Traction drive for internal combustion engine of commercial vehicle, has control unit for controlling drive memory valve during braking process when pressure medium connection between hydraulic machine and hydraulic accumulator is closed

摘要

The traction drive (1) has a pressure limiting valve (40), which is attached to the pressure medium flow path of a hydraulic machine (8) to a drive memory valve (38). The drive memory valve is controlled by a control unit (84) during complete opening for supercharging a hydraulic accumulator (16). The control unit is designed to control the drive memory valve during the braking process when the pressure medium connection between a hydraulic machine (8) and the hydraulic accumulator is closed.
