Description

Technical Field

[0001] This utility model relates to the field of brake disc testing technology, specifically a multi-disc parallel braking mechanism for brake disc wear resistance testing. Background Technology

[0002] Brake discs are a key component of a car's braking system. Their primary function is to generate friction with the calipers, thereby slowing or stopping the vehicle. When the driver presses the brake pedal, the hydraulic system pushes the calipers to clamp the sides of the brake disc. Through friction, the vehicle's kinetic energy is converted into heat energy, achieving the braking effect. Because brake discs are directly related to driving safety, their quality and performance must strictly meet standards. Therefore, before leaving the factory, manufacturers conduct random sampling tests on brake discs to ensure that each batch of products meets the specified pass rate, guaranteeing the safety of drivers and passengers.

[0003] For example, patent number CN 212904347 U discloses a brake pad wear resistance testing device, including a device frame, a wheel inside the device frame, a connecting assembly inside the wheel, a drive motor on one side of the connecting assembly embedded in the device frame, a support rod on the other side of the connecting assembly, a bearing assembly inside the support rod, a shaft inside the connecting assembly with the bearing assembly at one end embedded in the support rod, a mounting frame on the upper part of the device frame, a bracket below the mounting frame, a brake disc below the bracket, brake pads inside the brake disc, and an electric push rod on the outer side of the bracket. By controlling the brake disc with the electric push rod, the brake disc and both sides of the wheel can be brought into contact to generate friction, thereby achieving the test of brake pad wear resistance. The device has a simple structure and low cost.

[0004] For example, patent number CN 210603084 U discloses a testing device for the wear resistance performance of brake discs, relating to the field of brake disc technology. This invention includes a base plate, a lifting mechanism and a frame fixed to the top of the base plate, a housing fixed to the top end face of the frame by bolts, a support rod fixed to the top of the lifting mechanism, one end of the support rod rotatably connected to an upper drive mechanism that cooperates with the housing, a bracket fixed inside the housing by bolts, a support sleeve passing through the bracket in a ring at equal intervals, a telescopic rod fixed inside the support sleeve, and a support disc fixed to the top of the telescopic rod. This invention controls the contact tightness between the friction disc and the brake disc by fixing the brake disc to the upper drive mechanism and controlling the lifting and lowering of the friction disc. The relative movement of the friction disc and the brake disc detects the wear resistance and service life of the brake disc. Furthermore, it can change the testing environment of the brake disc during testing, simulating the normal state of the brake disc in a real environment, providing accurate data for the detection of brake disc performance.

[0005] While the technical solution proposed in the aforementioned patent can achieve the basic function of testing brake pad wear resistance, it still has significant limitations in practical applications. Specifically, the testing device can only perform wear resistance testing on a single brake pad at a time, and cannot achieve simultaneous testing of multiple brake pads. In addition, the testing process lacks simulation of the real braking environment. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a multi-disc parallel braking mechanism for brake disc wear resistance testing, which solves the problems of the above-mentioned testing devices being able to test only a single brake pad at a time and being unable to test multiple brake pads simultaneously, as well as the lack of simulation of the real braking environment during the testing process.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a multi-disc parallel braking mechanism for a brake disc wear resistance testing mechanism, comprising a braking mechanism and a rotating mechanism. The rotating mechanism is provided with a support frame, and a guide frame is provided above the support frame. A left moving block and a right moving block are provided inside the guide frame. A spring guide column box is provided above the guide frame, and a right guide column frame and a left guide column frame are provided inside the guide column box. Guide columns are provided on the left and right guide column frames, and each guide column is provided with a return spring. One end of the spring contacts the spring guide column box. A push-pull rod is provided at the right end of the right and left guide column frames, and the other end of the push-pull rod is connected to the rotating frame. A connecting plate is provided below the rotating frame, and a lever shaft is provided on the connecting plate. One end of the lever shaft is connected to the rotating frame, and the other end of the lever shaft is provided with a hydraulic cylinder. A connecting screw is provided between the connecting plate and the support frame for connection.

[0008] Preferably, four left brake pads are provided below the left moving block, and four right brake pads are provided below the right moving block.

[0009] Preferably, an outer bearing ring and an inner bearing ring are provided above the support frame, a rolling element is provided between the inner bearing ring and the outer bearing ring, and a main shaft is provided inside the inner bearing ring.

[0010] Preferably, a guide transmission frame is provided on the left side of the main shaft, the guide transmission frame is provided with five retaining blocks, the guide transmission frame is provided with four brake discs, the brake discs are maintained at a distance by retaining blocks, and a fixing cover plate is provided on the left side of the guide transmission frame to fix its position.

[0011] Preferably, an inertia wheel is provided on the left side of the main shaft, a driven pulley is connected to the right side of the main shaft, a transmission belt is connected to the driven pulley, a driving pulley is connected to the other end of the transmission belt, and a rotary motor is connected to the driving pulley.

