    Field of Invention
    [001] The invention relates to an insulating decoupler, and, more particularly, to an insulating decoupler in which a torsion spring engaged between the pulley and the unidirectional clutch to resiliently couple the pulley to the mechanical axis, and the pulley directly non-resiliently coupled to the mechanical shaft in a temporary pre-terminated loaded condition. Background of the Invention
    [002] It is common to use serpentine accessory drive systems in motor vehicles to drive engine accessories. A typical serpentine drive system includes a driving pulley on the crankshaft of a vehicle's internal combustion engine, a series of driven pulleys for accessories and a multi-ribbed belt geared around the driven and driven pulleys. An advantage of the serpentine drive is that, thanks to the provision of an automatic belt tensioner on the belt, it is possible to mount the accessories in a fixed way.
    [003] The driving pulley establishes a highly dynamic load on the belt. This high dynamic load is due to the variable torque output characteristics of the internal combustion engines. Under this circumstance, the tensioner is not able to accommodate all variable torque characteristics and changes in belt load caused by variable torque. The result can be noise and reduced belt life due to instant sliding of the belt.
    [004] US patent number 6,083,130 (2000), representative of the state of the art, discloses a serpentine belt drive system for a motor vehicle comprising a drive assembly including an internal combustion engine containing a mechanical output shaft with a driving pulley in it capable of rotating around a geometric axis of the driving pulley. Each of a sequence of connected assemblies has a driven pulley capable of rotating around a geometric axis parallel to the geometric axis of the driving pulley and a serpentine belt mounted in cooperation with the driving pulley and the pulleys moved in a sequence that corresponds to the sequence of the moved sets when related to the direction of movement of the belt to make said moved pulleys rotate in response to the rotation of the driving pulley. The sequence of driven assemblies includes an alternator assembly including a mechanical alternator shaft mounted for rotation about a geometric axis of the mechanical axis. A hub structure is fixedly loaded by the alternator's mechanical axis for rotation with the alternator around the geometric axis of the mechanical axis. A spring mechanism and one-way clutch couple the alternator pulley to the hub structure. The unidirectional spring and clutch mechanism comprises a separately formed resilient spring member and connected in series to a unidirectional clutch member. The resilient spring member is constructed and configured to transmit the driven rotation movements from the alternator pulley through the serpentine belt to the hub structure, so that the alternator's mechanical axis is rotated in the same direction as the alternator pulley while it is capable of instantaneous relative resilient movements in opposite directions in relation to the alternator pulley during its rotational rotation. The unidirectional fill member is constructed and configured to allow the hub structure, and therefore the alternator's mechanical shaft, to rotate at a speed greater than the rotation speed of the alternator's pulley when the speed of the mechanical shaft of engine output is decelerated to a level sufficient to establish the torque between the alternator pulley and the hub structure to a predetermined negative level.
    [005] What is needed is an isolating decoupler comprising a torsion spring coupled between the pulley and the unidirectional clutch to resiliently couple the pulley to the mechanical shaft, and the pulley directly coupled in a non-resilient manner to the mechanical shaft in a temporary predetermined loaded condition. The present invention addresses this need. Summary of the Invention
    [006] The primary aspect of the invention is to offer an insulating decoupler comprising a torsion spring engaged between the pulley and the unidirectional clutch to resiliently couple the pulley to the mechanical axis, and the pulley directly coupled in a non-resilient manner to the mechanical axis in a temporary predetermined loaded condition.
    [007] Other aspects of the invention will be demonstrated or will become evident in the following description of the invention and in the attached drawings.
    [008] The invention comprises an isolating uncoupler comprising a pulley, a mechanical shaft, a bushing slidably coupled with the pulley and slidably engaged with the mechanical shaft, the pulley seated on the mechanical shaft by a bearing, a clutch unidirectional fixed to the mechanical axis and coupled to the bushing, whereby the bushing rotates synchronously with the unidirectional clutch, a torsion spring engaged between the pulley and the unidirectional clutch to resiliently couple the pulley to the mechanical axis, and the pulley directly can be non-resiliently coupled to the mechanical shaft in a temporary predetermined loaded condition.

    [017] Fig. 1 is a sectional view of the isolating uncoupler. The isolating decoupler 100 comprises a pulley 3 containing a surface with multiple ribs 31. The pulley 3 is rotatably mounted on the outer race 81 of a ball bearing 8. The bearing 8 can also comprise a sleeve, bushing, needle or other suitable form of bearing.
