Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bypass assembly for an automatic transmission oil temperature regulator,

The present invention relates to a temperature control device for an automatic transmission oil, and more particularly, to a temperature control device for an automatic transmission fluid, which is directly coupled to an oil warmer constituting a temperature control device, To a bypass assembly for a temperature control device of an automatic transmission oil according to a new type in which a pass operation can be performed.

Generally, an automatic transmission of a vehicle capable of automatic shifting is a device that automatically operates the clutch and the transmission in accordance with the speed of the vehicle.

In such an automatic transmission, automatic transmission fluid (ATF) serving as a working oil and lubricating oil for smoothly transmitting the power of the engine to the drive shaft is used.

When the temperature of the automatic transmission oil is low, the viscosity of the automatic transmission oil is inevitably increased. Therefore, when the automatic transmission oil is directly flowed into the oil circulation cylinder, the flow of the automatic transmission oil can not be smoothly performed.

Accordingly, conventionally, a temperature control device for an automatic transmission oil including an oil heater is separately provided, so that the automatic transmission oil can always maintain an appropriate temperature. In regard to such oil warmers, Japanese Patent Application Laid- 0013421 and domestic patent application No. 10-2012-0059316.

However, since the conventional oil warmer according to the related art is configured to circulate the automatic transmission oil regardless of the temperature of the cooling water, when the cooling water temperature is low, And a problem that the automatic transmission oil is further lowered due to the temperature of the cooling water may be caused.

Conventionally, a separate bypass valve is additionally provided on a conduit through which the automatic transmission oil is transferred from the automatic transmission to the oil warmer. When the temperature of the cooling water is low, the oil of the automatic transmission is passed through the oil warmer And can be bypassed to an automatic transmission or an apparatus for increasing the temperature of other oil. The related art is as described in Korean Patent Laid-Open Nos. 10-2012-0050547 and 10-0353917.

Particularly, in recent years, a technology has been provided in which the structure for bypassing the coolant is integrated with the oil warmer, and this is as described in Japanese Patent No. 10-1283591.

However, in the above-described prior art, the connection pipe for bypassing the coolant is formed to have a larger diameter than the discharge port for discharging the coolant, and the entire portion of the discharge hole through which the coolant is discharged from the oil warmer, And the coolant bypassed along the connection pipe is not discharged to the discharge port because the communicating portion is a closed portion that is the endmost end of the connection pipe, The problem of flowing into the oil warmer has arisen, and the conventional technology described above has not been applied as an actual product.

Although the discharge port is formed to have a size larger than that of the connection pipe in order to prevent a problem according to the related art described above, the discharge port is connected so as to face the direction perpendicular to the connection pipe, The amount of the runt introduced into the oil warmer through the discharge hole is inevitably greater than the runout is discharged to the discharge port.

 In addition, since the above-described conventional technique employs a deformable member of a coil spring structure in which the valve unit is made of a shape memory alloy, there is a disadvantage that operation reliability is low and manufacturing cost is expensive, There is a problem that it is difficult to manufacture due to the necessity of fixing by welding in the cap.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems of the prior art. The object of the present invention is to provide an oil warmer which can be combined with the oil warmer constituting the temperature adjusting device, The present invention provides a bypass assembly for a temperature control apparatus for an automatic transmission oil according to a new type that enables simple and accurate bypass operation and prevents the bypassed coolant from being reintroduced into the oil warmer.

The connection pipe portion may include a first connection pipe having one end formed integrally with the inlet side communication portion and the other end formed to face the side where the outlet side communication portion is located, And one end of the first connection pipe is connected to the coolant return pipe, and the other end of the second connection pipe is connected to the coolant return pipe, And a branch tube branched from the branch tube.

In addition, the branch pipe is formed integrally with the first connection pipe and is branched so that one end of the second connection pipe and the other end of the first connection pipe are detachably coupled to each other.

Further, the second connection pipe is formed to pass through a part of the outflow-side communicating portion.

In addition, the operation valve portion may be located at a branch portion in the connection conduit portion and may be installed to be movable along the inside of the connection conduit portion, while a coolant provided from the engine through the coolant inlet pipe is connected to the inlet- A support pin fixed to the inside of the connection pipe portion at one end and positioned in the closing membrane at the other end, An expansion member formed of a material to be expanded and fixed in the inside of the closure membrane and having an insertion groove into which the support pin is inserted is formed inside the expansion membrane; And a restoring member for providing a movement force to close the side on which the outflow-side communicating portion is located It shall be.

