Description

Technical Field

[0001] This utility model relates to the field of braking technology, specifically to a vehicle braking mechanism and a detection device applied to the braking mechanism. Background Technology

[0002] A braking system, broadly speaking, is a device that can decelerate, stop, or maintain a stopped state of moving parts (or moving machinery). When used in vehicles, it means a device that reduces the speed of the vehicle and changes the vehicle from a moving state to a stopped state.

[0003] A typical braking system includes components and devices such as a brake pedal (switch), brake fluid (air), master cylinder, and brake. The brake is directly connected to the wheel and is used to apply friction to the wheel, thereby reducing the wheel's speed and completing the braking.

[0004] A typical brake is mounted on a brake disc bracket. It utilizes the friction generated by the contact between the brake pads and the brake disc, and then transmits this friction to the axle and wheels for braking. However, with use, the friction between the brake disc and the brake pads causes wear. The force between the brake pads and the brake disc is provided by a hydraulic or pneumatic system. Failures can occur in any of these systems, including the brake pads, brake disc, or hydraulic (pneumatic) system. When a vehicle malfunctions, it can lead to speeding and potential danger. Therefore, it is necessary to test and maintain the braking capacity of the brakes during maintenance. However, the common testing method simply involves removing the brake pads and checking their thickness, and then checking the contact between the brake pads and the brake disc by pressing the brake pedal after replacement. This testing and maintenance method is rudimentary and lacks accuracy.

[0005] Therefore, a vehicle braking mechanism and a detection device for the braking mechanism are needed to solve the problem of accuracy in braking performance testing. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vehicle braking mechanism and a detection device applied to the braking mechanism.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A vehicle braking mechanism and a detection device applied to the braking mechanism include a first mounting block, a second mounting block, and a third mounting block arranged continuously from right to left. The first mounting block is fixedly connected to a first mounting block on a brake disc bracket. There are two second mounting blocks. The ends of the first and third mounting blocks that are close to each other are each provided with a downward-through brake disc receiving groove. The two brake disc receiving grooves are joined to form a brake disc receiving cavity with a downward opening. The inner wall of the upper section of the brake disc receiving groove is provided with a front-to-back through friction pad receiving groove, and the friction pad receiving groove also has an upward through opening. The two second mounting blocks are arranged on... The first mounting block and the third mounting block are located at the front upper and rear upper positions respectively, abutting against the first mounting block and the third mounting block. The second mounting block is located at the front and rear openings of the friction plate receiving groove and closes the opening of the friction plate receiving groove in the left and right directions. The first mounting block, the second mounting block, and the third mounting block are fixedly connected by bolts. Friction plate mounting blocks are provided in the two friction plate receiving grooves. A friction plate is fixedly connected to the end of the friction plate mounting block away from the inner wall of the friction plate receiving groove. The first mounting block is provided with a hydraulic connecting cylinder that penetrates to the friction plate receiving groove on the first mounting block. The hydraulic connecting cylinder is connected to the vehicle braking system. A piston is provided in the hydraulic connecting cylinder that abuts against the end of the friction plate mounting block away from the friction plate.

[0008] By adopting the above technical solution, and utilizing the detachable connection of the first mounting block, the second mounting block, and the third mounting block, the bolts can be loosened and the outlet of the brake pad can be widened when installing or replacing the brake pad, making it easier to remove the brake pad. At the same time, the hydraulic connecting cylinder is connected to the vehicle's braking system (specifically, the hydraulic connecting cylinder is connected to the hydraulic (pneumatic) system in the braking system. When the hydraulic (pneumatic) system applies pressure, it pushes the piston to move. The piston pushes the brake pad in the outlet towards the brake disc and applies pressure to it, thereby increasing the maximum static friction between the two).

[0009] The present invention is further configured such that the upward openings of the two friction pad receiving grooves are joined together to form a large opening, and a loop-shaped connecting rod is provided at the large opening, and the two sides of the connecting rod pass through the first mounting block and the third mounting block.

[0010] By adopting the above technical solution, on the one hand, the wear condition of the friction pad can be directly observed through the large opening; on the other hand, the large opening allows the upper part of the detection device of the vehicle braking mechanism to pass through, and thus the detection device can be installed on the first mounting block, the second mounting block and the third mounting block for easy detection.

