Abstract
The utility model discloses a kind of buffering abrasion resistant type electromagnetic fuel pump being applied to automobile, comprise upper cover (1), shell (2), base (11), at this upper cover built with contact switch assembly (51), at this base built with valve member (52), at this shell built with coil (6), static iron core (29), dynamic iron core (27), mandrel (21), self lubrication bearing (5) is housed between described mandrel and static iron core, at the side of described static iron core, and at mandrel, move place between iron core and static iron core and cushion pad (28) is housed.Even if installing additional of the utility model self lubrication bearing makes the long-term wearing and tearing that pump in static iron core of mandrel also less, arranging of cushion pad has carried out effective buffering to the climbing power of dynamic iron core, strengthens the stability of work.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 buffering abrasion resistant type electromagnetic fuel pump that wearing and tearing when a kind of mandrel pumps in static iron core are less, have resiliency.
Object of the present invention realizes by following technical solution: buffering 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 coil, static iron core, dynamic iron core, mandrel and pressure spring, between described mandrel and static iron core, self lubrication bearing is housed, described static iron core side and mandrel, dynamic between iron core and static iron core place cushion pad is housed, this cushion pad is in the below of self lubrication bearing.
After adopting the present invention, even if installing additional of self lubrication bearing makes the long-term wearing and tearing that pump in static iron core of mandrel also less, arranging of cushion pad has carried out effective buffering to the climbing power of dynamic iron core, strengthens the stability of work.Thus extend 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 that the present invention cushions abrasion resistant type electromagnetic fuel pump.
Fig. 2 is the structural representation of the self lubrication bearing (having lubrication reinforced layer) in Fig. 1.
Embodiment
With reference to accompanying drawing 1, Fig. 2 is known, the present invention is applied to the buffering 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 (its external connection inserts 36), at this base 11 built with valve member 52, at this shell 2 built with coil 6, static iron core 29, dynamic iron core 27, mandrel 21 and pressure spring 9, between described mandrel 21 and static iron core 29, (center corresponding to coil 6) is equipped with self lubrication bearing 5 (upper), at the side of described static iron core 29, and at mandrel 21, move place between iron core 27 and static iron core 29 and cushion pad 28 is housed, this cushion pad 28 is in the below of self lubrication bearing 5.Arranging of cushion pad has carried out effective buffering to the climbing power of dynamic iron core, strengthens the stability of work.Have with mandrel 21 contacting point and lubricate reinforced layer 53 in described self lubrication bearing 5, particularly for mandrel, there is protection and wear and tear and lubrication.
Claims (1)
