Power management company Eaton has expanded its UltraShift Plus automated transmission offerings with a new A-Ratio model specifically designed for a wide range of extreme performance applications. The new MXP (Multipurpose Extreme Performance) transmissions have lower overall numerical ratios and higher torque ratings.
The ratios and even steps on the new transmissions deliver better shift performance to improve grade shifting in hilly and mountainous conditions. The 18-speed A-Ratio transmissions, when designed into the appropriate driveline, can allow for unlimited payloads.
“These new A-Ratio transmissions are ideal for demanding applications such as those encountered on routes where steep grades are present and when vehicles are pulling extra heavy payloads,” said Ryan Trzybinski, product planning manager for Eaton.
Production begins this month. The standard UltraShift Plus warranties, which are dependent on application, remain the same for the newest application expansion to Eaton’s lineup of automated transmissions.
As part of the Performance Series of UltraShift Plus transmissions, the A-Ratio transmissions use an electronic clutch actuator to provide faster shifting and smoother engagement. At idle, Eaton says, the clutch fully engages giving drivers excellent control in challenging situations. Shift selection software uses changes in grade, weight and throttle control to calculate the most efficient and effective shift points.
