Description
- This application is based on Japanese Patent Application No. 2008-1103 filed on Jan. 8, 2008, the disclosure of which is incorporated herein by reference.
- The present invention relates to a blower unit for a vehicle for generating cooling air for cooling a heat exchanger, such as a radiator, of a vehicle.
- In a conventional blower unit employed for a heat exchanger having a relatively long core, two axial fans are disposed on a downstream side of the core with respect to a flow of air, and each of the fans is provided with a fan motor. That is, the blower unit has the fan motors with the same number as the number of the fans. In such a case, the entire size and the weight of the blower unit increases. Also, the number of parts increases.
- To address the above issues, it is proposed to drive the multiple fans by a single motor. In such a case, a driving shaft extending from the motor is connected to rotation shafts of the multiple fans through gears. The motor is, for example, fixed to a tank of a heat exchanger, which is disposed at an end of a core of the heat exchanger. Such a blower unit is, for example, described in JP-U-62-112470.
- In the blower unit in which the single driving shaft passes through multiple gear boxes to be connected to the rotation shafts of the multiple fans through the gears, if displacement or misalignment occurs between components, such as between the driving shaft and the motor and between the driving shaft and the gear boxes, a connecting portion between the motor and the driving shaft and the gears receive an excess load. Such an excess load is likely to result in deterioration of durability as well as an increase in noise.
- The present invention is made in view of the foregoing matter, and it is an object of the present invention to provide a blower unit for a vehicle having multiple fans driven by a single motor through gears, which is capable of improving durability and reducing noise.
- According to an aspect of the present invention, a blower unit includes a plurality of blowers, a single motor, a driving shaft, gears, gear boxes and a joint. The blowers are arranged in parallel with each other with respect to a flow of air passing through a heat exchanger of a vehicle. The driving shaft extends from the motor and is connected to rotation shafts of the blowers through the gears. The gears are housed in the gear boxes. The driving shaft and the rotation shafts of the blowers are rotatably supported through the gear boxes. The driving shaft is divided into a plurality of shaft parts in a longitudinal direction thereof. The adjacent shaft parts are connected to each other through the joint in the longitudinal direction of the driving shaft.
- Since the driving shaft is divided into the plurality of shaft parts, and the shaft parts are connected through the joint, displacements or misalignment between the components, such as between the driving shaft and the motor and between the driving shaft and the gear boxes, are absorbed. Therefore, durability improves and noise reduces.
- For example, the driving shaft has a connecting portion of the shaft parts at a location between the motor and the blower, which is closer to the motor than the other, and/or a location between the blowers. In such a case, the joint can be disposed at a location without interfering with the blowers. Therefore, the size of the joint can be set flexibly. For example, it is possible to increase the size of the joint. If the size of the joint is increased, the effect of absorbing the displacement or misalignment is improved.
- For example, the driving shaft has connecting portions of the shaft parts at locations adjacent to the gear boxes.
- Other objects, features and advantages of the present invention will become more apparent from the following detailed description made with reference to the accompanying drawings, in which like parts are designated by like reference numbers and in which:
-
FIG. 1 is a perspective view of a blower unit for a vehicle, partly including an exploded view, when viewed from a rear location of the vehicle, such as a downstream location with respect to a flow of air, according to a first embodiment of the present invention; -
FIG. 2 is a schematic cross-sectional view of a blower of the blower unit, when viewed from a top, according to the first embodiment; -
FIG. 3 is a schematic cross-sectional view of the blower unit, when viewed from a top, according to the first embodiment; and -
FIG. 4 is a schematic cross-sectional view of a blower unit, when viewed from a top, according to a second embodiment of the present invention. - A first embodiment of the present invention will now be described with reference to
