Title:
FREEWHEEL HYDRAULIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2014/014985
Kind Code:
A3
Abstract:
The present disclosure relates to a hydraulic drive having a stationary housing. The hydraulic drive also has a drive shaft that extends through the stationary housing. Furthermore, the hydraulic drive has a hydraulic motor for rotating the drive shaft relative to the stationary housing. Additionally, the hydraulic drive includes a driven hub adapted to be connected to a rotatable driven element. The hydraulic drive also has a coupling/decoupling arrangement that allows the hydraulic drive to be operated in an engaged mode where the drive shaft is coupled to the driven hub in a direct drive arrangement and a disengaged mode where the drive shaft is decoupled from the driven hub. When the hydraulic drive is operated in the engaged mode torque from the drive shaft is transferred to the driven hub causing the driven hub to rotate relative to the stationary housing. When the hydraulic drive is operated in the disengaged mode the driven hub can free wheel relative to the drive shaft.
