The present invention relates to motorcycles, and more particularly to an additional or auxiliary fuel tank for use with a motorcycle.
Many motorcycles have large engines that consume fuel at a relatively rapid rate. In addition, some motorcycles are designed with relatively small fuel tanks to create a particular appearance. For example, a motorcycle fuel tank may be made thinner and smaller so that more room is created around a motorcycle driver.
The small fuel tank may cause many motorcycles to suffer from a limited operating range, which can be a great inconvenience to a motorcycle rider. When operating in sparsely populated areas, a motorcycle may not have enough range to travel between fuel stations.
Motorcycles typically use saddlebags to store or hold objects. For example a motorcycle driver may use saddlebags to hold various types of luggage or clothing for a trip. Saddlebags are generally positioned on the sides of motorcycles. Saddlebags may be made of leather and they may have a shape that is specific to the motorcycle.
Motorcycle owners frequently spend a significant amount of money and time so that their motorcycle has a specific appearance. They do not wish to add items to their motorcycles that unfavorably alter the appearance of the motorcycle.
What is needed is an additional fuel tank for a motorcycle that can be added to a motorcycle without altering the overall appearance of the motorcycle.
The various embodiments of the present invention may, but do not necessarily, achieve one or more of the following advantages:
provide an auxiliary fuel tank for a motorcycle that can be mounted inside a saddlebag;
provide an auxiliary fuel tank for a motorcycle that can increase the operating range of a motorcycle;
provide an auxiliary fuel tank for a motorcycle that is shaped like a saddlebag;
provide a container for fuel that has a leather-like appearance;
provide an auxiliary fuel tank for a motorcycle that can transfer fuel from the auxiliary tank to a main tank;
provide a pump for an auxiliary fuel tank for a motorcycle that can transfer fuel to and from a main tank and an auxiliary tank; and
provide a fuel filter for an auxiliary fuel tank for a motorcycle.
These and other advantages may be realized by reference to the remaining portions of the specification, claims, and abstract.
In certain embodiments, the present invention relates to an auxiliary fuel tank for a motorcycle that can be mounted in a saddlebag. The fuel tank can include a container that defines a reservoir for holding fuel. The container is shaped such that the container can fit inside a saddlebag. A mounting mechanism is coupled with the container. The mounting mechanism can be connected with the motorcycle in order to support the container and the saddlebag.

Saddlebags 40 may have an interior cavity 41 that is formed by walls 42. A cover 44 may be attached to walls 42 in order to seal or close cavity 41. Straps 46 may be mounted to cover 44 and can be used with a buckle 47 mounted to one of walls 42 in order to retain cover 44 in a closed position. A fuel tank 50 may be mounted or contained by saddlebag 40 within cavity 41.
Fuel tank 50 may have a shape that substantially conforms to the contours of the saddlebag 40 or abuts the sides of the saddlebag. This prevents fuel tank 50 from shifting when the motorcycle is moving.
With reference now to
Outer walls 51 can include a top side 52, raised portion 53, bottom side 54, front side 56, back side 58, left side 60, rounded right side 62 and flat right side 64. Outer walls 51 define a cavity or reservoir 68 inside container 49.
A flange 72 can be located in top side 52 and extend upwardly from top side 52. An opening or fill port 70 may be located in flange 72. Fill port 70 is in fluid communication with reservoir 68 and allows a user to fill reservoir 68 with fuel. A cover or cap 74 may be used to seal fill port 70. Cap 74 may have threads 75 that mate with threads (not shown) on the inside of fill port 70. Cap 74 may be screwed into fill port 70 in order to seal fuel within reservoir 68.
Fuel tank 50 may include several threaded studs 110 that extend from back side 58.
Container 49 can further include a finger channel 80 that is located in back side 58. A tube channel 82 may also be located in back side 58 and may connect with a finger channel 80. A transfer tube 98 may extend through tube channel 82 and finger channel 80.
A pump cavity 86 can extend into container 49 on bottom side 54 and back side 58. A filter cavity 84 can also extend into container 49 on bottom side 54 and back side 58. A drain port 90 may be located in filter cavity 84 along bottom side 54. Drain port 90 can allow fuel to be removed or transferred from reservoir 68.
A fuel pump 92 can be mounted in pump cavity 86 and attached to supports 87 by a bracket 93. Fuel pump 92 can be connected to a source of electrical energy such as a motorcycle battery (not shown) in order to power fuel pump 92. A hose 96 can have one end connected with drain port 90 and the other end connected to a fuel filter 94. Fuel filter 94 may be located in filter cavity 84. A hose 97 may be connected between fuel filter 94 and fuel pump 92. Hoses 96 and 97 allow for fuel filter 94 and fuel pump 92 to be in fluid communication with drain port 90.
Transfer tube 98 has ends 98A and 98B. End 98A is connected to fuel pump 92. End 98B may be connected to a quick disconnect coupling 99. Quick disconnect coupling 99 may be connected to several locations. Quick disconnect coupling 99 can be connected with main fuel tank 26 or may be connected with engine 25 or may be connected with a manifold 120.
Quick disconnect coupling 99 may be used to easily connect and disconnect transfer tube 98. This allows the auxiliary fuel tank 50 to be quickly and easily disconnected and removed from the motorcycle if desired. When auxiliary fuel tank 50 is located inside saddlebag 40, the transfer tube 98 may exit the saddlebag through the main opening of the bag or a small hole may be made in the saddlebag for transfer tube 98. Transfer tube 98 may be used to transfer fuel to another motorcycle. Transfer tube 98 may be connected to the other motorcycle via quick disconnect coupling 99 or it may be inserted into a fill port of the other motorcycle's main fuel tank.
A bracket 100 can have bars 102 that are arranged in a pattern to form bracket 100. Several holes 104 may be located in bars 102. A pair of openings 108 are formed by bars 102. Bracket 100 may be formed from a metal such as steel by a stamping process.
Bracket 100 can be attached to fuel tank 50 using studs 110. Studs 110 can pass through holes 104 and be retained to bracket 100 using a fastener 112 such as a nut. Fuel tank 50 and bracket 100 may be mounted in saddlebag cavity 41. Fuel tank 50 and bracket 100 are placed in cavity 41. Studs 114 (