FIGS. 1 to 3 . In the present embodiment, the present invention is exemplarily employed to a blower unit for a vehicle for generating cooling air for cooling heat exchangers (not shown), such as an engine coolant radiator and a refrigerant radiator. The engine coolant radiator is in communication with an engine coolant circuit of an engine, that is, an internal combustion engine. The engine coolant radiator serves to cool hot engine coolant, which has been heated through the engine. The refrigerant radiator is in communication with a discharge side of a compressor of a refrigerant cycle of a vehicle air conditioner. The refrigerant radiator serves to cool refrigerant, which has been discharged from the compressor. In the present embodiment, the engine coolant radiator is disposed behind the refrigerant radiator with respect to a vehicle front and rear direction. - In the drawing, an up and down arrow, a right and left arrow, and a front and rear arrow denote respective directions when the blower unit is mounted in the vehicle. As shown in
FIG. 1 , the blower unit generally hasblowers 1, afan shroud 2, and a motor device including a single motor (motor body) 3. Theblowers 1 are disposed in parallel with each other behind the engine coolant radiator. For example, theblowers 1 are aligned in a longitudinal direction of a core of the engine coolant radiator. Theblowers 1 are driven by thesingle motor 3. - The
fan shroud 2 is disposed on a rear side of the engine coolant radiator. Thefan shroud 2 is configured to support theblowers 1 and to cover a space between the engine coolant radiator and theblowers 1, thereby to restrict an airflow caused by theblowers 1 from bypassing the refrigerant radiator and the engine coolant radiator. - The
fan shroud 2 includesshroud ring portions 21 and ashroud panel portion 22. Theshroud ring portion 21 each have a cylindrical shape, such as a ring shape. Theshroud panel portion 22 has a predetermined shape connecting the rear side of the engine coolant radiator to theshroud ring portions 21. Theshroud panel portion 22 forms smooth air passages from the rear side of the engine coolant radiator to thering portions 21. In the present embodiment, respective portions of thefan shroud 2, such as theshroud ring portions 21, theshroud panel portion 22 and the like, are integrally formed with each other. Theshroud panel portion 22 has a rectangular outer shape when projected in a flow direction of air. - Each of the
shroud ring portions 21 provides a Venturi air passage space therein. Each of theblowers 1 is disposed in theshroud ring portion 21 such that a predetermined clearance is provided between an inner surface of theshroud ring portion 21 and radial outer edges of first andsecond blades fans shroud ring portion 21, thefans - In the present embodiment, since the two
blowers 1 are arranged in parallel with each other, thefan shroud 2 has twoshroud ring portions 21. The twoshroud ring portions 21 are arranged in parallel with each other at locations corresponding to theblowers 1. - The
motor 3 is fixed to a rear side of theshroud panel portion 22, such as on a downstream side of theshroud panel portion 22 with respect to a flow of air, through abracket 4. Themotor 3 is disposed on a centerline passing through centers of theshroud ring portions 21. - Next, a structure of the
blowers 1 will be described in detail. - As shown in
FIG. 2 , each of theblowers 1 has contra-rotatingfans axial fan 11 and a secondaxial fan 12. The firstaxial fan 11 and the secondaxial fan 12 are disposed in series with respect to the flow of air. That is, the firstaxial fan 11 and the secondaxial fan 12 are arranged such that first andsecond rotation shafts axial fan 11 is disposed on a front side of the secondaxial fan 12 with respect to the vehicle front and rear direction. That is, the firstaxial fan 11 is disposed upstream of the secondaxial fan 12. - The first and second
axial fans axial fans axial fan 11 in a circumferential direction is cancelled by the contra rotation of the secondaxial fan 12. Therefore, kinetic pressure of the turning flow generated at the outlet of the firstaxial fan 11 is recovered as static pressure. Because the static pressure is larger than static pressure generated in a general series of fans, the volume of air passing through the heat exchangers can be increased. - The first
axial fan 11 has afirst boss part 11 b andfirst blades 11 c radially extending from thefirst boss part 11 b. Thefirst boss part 11 b has a tubular shape with a closed end. Thus, thefirst boss part 11 b has a substantially U-shaped cross-section. Thefirst boss part 11 b includes afirst bottom wall 11 d having a circular shape and afirst side wall 11 e extending from an edge of thefirst bottom wall 11 d. Thefirst side wall 11 e is substantially perpendicular to thefirst bottom wall 11 d. Thefirst rotation shaft 11 a extends from the center of thefirst bottom wall 11 d. Thefirst blades 11 c extend from an outer surface of thefirst side wall 11 e. - Likewise, the second
