Anti-flameout fuel tank for off-road vehicle

Abstract

The invention relates to an anti-flameout fuel tank for an off-road vehicle. The anti-flameout fuel tank comprises a tank body assembly; the tank body assembly comprises an oil tank body, a front endcover, a rear end cover and partition plates; the oil tank body is further provided with an oil filling pipe and a breather pipe; the partition plates comprise a front partition plate and a rear partition plate; the front partition plate and the rear partition plate divide an inner cavity of the oil tank body into a front cavity, a middle cavity and a rear cavity; and oil through holes are formedin the front partition plate and the rear partition plate in a penetrating manner. The fuel tank further comprises an anti-flameout device, and the anti-flameout device comprises a one-way valve assembly and an oil taking pipe. The one-way valve assembly is installed on the lower portion of the rear partition plate in a matched mode and comprises a valve body, a valve block, a blocking piece, a valve body installation flange and a sealing ring. The anti-flameout fuel tank is reasonable and compact in structural design, capable of guaranteeing sufficient fuel supply when the automobile goes down a long slope and climbs up the long slope, capable of preventing flameout of the automobile caused by fuel supply, safe and reliable to use and capable of effectively meeting the off-road performance of the automobile.

Description

technical field [0001] The invention relates to the technical field of vehicle fuel tanks, in particular to a flameout-proof fuel tank for off-road vehicles. Background technique [0002] With the development of my country's automobile industry, the performance requirements of auto parts are getting higher and higher. Military off-road vehicles need to meet the driving conditions under various harsh working conditions, and the performance of the power system is very important; Sufficient and reliable fuel also puts forward higher requirements on the performance of the fuel tank. When some existing military off-road vehicles go uphill or downhill, because the fuel tank does not have an anti-flame device, it will cause insufficient fuel supply, which will affect the climbing power of the car. [0003] In the Chinese patent No. CN201621310561.2, a flameout-proof fuel tank for loaders is disclosed, which includes a fuel tank body, and the fuel tank body specifically includes a b...

AI Technical Summary

Problems solved by technology

At the same time, by changing the position of the oil suction pipe, the technical solution realizes that the oil suction pipe is always at the place with the most fuel during the uphill and downhill process of the loading vehicle, but this solution also needs to increase the rotation and fixing device of the oil suction pipe, which is not included in this technical solution. Describe how to make the oil suction pipe rotate according to the road conditions of the vehicle, and the oil suction pipe needs to resist the impact force brought by the fuel during the running of the vehicle. If a rotating fixing device is added, the reliability of the rotating device is difficult to guarantee
