Definitions
- This invention relates generally to heat shields, and more particularly to a mounting and vibration dampening apparatus for mounting a heat shield.
- Vehicles and other equipment that operate via an internal combustion engine contain various components that create extremely high temperature heat. If left unchecked, the heat from the components can have adverse affects on surrounding components.
- an automotive vehicle has an exhaust system including exhaust pipes and catalytic converters which can reach temperatures between 800-1200° Fahrenheit (° F.) or more.
- a thermal barrier often referred to simply as a heat shield
- heat shields are often used within an engine compartment of the vehicle to prevent radiant heat from having adverse affects on surrounding components, electrical lines, and hoses, for example, wherein elevated temperatures are becoming more commonplace due modern engine packages creating cramped environments.
- Heat shields are becoming increasingly important products for insulating the heat, sound and vibration of automobile engines, electric generator engines, parts of exhaust pipes, amongst numerous other applications.
- Such multi-functional heat and vibration dampening shields must often fit into a relatively small space while providing high performance to protect the surrounding parts.
- Heat shields typically comprise one or more layers of material that must be fixed and maintained in position by a mounting bracket.
- the mounting bracket not only plays an important role in fixing the heat shield in position, but is also intended to inhibit the transfer of heat from the heat source to the heat shield, as well as to dampen vibration.
- Known mounting brackets can be complex in construction; relatively bulky and heavy, which in turn adds cost and weight to the vehicle, and further, can allow heat and vibration to affect the performance of the vehicle. More so than ever, cost, weight and performance are main concerns in the production of vehicles, and thus, improvements to positively impact each concern are continually sought.

Description
- This U.S. Divisional patent application claims priority to U.S. Utility patent application Ser. No. 15/134,568, filed Apr. 21, 2016, which claims priority to U.S. Provisional Patent Application No. 62/152,730, filed Apr. 24, 2015, and U.S. Provisional Patent Application No. 62/260,039, filed Nov. 25, 2015, the entire contents of which are incorporated herein by reference.
- This invention relates generally to heat shields, and more particularly to a mounting and vibration dampening apparatus for mounting a heat shield.
- Vehicles and other equipment that operate via an internal combustion engine contain various components that create extremely high temperature heat. If left unchecked, the heat from the components can have adverse affects on surrounding components. For example, an automotive vehicle has an exhaust system including exhaust pipes and catalytic converters which can reach temperatures between 800-1200° Fahrenheit (° F.) or more. As such, it is known to place a thermal barrier, often referred to simply as a heat shield, adjacent the exhaust pipes and/or catalytic converter to prevent radiant heat from impinging adjacent components and from entering a passenger compartment of the vehicle. In addition, heat shields are often used within an engine compartment of the vehicle to prevent radiant heat from having adverse affects on surrounding components, electrical lines, and hoses, for example, wherein elevated temperatures are becoming more commonplace due modern engine packages creating cramped environments.
- Accordingly, heat shields are becoming increasingly important products for insulating the heat, sound and vibration of automobile engines, electric generator engines, parts of exhaust pipes, amongst numerous other applications. Such multi-functional heat and vibration dampening shields must often fit into a relatively small space while providing high performance to protect the surrounding parts. Heat shields typically comprise one or more layers of material that must be fixed and maintained in position by a mounting bracket. The mounting bracket not only plays an important role in fixing the heat shield in position, but is also intended to inhibit the transfer of heat from the heat source to the heat shield, as well as to dampen vibration. Known mounting brackets can be complex in construction; relatively bulky and heavy, which in turn adds cost and weight to the vehicle, and further, can allow heat and vibration to affect the performance of the vehicle. More so than ever, cost, weight and performance are main concerns in the production of vehicles, and thus, improvements to positively impact each concern are continually sought.
- One aspect of the invention provides an isolator for damping heat and vibrations between a heat shield and heat source without a complex construction and without adding significant volume, cost, or weight to the vehicle. The isolator includes a housing surrounding a center opening and extending axially from a first end portion to a second end portion and including an intermediate portion therebetween. The first end portion of the housing extends radially inwardly to form a first annular pocket between the first end portion and the intermediate portion. The second end portion of the housing extends radially outwardly to form a second annular pocket between the second end portion and the intermediate portion. The first annular pocket faces the center opening, and the second annular pocket faces away from the center opening for receiving the heat shield. A washer extends radially from an outer periphery received in the first annular pocket of the housing to the center opening for receiving a fastener to connect the heat shield to the heat source. The washer also includes a plurality of through openings between the outer periphery and the center opening for enhancing vibration dampening and minimizing heat transfer from the heat source to the heat shield.
