AI Technical Summary

Problems solved by technology

Most of the existing airborne joystick damping devices are contact friction non-adjustable designs, and the stability of the control force index is not ideal due to random load environment changes, which greatly restricts the demand for control force for different tasks.

Embodiment Construction

[0015] The specific embodiments of the present invention will be further described in detail below.

[0016] After the friction damping device is installed, the preload gear 13 is connected with the fan gear of the throttle lever system and the force adjustment knob to change the positive pressure of the friction pair, adjust the output torque of the preload gear 13, and realize the adjustment of the throttle lever operating force. The frictional damping device provides the base force of the throttle lever, and can continuously adjust the control force of the throttle lever online. The specific implementation is as follows:

[0017] After installing the frictional damping device on the accelerator console, remove the connecting screw 3 first, and disconnect the adjustment assembly 1 and the preload assembly 2, such as figure 2 As shown, rotate the gear pair 16 to ensure that the large disc spring 21 has no extrusion effect on the friction pair, adjust the position of the lock...

Abstract

The invention belongs to the field of application development of airplane throttle control systems and relates to a friction damping device for a throttle platform. The friction damping device is characterized in that the friction damping device is in integrated modular design and is directly mounted on a throttle platform shell and connected with a throttle rod system fan gear and a force adjusting knob to provide control force for a throttle rod; the friction damping device adopts a double-contact friction pair, so that the control force of the throttle rod can change along with changing ofpositive pressure of the friction pair; the friction damping device is composed of an adjusting component (1) and a pre-tightening component (2) which are connected through connection screws (3) to form a whole. The problem that conventional damping devices cannot realize outer-field adjusting is solved, and the friction damping device is slightly influenced by environment temperature and is convenient in mounting and high in maintainability.

Description

technical field [0001] The invention belongs to the field of application and development of aircraft throttle control systems, and relates to an externally adjustable throttle lever control force friction damping device, which is used for providing the control force of the throttle lever and realizing online continuous adjustment of the control force. Background technique [0002] Modern manned aircraft airborne artificial force-sensing devices use dampers to realize stick force feedback. Comfortable control force is of great significance to improve the smoothness and maneuverability of pilot control. Most of the existing airborne joystick damping devices are contact friction non-adjustable designs, and the stability of the control force index is not ideal due to random load environment changes, which greatly restricts the demand for control force for different tasks. [0003] Provide a set of friction damping device for aircraft throttle console. The device can provide a s...
