Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-4 The utility model provides a vehicle brake drag torque detection device, including a base plate 1, a lifting mechanism 2 and a mounting plate 3 are arranged on the upper end of the base plate 1, the base plate 1 is connected to the mounting plate 3 through the lifting mechanism 2, an adjustment mechanism 6 and a drag torque detection mechanism 7 are arranged on the upper end of the mounting plate 3, and the mounting plate 3 is connected to the drag torque detection mechanism 7 through the adjustment mechanism 6; a universal wheel 4 is fixedly connected to the lower end of the base plate 1, and four universal wheels 4 are arranged and evenly distributed at the four corners of the lower end of the base plate 1.

[0026] Specifically, the whole vehicle is lifted by a lifting machine so that the wheels are away from the ground, and then the mounting plate 3 is pushed. At this time, the device can be conveniently transferred to the required place under the action of the universal wheel 4. Then, according to the needs, the adjustment mechanism 6 is used to adjust the distance between the two drag torque detection mechanisms 7 to facilitate the drag torque detection of the brakes on the two wheels of different widths. After the adjustment is completed, the lifting mechanism 2 is used to drive the drag torque detection mechanism 7 to move upward, so that the detection end of the drag torque detection mechanism 7 contacts the wheel, which makes it convenient to detect the drag torque of the brake on the wheel, thereby improving the practicability of the device.

[0027] The lifting mechanism 2 includes a first motor 201, a first screw rod 202, a first slider 604203 and a connecting tube 204. The lower end of the base plate 1 is fixedly connected to the first motor 201, the output end of the first motor 201 passes through the base plate 1 and is rotatably connected to the base plate 1, the output end of the first motor 201 is fixedly connected to the first screw rod 202, the circumferential surface of the first screw rod 202 is threadedly connected to the first slider 604203, the upper end of the first slider 604203 is fixedly connected to the connecting tube 204, and the upper end of the connecting tube 204 is fixedly connected to the mounting plate 3. When working, the first motor 201 works, and at this time, the slider 604 can be driven to move under the action of the first screw rod 202, and then the mounting plate 3 can be driven to move under the action of the connecting tube 204. With the movement of the mounting plate 3, the drag torque detection mechanism 7 can be driven to move up or down. When the drag torque detection mechanism 7 moves up, it is convenient to perform drag torque detection on the brake on the wheel.

[0028] The four corners of the upper end of the base plate 1 are fixedly connected with guide cylinders 5, and guide rods 8 are slidably connected inside the guide cylinders 5. The guide rods 8 are fixedly connected to the mounting plate 3. When working, by setting the guide cylinders 5 and the guide rods 8, the movement of the mounting plate 3 can be limited under the action of the guide cylinders 5 and the guide rods 8, so that the mounting plate 3 can move up and down smoothly.

[0029] A first retaining ring 9 is fixedly connected to the upper end of the guide cylinder 5, and the first retaining ring 9 is slidably connected to the guide rod 8. A second retaining ring 10 is fixedly connected to the circumferential surface of the lower end of the guide rod 8, and the second retaining ring 10 is slidably connected to the guide cylinder 5.

When working, by rotating the handle 603, the slider 604 can be driven to slide on the slide rail 605 under the action of the second screw rod 602, thereby changing the distance between the two drag torque detection mechanisms 7, which is beneficial for drag torque detection of brakes on two wheels of different widths.

[0031] The drag torque detection mechanism 7 includes a bearing seat 701, a second motor 702, a torque sensor 703 and a transmission wheel 704. The upper end of the slider 604 is fixedly connected to the bearing seat 701, and the side end of the bearing seat 701 is fixedly connected to the second motor 702. The output end of the second motor 702 passes through the bearing seat 701 and is rotatably connected to the bearing seat 701. The output end of the second motor 702 is fixedly connected to the torque sensor 703, and the end of the torque sensor 703 away from the second motor 702 is fixedly connected to the transmission wheel 704. When working, after the transmission wheel 704 contacts the wheel, the second motor 702 is started, and then the torque sensor 703 can be driven to rotate under the action of the second motor 702, and then the transmission wheel 704 is driven to rotate.
