, Description:TECHNICAL FIELD

Present disclosure, in general, relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to vibration dampers. Further, embodiments of the present disclosure relates to a portable vibration damper for a rotating shaft in a vehicle.

BACKGROUND OF THE INVENTION

High speeds in vehicles lead to lots of vibrations and kickbacks which are directly transferred from the wheels to other components in the vehicle. The vehicle generally includes an engine that is connected to a crankshaft. The crankshaft may transmit the kinetic energy generated by the engine to a transmission unit. The transmission unit may further transmit the energy to the wheels of the vehicle. The crankshaft is susceptible to torsional vibrations having a frequency of vibration that is a natural multiple of the shaft’s angular velocity. These vibrations arise in the engine and are a result of periodic combustion in the engine. These vibrations are undesirable due to associated noise and equipment fatigue. The vibrations generated are often transmitted to the crankshaft of the vehicle. Since the crankshaft transmits energy from the engine to the transmission unit of the vehicle, eliminating torsional vibration in the crankshaft is crucial. The crankshaft being subjected to vibrations over a prolonged period of time may result in premature failure. Further, several other components that are connected to the crankshaft may also fail prematurely due to the vibrations transmitted from the crankshaft. The conventional torsional vibration dampers are custom designed to be adapted for a specific crankshaft. Consequently, a new torsional vibration damper is to be designed and developed for any new crankshaft assembly and for a newly developed engine. Therefore, the overall development costs of a vehicle increases. Further, the vibration damper that is connectable to a particular crankshaft may only be used for replacement. Consequently, a wide variety of vibration dampers are required to be manufactured where each of the vibration damper is suitable for a particular crankshaft assembly or drive shaft assembly.

The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional configuration of crankshafts in the engine.

Fig. 1 and Fig. 2 illustrates a side view and an exploded view of vibration damper (100) respectively, for a vehicle. The vibration damper (100) may include a housing (10). The housing (10) may be defined by a first section (1) and a section (2). The second section (2) may be defined by a diameter that is smaller than a diameter of the first section (1). The second section (2) may protrude outwardly from the first section (1). Further, the second section (2) may be defined as a depressed region with regards to the first section (1). The second section (2) may be depressed from the first section (1) for a predetermined thickness. The configuration of the first section (1) and the second section (2) may define a chamber (5) in between the first section (1) and the second section (2). Further, the pre-determined thickness of the depressed region may herein form the circumference of the second section (2). The pre-determined thickness forms the circumference of the second section (2) that may be equivalent to the thickness of the chamber (5) defined between the first section (1) and the second section (2). The second section (2) may also be defined by a first surface (11) which is an inner surface of the second section (2).

In an embodiment, the above disclosed housing (10) with the first section (1) and the second section (2) may be defined by forming a plate and thereby defining the chamber (5). In an embodiment, the housing (10) may be defined by welding the first section (1) with the second section (2). The above-disclosed configuration of the housing (10) must not be limited to be formed by stamping or welding. Any known processes may be employed for defining the housing (10).

The housing (10) may further accommodate a damper (3) within the chamber (5) and a damper ring (4) may be concentrically positioned on the damper (3). The damper (3) may be accommodated inside the chamber (5) to abut the circumference of the second section (2). The damper (3) may also be positioned to lie proximal to the first surface (11) of the second section (2). Further, the damper ring (4) may also be positioned inside the chamber (5). The damper ring (4) may be positioned to abut the inner surface of the damper (3) and may be positioned to lie proximal to the first surface (11) of the second section (2).

In an embodiment, the damper (3) may be made of any vibration attenuating material including but not limited to at least one of nitrile rubber, ethylene propylene diene monomer, ethylene acrylic elastomers. The damper ring (4) may be made of material including but not limited to steel. The damper ring (4) may be a ferrous ring and may be manufactured by any process including but not limited to casting. The thickness of the damper (3) may be dependent on the frequency of the vibration that is to be dampened. In an embodiment, the damper ring (4) may be of any shape including but not limited to a ring-shaped member. In an embodiment, the damper (3) and the damper ring (4) may be configured with a material which has a pre-determined natural frequency which is configured to dampen or attenuate the vibration in a particular frequency range. In an embodiment, the thickness of the damper (3) is directly proportional to the frequency of the vibration that is to be dampened. For instance, a low thickness damper (3) may be used for dampening vibrations of low frequency and a high thickness damper (3) may be used for dampening vibrations of greater frequency.

