Oil storage tank, oil shielding component of oil storage tank and vehicle with oil storage tank

Abstract

The invention discloses an oil storage tank, an oil shielding component of the oil storage tank and a vehicle with the oil storage tank. The oil storage tank comprises a tank body and a tank cover; a tank opening, an oil outlet and an oil return opening are formed in the tank body; the tank cover comprises an inner cover body, an oil shielding piece and an outer cover body; the inner cover body covers the tank opening; a first vent hole is formed in the inner cover body; the oil shielding piece is arranged under the first vent hole; the outer cover body covers the inner cover body; and a flowing passage is formed at the matched part of the inner cover body and the outer cover body. The oil storage tank has the advantages that the inside and outside pressures of the oil storage tank can be balanced and the good sealing performance of the oil storage tank can also be guaranteed.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to an oil storage tank, an oil retaining assembly of the oil storage tank and a vehicle with the oil storage tank. Background technique [0002] In related technologies, the steering system of trucks usually adopts hydraulic power assist. The oil storage tank in the hydraulic system is used to store oil to supply oil to the oil pump and system in time. The oil storage tank is equipped with a filter structure to filter impurities in the oil. To ensure the cleanliness of the oil, in addition, it also has the function of heat dissipation and lowering the temperature of the oil. [0003] The existing oil storage tank adopts the following structure: a primary filter is provided under the tank cover of the oil storage tank, and a filter element assembly opposite to the primary filter and located below the primary filter is provided on the bottom wall of the oil storage tank to enter th...

AI Technical Summary

Problems solved by technology

[0005] 1) If the fit between the tank cover and the tank body is too tight, the normal air pressure in the tank cannot be maintained, and if the fit between the tank cover and the tank body is too loose, the tightness of the tank cannot be guaranteed, resulting in the accumulation of oil on the tank cover;

[0006] 2) The pressure loss of the filter element assembly of the oil storage tank is relatively large, which affects the oil supply to the oil pump;

[0007] 3) The quality of the oil storage tank is large, the cost is high, and the manufacturing process is complicated;

[0008] 4) The liquid level of the oil storage tank should be measured indirectly through the oil dipstick assembly, and the liquid level cannot be directly checked
