Description

Technical Field

[0001] This utility model relates to the technical field of brake pad testing equipment, and in particular to a brake pad testing equipment. Background Technology

[0002] With the rapid development of the automotive industry, brake pads, as a core component related to driving safety, have become paramount in terms of quality testing. In the past, traditional brake pad testing equipment revealed a series of problems in practical applications. Regarding the installation and removal of brake discs, traditional equipment was complex in structure and cumbersome in operation. Workers often needed to use multiple tools and spend a significant amount of time and energy to complete the installation and removal of brake discs. Furthermore, frequent and complex operations could easily lead to worker fatigue, increasing the probability of operational errors, which could damage the equipment or affect the accuracy of the test results. At the same time, traditional testing equipment suffered from a serious lack of testing flexibility. Most could only test specific models and specifications of brake pads and brake discs, making it difficult to adapt to diverse market demands and failing to comprehensively and realistically simulate the performance of brake pads under different working conditions, thus significantly reducing the reference value of the test results. In addition, the intense friction between the brake disc and brake pads during testing generated a large amount of heat. Traditional testing equipment lacked effective cooling measures, causing the brake disc temperature to rise continuously. High temperatures not only altered the physical properties of the brake disc and brake pads, leading to increased testing errors and affecting the accuracy of the test results, but also posed a challenge. Therefore, we propose a new brake pad testing equipment to address this problem. Utility Model Content

A clamping plate is fixedly installed on the top of each set of fixing rods on the same side. A brake pad is provided between the two sets of clamping plates. A hydraulic cylinder is fixedly installed on one side of the bracket. The output end of the hydraulic cylinder is connected to the hydraulic channel.

[0006] Preferably, a second workbench is provided on one side of the brake disc, and a cooling assembly is provided on the top of the second workbench. The cooling assembly includes a water tank, which is fixedly installed on the top of the second workbench. A water inlet pipe is fixedly installed on the top of the water tank. A long pipe is fixedly installed inside the water tank, extending to the top of the water tank. A pump body is fixedly installed on the top of the long pipe, and a connecting pipe is fixedly installed on the top of the pump body. A spray head is fixedly installed at one end of the connecting pipe.

[0007] Preferably, the first inclined block and the two sets of second inclined blocks are slidably installed inside the placement groove, and the outer sides of the two sets of insertion rods are provided with springs, and the two ends of the two sets of springs are respectively fixedly connected to the corresponding second inclined block and the inner wall of one side of the placement groove.

[0008] Preferably, a pull rod is fixedly installed on one side of the inclined block, the pull rod slides through to one side of the connector, a pull plate is fixedly installed at one end of the pull rod, and a spring is provided on the outside of the pull rod. The two ends of the spring are fixedly connected to the inclined block and the inner wall of one side of the placement groove, respectively.

[0009] Preferably, rectangular grooves are provided inside both sides of the bracket, guide rods are fixedly installed inside both sets of rectangular grooves, short plates are slidably installed on the outer sides of both sets of guide rods, the short plates are fixedly connected to corresponding piston blocks, and springs are provided on the outer sides of both sets of guide rods. The two ends of the springs are fixedly connected to the corresponding short plates and the inner wall of one side of the rectangular grooves, respectively.

[0010] Preferably, the two sets of bidirectional lead screws are rotatably installed inside the corresponding housings, and one end of each set of bidirectional lead screws rotatably passes through to one side of the corresponding housing. A rocker arm is fixedly installed at one end of each set of bidirectional lead screws. Two sets of limiting rods are slidably installed inside the two sets of threaded plates on the same side. The two ends of the two sets of limiting rods on the same side are fixedly connected to the inner walls of the two sides of the corresponding housing. Two sets of sliding grooves are opened on one side of each set of housings. The four sets of fixed rods on the same side are slidably installed inside the corresponding two sets of sliding grooves.