- Another aspect of the invention includes a heat shield assembly for attachment to a heat source by a fastener. The assembly comprises a heat shield including a through opening presented by an inner periphery; and an isolator received in the through opening of the heat shield for damping heat and vibrations between the heat shield and the heat source. The isolator comprises a housing surrounding a center opening, and the center opening is axially aligned with the through opening of the heat shield. The housing extends axially from a first end portion to a second end portion and includes an intermediate portion therebetween. The first end portion of the housing extends radially inwardly to form a first annular pocket between the first end portion and the intermediate portion. The second end portion of the housing extends radially outwardly to form a second annular pocket between the second end portion and the intermediate portion. The first annular pocket faces the center opening, and the annular pocket faces away from the center opening and receives the inner periphery of the heat shield. A washer extending radially from an outer periphery received in the first annular pocket of the housing to the center opening for receiving the fastener to connect the heat shield to the heat source. The washer includes a plurality of through openings between the outer periphery and the center opening for enhancing vibration dampening and minimizing transfer of heat from the heat source to the heat shield.
- A method of manufacturing an isolator for damping heat and vibrations between a heat shield and heat source is also provided. The method comprises the step of: providing a washer extending radially from an outer periphery to a center opening, the washer including a plurality of through openings between the outer periphery and the center opening for enhancing vibration dampening and minimizing heat transfer from the heat source to the heat shield; and providing a housing surrounding a center opening, the housing extending from a first end portion to a second end portion and including an intermediate portion therebetween. The method further includes bending the housing so that the first end portion extends radially inwardly; disposing the outer periphery of the washer between the first end portion and the intermediate portion of the housing; and bending the housing so that the second end portion extends radially outwardly to form an annular pocket between the second end portion and the intermediate portion, the second annular pocket facing away from the center opening for receiving the heat shield.
- The invention also provides a method of manufacturing a heat shield assembly. The method includes providing a washer extending radially from an outer periphery to a center opening for receiving a fastener to connect the heat shield assembly to the heat source, the washer including a plurality of through openings between the outer periphery and the center opening for enhancing vibration dampening and minimizing heat transfer from the heat source to the heat shield; and providing a housing surrounding a center opening, the housing extending from a first end portion to a second end portion and including an intermediate portion therebetween. The method further includes bending the housing so that the first end portion extends radially inwardly; disposing the outer periphery of the washer between the first end portion and the intermediate portion of the housing; bending the housing so that the second end portion extends radially outwardly; and disposing an inner periphery of a heat shield between the second end portion and the intermediate portion of the housing.

FIG. 1-3 (FIG. 2 is partially assembled) show a heat shield assembly, referred to hereafter asassembly 10, constructed in accordance with one presently preferred embodiment of the invention. Theassembly 10 is constructed to enhance sound insulation in a manner of vibration dampening, to minimize weight, to minimize conductivity of heat from a heat source throughout theassembly 10, and to occupy as small an envelope as possible. Theassembly 10 has a broad array of applicable uses, such as in vehicles having internal combustion engines, construction machinery, and agricultural machinery, by way of example and without limitation. Further, theassembly 10 is economical in manufacture and in assembly and exhibits a long life in use. - The
assembly 10 includes aheat shield 12 and a heat and vibration mounting isolator, referred to hereafter asisolator 14, fixed to one another. Theheat shield 12 can be constructed from one or more layers of material, as desired, and can take on any size, shape and configuration, as desired for the intended application. Theheat shield 12 if provided with a through opening 16 that is bounded by an inner periphery 18 to facilitate fixing theisolator 14 thereto. Theisolator 14 includes awasher 20 and anannular housing 22, also referred to as a strainer. Thewasher 20 has anouter periphery 24 and acenter opening 26 extending about acentral axis 28. Theannular housing 22 extends about thecentral axis 28 through the through opening 16 of theheat shield 12. Theannular housing 22 has opposite first andsecond end portions intermediate portion 34 extending between the first andsecond end portions first end portion 30 is curled