Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention is further described:

[0016] Such as figure 1 As shown, a positive and negative push interlock mechanism includes a reverse push rod 1, a positive push rod 2, an intermediate baffle plate 3, and a pin shaft 5; the positive push rod 2 includes a connecting rod a6, a connecting rod b7, a lock arm 4. Cam assembly; connecting rod a6, connecting rod b7, lock arm 4 and the cam assembly are installed inside the forward push rod 2 through hinges, the reverse push rod 1 is linked with the positive push rod 2, and one end of the connecting rod a6 is connected to the reverse push rod The rod 1 is connected by a hinge, and the other end is connected to the lock arm 4, so that the anti-push rod 1, the connecting rod a6, and the lock arm 4 constitute a four-bar linkage mechanism; one end of the connecting rod b7 is connected to the lock arm 4, and the other end Connected with the cam mechanism, the connecting ro...

Abstract

The invention belongs to a flying automatic control technology, and relates to a forward and reverse thrusting interlocking mechanism. The forward and reverse thrusting interlocking mechanism is usedin an accelerator control console of an airborne power device system, and can also be used in other electromechanical products. The forward and reverse thrusting interlocking mechanism comprises a reverse thrusting rod (1), a forward thrusting rod (2), a middle baffle (3) and a pin shaft (5). The forward and reverse thrusting interlocking mechanism integrates the forward thrusting rod and the reverse thrusting rod, the structure is compact, and relatively independent movement is realized while the interlocking function is achieved, without occupying excessive space; the middle baffle is designed, so that the function of physical isolation from other channels is realized while the forward and reverse thrusting interlocking function is achieved, and the weight reduction design of the productis realized under a certain condition; and the forward and reverse thrusting interlocking function is realized through mechanical parts, the structure is simple and reliable, and the safety is high.

Description

technical field [0001] The invention belongs to the flight automatic control technology, which is used in the throttle console of the airborne power plant system, and can also be used in other electromechanical products, and relates to a forward and reverse thrust interlocking mechanism. Background technique [0002] The forward and reverse thrust function is widely used in military and civilian large aircraft at home and abroad. For large aircraft that pursue safety, how to avoid misuse and how to realize the forward and reverse thrust self-locking function has become a hot spot of research. At present, foreign applications The interlocking technology of electrical appliances has the risk of failure of electronic components, which is not as reliable as the mechanical one. At present, there is no forward and reverse thrust interlocking mechanism with an integrated design of forward and reverse thrust connecting rods on large aircraft. Contents of the invention [0003] Th...
