Abstract

The invention relates to the field of vehicle oil supply systems, in particular to a mechanical automatic control oil supply system for a vehicle. The system comprises an oil tank, an oil supply line, a fuel oil control valve and a mechanical sensing control device. The fuel oil control valve comprises a valve body and a valve element. The oil supply line comprises an oil pump, oil suction pipes and an oil conveying pipe. The fuel oil control valve is arranged at the connecting position of the oil conveying pipe and the oil suction pipes. One end of the first oil suction pipe is connected to the side, close to a vehicle head or vehicle tail, of the inside of the valve body, and the other end of the first oil suction pipe is arranged at the bottom of the side, close to the vehicle head or vehicle tail, of the inside of the oil tank. One end of the second oil suction pipe is connected to the side, opposite to the first oil suction pipe, of the inside of the valve body, and the other end of the second oil suction pipe is arranged at the bottom of the side, opposite to the first oil suction pipe, of the inside of the oil tank. The mechanical sensing control device comprises a connecting rod, a rocker arm, a support and a sensing hammer. The valve element slides in the valve body. One end of the connecting rod is connected with the valve element, and the other end of the connecting rod is hinged to the upper portion of the rocker arm. The middle part of the rocker arm is hinged to the support. The lower portion of the rocker arm is connected with the sensing hammer.

Description

technical field [0001] The invention relates to the field of vehicle fuel supply systems, in particular to a vehicle mechanical automatic control fuel supply system. Background technique [0002] The fuel supply system is an important guarantee for the normal operation of a vehicle. When the vehicle goes uphill or downhill or during emergency braking and rapid acceleration, the fuel in the fuel tank will rush to one end of the fuel tank under the action of gravity and acceleration, resulting in When the liquid level drops, when the amount of fuel in the fuel tank is small, it may cause insufficient fuel supply or fuel cut-off, which will cause the vehicle to turn off and stop when going up and down slopes, causing certain safety hazards. This invention is the design invention that solves this problem. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vehicle mechanical automatic control fuel supply system to sol...
