Abstract
Description
Technical Field
[0001] This utility model belongs to the field of clutch repair technology, specifically relating to a clutch quick venting device. Background Technology
[0002] Most off-road vehicles currently use manual transmissions, requiring the clutch to be depressed for shifting. These clutches are typically fluid clutches, consisting mainly of a clutch pedal, master cylinder, slave cylinder, and hydraulic lines. When the master cylinder, slave cylinder, or lines are damaged, air must be purged from the hydraulic system after replacement to ensure proper functioning. This air purging is the most time-consuming part of clutch operation repair. For example, purging the air from a Shaanxi Automobile 2190 transport truck typically takes 1 to 2 hours, requiring the clutch to be depressed hundreds of times. In contrast, replacing the master cylinder and slave cylinder only takes 8 to 15 minutes, resulting in low repair efficiency. A purging system is urgently needed to improve repair efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a quick clutch venting device that can quickly complete the clutch venting process, ensure good venting effect, and has a small overall size, making it easy to carry and suitable for use in the field.
[0004] The specific technical solution adopted by this utility model is as follows:
[0005] A clutch quick-release device includes a reservoir. The upper end of the reservoir is fixedly connected to a cover plate via screw holes and bolts. The cover plate is fixedly connected to the bottom end of a mounting box. An oil pump is fixedly installed inside the mounting box. The oil inlet of the oil pump is fixedly connected to the upper end of an oil inlet pipe. An oil suction hood is fixedly installed at the bottom end of the oil inlet pipe. The inner wall of the mounting box is also fixedly connected to the upper end of a float sensor. The bottom end of the float sensor extends to the bottom of the reservoir.
[0006] A filling assembly is also fixedly installed inside the cover plate. The oil pump and float sensor are both electrically connected to the control host, which is fixedly installed on the front side of the mounting box.
[0007] The filling assembly includes a fixing tube, which is fixedly installed inside the cover plate. The bottom end of the inner wall of the fixing tube is fixedly connected to the outer side of the fixing ring, and the upper end of the fixing tube is threadedly connected to the threaded cap.
[0008] The inner side of the fixing ring overlaps with the outer side of the connecting pipe, and positioning grooves are provided at both ends of the upper surface of the fixing ring.
[0009] The two positioning slots are respectively fitted with two positioning blocks, and the opposite ends of the two positioning blocks are fixedly connected to the outer side of the connecting pipe.
[0010] The upper surface of each positioning block is fixedly connected to the bottom end of a telescopic rod and a spring, and the two springs are respectively sleeved on the outside of the two telescopic rods.
[0011] The upper ends of the telescopic rod and the spring on the same side are fixedly connected to the bottom end of the pull rod. The upper ends of the two pull rods are respectively fitted into two countersunk holes, which are respectively opened on the left and right sides of the sealing ring.
[0012] The outer side of the sealing ring is provided with a sealing rubber ring that fits tightly against the fixing tube. The inner side of the sealing ring is fixedly connected to the outer side of the connecting tube. The upper ends of the two countersunk holes are respectively threaded to two screws.
[0013] The bottom end of the sealing ring is fixedly connected to the upper end of the high-precision filter screen, which extends into the liquid storage tank.
[0014] The oil pump outlet is fixedly connected to one end of the oil outlet pipe, the other end of the oil outlet pipe passes through the side wall of the mounting box and extends to its outside, the other end of the oil outlet pipe is sleeved with one end of the conversion connector, and a pressure gauge is fixedly installed on the oil outlet pipe.
[0015] A power interface is fixedly installed on the left side of the installation box. The power interface is electrically connected to the control host. The control host is equipped with a pressure regulation module and an audible alarm module.
[0016] The technical effects achieved by this utility model are as follows:
[0017] This utility model's oil pump draws clutch and brake fluid from the reservoir, allowing the fluid to be delivered to the clutch booster via the outlet pipe and adapter. From there, it is reversed through the clutch oil circuit system to the clutch cylinder, and finally to the clutch reservoir. Utilizing the principle of upward air movement, under the pressure of the clutch and brake fluid, all air in the clutch booster, clutch cylinder, and clutch oil circuit is expelled into the clutch reservoir. This allows for rapid clutch bleed operation, ensuring excellent bleed effect, significantly reducing bleed time, and improving clutch maintenance efficiency.
