[0002] The brake pad, also known as the brake pad, is a component installed in the automobile braking system for automobile braking. The automobile wheels are installed on the axle, and the brake disc is installed on the axle. The brake system can stop the rotation of the axle by controlling the contact between the brake pad and the brake disc, thereby achieving the effect of braking the vehicle.

[0003] After the completion of the production of the brake pad, the performance of the brake pad needs to be detected. The existing brake pad detection equipment includes a base plate, an extension piece, a mounting seat and a plurality of sensors. The extension piece can be provided as a pneumatic cylinder or a hydraulic cylinder. One end of the extension piece is connected to the base plate, and the other end is connected to the mounting seat. A recess for mounting the brake pad is formed on one side of the mounting seat close to the base plate. The plurality of sensors are mounted on the mounting seat. The extension piece drives the mounting seat to move, thereby enabling the brake pad to move. By arranging the rotating brake disc between the mounting seat and the base plate, the brake pad can be in contact with the brake disc. The sensor can detect the friction coefficient of the brake pad under different temperatures and pressures, thereby measuring the data of the brake pad during braking.

[0004] The related technical solutions in the above have the following defects: during the detection of the brake pad, the brake pad needs to be controlled to contact the rotating brake disc and the stationary brake disc respectively, so as to measure the performance of the brake pad during the braking of the moving vehicle and the pulling down of the hand brake of the stationary vehicle respectively. The brake pad detection process needs to install the brake pad on different detection machines respectively, so that the detection efficiency is low. SUMMARY

[0005] In order to be able to detect the performance of the brake pad in different working states in the same equipment, the present application provides a brake pad braking detection device.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] The present application discloses a brake pad brake detection device, referring to Figure 1 and Figure 2 The device comprises a frame 1, a brake pad simulator 2, and a disc 3. Disc 3 is rotatably connected to frame 1, with the disc 3 and frame 1 forming a horizontal axis. Brake pad simulator 2 is slidably connected to frame 1 and is used to mount the brake pad to be tested. Brake pad simulator 2 can slide to the upper side of disc 3, allowing the brake pad to be tested to move to the side of disc 3. At this time, brake pad simulator 2 drives the brake pad to abut against the rotating disc 3, thereby simulating the use of the brake pad. Brake pad simulator 2 then detects the braking performance data of the brake pad.

[0031] When brake pads are installed in a car, a brake disc is mounted on the drive shaft. During normal driving, a gap of approximately 0.1-0.3 mm exists between the pads and discs, minimizing the chance of debris entering the friction surface between them. When the car brakes, the pads and discs fit tightly together, generating frictional heat. When the car stops and the driver applies the handbrake, the pads and discs maintain contact, preventing the car from rolling away and improving safety.

[0032] Reference Figure 1 The brake pad simulator 2 is detachably connected to a wheel simulation card 4. When the brake pad simulator 2 slides to the side away from the disc 3, the user inserts the wheel simulation card 4 into the brake pad simulator 2 so that the brake pad can squeeze the wheel simulation card 4. At this time, the brake pad simulator 2 detects the performance data of the brake pad when the car stops and the handbrake is pulled.

[0033] Reference Figure 3 The frame 1 is provided with a guide rail 11, which is horizontally arranged on the top surface of the frame 1 and is located on one side of the disc 3. The brake pad simulator 2 includes a base plate 21, a mounting seat 22, a plurality of sensors 23 and a telescopic member 24. The base plate 21 is slidably connected to the guide rail 11 and is parallel to the disc 3. The mounting seat 22 is fixed to the base plate 21, and the sensor 23 is mounted on the mounting seat 22. The telescopic member 24 can be a hydraulic cylinder or a pneumatic cylinder. One end of the telescopic member 24 is fixed to the mounting seat 22 and the other end is fixed to the frame 1. The telescopic member 24 is perpendicular to the base plate 21. There is a gap between the mounting seat 22 and the base plate 21. When the base plate 21 slides onto the disc 3, the disc 3 is located between the mounting seat 22 and the base plate 21. When the user installs the brake pad on the mounting seat 22, the brake pad can protrude from the surface of the mounting seat 22. By controlling the telescopic member 24 to extend or contract, the user can move the brake pad along the axis of the disc 3, thereby allowing the brake pad to abut against the rotating disc 3. When the brake pad abuts against the disc 3 , it can be used to simulate the working state of the brake pad. The sensor 23 can detect the brake pad's engagement gap, working gap, slow release time and other data.

The positioning member 12 is provided with a plurality of positioning holes 121, the positioning holes 121 are vertically provided, the plug plate 211 is provided with a plurality of through holes, the through holes are one-to-one corresponding to the positioning holes 121 in position and size. The positioning member 12 is detachably connected with a latch 122, one latch 122 is inserted into each positioning hole 121, the plug plate 211 can slide and be inserted into the positioning member 12, the latch 122 is inserted into the positioning member 12 and the plug plate 211, which can fix the brake pad simulation machine 2. When the brake pad abuts against the disc 3, the brake pad simulation machine 2 is fixed on the rack 1 to keep the position stable.

[0035] Referring to Figure 4 and Figure 5 , the wheel simulation card 4 comprises a card plate 41 and a handle 42, the card plate 41 is used for being inserted between the brake pad and the base plate 21, and the handle 42 is fixed on one side of the card plate 41. When the user slides the brake pad simulation machine 2 to the edge of the rack 1, the card plate 41 is inserted into the brake pad simulation machine 2, so that the brake pad can contact and press the card plate 41, and then the sensor 23 can detect the performance data such as strength, stiffness and deformation of the brake pad.

[0036] Referring to Figure 4 and Figure 5 , the card plate 41 is provided with a hollow groove 411, which is used for reducing the weight of the card plate 41. The card plate 41 is provided with an inclined surface 412 away from the handle 42, which facilitates the user to insert the card plate 41 into the brake pad simulation machine 2.

[0037] Referring to Figure 4 and Figure 5 , one side of the card plate 41 is fixed with a limiting block 43, which is used for abutting against the side surface of the base plate 21. The base plate 21 is fixed with a guide block 212, which is inclined upward, when the card plate 41 is inserted into the brake pad simulation machine 2, the limiting block 43 abuts against the guide block 212, so that the card plate 41 is inclined upward and inserted into the brake pad simulation machine 2, and then the brake pad installed in the brake pad simulation machine 2 is tangent to the disc 3, so that the contact area between the brake pad and the disc 3 is larger. The base plate 21 is provided with a pad 213, which is fixed on the upper side of the guide block 212, when the card plate 41 is inserted into the brake pad simulation machine 2, the pad 213 and the brake pad are respectively arranged on both sides of the card plate 41, when the brake pad presses on the card plate 41, the pad 213 provides support for the card plate 41.

[0038] Referring to Figure 4 and Figure 5A clip 44 is fixed to the clip plate 41. The clip 44 is arranged perpendicular to the clip plate 41 and is located on the side of the clip plate 41 connected to the handle 42. When the clip plate 41 is inserted into the brake pad simulator 2, the clip 44 is locked on the side wall of the base plate 21. The clip 44 has a positioning effect, making it easier for the user to install the wheel simulation card 4 into the brake pad simulator 2.

[0039] The implementation principle of the embodiment of the present application is: by slidingly connecting the brake pad simulator 2 on the frame 1, the brake pad simulator 2 can slide to the disc 3, and the disc 3 simulates the car brake disc by rotating. By making the brake pad contact with the disc 3, the sensor 23 on the mounting seat 22 can detect the temperature rise, heat dissipation and other braking data of the brake pad.
