Abstract
The utility model discloses an improved plunger pump mounting base structure. The improved plunger pump mounting base structure comprises a plunger pump mounting base, and a plunger pump mounting hole and a motor mounting hole formed on the mounting base. The improved plunger pump mounting base structure is characterized in that a leaking liquid storage cavity (13) for storing brake liquid of the plunger pump is formed on the motor mounting surface (11) of the plunger pump mounting base (10); and the leaking liquid storage cavity (13) is communicated with a motor mounting hole (12) through a groove (15). The leaking liquid storage cavity (13) is provided with an opening structure on the motor mounting surface (11). The improved plunger pump mounting base structure can effectively store the brake liquid leaking from the plunger pump in the leaking liquid storage cavity so as to prevent the leaking brake liquid from influencing the motor performance and the plunger pump.
Description
Technical field
The utility model relates to a kind of brake system of car field, and especially a kind of fitting seat body structure of the plunger pump that uses in anti-lock braking system in automobiles improves.
Background technique
At anti-lock braking system in automobiles is to use plunger pump to realize refluxing, finally reach among the ABS to control riding stability or drive anti-skidding function, prevent phenomenon such as sideslip that wheel lock up produces, whipping and drive the generation of skidding, guarantee control stability, shorten stopping distance.Be provided with plunger channel in the body that stops up pump that in antilock braking system (ABS), uses, in be provided with plunger cavity; Plunger cavity is provided with sealing cover in the port part that stops up passage, be with seal ring on the sealing cover, sealing cover adopts with body and is threaded, though employed seal ring quality requirement is very high, seal ring above when simultaneously plunger slides in plunger bushing can with plunger bushing in show continuous contact friction, causing the seal ring operating time to grow can wearing and tearing, the reduction sealing effect, even the plunger pump brake fluid occurs and leak, influence motor performance; And not having the brake fluid storage effect that the plunger pump brake fluid is leaked on the installation pedestal of plunger pump commonly used, the brake fluid that leaks directly has influence on motor performance or even has influence on the performance normality of ABS.
The model utility content
The utility model for solve existing plunger pump through work for a long time and influenced by working environment to produce down sealing wear to lose efficacy to reveal brake fluid situation and plunger pump its install pedestal do not have to the brake fluid that leaks draw that storage handles etc. present situation provide a kind ofly can reveal the fitting seat structural reform that brake fluid draws the plunger pump of depositing an independent place with losing efficacy and advanced structure because of the plunger pump seal ring.
The utility model is to solve the problems of the technologies described above the concrete technological scheme that is adopted to be: a kind of fitting seat structural reform of plunger pump is advanced structure, comprise the installation pedestal of plunger pump and be located at pedestal upper plug pump mounting hole, motor mounting hole are installed, the installation pedestal of described plunger pump is provided with the leakage liquid storage cylinder of plunger pump brake fluid on its motor attachment face, be communicated with by groove between described leakage liquid storage cylinder and the motor mounting hole.The leaking to draw to store up through groove of plunger pump brake fluid revealed in the liquid storage cylinder, can effectively the brake fluid that leaks from plunger pump be drawn to store up and reveal in the liquid storage cylinder, avoid revealing the influence of liquid to motor performance and plunger pump itself, solve original plunger pump fitting seat do not have a storage effect of drawing that plunger pump is leaked brake fluid.
As preferably, described leakage liquid storage cylinder on the motor attachment face for being provided with the cavity hatch structure.After upgrading seal ring, can pour out and clean by the leakage liquid that this hatch frame draws storage in liquid storage cylinder.
As preferably, the cavity bottom position of described leakage liquid storage cylinder is not higher than the motor bearings hole bottom level in the motor mounting hole.Can guarantee effectively that liquid storage cylinder can draw in the plunger pump brake fluid leakage scope of storage before system allows to upgrade Xinmi City's seal.
As preferably, it is low that the motor bearings in the recessed depth ratio motor mounting hole of described groove supports the anchor ring position, and its bottom portion of groove is not higher than the passage of plunger pump and motor mounting hole.
As preferably, described its cavity of leakage liquid storage cylinder is cylindrical body structure or other similar cavity body structure.
The beneficial effects of the utility model are: can effectively the brake fluid that leaks from plunger pump be drawn to store up and reveal in the liquid storage cylinder, avoid revealing liquid and cause harmful effect to motor performance and plunger pump itself.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation that the fitting seat structural reform of the utility model plunger pump is advanced structure.
Embodiment
Among the embodiment shown in Figure 1, a kind of fitting seat structural reform of plunger pump is advanced structure, comprise the installation pedestal of plunger pump and be located at pedestal upper plug pump mounting hole, motor mounting hole are installed, the installation pedestal 10 of described plunger pump is provided with the leakage liquid storage cylinder 13 of plunger pump brake fluid on its motor attachment face 11, be communicated with by groove 15 between described leakage liquid storage cylinder 13 and the motor mounting hole 12.Described leakage liquid storage cylinder 13 on motor attachment face 11 for being provided with the cavity hatch structure.The cavity bottom position of described leakage liquid storage cylinder 13 is not higher than the motor bearings hole bottom level in the motor mounting hole.It is low that motor bearings in the recessed depth ratio motor mounting hole 12 of described groove 15 supports anchor ring 14 positions, and its bottom portion of groove is not higher than the passage of plunger pump and motor mounting hole.Described leakage liquid storage cylinder 13 its cavitys are the cylindrical body structure.
