Abstract
The utility model relates to a vehicular vacuum pump, which is not easy to be damaged and beneficial to prolonging the operating life, saving the material cost and the repairing cost. The structure of the utility model comprises a vacuum pump rotor arranged inside the pump body, characterized in that a cooperated connection section of the vacuum pump rotor and a power rotation shaft of the vacuum pump rotor is a regular polygon, wherein employing the square is the best scheme. Since changing the connection transmission mode of the vacuum pump rotor and the power rotation shaft from the original inner gear ring and outer gear ring cooperating transmission to the regular polygon frame and shaft cooperating transmission, especially the square frame, the utility model has a more homogeneous force and can largely reduce the abrasion, thereby prolonging the operating life, saving the material cost and the repairing cost. In addition, employing the cooperating connection structure of regular polygon especially the square, the utility model is more convenient in the process manufacture, compared with the original gear ring cooperating connection structure.
Description
Technical field
The utility model relates to a kind of vehicle vacuum pump.
Background technique
Be used at present the vacuum pump that skidding uses on the car, its vacuum pump rotor is a gear matched with the section that is connected of power shaft, be that vacuum pump rotor and its power shaft are to rely on the transmission that is connected of ring gear and external toothing, because the distance of the tooth top of each tooth of transferring power at the bottom of the tooth is very short, the ring gear of using process intermediate pump rotor and the external toothing of power shaft all are worn easily, finally cause transmission failure and must change vacuum pump rotor even power shaft, cause cost of material and repair cost to increase greatly, the repairing time prolongs greatly.
The model utility content
The purpose of this utility model provides a kind of vehicle vacuum pump, and it is not easy to damage, and helps increasing the service life economical with materials cost and repair cost.
The technical solution of the utility model is to constitute like this, and it comprises the vacuum pump rotor of being located in the pump housing, and it is characterized in that: the section that is connected of vacuum pump rotor and its power shaft is a regular polygon.
In order to reach preferable transmission efficiency and less wear rate, best-of-breed technology scheme of the present utility model is: the section that is connected of vacuum pump rotor and its power shaft is square.
Than prior art, the utility model is owing to cooperates transmission to change regular polygon (especially square) frame and a cooperation transmission into by in the past ring gear the kind of drive that is connected of vacuum pump rotor and its power shaft with external toothing, therefore stressed more even, can significantly reduce wearing and tearing, thereby increase the service life economical with materials cost and repair cost.In addition, adopt the especially foursquare structure that is connected of regular polygon, compared with original gear ring structure that is connected, also convenient in manufacturing.
Description of drawings
Fig. 1 is that the utility model rotor of vehicle vacuum pump rotates schematic representation with being connected of power shaft.
Fig. 2 is that the utility model rotor of vehicle vacuum pump is connected the rotation schematic representation with the another kind of power shaft.
Embodiment
The utility model specific embodiment comprises the vacuum pump rotor of being located in the pump housing 1, it is characterized in that: vacuum pump rotor 1 is a regular polygon with the section that is connected of its power shaft 2, wherein adopting square as shown in Figure 1 is optimum scheme, also can adopt regular pentagon or regular hexagon shapes such as (as shown in Figure 2).
Claims (2)
1. vehicle vacuum pump, it comprises the vacuum pump rotor of being located in the pump housing (1), it is characterized in that: vacuum pump rotor (1) is a regular polygon with the section that is connected of its power shaft (2).
2. vehicle vacuum pump according to claim 1 is characterized in that: vacuum pump rotor (1) is square with the section that is connected of its power shaft (2).