[0011] In this invention, a brake pad testing device includes a disassembly assembly and a cooling assembly. Pulling a pull plate causes a pull rod and a first inclined block to move. As the first inclined block moves, it compresses a first spring. Simultaneously, the reset of two sets of second springs ensures that the inclined surfaces of the two sets of second inclined blocks remain in contact with the inclined surface of the first inclined block. Under the reset action of the first spring, the first inclined block compresses the two sets of second inclined blocks. This, in turn, compresses the second spring, causing a rod to move and insert into the brake disc, driving the pump to draw coolant from the water tank and deliver it to the spray head through a connecting pipe. The spray head evenly sprays coolant onto the rotating brake disc. The coolant absorbs the heat from the brake disc. This simple structure is easy to operate, allowing for quick installation and removal of the brake disc. It also allows for the replacement of different models and specifications of brake pads, enabling simulation testing with different types of brake discs to more comprehensively and realistically evaluate brake pad performance. This provides greater flexibility to the testing work. Furthermore, the cooling components ensure that the brake disc is always within a suitable temperature range, avoiding testing errors caused by high temperatures, ensuring the accuracy of test results, extending the service life of the equipment, and maintaining stable operation.

[0012] This invention relates to a brake pad testing device comprising a hydraulic cylinder, a spring, a guide rod, a short plate, a piston block, and a clamping assembly. Rotating the rocker arm drives a bidirectional lead screw. Since the outer thread of the bidirectional lead screw is connected to two sets of threaded plates, the rotation of the lead screw causes these two sets of threaded plates to move relative to each other along the axial direction of the lead screw. As the threaded plates move, the clamping plates also move, clamping the brake pads between the two sets of clamping plates, ensuring accurate clamping. When the piston block moves under the push of hydraulic oil, the short plate moves along with the piston block and slides on the guide rod. The guide rod ensures the stability of the piston block's movement direction. The spring acts as a buffer and reset mechanism during the piston block's movement, clamping and fixing brake pads of different specifications, ensuring the positional stability of the brake pads during testing and avoiding testing errors caused by loose clamping. The spring's own elasticity allows for rapid and smooth reset of the piston block and related components, preventing impact from pressure changes on the equipment, effectively extending the equipment's service life, ensuring continuous and stable operation, and preparing it for the next test at any time.

The cooling assembly 9 includes a water tank 901, which is fixedly installed on the top of the workbench 2. A water inlet pipe 902 is fixedly installed on the top of the water tank 901. A long pipe is fixedly installed inside the water tank 901, extending to the top of the water tank 901. A pump body 903 is fixedly installed on the top of the long pipe. A connecting pipe 904 is fixedly installed on the top of the pump body 903. A spray head 905 is fixedly installed at one end of the connecting pipe 904 to facilitate cooling of the brake disc 3. An inclined block 801 and two sets of inclined blocks 802 are slidably installed inside the placement groove. Springs 807 are provided on the outer side of the two sets of insert rods 803. The two ends of the two sets of springs 807 are fixedly connected to the corresponding inclined block 802 and the inner wall of one side of the placement groove, respectively, so that the inclined block 802 can drive the insert rod 803 to quickly reset, facilitating the quick installation of the brake disc 3.

[0024] In this embodiment, a pull rod 804 is fixedly installed on one side of the inclined block 801. The pull rod 804 slides through to one side of the connector. A pull plate 805 is fixedly installed at one end of the pull rod 804. A spring 806 is provided on the outside of the pull rod 804. The two ends of the spring 806 are fixedly connected to the inclined block 801 and the inner wall of one side of the placement groove, respectively, to facilitate quick installation and removal of the brake disc 3. Rectangular grooves are opened inside both sides of the bracket 4. Guide rods 15 are fixedly installed inside both sets of rectangular grooves. Short plates 13 are slidably installed on the outside of both sets of guide rods 15. The two sets of short plates 13 are fixedly connected to the corresponding piston blocks 5. Springs 14 are provided on the outside of both sets of guide rods 15. The two ends of the two sets of springs 14 are connected to the corresponding short plates 13 and the rectangular grooves, respectively. One side of the inner wall is fixedly connected to facilitate the quick reset of the fixed brake pad 6 for the next test. Two sets of bidirectional lead screws 701 are rotatably installed inside the corresponding housings. One end of each set of bidirectional lead screws 701 is rotatably inserted through one side of the corresponding housing. One end of each set of bidirectional lead screws 701 is fixedly installed with a rocker arm 706. Two sets of limiting rods 705 are slidably installed inside the two sets of threaded plates 702 on the same side. The two ends of the two sets of limiting rods 705 on the same side are fixedly connected to the inner walls of the corresponding housings on both sides. Two sets of sliding grooves are opened on one side of each housing. Four sets of fixing rods 703 on the same side are slidably installed inside the corresponding two sets of sliding grooves to facilitate the stable movement of the clamping plate 704 and prevent it from rotating during movement.