[0018] This invention features a filling assembly within the cover plate, and a high-precision filter within the filling assembly. This allows for the filtration of clutch / brake fluid into the reservoir via the high-precision filter, preventing impurities from entering the reservoir and clogging the oil pump and clutch oil passages. Furthermore, when cleaning the high-precision filter, the screw can be unscrewed from the countersunk hole, and a spring force pushes the pull rod upwards, extending it from the countersunk hole. The user can then hold the pull rod to assemble and disassemble the connecting pipe and the high-precision filter. The screw securing the pull rod below the sealing ring prevents it from being contaminated by clutch / brake fluid. This allows for the use of a clean pull rod to handle the high-precision filter, avoiding the need for the user to directly handle the connecting pipe and have their hands contaminated with oil, further enhancing the functionality and practicality of the device.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0027] like Figure 1-5 As shown, the clutch quick exhaust device includes a reservoir 1. The upper end of the reservoir 1 is fixedly connected to the cover plate 2 through screw holes and bolts. The cover plate 2 is fixedly connected to the bottom end of the mounting box 3. An oil pump 12 is fixedly installed inside the mounting box 3. The oil inlet of the oil pump 12 is fixedly connected to the upper end of the oil inlet pipe 11. An oil suction cover 9 is fixedly installed at the bottom end of the oil inlet pipe 11. The inner wall of the mounting box 3 is also fixedly connected to the upper end of the float sensor 10. The bottom end of the float sensor 10 extends to the bottom of the reservoir 1. By installing the float sensor 10 inside the reservoir 1, when the oil in the reservoir 1 is poured into the clutch pipeline, the float sensor 10 can be used to monitor the remaining oil in the reservoir 1 and transmit the oil volume data to the control host 5. When the oil level in the reservoir 1 is low, the control host 5 controls the sound alarm module installed inside to work and emit an alarm sound.
[0028] The cover plate 2 also has a filling component 8 fixedly installed inside. The oil pump 12 and the float sensor 10 are all electrically connected to the control host 5, which is fixedly installed on the front side of the mounting box 3.
[0029] Furthermore, the filling component 8 includes a fixing tube 81, which is fixedly installed inside the cover plate 2. The bottom end of the inner wall of the fixing tube 81 is fixedly connected to the outer side of the fixing ring 84, and the upper end of the fixing tube 81 is threadedly connected to the threaded cap 88.
[0030] Furthermore, the inner side of the fixing ring 84 overlaps with the outer side of the connecting pipe 83, and positioning grooves 86 are provided at both ends of the upper surface of the fixing ring 84.
[0031] Furthermore, the two positioning grooves 86 are respectively sleeved with the two positioning blocks 87, and the opposite ends of the two positioning blocks 87 are fixedly connected to the outer side of the connecting pipe 83. By setting the positioning blocks 87 and positioning grooves 86, the connecting pipe 83 is connected to the fixing ring 84, thereby using the insertion of the positioning blocks 87 and positioning grooves 86 to limit and support the connecting pipe 83 and the high-precision filter 85, effectively improving the stability of the connecting pipe 83 and the high-precision filter 85.
[0032] Furthermore, the upper surface of each positioning block 87 is fixedly connected to the bottom end of a telescopic rod 812 and a spring 811, with the two springs 811 respectively sleeved on the outside of the two telescopic rods 812.
[0033] Furthermore, the upper ends of the telescopic rod 812 and the spring 811 on the same side are fixedly connected to the bottom end of the pull rod 810. The upper ends of the two pull rods 810 are respectively fitted into the two countersunk holes 89. The two countersunk holes 89 are respectively opened on the left and right sides of the sealing ring 82. By setting the telescopic rod 812 and the spring 811, the positioning block 87 is connected to the pull rod 810. Thus, after the screw is unscrewed from the upper end of the countersunk hole 89, the elastic force of the spring 811 pushes the pull rod 810 upward, causing the pull rod 810 to extend from the upper end of the countersunk hole 89.
