Active Roll Stabilizer Suspension System Relies on MOLYKOTE® Smart Lubrication™ Solution
A backlash-free, high-reduction strain-wave gearbox for an active stabilizer suspension system being used on select models of a luxury-class vehicle brand.
Faster-acting than typical hydraulically actuated roll stabilizers, the advanced electromechanical design incorporates a strain-wave gearbox, specially developed brushless motor and an electronic controller to influence torque coupling and dramatically reduce rolling movements of the vehicle.
To meet a vehicle OEM customer’s performance specifications, the manufacturer of the strain-wave gear technology needed an effective lubricant to outperform current PAO-based grease options. Key lubrication criteria included noise-damping capabilities, good lubricity with high-pressure sliding friction, good low-temperature performance, suitable grease mobility, and compatibility with gearbox elastomer seals.
The manufacturer collaborated with MOLYKOTE® application engineering specialists to identify an effective solution to meet the gearbox lubrication needs. Compared with an initial PAO/ester grease for gearbox lubrication, MOLYKOTE® G-1074 Grease delivered superior performance.
The performance properties of MOLYKOTE® G-1074 Grease compare favorably with those of the initial lubricant option for the gearbox application.
Potential advantages of MOLYKOTE® G-1074 Grease include:
Based on gearbox lubrication performance in the vehicle active suspension system, the manufacturer expects to qualify MOLYKOTE® G-1074 Grease for use in other actuator applications for robotics, farm machinery, autonomous vehicles, industrial control technologies and more. Based on industry interest, mechatronic roll stabilizer applications have sizable growth potential across multiple vehicle platforms.
