DE19742357A1 - Seat-bank tank with filling connector for motorcycles - Google Patents

Abstract

The seat-bank tank (1) is used in combination with a main tank. It has a flanged locking valve (5) and upholstery (2) round it. The tank has a dividing wall (3) to reduce sloshing. A T-piece (6) joins the two tanks. The vent (4) leads to the tank cap of the main tank. The filling connector (7) is flush with the seat.

Description

So far, to increase the tank volume on motorcycles large-volume individual tanks or additional tanks on the side of the rear offered.

However, some of these fuel tanks have an adverse effect on the cooling air supply, on the high-speed behavior (Spin, deterioration of the drag coefficient) and the handling. In addition, these tanks require additional weight and space. They also make a motorcycle look visually heavy and sluggish.

The invention specified in the claim alleviates many of these Disadvantage.

The bench tank requires little extra weight and Space because the shape and volume of the seat already exist. This form is only made according to motorcycle / two-wheeler type, free space changed under the seat and the desired tank volume or enlarged and manufactured as a hollow chamber shape.

The seat tank can also be in its height (in relation to the original Seat) can be changed, what with a minor Increased seat height, of course, a few liters of additional volume for fuel brings.

If the tank volume achieved as a result is not yet sufficient, the Seat tank increased in width compared to the original seat become. The rear half of the tank can be widened and are even pulled down sideways as a comparison additional side tanks.

Since the original tank can be preserved, there are no negative ones Effects on the cooling air supply or on the Fear high-speed behavior.

Of course, the bench tank can be used in conjunction with a commercially available large-volume tank and / or with rear auxiliary tanks used to achieve even greater amounts of fuel when the corresponding disadvantages are accepted or are negligible.

When considering the handling, an improvement is achieved because in In contrast to the other additional tanks, the bench tank is central and on the other hand the focus is a little lower than one large volume single tank.

In addition, the spilling (back and forth sloshing) of the fuel reduced in the seat tank by installing a partition or avoided if this appears necessary.  

Due to the design, it is not possible for the seat tank to be the deepest Has point for taking the fuel, so both tank halves connected by hoses and T-piece. Every bench Half of the tank should then be fitted with a shut-off valve. This has the advantage that if a fuel hose comes loose or is damaged (e.g. in the event of a fall) or when the bench tank is removed the connecting hose is disconnected, each tank half separately can be shut off and so little fuel leaks.

To connect the bench tank, only a T-piece between the existing fuel line inserted.

The bench tank is also filled and emptied using this T-piece. A tank nozzle on the bench tank can therefore also be omitted if it is not is desired.

If the bench tank is used in conjunction with the original tank, then so you can see the motorcycle / two-wheeler the more tank volume purely on the outside not immediately, it retains its visual appearance and its part slim design.

The seat tank allows the amount of fuel and increase this increases the range of the motorcycle without being too concerned with it Weight, driving characteristics, space and appearance.

The seat tank can be retrofitted for the respective motorcycle type used or installed in series.

Recommended for standard assembly of the bench tank without filler neck it, the connection paths between the tanks with the largest possible Diameter in order to shorten the filling time of the bench tank.

Another advantageous embodiment of the invention is that with smaller motorized two-wheelers such as B. Mopeds / scooters when using the Seat tanks with filler neck the space for the conventional tank can be saved because the fuel quantity in the seat tank is sufficient. This saves weight and additional storage space for tools or even created a home.  

In the drawings, bench tank with filler neck (Sheet 1 / 6-3 / 6) and bench tank (Sheet 4 / 6-6 / 6) are each shown an embodiment of the invention and are in following described in more detail.

The drawing of the bench tank with filler neck (front view sheet 1 of 6 ) shows the combination with the original tank.

Here you can see the shape of the seat tank ( 1 ) with the flanged shut-off valve ( 5 ) and the surrounding upholstery ( 2 ).

This also shows the position and shape of the partition ( 3 ) to reduce spillover and the position of the T-piece ( 6 ) to connect the two tanks. You can also see a possible routing of the seat tank ventilation ( 4 ) to the tank cap of the original tank.

The filler neck ( 7 ) is countersunk so that the tank cap is approximately flush with the upholstery ( 2 ).

The drawing of the bench tank with filler neck (top view, sheet 2 of 6 ) shows a good view of the central partition ( 3 ) to reduce spillover. In addition, the ring-shaped guidance of the seat tank ventilation ( 4 ) consisting of a flat hose around the fuel cap is clearly recognizable, which is only intended to be one possible version that gives more visual appeal than a standard round ventilation hose that runs over the original tank.

However, in the case of the bench tank with filler neck, tank ventilation can be used which leads to the original tank, if the tank ventilation in the Seat tank cap is integrated and the user of the seat tank makes sure that it is before refueling the original tank and before the Always open the shut-off valve for the Seat tank closes so that the fuel level in the original tank does not Influences the level in the seat tank.

The user must also first empty the original tank until the Fuel level is below that of the seat tank and only then is it allowed to Open the shut-off valve for the seat tank so that there is no fuel over the Tank cap ventilation runs out.

Another way to solve this problem is to introduce a Check valve immediately before or after the shut-off valve of the seat Tanks.

The design of the filler neck ( 7 ) and the design of the fuel filler cap with a central web and recessed grips on both sides (but without integrated filler cap ventilation) is shown in this drawing.

The drawing of the bench tank (side view sheet 3 of 6 ) shows the interior shape of the bench tank ( 1 ), the position of the partition ( 3 ) to reduce spillover and the routing of the bench tank ventilation ( 4 ) to the tank cap of the original tank.

The filler neck was not shown because the position and Execution through front view and top view are recognizable.  

The drawing of the bench-tank (front view sheet 4 of 6 ) shows the combination with the original tank.

Here you can see the shape of the seat tank ( 1 ) with the flanged shut-off valve ( 5 ) and the surrounding upholstery ( 2 ). This also shows the position and shape of the partition ( 3 ) to reduce spillover and the position of the T-piece ( 6 ) to connect the two tanks. You can also see a possible routing of the seat tank ventilation ( 4 ) to the tank cap of the original tank.

The drawing of the bench-tank (top view sheet 5 of 6 ) shows a good view of the central partition ( 3 ) to reduce spillover. In addition, the ring-shaped guidance of the seat tank ventilation ( 4 ) consisting of a flat hose around the fuel cap is clearly recognizable, which is only intended to be one possible version that gives more visual appeal than a standard round ventilation hose that runs over the original tank.

The drawing of the bench tank (side view sheet 6 of 6 ) shows the internal shape of the bench tank ( 1 ), the position of the partition ( 3 ) to reduce spillover and the routing of the bench tank ventilation ( 4 ) to the tank cap of the original tank.

Claims (2)

1. Seat tank as an additional tank, which makes it possible to use the available space of the seat as a tank volume and, depending on the version, requires little extra weight and space.
With the bench tank, improvements in terms of appearance, handling and high-speed behavior are achieved compared to conventional additional tanks.
In addition, no additional filler neck is required for the bench tank, as the filling takes place via the existing tank. 2. bench tank according to claim 1, with filler neck as Additional tank or usable as the only tank so that the conventional tank can be saved.
