial ve­hi­cles, will sup­ply a ma­jor Ger­man pas­sen­ger car maker its break­through elec­tric twin com­pres­sor air sus­pen­sion tech­nol­ogy. WABCO is ex­pected to equip all the premium elec­tric sport util­ity ve­hi­cles (SUVs) of the cus­tomer in global se­ries pro­duc­tion start­ing in late 2018.

This new long-term sup­ply agree­ment fur­ther strength­ens WABCO’s lead­er­ship po­si­tion as the pas­sen­ger car in­dus­try’s sole sup­plier of elec­tron­i­cally con­trolled air sup­ply sys­tems for elec­tric-pow­ered pas­sen­ger ve­hi­cles. The air sup­ply sys­tem on elec­tric ve­hi­cles low­ers the body at high speeds, re­duc­ing aero­dy­namic drag and, there­fore, im­proves en­ergy con­sump­tion. It also en­ables in­tel­li­gent low­er­ing of the ve­hi­cle when parked to op­ti­mise in­duc­tive elec­tric charg­ing, elim­i­nat­ing need for ca­ble con­nec­tions. The pi­o­neer­ing en­gi­neer­ing of WABCO for premium elec­tric SUVs in­cludes its com­pact air sup­ply with built-in twin com­pres­sors, re­sult­ing in an in­no­va­tive high-per­for­mance air sup­ply sys­tem. This in­dus­try-first in­ven­tion dif­fer­en­ti­ates by in­creas­ing rate of air­flow by 40% and by aug­ment­ing max­i­mum air pres­sure up to 15% along­side su­pe­rior acous­tic per­for­mance.

WABCO’s com­pres­sors also start elec­tron­i­cally, rather than elec­trome­chan­i­cally, which softly re­duces the start­ing elec­tric cur­rent by 50%. This tech­nol­ogy op­er­ates vir­tu­ally in si­lence, an­other dif­fer­en­tia­tor that elim­i­nates noise, and en­ables quiet rid­ing in lux­ury pas­sen­ger ve­hi­cles.

“Au­tomak­ers are con­tin­u­ing to em­pha­size elec­tri­fi­ca­tion, and we see a trend to­ward a ris­ing num­ber of elec­tric ve­hi­cle mod­els around the world, which call for in­creas­ingly ef­fi­cient air com­pres­sion at high pres­sures while re­tain­ing en­ergy,” Philipp Helmich, WABCO Vice Pres­i­dent, Orig­i­nal Equip­ment Sales and Key Ac­count Man­age­ment, said. “Fur­ther demon­strat­ing WABCO’s tech­nol­ogy lead­er­ship, our new twin com­pres­sor is at the heart of to­mor­row’s air sus­pen­sion sys­tems for premium elec­tric pas­sen­ger cars and sport util­ity ve­hi­cles.” WABCO has fur­ther dif­fer­en­ti­ated its twin com­pres­sor sys­tem with an op­tional boost func­tion, which in­creases the air reser­voir’s en­ergy ca­pac­ity over three­fold. This means the size of the reser­voir can be sig­nif­i­cantly de­creased, which helps re­duce ve­hi­cle weight.
