Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wheel brake locking mechanism, in particular to an aviation wheel left and right synchronous locking mechanism. BACKGROUND

[0002] The aircraft wheel is mainly used for dispersing the weight of the aircraft, reducing the pressure on the ground, enabling the aircraft to take off and land safely under a larger load, and improving the stability during ground sliding and parking. The wheel usually adopts a coaxial double-wheel structure. When the aircraft is parked, the wheel is locked to improve the stability and safety of the aircraft parking.

[0003] At present, in the prior art, the wheel is usually locked by inserting a pin to limit the rotation of the wheel. However, since the double-wheel wheel usually adopts a coaxial arrangement, if only one wheel is individually locked by a pin, the unlocked wheel will still rotate freely around the common axle. The rotation of the unlocked wheel will continuously exert a torsional force on the locked wheel through coaxial transmission, which will be concentrated on the pin or the contact part of the locking mechanism. Over time, the pin may be deformed or worn out, and in severe cases, the locking mechanism may be stuck or fail, affecting the stability of the locking mechanism.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the application clearer, the technical scheme in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are some embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0033] Reference Figures 1 to 5 A left-right synchronous locking mechanism for an aircraft wheel, comprising a mounting frame 1, a pair of wheels 3 is arranged below the mounting frame 1, and a connecting shaft 8 is fixedly connected between the wheels 3, a fixed rod 2 is arranged below the mounting frame 1, and a driving mechanism 5 for locking the pair of wheels 3 is arranged in the fixed rod 2.

[0034] The driving mechanism 5 comprises a sector plate 502 moving up and down, zigzag rods 503 are in sliding contact with the two sides of the sector plate 502, a moving ring 504 is fixedly connected to one end of the zigzag rod 503, an installation groove is formed in one side of the moving ring 504, a spring plate 507 is elastically installed in the installation groove, a connecting frame 505 is fixedly connected to one side of the spring plate 507, a clamping sleeve 508 is fixedly connected to one end of the connecting frame 505, a groove is formed in the surface of the connecting shaft 8, and a clamping ring 506 is fixedly installed in the groove, and the clamping ring 506 and the clamping sleeve 508 are matched.

[0035] The present application considers that when the aircraft is parked on the ground, the wheels 3 usually need to be locked so that the wheels 3 no longer rotate, thereby improving the stability and safety of the aircraft parking, but the existing wheels 3 are usually coaxial double-wheel structures, at this time, if only one of the wheels 3 is locked, the other wheel 3 may rotate, because the two wheels 3 are coaxially arranged, the locked wheel 3 may be affected by the rotating force of the unlocked wheel 3, causing the lock pin, locking device and the like used by the locked wheel 3 to be worn, jammed, and the like, affecting the stability and safety of the aircraft when parked;

[0036] Therefore, by setting the movable sector plate 502, when the sector plate 502 moves downward, the sector plate 502 will push the two sides of the folding rod 503 to move horizontally, the movement of the folding rod 503 will drive the movement ring 504 to move outward on the surface of the connecting shaft 8, the movement of the movement ring 504 will drive the synchronously moving spring plate 507, which is elastically arranged inside, to move, the movement of the spring plate 507 will drive the connecting frame 505 and the clamping sleeve 508 arranged at one end thereof to slide on the surface of the connecting shaft 8, when the clamping sleeve 508 slides to the position of the groove on the surface of the connecting shaft 8, the clamping sleeve 508 will be clamped on the surface of the clamping ring 506, thereby synchronously locking the pair of wheels 3 on both sides of the connecting shaft 8;

[0037] It should be noted that when the movement ring 504 and the clamping sleeve 508 slide outward on the surface of the connecting shaft 8, the pair of wheels 3 are in a stationary state, therefore, when the clamping sleeve 508 slides to the position of the groove on the surface of the connecting shaft 8, the clamping sleeve 508 can be clamped on the surface of the clamping ring 506, thereby locking the connecting shaft 8, and by elastically arranging the spring plate 507 on one side of the movement ring 504, when the clamping sleeve 508 slides to the position of the groove on the surface of the connecting shaft 8, the clamping sleeve 508 is clamped on the surface of the clamping ring 506, at this time, the spring plate 507 will be in a state of tension on one side of the movement ring 504, thereby enabling the clamping sleeve 508 to smoothly slide to the surface of the clamping ring 506 and be clamped thereon, thereby locking the pair of wheels 3 fixedly connected on both sides of the connecting shaft 8, improving the stability and safety of the aircraft when parked.

