DETAILED DESCRIPTION
[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0026] See also Figure 1 and Figure 2Now, a multi-oil-circuit switching bidirectional pump provided by the utility model is described. A multi-oil-circuit switching bidirectional pump comprises a bidirectional pump body 100, the bidirectional pump body 100 has a first oil port 101 and a second oil port 102, a first oil outlet pipeline 500 is provided on the first oil port 101, and a second oil outlet pipeline 600 is provided on the second oil port 102; a third one-way valve 510 is provided on the first oil outlet pipeline 500, and the third one-way valve 510 supplies oil liquid to flow outward from the first oil port 101; a fourth one-way valve 610 is provided on the second oil outlet pipeline 600, and the fourth one-way valve 610 supplies oil liquid to flow outward from the second oil port 102; a connecting oil circuit 700 is connected between the oil outlet end of the first oil outlet pipeline 500 and the oil outlet end of the second oil outlet pipeline 600, and an oil circuit switching one-way valve 710 is provided on the connecting oil circuit 700.
[0027] The utility model provides a multi-oil-circuit switching bidirectional pump. Compared with the prior art, the first oil port 101 of the bidirectional pump body 100 is connected to the first oil outlet pipeline 500, the second oil port 102 of the bidirectional pump body 100 is connected to the second oil outlet pipeline 600, the third one-way valve 510 on the first oil outlet pipeline 500 allows oil to flow outward from the first oil port 101, and the fourth one-way valve 610 on the second oil outlet pipeline 600 allows oil to flow outward from the second oil port 102. Among them, an oil circuit switching one-way valve 710 is provided on the connecting oil circuit 700 connecting the first oil outlet pipeline 500 and the second oil outlet pipeline 600.
[0028] When using the multi-oil-circuit switching bidirectional pump provided by the utility model, if the bidirectional pump body 100 supplies oil in the forward direction, the oil enters the second oil outlet pipeline 600, and the oil-circuit switching one-way valve 710 ensures that the oil in the second oil outlet pipeline 600 will not enter the first oil outlet pipeline 500. At this time, the oil is discharged outward through the second oil outlet pipeline 600 alone. If the bidirectional pump body 100 supplies oil in the reverse direction, the oil enters the first oil outlet pipeline 500, and the oil-circuit switching one-way valve 710 ensures that the oil in the first oil outlet pipeline 500 can enter the second oil outlet pipeline 600. At this time, the oil is discharged outward through the first oil outlet pipeline 500 and the second oil outlet pipeline 600 at the same time. A multi-oil-circuit switching bidirectional pump provided by the utility model can realize the switching of different numbers of oil circuits when the bidirectional pump supplies oil in the forward and reverse directions, thereby achieving the purpose of adjusting the oil supply. This solution does not require the addition of solenoid valves and hydraulic modules, has a low space occupancy rate, and does not require increased costs.
[0029] In addition, the first oil port 101 is connected to a first oil inlet pipeline 300, on which a first check valve 310 is provided, and the first check valve 310 supplies oil to flow toward the first oil port 101. The second oil port 102 is connected to a second oil inlet pipeline 400, on which a second check valve 410 is provided, and the second check valve 410 supplies oil to flow toward the second oil port 102.
[0030] When the two-way pump body 100 is supplying oil in the forward direction, the oil enters the two-way pump body 100 through the first oil inlet pipeline 300 and the first oil port 101, and then is discharged into the second oil outlet pipeline 600 through the second oil port 102. At this time, the second check valve 410 on the second oil inlet pipeline 400 blocks the oil, so that the oil does not enter the second oil inlet pipeline 400 and cause backflow. When the two-way pump body 100 is supplying oil in the reverse direction, the oil enters the two-way pump body 100 through the second oil inlet pipeline 400 and the second oil port 102, and then is discharged into the first oil outlet pipeline 500 through the first oil port 101. At this time, the first check valve 310 on the first oil inlet pipeline 300 blocks the oil, so that the oil does not enter the first oil inlet pipeline 300 and cause backflow.
