Problems solved by technology

[0004] At present, the domestic measurement of the braking torque of the aircraft braking device is carried out on a large-scale brake inertia test bench before leaving the factory, and the measurement of the braking torque of the wheel installed on the landing gear is usually done by manually holding the ruler to measure the force arm. Then carry out the follow-up torque conversion. S

Example Embodiment

[0027] Example 1:

[0028] A wheel brake torque test device of this embodiment, such as Figure 1-Figure 4 As shown, it includes a left splint 1 and a right splint 2 arranged on the left and right. The left splint 1 and the right splint 2 are connected by a moving assembly 3, and the moving assembly 3 is used to drive the left splint 1 and the right splint 2 to approach each other or Far away from each other; parallel to one side of the moving component 3 is provided with a ruler 4 that moves in the opposite direction to the moving component 3 and is used to detect the distance between the left splint 1 and the right splint 2, and a test component 5 is slidably arranged on the ruler 4, The test assembly 5 is provided with a test port for testing torque.

[0029] The left splint 1 and the right splint 2 are respectively arranged on the left and right sides of the wheel. The left splint 1 and the right splint 2 approach each other under the driving of the moving assembly 3 until the...

Example Embodiment

[0030] Example 2:

[0031] This embodiment is further optimized on the basis of embodiment 1, such as figure 1 As shown, the moving assembly 3 includes a screw rod 31, a coaxially arranged left insert 32 and a right insert 33. The left insert 32 is arranged on the top of the left splint 1, and the right insert 33 is arranged on the right. On the top of the splint 2, the left end of the screw rod 31 is rotatably clamped with the left insert 32, and the right end of the screw rod 31 is threadedly connected with the right insert 33.

[0032] The tops of the left splint 1 and the right splint 2 are coaxially provided with a left mounting hole and a right. The left insert 32 is installed in the left mounting hole on the top of the left splint 1, and the right insert 33 is installed on the top of the right splint 2. In the hole, the left end of the left insert 32 corresponds to the left end of the left mounting hole with a left flange, and the left flange and the left end of the left mou...

Example Embodiment

[0037] Example 3:

[0038] This embodiment is further optimized on the basis of the above-mentioned embodiment 1 or 2, in order to avoid the difference between the cross-sectional area of ​​the screw 31 and the cross-sectional area of ​​the ruler 4 being too large, resulting in the relative linear movement of the screw 31 and the ruler 4 The unbalanced moment, therefore, the cross-sectional area of ​​the screw rod 31 is equal to the cross-sectional area of ​​the scale 4, and the unbalanced moment generated when the screw rod 31 and the scale 4 move relatively linearly is minimized.

[0039] Further, the left side of the midpoint of the screw rod 31 is an optical axis section, the right side of the midpoint of the screw rod 31 is a threaded section, and the optical axis section of the screw rod 31 is rotatably connected with the installation light hole inside the left insert 32, The threaded end of the screw rod 31 is threadedly connected with the mounting threaded hole inside the r...

Abstract

The invention discloses an airplane wheel brake torque testing device which comprises a left clamping plate and a right clamping plate which are arranged on the left and right, the left clamping plateand the right clamping plate are connected through a moving assembly, and the moving assembly is used for driving the left clamping plate and the right clamping plate to get close to each other or get away from each other. One side of the moving assembly is provided with a ruler which moves in the reverse direction of the moving assembly and is used for detecting the distance between the left clamping plate and the right clamping plate, the ruler is slidably provided with a testing assembly, and the testing assembly is provided with a testing opening used for testing torque. The device has the beneficial effect of conveniently and accurately measuring the brake torque of the wheel mounted on the undercarriage.

Description

technical field [0001] The invention belongs to the technical field of wheel torque testing devices, and in particular relates to a wheel braking torque testing device. Background technique [0002] Braking torque, also known as braking torque, is the torque generated by the brake device to prevent the wheel from rolling when the wheel brakes, and is opposite to the direction of the combined torque. It is one of the key parameters in the design of the brake wheel. It is not only the basis for determining the structural parameters of the brake device, but also directly affects the structural strength of the landing gear, tires, and hubs. The main parameters of running time, energy absorption, etc. [0003] With the development of aircraft, the speed and weight of the aircraft are gradually increasing during take-off and landing, and the safety problems during take-off and landing are becoming more and more prominent. The requirements for the performance and reliability of th...
