Description

Technical Field

[0001] This invention relates to the field of landing gear testing equipment technology, specifically to an aircraft wheel brake inertia test bench with a tire scraping device. Background Technology

[0002] Inertial table testing is a crucial criterion for evaluating the results of laboratory tests on aircraft braking control systems. It is an important means of determining performance parameters and optimizing product performance, providing assurance for product development and verification. Through inertial table testing, the performance of wheel brakes, anti-skid braking systems, and friction materials can be verified, providing vital data support for the design and improvement of aircraft braking systems.

[0003] Aircraft wheel brake inertial test benches are primarily used to simulate the actual loads, speeds, and energy conditions of an aircraft during takeoff, taxiing, and landing. By precisely controlling the moment of inertia of the inertial wheels on the test bench, the kinetic energy of the aircraft at different landing speeds is simulated, and the aircraft wheels are decelerated or stopped by brake discs or brake pads. During the inertial test bench process, due to the high-speed rotation of the wheels, some tire casings may adhere to the inertial wheels due to heat.

[0004] Currently, the tire lining that adheres to the wheel is usually removed manually by workers; however, this method of scraping off the tire lining is inefficient. Summary of the Invention

[0005] Therefore, the present invention proposes an aircraft wheel brake inertial platform with a tire scraping device, which can automatically scrape off the tire material on the inertial wheel.

[0006] The technical solution of the present invention is as follows: An aircraft wheel brake inertia platform with a tire scraping device includes a base and an inertia wheel rotatably mounted on the base, and a tire scraping device mounted on the base. The tire scraping device includes a mounting seat on the base and a tire scraping component on the mounting seat. The mounting seat and / or the tire scraping component can switch between a first position and a second position. When the mounting seat and / or the tire scraping component is in the first position, the tire scraping component abuts against the outer peripheral surface of the inertia wheel. When the mounting seat and / or the tire scraping component is in the second position, the tire scraping component disengages from the inertia wheel.

[0007] Furthermore, it also includes an inertial wheel drive device, which includes a rotary power output unit, a torque sensor, and an inertial wheel axle.

[0009] Furthermore, it also includes a landing gear drive device, which includes a second linear power output unit and a slide on the base. The slide is provided with a landing gear mounting part for mounting the landing gear. The slide can be driven by the second linear power output unit to slide so that the wheels on the landing gear abut against the outer peripheral surface of the inertia wheel, or disengage from the inertia wheel.

[0010] Furthermore, a pressure sensor is provided between the output end of the second linear power output unit and the slide table.

[0011] Furthermore, the mounting base is hinged to the base, and a first elastic element is provided between the mounting base and the base. The first elastic element applies an elastic force to the mounting base to rotate the mounting base to the second position.

[0012] Furthermore, the tire scraping component includes a fixed plate fixed to the mounting base, and a first scraper slidably disposed on the fixed plate, and a second elastic member is provided between the first scraper and the fixed plate, the second elastic member applying an elastic thrust to the first scraper to bring the first scraper closer to the inertia wheel.

[0013] Furthermore, the mounting base is provided with a drive unit and a second scraper connected to the output end of the drive unit. The second scraper can be driven by the drive unit to reciprocate along the axial direction of the inertia wheel. The two opposite sides of the second scraper are respectively provided with blades that are inclined relative to the axial direction of the inertia wheel. When the mounting base is in the first position, the two blades abut against the outer peripheral surface of the inertia wheel.

[0014] Furthermore, the drive unit includes a driven wheel, a transmission unit, a reciprocating screw, and a sliding block; the driven wheel and the reciprocating screw are rotatably mounted on the mounting base, the transmission unit is located between the driven wheel and the reciprocating screw, and the sliding block is screwed to the reciprocating screw; when the mounting base is in the first position, the driven wheel abuts against the outer circumferential surface of the inertia wheel and can be driven to rotate by the inertia wheel.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] This embodiment provides an aircraft wheel braking inertia table with a tire scraping device, hereinafter referred to as a braking inertia table. Reference Figure 1 and Figure 2 As shown, it includes a base 100 and an inertia wheel 200 rotatably mounted on the base 100. It also includes a tire scraping device 300 mounted on the base 100. The tire scraping device 300 includes a mounting seat 310 mounted on the base 100 and a tire scraping component 320 mounted on the mounting seat 310. The mounting seat 310 and / or the tire scraping component 320 can switch between a first position and a second position. When the mounting seat 310 and / or the tire scraping component 320 is in the first position, the tire scraping component 320 abuts against the outer peripheral surface of the inertia wheel 200. When the mounting seat 310 and / or the tire scraping component 320 is in the second position, the tire scraping component 320 disengages from the inertia wheel 200.

