Description

Ventilation structure of split type oil storage kettle

Technical Field

The utility model relates to an automobile brake system, concretely relates to ventilation structure of split type oil storage kettle.

Background

The brake system is one of the most important systems of the automobile, the brake oil storage pot belongs to one of key components of the automobile brake system, and the reasonability and the practicability of the design directly influence the safety and the reliability of the whole automobile. Because the arrangement of a vehicle engine compartment is limited, more and more vehicle braking systems adopt split type oil tanks, namely two oil tanks are adopted for storing oil, as shown in figure 1, a far end oil tank (1) and a main cylinder oil tank (3) are communicated through a connecting hose (2), and the oil tanks arranged in the form have small pipe diameter and bend angles due to the fact that the connecting hose is small in pipe diameter, when brake fluid is manually filled, the oil in the far end oil tank and the air in the main cylinder oil tank need to simultaneously pass through the connecting hose, and the directions of the oil tanks and the air are opposite, so that the connecting hose is easily blocked, and the brake fluid is not smoothly filled.

Therefore, the ventilation structure of the oil storage pot is required to be developed on the premise of not changing the arrangement structure of the oil pot and the connecting hose, so that the ventilation structure of the oil storage pot is smooth when brake fluid is manually filled.

CN205770181U discloses "a ventilation system for an oil storage tank", in which a ventilation pipeline has two paths, one path can discharge gas by manual control, and the other path can discharge gas passively when the pressure in the oil storage tank is too high, so as to meet the requirement of discharging gas in the oil storage tank under different conditions in the prior art. The oil storage tank ventilation system comprises a ventilation pipeline, and the ventilation pipeline is communicated with the outside; an electric flashboard switch and a pressure relief branch are arranged in the ventilation pipeline; the electric flashboard switch can be used for switching on and off the communication between the oil storage tank and the outside; the pressure relief branch is preset with a pressure relief value, and the pressure relief value is smaller than the maximum tolerance of the oil storage tank; the pressure relief branch can be opened when the pressure in the oil storage tank exceeds the preset pressure relief pressure value, so that the pressure relief branch becomes a passage. This is, of course, a beneficial attempt in the art.