[0012] (III) Beneficial Effects This utility model provides a multi-disc parallel braking mechanism for a brake disc wear resistance testing device. It has the following advantages: This multi-disc parallel braking mechanism significantly improves testing efficiency. Traditional testing devices can only test a single brake pad at a time, while this mechanism, by setting up four brake discs, can simultaneously perform wear resistance testing on multiple brake discs, greatly shortening the testing time and improving production efficiency. It is especially suitable for quality inspection in large-scale brake disc production, enabling the sampling inspection of a large number of products to be completed in a shorter time.

[0013] This device can better simulate real braking environments. The inertia wheel in the device simulates the inertia of a vehicle during driving, causing the brake discs to experience loads closer to those in actual driving during testing, making the test results more valuable. During actual braking, the vehicle's inertia exerts a significant force on the brake discs. By incorporating the inertia wheel, the testing process can more realistically reflect the wear resistance of the brake discs in actual use, providing more accurate data for brake disc quality assessment.

[0014] This device is based on an improvement of existing equipment, so the improvement cost is relatively low and it will not cause a large amount of existing equipment to be discarded. It ensures the processing effect while reducing the investment in improvement costs, making it suitable for large-scale production. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-7This utility model provides a technical solution: a multi-disc parallel braking mechanism for a brake disc wear resistance testing mechanism, including a braking mechanism 1 and a rotating mechanism 2. The rotating mechanism 2 is provided with a support frame 201. An outer bearing ring 202 and an inner bearing ring 203 are arranged above the support frame 201. A rolling element 204 is arranged between the inner bearing ring 203 and the outer bearing ring 202. A main shaft 205 is arranged inside the inner bearing ring 203. A guide transmission frame 206 is arranged on the left side of the main shaft 205. The guide transmission frame 206 is provided with five retaining blocks 207. The guide transmission frame 206 is equipped with four brake discs 208, and the distance between the brake discs 208 is maintained by retaining blocks 207. A fixing cover plate 209 is provided on the left side of the guide transmission frame 206 to fix its position. An inertia wheel 210 is provided on the left side of the main shaft 205, and a driven pulley 211 is connected to the right side of the main shaft 205. The driven pulley 211 is connected to a transmission belt 213, and the other end of the transmission belt 213 is connected to a driving belt 212. The driving pulley 212 is connected to a rotary motor 214. A guide frame 1 is provided above the support frame 201. 01, the guide frame 101 is internally provided with a left moving block 103 and a right moving block 104. Four left brake pads 114 are provided below the left moving block 103, and four right brake pads 115 are provided below the right moving block 104. A spring guide post box 102 is provided above the guide frame 101. A right guide post frame 106 is provided inside the guide post box 102, and a left guide post frame 105 is provided inside the guide post box 102. Guide posts 107 are provided on the left and right guide post frames 105 and 106, and each guide post 107 is provided with a return spring 108. One end of the spring 108 is in contact with the spring guide post box 102. The right end of the right guide post frame 106 and the left guide post frame 105 is provided with a push-pull rod 109. The other end of the push-pull rod 109 is connected to a rotating frame 110. The rotating frame 110 has a connecting plate 111 below it. The connecting plate 111 is provided with a toggle shaft 112. One end of the toggle shaft 112 is connected to the rotating frame 110. The other end of the toggle shaft 112 is provided with a hydraulic cylinder 113. The connecting plate 111 and the support frame 201 are connected by a connecting screw 116.

[0019] During operation, the four brake discs 208 and the inertia wheel 210 are first installed on the main shaft 205, and then the brake mechanism 1 is covered. The rotary motor 214 is started, which drives the drive pulley 212 to rotate. The drive pulley 212 drives the driven pulley 211 to rotate through the transmission belt 213, thereby causing the main shaft 205 to start rotating. The rotation of the main shaft 205 causes the brake discs 208 and the inertia wheel 210 to rotate synchronously, simulating the movement of the brake discs 208 when the vehicle is in motion. When the brake discs 208 reach a certain speed, the hydraulic cylinder 113 is activated. The hydraulic cylinder 113 pushes the rotating frame 110 to rotate through the lever shaft 112. The rotating frame 110 drives the push-pull rod 109 to move, and the push-pull rod 109 pushes the left guide column frame 105 and the right guide column frame 106 to move within the spring guide column box 102. At this time, the return spring 108 on the guide post 107 is compressed, and the movement of the left guide post bracket 105 and the right guide post bracket 106 causes the left moving block 103 and the right moving block 104 to move towards each other within the guide frame 101. As the left moving block 103 and the right moving block 104 move, the left brake pad 114 and the right brake pad 115 gradually approach and clamp the brake disc 208, generating friction and braking the brake disc 208. During this process, the inertia wheel 210 simulates the inertia of the vehicle during driving, so that the brake disc 208 bears a load closer to that of actual driving during the test, making the test results more reflective of the wear resistance of the brake disc 208 in actual use.

[0020] In summary, this multi-disc parallel braking mechanism significantly improves testing efficiency. Conventional testing equipment can only test one brake pad at a time, but this mechanism, with its four brake discs, can simultaneously perform wear resistance testing on multiple brake discs, greatly reducing testing time and improving production efficiency. It is particularly suitable for quality inspection processes in large-scale brake disc production, enabling the completion of large-volume product sampling inspections in a shorter time.
