Description

Technical Field

[0001] This utility model relates to the field of power steering pump technology, and more specifically, to a power steering pump for automobiles with lubrication function. Background Technology

[0002] The power steering pump, also known as a 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 then converts the hydraulic energy into mechanical energy through the hydraulic oil output by the oil pump, thereby reducing the driver's operating intensity and improving the overall vehicle maneuverability. It mainly consists of a standard double-acting vane pump, a flow control valve, and a pressure relief valve. The double-acting vane pump provides high-pressure oil, the flow control valve ensures that the steering pump outputs a flow rate suitable for the vehicle's needs, and the pressure relief valve controls the maximum output pressure of the steering pump.

[0003] A search revealed that Chinese utility model patent application number CN202420299986.6 discloses a power steering pump with lubrication function, including a power steering pump body and a lubrication mechanism. The power steering pump body has a mounting groove at one end of the rotor shaft, and a circular array of connecting holes is formed on the mounting groove. The lubrication mechanism includes an oil reservoir installed inside the mounting groove, and connecting flanges are fixedly connected to both ends of the oil reservoir.

[0004] In use, the pump body has a mounting groove at the end and a connecting hole on the inner wall of the groove. The oil reservoir is fixed to the outer surface of the pump rotor shaft through the connecting hole and the connecting flange. The connecting flange and the oil seal bearing form a sealed space, which is filled with lubricating material. This allows the connection between the rotor shaft and the outer surface of the pump to be lubricated when the pump is working. However, the two oil injection pipes are at the same height, making it difficult for the oil inside the pump to drain from the sealed space formed by the connecting flange and the oil seal bearing. This also hinders the circulation of oil within the sealed space, resulting in poor heat dissipation for the pump. In addition, the pump body is mounted on multiple screws. Since the screws are located between the two connecting flanges, the limited space between them makes it difficult to place the socket wrench on the screws and to use an electric wrench for disassembly and assembly. The screws need to be manually tightened by hand, resulting in low disassembly efficiency. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides a power steering pump with lubrication function to solve the technical problems mentioned in the background art, where the two oil injection pipes are located at the same height, the oil inside the power steering pump enters into the sealed space formed by the connecting flange and the oil seal bearing, which makes it difficult to discharge the oil and facilitates the circulation of oil within the sealed space, resulting in poor heat dissipation for the power steering pump.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a power steering pump with lubrication function, comprising a power steering pump body, an oil injection pipe connected to the power steering pump body, a first oil outlet pipe connected to the bottom end of the power steering pump body, a lubrication cover mounted on the side end of the power steering pump body by multiple first screws, a sealing gasket provided between the lubrication cover and the power steering pump body, the oil injection pipe inserted into the interior of the lubrication cover, an oil seal bearing connected to the lubrication cover, the oil seal bearing sleeved on the outside of the rotor shaft of the power steering pump body, a second oil outlet pipe connected to the bottom end of the lubrication cover, a connecting pipe connected to the first oil outlet pipe, the connecting pipe connected to the second oil outlet pipe through a pipe connector, facilitating oil flow inside the lubrication cover, facilitating the replacement of the lubrication cover, facilitating the flow of oil with a certain temperature inside the power steering pump body into the interior of the lubrication cover, facilitating oil heat dissipation, and ensuring heat dissipation effect.

[0009] The present invention is further configured such that multiple heat-conducting plates are fixedly connected to the lubrication cover, and the two ends of the multiple heat-conducting plates extend to the inside and outside of the lubrication cover respectively, so as to facilitate the heat conduction from the inside of the lubrication cover.

[0010] The present invention is further configured such that a fixed cover is installed on the side end of the lubrication cover, and a rotating tube is rotatably connected to the fixed cover. The rotating tube is sleeved on the outside of the rotor shaft of the booster pump body. Multiple fan blades are fixedly connected to the outer wall of the part of the rotating tube inside the fixed cover to improve the heat dissipation effect.

[0011] The present invention is further configured such that a second screw that mates with the rotor shaft of the booster pump body is threaded onto the rotating tube, which facilitates fixing the rotating tube onto the rotor shaft of the booster pump body, and facilitates the rotor shaft of the booster pump body to drive the rotating tube to rotate.