[0038] Referring to Figures 3 to 5 , the active mechanism 5 further comprises an electric push rod 501 detachably connected inside the mounting frame 1, the sector plate 502 is fixedly connected with the output end of the electric push rod 501, the outer side of the folding rod 503 is slidingly clamped with the shell 4, and the two ends of the shell 4 are rotatably connected with one side of the wheel 3 and fixedly connected with the mounting frame 1.

[0039] When the pair of wheels 3 needs to be locked, the electric push rod 501 inside the mounting frame 1 is started to move downward, the electric push rod 501 moves downward to drive the sector plate 502 to move downward, so that the clamping ring 506 is clamped with the clamping sleeve 508, the locking of the connecting shaft 8 is completed, and the rotation of the pair of wheels 3 on both sides of the connecting shaft 8 is limited, the stability and safety of the airplane parking are improved;

[0040] It should be noted that when the electric push rod 501 drives the sector plate 502 to move upward, since the foldable rod 503 is slidably connected with the shell 4, and the sliding position is provided with a reset element such as a reset spring, a compression spring or the like, the foldable rod 503 will be reset under the reverse action of the reset element, thereby driving the moving ring 504 to slide on the surface of the connecting shaft 8, so that the clamping sleeve 508 slides out of the surface of the clamping ring 506, and the clamping ring 506 is disconnected, the wheels 3 at both ends of the connecting shaft 8 can be quickly locked and unlocked, and the use efficiency can be effectively met.

[0041] Referring to Figures 6 to 9 , the inside of the shell 4 is provided with an auxiliary mechanism 6 for assisting the main driving mechanism 5 to lock the wheels 3, the auxiliary mechanism 6 comprises a moving frame 601 fixedly connected below the foldable rod 503, and the side of the moving frame 601 close to the surface of the connecting shaft 8 is wedge-shaped, and the lower side of the moving frame 601 is fixedly connected with a connecting ring 602.

[0042] When the two foldable rods 503 move relative to each other under the extrusion drive of the sector plate 502, the foldable rod 503 also drives the moving frame 601 to move synchronously under the sliding in the shell 4, since the side of the moving frame 601 is in sliding contact with the surface of the connecting shaft 8, the moving frame 601 can also drive the surface of the connecting shaft 8 to contact and move, and the side of the moving frame 601 close to the surface of the connecting shaft 8 is wedge-shaped, as shown in Figure 9 , the moving of the moving frame 601 can continuously exert extrusion force on the surface of the connecting shaft 8, so that the moving frame 601 also clamps the connecting shaft 8 to a certain extent, and cooperates with the clamping of the clamping ring 506 and the clamping sleeve 508, which can improve the locking effect of the connecting shaft 8, and further improve the stability of the pair of wheels 3 on both sides of the connecting shaft 8.

[0043] It should be noted that by arranging the moving frame 601 in four groups of symmetry on both sides of the connecting shaft 8, the multiple moving frames 601 can exert the same extrusion force on the surface of the connecting shaft 8 during sliding, and the contact between the moving frame 601 and the surface of the connecting shaft 8 during sliding will not affect the normal sliding of the foldable rod 503, which can effectively ensure the clamping of the clamping ring 506 and the clamping sleeve 508, and further improve the locking effect of the connecting shaft 8.

[0044] With reference to Figures 6 to 8 , the inside of the shell 4 is further provided with a locking mechanism 7 for cooperating with the auxiliary mechanism 6 to improve the locking stability of the wheel 3, the locking mechanism 7 comprises a rotating ring 701 fixedly connected with the wheel 3, one side of the moving ring 504 is rotatably clamped with a locking sleeve 702, the inside of the locking sleeve 702 is provided with a thread, the inside of the rotating ring 701 is fixedly connected with a locking ring 703, and the locking sleeve 702 and the locking ring 703 are matched.

