Abstract
The utility model discloses a novel electric fuel pump, which comprises a housing and an armature component, an end cover, a power line terminal and oil bearing. The power line terminal and the oil bearing are positioned on a brush bracket, and both the power line terminal and injection-molding inserts of the oil bearing are inserted in the end cover. The novel electric fuel pump has the benefits of improved consistency and stability of products, reduced operating staff and working hours, improved work efficiency and reduced cost. The positioning accuracy of a magnetic steel piece is higher, the stability of the magnetic steel piece is better and the assembly of the magnetic steel piece is simple. The operation of the armature component is stable and the efficiency is high. The novel electric fuel pump affectively prevents the problems of inoperation, high current, flameout at intervals and the like of an oil pump caused by jolt and shake under poor road conditions.
Description
Technical field
The utility model relates to a kind of motor car engine electric fuel punp.
Background technique
Power-line terminal on the end cap of existing electric fuel punp and oil-impregnated bearing all adopt manual pressing method to install, and wiring terminal leakage of oil situation is often arranged, consistency of product and less stable like this, and processing cost height.
The complete machine structure formula adopts axial commutator armature assembly to cause structure space limited, and do not adopt the axial end location, armature assembly only depends on the magnetic field of pump chamber magnet steel that it is held, armature jolts, just has when shaking unconfined upper and lower axial activity running into virtually, armature the pushing down the oil pumping blade and impact blade of intermittence when upper and lower play, the thing followed be exactly electric current high or do not work, intermittent situation such as flame-out.
The model utility content
At the deficiencies in the prior art, the utility model provides a kind of novel electric fuel punp.
To achieve these goals, technical solution adopted in the utility model is: the electric fuel pump, comprise shell and armature assembly, and end cap and power-line terminal and oil-impregnated bearing, power-line terminal and oil-impregnated bearing are positioned on the brush holder, and power-line terminal and oil-impregnated bearing injection moulding inserts are bumped in the end cap.
Be provided with the magnet steel location piece on the brush holder.
The bonnet of complete machine is provided with rivet, and rivet withstands on an end of armature assembly.
Armature assembly end-face structure form is placed in the complete machine.
The beneficial effects of the utility model: improve consistency of product and stability, reduced operator and man-hour, improved working efficiency and reduced cost.The magnetic steel plate Location accuracy is higher, and stability is better, and assembling is simple simultaneously.The armature assembly running is more steady, and efficient is higher.And jolting of preventing effectively that oil pump from producing under the bad situation of road conditions, shake the generation of bad phenomenon such as not working of causing, electric current height, intermittence be flame-out.
Description of drawings
Fig. 1, structural representation of the present utility model.
Embodiment
The electric fuel pump comprises shell 5 and armature assembly 3, and end cap 11 and power-line terminal 13 and oil-impregnated bearing 12, and power-line terminal 13 and oil-impregnated bearing 12 are positioned on the brush holder, and power-line terminal 13 and oil-impregnated bearing 12 injection moulding inserts are bumped in the end cap 11.Such structure had both guaranteed consistency of product and stability, had reduced personnel and man-hour simultaneously.Be provided with the magnet steel location piece on the brush holder, satisfy the requirement of magnet steel locating accuracy and stability, simultaneously, assembling is simple.The bonnet 4 of complete machine is provided with rivet 2, and the end that rivet 2 withstands on armature assembly 3 has position-limiting action, and the axial motion of armature assembly is controlled within the specific limits, make the armature assembly running more steady, and efficient is higher.Armature assembly 3 end-face structure forms are placed in the complete machine.Thereby complete machine structure is adjusted to end-face structure from armature assembly 3 axial arrangement makes the entire product structure that basic variation take place, preventing effectively that oil pump from producing under the bad situation of road conditions jolts, and vibrations cause does not work, electric current is high or the generation of intermittent bad phenomenon such as flame-out.
