Example Embodiment

[0038] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the discussed preferred embodiments only exemplarily illustrate specific ways to implement and use the present invention, and do not limit the scope of the present invention.

[0039] The core idea of ​​the present invention is that through the mechanism design, the detection mechanism first stores a certain potential energy in a mechanical / physical manner. When the over-travel lever / ejector moves to a certain position, it can trigger the detection mechanism to release the potential energy and convert it into a target Movement, change the target position, so as to achieve detection.

[0040] See figure 1 , Shows a schematic structural diagram of the aircraft turning stroke detection device according to the present invention. The aircraft turning over-travel detection device 100 of the present invention includes an ove...

Abstract

The invention provides an airplane swerve over-travel detecting device. The airplane swerve over-travel detecting device comprises an over-travel push rod and a detecting assembly, wherein the detecting assembly comprises a target, a proximity detector, a sleeve, an energy storage spring, a connecting rod and a linkage clamping hook. When swerve over-travel occurs, the linkage clamping hook is opened through the over-travel push rod so as to loosen the connecting rod, the connecting rod is driven to drive the target by the energy storage spring towards the proximity detector, and the proximity detector detects the position of the target and send signals to an airplane control system. The airplane swerve over-travel detecting device is beneficial to detecting swerve over-travel and not prone to wrong detection and false-alarm. The target is not destroyed in a detecting process, and the over-travel state is locked in a mechanical mode when the over-travel state occurs. The over-travel state can be discovered by crew members easily and hand reset can be carried out.

Description

technical field [0001] The invention belongs to the technical field of self-detection of an aircraft turning system, and relates to a non-destructive detection device for an over-travel of an aircraft turning. Background technique [0002] Modern aircraft, especially large civil aircraft and transport aircraft, generally have a front wheel steering system, which converts hydraulic energy and electrical energy into rotation of the front wheels. [0003] Common turning actuation forms include rack and pinion and push-pull actuators, and the actuation principles of these forms are known. Due to structural design reasons, the steering angle of most front wheels is designed with a maximum allowable value. Continued rotation after exceeding this angle may cause disengagement or damage of the transmission mechanism. Therefore, after reaching this critical angle, it is necessary to automatically disengage the steering system. And remind the pilot or maintenance of this state throug...