[0031] In addition, the multi-oil switching bidirectional pump also includes a main oil supply pipeline 900, which is connected to an oil storage unit 200, a first oil inlet pipeline 300 and a second oil inlet pipeline 400 are connected in parallel to the main oil supply pipeline 900, and a filter unit 910 is arranged on the main oil supply pipeline 900.
[0032] Specifically, the filter unit 910 is a suction filter. The suction filter can use vacuum to make the liquid in the suspended oil pass through the filter cloth to separate the solid and particle impurities in the oil to ensure the purity of the oil entering the bidirectional pump body 100. The oil storage unit 200 is an oil storage tank of the oil pan. The oil pan closes the crankcase and forms an oil storage tank that can store oil, which is used to collect and store lubricating oil.
[0033] In another embodiment, see Figure 3 and Figure 4 The oil outlet end of the second oil outlet pipeline 600 is connected in parallel with a plurality of second branch oil outlet pipelines 620, and the connecting oil path 700 is respectively connected to the first oil outlet pipeline 500 and any second branch oil outlet pipeline 620. At this time, the fourth check valve 610 is located on the second oil outlet pipeline 600, while the two second branch oil outlet pipelines 620 are not provided with any check valve.
[0034] When this embodiment is adopted, if the two-way pump body 100 supplies oil in the forward direction, the oil of the oil storage unit 200 enters the two-way pump body 100 through the first oil inlet pipeline 300, and then enters the two second branch oil outlet pipelines 620 through the second oil outlet pipeline 600. The oil circuit switching check valve 710 ensures that the oil of the second oil outlet pipeline 600 will not enter the first oil outlet pipeline 500. At this time, the oil is discharged outward through the two second branch oil outlet pipes, a total of two oil outlet pipelines. If the two-way pump body 100 supplies oil in the reverse direction, the oil of the oil storage unit 200 enters the two-way pump body 100 through the second oil inlet pipeline 400, and then enters the first oil outlet pipeline 500. The oil circuit switching check valve 710 ensures that the oil of the first oil outlet pipeline 500 can enter any second branch oil outlet pipeline 620, and then enter the other second branch oil outlet pipeline 620. At this time, the oil is discharged to the outside simultaneously through the first oil outlet pipeline 500 and the two second branch oil outlet pipelines 620, which are three oil outlet pipelines in total.
[0035] Similarly, the second branch oil outlet pipeline 620 can also be set to multiple. In the forward oil supply state, multiple second branch oil outlet pipelines 620 discharge oil to the outside; in the reverse oil supply state, the first oil outlet pipeline 500 and multiple second branch oil outlet pipelines 620 discharge oil to the outside.
[0036] See also Figure 5 and Figure 6 , multiple first branch oil outlet pipelines 520 can also be connected in parallel at the oil outlet end of the first oil outlet pipeline 500, and the oil supply method is the same as the above method. At this time, the number of first branch oil outlet pipelines 520, second branch oil outlet pipelines 620 and connecting oil circuits 700 is the same, and the three are connected one by one. That is, in the forward oil supply state, only the second branch oil outlet pipeline 620 discharges oil, and in the reverse oil supply state, the first branch oil outlet pipeline 520 and the second branch oil outlet pipeline 620 can discharge oil at the same time.
[0037] The first oil outlet pipeline 500 and the second branch oil outlet pipeline 620 are both provided with a throttle hole 800, which adjusts the oil pressure by changing the flow rate of the oil to meet different oil supply requirements. The throttle holes 800 provided in the first oil outlet pipeline 500 and the second branch oil outlet pipeline 620 can be designed to have different apertures, thereby changing the oil flow rate and oil pressure of the first oil outlet pipeline 500 and the second branch oil outlet pipeline 620.
[0038] Based on the same inventive concept, the utility model also provides a vehicle, which uses the above-mentioned multi-oil circuit switching bidirectional pump. The bidirectional pump adopts an electronic oil pump, and variable oil supply is achieved through the on-board computer controller to alternate forward and reverse rotation, maintain time and speed. Regardless of forward rotation or reverse rotation, the working oil circuit can be continuously supplied with oil, which solves the problem that the oil pump cannot supply oil when it is reversed (reversing condition).
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
