Description
Technical Field
The utility model relates to a lower pump, in particular to a linkage lower pump.
Background
When the motorcycle or the electric vehicle brakes, the two-to-two linkage upper pump gives thrust through the upper pump pressure handle on the right side, and the piston in the lower pump on the right side is pushed to move upwards to drive the brake pad to realize braking; when the pump pressure handle on the left side gives thrust, the thrust is respectively given to the pistons in the lower pump on the left side and the lower pump on the right side through a three-fork piece, and the linkage braking of the front wheel and the rear wheel is realized, however, in such a linkage mode, too many pistons lead to the overlarge volume of the shell, and the air discharging nozzle on the outermost side of the shell is easy to hook or scratch things.
Disclosure of Invention
In view of the technical problems in the background art, the utility model aims to provide a linkage lower pump, and an exhaust port is arranged on the side surface of an installation part and used for installing an air discharge nozzle.
In order to solve the technical problems, the utility model adopts the following technical scheme: this kind of linkage pump down, including the casing, be equipped with the installation department on the casing, the installation department has preceding hole face and side, is equipped with a plurality of piston chamber in the casing, be equipped with the oil through hole on the piston chamber, the oil through hole intercommunication has the oil port that leads to, the oil port is located preceding hole face, wherein, the piston chamber intercommunication has the gas vent, the gas vent is located the side, the gas vent orientation with the oil port orientation is perpendicular.
Preferably, the number of the piston cavities is two, and the piston cavities are independent from each other.
The utility model has the beneficial effects that the exhaust port is arranged on the side surface of the installation part to install the air discharging nozzle, and compared with the original air discharging nozzle which is arranged on the oil pipe, the installation is convenient and the whole height of the shell is reduced. Thus, the present utility model is a substantial feature and improvement over the prior art.
Drawings
The details and working principles of the embodiments and examples of the present utility model are described below with reference to the drawings.
Fig. 1 is a schematic structural view of the present utility model.
In the figure: 1. a housing; 2. a mounting part; 3. a front aperture face; 5. a piston chamber; 7. an oil port; 8. and an exhaust port.
Description of the embodiments
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model; it is apparent that the described embodiments are only some, but not all, embodiments of the present utility model, and that all other embodiments obtained by persons of ordinary skill in the art without making inventive efforts are within the scope of this utility model.
Referring to the drawings, in the embodiment of the present embodiment, a linkage lower pump includes a housing 1, a mounting portion 2 is provided on the housing 1, the mounting portion 2 has a front hole surface 3 and a side surface, a plurality of piston cavities 5 are provided in the housing 1, oil holes are provided on the piston cavities 5, the oil holes are communicated with an oil through hole 7, the oil through hole 7 is located at the front hole surface 3, wherein, the piston cavities 5 are communicated with an air outlet 8, the air outlet 8 is located at the side surface, and the air outlet 8 faces and is perpendicular to the oil through hole 7.
The oil pipe is arranged on the oil port 7, the original air discharging nozzle is arranged on the oil pipe, the overall height of the shell 1 is determined by the air discharging nozzle, the air discharging nozzle is arranged on the side face of the installation part 2 at present, and the installation is convenient and fast, and the overall height of the shell 1 can be effectively reduced.
The following optimizations or further description can be made on the basis of the above embodiments, respectively.
Further, the number of the piston cavities 5 is two, and the piston cavities 5 are independent from each other.
The two piston cavities 5 meet the linkage requirement with the lowest standard, the volume of the shell 1 is minimum, and the influence of the shell 1 on the surrounding is reduced to the greatest extent.
The foregoing is a preferred embodiment of the present utility model, and it should be noted that the scope of the present utility model is not limited thereto. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the scope and spirit of the utility model as defined in the appended claims.
