DETAILED DESCRIPTION
[00014] The subject matter described herein relates to a fuel tank assembly for a sadle-type motorcycle, according to an embodiment of the present subject matter.
[00015] One of the primary aspect of the two-wheeled vehicle, especially that of a motorcycle lies in enhancing aesthetics of the vehicle. Fuel tank in a motorcycle forms a very major role in imparting aesthetics of the vehicle. Thus, it is important to constantly modify the shape of the fuel tank for varying looks of the vehicle. As the fuel tank is usually made up of sheet metal, the amount of investment in tooling cost for different shapes of the fuel tank is very high. As a result, there is a need to provide plastic or resin covers. Plastic or resin covers ensures that even though the shape of the fuel tank is retained same, the shape of fuel tank covers are modified as per requirements.
[00016] Conventionally, fuel tank covers are formed as a sub-assembly while on the other hand the fuel tank is mounted onto the vehicle frame in assembly line. The cover fuel tank sub-assembly known in the prior art is mounted onto the vehicle frame along with the fuel tank in assembly line. Thus, during servicing of the engine, the cover fuel tank needs to be dismantled from the frame, followed by dismantling the fuel tank from the frame. Such a process is cumbersome and consumes a great amount of serviceable time.
[00017] Typically, known fuel tank assemblies in which fuel tank is provided with a cover fuel tank includes cover fuel tank that is most often made of plastic material. Existing cover fuel tank is either enmolded as a single cover piece or made by joining one or more pieces covering different parts of the fuel tank. Such cover fuel tank is provided on motorcycles in which there are a need to mount various components on the sides or below the fuel tank. Such components that get mounted in the vicinity of the fuel tank has to be covered with the help of the fuel tank cover so that they are protected from external factors such as dust, moisture, water and other intrinsic factors such as heat dissipating from the underlying engine. Moreover, providing the fuel tank cover also makes the two-wheeled vehicle more robust. Further, the fuel tank cover also enhances the aesthetic appeal of the two-wheeler.
[00018] Most often than not, fuel tank assembly of two-wheeled motorcycles having cover fuel tank involves separate and independent mounting of the fuel tank and the cover fuel tank with the main frame of the two-wheeled vehicle. Such mounting of the fuel tank and the cover fuel tank often leads to greater lead time during assembly of the fuel tank assembly to the vehicle. Moreover, such mounting also poses a serious concern during servicing and largely decreases the serviceability aspect of the vehicle as there is a need to dismantle the cover fuel tank before accessing the fuel tank.
[00019] Furthermore, the process of assembling the cover fuel tank over the already assembled fuel tank on the vehicle may lead to alignment related problems. Occurrence of such problems will only increase if the cover fuel tank includes two or more parts assembled together to form the cover fuel tank. Any such alignment related problems may cause accumulation of dust or water particles in any gap that is formed between the cover fuel tank and the fuel tank.
[00020] Typically, location and position of fuel filler opening on the cover fuel tank and the corresponding location and position of fuel cap assembly provided on the fuel tank with respect to the vehicle longitudinal axis is an important factor to be considered in the assembly of the fuel tank on to the two-wheeled motorcycle.
[00021] Existing fuel tank assemblies provided with cover fuel tank parts involve providing the fuel cap assembly at the center of the fuel tank coinciding with the vehicle longitudinal axis. In such fuel tanks, the cover fuel tank includes a centrally provided opening to accommodate the fuel cap assembly protruding upwardly from a top surface of the fuel tank. Such opening may be formed out of two cover parts in case of a cover fuel tank involving two or more parts, or may be formed out of a single cover part in case of cover fuel tank involving a single part or two or more parts. However, the assembly of such a cover fuel tank over the fuel cap assembly protruding out of the fuel tank is tedious and complicated involving several parts, including parts dedicated to ensure alignment between the cover fuel tank and the fuel tank.
[00022] Other than the problems that are mentioned above, the existing fuel tank assemblies provided with cover fuel tank parts also involves heat dissipation related problems. For example, in case of two-wheeled motorcycles provided with vertically aligned internal combustion engine, which is mounted directly below the fuel tank assembly, the enclosure formed by the cover fuel tank of the fuel tank assembly may lead to lesser dissipation of heat from heat zones such as the carburetor or area around the spark plug.
[00023] The fuel tank assembly of the present subject matter is provided to overcome the above stated problems.
