P1227 INTEGRATED LIGHTWEIGHT ELECTRIC VEHICLE (ILEV) TRANSMISSION
The new Xtrac P1227 Integrated Lightweight Electric Vehicle (ILEV) gearbox family has been developed to address the growing market requirement for single speed, lightweight and power dense EV transmissions.
The design draws on Xtrac’s precision design and manufacturing engineering capabilities with a specific focus on ensuring the ground helical gear sets adopted for this transmission are silent for the most demanding electric vehicle applications.
The transmission has been designed as a family to integrate with either YASA P400, Avid AF130 or AF230, Integral Powertrain or BorgWarner HVH-250-090-SOM or HVH-250-115-DOM motors, but other motors could be suitable as long as the RPM of the motor is less than 10,000rpm, and the peak torque is less than 500Nm per motor.
The additional benefit of this transmission family is that it can be installed within a 90 degree angle from motor vertically above the output, through to motor horizontally in front of the output, and can be configured into one of three unique arrangements.