[0021] Overall, in the braking inertia platform of this embodiment, when the mounting base 310 and / or the tire scraper 320 are in the first position, the tire scraper 320 can abut against the outer peripheral surface of the inertia wheel 200 so that as the inertia wheel 200 rotates, the tire scraper 320 scrapes off the tire skin adhering to the outer peripheral surface of the inertia wheel 200; when the mounting base 310 and / or the tire scraper 320 are in the second position, the tire scraper 320 disengages from the inertia wheel 200, thereby not affecting the normal rotation of the inertia wheel 200.

[0022] refer to Figure 1 As shown, the brake inertia platform of this embodiment also includes an inertia wheel drive device 400 for driving the inertia wheel 200 to rotate. Specifically, the inertia wheel drive device 400 includes a rotational power output unit 410, a torque sensor 420, and an inertia wheel shaft 430. The rotational power output unit 410 is mounted on the base 100. One end of the torque sensor 420 is coaxially and fixedly connected to the output shaft of the rotational power output unit 410, and the other end is coaxially and fixedly connected to the inertia wheel shaft 430. The aforementioned inertia wheel 200 is fixedly sleeved on the inertia wheel shaft 430. In this embodiment, the inertia wheel drive device 400 also includes an encoder for measuring the rotational speed of the inertia wheel shaft 430.

[0023] Based on the above structure, the output shaft of the rotary power output unit 410 can drive the inertia wheel shaft 430 to rotate via the torque sensor 420, thereby driving the inertia wheel 200 to rotate. This allows the landing gear 700 to be tested by bringing the landing gear 710 into contact with the rotating inertia wheel 200. In this embodiment, the rotary power output unit 410 is a motor; in some embodiments, it can also be a hydraulic motor, etc. The torque sensor 420 and encoder can be existing products, and their structure and working principle will not be described in detail here. By setting the torque sensor 420, the torque on the inertia wheel shaft 430 can be measured, and by setting the encoder, the position and rotational speed of the inertia wheel 200 can be measured.

[0024] refer to Figure 1 and Figure 3 As shown, the braking inertia platform of this embodiment also includes a braking device 500 for braking the inertia wheel 200. Specifically, the braking device 500 includes a first linear power output unit 510, a pull rod 520, a rotating shaft 530, and brake pads 540. The pull rod 520 and brake pads 540 are respectively connected to the rotating shaft 530 and are positioned on opposite sides of the rotating shaft 530. The fixed end of the first linear power output unit 510 is hinged to the base 100, and the telescopic end is hinged to the pull rod 520. As the telescopic end extends or shortens, the rotating shaft 530 can be rotated by the pull rod 520, thereby causing the brake pads 540 to abut against or move away from the outer circumferential surface of the inertia wheel 200.

[0025] In this embodiment, the first linear power output unit 510 is a hydraulic cylinder, with its fixed end being the cylinder barrel and its telescopic end being the telescopic rod. In some embodiments, the first linear power output unit 510 may also be a pneumatic cylinder or an electric cylinder. Based on the above structure, when the telescopic rod of the hydraulic cylinder extends, it can drive the rotating shaft 530 to rotate around its own axis via the pull rod 520. The rotation of the rotating shaft 530 will drive each brake pad 540 to rotate until it abuts against the outer peripheral surface of the inertia wheel 200, thereby stopping the rotation of the inertia wheel 200 through the friction between each brake pad 540 and the inertia wheel 200. When the telescopic rod of the hydraulic cylinder shortens, it can drive the rotating shaft 530 to rotate in the opposite direction via the pull rod 520. The rotation of the rotating shaft 530 will drive each brake pad 540 away from the outer peripheral surface of the inertia wheel 200. In this state, the brake pads 540 will not affect the rotation of the inertia wheel 200.

[0026] In this embodiment, reference Figure 1 and Figure 3 As shown, a tension spring 550 is provided between the pull rod 520 and the base 100. The tension spring 550 applies a tension force to the pull rod 520, which drives the rotating shaft 530 to rotate in a direction that moves the brake pad 540 away from the outer circumferential surface of the inertia wheel 200. By providing this tension spring 550, the brake pad 540 can be more effectively disengaged from the inertia wheel 200.

[0027] refer to Figure 1 As shown, the brake inertia platform of this embodiment also includes a landing gear drive device 600 for driving the landing gear 700 to move. Specifically, the landing gear drive device 600 includes a second linear power output unit 610 and a slide 620 disposed on the base 100. The slide 620 is provided with a landing gear mounting part for mounting the landing gear 700, and the slide 620 can be driven by the second linear power output unit 610 to slide so that the wheels 710 on the landing gear 700 abut against the outer peripheral surface of the inertia wheel 200, or move away from the inertia wheel 200.

