Caliper drag torque testing device

Abstract

This utility model discloses a caliper drag torque testing device, including a base; a drive component disposed on the base, with a torque sensor connected to the output end of the drive component; a rotating component connected to the torque sensor via a universal joint; and a testing mechanism including an adjusting component and a caliper. The caliper is disposed on the adjusting component, which is used to adjust the caliper's proximity to or distance from the rotating component and to adjust the angle of the caliper on the rotating component. The caliper is connected to a driving device. The drive component drives the rotating component to rotate to simulate the driving process of a wheel. After the adjusting component drives the caliper to approach the rotating component, the driving device drives the caliper to clamp and release the rotating component. The torque of the rotating component at this time is tested by the torque sensor and compared with the torque when it is initially unclamped, thereby calculating the drag torque of the caliper. At the same time, by adjusting the drive component, the drag torque at different speeds can be tested, making the testing process more consistent with the actual driving process of a vehicle.

[0024] Reference Figures 1 to 3 The technical solution of this utility model relates to a caliper 400 drag torque testing device, including: a base 100; a drive member 200, disposed on the base 100, the output end of the drive member 200 being connected to a torque sensor 210; a rotating member 300, connected to the torque sensor 210 via a universal joint 220; and a testing mechanism, including an adjusting member and a caliper 400, the caliper 400 being disposed on the adjusting member, the adjusting member being used to adjust the caliper 400 to move closer to or further away from the rotating member 300, and to adjust the angle of the caliper 400 on the rotating member 300, the caliper 400 being connected to a drive device.

[0025] The drag torque testing device for the caliper 400 described above has at least the following beneficial effects: the driving component 200 drives the rotating component 300 to rotate, simulating the driving process of the wheel. After the caliper 400 is driven to approach the rotating component 300 by the adjusting component, the driving device drives the caliper 400 to clamp and release the rotating component 300 to simulate the braking process. After multiple clamping and releasing cycles, the torque of the rotating component 300 at this time is tested by the torque sensor 210 and compared with the torque when it is not clamped initially, thereby calculating the drag torque of the caliper 400. At the same time, by adjusting the driving component 200, the drag torque at different speeds can be tested, making the testing process more consistent with the actual driving process of the vehicle.

[0026] According to some embodiments of this utility model, a support frame 110 is provided on the base 100, and a first rotating shaft is movably arranged on the support frame 110. The first rotating shaft is connected to the output end of the drive component 200 through a synchronous belt mechanism 120. The torque sensor 210 is connected to the first rotating shaft through a universal joint 220. A second rotating shaft is provided on the support frame 110. One end of the second rotating shaft is connected to the torque sensor 210 through a universal joint 220, and the other end is connected to the rotating component 300. The synchronous belt mechanism 120 allows the drive component 200 to be located on one side of the base 100, reducing the length of the shaft system to reduce errors. At the same time, it can shorten the overall length of the testing device, making its structure more compact.

[0027] According to some embodiments of the present invention, the adjusting component includes a displacement adjusting component and an angle adjusting component. The displacement adjusting component is disposed on one side of the base 100, and the angle adjusting component is disposed above the displacement adjusting component. The caliper 400 is disposed on the angle adjusting component. The displacement adjusting component is used to drive the angle adjusting component and the caliper 400 to move closer to or away from the rotating component 300. The angle adjusting component is used to adjust the installation angle of the caliper 400 relative to the rotating component 300.

[0028] According to some embodiments of this utility model, the displacement adjustment assembly includes: a first base plate 500, disposed on one side of the base 100; a slide rail 510, disposed on the first base plate 500; a slider 520, slidably connected to the slide rail 510, and an angle adjustment assembly disposed on the slider 520; a first lead screw mechanism 530, disposed on the first base plate 500, the output end of the first lead screw mechanism 530 being connected to a third rotating shaft, the slider 520 being threadedly connected to the third rotating shaft, and the first lead screw mechanism 530 being used to drive the third rotating shaft. The rotating shaft rotates to drive the slider 520 to move closer to or away from the rotating member 300; the first adjusting member 540 is connected to the first lead screw mechanism 530, and the first adjusting member 540 drives the first lead screw mechanism 530 to move, so that the third rotating shaft rotates. Since there is a threaded connection between the third rotating shaft and the slider 520, a new lead screw structure is formed between the third rotating shaft and the slider 520, so that the slider 520 can move along the slide rail 510, thereby allowing the angle adjusting component and the caliper to move closer to or away from the rotating member 300.

[0029] According to some embodiments of this utility model, the angle adjustment assembly includes: a second base plate 600 disposed on the slider 520; a second lead screw mechanism 610 disposed on the second base plate 600, the output end of the second lead screw mechanism 610 being connected to a fourth rotating shaft; a mounting plate 620 connected to the fourth rotating shaft, the caliper 400 disposed on the mounting plate 620, the second lead screw mechanism 610 being used to drive the fourth rotating shaft to rotate, thereby driving the mounting plate 620 to rotate; and a second adjusting member 630 connected to the second lead screw mechanism 610, the second adjusting member 630 driving the second lead screw mechanism 610 to move, thereby driving the fourth rotating shaft to rotate, the fourth rotating shaft driving the mounting plate 620 to rotate, thereby adjusting the installation position of the caliper 400 relative to the rotating member 300, to simulate the different installation positions of calipers on different vehicles during actual installation, making the test more consistent with the actual situation and the test results more accurate.

[0030] According to some embodiments of the present invention, the second base plate 600 is further provided with a locking block 640 and a locking handle 650. The locking block 640 is provided with a through hole and an opening groove connecting the through hole. The locking handle 650 is located on the side of the opening groove. One end of the third rotating shaft is located in the through hole. By tightening the locking handle 650, the opening groove is squeezed, thereby fixing the third rotating shaft in the through hole and preventing it from rotating under the action of friction.

[0031] According to some embodiments of the present invention, the output end of the second lead screw mechanism 610 is also provided with an angle scale 660, and the installation angle of the caliper 400 is determined by the angle scale 660.

[0032] According to some embodiments of the present invention, both the first adjusting member 540 and the second adjusting member 630 are configured as adjusting handwheels or motors.

[0033] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.