radially inwardly toward thecentral axis 28 in overlying relation with theintermediate portion 34 to form a firstannular pocket 36 opening toward thecentral axis 28. The firstannular pocket 36 is bounded on opposite sides by theintermediate portion 34 and thefirst end portion 30, and theouter periphery 24 of thewasher 20 clamped or in other words sandwiched between thefirst end portion 30 and theintermediate portion 34 and fixed in the firstannular pocket 36. Thesecond end portion 32 is curled radially outwardly away from thecentral axis 28 in overlying relation with theintermediate portion 34 to form a secondannular pocket 38 opening away from thecentral axis 28. The secondannular pocket 38 is bounded on opposite sides by theintermediate portion 34 and thesecond end portion 32, and the inner periphery 18 of theheat shield 12 is clamped or in other words sandwiched between thesecond end portion 32 and theintermediate portion 34 and is fixed in the secondannular pocket 38. As such, theheat shield 12 andisolator 14 are permanently fixed to one another. Thewasher 20 of theheat shield assembly 10 is then attached to the heat source, such as the exhaust pipe or catalytic converter, by afastener 42. Thefastener 42 can be a bolt, a screw, or another type of fastening device. Preferably, thewasher 20 is at zero mean stress and will have an applied load under vibration that modulates above and below this mean. Thewasher 20 is typically close to a flat profile, which helps to maximum the strength of the metal material used to form thewasher 20, due to the material not being worked to form its shape. A high yield strength of thewasher 20 maximizes fatigue life. - The
washer 20 of theheat shield assembly 10 is preferably constructed of steel, and more preferably stainless steel; however, it is contemplated that other metals could be used, such as aluminum, for example. Thewasher 20 can be provided with a plurality of throughopenings 40 between theouter periphery 24 and the center opening 26 to enhance vibration dampening, to minimize weight, and to minimize conductivity of thewasher 20 to minimize the transfer of heat from a heat source to theheat shield 12, such as via thefastener 42 that fastens theassembly 10 to a mount location on or adjacent the heat source, such as to portions of an exhaust system, for example. It should be recognized that the throughopenings 40 can be formed having any number of shapes and sizes, such as demonstrated in alternate embodiments constructed in accordance with the invention illustrated inFIGS. 5-12 , wherein the same reference numerals, offset by factors in increments of 100's, are used to identify like features. - In the examples of
FIGS. 1-12 , thewasher 20 presents a circular inner diameter defining thecenter opening 26. However, thewasher 20 could alternatively include a non-circular inner diameter defining thecenter opening 26. For example, thewasher 20 could include a plurality oftabs 41 surrounding and defining thecenter opening 26, wherein eachtab 41 is spaced from the adjacent tab by agroove 43.FIGS. 13 and 14 illustrate an example of thewasher 20 including thetabs 41 andgrooves 43 defining the non-circular inner diameter.FIG. 15 illustrates thewasher 20 with the non-circular inner diameter disposed between other components of theheat shield assembly 10. - In the examples of
FIGS. 3 and 4 , thewasher 20 includes a center ring formed of metal material surrounding the circular ornon-circular center opening 26, and a plurality of rows of throughopenings 40 disposed radially outwardly of the center ring. Each throughopening 40 extends circumferentially along a portion of thewasher 20 and is circumferentially spaced from the adjacent throughopening 40 by a spoke formed of the metal material. Each row of throughopenings 40 is radially spaced from the adjacent row by another ring of the metal material. In the embodiment ofFIGS. 3 and 4 , thewasher 20 includes three rows of throughopenings 40, and each row includes five throughopenings 40 and five spokes. The circumferential length of each spoke is much less than the circumferential length of each throughopening 40. - The
washer 20 can be constructed having any desired thickness, as needed for the intended application, and can be planar, substantially planar, or can include at least onebead 44, also referred to as a stepped region, as shown inFIGS. 16, 19, and 20 . Theouter periphery 24 of thewasher 20 can be formed as being circular or non-circular, symmetrical or non-symmetrical to best enhance vibration dampening, to minimize weight, and to minimize conductivity of the washer. For example, the washers depicted inFIGS. 9 and 10C include radially outwardly extending ears ortabs 46 of differing configurations, wherein theears 46 are substantially the only portion of the washer clamped or sandwiched between thefirst end portion 30 andintermediate portion 34 of thehousing 22, thereby further diminishing the conductive path between thefastener 42, thewasher 20 and thehousing 22, thereby reducing the potential of heat transfer therebetween. Further, as shown inFIG. 12 , the throughopenings 40 can be provided as partially punched openings, thereby havingtangs 48 of material remaining attached to the body of thewasher 20. Thetangs 48 can start from the inner diameter, outer diameter, or another position along thewasher 20, and the number oftangs 48 is not limited to the number of throughopenings 40. Thetangs 48 can also be circumferential, radial, or a combination of both, and are not limited to a planar surface. If provided, thetangs 48 can promote further dampening and can enhance the stiffness of thewasher 20, wherein thetangs 48 can be formed to attain any desired size, shape, orientation and angle of inclination. - The
