TITLE: “A TOP MOUNT ASSEMBLY FOR A STRUT OF A SUSPENSION SYSTEM”

Name and address of the Applicant:
TATA MOTORS LIMITED, an Indian company having its registered office at Bombay house, 24 Homi Mody Street, Hutatma Chowk, Mumbai 400 001, Maharashtra, INDIA.

Nationality: Indian

The following specification describes the nature of invention and the manner in which it is to be performed.
TECHNICAL FIELD
Present disclosure generally relates to a field of automobile engineering. Particularly but not exclusively, the present disclosure relates to a strut for a suspension system of a vehicle. Further embodiments of the disclosure disclose a top mount assembly for the strut of the suspension system.

BACKGROUND OF THE DISCLOSURE

Suspension and its components play a crucial role in the movement of a vehicle. A vehicle in motion tends to receive undue vibrations due to the contact of wheels on undulations arising from surfaces of the road or terrain. Suspension systems come in various forms and requirement based on the application use of the vehicle. The term ‘suspension system’ is a collective term referring to a system of tires, struts, springs, shock absorbers and linkages that connects the vehicle (particularly, to frame/chassis/Body in white (BIW) of the vehicle) to its wheels and allows relative motion between the two. As an example, light utility vehicles like passenger vehicles, are equipped with softer suspension in order to provide effective traction of the wheels and comfort to the passengers. Heavy transport vehicles such as pick-up trucks, semi-trucks, tipper trucks which are used to carry heavier loads may be equipped with stiffer or harder suspension systems.

Various types of suspension systems are mounted to the vehicle, based on the configuration and requirement. One such configuration of the suspension systems is a strut-based suspension system such, as MacPherson struct-based suspension system. Such MacPherson struct-based suspension system includes a coil spring, which is concentrically positioned around a damper rod. One end of the strut is fixed to the bottom metallic seat, while the other end is fixed to the top mount, which in turn is connected to a frame of the vehicle. When the vehicle experience undulations, the shocks or vibrations are transferred from the axle of the vehicle to the helical spring and the strut, which dampen the vibrations and shocks from being transferred to the frame of the vehicle.

Conventional top mounts for the strut-based suspension system includes a metal insert, which is configured to receive an end of a damper rod and rubber sandwiched between the metal insert and body of the top mount. The rubber aids in attenuating structure borne noise and dampening vibrations of particular frequency range. However, conventional top mount poses limitations in effectively dampening vibrations of wide frequency range, thereby offering an uncomfortable riding dynamic to the passenger, which is undesired.

The present disclosure is directed to overcome one or more limitations stated above and any other limitations associated with the prior arts.

SUMMARY OF THE DISCLOSURE

One or more shortcomings of conventional assemblies are overcome, and additional advantages are provided through the provision of a top mount assembly as claimed in the present disclosure. Additional features and advantages are realized through the techniques of the present disclosure. Other embodiments and aspects of the disclosure are described in detail herein and are considered a part of the claimed disclosure.

In a non-limiting embodiment of the disclosure, a top mount assembly for a strut of a suspension system is disclosed. The top mount assembly includes a damper rod sleeve structured to accommodate a portion of a damper rod of the strut, and an elastic member extending around a portion of the damper rod sleeve.

A second chamber is defined between the inertia track and a bottom surface of the second block. Additionally, the top mount assembly includes a top mount bracket fixed to the second block. The top mount bracket is connectable to a frame of the vehicle. The first chamber and the second chamber are filled with a dampening fluid and are structured to be in fluid communication with each other through the inertia track. The dampening fluid selectively flows between the first chamber and the second chamber, corresponding to frequency and amplitude of vibrations induced on the strut to dampen the induced vibrations.

In an embodiment, the top mount assembly includes a diaphragm disposed in the second block, wherein the diaphragm is structured to change its shape corresponding to amplitude of vibrations induced to alter volume of the dampening fluid in the second chamber.

In an embodiment, the dampening fluid is ethylene glycol.