As described above, the bypass assembly for the temperature control device of the automatic transmission oil according to the present invention can reduce the manufacturing cost by allowing the shape of each part of the automatic transmission oil to be optimized in consideration of the injection molding operation I have.

In particular, since the second connection pipe is formed to be directly connected to the outer pipe through the part of the outflow-side communication part, the communication part between the outflow-side communication part and the second connection pipe is perpendicular to the axial direction of the second connection pipe It is possible to minimize the inflow of coolant, which is bypassed along the second connection pipe, into the oil warmer through the outflow-side communication portion.

Here, the oil warmer 100 is a portion through which a coolant provided from an engine passes, and is a portion through which the automatic transmission oil (ATF) provided from the automatic transmission is passed. By using the coolant heat, 1, 2, 6, and 9, the oil warmer 100 is provided with four oil chambers 100a, 100b, An oil outlet 110, an oil outlet 120, a coolant inlet 130, and a coolant outlet 140 are respectively provided in the oil passage 110. [

The oil inlet 110 and the oil outlet 120 are provided at two corners which are diagonally opposite to each other at four corners of the upper surface of the oil warmer 100. The coolant inlet 130 and the coolant outlet 140 Are provided at the other two corners of the upper surface of the oil warmer 100 that are diagonally opposite to each other.

The bypass assembly 200 according to an embodiment of the present invention includes the inlet side communication portion 210, the outlet side communication portion 220, the connecting conduit portions 230, 240 and 250, and the operation valve portion 260 And will be described in more detail for each configuration.

First, the inlet-side communication portion 210 is a portion coupled to the coolant inlet 130 of the oil warmer 100.

In the embodiment of the present invention, it is shown that the inlet side communication part 210 is formed as a tubular body extending upward while covering the coolant inlet port 130.

At this time, the upper surface of the inflow communicating part 210 is closed, and on both circumferential surfaces of the inflow communicating part 210, coupling flanges 211, which are bolted to the upper surface of the oil warmer 100, Respectively.

Next, the outflow-side communicating portion 220 is a portion coupled to the coolant outlet 140 of the oil warmer 100.

In the embodiment of the present invention, it is shown that the outflow-side communicating part 220 is formed as a tubular body extending upward while covering the coolant outlet 140.

At this time, an upper surface of the outflow-side communicating part 220 is closed, and a coupling flange 221, which is bolted to the upper surface of the oil warmer 100, is formed on a circumferential surface of the outflow- Respectively.

Next, the connection pipe portion receives the coolant from the engine and transfers the coolant to the inlet side communication portion 210, or directly transmits the coolant to the coolant recovery pipe 310 that recovers the coolant by the engine It is a conduit to be connected.

The connection pipe portion includes a first connection pipe 230 formed integrally with the inlet communication portion 210, a second connection pipe 240 connected to the coolant return pipe 310, And a branch pipe 250 branched from any one of the connecting pipes.

One end of the first connection pipe 230 is integrally formed on the circumferential surface of the inflow side communicating part 210 and the other end of the inflow side communication part 230 is connected to the inflow side communication part 210. [ And the other end of the first connection pipe 230 is disposed to face the side where the outflow-side communication portion 220 is located.

The second connection pipe 240 is formed in a tubular shape having a bent part. One end of the second connection pipe 240 is connected to the other end of the first connection pipe 230 And the other end of the second connection pipe 240 is connected to the coolant recovery pipe 310 while extending outwardly through a portion where the outflow side communication part 220 is located.

One end of the branch pipe 250 is formed to be branched from the first connection pipe 230 and the other end of the branch pipe 250 is extended outward so that the coolant inlet pipe 320 is connected . At this time, the branch pipe 250 is formed to be perpendicular or inclined to the axial direction of the first connection pipe 230 in consideration of the connection direction of the coolant inlet pipe 320. Although not shown, the branch pipe 250 may be branched from the second connection pipe 240.

3, the first connection pipe 230 and the second connection pipe 240 may be separately manufactured. Then, the first connection pipe 230 and the second connection pipe 240 may be connected to each other, And the other ends of the tube 230 are connected to each other to form a single body.

