TECHNICAL FIELD
The present disclosure relates to a configuration of parking brake cable, Gear shifting cable, vehicle floor and fuel tank and more particularly it relates to the interface between the parking brake lever and gear shifting unit and their cables.
BACKGROUND OF PRESENT DISCLOSURE
The conventional passenger cars in today's scenario are front engine vehicles. The engine parts and transaxle are located below the bonnet. In front engined vehicles gear shifter cables runs towards shifter rod fitted on transaxle from the gear shifter unit mounted inside the passenger compartment near to the driver seat.
Parking brake is normally provided on the rear wheels of the vehicle. The parking brake is actuated by a mechanical linkage comprising of a lever and cables. The parking brake lever is also mounted inside the passenger compartment and in proximity to the driver seat. The parking brake cables are routed from the parking brake lever to rear wheel drum brakes.
Since the cables in the gear shifting linkage and parking brake linkages are running in opposite direction the accommodation of both the linkages is relatively easy.
For a rear mounted engine, accommodation of components like fuel pump, gear shifter unit and parking brake lever becomes difficult as the conventional location of fuel tank is taken by engine. Again, the gear shifter cables have to run towards the rear side along with the parking brake cables and fuel lines. Also, if these cables are routed above the floor, their performance is affected by the application of loads due to passenger foot and luggage inside the vehicle. In smaller vehicles, where the wheel base and track are limited, this becomes a challenging situation.
Hence, there exist needs to develop a configuration of the parking brake cables and gear shifting cables without compromising the passenger's comfort and obtaining improved cable efficiencies.

The parking brake lever (5) is also mounted on the front floor (1) of the vehicle but behind the fuel pump cutout (11). While arranging the gear shifting cables (3) and the parking brake cables (8) more attention is paid for locating the parking brake lever grip (15) and gear shifter knob (16) as per ergonomic requirements. The present disclosure comprises two gear shifting cables (3) emerging out from the gear shifter housing (12) which are routed on both the sides of parking brake lever (5) such that they do not disturb the parking brake lever (5) during its operation. The gear shifting cables (3) are placed in such a manner that both the cables are at equi-distance from the parking brake lever (5). The gear shifting cables (3) exit the

vehicle floor below parking brake adjusting rod (6), through a hole provided on the front floor (1) of the vehicle. A grommet (4) of predefined shape is provided below the parking brake adjustment rod (6) for sealing said hole on the front floor (1) of the vehicle. Also, the grommet (4) helps in spacing the two gear shifting cables (3) equally with respect to vehicle centerline (17). An optimized fuel pump cutout (11) is provided in the vehicle front floor (1) such that the fuel pump (14) can be easily removed for servicing by applying parking brake lever (5).
Further in the present disclosure the parking brake adjustment rod (6) is riveted to the parking brake lever (5) for applying brake. An equalizer (7) mounted on the parking brake adjustment rod (6) holds two parking brake cables (8) at equi-distance with respect to vehicle centerline (17). When parking brake lever (5) is operated for applying brake, the equalizer provided on the parking brake adjustment rod (6) moves towards the vehicle front (19) along the length of the adjuster rod (6).
In one embodiment the present disclosure is designed to accommodate the parking brake lever (5) and the gear shift unit (2) within the limited space available for a rear mounted engine. The present disclosure provides the configuration to route both the parking brake cables (8) as well as gear shifting cables (3) towards the rear end of the vehicle. And effort is made to route both the cables below the vehicle floor (1) to achieve better performance and passenger comfort.
In one embodiment of the present disclosure provides a smooth routing for gear shifting cables (3) and parking brake cables (8) to achieve better load and stroke efficiency. And the commonality of parts between Left Hand Drive and Right Hand Drive version vehicle is easily achieved by using this arrangement. Also, the present disclosure locates the parking brake lever (5) behind the fuel pump cutout (11) for easy fuel pump (14) serviceability without compromising the ergonomic requirements.
In the present disclosure the parking brake cables (8) are mounted on the front floor (1) just before the front floor joinery (13) using the parking brake cable abutment (9). This mounting ensures that the rear passenger's leg room is not compromised and thus the passenger comfort is maintained. The above arrangement also allows smooth cable routing which results in better cable efficiencies.

Thus the present disclosed configuration provides an improved and smooth routing of both the gear shifting cables (3) and the parking brake cables (8). Further this arrangement improves the load and stroke efficiency of the cables. Also, the commonality of parts for Left Hand Drive and Right Hand Drive vehicles can be achieved by mounting the gear shifting lever (3) and the parking brake lever (5) in the vehicle centerline.
The foregoing description is a specific embodiment of the present invention. It should be appreciated that this embodiment is described for purpose of illustration only, and that numerous alterations and modifications may be practiced by those skilled in the art without departing from the spirit and scope of the invention. It is intended that all such modifications and alterations be included insofar as they come within the scope of the invention as claimed or the equivalents thereof.
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, 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. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
