Interlocking transmission mechanism of forward and reverse push rods of accelerator table

Abstract

The invention discloses an interlocking transmission mechanism of forward and reverse push rods of an accelerator table. The interlocking transmission mechanism comprises a shell (1), a rotary disc (7), a limiting disc (13), a servo gear (14) and a dustproof disc (23). The interlocking transmission mechanism is characterized in that the rotary disc (7), the limiting disc (13), the servo gear (14)and the dustproof disc (23) are movably mounted on a round boss (26) of the shell (1) in sequence, the servo gear (14) is engaged with a gear (3) on a shaft of a motor (2), the reverse push rod (28) and a connecting handle (22) on the dustproof disc (23) are movably connected to a forward push handle (29), the rotary disc (7) is connected with a pull rod (27), one end of a connecting rod (9) is sleeved with a stepped shaft B (17), the stepped shaft B (17) is sleeved with bearings C (11) and bearings B (8), and the other end of the connecting rod is sleeved with a connecting table of the dustproof disc (23) through a stepped shaft A (10). The interlocking transmission mechanism has the beneficial effects of being small in size, reliable in performance, compact in structure and convenient tooperate.

Description

Technical field [0001] The invention belongs to the technical field of aircraft accessories, and specifically relates to an interlocking transmission mechanism of a forward and reverse push rod of a throttle platform. Background technique [0002] The throttle control system of the aircraft flight control system, in the traditional throttle platform, the throttle push rod is mostly used to limit the throttle position through the limit block to prevent misoperation rather than the interlocking design between the structures. If the trajectory is too long, there will be problems such as large structure, low reliability, and insufficient structural layout. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings and provide a throttle pedal forward and reverse push rod interlocking transmission mechanism with small volume, reliable performance and compact structure. [0004] The purpose of the present invention and its main technical ...

AI Technical Summary

Problems solved by technology

[0002] For the throttle control system of the aircraft flight control system, most of the throttle forward and reverse push rods on the traditional throttle platform work through the limit block to limit the position of the throttle to prevent misoperation rather than the interlocking design between structures. If the motion trajectory is too long, there will be problems such as large structural volume, low reliability, and insufficient structural layout.