In another non-limiting embodiment of the disclosure, a strut for suspension system of a vehicle is disclosed. The strut includes a damper rod connectable between a frame and a wheel axle of the vehicle, and a resilient member disposed around the damper rod. Further, the strut includes a top mount assembly positioned at one end of the damper rod. The top mount assembly includes a damper rod sleeve structured to accommodate a portion of a damper rod of the strut, and an elastic member extending around a portion of the damper rod sleeve.

The novel features and characteristic of the disclosure are set forth in the appended claims. The disclosure itself, however, as well as a preferred mode of use, further objectives, and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings. One or more embodiments are now described, by way of example only, with reference to the accompanying drawings wherein like reference numerals represent like elements and in which:

Figure. 1 illustrates a sectional view of a strut for a suspension system in exploded condition, in accordance with an embodiment of the present disclosure.

Figure. 2 illustrates a sectional view of the strut for the suspension system in assembled condition, in accordance with an embodiment of the present disclosure.

The figures depict embodiments of the disclosure for purposes of illustration only. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the disclosure described herein.

DETAILED DESCRIPTION

While the embodiments in the disclosure are subject to various modifications and alternative forms, specific embodiment thereof has been shown by way of example in the figures and will be described below. It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.

It is to be noted that a person skilled in the art would be motivated from the present disclosure and modify various constructions of the top mount assembly for the strut of the suspension system and which may vary from vehicle to vehicle. However, such modifications should be construed within the scope of the disclosure. Accordingly, the drawings show only those specific details that are pertinent to understand the embodiments of the present disclosure, so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having benefit of the description herein.

The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are intended to cover a non-exclusive inclusions, such that a device, system, assembly that comprises a list of components does not include only those components but may include other components not expressly listed or inherent to such system, or assembly, or device. In other words, one or more elements in a system or device proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or device.

Embodiments of the present disclosure disclose a top mount assembly for a strut of a suspension system. Conventional top mounts for a suspension system includes a metal insert, which is configured to receive an end of the strut and rubber sandwiched between the metal insert and a body of the top mount. The rubber aids in attenuating structure borne noise and dampening vibrations of particular frequency range. However, conventional top mount pose limitations in effectively dampening vibrations of different frequency range, thereby offering an uncomfortable riding dynamic to the passenger, which is undesired.

Accordingly, embodiments of the present disclosure disclose, the top mount assembly for the strut of the suspension system. The top mount assembly may be configured to tune itself, to dampen or isolate different frequencies experienced by the vehicle at that instant of time. The top mount assembly may include a damper rod sleeve. The damper rod sleeve may be structured to accommodate a portion of a damper rod of the strut, and an elastic member extending around a portion of the damper rod sleeve. Further, the top mount assembly includes a first block, which is configured to accommodate the portion of the damper rod sleeve, such that a first chamber is defined between the damper rod sleeve and inner surfaces of the first block. Furthermore, the top mount assembly includes an inertia track, which is positioned on the first block, and a second block positioned on the inertia track. A second chamber is defined between the inertia track and a bottom surface of the second block. The first chamber and the second chamber may be filled with a dampening fluid.

The inertia track may be defined with a plurality of conduits to allow flow of the dampening fluid between the first chamber and the second chamber and thus forming a fluid communication between the first chamber and the second chamber. Further, the inertia track may include a plurality of slots, each configured to accommodate at least one decoupler element. The decoupler element may be configured to reciprocate corresponding to flow of the dampening fluid from the first chamber into the plurality of slots.
In an operational embodiment, i.e., when the strut (thus, the damper rod) is induced with the low frequency vibration (thus, high amplitude vibration), the damper rod sleeve may displace upwardly by a certain distance, depending upon the amplitude of the induced vibration. Due to displacement of the damper rod sleeve, substantial amount of dampening fluid from the first chamber flows into the second chamber through an inlet conduit defined in the inertia track. This flow of the dampening fluid from the first chamber to the second chamber and the elastic member around the portion of the damper rod sleeve, facilitates in dampening the low frequency vibrations from being transferred to the frame of the vehicle.
In an embodiment, when the strut (thus, the damper rod) is induced with the high frequency vibration (thus, less amplitude vibration), substantial amount of the dampening fluid may flow from the first chamber into the plurality of slots, because of which the decoupler element reciprocates within the corresponding slot. This reciprocation of decoupler element provides low dynamic stiffness to the damper rod, thereby dampens the high frequency vibrations from being transferred to the frame of the vehicle.