The first section (1) of the housing (10) may include at least one connector (6). The at least one connector (6) may be employed to connect the housing (10) to a region where vibrations are to be dampened. For instance, the housing (10) may be coupled to one of the ends of a crankshaft (9) by the at least one connector (6) for dampening the torsional vibrations from the crankshaft (9).

Fig. 3 illustrates a system for dampening vibrations in a drive unit of a vehicle. One end of a crankshaft (9) in an engine may be connected to a flywheel whereas, the other end of the crankshaft (9) may be connected to at least one pulley (7) [hereinafter referred to as the pulley]. Further, the end of the crankshaft (9) that is connected to the pulley (7) may include a sprocket (12). The sprocket (12) may be connected to the end of the crankshaft (9) and may further be secured to the crankshaft (9) by a bolt (13). The end of the crankshaft (9) accommodating the pulley (7) may be defined by an aperture for receiving the bolt (13). The sprocket (12) may be positioned on the crankshaft (9) to enclose the end of the crankshaft (9) that accommodated the pulley (7). Further, the sprocket (12) may also be defined with a central hole. When the sprocket (12) is positioned on the crankshaft (9), the central hole of the sprocket (12) may be defined to lie along the same axis as that of the aperture defined to the crankshaft (9). The bolt (13) may be inserted through the central hole of the sprocket (12) and the aperture of the crankshaft (9) for fixedly connecting the sprocket (12) to the crankshaft (9). Further, one end of the sprocket (12) is connected to the crankshaft (9) and the other end of the sprocket (12) may be fixedly connected to an adapter (8). The adapter (8) may be defined by a first portion (8a) and a second portion (8b). The thickness of the second portion (8b) may be significantly greater than the thickness of the first portion (8a). The first portion (8a) of the adapter (8) may be fixedly connected to the sprocket (12) by at least one fastener (14) [hereinafter referred to as the fasteners]. Further, the second portion (8b) of the adapter (8) may be fixedly connected to the housing (10) of the vibration damper by the at least one connector (6).

The second portion (8b) of the adapter (8) may also accommodate the pulley (7). The pulley (7) may be positioned on the circumference of the second portion (8b) of the adapter (8). The rotation of the crankshaft (9) may cause the sprocket (12) and the adapter (8) to rotate. The pulley (7) that is positioned on the adapter (8) may subsequently rotate due to the rotation of the adapter (8). Further, the housing (10) that is connected to the adapter (8) also rotates and attenuates or dampens the vibrations from the crankshaft (9). In an embodiment, the sprocket (12) and the adapter (8) are of material which dampen the vibrations from the crankshaft (9).

In an embodiment, the above disclosed vibration damper (100) may be configured to other rotating shafts including but not limited to crankshafts (9). The vibration damper (100) may be configured to other components to dampen vibrations.

In an embodiment, the adapter (8) along with the vibration damper (100) may attenuate or dampen the torsional vibrations from the crankshaft (9). The vibration damper (100) may also dampen the vibrations in the crankshaft (9) which are generated due to inertia or acceleration of the vehicle.

In an embodiment, the adapter (8) along with the vibration damper (100) may be retro fitted onto any of the existing crankshaft assemblies. In an embodiment, the adapter (8) and the vibration damper (100) are adaptable to the crankshafts (9) or varying sizes and configurations. assemblies. Consequently, a custom vibration damper may not be required for crankshafts (9) of different sizes. The adapter (8) and the vibration damper (100) may be used across multiple engines and vehicles. Thus, design and development costs are reduced drastically. In an embodiment, the dampening of vibrations from the crankshaft (9) prevents the pre-mature failure of the crankshaft and the other components connected to the crankshaft (9).

Equivalents

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding the description may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."

While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated in the description.
