Fuel pump support assembly for vehicle

Abstract

The invention discloses a fuel pump support assembly for a vehicle. The fuel pump support assembly comprises a disc-shaped support body, a fuel refined filtration filter, an adjuster assembly, a far-end injection connector and a pump core, wherein a large mounting hole and a small mounting hole which are provided with axes extending up and down and communicate with each other are formed in the position, corresponding to the fuel refined filtration filter, of the center of the support body, a heating pipe clamping sleeve penetrating through the support body up and down is arranged on the support body, a far-end injection device clamping sleeve with the axis extending up and down is further arranged on the support body, a U-shaped oil level indicator receding notch which is concave inwards and provided with an opening in the side surface is formed in the side surface of the support body, and oil pipe clamping heads are further distributed on the side surface of the support body. The integration is high, the cost is low and mounting is convenient; the shell pump core is arranged outside and is not wrapped by a filter core, so that the heat dissipation is good; when upper and lower covers of the filter are welded, the welding area is reduced, the production difficulty is reduced, and the production stability is improved; the weight of the filter with the same filtering efficiency is greatly reduced, and the injection molding cost is reduced; and the size is small and the filtering efficiency is high.

Description

technical field [0001] The invention relates to a vehicle fuel pump support assembly, which belongs to the technical field of electric fuel pumps. Background technique [0002] The National VI emission regulations have been officially released. Major OEMs have launched National VI models one after another. Parts are very demanding. As early as before the National V, most of the fuel fine filter filters of the models were arranged outside the fuel tank. The number of roads and interfaces is reduced to reduce the fuel evaporative emission value, and at the same time, the convenience of replacing the fuel fine filter is considered. [0003] The existing electric fuel pump support such as figure 1 As shown, it is only used to install the electric fuel pump and pressure regulator, and does not integrate the remote injection structure, the snap-in heating pipe structure, the snap-in oil pipe structure, and the snap-in filter structure. [0004] Existing fuel filters such as ...

AI Technical Summary

Problems solved by technology

The fuel fine filter is too bulky, the small interface assembly is difficult to install, a lot of plastic materials are used, the cost is high, and the shell volume is large, the injection deformation is large, the production is difficult, and the stability after welding with the upper and lower end caps is poor

[0005] And the existing filter element is cylindrical, with a large diameter and a small height. It includes a filter element base and a filter element top ring. It is a cylindrical shape surrounded by filter paper after several equal parts and folded in half. The center of the top ring is the oil outlet of the filter element. The width of each equal part of the filter is 12mm, the height of the filter is 39mm, and the diameter is about 80mm, resulting in The entire fuel pump filter is bulky

Both the base of the filter element and the top ring of the filter element are sealed and installed with the housing through an O-ring, which is bulky and expensive
