Description

Car Water Pump {WATER PUMP FOR VEHICLE}

An exemplary embodiment of the present invention relates to a water pump applied to a vehicle, and more particularly, to a vehicle water pump to which an electronic clutch is applied.

Currently, vehicle makers are trying to achieve two goals: improving fuel economy and reducing emissions in the process of developing a vehicle. Among them, the catalyst of the exhaust system is increased despite the significant increase in cost and weight to meet emission regulations. Increasing the load or increasing the capacity of the EGR cooler is applied.

In general, a method of forcibly circulating a coolant is applied to a vehicle. For this purpose, a coolant path is formed in a cylinder and a cylinder head of an engine, and a coolant path is forcibly supplied to a coolant path by a water pump to maintain a stable engine temperature. Let's do it.

The water pump for supplying the coolant is operated by the power transmitted through the belt to circulate the coolant to the "radiator → cylinder → cylinder head → radiator" to prevent the engine from overheating and deterioration.

The water pump rotates the central impeller with 6 blades by the power of the engine transmitted through the belt to pump the coolant to the cylinder.The rotation speed is set differently according to the ratio of the pulley, but it is approximately 1.2 on the crankshaft. Rotate at ~ 1.6 times speed.

Since the water pump is operated by the power transmitted through the belt at the same time as the engine starts, the water pump is always operated according to the operation of the engine regardless of the warm-up condition or the cooling condition of the engine to circulate the coolant.

Thus, while the engine is warmed up, fuel economy and exhaust gas can be stabilized. However, when the engine is started while the engine is sufficiently cooled, the warm-up time of the engine is delayed according to the circulation of the coolant, and thus cooling is performed. The friction resistance of the driven part is increased, causing a problem of increased wear.

In addition, the combustion efficiency is lowered due to the cooling of the engine, the fuel consumption is increased, the temperature rise of the exhaust gas is delayed, and the activation time of the catalyst is delayed. It implies

In addition, the fuel pump acts as a load on the crankshaft according to the regular operation of the fuel pump, thereby lowering the output efficiency of the engine, thereby causing a problem of lowering fuel efficiency.

This occurs because the water pump is not mechanically intermittent but only mechanically coupled in the process of interlocking with the crankshaft by the belt.

Exemplary embodiments of the present invention have been created to improve the above problems, by applying an electronic clutch, controlling the operation of the electronic clutch in accordance with the operating conditions of the engine and the temperature of the coolant, such as pumping of the coolant is optional. It provides a vehicle water pump to be made.

To this end, the water pump for a vehicle according to the exemplary embodiment of the present invention is a hub coupled to one end of the main shaft rotatably installed on the pump body, and an impeller coupled to the other end, and rotatable to the hub. And a clutch disc connected to the hub and selectively attached to the friction pad to be in close contact with the hub, wherein the friction pad is provided with a ring-shaped body part, and the mounting surface of the pulley is provided. On one side of the body portion corresponding to the plurality of protrusions are formed along the circumferential direction.

The vehicle water pump may include a ballistic unit exerting a force to the clutch disk between the clutch disk and the hub, and a field coil fixed to the pump body corresponding to the clutch disk.

In the vehicle water pump, coupling grooves to which the protrusions of the friction pad are coupled may be formed on the mounting surface of the pulley.

In the vehicle water pump, the protrusion may be in the form of a triangular rib.

In the vehicle water pump, the friction pad may be coupled to the pulley in an uneven form through the protrusion.

In the vehicle water pump, the friction pad may have a plurality of protrusions formed on the other side of the body portion corresponding to the clutch disk.

In the vehicle water pump, the friction pad may be coupled in the form of a spikey to the pulley.

In the vehicle water pump, the field coil may be magnetized by an external control signal to generate a magnetic force, and may control the connection between the clutch disk and the friction pad.

In the vehicle water pump, the clutch disk may be connected to the friction pad while the field coil is not magnetized to supply power of the pulley to the impeller to provide pumping of cooling water.

In the vehicle water pump, the clutch disk may be separated from the friction pad according to the magnetization of the field coil to idle the pulley.