[0028] refer to Figure 1As shown, two parallel and spaced-apart guide rails 110 are fixed on the base 100, and a slider 621 adapted to the two guide rails 110 is fixed on the slide table 620. The aforementioned second linear power output unit 610 is a hydraulic cylinder, whose cylinder barrel is connected to the base 100 and whose telescopic rod is connected to the slide table 620. The telescopic rod of the hydraulic cylinder drives the slide table 620 to move along the length direction of the guide rails 110, thereby causing the landing gear 710 to contact or move away from the inertia wheel 200. In this embodiment, a pressure sensor is provided between the second linear power output unit 610 and the slide table 620. This pressure sensor is used to measure the pressure applied by the second linear power output unit 610 to the pressure sensor, that is, to measure the load applied to the landing gear 700. It should be noted that the structure of the landing gear mounting part on the slide table 620 for mounting the landing gear 700 can refer to the prior art, and will not be described in detail here.

[0029] refer to Figure 1 and Figure 2 As shown, in this embodiment, the mounting base 310 is rotatably mounted on the base 100, and a first elastic element 330 is provided between the mounting base 310 and the base 100. The first elastic element 330 applies an elastic force to the mounting base 310 to rotate it to a second position. By providing this first elastic element 330, during use, the operator pushes the mounting base 310 to rotate, causing the scraping element 320 on the mounting base 310 to abut against the outer peripheral surface of the inertia wheel 200, so that when the inertia wheel 200 rotates, the scraping element 320 scrapes off the tire residue adhering to the outer peripheral surface of the inertia wheel 200; when the operator stops pushing the mounting base 310, the mounting base 310 is driven by the first elastic element 330 to rotate until the scraping element 320 disengages from the inertia wheel 200. In this embodiment, the rotation of the mounting base 310 in the first and second positions causes the scraping component 320 to abut against the outer peripheral surface of the inertia wheel 200, or causes the scraping component 320 to disengage from the inertia wheel 200.

[0030] refer to Figure 2 As shown, the first elastic element 330 in this embodiment is a tension spring connected between the base 100 and the mounting base 310. In some embodiments, the first elastic element 330 may also be a torsion spring or the like.

[0031] In some embodiments, such as Figure 4As shown, a hydraulic drive cylinder 340 is provided between the mounting base 310 and the base 100. The fixed end of the hydraulic drive cylinder 340 is hinged to the base 100, and the telescopic end is hinged to the mounting base 310. The extension or retraction of the telescopic end of the hydraulic drive cylinder 340 can drive the mounting base 310 to rotate, causing the scraping component 320 to abut against the outer circumferential surface of the inertia wheel 200, or causing the scraping component 320 to disengage from the inertia wheel 200. By using this hydraulic cylinder to replace the operator in rotating the mounting base 310, the labor intensity of the operator can be reduced.

[0032] refer to Figure 4 As shown, the tire scraping component 320 of this embodiment includes a fixing plate 321 fixed on the mounting base 310 and a scraper slidably disposed on the fixing plate 321. For ease of description, this embodiment refers to it as a first scraper 322. A second elastic member 323 is provided between the first scraper 322 and the fixing plate 321. The second elastic member 323 applies an elastic thrust to the first scraper 322 to bring the first scraper 322 closer to the outer peripheral surface of the inertia wheel 200.

[0033] By providing the second elastic element 323 to support the first scraper 322, hard contact between the first scraper 322 and the inertia wheel 200 can be avoided, thereby reducing the risk of the first scraper 322 scratching the outer circumferential surface of the inertia wheel 200. In this embodiment, the second elastic element 323 is a spring; obviously, the second elastic element 323 can also be other elastic components.

[0034] In this embodiment, reference Figure 5 and Figure 6 As shown, the mounting base 310 is also provided with a drive unit 350 and a second scraper 360 connected to the output end of the drive unit 350. The second scraper 360 can be driven by the drive unit 350 to reciprocate along the axial direction of the inertia wheel 200. The two opposite sides of the second scraper 360 are respectively provided with blades 361 that are inclined relative to the axial direction of the inertia wheel 200. When the mounting base 310 is rotated to the first position, the two blades 361 abut against the outer peripheral surface of the inertia wheel 200.