    [018] A spring retainer 6 is snapped onto the pulley 3. One end 41 of the torsion spring 4 engages with the spring retainer 6. The other end 42 of the torsion spring 4 engages with the plastic bushing 2. A bushing 2 is arranged between the pulley 3 and the mechanical axis 11.
    [019] One-way clutch 7 is a roller clutch with a cage and an inner and outer race. The inside diameter of the one-way clutch is formed by the mechanical shaft 11. A clutch bracket 5 is snapped into the outer race of the one-way clutch 71.
    [020] The clutch support 5 comprises two projections 51 which extend radially from the support in a direction normal to a rotating axis A-A. Each projection 51 cooperatively engages a recess 2 in the bushing 2, through which the torque is transmitted. The engagement of the tabs 51 on the recesses 22 in this way causes the rotation movement of the bushing 2 to be controlled by the unidirectional clutch 7, therefore, the bushing 2 rotates synchronously with the clutch support 5 and the unidirectional clutch 7.
    [021] The bushing 2 is axially locked on the axis 11 between the cover 1 and the spring 42. The spring 42 presses the clutch support 5, and thus the projections 51 into the bushing 2. The other end of the spring 42 is attached to the spring retainer 6. The isolating decoupler is covered by an outer end cover 1 to prevent the entry of debris into the device. An axial position of the pulley on an alternator mechanical shaft (AS) can be adjusted by a spacer 9. The bushing 2 can comprise any low-friction plastic material known in the art.
    [022] Torque is transmitted from a belt (not shown) to pulley 3. From pulley 3, torque is transmitted to spring retainer 6, then to torsion spring 4, then to bushing 2 and then for the unidirectional clutch bracket 5 and then for the unidirectional clutch 7, going to the mechanical shaft 11 and, at the end, to an accessory mechanical shaft, such as an alternator mechanical shaft AS.
    [023] In operation, the torque is transmitted resiliently by spring 4 and is loaded by twisting in the direction of unwinding. During torque inversions due to the inertia of the driven accessory, the driven mechanical shaft 11 will tend to pass the pulley 3. Before there is a significant excess, the torsion spring 4 will discharge itself to its neutral (unloaded) position. After the spring 4 is unloaded, the mechanical accessory shaft that is connected to the mechanical shaft 11 is disconnected from the clutch bracket 5 by the unidirectional clutch 7.
    [024] The torsion spring 4 cannot be loaded in the opposite (winding) direction from the loading direction because each end 41, 42 of the spring 4 would disengage from its respective engagement with part 26 and part 64.
    [025] The torsion spring 4 is slightly preloaded or compressed between the spring retainer 6 and the bushing 2 to generate a predetermined amount of damping to limit the relative movement between the device components.
    [026] The unidirectional clutch 7 is a unidirectional roller clutch that has no bearing support between the inner and outer raceways. The absence of bearing support between the inner and outer races makes the design smaller, cheaper and lighter. For example, unidirectional clutch 7 is available from SBF or NTN Corporation, located at 1-3-17, Kyomachibori, Nishi-ku, Osaka-shi, Osaka 550-0003 Japan, using HF or HFL style clutches. In the present embodiment, the manufacturer is Suzhou Bearing Factory (SBF) and the part number is HF2016.
    [027] In addition, bushing 2 has internal bearing friction surfaces 24 and external bearing 21. The external bearing surface 21 engages in a sliding way with the surface 32 of the pulley 3. The surface 21 functions during the drive mode. insulation, that is, when the torsion spring 4 is loaded, the pulley 3 with the spring retainer 6, and thus the pulley 3, can move in relation to the bushing 2.
    [028] The cover surface 16 engages by friction on the surface of the bushing 27. The friction engagement between the surface 16 and the surface 27 provides a predetermined amount of damping, so that, during a torque inversion, the spring 4 remains seated between part 64 and part 26. This, in turn, prevents noise that could otherwise be caused by the relative movement of the spring in the device between bushing 2 and spring retainer 6.
    [029] During the super-override (touch inversion) mode, the surface of the internal bearing 24 of the bushing 2 has a sliding engagement with the mechanical shaft 11, so that the mechanical shaft 11 can “exceed” the bushing 2 and therefore, the pulley 3. In this way, the mechanical axis 11 and the bushing 2 have relative rotation movement. The separation of the friction surfaces, in this way, reduces the frictional load, the wear and the accumulation of heat in the isolating uncoupler.