[0012] The present invention is further configured such that a plurality of first vents are provided at the end of the fixed cover away from the lubrication cover, and a plurality of second vents are uniformly provided on the outer side wall of the fixed cover, so as to facilitate the circulation of air inside the fixed cover.

[0013] The present invention is further configured such that a filter screen is fixedly connected inside each of the plurality of first vents and the plurality of second vents to prevent the air from entering the interior of the fixed cover.

[0014] The present invention is further configured such that the side end of the lubrication cover is provided with multiple countersunk grooves, and each of the multiple countersunk grooves is provided with a through groove.

The multiple mounting holes are respectively connected to the multiple grooves, which facilitates the passage of bolts and facilitates the connection of the lubrication cover to the external structure by bolts.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a power steering pump with lubrication function, which has the following beneficial effects:

[0018] 1. A second oil outlet pipe is connected to the bottom of the lubrication cover. The second oil outlet pipe is connected to the connecting pipe and the first oil outlet pipe through a pipe connector. The oil inside the booster pump body is transported to the inside of the lubrication cover through the oil inlet pipe. The oil inside the lubrication cover lubricates the connection between the rotor shaft and the outer surface of the booster pump. The oil entering the lubrication cover enters the inside of the first oil outlet pipe through the second oil outlet pipe, the pipe connector and the connecting pipe, and is discharged through the first oil outlet pipe. This allows the oil to circulate inside the lubrication cover, facilitating the flow of oil with a certain temperature inside the booster pump body into the inside of the lubrication cover, which is conducive to the cooling of the oil and ensures the cooling effect.

[0019] 2. By setting up multiple heat-conducting plates, the temperature of the oil circulating inside the lubrication cover is transferred to multiple heat-conducting plates. At the same time, the rotor shaft of the booster pump body drives the rotating tube and multiple fan blades to rotate. The rotation of multiple fan blades causes air to circulate around the multiple heat-conducting plates located outside the lubrication cover, cooling the multiple heat-conducting plates. This facilitates the cooling of the oil inside the lubrication cover and improves the heat dissipation effect of the booster pump body.

[0020] 3. Because multiple countersunk grooves and multiple through grooves are provided on one side of the lubrication cover, it is easy for the first screw to pass through the inside of the countersunk grooves and through grooves and be screwed onto the booster pump body, thus fixing the lubrication cover to the booster pump body. Since the screw head of the first screw is exposed, it is easy for people to use an electric wrench to tighten the first screw, which facilitates quick assembly and disassembly and improves the efficiency of assembly and disassembly.

[0030] Please see Figures 1-5A power steering pump with lubrication function includes a power steering pump body 1, an oil injection pipe 2 connected to the power steering pump body 1, a first oil outlet pipe 3 connected to the bottom end of the power steering pump body 1, a lubrication cover 5 installed on the side end of the power steering pump body 1 by multiple first screws 4, a sealing gasket 6 provided between the lubrication cover 5 and the power steering pump body 1, the oil injection pipe 2 being inserted into the interior of the lubrication cover 5, an oil seal bearing 7 connected to the lubrication cover 5, the oil seal bearing 7 being sleeved on the outside of the rotor shaft of the power steering pump body 1, a second oil outlet pipe 8 connected to the bottom end of the lubrication cover 5, a connecting pipe 9 connected to the first oil outlet pipe 3, and the connecting pipe 9 being connected to the second oil outlet pipe 8 through a pipe connector 10.

[0031] Specifically, a second oil outlet pipe 8 is connected to the bottom of the lubrication cover 5. The second oil outlet pipe 8 is connected to the connecting pipe 9 and the first oil outlet pipe 3 through the pipe connector 10. The oil inside the booster pump body 1 is transported to the inside of the lubrication cover 5 through the oil inlet pipe. The oil inside the lubrication cover 5 lubricates the connection between the rotor shaft and the outer surface of the booster pump body 1. The oil entering the lubrication cover 5 enters the inside of the first oil outlet pipe 3 through the second oil outlet pipe 8, the pipe connector 10 and the connecting pipe 9, and is discharged through the first oil outlet pipe 3. This allows the oil to circulate inside the lubrication cover 5, facilitating the flow of oil with a certain temperature inside the booster pump body 1 into the inside of the lubrication cover 5, which helps to dissipate heat from the oil and ensures the heat dissipation effect.