Manifold 120 can further be in fluid communication with fuel pump 92 through transfer tube 98. Fuel pump 92 is in fluid communication with fuel filter 94 through hose 97 and in fluid communication with auxiliary fuel tank 50 through hose 96. Fuel pump 92 may be connected to a switch 140 through a wire 142. Switch 140 may have to be depressed and held in order to turn fuel pump 92 on, in order to transfer fuel from auxiliary fuel tank 50 to main fuel tank 26.
Switch 140 may be manually operated. In one embodiment, switch 140 is a dead man switch that must be continuously depressed to activate fuel pump 92. This prevents the motorcycle operator from forgetting that fuel pump 92 is on or accidentally activating the pump for a long period, thereby overfilling main fuel tank 26. Switch 140 may be placed near the driver's seat 27 of the motorcycle.
Fuel pump 92 can move fuel between fuel tanks 50 and 26. Fuel pump 92 may be connected to the electrical power system of the motorcycle. A dedicated circuit may be provided for fuel pump 92, including a circuit breaker 152 on the motorcycle's circuit breaker panel (not shown). Fuel pump 92 may be connected to an electrical circuit on the motorcycle. For example, fuel pump 92 may be connected to an engine on/of switch 150, which is on when a motorcycle is running. On/off switch 150 is connected to a power source 154 such as a motorcycle battery. Alternatively, fuel pump 92 may be manually operated.
In one embodiment, the fuel pump 92 is reversible so that fuel may be pumped from the main fuel tank 26 to the auxiliary fuel tank 50. In this embodiment, the user may fill the auxiliary fuel tank 50 by pumping fuel to the auxiliary fuel tank 50 from main fuel tank 26 rather than using the fill port 70. Alternatively, the auxiliary fuel tank 50 may be filled by allowing gravity to fill the tank through fill port 70. A one-way check valve 160 may also be mounted between auxiliary fuel tank 50 and main fuel tank 26, if it is desired for fuel only to flow from auxiliary fuel tank 50 to main fuel tank 26.

A leather covering may be attached to the outer walls 251 of the fuel tank by an adhesive or attachment devices, such as screws, staples or rivets. If attachment devices are used, the walls of the tank may be thicker where the devices are applied to prevent the devices from puncturing the walls of the tank. Alternatively, fuel tank 250 may have an integrally formed surface that looks like leather and has the texture and color of leather.
Auxiliary fuel tank 250 may be mounted to frame 24 using saddlebag bracket 34 (
