An embodiment of the invention provides a motor assembly, a walking driving system and a working machine. The motor assembly comprises a motor, a brake, a brake control valve and a slide valve set. The brake control valve is connected with the brake. The brake is connected with the motor. The brake control valve can control the brake to release braking action or form braking action. The slide valve set is connected between an oil inlet way of the motor and an oil return way of the motor so as to control connection or disconnection of the oil inlet way of the motor and the oil return way of the motor. According to the motor assembly, when a main machine of the working machine breaks down, the brake can release braking action through an external oil source, the oil inlet way and the oil return way of the motor are connected, and therefore the working machine is dragged into a non-working area. Thus, economic losses caused when the working machine cannot be dragged into the non-working area due to the fact that the main machine breaks down can be greatly reduced.
本发明实施例提供了一种马达总成、行走驱动系统及作业机械。马达总成包括:马达、制动器、制动器控制阀和滑阀组。所述制动器控制阀与所述制动器连接。所述制动器与所述马达连接。所述制动器控制阀能够控制所述制动器解除制动动作或形成制动动作。所述滑阀组连接在所述马达的进油油路和所述马达的回油油路之间,以控制所述马达的进油油路与所述马达的回油油路的连通或者截止。该马达总成能够在作业机械主机出现故障时,通过外接油源使制动器解除制动动作,并使马达的进油油路和回油油路接通,从而使作业机械被拖行至非作业区域内。由此,能够极大降低由于主机故障,作业机械无法被拖行至非作业区域所导致的经济损失。
