Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology, specifically a dustproof and oil-leakage-proof one-way valve for automobiles. Background Technology

[0002] The working principle of a car starter one-way valve is very simple. When the starter motor starts running, it drives the starter gear to rotate. The gear then drives the engine flywheel to rotate through a chain or other gears, thus starting the engine. After the engine starts, the engine speed will gradually increase. At this time, the one-way valve comes into play. There is a clutch inside the one-way valve. When the engine speed is higher than the starter speed, the clutch will automatically disengage to prevent the starter from rotating in the opposite direction. When the engine speed drops below the starter speed, the clutch will automatically close, allowing the starter to drive the engine flywheel to rotate again, thus ensuring the normal operation of the engine.

[0003] When a one-way valve in a car is in operation, the rod on the drive gear rotates with the drive gear, and a certain gap is easily created between the rod and the housing due to the power generated by the rotation of the drive gear. This allows external dust to enter the interior of the housing, or lubricating oil inside the housing to easily escape through the gap, thus affecting the operation of the internal rollers. The internal rollers are easily affected by dust, leading to a decrease in the mechanical properties of the rollers, which in turn affects the normal operation of the one-way valve. Therefore, we propose a dustproof and oil-leakage-proof one-way valve for cars. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a dustproof and oil-leakage-proof one-way valve for automobiles. It features sealing between the housing and the round rod and drive gear through the action of a sealing gasket and sealing ring, maintaining a tight seal between the cover, drive gear, and round rod. The first sealing ring and first groove further enhance the seal between the sealing ring and the housing, preventing oil leakage. The second sealing ring and second groove further enhance the seal between the round rod and the housing, preventing dust from entering the housing. This solves the problem in automobile one-way valves where, during operation, the round rod on the drive gear rotates with the drive gear, creating a gap between the rod and the housing due to the force generated by the drive gear's rotation. This gap allows external dust to enter the housing or lubricating oil to escape, affecting the operation of the internal rollers. The internal rollers are also susceptible to dust, leading to a decrease in their mechanical properties and ultimately affecting the normal operation of the one-way valve.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned sealing effect of the sealing gasket and sealing ring, which seals the gap between the outer shell and the round rod and the drive gear, thus maintaining a tight seal between the cover and the drive gear and the round rod, the first sealing ring and the first retaining groove further enhance the seal between the sealing ring and the outer shell, preventing oil leakage from the outer shell. The second sealing ring and the second retaining groove further enhance the seal between the cover and the round rod, preventing dust from entering the outer shell. This utility model provides the following technical solution: A dustproof and oil-leakage-proof one-way valve for automobiles, comprising a cover, the surface of which is provided with an outer shell, the interior of which includes:

[0008] The protective assembly includes a sealing gasket, a sealing ring fixedly connected to the right side of the sealing gasket, a first sealing ring fixedly connected to the surface of the sealing ring, and a second sealing ring fixedly connected to the inner wall of the sealing ring. A first groove is formed on the inner wall of the outer casing, and a round rod is rotatably connected inside the sealing ring. A second groove is formed on the surface of the round rod. By setting up the protective assembly, the gaps between the outer casing and the round rod and the drive gear are sealed under the action of the sealing gasket and the sealing ring, maintaining a tight seal between the cover and the drive gear and the round rod. The first sealing ring and the first groove increase the seal between the sealing ring and the outer casing, thereby preventing oil leakage from the outer casing. The second sealing ring and the second groove increase the seal between the sealing ring and the round rod, preventing dust from entering the outer casing.

[0009] As a preferred technical solution of this utility model, the right side of the sealing gasket is fixedly connected to the left side of the outer shell, and the surface of the sealing ring is fixedly connected to the inner wall of the outer shell. The sealing gasket facilitates filling the gap between the outer shell and the drive gear, thus preventing the accumulation of dust.

[0010] As a preferred embodiment of this utility model, a drive gear is fixedly connected to the left end of the round rod, which facilitates the rotation of the round rod.

[0011] As a preferred embodiment of this utility model, the cover is provided with a transmission gear block inside, and the transmission gear block is provided with multiple ball rollers inside. One side of each of the multiple rollers is fixedly connected to a pressure cap spring with the inner wall of the transmission gear block. A washer is provided on the right side of the cover. By setting the rollers and the pressure cap spring, it is convenient for the transmission gear block to drive the cover to rotate in one direction.

[0012] As a preferred technical solution of this utility model, the right end of the round rod is fixedly connected to the left side of the roller. By setting the round rod, it is convenient to drive the transmission gear block to rotate.

[0013] As a preferred technical solution of this utility model, a spline sleeve is fixedly connected to the inner wall of the cover. The surface of the spline sleeve is sleeved with the inner wall of the washer. By setting the spline sleeve, the cover is driven by the transmission gear block, which drives the spline sleeve to rotate, thereby driving the output device driven by the spline sleeve to rotate as well.

[0016] 2. This one-way valve, by setting up protective components, seals the gap between the outer shell and the round rod and the drive gear under the action of the sealing gasket and sealing ring, so that the cover maintains the sealing between the drive gear and the round rod. Under the action of the first sealing ring and the first groove, the sealing between the sealing ring and the outer shell is increased, thereby preventing oil from leaking out of the outer shell. Under the action of the second sealing ring and the second groove, the sealing between the sealing ring and the round rod is increased, preventing dust from entering the outer shell.

[0035] During use, the spline sleeve 12 is connected to the output device. After the transmission gear block 29 rotates, the transmission gear block 29 drives the spline sleeve 12 to rotate, thereby driving the output device to rotate. Under the action of the washer 293, the sealing between the cover 1, the transmission gear block 29 and the spline sleeve 12 is increased.

[0036] The remaining structure is the same as that in Example 1.
