THE WHEEL, REIN­VENTED

The Courier-Mail - Motoring - - Feature -

dual pur­pose to com­po­nents al­ready in place in an elec­tric ve­hi­cle to han­dle re­gen­er­a­tive brak­ing, par­tic­u­larly by boost­ing the per­for­mance of the in­verter and en­abling the ve­hi­cle to draw the max­i­mum charge a sta­tion can de­liver.

Mak­ing the on-board recharger re­dun­dant has the po­ten­tial to cut costs too.

An­other bonus with Al­lCharge is that it’s re­versible. It’s no prob­lem at all to pro­vide an out­put plug to de­liver power at any coun­try’s stan­dard do­mes­tic AC volt­age and fre­quency, Con­ti­nen­tal’s engi­neers say. CON­TI­NEN­TAL’S de­sign is a two-piece wheel, which also turns the con­ven­tional disc brake in­side out. De­signed with elec­tric ve­hi­cles in mind, it’s lighter, more durable and qui­eter than a reg­u­lar wheel and brake as­sem­bly.

The wheel rim and tyre are bolted to a cen­tral five-pointed “star”, which is per­ma­nently fixed to the axle. Fas­tened to the star’s points is a large-di­am­e­ter brake disc made of a tough alu­minium al­loy that Con­ti­nen­tal engi­neers say will last the en­tire life of the car.

The large di­am­e­ter of the brake disc means the brake caliper doesn’t need to bite so hard for strong stop­ping power. This, in turn, re­quires smaller and lighter hy­draulic com­po­nents. And the caliper can also be down­sized at the same time as be­ing made stiffer.

As a bonus, there is a re­duc­tion in noise when the brakes are ap­plied, the engi­neers say.

We’re ex­cited: Con­ti­nen­tal makes parts of the cabin vi­brate in lieu of au­dio speak­ers; it’s also look­ing at su­per-quick charg­ing
