Abstract
The utility model relates to a water pump impeller for an automobile. The water pump impeller comprises a shaft sleeve, a blade and an impeller plate; the shaft sleeve is mounted on a shaft, and rotates along with the shaft; the impeller plate is vertical to the shaft sleeve; and the blade is an arc-shaped blade, and is located at the outer edge of the impeller plate and distributed around the sleeve. The water pump impeller is characterized in that the outer edge of the blade is thicker than the inner side of the blade, and the outer edge of the blade is uniformly transited to the inner side of the blade; an inclined surface is arranged at the part at the inner side of the blade; and corner transition is used between the blade and the impeller plate. According to the water pump impeller for the automobile provided by the utility model, no weak part which is pressed in a concentrated manner exists, so that the service life of the impeller can be prolonged.
Description
Technical field
The utility model relates to a kind of motor car engine component, relates in particular to a kind of auto pump impeller.
Background technique
Auto pump plays a part the cooling water cycle of starting inside to whole as the key components and parts of engine-cooling system.Can water pump vane be the effectively key of work of auto pump, to enough flow decisive role are provided.Current water pump vane is made up of axle sleeve and blade, and the root of blade is fixedly connected on the axle sleeve, along with axle sleeve rotates together.Its deficiency is, the root of blade is because stressed concentrating, and fracture easily makes the water pump can not supercharging.
The model utility content
The purpose of the utility model is to the problems referred to above that exist in the existing technology, and a kind of auto pump impeller of long service life is provided.
The utility model is achieved in that a kind of auto pump impeller, comprises axle sleeve, blade and wheel disc, and described axle sleeve is contained on the axle, rotates with axle; Described wheel disc is vertical with axle sleeve; Described blade is an arc shaped blade, is positioned at the outer rim of wheel disc and distributes around axle sleeve, and it is characterized in that: the outer edge thickness of described blade is greater than inboard thickness and even transition; At the blade inside line inclined-plane is arranged, adopt round-corner transition between blade and wheel disc.
The auto pump impeller of the utility model has increased the opening area of blade entrance point, because the variation of thickness and the guiding function on inclined-plane can make the auto pump impeller of the utility model that higher flow is provided under the same conditions.Because adopt fillet to connect, the utility model does not exist stressed concentrated weak part, the working life that can improve impeller.The utility model is simple in structure, can carry out rapid batch production through the injection moulding mode, reduces manufacture cost effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the plan view of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further to describe:
Like Fig. 1, shown in Figure 2, a kind of auto pump impeller comprises axle sleeve 1, blade 2 and wheel disc 3, and described axle sleeve 1 is contained on the axle, rotates with axle; Described wheel disc 3 is vertical with axle sleeve 1, and described blade 2 is an arc shaped blade, is positioned at the outer rim of wheel disc 3 and distributes around axle sleeve 1; Described blade 2 outer edge thickness have inclined-plane 4 greater than inboard thickness and even transition at blade 2 inside lines, and 3 on blade 2 and wheel disc adopt round-corner transition.