[0011] The present invention is further configured such that the distance between the outlet and the left and right sides is greater than the thickness of the friction plate mounting block plus the friction plate in the left and right sides.

[0012] By adopting the above technical solution, the movement distance of the friction plate mounting block and the friction plate can be controlled by controlling the distance in the left and right directions of the outlet. At the same time, the thickness of the friction plate after wear can be observed from the outlet. When the remaining thickness of the friction plate is less than one-quarter of the width of the outlet (this value is adjusted according to the friction plate material), it is a warning state and replacement is required.

[0013] A detection device for a vehicle braking mechanism includes a pressure detector. A protruding block with a large opening is fixedly connected to the side end face of the pressure detector. A mounting plate extending in a forward-backward direction and located above a second mounting block is detachably connected to the end of the protruding block away from the pressure detector. A threaded hole is provided on the upper end face of the second mounting block. A through hole is provided through the mounting plate. The mounting plate and the second mounting block are detachably connected by bolts passing through the through hole and threadedly connected to the threaded hole. An electrical connection hole is provided on the side of the pressure detector away from the protruding block. The electrical connection hole is electrically connected to an external display.

[0014] By adopting the above technical solution, the protruding block on the pressure detector can pass through the large opening, and the mounting plate can be detachably connected to the protruding block by bolts. Then, the other end of the mounting plate is connected to the upper surface of the second mounting block by bolts, thus completing the connection between the pressure detector and the first, second, and third mounting blocks, and making the pressure detector surface contact the force-bearing part. Then, the connecting wire is inserted into the power connection hole, that is, the several pressure detectors inside the pressure detector are electrically connected to the external display. Then, the piston is periodically controlled to apply pressure to the pressure detector, and the corresponding value is displayed on the display. The control component that controls the piston to apply pressure to the pressure detector can be set as a node at one-fifth (the value can be adjusted as needed) of the control distance (that is, six detection points are set in its entire control range), to detect the pressure value at different control positions and plot its pressure change curve, and then view the pressure change curve of the pressure applied to the brake system, and then determine whether the hydraulic (pneumatic) system has failed. At the same time, the connecting wire connection method allows the display to be close to the position of the brake component, which not only facilitates detection, but also allows viewing its feedback speed, and further detects the braking effect.

[0015] The present invention is further configured such that the mounting plate has an elastic steel sheet.

[0016] By adopting the above technical solution, when installing the detection device on the first mounting block, the second mounting block, and the third mounting block, since the sizes of the first mounting block, the second mounting block, and the third mounting block are different for different vehicles, when installing the detection device, it is only necessary to ensure that the pressure detector is aligned with the piston position, and then install the elastic mounting plate. The elasticity of the mounting plate can be used to make the detection device adapt to the first mounting block, the second mounting block, and the third mounting block of different sizes. Specifically, the mounting plate can be provided with several connecting threaded holes to adapt to the first mounting block, the second mounting block, and the third mounting block of different sizes (only the state with one connecting threaded hole is shown in the figure).

[0017] In summary, this utility model has the following beneficial effects:

[0018] By utilizing the detachable connection of the first, second, and third mounting blocks, when replacing the friction plate mounting block and friction plate, the first, second, and third mounting blocks can be loosened first to complete the disassembly of the friction plate mounting block and friction plate. At the same time, the wear thickness of the friction plate can be observed through the outlet, which can roughly determine whether the friction plate mounting block and friction plate need to be replaced. Simultaneously, the detection device can be directly inserted into the position between the two friction plates and fixed by using the connecting thread hole and large opening on the second mounting block. Then, pressure is applied to the pressure detector by controlling the braking component, and the pressure signal is transmitted to an external display through the pressure detector and connecting wire, so as to view the corresponding pressure value in real time and thus judge the braking effect.

