Description

Technical Field

[0001] This invention belongs to the field of throttle technology, specifically relating to a four-way parallel throttle lever operating force adjustment mechanism with a linkage locking device. Background Technology

[0002] The throttle console is a crucial device for pilots to control aircraft thrust, directly impacting the aircraft's handling characteristics. The magnitude and smoothness of the throttle lever's operating force are key ergonomic indicators of the throttle console. Currently, throttle consoles commonly use mechanical damping. Since the damping adjustment mechanism is mostly located within the throttle console's internal structure (protected by an external cover or housing), limitations in product size and onboard installation and operating space necessitate the removal of the seat or other equipment to disassemble the entire throttle console and establish operational space for maintaining its controllability. Mechanical friction presents challenges such as inconvenient friction adjustment, difficult maintenance, and poor portability. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a four-way parallel throttle lever operating force adjustment mechanism with a linkage locking device that is small in size, compact in structure, does not have a decaying basic operating force, is easy to adjust the operating force, is simple to maintain, and reduces maintenance and repair labor costs.

[0004] The present invention discloses a four-way parallel throttle lever operating force adjustment mechanism with a linkage locking device, comprising a locking rod, push rod A, push rod B, push rod C, push rod D, friction locking force adjustment mechanism, support shaft a, and support shaft b. The mechanism is characterized in that: the upper ends of the locking rod, push rod A, push rod B, push rod C, push rod D, and friction locking force adjustment mechanism are respectively connected to the support shaft b; the lower end of the friction locking force adjustment mechanism is mounted on the support shaft a.

[0005] The friction locking force adjustment mechanism consists of a screw, rivet A, stud, cotter pin, positioning ring, support plate a, rivet B, pull rod, support plate b, disc spring assembly, slider, spherical bearing, shaft, arc-shaped friction plate, bearing, gear with friction ring, bracket, spring, rivet C, large disc spring assembly, friction plate, friction ring, fixing nut disc, gear B, and gear C. The screw is riveted to the stud via rivet A. The stud passes through the positioning ring and spring and is screwed into the bracket. A cotter pin is inserted into the stud for limiting its position. The spring engages the positioning ring. The compression mechanism involves the gear below the positioning ring meshing with the gear above the bracket. Rivet C passes through the U-shaped groove on the positioning ring and inserts into the stud. The stud and pull rod are riveted together by rivet B. A disc spring assembly is fitted onto the pull rod and inserted into the slider. An arc-shaped friction plate is embedded in a spherical bearing and inserted into the slider groove for hinged connection. Support shaft a is connected to several gears with friction rings via bearings. The arc-shaped friction plate contacts the arc surface of the gears with friction rings. The slider contacts the groove on the support plate b. The gears with friction rings mesh with the gear on push rod A. The locking rod is fixedly connected to gear B, which is connected to the support shaft b via a bearing. Gear B meshes with gear C, which has a threaded structure at its center. The fixed nut disc is threadedly connected to gear C, and gear C can rotate smoothly relative to the fixed nut disc via the threaded pair. The fixed nut disc, gear C, large disc spring assembly, and friction plate are mounted on the support shaft a. Friction rings are mounted between several gears with friction rings. The gears fixedly connected to the bottom of push rods A, B, C, and D mesh with several gears with friction rings respectively. Rivet C can move up and down in the U-shaped groove on the positioning ring.

[0006] The gear with friction ring is sector-shaped.

[0007] Gear B is sector-shaped.

[0008] The gear C is sector-shaped.

