eDrives, Hybrids, Transaxles and Couplers
KBE+, Inc. has completed the conceptual layout through prototype build and test of four transaxles for fully-electric vehicles. We also completed and/or assisted with developing three hybrid drivetrain systems. These development activities included all aspects of project management from concept to final prototype testing.
We were also instrumental in designing and developing the mechanical aspects of two airframe-based drive systems for all-electric planes. Both are currently going through certification. analysis and development of gears, gear systems and power transmission systems all the way to complete gear-box evaluation.
An e-Drive Development Success Story
KBE+ was contracted by Animatics, a division of Moog, to design and develop a one-speed transmission (transaxle) for an electric vehicle (EV) application. This transmission was to be driven by a 50 (kW) electric motor and provide an appropriate ratio to power an approximately 2,500 (lb.sm) vehicle for on-highway use. There are four variants of the base design: two based on tapered roller bearings and two based on high angular contact ball bearings. Each of the two bearings designs can be built with either an output spool (for single side output) or a differential (for two output shafts on either side of the transmission case). KBE+ also provided design options for either a traction aiding differential or integration of a traction control system.
The final design met all specifications and client-provided criteria. It was completed on-time and within budget from a design and prototype / short-run manufacturability standpoint. Animatics then directed KBE+ to develop a vendor base to produce the final design and provide manufacturing support through the first production runs. We assumed all manufacturing responsibility and worked with all vendors involved to produce a production ready transmission.