[0045] When the folding rod 503 moves outward to push the moving ring 504 to move, the moving ring 504 slides on the surface of the connecting shaft 8 to drive the locking sleeve 702 to move to the position of the wheel 3, and the locking sleeve 702 can rotate by a certain angle during the sliding process, at this time the locking sleeve 702 can be screwed with the locking ring 703, so that the locking sleeve 702 is clamped with the locking ring 703, since the locking ring 703 is fixedly connected with the rotating ring 701, and the rotating ring 701 is fixedly connected with the wheel 3, at this time the rotating ring 701 can be rigidly connected with the locking sleeve 702, so that the rotating ring 701 no longer rotates, and further locks the wheel 3 to prevent it from rotating;

[0046] It should be noted that when the locking sleeve 702 is rotated by the moving ring 504, the locking sleeve 702 and the locking ring 703 are rotated to form a rigid connection between the rotating ring 701 and the shell 4, and the locking sleeve 702 rotates in the inside of the shell 4 at this time, after the locking sleeve 702 is screwed with the locking ring 703, the locking sleeve 702 will always contact the inside of the shell 4, thereby forming a stable connection to improve the locking effect of the wheel 3, at this time the wheel 3 and the connecting shaft 8 are locked at the same time, so that the whole is locked, which can effectively improve the stability and safety of the aircraft when parking.

[0047] With reference to Figures 7 to 8 , the auxiliary mechanism 6 further comprises a push rod 603 slidably connected with the shell 4, one end of the push rod 603 is fixedly connected with a wedge-shaped plate 604, and the wedge-shaped plate 604 is wedge-shaped, the inclined surface of the wedge-shaped plate 604 is slidably contacted with a clamping plate 605, the surface of the locking sleeve 702 is provided with a bushing, and the clamping plate 605 and the bushing are the same size.

[0048] During operation, the moving frame 601 moves, which drives the connecting ring 602 to move. The movement of the connecting ring 602 pushes the push rod 603 to slide inside the outer shell 4. The sliding of the push rod 603 drives the wedge plate 604 to slide inside the rotating ring 701. At this time, the sliding of the sliding column 704 pushes the clamping plate 605 to move through the inclined surface, so that it is inserted into the insertion hole opened on the surface of the locking sleeve 702, thereby locking the locking sleeve 702, improving the stability of the threaded connection between the locking sleeve 702 and the locking ring 703, and preventing the locking sleeve 702 and the locking ring 703 from loosening due to external vibration and other factors after the connection, which can effectively improve the locking effect of the wheel 3.

[0049] It should be noted that when the moving ring 504 pushes the locking sleeve 702 toward the position of the wheel 3, the locking sleeve 702 will rotate during the movement. After the locking sleeve 702 and the locking ring 703 are engaged, the wedge plate 604 at one end of the push rod 603 will push the locking plate 605 into the insertion hole at one end of the locking sleeve 702, thereby providing stability to the connection between the locking sleeve 702 and the locking ring 703, and thus improving the rigid connection stability between the locking ring 703 and the rotating ring 701 and the outer shell 4.

[0050] Reference Figures 8 to 9 The locking sleeve 702 has a spiral groove on its surface, and a sliding post 704 slides in contact with the inside of the spiral groove. The sliding post 704 is fixedly connected to the outer shell 4.

[0051] During operation, when the locking sleeve 702 is pushed towards the position of the wheel 3 by the moving ring 504, the locking sleeve 702 will slide into contact with the sliding column 704 through the spiral groove on its surface. At this time, the sliding column 704 is fixedly connected to the outer shell 4. Therefore, the locking sleeve 702 can rotate under the limit of the sliding column 704, thereby making it threadedly connected with the locking ring 703. Then, the wedge plate 604 pushes the clamping plate 605 to slide inside the rotating ring 701 through the inclined surface and inserts into the through hole on the surface of the locking sleeve 702, which can effectively provide reliable stability for the connection between the locking sleeve 702 and the locking ring 703.