axial fan 12 has asecond boss part 12 b andsecond blades 12 c radially extending from thesecond boss part 12 b. Thesecond boss part 12 b has a tubular shape with a closed end. Thus, thesecond boss part 12 b has a substantially U-shaped cross-section. Thesecond boss part 12 b includes asecond bottom wall 12 d having a circular shape and asecond side wall 12 e extending from an edge of thesecond bottom wall 12 d. Thesecond side wall 12 e is substantially perpendicular to thesecond bottom wall 12 d. Thesecond blades 12 c extend from an outer surface of thesecond side wall 12 e. - The first and second
axial fans second boss parts axial fans second side walls - Driving gears 32 are fixed on a driving
shaft 31, which extends from themotor 3, at locations corresponding to the twoblowers 1. The driving gears 32 are, for example, bevel gears. - In each
blower 1, the first andsecond fans second rotation shafts shaft 31. A first driven gear 11 f is fixed to an end of thefirst rotation shaft 11 a. A second drivengear 12 f is fixed to an end of thesecond rotation shaft 12 a. The first and second driven gears 11 f, 12 f are engaged with thedriving gear 32, respectively. Thus, a driving force generated from themotor 3 is transmitted to the first andsecond rotation shafts shaft 31 and thegears second rotation shafts - A
gear box 5 is disposed in a space provided between the first andsecond boss parts second rotation shafts gear box 5 through first andsecond bearings gear box 5 houses the first and second driven gears 11 f, 12 f as well as thedriving gear 32. Also, thegear box 5 rotatably supports the drivingshaft 31 through abearing 33, similar to the first andsecond rotation shafts - As shown in
FIG. 1 , thegear boxes 5 are supported bystays 23 that are extended in a horizontal direction, such as in a longitudinal direction of the drivingshaft 31, and fixed to thefan shroud 2. In the present embodiment, for example, two stays 23 are arranged parallel to each other and support upper and lower ends of thegear boxes 5. -
FIG. 3 shows a schematic cross-section of the blower unit when viewed from a top. InFIG. 3 , an internal structure of thegear box 5 is not illustrated. In the present embodiment, thefan shroud 2 has the twoshroud ring portions 21 aligned in the longitudinal direction of the drivingshaft 31. Hereinafter, one of theshroud ring portions 21, which is closer to themotor 3 than the other, is referred to as a firstshroud ring portion 21A, and the other, which is further from themotor 3 than the firstshroud ring portion 21A, is referred to as a secondshroud ring portion 21B. - As shown in
FIG. 3 , the drivingshaft 31 is divided into threeshaft parts 310 in the longitudinal direction thereof. Specifically, the drivingshaft 31 is divided at a first location between themotor 3 and the firstshroud ring portion 21A and a second location between the firstshroud ring portion 21A and the secondshroud ring portion 21B, that is, between the twoblowers 1. -
Joints 6 are provided between theadjacent shaft parts 310. Theadjacent shaft parts 310 are connected to each other in the longitudinal direction of the drivingshaft 31 throughjoints 6. That is, thejoints 6 are located between themotor 3 and the firstshroud ring portion 21A and between the firstshroud ring portion 21A and the secondshroud ring portion 21B. For example, each of thejoints 6 is made of a metal, and has a substantially cylindrical shape having an axis coincident with a longitudinal axis of the drivingshaft 31. - The driving
shaft 31 extends in an alignment direction of the twoblowers 1, that is, in a vehicle width direction corresponding to a right and left direction. Thesingle driving shaft 31 is constructed by connecting the threeshaft parts 310 with the twojoints 6 in the alignment direction of the twoblowers 1. - As discussed above, the driving
shaft 31 includes themultiple shaft parts 310, and themultiple shaft parts 310 are connected through thejoints 6. As such, displacement or misalignment between the drivingshaft 31 and themotor 3 and between the drivingshaft 31 and thegear boxes 5 can be absorbed. Accordingly, durability of the blower unit improves, and noise reduces. - In a case where the
joints 6 are located between the opposed first andsecond blades blower 1, it is necessary to provide a predetermined clearance between the first andsecond blades second blades blower 1 is increased in the vehicle front and rear direction, depending on the size of thejoint 6. Further, if a space for mounting the blower unit is limited in an engine compartment of the vehicle, it is necessary to reduce the size of thejoints 6. In such a case, it is difficult to sufficiently achieve the effect of absorbing the displacement or misalignment. - In the present embodiment, on the other hand, the driving