[0035] By providing a second scraper 360 capable of reciprocating along the axial direction of the inertia wheel 200, and by tilting the blade 361 of the second scraper 360 relative to the axial direction of the inertia wheel 200, when the second scraper 360 contacts the tire skin on the outer circumferential surface of the inertia wheel 200, it can obliquely enter between the tire skin and the inertia wheel 200 from the edge corner. This allows the blade 361 to insert between the tire skin and the inertia wheel 200 with relatively small force, meaning the second scraper 360 can effectively scrape off the tire skin on the outer circumferential surface of the inertia wheel 200. Furthermore, by providing blades 361 on both opposite sides of the second scraper 360, the tire skin on the outer circumferential surface of the inertia wheel 200 can be scraped off in both directions when the second scraper 360 moves in both directions.

[0036] In terms of specific structure, refer to Figure 5 and Figure 6 As shown, the drive unit 350 includes a driven wheel 351, a transmission unit, a reciprocating screw 352, and a sliding block 353. The driven wheel 351 and the reciprocating screw 352 are rotatably mounted on the mounting base 310. The transmission unit is located between the driven wheel 351 and the reciprocating screw 352. The sliding block 353 is screwed to the reciprocating screw 352. When the mounting base 310 rotates to the first position, the driven wheel 351 abuts against the outer circumferential surface of the inertia wheel 200 and can be driven to rotate by the inertia wheel 200. Through the transmission unit, the rotation of the driven wheel 351 drives the reciprocating screw 352 to rotate, and causes the sliding block 353 to reciprocate along the axial direction of the reciprocating screw 352. The second scraper 360 is mounted on the sliding block 353.

[0037] The aforementioned transmission unit includes a first synchronous pulley coaxially and fixedly connected to the driven pulley 351, a second synchronous pulley coaxially and fixedly connected to the reciprocating lead screw 352, and a synchronous belt disposed between the second synchronous pulley and the first synchronous pulley. In some embodiments, the transmission unit may further include a first gear coaxially and fixedly connected to the driven pulley 351, and a second gear coaxially and fixedly connected to the reciprocating lead screw 352, wherein the second gear meshes with the first gear.

[0038] Based on the above structure, when the mounting base 310 is in the first position, the rotation of the inertia wheel 200 drives the driven wheel 351 to rotate through the friction between the driven wheel 351 and the inertia wheel 200. The rotation of the driven wheel 351 drives the reciprocating screw 352 to rotate through the transmission of the first synchronous wheel and the second synchronous wheel. The sliding block 353, which is screwed to the reciprocating screw 352, drives the second scraper 360 on the sliding block 353 to move back and forth along the axial direction of the reciprocating screw 352 under the guidance of the guide rod, so that the second scraper 360 scrapes the tire skin on the outer peripheral surface of the inertia wheel 200.

[0039] In some embodiments, a screw is rotatably provided on the mounting base 310. Along the axial direction of the screw, left-handed and right-handed external threads are spaced apart on the outer periphery of the screw, and nut seats are screwed onto the left-handed and right-handed external threads respectively. The scraping component 320 includes two scraping plates respectively disposed on the two nut seats. As the screw rotates, the two scraping plates can approach each other and abut against the outer peripheral surface of the inertia wheel 200, or move away from each other and to both sides of the inertia wheel 200, away from its outer peripheral surface. In this embodiment, the mounting base 310 is fixed, and the scraping component 320 can switch between a first position and a second position, causing the scraping component 320 to abut against the outer peripheral surface of the inertia wheel 200, or causing the scraping component 320 to disengage from the inertia wheel 200.

[0040] Based on the above overall structure, the overall working process of the braking inertial platform in this embodiment is as follows: The motor of the inertial wheel drive device 400 rotates, driving the inertial wheel 200 to rotate, and the speed of the inertial wheel 200 is measured by the encoder. The speed of the inertial wheel 200 is used to simulate the translational speed of the aircraft landing gear 700 when it lands. The hydraulic cylinder of the landing gear drive unit 600 is activated, pushing the landing gear 700 to contact the inertia wheel 200, so that the inertia wheel 200 and the landing gear 700's wheels 710 rotate synchronously to simulate the speed of the landing gear 700 at the moment of landing. The hydraulic cylinder continuously applies loading force to simulate the process of the aircraft's weight being continuously loaded onto the runway during the landing process. The moment the landing gear 700 wheel 710 contacts the inertia wheel 200, the braking device 500 is activated. The hydraulic cylinder of the braking device 500 is activated, which drives the brake pad 540 to brake the inertia wheel 200, simulating the runway providing the wheel 710 with corresponding reverse rotation after the aircraft lands, until the wheel 710 stops moving. During the above process, the wheel 710 rotates at high speed, and tire skin will stick to the inertia wheel 200. The tire skin on the inertia wheel 200 is scraped off by the tire skin scraping device 300.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
