Meritor provides new ProTec Series 30 HMIS

Meritor Inc displayed the new ProTec Series 30 High Mobility Independent Suspension (HMIS) and drivetrain at the Association of the United States Army's (AUSA) annual meeting and exposition recently. The ProTec Series 30 was developed for the HMMWV Modernized Expanded Capacity Vehicle (HMMWV MECV) and uses combat-proven components that require no additional modifications for the MECV.

“In adapting the Meritor ProTec Series 30 system to the HMMWV, we paid specific attention to issues experienced in the combat zone with the current up-armored platforms,” said Ed Eshelman, director, engineering, Meritor. “Primarily, we concentrated on suspension performance and how that relates to both stability and durability issues.”

The ProTec Series 30 HMIS was engineered to offer enhanced performance through increased wheel travel, a higher steering angle, and improved roll stability and ride quality. It will easily adapt to the existing HMMWV architecture with no further upgrades necessary beyond those previously specified for a recapitalized HMMWV.
