The invention relates to the technical field of helicopter wheel brake, in particular to a helicopter wheel brake transmitter with an output pressure control function, which comprises a valve rod, a sleeve, a shell, a piston, an end cover, a push rod and a valve seat, the valve rod is in threaded connection with the sleeve, the piston is slidably mounted in the shell, the valve seat is slidably mounted in the shell, and the end cover is arranged on the valve seat. The valve rod penetrates through the valve seat and extends into the piston, the valve rod is connected with the piston through a pin, the end cover is installed on the shell, and the push rod is in threaded connection with the sleeve. The function of converting force applied to a brake pedal by a pilot into hydraulic pressure to be output and the function of controlling the highest output pressure are achieved, the situation that a brake distribution valve is damaged due to excessively-high output pressure is avoided, faults are avoided, and normal flight of a helicopter is guaranteed; and the observation window is arranged to observe the storage amount of oil in the airplane wheel brake transmitter, use and maintenance of maintenance are facilitated, use safety is improved, practicability is good, and great practical value is achieved.
