Automotive Water Pump Blade Variable Device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle water pump blade variable device, and more particularly, to a vehicle water pump blade variable device in which the performance of a heater is improved when the engine is started in winter according to the increase of the variable blade pitch and wax capsule of the water pump when the vehicle is started. .

In general, the cylinder block used in automobiles is used as the foundation structure of the engine.

The cylinder block of such an automobile engine is usually integrally cast, where various structures are installed, and a part for installing a valve mechanism is provided, a cylinder head is installed on the upper surface of the cylinder block, and a bearing is disposed between the lower center part. Crankshaft is to be installed.

As described above, the structure of the cooling device installed in the cylinder is briefly described. The water pump is driven by the crankshaft through the belt to circulate the coolant, the engine is cooled by the coolant circulated by the water pump, and the heat in the engine. It consists of a radiator for cooling the cooling water absorbed by the, and a hose connecting it so that the cooling water can pass through the radiator engine and the water pump.

In the conventional cooling device configured as described above, when the water pump is driven by the crankshaft through the belt and forcedly circulates the coolant, the superheated engine is cooled by the forcedly circulated coolant, and the coolant that cools the overheated engine is radiated along the hose. The radiator cools the cooling water and circulates it again through the hose to the water pump. When the cooling water for cooling the combustion chamber is burned in the cylinder during the combustion period, the temperature reaches about 2,000 to 2,500 ° C. Conductive to the cylinder wall, cylinder head, piston valve and other parts.

Referring to the configuration of a conventional water pump configured as described above as shown in FIG. 1, the water pump 1 has a pulley 5 formed at one side of the bearing shaft 3 and the water pump 1 at the other side. The blade 7 for cooling) is formed, and the pulley 5 is formed with a belt 9 for transmitting a driving force to the water pump 1.

The blade for cooling the conventional water pump is a pulley is rotated when the belt is driven in a state fixed to one side of the bearing shaft, and the water pump is cooled based on this rotational force.

However, since the conventional blade having such a device is a fixed type, the cooling performance capacity is limited, which means that if the heater performance is good, the cooling performance is poor. On the contrary, if the cooling performance is good, the result is a decrease in the performance of the heater. If the performance of the heater is insufficient at start-up 10 to 20 minutes after starting the problem that can be expected more wind.

Therefore, the present invention has been made to solve the fundamental problems of the prior art, the purpose is to reduce the cooling performance at the start of the vehicle to increase the performance of the heater, increase the cooling performance when the engine temperature is increased, the heater performance is reduced To provide a vehicle water pump blade variable so that it can be.

In order to achieve the above object, the present invention is a spring inserted into the outer peripheral surface of the auxiliary shaft formed on one side of the bearing shaft, a wax capsule having a small pitch by the tension of the spring at startup, and the wax capsule is expanded The water pump blade variable device for a vehicle characterized in that it is composed of a rotating body to overcome the tension of the spring and move to one side when the pitch has a high pitch, the blade is variable according to the movement of the rotating body to adjust the heater performance and cooling performance To provide.

In the present invention as described above by changing the blade fixed to the water pump to start in the winter, the hot wind can be projected to improve the quality of the product.

(Actual example)

Hereinafter, preferred embodiments of the present invention as described above will be described in more detail with reference to the accompanying drawings.

2 is a configuration diagram showing the operating state of the blade according to the present invention, (A) is a state in which the capacity of the blade is reduced, (B) is a state in which the capacity of the blade is increased.

First, as shown in FIG. 2, a spring 15a is inserted into an outer circumferential surface of an auxiliary shaft 15 formed on one side of a bearing shaft 13, and the tension of the spring 15a is started when the spring 15a is inserted. By the wax capsule 17 is always provided with a small pitch, and when the wax capsule 17 is expanded to have a high pitch, the rotating body 19 to overcome the tension of the spring (15a) and move to one side is the wax The blade 11 is formed in the middle of the capsule 17 and the auxiliary shaft 15, and the blade 11 is formed on the outer circumferential surface of the rotating body 19 so as to be variable according to the movement of the rotating body 19 so as to adjust the heater performance and the cooling performance. Configure to be combined.

Here, the blade 11 of the water pump 10 has a smaller pitch of the wax capsule 17, the capacity decreases, cooling performance is reduced, and the performance of the heater is increased, on the contrary, if the pitch is high, the cooling capacity is increased. To increase and decrease the performance of the heater, the purpose of the blade 11 is a rotating disk 11a is formed at the bottom, the rotating disk (11a) the rotating shaft (11b) is formed integrally with the rotating shaft 11b is eccentrically comprised by the rotating disk 11a.

The operational effects of the present invention configured as described above are as follows.

Before starting first, the wax capsule 17 is contracted by the tension of the spring 15a formed on the outer circumferential surface of the auxiliary shaft 15 as shown in FIG. When starting in such a state, since the wax capsule 17 is contracted by the tension of the spring 15a and the pitch is small, the capacity of the blade 11 is reduced, cooling performance is reduced, and conversely, the performance of the heater is increased. You can expect hot wind directly from the heater.

In the above state, when the engine temperature increases, the wax capsule 17 is expanded as shown in FIG. 2 (B), and by this expansion, the rotor 19 moves to the right while overcoming the spring force of the spring 15a. Done. In this case, since the rotating shaft 11b of the rotating disc 11a is eccentric in the rotating body 19, the blade 11 is variable as shown in the direction of the arrow, thereby increasing its cooling capacity and increasing the performance of the heater. In addition, the cooling performance of the water pump 10 is improved. At this time, the pitch of the wax capsule 17 is high.

The present invention as described above is able to improve the quality of the product because the blade is variable according to the use by removing the blade fixed to the conventional water pump.

In addition, the variable blade is a very useful invention that the effect of reducing the cooling capacity as the capacity is reduced when the pitch of the wax capsule is reduced, the heater is increased, the hot wind is discharged immediately when starting in winter.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and is not limited to the spirit of the present invention. Various changes and modifications can be made by those who have
