Description

Technical Field

[0001] This utility model relates to the field of low-leakage automotive clutch pump technology, specifically to a low-leakage automotive clutch pump. Background Technology

[0002] The clutch pump is the core actuator of the clutch control system. Its core function is to convert the "mechanical force" of the driver pressing the clutch pedal into "hydraulic thrust", which ultimately pushes the clutch to disengage, realizes the power cut-off between the engine and the transmission, and creates conditions for gear shifting.

[0003] For example, a car clutch pump body with announcement number "CN211009637U" includes an elastic sealing block and a sealing mechanism. The two work together to better seal the oil inlet. The first sealing gasket can effectively prevent oil from entering the buffer chamber. The buffer chamber, opening, and sealing cover structure can collect a small amount of leaked oil, preventing environmental pollution and reducing waste. However, in the use of a car clutch pump, the internal buffer space is limited, and excess oil will leak through the pull shaft. In addition, the sealing cover at the bottom of the buffer groove needs to be opened and closed manually, which will cause excessive leakage at the connection between the buffer space and the pull shaft, resulting in an increase in the overall oil leakage of the car clutch pump and affecting the normal use of the car clutch pump. Utility Model Content

[0004] The purpose of this invention is to solve the problem of increased overall oil leakage in automotive clutch pumps, which affects the normal use of automotive clutch pumps, and to propose a low-leakage automotive clutch pump.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a low-leakage automotive clutch pump, including a vertical pipe, the bottom of which is connected to the automotive clutch pump, a receiving structure connected to the bottom right side of the automotive clutch pump, a mounting structure connected to the left side of the outer wall of the automotive clutch pump, and a recessed plate fixed to the right side of the automotive clutch pump.

[0006] This setting: The car's clutch pump model is MB-100, which converts the "mechanical force" of the driver pressing the clutch pedal into "hydraulic thrust," ultimately pushing the clutch to disengage and cutting off power between the engine and the transmission.

[0007] Preferably, the receiving structure includes a first straight tube and a second straight tube. The top of the first straight tube is connected to the bottom right side of the automotive clutch pump. The lower part of the outer wall of the first straight tube is inserted into the inner wall of the second straight tube. The bottom of the second straight tube is connected to a housing. A plug plate is fixedly connected to the inner wall of the first straight tube, and a groove plate is fixedly connected to the top of the plug plate.

[0008] This feature: The stopper plate is made of fluororubber, which has sealing and resilience properties, as well as good corrosion and oxidation resistance. When the space on the right side decreases and the air pressure increases, the stopper plate in the first straight pipe is subjected to air pressure and will open downwards. Then, the oil in the space on the right side enters the outer shell through the first and second straight pipes. When the space on the right side increases and the air pressure decreases, the stopper plate, due to its own rubber material, has a rebound force and will close at the opened position to complete the closure of the first straight pipe.

[0009] Preferably, the outer wall of the groove plate is fixedly connected to the inner wall of the first straight tube.

[0010] This design, with the inclined surface of the inner wall of the tank plate, facilitates the downward flow of oil and prevents excessive oil accumulation at the top of the plug plate.

[0011] Preferably, flanges are fixed to the outer walls of the first straight pipe, the second straight pipe, and the vertical pipe.

[0012] This setting: The flanges on the outer walls of the first and second straight pipes are fitted with bolts to facilitate their fixing, and the flanges on the outer walls of the vertical pipes are fitted with bolts to facilitate their fixing with the outer flanges of the automotive oil pipes.

[0013] Preferably, the left side of the automotive clutch pump is connected to a horizontal pipe.

[0014] This setting: The outer wall of the horizontal tube is connected to the oil outlet pipe of the car, which allows the oil in the car's clutch pump to be discharged at the left end of the horizontal tube.

[0015] Preferably, a protective sleeve is fixed to the left end of the outer wall of the horizontal tube.

[0016] This feature: The sheath is made of fluororubber, which can increase the sealing between the horizontal pipe and the oil outlet pipe, while also having good corrosion resistance and oxidation resistance.