The following paragraphs describe the present disclosure with reference to Figures. 1 to 3. In the Figures, the same element or elements which have similar functions are indicated by the same reference signs. In the figures, vehicle is not illustrated for the purpose of simplicity.
Figures. 1 and 2 are exemplary embodiments of the present disclosure, which illustrates a sectional exploded view and a sectional assembled view of a strut (101) of a suspension system of a vehicle, respectively. The suspension system may be configured to isolate or dampen the vibrations generated due to undulations on the road and other external factors during maneuvering of the vehicle. As seen in Figure. 1, the strut (101) may include a damper rod (104) and a resilient member (103) such as but not limiting to a coil spring, disposed around the damper rod (104). The damper rod (104) may be configured such that, one end of the damper rod (104) may be connected to a frame or body in white (BIW) of the vehicle and other end, opposite to the one end may be connected to a wheel axle [not shown in figures]. Further, the strut (101) may include a top mount assembly (100), which may be positioned on end of the damper rod (104), such that the one end of the damper rod (104) may be connected to the body in white (BIW) of the vehicle through the top mount assembly (100). In an embodiment, the top mount assembly (100) may be configured to dampen the vibrations induced on the strut (101). Further, the top mount assembly (100) is configured to tune itself, depending on frequency or amplitude of the vibrations induced, to dampen or isolate such induced vibrations. In an embodiment, tuning of the top mount assembly (100) may be inferred as adaption of different techniques by the top mount assembly (100), to dampen or isolate the vibrations, depending on the frequency of the vibrations induced on strut (101) of the suspension system, to dampen or isolate the vibrations.
Turning now Figure. 3, which illustrates a sectional view of the top mount assembly (100). The top mount assembly (100) may include a damper rod sleeve (102), which may be structured to accommodate a portion of a damper rod (104) of the strut (101) and an elastic member (117) extending around a portion of the damper rod sleeve (113). In an embodiment, the elastic member (117) may be but not limiting to rubber. Further, the top mount assembly (100) may include a first block (105). The first block (105) may be configured to receive a portion of the damper rod sleeve (102), such that a first chamber (106) may be defined between the damper rod sleeve (102) and inner surfaces of the first block (105). As apparent from Figure. 3, the top mount assembly (100) may further include an inertia track (107), which may be positioned on the first block (105) and a second block (113), which may be positioned on the inertia track (107). As an example, the inertia track (107), the first block (105) and the second block (113) may be connected to each other suitable connecting elements such as but not limiting to fasteners or clamping. In an embodiment, the second block (113) may be positioned on the inertia track (107), such that a second chamber (114) may be defined between the inertia track (107) and a bottom surface of the second block (113).
In an embodiment, the first chamber (106) and the second chamber (114) may be filled with a dampening fluid and are in fluid communication to each other through the inertia track (107). As an example, the dampening fluid may be but not limiting to ethylene glycol.
Further referring to Figure. 3, the inertia track (107) may be defined with a plurality of conduits (108, 109). In an embodiment, the plurality of conduits (018, 109) may include an inlet conduit (108) which may be defined at a first chamber (106) side and an outlet conduit (109) may be defined at a second chamber (114) side. The inlet conduit (108) and the outlet conduit (109) may facilitate flow of the dampening fluid between the first chamber (106) and the second chamber (114) to dampen the vibrations induced on the strut (101). Further, the top mount assembly (100) may include a diaphragm (115), which may be disposed in the second block (113). The diaphragm (115) may be structure to change its shape by displacing up and down, depending on amplitude of the vibrations induced on the strut (101). The change in shape of the diaphragm (115) aids in altering volume of the dampening fluid flowing into the second chamber (114), to dampen or isolate the vibrations of wide frequency range, induced on the strut (101). Additionally, the top mount assembly (100) may include a top mount bracket (116), which may be fixed to the second block (113). The top mount bracket (116) may include a flange portion, which may be defined with a plurality of holes, such that the top mount bracket (116) may facilitate in connecting an end of the strut (101) with the body in white (BIW) of the vehicle.
