Description

Technical Field

[0001] The utility model relates to an automobile power steering pump, more particularly to an oil storage pot structure of the automobile power steering pump. Background Art

[0002] The automobile power steering pump is also called the power steering pump. The power steering pump is the power source of the hydraulic power steering system. It uses the engine as a transmission medium to convert mechanical energy into hydraulic energy. The steering gear converts hydraulic energy into mechanical energy through the hydraulic oil output by the oil pump, thereby reducing the driver's operating intensity and improving the maneuverability of the entire vehicle.

[0003] When the automobile power steering pump is working, metal chips will continuously be generated on the friction surface of the moving pair during the operation of the steering gear and the power steering pump. Therefore, in the prior art, there is a utility model patent with publication number CN221610336U, entitled "Magnetic Chip Absorption Device for Automobile Power Steering Pump Oil Storage Pot", which discloses that the generated metal chips are removed by setting a filter screen and a magnetic rod. When the liquid flows at high speed, the filter screen can effectively confine the metal chips, thereby preventing the metal chips on the magnetic rod from entering the oil outlet with the high-speed liquid. However, although the above method avoids the problem of metal chips entering the oil outlet, the metal chips washed off the magnetic rod still remain in the filter screen and will be re-absorbed by the magnetic rod. After a layer of metal chips is covered, the adsorption capacity of the magnetic rod will naturally be reduced. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an automobile power steering pump oil reservoir structure whose adsorption capacity is not easily reduced.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a car power steering pump oil storage pot structure, comprising a pot body, a pot cover, a magnetic rod and a filter screen, wherein the pot cover is fixedly mounted on the upper end of the pot body, the filter screen is coaxially passed through the pot body, the lower end of the pot body is provided with an oil inlet, the side wall of the pot body is provided with an oil outlet, the upper end of the magnetic rod is coaxially fixed to the lower end of the pot cover, and the utility model is characterized in that a magnetic disk is coaxially fixed to the lower end of the pot cover, a scraping disk is coaxially sleeved on the magnetic rod, and the scraping disk slides up and down on the magnetic rod, and is driven by oil to slide upward to scrape metal chips from the magnetic rod and then push them to the magnetic disk.

[0006] As a further improvement of the present invention, a storage ring is coaxially fixed to the upper end of the filter screen, the upper end of the storage ring is coaxially fixed to the lower end of the pot lid, and the magnetic disk is accommodated in the storage ring to form a groove structure for accommodating metal grinding chips through the lower end surface of the magnetic disk and the inner side wall of the storage ring.

[0007] As a further improvement of the present invention, the scraper is made of engineering plastic, and the outer side wall of the scraper is provided with a circular chamfer.

[0008] As a further improvement of the present invention, a spring is coaxially sleeved on the magnetic rod, the upper end of the spring is fixed to the magnetic disk, and the lower end of the spring is fixed to the upper end surface of the scraper.

[0009] As a further improvement of the present invention, a limit plate is coaxially fixed to the lower end of the magnetic rod so as to abut against the lower end surface of the scraper disc to limit the position when the scraper disc descends to the lowest point.

[0010] As a further improvement of the present invention, a scraping hole is opened at the center of the scraping disc, and a plurality of bristles distributed in a circle are fixed to the hole wall of the scraping hole. Several of the bristles are coaxial with the scraping hole. When the scraping disc is put on the magnetic rod, the ends of the bristles are against the magnetic rod.

[0011] The beneficial effect of the present invention is that, by arranging the pot body, pot cover, magnetic rod and filter screen, the same oil storage pot structure as in the prior art can be constituted. Furthermore, by arranging the magnetic disk and scraper plate, it is possible to use the high-speed oil rushing in from the oil inlet to push the scraper plate to rise during operation. In the process of the scraper plate rising, the metal chips on the magnetic rod will be scraped off and then pushed to the lower end surface of the magnetic disk. In this way, the centralized storage of metal chips can be effectively achieved through the adsorption of the magnetic disk, thereby keeping the surface of the magnetic rod smooth and clean, thereby maintaining the adsorption capacity of the magnetic rod.

