Description

Technical Field

[0001] The utility model relates to the technical field of engine oil supply, and more specifically, to an engine oil supply device with double oil pumps. Background Art

[0002] When a vehicle climbs a slope, the oil in the oil pan is affected by gravity to form a local low oil level. Since the oil inlet of a traditional oil pump is set in the deep oil area of ​​the oil pan, once the local low oil level phenomenon occurs, it is difficult for the oil pump to suck oil, which can easily lead to the problem of the entire machine being scrapped due to lack of oil and severe wear.

[0003] The existing patent with publication number: CN 111022146 A discloses an anti-tilt oil pan, in which a tilt sensor is installed on the engine, and a two-position three-way solenoid valve, an oil suction pipe, a defoaming plate and other devices are installed in the oil pan. When the engine tilts, the tilt sensor can transmit the engine tilt angle signal to the ECU, and then the ECU determines and controls the two-position three-way solenoid valve to adopt different oil suction strategies to ensure that the engine can form a good oil return cycle under various tilt angle conditions.

[0004] In the existing oil pan, an inclination sensor is used to sense and the ECU controls a three-way solenoid valve to suck oil from different positions. Although this can prevent the problem of oil being sucked out, the electronic control method is prone to failure. At the same time, in the existing oil supply device, its three-way solenoid valve, oil suction pump and other components are mostly installed in the oil pan. This layout makes it troublesome to disassemble and assemble the oil pan, and various pipelines need to be removed to remove the oil pan, which is not conducive to disassembly and maintenance.

[0005] Therefore, it is necessary to design an engine oil supply device with dual oil pumps to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an engine oil supply device with a dual oil pump in view of the above-mentioned deficiencies in the prior art, which can ensure sufficient oil and prevent it from being sucked empty, effectively reduce manufacturing costs, and facilitate disassembly and maintenance.

[0007] The technical solution of the utility model is as follows: an engine oil supply device with a dual oil pump, comprising a main oil pump and a subsidiary oil pump, the main oil pump and the subsidiary oil pump being integrally mounted on a mounting plate, the mounting plate being detachably connected to an engine body, the oil supply pipe corresponding to the main oil pump being connected to the engine body, the oil suction pipe corresponding to the main oil pump extending to the bottom of a deep oil area of ​​an oil pan, a conical cover being provided at the bottom of the oil suction pipe, a filter being detachably installed in the conical cover, the oil inlet pipe corresponding to the subsidiary oil pump extending to the bottom of a shallow oil area of ​​the oil pan, a reinforcement assembly being provided between the oil inlet pipe corresponding to the subsidiary oil pump and the engine body, the oil outlet pipe corresponding to the subsidiary oil pump extending into the deep oil area of ​​the oil pan, and the bottom of the oil outlet pipe being arranged toward the top of the conical cover.

[0008] As a further improvement, the mounting plate and the reinforcement assembly are connected to the engine body via fastening bolts.

[0009] Furthermore, the reinforcement component includes a U-shaped seat, the oil inlet pipe corresponding to the auxiliary oil pump is clamped in the U-shaped seat, and connecting plates are provided at both ends of the opening of the U-shaped seat, and the connecting plates are connected to the engine body by fastening bolts.

[0010] Furthermore, the inner cavity of the U-shaped seat is a conical cavity with a narrow upper end and a wide lower end.

[0011] Furthermore, a plurality of limiting platforms are provided at the bottom of the inner wall of the conical cover, and the filter is clamped in the conical cover at the top of the limiting platform.

[0012] Furthermore, the filter screen is a stainless steel screen, and a pull ring is provided in the middle of the filter screen.

[0013] Furthermore, the distance from the bottom surface of the conical cover to the bottom surface of the oil pan, and the distance from the end of the oil inlet pipe corresponding to the auxiliary oil pump to the bottom surface of the oil pan are both 5 mm to 10 mm.

[0014] Beneficial Effects

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. The engine oil supply device of the utility model is provided with two oil pumps, a main oil pump and an auxiliary oil pump, in the engine oil pan.

At the same time, the auxiliary oil pump pumps oil in real time, so that the oil keeps flowing in the oil pan, which can effectively ensure the flow performance of the oil.

[0017] 2. The engine oil supply device of the utility model has a main oil pump and an auxiliary oil pump which are integrated and mounted on a mounting plate and connected to the engine body, and an oil inlet pipe corresponding to the auxiliary oil pump is also connected to the engine body, so that all components of the oil supply device are separated from the oil pan; during maintenance, the oil pan can be directly removed without linking the oil supply device, and disassembly and assembly and maintenance are very convenient.
