装置。 Hydraulically operated differential lock devices for four-wheel drive vehicles include a four-wheel drive detection sensor that detects the four-wheel drive state and outputs a signal, and a gear sensor that detects the gear range state of the auxiliary transmission and outputs a signal. a range detection sensor, a vehicle speed sensor that detects vehicle speed and outputs a signal corresponding to the vehicle speed, a bypass circuit attached to the hydraulic circuit of the differential lock device, a hydraulic solenoid valve that opens and closes the bypass circuit; When it is determined that the vehicle is in two-wheel drive by inputting the output signals from the wheel drive detection sensor, gear range detection sensor, and vehicle speed sensor, or when the vehicle speed exceeds the set speed and the gear range is set to low.
A differential lock operation limiting device comprising: a control circuit that outputs a control signal to open the hydraulic solenoid valve when it is determined that the range is not in the range.
