DETAILED DESCRIPTION
[00015] In the following description, numerous details are set forth to provide a thorough understanding of the embodiments. One skilled in the relevant art will recognize, however, that the techniques described herein can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring certain aspects.
[00016] Typically, fuel from a fuel pump unit is supplied to an engine at a high pressure. Consequently it is essential to ensure superior sealing of the fuel pump unit so as to prevent leakages. Especially, in vehicles using a metallic fuel tank, undulations on the fuel tank raise constraints for achieving sufficient flatness required for mounting the fuel pump unit and for achieving superior sealing. Therefore, a mounting plate which has a machined flat surface is attached to the bottom surface of the fuel tank. The fuel pump unit is attached to the mounting plate along with one or more rubber seals (O rings). The rubber seals are attached to a flange portion of the fuel pump unit. However, even after using the mounting plate, and O rings the fuel leakage issue arises due to minimum operating clearance or gaps being left out when the fuel pump unit being attached to the mounting plate and the fuel tank together along with the rubber seal. Additionally as the fuel tank assembly typically grounded in order to dissipate any static electricity buildup in the various parts of the fuel tank assembly that may contact liquid fuel or gaseous fuel fumes. Traditionally, the fuel tank assembly grounded using a grounding wire. The grounding wire is connected to a grounding point to fully connect the conductive parts of the fuel tank assembly to ground. It is known to provide a grounding point using a dedicated bracket welded on an outer surface of the fuel tank. Furthermore, multiple wires and hoses being routed from the fuel pump unit. These wires including grounding wire tend to flex thereby comes in contact with a cylinder head of the engine. This phenomenon can lead to short circuit, and may entail substantial hazards not only to the vehicle but also to a user thereof. Therefore, to address said issue multiple clamps, dedicated brackets being added to avoid flexing of the wires etc. This technique is less efficient in terms of wiring and results in higher costs and longer assembly times. Importantly, a major disadvantage of the welding the dedicated brackets on the outer surface of the metallic fuel tank is the thermal strains resulting in reduced yield leading to cracks in the fuel tank as fuel tank being made up of thin sheet metal. In such cases, additional rework required to repair the fuel tank using a skilled welding operator which increases the overall manufacturing cost of the vehicle. Further, in saddle type vehicles the fuel tank regarded as being particularly important in terms of appearance. For the fuel tank to be aesthetically pleasing, the welded bracket should preferably not be exposed.
Although these parts like fuel pump unit, a fuel filter, a canister, etc. are necessary, they may each add to the overall weight, space, complexity, and cost of the vehicle. Each of these parts also requires its associated wires, harnesses, connectors, hoses, fasteners, etc. and support frame for routing, and supporting all these elements, further adding weight to the fuel tank assembly of the vehicle. Furthermore, it is well known that covers are affixed to either sides of the fuel tank of the vehicle to protect said fuel tank from damage. The side covers not only protect the fuel tank from damage but also contribute to the overall aesthetic appeal of the motor vehicle. Additionally, said side covers also aid in guiding a running wind or ram air, thereby contributing to the overall aerodynamics of the vehicle. Further, since said side covers also protect other component parts located below the fuel tank. However, side covers in the vehicle keep shaking under both static and dynamic condition as it conventionally mounted using two fasteners on the front and the rear end of the fuel tank using dedicated mount brackets. In order to address said issue it is known to provide a support bracket for either side covers. However, use of dedicated brackets increases the manufacturing and logistics costs. Therefore, it is a challenge for design engineers to reliably mount the fuel pump unit to the fuel tank and at the same time provide grounding, and efficient routing of wires in a densely packed layout.
[00017] Therefore, there is a need to provide a fuel tank assembly for a vehicle overcoming all the above problems and trade-offs as well as overcoming problems of the known art.
[00018] It is an object of the present invention to a structure being configured to tightly secure a fuel pump unit to the fuel tank, and provide a grounding and guiding provision for wires, and support at least one of the side cover on either side, while reducing the overall weight, space requirements, cost, and complexity hereto associated therewith.
