Abstract
The utility model relates to an oil inlet and return pipe assembly for a fuel tank of a cargo truck. The oil inlet and return pipe assembly comprises an oil inlet and return pipe and an oil pipe base, wherein the oil inlet end of the oil inlet and return pipe is provided with a filter screen, the oil pipe base is columnar and is axially provided with a through screwed hole, the middle section of the external part of the oil pipe base is provided with an annular boss, the boss end of the annular boss is arranged outside the fuel tank and is connected with a banjo union through a tee bolt, and the other end of the oil pipe base is arranged outside the fuel tank and is connected with the other end of the oil inlet and return pipe. The oil inlet and return pipe assembly provided by the utility model solves the problem that a fuel tank assembly needs to be replaced due to the damage of the oil inlet and return pipe assembly. The requirement of different engines on the pipe diameter of the oil inlet and return pipe can be met through the adjustment of the inner diameter of the banjo union, and the universality of a fuel tank body is improved. Due to the adoption of the banjo union, the oil pipe can be conveniently and freely rotated, and the oil obstruction of the oil pipe can be reduced; and due to the structural design that the oil inlet and return pipe is separated from an oil inlet and return joint, an oil inlet and return opening can be conveniently and separately maintained or replaced, and the maintenance cost can be reduced.
Description
Technical field
The utility model belongs to automobile technical field, is specifically related to be used for the oil inlet and oil return pipe assembly of load-carrying vehicle fuel tank.
Background technology
The oil inlet and oil return pipe assembly of existing load-carrying vehicle fuel tank is divided into two kinds of structures, and a kind of structure is an integral type for the oil inlet and oil return pipe assembly, and another kind of structure is that oil inlet and oil return pipe assembly and fuel tank casing are integral type.The defective that said structure exists is: if the oil inlet and oil return pipe assembly is an integral type with the fuel tank body, and then after the damage of oil inlet and oil return pipe assembly, can't single replacing oil inlet and oil return pipe, whole fuel tank is promptly scrapped, and economic loss is bigger.If the then whole fuel tank body of fuel tank of the different oil inlet and oil return bores of design also needs to make again, be unfavorable for the seriation management of product; If the oil inlet and oil return pipe assembly is that integral type is installed on fuel tank, then easily produce the leakage of oil problem between oil inlet and oil return pipe assembly and the fuel tank.
Summary of the invention
For the problem that the oil inlet and oil return pipe assembly structure that solves above-mentioned two kinds of fuel tanks exists, the utility model provides a kind of oil inlet and oil return pipe assembly that is used for the load-carrying vehicle fuel tank that is convenient for changing.
Concrete structural design scheme is as follows:
The oil inlet and oil return pipe assembly that is used for the load-carrying vehicle fuel tank, comprise the oil inlet and oil return pipe, the oil inlet end of oil inlet and oil return pipe is provided with filter screen, also comprise the oil pipe seat, the oil pipe seat is a column, is axially arranged with the tapped bore of perforation, and outside stage casing is provided with annular boss, its boss end is positioned at outside the fuel tank, and the Chinese lute joint by the threeway bolted connection; The other end of oil pipe seat is positioned at outside the fuel tank, and is connecting the other end of oil inlet and oil return pipe.
The utility model has solved in actual use, damages the problem of changing fuel tank assembly because of the oil inlet and oil return pipe assembly.Can regulate by the internal diameter of Chinese lute joint simultaneously and satisfy of the requirement of different driving engines, avoid situation, improve the commonality of fuel tank body member because of oil inlet and oil return pipe assembly internal diameter varies design specialized fuel tank for oil inlet and oil return pipe caliber.And connect with the Chinese lute joint form, oil pipe is more conducive to the reduction of oil circuit oil resistance towards can arbitrarily rotating; On the other hand, the structure design that the outer oil inlet and oil return joint of oil inlet and oil return pipe and fuel tank separates in the fuel tank makes things convenient for oil inlet and oil return mouth maintenance or replacing separately, has reduced maintenance cost.