Considering that a plurality of pipelines formed by the connection pipes 230 and 240, the branch pipes 250 and the respective communication pipes 210 and 220 are directed in different directions, when the connection pipe portion is manufactured as a single body, Not only is the size very large, but also the incidence of defects becomes extremely high, so that the overall manufacturing cost will increase.

Accordingly, it is most advantageous to separately manufacture the first connection pipe 230 and the second connection pipe 240, and then connect them together, thereby reducing manufacturing cost.

Furthermore, in the embodiment of the present invention, the second connection pipe 240 is formed to pass through a part of the peripheral side of the outflow-side communicating part 220.

In other words, if the second connection pipe 240 and the outlet communication part 220 are connected to each other by a separate pipe, the structure of the injection molding machine for forming the separate pipe is very complicated The number of the cores for injection molding increases, and the size of the injection molding machine increases. However, as in the embodiment of the present invention described above, the outflow-side communicating portion 220 is directly connected to the second connecting pipe 240 The piping is connected to each other so that the structure of the injection molding machine can be simplified and the total size of the injection molding machine can be reduced by reducing the number of cores for injection molding.

Particularly, the second connection pipe 240 is configured to pass only a part of the periphery of the outflow-side communication part 220, and the communication part between the outflow-side communication part 220 and the second connection pipe 240 may be formed The coolant that is bypassed along the second connection pipe 240 is directed to a direction perpendicular to the axial direction of the second connection pipe 240 and flows into the oil warmer 100 through the outflow communication part 220 It only takes place very little.

In addition, a portion of the first connection pipe 230 to which the branch pipe 250 is branched while being joined to the second connection pipe 240 is formed to have an expanded structure compared to other portions, And a portion of the second connection pipe 240 is configured to be inserted into the expanded portion of the first connection pipe 230.

Next, the operation valve unit 260 continues to operate until the temperature of the coolant supplied from the coolant inlet pipe 320 through the branch pipe 250 reaches a sufficient temperature for raising the temperature of the automatic transmission oil. The coolant is directly bypassed through the second connection pipe 240 to be recovered to the coolant recovery pipe 310. If the temperature of the coolant is sufficient to raise the temperature of the automatic transmission oil, Is guided to pass through the inside of the oil warmer 100 through the first connection pipe 230 and the inlet communication pipe 210 and is provided at a branching portion between the connection pipes 230 and 240 and the branch pipe 250 .

The detailed configuration of the operation valve unit 260 may be various. In the embodiment of the present invention, the operation valve unit 260 is a valve having a structure that is automatically operated according to the coolant temperature.

3 and 8 and 11, the operation valve 260 of the bypass assembly according to the embodiment of the present invention includes a closing membrane 261, a support pin 262, An expanding member 263, and a restoring member 264. [0100]

The closing membrane 261 is disposed at a branching portion between the connection pipes 230 and 240 and the branch pipe 250 so as to be movable along the inside of the first connection pipe 230.

At this time, the tip of the closing membrane 261 is formed to have an outer diameter enough to partly penetrate into the interior of the second connection tube 240 located in the expanded portion of the first connection tube 230, The rear end of the first connection pipe 261 is formed to have an outer diameter enough to close the boundary between the expanded portion and the non-expanded portion of the first connection pipe 230. The closure membrane 261 is connected to the coolant return pipe 310 through the coolant inlet pipe 320 so that the coolant supplied from the engine is connected to the inlet side communication pipe 210, It is possible to selectively block the transmission of the signal to the site where the signal is transmitted.

The supporting pin 262 is a portion for guiding while supporting the movement of the closing membrane 261.

One end of the support pin 262 is fixed to the inside of the first connection pipe 230 and the other end of the support pin 262 is positioned in the closing membrane 261.

The expansion member 263 is made of a material that expands when the temperature is higher than a predetermined temperature and is filled in the inside of the closing membrane 261. Inside the expansion membrane 263, 263a are formed.

Particularly, the above-described expansion member 263 is formed of wax that expands when providing heat above the set temperature. Wherein the wax is a water-insoluble monovalent or divalent alcohol fatty acid ester. That is, when the temperature of the coolant becomes equal to or higher than the preset temperature, the expansion member 263 is expanded and the space in the insertion groove 263a is reduced, whereby the support pin 262 is inserted into the insertion groove 263a so that the closing membrane 263 can be moved.