According to the water pump for a vehicle according to the exemplary embodiment of the present invention as described above, by operating the clutch electronically in accordance with the operating conditions of the engine, the temperature of the coolant, the driver's will to transfer or block the power of the pulley to the impeller In this manner, pumping of the coolant through the impeller may be made selectively.

Therefore, in the present embodiment, it is possible to secure stable emissions without adding a loading amount of the catalyst for purifying exhaust gas, thereby providing cost reduction, and since the exhaust system components are not added separately, the weight of the vehicle is reduced to improve fuel economy. The effect is expected.

In addition, in the present embodiment, when the initial start is performed while the engine is cooled, the circulation of the coolant is blocked, so that the temperature of the engine oil can be quickly increased, thereby reducing oil friction and minimizing wear of each driving component, thereby improving durability. The effect is expected.

In this embodiment, the circulation of the coolant is actively controlled during the initial start-up of the engine, thereby improving fuel economy by reducing the activation time of the engine and stable combustion, and providing the emission stabilization by shortening the activation time of the catalyst. It is expected.

In addition, in the present embodiment, the contact area between the pulley and the friction pad can be increased by forming protrusions on the friction pad and coupling the protrusions to the engaging groove of the pulley.

Therefore, in this embodiment, the contact area between the pulley and the friction pad is increased, so that the friction heat between the clutch disk and the friction pad or heat generated in the field coil can be easily released through the pulley. In addition, in the present embodiment, the coupling rigidity of the friction pad and the pulley may be further increased through the protrusions.

Therefore, in this embodiment, since the heat generated from the friction coil or the heat coil generated by the friction force between the clutch disk and the friction pad can be actively dissipated through the pulley, the friction force between the friction pad and the clutch disk is not reduced. The slip can be prevented and the power transmission efficiency can be further improved.

In this embodiment, since the coupling strength between the pulley and the friction pad can be secured continuously, the relative movement between the clutch disk and the friction pad can be suppressed, thereby reducing the power transmission efficiency.

Therefore, the pulley 130 is rotated at a predetermined rate by the power transmitted from the crankshaft through the belt as the engine is started. As a result, the impeller 150 rotates to pump the coolant.

Therefore, the cooling water is pumped to the cooling channel formed in the cylinder (not shown) by the rotational force of the impeller 150 to maintain the engine temperature in a stable state.

In the present embodiment, the vehicle water pump 100 may apply an electronic clutch, and may control the operation of the electronic clutch according to the driving condition of the engine, the temperature condition of the coolant, and the driver's will to selectively pump the coolant. It is made of a structure.

The pump body 110 forms a coolant inlet for introducing coolant, and has a pulley 130 that is selectively connected to one end of the main shaft 270 to be described below and rotates thereon, and includes a main shaft ( It is connected to the other end of the other side 270 is provided with a rotating impeller 150 on the other side.

In the above, the pulley 130 is a power transmission through the belt from the crankshaft (not shown in the figure) of the engine, the through hole 131 is formed in the center, the through hole 131 in the pulley bearing 133 is installed.

Here, the clutch chamber 135 is formed on the rear surface of the pulley 130 along the circumference of the through hole 131, and the friction pad 210 described later may be mounted on the inner surface of the clutch chamber 135. have.

In the present embodiment, the friction pad 210 is made of a steel material, and is mounted on the inner surface of the clutch chamber 135 of the pulley 130, and the body portion 211 having a ring shape as shown in FIGS. 3 and 4. ), And a plurality of protrusions 215 are formed on one surface of the body portion 211 corresponding to the inner surface of the clutch chamber 135.

The protrusions 215 protrude along the circumferential direction on one side of the body portion 211 and are spaced apart from each other. In this case, the protrusion 215 may protrude in the form of a triangular rib.

Here, the friction pad 210 is bonded to the protrusions 215 of the body portion 211 to the inner surface of the clutch chamber 135.

That is, the friction pad 210 may be bonded to the protrusions 215 into the coupling groove 137 formed on the inner surface of the clutch chamber 135. At this time, the coupling groove 137 of the inner surface of the clutch chamber 135 has a shape corresponding to the protrusion 215.

The clutch disc 220 is disposed in the clutch chamber 135 of the pulley 130 so as to correspond to the other side of the friction pad 210, and the metal may be selectively in close contact with the other side of the friction pad 210. It is made in the form of a disc of material.

