Background

With the increasing mileage demand of heavy commercial vehicles, especially tractor users, for the long-term vehicle, and the limitation of the chassis layout space, the double-oil-tank structure is applied more and more. The lower oil discharge ports of the main and auxiliary oil tanks of the existing double-oil-tank series structure are connected through oil pipes, the main oil tank is provided with an oil quantity sensor, and a breather valve with certain opening pressure is arranged on the oil quantity sensor. In order to realize generalization, the auxiliary oil tank still has an oil quantity sensor mounting port, and a sensor port sealing cover is generally used for plugging and is provided with a vent hole directly communicated with the atmosphere to ensure the communication of the double oil tanks; practice is that when the fuel is filled too fully or the vehicle is parked on an uneven road surface, the lowest part of the vent hole of the oil immersion sensor opening sealing cover can be filled with fuel, and the fuel can flow out of the vent hole of the auxiliary fuel tank. Fuel waste is caused, and driving safety is endangered; when negative pressure which does not enable the air inlet of the breather valve to be opened is formed in the main oil tank, the oil height h1 of the main oil tank is larger than the oil height h2 of the auxiliary oil tank under the action of atmospheric pressure. When positive pressure which does not enable the opening pressure of the air outlet of the breather valve is formed in the main oil tank, the oil height h1 of the main oil tank is smaller than the oil height h2 of the auxiliary oil tank under the action of pressure difference. So that the liquid level corresponding to the fuel quantity sensor is inconsistent with the actual residual fuel quantity.
