THE rise of elec­tric trucks con­tinue un­abated in the U.S.

Af­ter Mack and BYD last month an­nounced their plan to use elec­tric-tur­bine and full-elec­tric trucks and the Nikola 1 truck in­spired over 7 000 de­pos­i­tors to part with $1 500 (R21 800) each, clutch maker Ea­ton last week an­nounced will make a gear­box specif­i­cally for elec­tric trucks.

Ea­ton said it is in­volved in a pro­duc­tion pro­gramme with Pi In­novo and UQM Tech­nolo­gies to make a twospeed gear trans­mis­sion, which will link to UQM’s Pow­erPhase HD220/ HD250 mo­tor and in­verter sys­tem to cre­ate a full elec­tric driv­e­train sys­tem called the “UQM Pow­erPhaseDT”.

Ea­ton stated its two-speed trans­mis­sion will pro­vide a greater speed and torque range from what would nor­mally be pos­si­ble in a di­rect drive sys­tem, al­low­ing a smaller elec­tric mo­tor to drive large ve­hi­cles.

The smaller driv­e­train will also al­low for bet­ter pack­ag­ing, ef­fi­ciency, greater pay­load ca­pac­ity and lower cost when com­pared with di­rect drive or sin­gle speed driv­e­train strate­gies.

The trio plan to start pro­duc­tion early next year.


Fu­ture truck trans­mis­sions will be­come as small as this, from the half-a-ton cas­ings of to­day (be­low).
