Document Type and Number:
Japanese Patent JP6454264
Kind Code:
B2
Abstract:
To reduce increase of the temperature of a control device of a supercharger and increase the lifetime of the control device of the supercharger, a work machine includes a variable geometry supercharger having changeable supercharge pressure and a working device. The work machine includes a variable displacement work hydraulic pump configured to be driven by an engine and supply pressure oil to an actuator configured to drive the working device; a supercharger control device configured to control the supercharger; a temperature detection device configured to detect the temperature of the supercharger control device; and a main control device configured to restrict, in case the temperature of the supercharger control device is higher than a first temperature, a maximum absorbing torque of the work hydraulic pump as compared to case the temperature of the supercharger control device is lower than the first temperature.
