Truck & Off-Highway Engineering - October 2022 - 10

TECHNICAL INNOVATIONS
Harbinger's initial
product line will
include electric
stripped
chassis and cab
chassis products for
Class 4 to Class 7
vehicles.
EV programs and next-generation technologies
provided the backbone for creating
a new EV platform.
" Harbinger's eAxle was developed
internally by our experienced engineering
team, " Weicker said, pointing out
that primary components - including
the permanent electric motor, gear train
and housings - are Harbinger's intellectual
property domain. The eAxle's
pending patents address various aspects,
including motor winding, lubrication,
cooling, software and control strategies
as well as the architecture.
" The electric motor and gear train are
mounted separately from the axle with
power transmitted to the wheels using
articulated driveshafts, a first in the medium-duty
commercial segment, "
Weicker said. The power-dense motor is
transversely mounted, which diminishes
efficiency losses when compared to the
losses associated with right-angle hypoid
gearing, which is used in internal
combustion engine (ICE) commercial
vehicles and is a carryover to many EV
trucks, according to Weicker.
Wheels are rigidly connected via a
novel, single-piece forged axle with a
full-floating wheel end to provide the
payload capacity and flexibility of parabolic
leaf springs. " With no prop shaft,
the entire package is located inline with
the rear axle and opens up the space in
10 October 2022

unit and electric
machine are shown

the 2022 NAIAS
media day in Detroit.
