Xtrac Launch Dual Motor Ev Transmission To Adapt Torque Vectoring
Xtrac’s P1227 gearbox household unit of measurement has been developed to address the growing marketplace seat requirement for unmarried speed, lightweight in addition to mightiness dense electrical vehicle (EV) transmissions. It offers a make of installation possibilities for fast in addition to powerful electrical supercars amongst front-wheel drive, nurture bicycle make or four-wheel make configuration.
“There is substantial conception in addition to intellectual belongings inward the pattern of this novel transmission system,” says James Setter, caput of Xtrac’s Automotive in addition to Engineering job organisation unit, which focuses on developing transmission systems for hypercars, hybrids in addition to EVs to complement the company’s world-beating motorsport transmissions. “Significant focus went into the integration of the gearbox amongst numerous proprietary traction motors, in addition to inward particular, reducing its volume yesteryear nearly xx per cent compared amongst our previous P1092 electrical vehicle transmission to render the ultimate electrical make transaxle.”
The novel transmission arrangement tin forcefulness out survive integrated amongst motors supplied yesteryear BorgWarner, GKN in addition to YASA, all of whom worked amongst Xtrac on the integration of their engineering into this transmission. The dual electrical motors of the transmission arrangement besides render an inherent torque vectoring capabilities. For lower mightiness applications a unmarried electrical motor tin forcefulness out survive specified, reducing the overall vehicle weight farther in addition to requiring an fifty-fifty smaller infinite envelope. The highly configurable nature of the pattern besides enables an opened upward or a express skid differential to survive specified.
In addition, the P1227 household unit of measurement of gearboxes offers a make of unmarried gear ratios, equally good equally considerable motor-generator configuration in addition to thence vehicle installation possibilities. This enables the transmission, for example, to survive installed inside a 90-degree angle from the motors positioned vertically higher upward through to horizontally inward front end of the output.
“The pattern draws on Xtrac’s precision design, analysis in addition to manufacturing engineering capabilities,” says Setter, “ensuring that the solid set down helical gear sets, necessary for route vehicle transmission systems, offering special levels of NVH refinement for the most demanding still driveline electrical vehicle applications, equally good equally the durability required for this marketplace.”
The transmission has been designed equally a household unit of measurement to integrate amongst either YASA P400, GKN AF130 or AF230 or BorgWarner HVH-250-090-SOM or HVH-250-115-DOM motors, exactly other motors could survive suitable equally long equally the RPM of the motor is less than 10,000rpm, in addition to the peak torque is less than 500Nm per motor similar the xc kW / 300 Nm Evans Electric axial flux induction motor.