[0032] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 Multiple heat-conducting plates 11 are fixedly connected to the lubrication cover 5. The two ends of the multiple heat-conducting plates 11 extend to the inside and outside of the lubrication cover 5, respectively, to facilitate the conduction of heat from inside the lubrication cover 5. A fixed cover 12 is installed on the side of the lubrication cover 5. A rotating tube 13 is rotatably connected to the fixed cover 12. The rotating tube 13 is sleeved on the outside of the rotor shaft of the booster pump body 1. Multiple fan blades 14 are fixedly connected to the outer wall of the part of the rotating tube 13 inside the fixed cover 12. A threaded connection is made to the rotating tube 13 to match the rotor shaft of the booster pump body 1. The second screw 15 is used to fix the rotating tube 13 to the rotor shaft of the booster pump body 1, so that the rotor shaft of the booster pump body 1 can drive the rotating tube 13 to rotate. The end of the fixed cover 12 away from the lubrication cover 5 is provided with multiple first vents 16. Multiple second vents 17 are evenly provided on the outer wall of the fixed cover 12 to facilitate the flow of air inside the fixed cover 12. Filter plates 18 are fixedly connected inside the multiple first vents 16 and multiple second vents 17 to prevent air from entering the interior of the fixed cover 12.

[0033] Specifically, by setting up a number of heat-conducting plates 11, the temperature of the oil circulating inside the lubrication cover 5 is transferred to the multiple heat-conducting plates 11. At the same time, the rotor shaft of the booster pump body 1 drives the rotating tube 13 and multiple fan blades 14 to rotate. The rotation of the multiple fan blades 14 causes air to circulate around the multiple heat-conducting plates 11 located outside the lubrication cover 5, thereby cooling the multiple heat-conducting plates 11. This facilitates the cooling of the oil inside the lubrication cover 5 and improves the heat dissipation effect of the booster pump body 1.

[0034] Please see Figure 1 , Figure 3 and Figure 4 The lubrication cover 5 has multiple countersunk grooves 19 on its side, and each countersunk groove 19 has a through groove 20 inside. Multiple first screws 4 pass through the through grooves 20 respectively. Since the screw head of the first screw 4 is located on one side of the lubrication cover 5, it is convenient for people to use an electric wrench to turn the first screw 4, which facilitates the disassembly of the lubrication cover 5. Multiple grooves 21 are evenly arranged on the outer wall of the lubrication cover 5. Multiple mounting holes 22 are provided on the side of the lubrication cover 5. The mounting holes 22 are connected to the grooves 21 respectively, which facilitates the passage of bolts and makes it easy to connect the lubrication cover 5 to the external structure by bolts.

[0035] Specifically, since multiple countersunk grooves 19 and multiple through grooves 20 are provided on one side of the lubrication cover 5, the first screw 4 can pass through the inside of the countersunk grooves 19 and through grooves 20 and be screwed onto the booster pump body 1, thus fixing the lubrication cover 5 onto the booster pump body 1. Since the screw head of the first screw 4 is exposed, it is convenient for people to use an electric wrench to turn the first screw 4, which facilitates quick disassembly and assembly, and improves the efficiency of disassembly and assembly.

[0036] In summary, when using the overall equipment:

[0037] Both the first oil outlet pipe 3 and the oil injection pipe 2 are connected to the oil outlet end of the booster pump body 1. During the operation of the booster pump body 1, part of the booster oil inside the booster pump body 1 is squeezed into the first oil outlet pipe 3, and part is squeezed into the lubrication cover 5. The oil inside the lubrication cover 5 lubricates the connection between the rotor shaft and the outer surface of the booster pump body 1. The oil entering the lubrication cover 5 enters the first oil outlet pipe 3 through the second oil outlet pipe 8, the pipe connector 10, and the connecting pipe 9, and is discharged through the first oil outlet pipe 3. Through the provision of multiple heat-conducting plates 11, the temperature of the oil circulating inside the lubrication cover 5 is transferred to multiple heat-conducting plates 11. At the same time, the rotor shaft of the booster pump body 1 drives the rotating pipe 13 and multiple fan blades 14 to rotate. The rotation of multiple fan blades 14 causes air to circulate around the multiple heat-conducting plates 11 located outside the lubrication cover 5, thereby cooling the multiple heat-conducting plates 11.
