The product of the friction force f and its lever arm is the braking torque M.

[0045] Embodiment 1: See also Figure 1 — Fig.12, a brake torque testing device, the device comprises a rotating body 1 and a base 2; the rotating body 1 comprises an arc panel 11 and a support frame 12, the top of the arc panel 11 is connected to the bottom of the support frame 12, the support frame 12 is triangular, the middle part of the support frame 12 is connected to one end of a connecting handle 13, and the other end of the connecting handle 13 is movably connected to one end of a linear connecting rod 14; the top of the support frame 12 is a rotating hole 15, and the middle part of a rotating shaft 3 is inserted into the rotating hole 15; the two ends of the rotating shaft 3 are movably connected to the middle part of a fixed seat 21 at the top of the base 2; the base 2 comprises a vertical support plate 22, a horizontal support plate 23 and a positioning plate 24, one end of the vertical support plate 22 is connected to the bottom of the fixed seat 21, the bottom of the vertical support plate 22 is vertically connected to one end of the horizontal support plate 23, and the top of the other end of the horizontal support plate 23 is connected to the bottom of the positioning plate 24.

[0046] When in use, first push the linear connecting rod 14 to test the rotation effect of the support frame 12 to ensure that the rotation of the support frame 12 is flexible and without jamming; then connect and fix the push-pull force sensor 82 to one end of the linear connecting rod 14 outside the base 2, and then start the test process of the thrust ft without the action of the brake: first push the push-pull force sensor 82 at a uniform speed in the direction of the support frame 12, and then the push-pull force sensor 82 drives the connecting handle 13 to move in the direction of the support frame 12, and then the connecting handle 13 drives the middle part of the support frame 12 to move away from the push-pull force sensor 82. Because the top of the support frame 12 is inserted with a rotating shaft 3, the support frame 12 moves along The rotating shaft 3 rotates; repeat the above test process at least three times, and then take the average value of the thrust ft without the brake; then release the push-pull force sensor 82, and the support frame 12 returns to the initial position under the action of gravity, and then connect and fix the brake 8 with the positioning plate 24, so that the position between the brake 8 and the arc panel 11 is appropriate, and then adjust the piston in the brake 8 to connect the brake 8 with the arc panel 11; then start the maximum push-pull force Ft test process: first push the push-pull force sensor 82 at a uniform speed in the direction of the support frame 12, and then the push-pull force sensor 82 drives the connecting handle 13 to move in the direction of the support frame 12, and then The connecting handle 13 drives the middle part of the support frame 12 to move away from the push-pull force sensor 82. Since the rotating shaft 3 is inserted into the top of the support frame 12, the support frame 12 rotates along the rotating shaft 3, that is, the support frame 12 has a clockwise rotation trend, so the arc panel 11 has a clockwise rotation trend, but because the arc panel 11 is connected to the brake 8, a huge friction force is generated between the brake 8 and the arc panel 11, so the arc panel 11 stops moving; repeat the above test process at least three times, and then take the average value of the maximum push-pull force Ft; then perform a force analysis on the above measurement process, the maximum push-pull force Ft is horizontal to the left, and the connecting handle 13 is parallel to the horizontal line. The angle between them is angle α, and the direction of the friction force f on the arc panel 11 is downward along the angle α, so the horizontal right component of the friction force f is fcosα, and the reaction force of the thrust ft without the action of the brake is the same as the thrust ft without the action of the brake, but in the opposite direction. Therefore, according to Newton's third law, the formula is obtained, fcosα=Ft-ft, and then the magnitude of the friction force f is obtained, and then the vertical distance s from the connecting handle 13 to the rotating axis 3 is measured, then the braking torque M=fs; the vertical support plate 22 provides support for the fixed seat 21, and the horizontal support plate 23 provides support for the vertical support plate 22 and the positioning plate 24.