housing 22 of theheat shield assembly 10 is preferably constructed of aluminum; however, it is contemplated that other metals could be used, such as various forms of steel, for example. Thehousing 22 can be formed being generally serpentine in axial cross-section, and depending on the view, either s or z-shaped, to minimize the envelope occupied by thehousing 22 and to facilitate fixing thehousing 22 to thewasher 20 and theheat shield 12. The serpentine shape is formed as a result of thefirst end portion 30, thesecond end portion 32 and theintermediate portion 34 being folded in stacked, overlying relation with one another, much like an accordion. - According to other example embodiments shown in
FIGS. 15-24 , theheat shield assembly 10 includes acollar member 50 along thecenteropening 26 of thewasher 20 to facilitate mounting of theassembly 10 to the heat source and further reduce the transfer of heat and vibrations from theheat source 10 to theheat shield 12. In the embodiments shown inFIGS. 15-24 , thecollar member 50 includes anupper collar 52 and alower collar 54 maintaining thewasher 20 therebetween. Theupper collar 52 includes aninner neck 56 extending longitudinally along thecenter opening 26. Theupper collar 52 then extends radially outward from theinner neck 56 along an upper surface of thewasher 20. Thelower collar 54 also includes anouter neck 58 extending longitudinally along thecenter opening 26. Thelower collar 54 then extends radially outward from theouter neck 58 along a lower surface of thewasher 20. Theouter neck 58 is disposed radially outwardly of theinner neck 56. An outermost radial end of theupper collar 52 is approximately longitudinally aligned with an outermost radial end of thelower collar 54. Typically, there is some space between thewasher 20 and thecollar member 50, in the axial and/or radial direction, such that thewasher 20 floats between the upper andlower collars FIGS. 15-23 , the upper andlower collars collar member 50 can comprise a single piece including both the upper andlower collars FIG. 24 . - In the embodiments including the
collar member 50, thewasher 20 can include thebead 44, or a plurality ofbeads 44, to control the resistance of float of thecollars washer 20, so that theheat shield assembly 10 is easier to align and attach to the heat source. However, thebeads 44 can also be used in embodiments without thecollar member 50. Thebead 44 minimizes thermal conduction, thus increasing thermal insulating efficiency of theassembly 10. Thebeads 44 can comprise a stepped profile, as shown inFIGS. 16 and 19 , or a dome profile, as shown inFIG. 20 . The dome-shapedbeads 44 can be radially and circumferentially spaced from one another along thewasher 20. Although only a couple bead profiles are shown, thebead 44 or beads can alternatively comprise other profiles, For example, thewasher 20 can include a plurality of angularly, circumferentially spacedbeads 44. Thebead 44 can also be provided in the form of a rib. Abead 44 either circumferentially or radially shaped, or a combination thereof, creates a stiffness change in thewasher 20 and thus enables fine tuning of the design. - The
heat shield assembly 10 can also include a thermally resistant coating applied to thewasher 20 to improve insulation and thus reduce heat transfer from the heat source to theheat shield 12. For example, a ceramic coating can be applied to thewasher 20. - In accordance with another aspect of the invention, a method of constructing a
heat shield assembly 10 is provided. The method includes providing aheat shield 12 having a through opening 16 bounded by an inner periphery 18; providing awasher 20 having anouter periphery 24 and acenter opening 26 extending about acentral axis 28, and providing anannular housing 22 having opposite first andsecond end portions intermediate portion 34 extending between the first andsecond end portions first end portion 30 of thehousing 22 radially inwardly toward thecentral axis 28 in overlying relation with theintermediate portion 34 to form a firstannular pocket 36 opening toward thecentral axis 28 and fixedly capturing theouter periphery 24 of thewasher 20 in the firstannular pocket 36. The method also includes curling thesecond end portion 32 radially outwardly away from thecentral axis 28 in overlying relation with theintermediate portion 34 to form a secondannular pocket 38 opening away from thecentral axis 28 and fixedly capturing the inner periphery 18 of theheat shield 12 in the secondannular pocket 38. - To form the
assembly 10 ofFIGS. 15-24 , the method further includes disposing thewasher 20 between the upper andlower collars housing 22 onto thewasher 20. When thecollar member 50 includes the separate upper andlower collars collars - Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that the invention may be practiced otherwise than as specifically described while still being within the scope of the invention.