In this case, the clutch disk 220 is controlled whether the output of the power supplied to the pulley 130 in accordance with the engagement with the friction pad (210).

The hub 230 is rotatably coupled through the pulley bearing 133 mentioned in the through hole 131 of the pulley 130, and the clutch disk 220 through the bullet unit 240, which will be described later. Interconnected with

The bullet unit 240 is to connect the clutch disk 220 and the hub 230 and to exert a force to the clutch disk 220.

The shot unit 240 provides a spring force to the clutch disk 220 to connect the clutch disk 220 and the friction pad 210, the clutch disk 220 of the field coil 260 which will be described further below. It is made of a structure that can be compressed when moving toward the hub 230 by the magnetic force.

The shot unit 240 is formed as a rubber damper 241 of the rubber material capable of damping the movement of the clutch disk 220, the rubber damper 241 is the outer peripheral portion of the hub 230 and the clutch disk ( It is connected to the inner circumferential edge portion of the 220, and is mounted between the clutch disk 220 and the hub 230 through the pin-shaped support member 243.

The field coil 260 generates magnetic force by receiving power according to an external control signal, and is installed to correspond to the rear surface of the clutch disc 220 in the clutch chamber 135 of the pulley 130.

The field coil 260 is installed in a coil case 261 that can be magnetized by a magnetic force. The field coil 260 is surrounded by a cover 263 covered by the coil case 261 and disposed inside the coil case 261. .

The main shaft 270 is rotatably mounted to the pump body 110 through a pump bearing 271, one end is connected to the center of the hub 230, the other end sealing the pump body 110. The sealing unit 273 is connected to the impeller 150 has been mentioned in the state interposed.

Therefore, according to the water pump 100 for a vehicle according to the exemplary embodiment of the present invention configured as described above, the clutch disc 220 in the general state that the power is not applied to the field coil 260 first, as shown in FIG. Likewise, the rubber damper 241 is in close contact with the other side surface of the friction pad 210 by the elastic force.

Thus, when the power of the engine is provided to the pulley 130 through the belt, since the clutch disc 220 is connected to the hub 230 through the bullet unit 240 and in close contact with the friction pad 210, the pulley ( As the engine power is transmitted to the main shaft 270 through the clutch disc 220 and the hub 230 according to the rotation of the 130, the main shaft 270 rotates, so that the impeller 150 is the main shaft 270. It rotates and pumps the coolant.

The pumping of the coolant as described above is performed under the condition that the engine operates at high speed because the engine speed exceeds the set reference speed, or the engine speed is less than the reference speed or the temperature of the coolant is higher than the set temperature.

In addition, the pumping of the coolant is performed to provide rapid heating of the room when the heater switch is detected as operating on regardless of the engine speed and the temperature of the coolant.

However, when the condition does not satisfy the above conditions, for example, when the engine operates at a low speed or when the temperature of the coolant is less than the set temperature, or when the heater switch is detected as off, the field coil 260 according to an external control signal. ) Generates a magnetic force by receiving power.

Accordingly, the coil case 261 is magnetized by the magnetic force generated by the field coil 260. At this time, the coil case 261 pulls the clutch disc 220 as the magnetic force as shown in FIG.

Then, the clutch disk 220 overcomes the elastic force of the rubber damper 241 and is guided to the support member 243 to move toward the coil case 261 and is separated from the friction pad 210.

Therefore, as the clutch disk 220 is separated from the friction pad 210 as described above, the connection between the clutch disk 220 and the friction pad 210 is interrupted, so that the clutch disk 220 is transmitted to the main shaft 270 through the hub 230. As the power is cut off, the pulley 130 is idle, and the impeller 150 stops the pumping of the coolant while not rotating.

As described above, the vehicle water pump 100 according to the exemplary embodiment of the present invention operates the clutch electronically by an external control signal according to the operating condition of the engine and the temperature condition of the coolant, and so on of the pulley 130. Since power is transmitted to or blocked from the impeller 150, pumping of the coolant through the impeller 150 is selectively performed.

As a result, in this embodiment, a stable emission can be secured without adding a loading amount of a catalyst for purifying exhaust gas, thereby providing cost reduction, and since the exhaust system parts are not added separately, the weight of the vehicle is reduced to improve fuel economy. It becomes possible.