[0052] Reference Figures 4 to 9 One end of the push rod 603 above the moving ring 504 is in sliding contact with one end of the folded rod 503. The rotating ring 701 has a slot inside, and the size of the slot is the same as that of the wedge plate 604.

[0053] During operation, when the moving frame 601 drives the lower push rod 603 to slide inside the housing 4 via the connecting ring 602, the upper push rod 603 is driven by the movement of the folding rod 503. This allows the upper push rod 603 to also drive the wedge plate 604 to move inside the rotating ring 701. Furthermore, by opening a slot with the same size as the wedge plate 604 inside the rotating ring 701, the wedge plate 604 pushes multiple locking plates 605 through the inclined surface to engage with the insertion holes on the surface of the locking sleeve 702 for limiting. At the same time, the wedge plate 604 can also engage with the slot inside the rotating ring 701, which further improves the connection stability between the locking sleeve 702 and the locking ring 703, further enhancing the locking effect on the wheel 3 and preventing unstable connection between the locking sleeve 702 and the locking ring 703, which would affect the locking effect on the wheel 3.

[0054] Reference Figure 5 and Figure 9 A return spring is provided at the sliding position of the card plate 605 and the rotating ring 701. The locking sleeve 702, the moving ring 504 and the snap sleeve 508 are all coaxially arranged. The surface of the wedge plate 604 is slidably connected to the rotating ring 701.

[0055] During operation, when the wedge plate 604 pushes the locking plate 605 into the insertion hole on the surface of the locking sleeve 702 via the inclined surface, the locking plate 605 will slide into the insertion hole in a stable posture under the reverse force of the return spring. This improves the accuracy of the fit between the locking plate 605 and the insertion hole, thereby improving the connection stability of the locking plate 605 to the locking sleeve 702 and the locking ring 703. When the wedge plate 604 stops pushing the locking plate 605 to slide via the inclined surface, the locking plate 605 can also be reset under the force of the return spring, which facilitates the continued stability of the connection between the locking sleeve 702 and the locking ring 703.

[0056] It should be noted that by arranging the locking sleeve 702, the moving ring 504, and the snap-fit ​​sleeve 508 coaxially, when the moving ring 504 and the snap-fit ​​sleeve 508 slide on the surface of the connecting shaft 8, driving the snap-fit ​​sleeve 508 to engage with the snap-fit ​​ring 506 to lock the connecting shaft 8, the locking sleeve 702 and the locking ring 703 can also precisely engage to form a threaded snap-fit, which can effectively improve the stability and efficiency of locking the connecting shaft 8 and the wheel 3, achieving the purpose of fast locking and unlocking.

[0057] Reference Figures 2 to 4 The movable frame 601 is slidably connected to the outer shell 4, and a sliding groove is provided at the lower part of the movable frame 601 where it slides with the outer shell 4. A return spring is provided at the upper part of the push rod 603 where it slides with the outer shell 4.

[0058] During operation, when the folding rod 503 moves, it pushes the upper push rod 603 to slide inside the housing 4 via the inclined surface. By setting a return spring on the surface of the upper push rod 603, not only can the stability of the push rod 603 sliding inside the housing 4 be improved, but also when the folding rod 503 stops pushing the wedge plate 604 at one end of the upper push rod 603, the upper push rod 603 will be reset under the force of the return spring, so that one end of the push rod 603 is always in contact with the inclined surface of the folding rod 503, which facilitates the folding rod 503 to push the push rod 603 to slide inside the housing 4 again.

[0059] Reference Figures 2 to 5 The outer shell 4 has a sliding groove at the sliding position of the folded rod 503. The snap ring 506 and snap sleeve 508 are made of wear-resistant material. Two sets of snap ring 506 and snap sleeve 508 are symmetrically arranged along the center line of the electric push rod 501.

[0060] During operation, when the electric push rod 501 drives the sector plate 502 to move up and down inside the mounting frame 1, the sector plate 502 drives the folding rod 503 to slide inside the groove opened above the outer shell 4, thereby realizing the lateral movement of the folding rod 503 and locking the wheel 3 and the connecting shaft 8. This effectively locks the wheel 3 and the connecting shaft 8, improving the stability and safety of the aircraft when parked.

[0061] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