[0025] In this embodiment, during use, when installing the brake disc 3, pulling the pull plate 805 causes the pull plate 805 to move the pull rod 804 and the first inclined block 801. Simultaneously, the first inclined block 801 compresses the first spring 806. At this time, the reset of the two sets of second springs 807 ensures that the inclined surfaces of the two sets of second inclined blocks 802 are always in contact with the inclined surface of the first inclined block 801. This causes the two sets of second inclined blocks 802 to move the corresponding insertion rods 803 into the placement groove. The brake disc 3 is then placed on the outside of the connector. Releasing the pull plate 805, the reset action of the first spring 806 causes the first inclined block 801 to compress the two sets of second inclined blocks 802. Simultaneously, the two sets of second inclined blocks 802 compress the second spring 807, causing the insertion rods 803 to move and insert into the interior of the brake disc 3. Then, the motor 12 drives the connector and the brake disc 3 to rotate. Disassembly is similar; by pulling the pull plate 805 again... After being stretched and reset by spring 806 and spring 807, the brake disc 3 can be disassembled. The hydraulic cylinder 10 is activated, and hydraulic oil is injected into the hydraulic channel 11, pushing the piston blocks 5 on both sides to move outward. A housing is fixedly installed on one side of the piston block 5. As the piston block 5 moves outward, the housing also moves outward synchronously. By rotating the rocker arm 706, the double-acting screw 701 is driven to rotate. Since the outer side of the double-acting screw 701 is threaded with two sets of threaded plates 702, the rotation of the double-acting screw 701 will cause the two sets of threaded plates 702 to move relative to each other in the axial direction of the double-acting screw 701. As the threaded plates 702 move, the clamping plate 704 also moves, thereby clamping the brake pad 6 between the two sets of clamping plates 704, ensuring that the clamping plate 704 can accurately clamp the brake pad 6. The motor 12 drives the brake disc 3 to rotate, simulating the actual rotation condition of the brake disc 3 when the vehicle is braking. At this time, the brake pad 6, which is clamped on the bracket 4, comes into contact with the rotating brake disc 3. By observing the friction between the brake pad 6 and the brake disc 3 and measuring the wear degree of the brake pad 6, the performance of the brake pad 6 can be tested. During the testing process, the guide rod 15, short plate 13, and spring 14 inside the rectangular grooves on both sides of the bracket 4 play an auxiliary role. When the piston block 5 moves under the push of hydraulic oil, the short plate 13 moves with the piston block 5 and slides on the guide rod 15. The guide rod 15 ensures the stability of the piston block 5's movement direction. The spring 14 plays a role in buffering and resetting during the movement of the piston block 5. When the hydraulic cylinder 10 stops working or the hydraulic oil pressure changes, the elastic force of the spring 14 can make the piston block 5 and related components return to their original positions smoothly, preparing for the next test. Then, the pump body 903 is driven to draw coolant from the water tank 901 and deliver it to the spray head 905 through the connecting pipe 904. The spray head 905 sprays the coolant evenly onto the rotating brake disc 3. The coolant absorbs the heat on the brake disc 3 and can cool the brake disc 3, ensuring that the brake disc 3 is always within a suitable temperature range during the test, ensuring the accuracy of the test results and the stable operation of the equipment.