[0009] Compared with the prior art, this invention has significant advantages. As can be seen from the above technical solution: a locking rod, push rod A, push rod B, push rod C, push rod D, and the upper end of a friction locking force adjustment mechanism are connected to the support shaft b, while the lower end of the friction locking force adjustment mechanism is installed on the support shaft a. A screw is riveted to a stud by rivet A. The stud passes through a positioning ring and a spring, and is screwed into the bracket. A cotter pin is inserted into the stud for limiting its position. The spring compresses the positioning ring. The gear below the positioning ring meshes with the gear above the bracket. Rivet C passes through the U-shaped groove on the positioning ring. The stud and pull rod are riveted by rivet B. A disc spring assembly is fitted onto the pull rod and inserted into the slider. An arc-shaped friction plate is placed on a joint bearing and inserted into the slider, hinged to the shaft. The support shaft a is connected to several gears with friction rings via bearings. The arc-shaped friction plate contacts the arc surface of the gears with friction rings. The slider contacts the groove on the support plate b. The gears with friction rings mesh with the gear on push rod A. The locking rod is fixedly connected to gear B, which is connected to support shaft b via a bearing. Gear B meshes with gear C, which has a threaded structure at its center. The fixed nut disc is threadedly connected to gear C, allowing gear C to rotate smoothly relative to the fixed nut disc via the threaded pair. The fixed nut disc, gear C, large disc spring assembly, and friction plate are mounted on support shaft a. Friction rings are installed between several gears with friction rings. Gears fixedly connected to push rods A, B, C, and D mesh with several gears with friction rings. Rivet C can move up and down within the U-shaped groove on the positioning ring. The relative positions of support shaft a, support shaft b, support plate a, and support plate b are fixed and connected to the platform structure on the throttle body. When the adjusting screw is turned by the screwdriver, it drives the disc spring assembly along the groove of support plate b to press the slider, and the force on the disc spring assembly is applied to the arc-shaped friction plate and the gear with friction ring. This changes the magnitude of the friction force when meshing with the gear with friction ring, thus adjusting and controlling the operating force of push rod A. The four-way assembly enables independent adjustment of the operating force of push rods A, B, C, and D. The locking rod is in the stop position in the pulling direction, and all parts on the support shaft a are in contact with each other, with none of the disc springs in the large disc spring assembly deformed or compressed. When the locking handle is pushed (to the stop position), the gear drives the gear C to rotate, moving along the threaded joint of the fixed nut disc in the X+ direction. At this time, the large disc spring assembly compresses the friction plate. Simultaneously, the friction ring gears between push rods A, B, C, and D in the damping adjustment mechanism are all subjected to the compressive force and locked together by the adjustment of the friction rings. Because they are connected to the gears on push rods A, B, C, and D, the simultaneous locking function of fixed push rods A, B, C, and D is achieved. This design achieves small size, compact structure, no attenuation of basic operating force, easy adjustment of operating force, simple maintenance, reduced maintenance, and low labor costs.

[0021] The friction locking force adjustment mechanism 6 consists of a screw 101, rivet A102, stud 103, cotter pin 104, positioning ring 105, support plate a106, rivet B107, pull rod 108, support plate b109, disc spring assembly 110, slider 111, spherical bearing 112, shaft 113, arc-shaped friction plate 114, bearing 115, gear with friction ring 116, bracket 117, spring 118, rivet C119, large disc spring assembly 201, friction plate 202, friction ring 203, fixing nut disc 204, gear B205, and gear C206. The screw 101 is riveted to the stud 103 via rivet A102. The stud 103 passes through the positioning ring 105 and spring 118 and is screwed into the bracket 117. An opening is inserted into the stud 103. Pin 104 limits the movement, spring 118 compresses positioning ring 105, gear below positioning ring 105 meshes with gear on bracket 117, rivet C119 passes through U-shaped groove on positioning ring 105 and inserts into stud 103, stud 103 is riveted to pull rod 108 by rivet B107, pull rod 108 is fitted with disc spring assembly 110 and inserted into slider 111, arc-shaped friction plate 114 is embedded in joint bearing 112 and snapped into groove of slider 111, inserted shaft 113 for hinge connection, support shaft a7 is connected to several friction ring gears 116 through bearing 115, arc-shaped friction plate 114 contacts the arc surface of friction ring gear 116, slider 111 contacts the sliding groove on support plate b109, friction ring gear 116 meshes with gear on push rod A2. Locking rod 1 is fixedly connected to gear B205. Gear B205 is connected to support shaft b8 through bearing. Gear B205 meshes with gear C206. Gear C206 has a threaded structure at its center. Fixed nut disc 204 is threadedly connected to gear C206. Gear C206 can rotate smoothly around fixed nut disc 204 through the threaded pair. Fixed nut disc 204, gear C206, large disc spring assembly 201, and friction plate 202 are mounted on support shaft a7. Friction ring 203 is mounted between several friction ring gears 116. The gears fixedly connected to the bottom of push rod A2, push rod B3, push rod C4, and push rod D5 respectively mesh with several friction ring gears 116. Rivet C119 can move up and down in the U-shaped groove on positioning ring 105. Gears 116 with friction rings are sector-shaped, gear B205 is sector-shaped, and gear C206 is sector-shaped.

When the screwdriver adjusts the screw, it will drive the disc spring assembly 110 to press the slider 111 along the slide groove of the support plate b109 through the pull rod 108. The force on the disc spring assembly 110 is applied to the arc-shaped friction plate 114 and the friction ring gear 116, thereby changing the magnitude of the meshing friction force with the friction ring gear 116 and realizing the adjustment and control of the operating force of the push rod A2.

The parts on the support shaft a7 are in contact with each other, and the disc springs in the large disc spring assembly 201 are not deformed or compressed. When the handle of locking rod 1 is pushed (to the stop position), gear B205 drives gear C206 to rotate. Gear C206 moves along the threaded pair of the fixed nut disc 204 in the X+ direction. At this time, the large disc spring assembly 201 squeezes the friction plate 202. At this time, several gears 116 with friction rings are all subjected to the squeezing force and locked together by adjusting the friction ring 203. Because they are connected to the gears on push rods A2, B3, C4, and D5, the function of locking push rods A2, B3, C4, and D5 at the same time is realized.

Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical essence of the present invention shall still fall within the scope of the present invention.