    [030] The device additionally comprises stops that limit the spring unwinding during the loaded operation to avoid overloading the spring. The stops are located between the clutch support 5 and the spring retainer 6, namely, the protrusions of the spring retainer 61 engage cooperatively with the protrusion parts 52 in an overload condition. Under conditions of normal operating torque and normal loading, each projection 61 is not in contact with a projection 52. However, during overloading, spring 4 is unwound and each projection 61 engages with a projection 52, thus coupling the pulley 3 to the mechanical axis 11 in a direct and non-resilient manner, in fact bypassing the spring 4 and the unidirectional clutch 7. For example, such overload conditions may be present during engine acceleration conditions.
    [031] Spring 4 is also preloaded by a small angle to prevent spring 4 from leaving its seat 25 on bushing 2 and spring retainer 6. The preload angle is approximately 5 degrees, which equates to a torque of approximately 1 to 2 Nm. In this “no load” condition, the projection 61 rests on a projection 52, see Fig. 5, thus causing the preload.
    [032] Figure 2 is an exploded view of the isolating decoupler. The outer surface 21 slidably engages an inner surface 32 of the pulley 3. The end 41 meets the end portion 64.
    [033] A pressure ring 10 holds the bushing 2 on the mechanical shaft 11. The cover 1 is fitted under pressure on an edge 33 of the pulley 3.
    [034] Figure 3 is a perspective view of the bushing. The inner surface 24 slides slidingly to an outer surface of the mechanical shaft 11. Each recess 22 receives a protrusion 64. A spiral of the spring 4 rests on the surface 25. The end 42 rests on the end part 26.
    [035] Figure 4 is an end view of the isolating decoupler. The protrusions 61 on the spring retainer 6 engage with cooperative receiving parts, or gaps, 53 on the clutch bracket 5. The spring retainer 6 is rotatably movable relative to the clutch bracket 5 to accommodate normal load fluctuations, as well as torque inversions.
    [036] Figure 5 is a perspective view of Figure 4. The projection 61 is illustrated by leaning on the projection 52 in the unloaded condition due to the slight preload of the spring. As the insulator is loaded and the spring 4 is unwound, the ledge 61 will move away from the ledge 52 to which it engages in the unloaded condition. In the case of an overload condition, each projection 61, by the relative rotation of the spring retainer 6 in relation to the clutch bracket 5, will come in contact with the next successive projection 52. Each projection 61 moves inside the projection 52 between the projections 52. Namely, the first projection 61 and the second projection 52 can be engaged cooperatively, whereby a rotational range of motion of the spring retaining member 6 with respect to the unidirectional clutch support 5 is limited between a first position without load and the second overloaded position, in which the pulley is able to be coupled directly temporarily to the mechanical axis in the condition of maximum overload by direct contact of the projection 61 with the projection 52.
    [037] Figure 6 is a perspective view of the spring retainer. The spring retainer comprises projections 61 that extend radially inward. The member 62 comprises a projecting surface that supports a spring spiral. The inclined part 63 supports a spiral of the spring 4. The end 41 of the spring 4 rests against the ex-tremor part 64.
    [038] Figure 7 is a perspective view of the clutch support. The clutch support 5 is snapped into an outer race of the one-way clutch 7. The clutch support 5 comprises protruding parts 52 that extend in an axial direction.
    [039] The receiving parts 53 are arranged between the protruding parts 52 and defined by them. The circumferential length CL of each part 53 is greater than the width W of each projection 61. This allows for a certain relative rotary movement between the spring retainer 6 and the clutch support 5 during normal operation and torque inversions, that is, the first projection 52 and the second projection 61 are engaged cooperatively, whereby a rotational range of motion of the unidirectional clutch support 5 with respect to the spring retaining member 6 is limited. In addition, this configuration allows the torsion spring 4 to be temporarily rotatably disengaged from the one-way clutch 7 between a first position and a second position, as determined by the engagement of the projections 53 and 61. During the steady state, the operation of zero acceleration of each projection 61 is located substantially centrally on each recess 53 between each projection 52.
    [040] Although a form of the invention has been described here, it will be obvious to those skilled in the art that variations may be made in the construction and in the relationship of the parts without departing from the spirit and scope of the invention described here.
