Title:
HYDRAULIC CLOSED CIRCUIT MOTORIZATION SYSTEM AND METHOD FOR CONTROLLING DRIVING OF TRANSPORT VEHICLE
Document Type and Number:
Japanese Patent JP2022111995
Kind Code:
A
Abstract:
To provide an emergency unit for a hydraulic closed circuit motorization system for a transport vehicle.SOLUTION: A transport vehicle (1) is driven by a hydraulic closed circuit system (6) that has a variable displacement pump (7) for sending an operating fluid to a delivery branch (9) and receiving the operating fluid from a return branch (10), a plurality of hydraulic motors (4) connected to the delivery branch (9) and to the return branch (10) for driving relative wheels of the vehicle, and a command and control unit (11) for controlling the pump (7) and the hydraulic motors (4) in an ordinary advancing condition of the vehicle (1). The command and control unit is configured to intervene in the case of failure or malfunction of the pump and to control a valve (18) so as to establish connection between the delivery branch (9) and the return branch (10) regardless of control of the pump (7) and of the hydraulic motors (4) by the command and control unit (11).SELECTED DRAWING: Figure 1