[0017] Preferably, the mounting structure includes a bracket and a protective pad, the top slot of the bracket is fixedly connected to the outer wall of the automotive clutch pump, the front side of the bracket is fixedly connected to the rear end face of the protective pad, and a ring is fixedly connected below the rear end face of the bracket.

[0018] This feature: The pad is made of fluororubber, which acts as a protective layer to prevent friction between the bracket and the car.

[0019] The present invention discloses a low-leakage automotive clutch pump, which has the following advantages: When some oil enters the right-side space of the inner wall of the automotive clutch pump through the receiving structure, the movement of the plug will also change the right-side space inside the automotive clutch pump, thereby changing the air pressure in the space. When the right-side space becomes smaller, the air pressure increases. At this time, the plug plate in the first straight pipe is subjected to air pressure, and the plug plate will be pushed downward. Then, the oil in the right-side space enters the outer shell through the first and second straight pipes. When the right-side space becomes larger, the air pressure decreases, and the plug plate, due to its own rubber material, has elasticity and will close at the opened position to complete the closure of the first straight pipe. By increasing the oil storage space through the first straight pipe, the second straight pipe, and the outer shell, the overall oil leakage of the automotive clutch pump is reduced, ensuring the normal use of the automotive clutch pump.

[0022] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-5 In this embodiment, a low-leakage automotive clutch pump includes a vertical pipe 1, the bottom of which is connected to an automotive clutch pump 4, model MB-100. The automotive clutch pump 4 converts the "mechanical force" of the driver pressing the clutch pedal into "hydraulic thrust," ultimately pushing the clutch to disengage and achieving power cut-off between the engine and the transmission. A housing structure 2 is connected to the bottom right side of the automotive clutch pump 4, an mounting structure 3 is connected to the left side of the outer wall of the automotive clutch pump 4, and a recessed plate 6 is fixedly connected to the right side of the automotive clutch pump 4.

[0023] The receiving structure 2 includes a first straight pipe 201 and a second straight pipe 202. The top of the first straight pipe 201 is connected to the bottom right side of the automotive clutch pump 4. The lower part of the outer wall of the first straight pipe 201 is inserted into the inner wall of the second straight pipe 202. The bottom of the second straight pipe 202 is connected to a housing 203. The top of the inner wall of the housing 203 is inclined to facilitate oil discharge. A plug plate 204 is fixed to the inner wall of the first straight pipe 201. The plug plate 204 is made of fluororubber, which has sealing and resilience properties, as well as good corrosion resistance and oxidation resistance. A groove plate 205 is fixed to the top of the plug plate 204. The outer wall of the groove plate 205 is fixed to the inner wall of the first straight pipe 201. Flanges are fixed to the outer walls of the first straight pipe 201, the second straight pipe 202 and the vertical pipe 1. The flanges on the outer walls of the first straight pipe 201, the second straight pipe 202 and the vertical pipe 1 are fastened with bolts for easy fixing. When some oil enters the right-side space inside the car clutch pump 4 through the receiving structure 2, the movement of the plug will also change the right-side space inside the car clutch pump 4, thus changing the air pressure in the space. When the right-side space becomes smaller, the air pressure increases. At this time, the plug plate 204 in the first straight pipe 201 is subjected to air pressure, and the plug plate 204 will be pushed downward. Then, the oil in the right-side space enters the outer shell 203 through the first straight pipe 201 and the second straight pipe 202. When the right-side space becomes larger, the air pressure decreases, and the plug plate 204, due to its own rubber material, has a rebound force and will close at the opened position to complete the closure of the first straight pipe 201. By increasing the oil storage space through the first straight pipe 201, the second straight pipe 202 and the outer shell 203, the overall oil leakage of the car clutch pump is reduced, ensuring the normal use of the car clutch pump.

