The invention belongs to the technical field of mechanical, electrical and hydraulic servos, and specifically discloses a small-sized integrated pressure-output braking control device. The small-sizedintegrated pressure-output braking control device comprises a motor, a decelerating mechanism, a lead screw, a piston, a first pressure sensor, a second pressure sensor, a braking controller and a hydraulic oil chamber, wherein the output shaft of the motor is connected with the input end of the decelerating mechanism; the output end of the decelerating mechanism is connected with the input end of the lead screw; the output end of the lead screw is connected with the piston; the piston is embedded in the hydraulic oil chamber; the pressure signal acquisition ends of the first pressure sensorand the second pressure sensor are both inserted in the hydraulic oil chamber; the pressure signal output ends of the first pressure sensor and the second pressure sensor are both connected with the signal input end of the braking controller; and the output shaft of the braking controller is connected with the input shaft of the motor. The small-sized integrated pressure-output braking control device can be arranged in a small-sized aircraft to achieve the braking function. A mechanical part and a control part are combined to achieve the braking pressure output. The small-sized integrated pressure-output braking control device is small in size and easy to install and test.

Description

technical field [0001] The invention belongs to the technical field of electromechanical hydraulic servo, in particular to a small integrated pressure output brake control device. Background technique [0002] The braking system is an important part of the aircraft, and its performance has a great impact on the safety performance of the entire aircraft. Since the current aircraft is developing toward miniaturization and unmanned, higher requirements are placed on the structure and performance of the brake control device. Due to the small space available in the small aircraft and the high performance requirements for the brake control device, the integration and miniaturization of the brake device has become the key to the design.

AI Technical Summary

Problems solved by technology

[0003] At present, the brake devices of small aircraft mostly adopt the form of pure hydraulic or pure electromechanical, and the mechanical part and the control part are separated independently, so the volume is large, which is not conducive to the light weight and miniaturization of the whole machine, and cannot fully realize the brake system. high performance indicators

[0004] The reason for the above-mentioned problems is that the current brake control device cannot integrate the advantages of the machine, electricity and hydraulics into one.
