Abstract
The utility model discloses a kind of mandrel abrasion resistant type electromagnetic fuel pump being applied to automobile, comprise upper cover (1), shell (2), base (11), at this upper cover (1) built with contact switch assembly (51), at this base (11) built with valve member (52), at this shell (2) built with mandrel (21), coil (6), dynamic iron core (27), static iron core (29), self lubrication bearing (5) is housed between described mandrel and static iron core.There is in described self lubrication bearing (5) lubrication reinforced layer (53).The setting of installing and lubricating reinforced layer additional of the utility model self lubrication bearing, even if make the long-term wearing and tearing that pump in static iron core of mandrel also less, thus extend the working life of mandrel, static iron core, enhance stability, improve usability and the quality of fuel pump.
Description
Technical field
The present invention relates to automobile component, specifically relate to a kind of fuel pump being applied to automobile.
Background technique
At present, be applied in the electromagnetic fuel pump on automobile, comprise upper cover, shell, base, at this upper cover built with contact switch assembly, at this base built with valve member, at this shell built with mandrel, coil, dynamic iron core, static iron core, due to the electromagnetic action of coil, iron core band moving mandrel is moved up and down in static iron core, thus contact switch assembly is in open or closed condition, makes valve member open oil-feed fuel feeding or close fuel cut-off.Because wearing and tearing when mandrel pumps for a long time in static iron core are comparatively large, have impact on the working life of mandrel or static iron core, also can affect the usability of this fuel pump.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide the mandrel abrasion resistant type electromagnetic fuel pump that when a kind of mandrel pumps in static iron core, wearing and tearing are less.
Object of the present invention realizes by following technical solution: mandrel abrasion resistant type electromagnetic fuel pump, comprise upper cover, shell, base, at this upper cover built with contact switch assembly, at this base built with valve member, at this shell built with mandrel, coil, dynamic iron core, static iron core, between described mandrel and static iron core, self lubrication bearing is housed.There is in described self lubrication bearing lubrication reinforced layer.
After adopting the present invention, the setting of installing and lubricating reinforced layer additional of self lubrication bearing, even if make the long-term wearing and tearing that pump in static iron core of mandrel also less, thus extends the working life of mandrel, static iron core, enhance stability, improve usability and the quality of fuel pump.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and mode of execution, the present invention is described in further detail.
Fig. 1 is the structural representation of mandrel abrasion resistant type electromagnetic fuel pump of the present invention.
Fig. 2 is the structural representation of the self lubrication bearing (having lubrication reinforced layer) in Fig. 1.
Embodiment
Reference accompanying drawing 1, Fig. 2 are known, the present invention is applied to the mandrel abrasion resistant type electromagnetic fuel pump of automobile, comprise upper cover 1, shell 2, base 11, at this upper cover 1 built with contact switch assembly 51 (and external connection inserts 36), at this base 11 built with valve member 52, at this shell 2 built with mandrel 21 (and pressure spring 9), coil 6, dynamic iron core 27, static iron core 29, between described mandrel 21 and static iron core 29 (center corresponding to coil 6) be equipped with self lubrication bearing 5 (upper, and under cushion pad 28).In described self lubrication bearing 5, (and with mandrel 21 contacting point) has and lubricates reinforced layer 53.Described static iron core 29 side and mandrel 21, dynamic between iron core 27 and static iron core 29 place cushion pad 28 (this cushion pad 28 is in the below of self lubrication bearing 5) is housed.The setting of cushion pad has also carried out effective buffering to the climbing power of dynamic iron core, strengthens the stability of work.