[0031] The present invention will now be described in detail with reference to the accompanying drawings of the embodiments thereof. Example

[0032] This describes a vehicle braking mechanism and a detection device applied to the braking mechanism, such as... Figures 1 to 10As shown, the device includes a first mounting block 11, a second mounting block 12, and a third mounting block 13 arranged continuously from right to left. The first mounting block 11 is fixedly connected to the brake disc bracket. There are two second mounting blocks 12. Both the first mounting block 11 and the third mounting block 13 have downward-through brake disc receiving grooves 22 at their adjacent ends. The two brake disc receiving grooves 22 are joined to form a brake disc receiving cavity 15 with a downward opening. The inner wall of the upper section of the brake disc receiving groove 22 has a front-to-back through friction pad receiving groove 16, and the friction pad receiving groove 16 also has an upward through opening. The two second mounting blocks 12 are... The first mounting block 11, the second mounting block 12, and the third mounting block 13 are positioned between the first mounting block 11 and the third mounting block 13, respectively, and abut against the first mounting block 11 and the third mounting block 13. The second mounting block 12 is located at the outlet 23 of the front and rear openings of the friction plate receiving groove 16, and closes the opening of the friction plate receiving groove 16 in the left and right directions. The first mounting block 11, the second mounting block 12, and the third mounting block 13 are fixedly connected by bolts. Friction plate mounting blocks 24 are provided in the two friction plate receiving grooves 16. A friction plate 25 is fixedly connected to one end of the friction plate mounting block 24 away from the inner wall of the friction plate receiving groove 16. The first mounting block 11 is provided and penetrates through the first mounting block 11. A hydraulic connecting cylinder 27 is located at the upper friction pad receiving groove 16 and is connected to the vehicle braking system. A piston 21 is installed inside the hydraulic connecting cylinder 27, abutting against the end of the friction pad mounting block 24 away from the friction pad 25. The upward openings of the two friction pad receiving grooves 16 are joined together to form a large opening, and a loop-shaped connecting rod 14 is installed at this large opening. The two opposite sides of the connecting rod 14 penetrate the first mounting block 11 and the third mounting block 13. The distance between the outlet 23 in the left and right directions is greater than the thickness of the friction pad mounting block 24 plus the friction pad 25 in the left and right directions. A detection device for a vehicle braking mechanism includes a pressure detector 17. The pressure detector 17 has a fixed extension block 18 that can pass through a large opening. The end of the extension block 18 away from the pressure detector 17 is detachably connected to a mounting plate 19 that extends forward and backward and is located above the second mounting block 12. The upper end of the second mounting block 12 has a connecting threaded hole 20. The mounting plate 19 has a through hole, and the mounting plate 19 and the second mounting block 12 are detachably connected by bolts passing through the through hole and threadedly connected to the connecting threaded hole 20. The side of the pressure detector 17 away from the extension block 18 has an electrical connection hole 26, which is electrically connected to an external display. The mounting plate 19 has a flexible steel sheet.

[0033] By utilizing the detachable connection structure of the first mounting block 11, the second mounting block 12, and the third mounting block 13, these components can be cast separately, greatly reducing casting difficulty and production costs. The detachable connection also facilitates the disassembly of the friction plate mounting block 24 and the friction plate 25. The connecting rod 14 prevents the first and second mounting blocks 11 and 12 from falling off during disassembly. The large opening allows inspectors to directly observe the wear condition of the friction plate 25. Furthermore, the width of the drain outlet 23 allows for a rough assessment of the wear thickness of the friction plate 25. When the end face of the friction plate 25 can be exposed at the drain outlet 23 or when its remaining thickness is minimal, the friction plate mounting block 24 and the friction plate 25 can be replaced. The second mounting block 12 is also fixedly connected to an abutment block 28, and the friction plate mounting block 24 has a through groove 2 that abuts against the abutment block 28. 9. This allows the abutment block 28 to prevent the friction pad mounting block 24 and the friction pad 25 from falling out of the outlet 23. The protruding block 18 on the pressure detector 17 extends from the large opening. The protruding block 18 and the second mounting block 12 are then connected by the mounting plate 19, thus completing the connection between the pressure detector 17 and the first mounting block 11, the second mounting block 12, and the third mounting block 13. The brake system is then driven by the fixing component, which pushes the piston 21 to press the friction pad mounting block 24 and the friction pad 25 against the pressure detector 17. The pressure detector 17 then detects the pressure applied by the piston 21, thereby detecting the brake pressure of the brake system and judging the braking effect (specifically, detecting whether there is a fault in the hydraulic (pneumatic) system of the brake system). At the same time, the pressure signal received by the pressure detector 17 can be transmitted to the display via the connecting wire to judge the pressure magnitude. The display can also be placed directly on the position of the brake component to judge its feedback time, further checking the braking effect.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
