Abstract
The utility model discloses an automotive water pump which comprises a pump body and an axial-connecting bearing, wherein the axial-connecting bearing penetrates in the inner cavity of the pump body; one end of the axial-connecting bearing is provided with a hub; the other end of the axial-connecting bearing is provided with an impeller; a plurality of circinate runners are evenly distributed on the circumstance of the impeller; a water seal and am impeller insert are arranged between the impeller and the axial-connecting bearing; and an elastic check ring is arranged between the hub and the axial-connecting bearing. Through adoption of the structure, the automotive engine drives the hub to rotate, and the hub drives the impeller to rotate by the axial-connecting bearing so as to realize the water pumping operation of the automotive water pump. The automotive water pump provided by the utility model has the advantages of simple structure, few used parts and low production cost. In addition, the impeller can be made of PPS-GF (polyphenylene sulfite-glass fiber)40 material, so that the overall weight of the impeller is lightened, the dynamic balance of the impeller and the product precision can be improved, the integral performance of the automotive water pump is improved, and the service life of the automotive water pump is prolonged.
Description
Technical field
The utility model relates to a kind of vehicle water pump.
Background technique
Auto pump is an important component in the motor car engine, but at present, existing vehicle water pump structure is complicated usually, and used component are more, thereby make cost of production higher.
Summary of the invention
To the deficiency of existing technology, the utility model provide a kind of light weight, easy to process, precision is high, good dynamic balance and the better vehicle water pump of rotproofness.
For realizing above-mentioned purpose; The utility model provides a kind of vehicle water pump, comprises the pump housing, shaft connecting bearing, and shaft connecting bearing is located on the pump housing inner chamber; Be equipped with wheel hub on one end of said shaft connecting bearing; Be equipped with impeller on the other end of shaft connecting bearing, be provided with water seal between impeller and the shaft connecting bearing, be provided with circlip between wheel hub and the shaft connecting bearing.
The utility model can further be set to be evenly distributed on the described impeller some whirlpool shape runners.
The utility model also can further be set to also be provided with between described impeller and the shaft connecting bearing impeller mold insert.
The beneficial effect of the utility model is: adopt said structure, motor car engine drives wheel hub and rotates, and wheel hub rotates through the shaft connecting bearing impeller; Thereby realize the pump water operation of vehicle water pump, so the vehicle water pump that the utility model provided, it is simple in structure; Used component are less, and cost of production is lower, and described in addition impeller can select for use the PPS-GF40 material to process; Make the overall weight of impeller alleviate, easy to process, also can improve the dynamic balancing and the product precision of impeller; Thereby make the overall performance of vehicle water pump be improved, and prolong its working life.
Description of drawings
Fig. 1 is the structure sectional view of the utility model;
Fig. 2 is the structural drawing of impeller in the utility model.
Embodiment