[0014] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figures 1 to 2As shown, an automobile power steering pump oil storage pot structure of the present embodiment comprises a pot body 1, a pot cover 2, a magnetic rod 3 and a filter 4, the pot cover 2 is fixedly mounted on the upper end of the pot body 1, the filter 4 is coaxially penetrated in the pot body 1, the lower end of the pot body 1 is provided with an oil inlet 5, the side wall of the pot body 1 is provided with an oil outlet 6, the upper end of the magnetic rod 3 is coaxially fixed to the lower end of the pot cover 2, and is characterized in that: a magnetic disk 7 is coaxially fixed to the lower end of the pot cover 2, a scraper 8 is coaxially sleeved on the magnetic rod 3, the scraper 8 slides up and down on the magnetic rod 3, and is driven by the oil to slide upward to scrape metal chips from the magnetic rod 3 and then push them to the magnetic disk 7. In the process of using the oil storage pot structure of the present embodiment , you only need to connect the oil storage pot to the external power steering pump, and then start working. During the operation, the power steering pump will inject high-speed oil into the oil inlet 5, and the impact of the high-speed oil will drive the scraper 8 to move upward, so that the scraper 8 will scrape off the metal chips on the magnetic rod 3, and then push it to the disk 7. Through the adsorption effect of the disk 7, this part of the metal chips will be retained. When stopping working, the scraper 8 will move downward and reset, and the metal chips will be continuously stored on the lower end surface of the disk 7. Compared with the method in the prior art, the centralized storage of metal chips can be achieved, and the surface of the magnetic rod 3 can be effectively kept smooth, thereby maintaining the adsorption force of the magnetic rod 3.

[0016] As a specific embodiment of the improvement, a storage ring 41 is coaxially fixed to the upper end of the filter screen 4, and the upper end of the storage ring 41 is coaxially fixed to the lower end of the pot cover 2. The magnetic disk 7 is accommodated in the storage ring 41, so that a groove structure for accommodating metal chips is formed by the lower end face of the magnetic disk 7 and the inner side wall of the storage ring 41. By setting the storage ring 41, a groove structure can be formed, which can better store metal chips and further increase the retention effect of the adsorption force of the magnetic rod 3.

[0017] As a specific embodiment of the improvement, the scraper 8 is made of engineering plastic, and the outer wall of the scraper 8 is provided with a circular chamfer. By making the scraper 8 of engineering plastic, on the one hand, the influence of magnetic force can be avoided, and on the other hand, the weight is lighter and more corrosion-resistant. The outer wall of the scraper 8 is provided with a circular chamfer, so that there is a better sliding effect between the scraper 8 and the inner wall of the filter 4.

[0018] As a specific embodiment of the improvement, a spring is coaxially sleeved on the magnetic rod 3, the upper end of the spring is fixed to the magnetic disk 7, and the lower end is fixed to the upper end surface of the scraper 8. Due to the high density of the oil, the scraper 8 is reset relatively slowly after the work is completed. In this way, the setting of the spring can effectively accelerate the reset of the scraper 8.

[0019] As an improved specific embodiment, a limit plate 31 is coaxially fixed to the lower end of the magnetic rod 3 to limit the scraper 8 against the lower end surface of the scraper 8 when the scraper 8 drops to the lowest point. By setting the limit plate 31, the problem of the scraper 8 falling off the magnetic rod 3 due to excessive drop can be effectively avoided.

[0020] As an improved specific embodiment, a scraping hole 81 is opened at the center of the scraping disk 8, and a plurality of circumferentially distributed bristles 82 are fixed to the hole wall of the scraping hole 81. Several of the bristles 82 are coaxial with the scraping hole 81. When the scraping disk 8 is put on the magnetic rod 3, the ends of the bristles 82 are against the magnetic rod 3. Through the arrangement of the scraping hole 81 and the bristles 82, the scraping disk 8 can effectively brush the metal chips from the outer wall of the magnetic rod through the bristles 82 when the magnetic rod 3 rises, and at the same time, the wear between the scraping disk 8 and the magnetic rod 3 can also be greatly reduced.

[0021] In summary, the automobile power steering pump oil reservoir structure of this embodiment can effectively realize a space for centralized storage of metal grinding chips by arranging a magnetic disk 7 at the lower end of the pot cover 2, and then, by arranging a scraper 8, the metal grinding chips adsorbed on the magnetic rod 3 can be centralized and stored in the space, thereby effectively maintaining the adsorption force of the magnetic rod 3.

[0022] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