As apparent from Figure. 3, the inertia track (107) may include a plurality of slots (110). In an illustrated embodiment, the inertia track (107) includes two slots (110), which are parallel to each other. However, the same cannot be construed as a limitation, as the inertia track (107) may include several slots (110) based on the requirement. Each of the plurality of slots (110) may be configured to movably accommodate at least one decoupler element (111). In an embodiment, the decoupler element (111) may be pinged in the corresponding slot and may be configured to reciprocate within the corresponding slot of the plurality of slots (110). Further, each of the plurality of slots (110) may be defined with a plurality of apertures (112), which may be configured to allow flow of the dampening fluid between the first chamber (106) and the corresponding slot of the plurality of slots (110). In an embodiment, corresponding to flow of the dampening fluid between the first chamber (106) and the slot, the decoupler element (111) may reciprocate within the corresponding slot, to dampen or isolate the vibrations induced on the strut (101).
In an operational embodiment, i.e., during manoeuvring of the vehicle, due to road undulation and others external factors vibrations may be induced on the strut (101). Such vibrations induced on the strut (101) may be dampened or isolated from transferring to the vehicle frame. Now, working of the top mount assembly (100) to dampen the vibrations possessing low frequency and vibrations possessing high frequency is described hereinafter. In an embodiment, when the strut (101) [thus, the damper rod (104)] is induced with the low frequency vibration (thus, high amplitude vibration), the damper rod sleeve (102) may displace upwardly by a certain distance, say about 0.7 mm to 1 mm depending upon the amplitude of the induced vibration. Due to displacement of the damper rod sleeve (102), substantial amount of dampening fluid may flow from the first chamber (106) flows into the second chamber (114) through an inlet conduit (108) defined in the inertia track (107). Consequent to the flow of the dampening fluid into the second chamber (114), the diaphragm (115) may change its shape to alter volume of the dampening fluid in the second chamber (114), depending on amplitude of the vibration induced. This flow of the dampening fluid from the first chamber (106) to the second chamber (114) and the elastic member (117) around the portion of the damper rod sleeve (102), dampens the low frequency vibrations.
In an embodiment, when the strut (101) [thus, the damper rod (104)] is induced with the high frequency vibration (thus, less amplitude vibration), substantial amount of the dampening fluid may flow from the first chamber (106) into the plurality of slots (110) through the plurality of apertures (112). This flow of dampening fluid from the first chamber (106) into the plurality of slots (110) may result in the decoupler element (111) to reciprocate within the corresponding slot. This reciprocation of decoupler element (111) provides low dynamic stiffness to the damper rod (104), thereby dampening high frequency vibrations from being transferred to the frame of the vehicle.
In an embodiment, the configuration of the top mount assembly (100) aids in effective dampening of vibrations with wide range of frequencies.
In an embodiment, the top mount assembly (100) is simple on construction, easy to assemble with the strut (101) and may be adapted in the existing struts of the suspension system.
In an embodiment, top mount assembly (100) aids in improving Noise, vibration, and harshness (NVH) and articulation index of the vehicle.
In an embodiment, the top mount assembly (100) facilitates in improving secondary ride quality of the vehicle.

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, and especially in the appended claims (e.g., bodies of the appended claims) 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 following appended claims 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, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms.