shaft 31 has connecting portions of theadjacent shaft parts 310 at the first location between themotor 3 and the firstshroud ring portion 21A and the second location between the firstshroud ring portion 21A and the secondshroud ring portion 21B. Namely, thejoints 6 are disposed in areas without interfering with the first andsecond blades blowers 1. Accordingly, the size of thejoints 6 can be flexibly decided. For example, the size of thejoints 6 can be increased without considering the clearance between the first andsecond blades - A second embodiment of the present invention will be described with reference to
FIG. 4 . Hereinafter, parts similar to the first embodiment are designated with the same reference numbers, and a description thereof is not repeated. -
FIG. 4 shows a schematic cross-section of the blower unit of the second embodiment when viewed from a top. InFIG. 4 , an internal structure of thegear box 5 is not illustrated. Hereinafter, one of theblowers 1, which is closer to themotor 3 than the other, is referred to as afirst blower 1A, and the other, which is further from themotor 3 than thefirst blower 1B, is referred to as asecond blower 1B. - As shown in
FIG. 4 , the drivingshaft 31 is divided into fiveshaft parts 310 in the longitudinal direction thereof. Specifically, the drivingshaft 31 is divided at a first location between themotor 3 and the firstshroud ring portion 21A, second and third locations, which are on axially opposite sides of thegear box 5 of thefirst blower 1A within the firstshroud ring portion 21A, and a fourth location adjacent to thegear box 5 of thesecond blower 1B within the secondshroud ring portion 21B. The second location is adjacent to thegear box 5 on a side closer to themotor 3, and the third location is adjacent to thegear box 5 on an opposite side further from themotor 3. The fourth location is adjacent to thegear box 5 of thesecond blower 1B on a side closer to themotor 3. - The
joints 6 are provided between theadjacent shaft parts 310. Theadjacent shaft parts 310 are connected to each other through thejoints 6. In the present embodiment, thejoints 6 are disposed at the first location between themotor 3 and the firstshroud ring portion 21A, the second and third locations, which are on axially opposite sides of the first andsecond boss parts first blower 1A, and the fourth location, which is adjacent to the first andsecond boss parts second blower 1B on a side closer to themotor 3. The second and third locations are outside of the first andsecond boss parts first blower 1A. The fourth location is outside of the first andsecond boss parts second blower 1B. - Accordingly, the driving
shaft 31 extending in the alignment direction of the first andsecond blowers shaft parts 310 through the fourjoints 6. - Therefore, displacement or misalignment between the driving
shaft 31 and themotor 3 and between the drivingshaft 31 and thegear boxes 5 are absorbed. Accordingly, the durability of the blower unit improves, and the noise reduces. - In the above embodiments, the present invention is employed to the blower unit in which the two
blowers 1 are aligned in the longitudinal direction of the drivingshaft 31. However, the present invention can be employed to a blower unit in which a single blower is arranged, or three or more than three blowers are arranged. - Further, the connecting portions of the
shaft parts 310 are not limited to the above discussed locations. Also, the number of the connecting portions of theshaft parts 310 and the number of thejoints 6 are not limited to the above described numbers. - For example, in the first embodiment, the driving
shaft 31 may have a connecting portion of theshaft parts 310 at least one of between themotor 3 and the firstshroud ring portion 21A and between the first and secondshroud ring portions shaft 31 may have further another connecting portion of theshaft parts 310 between the first and secondshroud ring portions - The
blower 1 is not limited to have the contra-rotating fans. Theblower 1 may have a single axial fan. - In the above embodiments, the
motor 3 is fixed to thefan shroud 2 through thebracket 4, and thegear boxes 5 are fixed to thefan shroud 2 through the stays 23. However, themotor 3 and thefan shroud 2 may be fixed in various other ways. For example, themotor 3 and thegear boxes 5 can be directly fixed to thefan shroud 2, respectively. - Additional advantages and modifications will readily occur to those skilled in the art. The invention in its broader term is therefore not limited to the specific details, representative apparatus, and illustrative examples shown and described.
