Description

Technical Field

[0001] The invention belongs to the technical field of aircraft, and in particular relates to a mechanical clutch mechanism with synchronous disengagement of multiple throttle levers in front and rear cabins, and also relates to a method for using the mechanism. Background Art

[0002] Currently, the linkage mechanism between the front and rear throttle levers of an aircraft uses a friction-type mechanical clutch mechanism, which mainly consists of the front throttle lever, a friction pair, a transmission mechanism, and the rear throttle lever. The friction-type mechanical clutch mechanism is usually installed between the throttle lever and the transmission mechanism. Under normal circumstances, the friction mechanical clutch mechanism is engaged, and the force of the front cabin throttle lever is transmitted to the rear cabin throttle lever through the friction mechanical clutch mechanism and the transmission mechanism, realizing the linkage between the front and rear cabin throttle levers. Under abnormal circumstances, the transmission mechanism is stuck. To ensure normal operation of the throttle lever, an operating force greater than the maximum friction force of the friction mechanical clutch mechanism must be used to push or pull the throttle hand lever. The friction mechanical clutch mechanism slips, ensuring that the input handle can continue to be operated and preventing the throttle lever from getting stuck. Due to the action of friction, the friction mechanical clutch mechanism is always in a slipping state, and the clutch cannot completely disengage the throttle lever and the transmission mechanism. When operating the throttle lever, the operating force must overcome the friction force of the friction mechanical clutch mechanism, which greatly increases the throttle lever operating force, significantly reduces the operating effort and comfort. When multiple throttle lever transmission mechanisms are stuck, the throttle lever operating force is too great, making it difficult to operate the throttle lever, making it inconvenient to use. Moreover, when the throttle platform needs to be restored, the throttle platform must be disassembled and adjusted to restore the friction mechanical clutch mechanism, making the throttle platform difficult to restore. Summary of the Invention

[0003] The object of the present invention is to overcome the above-mentioned shortcomings and provide a front and rear cabin throttle levers that are completely disengaged synchronously. When the front and rear cabin throttle levers need to be restored to linkage, only a reset button needs to be pulled to complete the restoration of the mechanical clutch mechanism. The mechanical clutch mechanism with multiple throttle levers disengaging synchronously for the front and rear cabins and its use method are easy to use.

The limit joint is connected to the rear cabin throttle lever, and an annular groove is processed in the middle of the limit joint. When the limit clamp falls into the annular groove, the limit joint moves with the limit bracket. When the limit clamp comes out of the annular groove, the limit joint does not move with the limit bracket; the limit bracket is connected to the front cabin throttle lever and moves with the front cabin throttle lever at any time; the limit clamp is installed on the guide rail and moves with the limit bracket; the guide rail is installed on the switch bracket to guide the limit clamp; the rocker arm is installed on the switch bracket and connected to the guide rail, and is connected to the connecting rod by rivets.
