The invention provides an oil-way switching device, an oil-way control system and a vehicle. The oil-way switching device comprises a valve body, a valve element, a driving part and an emergency brakepart, wherein a flow guide channel is formed in the valve body; the valve element is located in the valve body and is used for switching connected and disconnected states of the flow guide channel; the driving part is arranged on the valve body, is connected to the valve element and is used for driving the valve element to move; and the emergency brake part is arranged on the valve body, is connected to the valve element, and can drive the valve element to move when the driving part breaks down so as to change the connected state of the oil-way switching device. According to the oil-way switching device, the emergency brake part with an emergency unauthorized function is arranged on the valve body, when the driving part breaks down or has other emergency situations, the emergency brake part is directly used for driving the valve element to move, the safety performance of the oil-way switching device is improved, and normal use of the oil-way switching device can be guaranteed.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an oil circuit switching device, an oil circuit control system and a vehicle. Background technique [0002] At present, due to the advantages of good economy, high reliability, and high power, most trucks use diesel engines as the vehicle power. However, in some extremely cold regions, due to the low temperature, diesel engines often have difficulty in starting, and the low-temperature waxing of fuel blocks the fuel pipeline, making the vehicle unusable. [0003] High-grade fuel is cheap, but has a high waxing point, which is inconvenient to use in cold regions. Low-grade fuel is not easy to wax, but the price is high. In order to solve the problem of vehicles working in cold regions, double-marked fuel tanks are usually used, the main fuel tank is filled with high-marked fuel, and the auxiliary fuel tank is filled with low-marked fuel. When starting, use the low-...