[0024] A horizontal pipe 5 is connected to the left side of the automotive clutch pump 4. A protective sleeve is fixed to the left end of the outer wall of the horizontal pipe 5. The protective sleeve is made of fluororubber, which can increase the sealing between the horizontal pipe 5 and the oil outlet pipe. At the same time, it has good corrosion resistance and oxidation resistance. The mounting structure 3 includes a bracket 301 and a protective pad 302. The top groove of the bracket 301 is fixed to the outer wall of the automotive clutch pump 4. The front of the bracket 301 is fixed to the rear end face of the protective pad 302. The protective pad 302 is made of fluororubber and plays a protective role to prevent friction between the bracket 301 and the automotive connection. A ring 303 is fixed to the lower part of the rear end face of the bracket 301. The ring 303 can form friction with the nut of the bolt to increase the stability of the bolt tightening.

[0025] Working principle: Automotive clutch pump installation: Connect the left horizontal pipe 5 of the car clutch pump 4 to the car's oil outlet pipe. At this time, the sheath at the end of the outer wall of the horizontal pipe 5 seals the oil outlet pipe with its own fluororubber material. At the same time, the protective gasket 302 in front of the bracket 301 will fit against the car's mounting point. Then, the bolt thread passes through the bracket 301 and connects with the round thread of the car's mounting point until the bolt nut abuts against the ring 303. At this time, the bolt and the ring 303 bracket form friction, which can prevent the bolt from loosening and ensure the stable installation of the car clutch pump 4. Next, the car's oil pipe is connected to the outer wall of the vertical pipe 1. Then, the flange of the outer wall of the vertical pipe 1 and the oil pipe are fixed by bolts. Finally, the car's power rod is connected to the inner wall of the concave plate 6. Then, the installation is completed by the pin passing through the concave plate 6 and the power rod.

[0026] When the power lever of the car is pulled to the left, it moves the concave plate 6 to the right. The moving concave plate 6 causes the shaft of the car clutch pump 4 to move to the right. At this time, the shaft moves the internal plug of the car clutch pump 4 to the right. The increased space on the left side of the inner wall of the car clutch pump 4 will draw oil from the oil pipe through the vertical pipe 1. Then the power lever moves to the left, moving the concave plate 6 and the shaft to the left. The moving shaft causes the plug on the inner wall of the car clutch pump 4 to move to the left. At this time, the valve of the oil pipe connected to the vertical pipe 1 can no longer supply fluid, and the space on the left side of the inner wall of the car clutch pump 4 becomes smaller. At this time, the oil inside the car clutch pump 4 will be discharged on the left side of the horizontal pipe 5. When the plug on the inner wall of the car clutch pump 4 moves, some oil will be squeezed into the right space.

[0027] Excess fluid collection from automotive clutch pumps: When some oil enters the right-side space inside the clutch pump 4, the movement of the plug will also change the right-side space inside the clutch pump 4, thus changing the air pressure in the space. When the right-side space decreases, the air pressure increases. At this time, the plug plate 204 in the first straight pipe 201 is subjected to air pressure, and the plug plate 204 will open downward. Then, the oil in the right-side space enters the outer casing 203 through the first straight pipe 201 and the second straight pipe 202. When the right-side space increases, the air pressure decreases. The plug plate 204 has elasticity due to its own rubber material, and will close at the opened position to complete the closure of the first straight pipe 201. The oil storage space is increased by the first straight pipe 201, the second straight pipe 202 and the outer casing 203, reducing the amount of oil leakage. The amount of oil stored in the clutch pump 4 increases, but the amount of oil used inside the clutch pump 4 remains unchanged. The oil level is monitored by the oil level gauge on the vehicle. When the oil level gauge issues a warning, it means that too much oil has been stored inside the outer casing 203 and it can be cleaned.

[0028] Turn the bolt upwards to disengage it from the outer flange of the first straight pipe 201 and the second straight pipe 202. Then pull the outer shell 203 downwards to disengage the second straight pipe 202 from the first straight pipe 201. Then pour the oil in the outer shell 203 out through the first straight pipe 201. Next, insert the second straight pipe 202 into the outer wall of the first straight pipe 201 so that the flanges on the outer walls of the two straight pipes fit together. Then, thread the bolt through the flanges of the two straight pipes to complete the fixing of the outer shell 203.

[0029] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