In addition, in the present embodiment, when the initial start is performed while the engine is cooled, the circulation of the coolant is interrupted, so that the temperature of the engine oil can be quickly increased, thereby reducing oil friction and minimizing wear of each driving part, thereby improving durability. .

In this embodiment, the circulation of the coolant is actively controlled at the initial start of the engine, thereby improving fuel economy by reducing the activation time of the engine and stable combustion, and providing the emission stabilization by shortening the activation time of the catalyst. do.

On the other hand, according to the vehicle water pump 100 according to an exemplary embodiment of the present invention, the condition that the power is not applied to the field coil 260, that is, the clutch disk 220 and the friction pad 210 is a rubber damper 241 When the impeller 150 rotates in a state of being closely contacted by the elastic force of) and pumps the cooling water, friction between the clutch disc 220 and the friction pad 210 is generated due to the rotational movement.

In other words, the power transmission between the clutch disk 220 and the friction pad 210 is most accurate when the relative motion between the clutch disk 220 and the friction pad 210 does not occur, and the clutch disk 220 and When relative motion occurs between the friction pads 210, slip conditions result in loss of power transmission.

That is, in order to prevent the relative motion between the clutch disc 220 and the friction pad 210 as described above, friction surface conditions, friction coefficients, contact areas, etc. of the clutch disc 220 and the friction pad 210 are important factors. Act as.

The friction conditions of the clutch disc 220 and the friction pad 210 are governed by the connection conditions therebetween, and the normal friction conditions necessarily generate heat, and most of the heat is lost due to the sliding at the initial contact. Heat is generated by the current applied to the field coil 260.

Here, the friction slip refers to the slip caused by the difference in relative motion before the clutch disc 220 is in close contact with the friction pad 210 and the slip that occurs immediately before the clutch disc 220 is separated from the friction pad 210. it means.

The generation of this heat lowers the friction surface characteristics, such as hardness, of the friction pad 210, thereby lowering the friction force between the clutch disk 220 and the friction pad 210.

In addition, the lowering of the frictional force causes a loss of power transmission in the path in which the rotational power of the engine is transmitted to the impeller 150, and acts as a factor of losing the function of power transmission.

Accordingly, in the exemplary embodiment of the present invention, the protrusions 215 are formed on the friction pad 210, and the protrusions 215 are coupled to the coupling groove 137 of the pulley 130 by the protrusions 215. The contact area between the friction pads 210 may be increased.

Therefore, in the present embodiment, the contact area between the pulley 130 and the friction pad 210 is increased, so that friction heat between the clutch disc 220 and the friction pad 210 or heat generated from the field coil 260 is pulled 130. It can be easily released through.

In addition, in the present embodiment, the coupling rigidity of the friction pad 210 and the pulley 130 may be further increased through the protrusions 215.

Thus, in this embodiment, since friction heat generated by the frictional force between the clutch disk 220 and the friction pad 210 or heat generated in the field coil 260 can be actively radiated through the pulley 130, friction The slip between the pad 210 and the clutch disk 220 can be prevented without dropping the friction force, and the power transmission efficiency can be further improved.

In this embodiment, since the coupling strength between the pulley 130 and the friction pad 210 can be secured continuously, the relative movement between the clutch disk 220 and the friction pad 210 can be suppressed, thereby driving power. It is possible to suppress a decrease in the transfer efficiency.

On the other hand, in the exemplary embodiment of the present invention, as shown in FIG. 6, as the first modification of the friction pad 210, the protrusions 215 are formed in the form of square ribs, and the friction pad 210 is the protrusion. The pulleys 130 may be coupled to the pulley 130 in an uneven form.

In addition, as shown in FIG. 7, the friction pad 210 may form a plurality of protrusions 217 on the other side of the body portion 211 corresponding to the clutch disc 220 as a second modification. .

In addition, as shown in FIG. 8, the friction pad 210 may be coupled to the pulley 130 in the form of a spiny as a third modification.

Modifications of the friction pad 210 as described above are intended to increase the contact area between the pulley 130 and the friction pad 210, and thus the effects thereof are described above, and thus, a detailed description thereof will be omitted.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications and changes can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. Naturally, it belongs to the scope of the invention.