[00024] In an embodiment, the present subject matter provides a fuel tank assembly for a saddle-type motorcycle having a fuel tank with an outer layer, an inner layer, and a central chamber formed between the outer layer and the inner layer. The inner layer is disposed substantially encompassing a main tube of the motorcycle. In an embodiment, the fuel tank of the saddle type motorcycle is provided with a fuel cap assembly disposed on a top portion of the outer layer. The fuel cap assembly substantially projects upwardly from the top portion of the outer layer. Further, in an embodiment, the fuel tank assembly of the saddle-type motorcycle includes a cover fuel tank assembly disposed above the fuel tank.
[00025] The cover fuel tank assembly covers at least the outer layer of the fuel tank. The cover fuel tank assembly extending longitudinally from a first end, which is proximal to a head tube of the motorcycle to a second end, which is distal to the head tube. In an embodiment, the fuel cap assembly is offset to a longitudinal axis of the motorcycle. The cover fuel tank assembly includes a first side cover part molded in a draw direction inclined to a vehicle width direction. A second side cover part is provided, which is molded substantially in a draw direction inclined to the vehicle width direction, and a central cover part is provided that is molded substantially in a draw direction along the vehicle bottom direction. In an embodiment, at least one of the first side cover part and the second cover part includes a fuel filler opening capable of receiving the fuel cap assembly.
[00026] Further in an embodiment, the first side cover part and the second side cover part of the saddle-type motorcycle are attached to the fuel tank substantially proximal to the first end of the cover fuel tank assembly. The central part is attached to the fuel tank substantially proximal to the second end of the cover fuel tank assembly.
[00027] In an embodiment the fuel tank includes at least one mounting portion disposed substantially farther from the head tube. The mounting portion has one or more mounting slots for attaching the fuel tank to the main tube. Further, the first side cover part includes a first inner side cover part and a first outer side cover part, and the second side cover part includes a second inner side cover part and a second outer side cover part. In an embodiment, each of the first inner side cover part and the second inner side cover part includes an integrally formed grilled portion disposed substantially facing a vehicle front. Further, in one embodiment, a deflector capable of drawing in atmospheric air and directing towards a spark plug region of internal combustion engine of the motorcycle is mounted to at least one of the first inner side cover part and the second inner side cover part.
[00028] In an embodiment, the deflector is sandwich mounted along with the at least one of the first outer side cover and the second outer side cover and the fuel tank.
[00029] The central cover part includes plurality of snap locators adjoining both the first side cover part and the second side cover part. The snap locators enable snap fitting of the first side cover part and the second cover part with the central cover part. Further, in one embodiment, each of the first side cover part and the second side cover part is capable of receiving a grill cover disposed substantially along a vehicle width direction.
[00030] The present subject matter provides an advantageous embodiment of the fuel tank assembly of the saddle-type motorcycle. For instance, the fuel tank assembly of the present subject matter provides a mounting arrangement that overcomes the problems of the prior art. In an embodiment, the mounting arrangement of fuel tank assembly includes attaching one or more parts of the cover fuel tank together and forming a cover fuel tank sub-assembly, which is then mounted on to the fuel tank body at optimal mounting locations and with minimum number of mounting elements. The fuel tank body mounted with the cover fuel tank sub-assembly forms the fuel tank assembly, which is then assembled to the frame member of the motorcycle during assembly process. The advantageous mounting assembly of the fuel tank and the cover fuel tank ensures that both during the assembly and during service, the fuel tank assembly is assembled and disassembled from the frame member as a single unit. Thus, the serviceability of the fuel tank assembly is greatly enhanced as the construction provided in the present subject matter eliminates the need to dismantle the cover fuel tank before accessing the fuel tank.
[00031] Furthermore, the fuel tank assembly of the present subject matter eliminates alignment related problems as the fuel tank assembly as a whole including the cover fuel tank is mounted with the frame member. Hence, there is no need for adjusting the position of the cover fuel tank over the fuel tank body after assembly on the vehicle frame. Thus, the elimination of alignment related problems also ensures that there are no accumulation of dust or water particles in any gap that is formed between the cover fuel tank and the fuel tank.
[00032] Moreover, the fuel tank assembly of the present subject matter also overcomes the problems relating to heat dissipation of the engine of the motorcycle. In an embodiment, the fuel tank assembly includes a cover fuel tank part having a grilled portion to draw in air during the motion of the vehicle. The cover fuel tank part with the grilled portion is attached to a deflector component, which directs the incoming air towards the spark plug region of the motorcycle, thereby ensuring that the region is maintained under optimal temperature for better vehicle performance.