When the expansion member 263 is not inflated and deformed, the closing member 261 is moved to the side where the outflow-side communicating portion 220 in the first connection pipe 230 is located, And a coil spring for enclosing the closing membrane 261 as an example of providing a moving force to close the side channel. At this time, one end of the restoring member 264 is fixed to the coupling portion between the connection pipes 230 and 240, and the other end of the restoring member 264 is fixed to the rear end side of the closing membrane 261.

In the following, the operation of the bypass assembly 100 according to the embodiment of the present invention described above will be described in more detail.

First, in the initial state in which the engine is not operated, the coolant is not supplied from the engine and the automatic transmission oil is not supplied from the automatic transmission, and as shown in FIGS. 6 to 8 The closing membrane 261 constituting the operation valve unit 260 is maintained in a state in which the coolant inlet side of the first connection pipe 230 is closed by the restoring force of the restoring member 264. [

When the engine is started in the initial state described above, coolant is supplied from the engine and the automatic transmission oil is supplied from the automatic transmission.

At this time, the coolant supplied from the engine flows into the branch pipe 250 through the coolant inflow pipe 320, passes through the branch portion with the first connection pipe 230, passes through the second connection pipe 240, And then discharged through a coolant recovery pipe 310 connected to the second connection pipe 240. [

The automatic transmission fluid supplied from the automatic transmission flows into the oil warmer 100 through the oil inlet 110 formed in the oil heater 100 and flows through the oil outlet 100 formed in the oil warmer 100 120 to the automatic transmission again.

Accordingly, since the automatic transmission oil is not heat-exchanged from the coolant, the temperature of the automatic transmission oil may be lowered due to the low temperature of the coolant.

When the temperature of the coolant is higher than the predetermined temperature (for example, 70 DEG C) during the above-described process, the expansion member 263 of the operation valve unit 260 located in the coolant- It gradually expands.

When the expansion member 263 is inflated, the outer surface of the expansion member 263 is press-fitted into the closing membrane 261, so that the inflation member 263 can not be expanded to the outside, The support pin 262 located in the insertion groove 263a is gradually pushed out of the insertion groove 263a due to the reduction in the internal space of the insertion groove 263a, .

However, considering that the support pin 262 is fixed in the first connection pipe 230, the expanding member 263 is substantially supported by the support pin 262 And the closure membrane 261 surrounding the expansion member 263 is gradually moved toward the second connection pipe 240 together with the expansion member 263 so that the branch membrane 261 250) and the second connection pipe (240).

Accordingly, since the communication between the branch pipe 250 and the first connection pipe 230 is made open, the coolant introduced into the branch pipe 250 flows through the first connection pipe 230 And flows into the oil warmer 100 through the coolant inlet 130 of the oil warmer 100 after flowing into the side communicating part 210. This is as shown in FIGS. 9 to 11 attached hereto.

The coolant flowing in the oil warmer 100 is heat-exchanged with the automatic transmission oil flowing in the oil warmer 100 while being partitioned from the coolant, and by the heat exchange with the coolant, The temperature can be gradually increased to achieve an appropriate temperature.

As a result, the bypass assembly 200 according to the embodiment of the present invention can achieve a reduction in the manufacturing cost by allowing the shape of each part of the bypass assembly 200 to achieve an optimal shape considering the injection molding operation. That is, since the connection structure between each of the connection pipes 230 and 240 and the respective communication parts 210 and 220 is designed in consideration of the core position of the injection molding machine, the number of cores, the entering direction of the core, and the like, the size and manufacturing cost of the injection molding machine are remarkably reduced It is possible.

Particularly, the second connection pipe 240 is formed so as to be directly connected to the outer pipe through the part of the outflow-side communication part 220, and also to be connected to the second connection pipe 240 through the communication between the outflow-side communication part 220 and the second connection pipe 240 The coolant is bypassed along the second connection pipe 240 in a direction perpendicular to the axial direction of the second connection pipe 240. The coolant bypasses the second connection pipe 240 through the outflow communication part 220, (100) can be minimized.

In addition, the bypass assembly according to the embodiment of the present invention is configured such that the expansion member 263 for operation of the operation valve unit 260 is formed of wax, and the moving force due to the expansion deformation of the wax, Since the closing membrane 261 can be forcibly moved by the restoring force of the sealing member 264, the operation reliability can be improved remarkably.
