Abstract
In one instance, disclosed herein is a pressure modulating clutch control assembly that includes: a valve assembly configured to apply a clutch pressure to a clutch device; a pressure modulation assembly in fluid communication with the valve assembly and configured to control a maximum pressure level that the clutch pressure reaches; and a modular relief valve in fluid communication with the valve assembly and the pressure modulation assembly, the modular relief valve forming part of a hydraulic feedback loop between the valve assembly and the pressure modulation assembly, wherein the hydraulic feedback loop is configured such that an increase in a modulation pressure of a pressurized fluid within the pressure modulation assembly causes a corresponding increase in the clutch pressure until the clutch pressure reaches the maximum pressure level.
