摘要： The axial lengths of coupling portions of a flywheel, a rotor shaft, and a pump shaft are reduced to reduce the axial length of an entire power unit. A crankshaft and a flywheel are directly coupled to each other and the flywheel and a rotor shaft are directly coupled to each other. A coupling is directly coupled to an end face of the rotor shaft on the opposite side to the flywheel. A pump shaft is connected to the coupling. Coupling surfaces of the flywheel and the rotor shaft and coupling surfaces the rotor shaft and the coupling are arranged within a width range of a coil.

摘要： A hybrid construction machine that enables to efficiently cool a generator motor, while suppressing an increase in the entire length of a power unit. A motor housing is provided with a bulging portion which is configured to axially bulge from the inner periphery of a motor side connection surface toward an engine over the entire circumference thereof around an axis, and to engage with the inside of an engine housing; and a coolant passage which is configured to flow a coolant for cooling a stator therethrough. The inner peripheral surface of the motor housing including the inner peripheral surface of the bulging portion is configured to come into plane contact with the outer peripheral surface of the stator. The coolant passage is disposed at a position axially displaced from the motor side connection surface.

摘要： A hydraulic control system for a working machine according to the present invention includes a regulator control valve for controlling an operation of a pump regulator and a controller for sending a control signal for changing a discharge quantity of the pump to the regulator control valve in accordance with an operation amount of an operating means. On the basis of the control signal, a secondary pressure in the regulator control valve is fed to the pump regulator. This system further includes a fail-safe valve disposed in a control line joining the pump regulator and the regulator control valve. The fail-safe valve has an ordinary position for sending the secondary pressure to the pump regulator and a fail-safe position for sending an oil pressure from a path other than the regulator control valve to the pump regulator in such a manner that a predetermined discharge amount is ensured. The fail-safe valve is configured so as to switch from the ordinary position to the fail-safe position in accordance with a failure signal indicative of failure in the regulator control valve. According to this, while adopting an electronic control system for the pump, it is possible to continue a work even in the failed condition of the system.
摘要翻译：根据本发明的用于工作机械的液压控制系统包括：调节器控制阀，用于控制泵调节器的操作;以及控制器，用于发送用于将泵的排出量改变到调节器控制阀的控制信号，操作装置的操作量。基于控制信号，调节器控制阀中的二次压力被供给到泵调节器。该系统还包括设置在连接泵调节器和调节器控制阀的控制线中的故障安全阀。故障安全阀具有用于将二次压力发送到泵调节器的普通位置和用于将油压从调节器控制阀以外的路径发送到泵调节器的故障保护位置，使得预定的排放数量得到保证。故障安全阀被构造为根据指示调节器控制阀故障的故障信号从普通位置切换到故障安全位置。据此，在采用泵的电子控制系统的情况下，即使在系统的故障状态下也可以继续工作。