[0034] Furthermore, a sealing ring is provided on the outer side of the sealing ring 82 to fit tightly with the fixing tube 81. The inner side of the sealing ring 82 is fixedly connected to the outer side of the connecting tube 83. The upper ends of the two countersunk holes 89 are respectively threaded with two screws. By setting the sealing ring 82 on the upper end of the connecting tube 83 to fit with the fixing tube 81, the sealing ring 82 is used to seal and isolate the pull rod 810, thereby preventing the oil from contacting the pull rod 810 and causing contamination when the oil is poured in. Thus, when disassembling and assembling the high-precision filter 85, the high-precision filter 85 can be picked up with a clean pull rod 810, thereby avoiding the user directly picking up the connecting tube 83 and having their hands contaminated with oil that is difficult to clean.
[0035] Furthermore, the bottom end of the sealing ring 82 is fixedly connected to the upper end of the high-precision filter screen 85, which extends into the liquid storage tank 1.
[0036] Furthermore, the oil outlet of the oil pump 12 is fixedly connected to one end of the oil outlet pipe 7, the other end of the oil outlet pipe 7 passes through the side wall of the mounting box 3 and extends to its outside, the other end of the oil outlet pipe 7 is sleeved with one end of the conversion connector 13, and a pressure gauge 6 is fixedly installed on the oil outlet pipe 7.
[0037] Furthermore, a power interface 4 is fixedly installed on the left side of the mounting box 3. The power interface 4 is electrically connected to the control host 5. The control host 5 is equipped with a pressure regulation module and an audible alarm module. When using this device, one end of the power cord can be plugged into the power interface 4, and the other end of the power cord can be clamped onto the vehicle battery terminal to supply power to the device, so that this device can assist in clutch maintenance and exhaust operations anytime and anywhere.
[0038] The working principle of this utility model is as follows: When using this device, the user can first rotate the threaded cap 88 to remove it from the upper end of the fixed tube 81. Then, the clutch brake fluid is added to the reservoir 1 through the connecting tube 83 and the high-precision filter 85. When adding clutch brake fluid, the high-precision filter 85 is used to filter impurities in the fluid. After adding an appropriate amount of fluid to the reservoir 1, the fixed tube 81 is sealed with the threaded cap 88. Then, the user can connect the appropriate adapter 13 to the oil outlet tube 7 according to the vehicle model being repaired, and connect the adapter 13 to the clutch slave cylinder oil pipe. Then, one end of the power cord is connected to the power interface 4, and the other end of the power cord is clamped to the vehicle. The device is powered by the battery terminal. At this time, the user can control the oil pump 12 to work through the control host 5. When the oil pump 12 works, it uses the oil suction hood 9 and the oil inlet pipe 11 to suck out the oil in the reservoir 1. During this process, the oil in the reservoir 1 is filtered again by the oil suction hood 9. Then the oil is poured into the clutch pipeline through the oil outlet pipe 7 and the conversion connector 13 to purge the air from the clutch slave pump to the master pump oil line. During this process, the filling pressure of the oil can be measured by the pressure gauge 6 and the filling pressure can be adjusted by the pressure adjustment module in the control host 5. After the venting is completed, the oil pump 12 is turned off and the conversion connector 13 is disconnected from the clutch slave pump oil line.
[0039] When cleaning the high-precision filter 85, the user can remove the threaded cap 88 from the upper end of the fixing tube 81, and then use a flathead screwdriver to remove the screw from the countersunk hole 89. At this time, the spring 811 pushes the pull rod 810 upward, causing the pull rod 810 to extend from the upper end of the countersunk hole 89. The user can hold the pull rod 810 to remove the connecting tube 83, sealing ring 82, and high-precision filter 85 from the fixing tube 81 for cleaning. After cleaning, the connecting tube 83 and high-precision filter 85 can be put back into the fixing tube 81, and the positioning block 87 can be inserted into the positioning groove 86. At this time, the user can take the screw and contact the upper end of the pull rod 810, and press the pull rod 810 downward to sink the pull rod 810 into the countersunk hole 89. At this time, the screw can be rotated to connect the screw with the upper end of the countersunk hole 89 to restrict the position of the pull rod 810. Then the threaded cap 88 can be reconnected to the upper end of the fixing tube 81.
[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
