置。[Scope of claim for utility model registration] (1) A pressure sensor that detects the pressure of the boom cylinder on the input side, a rotation sensor that detects the speed of the axle shaft, a brake pedal that can be switched between automatic and manual, and a brake pedal that is on the output side. A controller is interposed between the proportional solenoid valve, and the controller is an on/off (ON, OFF) signal detection circuit, has an A/D converter, and a rotation speed detection circuit, and calculates the optimum brake pressure. An automatic brake control device for a wheel loader, characterized by having a built-in computer that outputs a setting signal via a proportional solenoid valve drive circuit. (2) The brake for a wheel loader according to claim 1 of the utility model registration claim, wherein the pedal that can be switched between automatic and manual has a two-stage spring and uses a mechanical variable pressure regulating valve. Automatic control device.
