Description

EFI motorcycle fuel tank

technical field

The utility model belongs to the technical field of fuel supply for motorcycles, in particular to a fuel tank for electric spray motorcycles.

Background technique

At present, the fuel tank of the motorcycle mainly includes the upper shell of the fuel tank and the lower tank of the fuel tank. The chamber is equipped with an oil pipe in the lower casing of the fuel tank, and one end of the oil pipe passes through the lower casing of the fuel tank to lead oil to the engine. With the development of motorcycle EFI technology, it is necessary to install an oil pump on the tank body of the motorcycle, and the oil pump extracts the fuel in the fuel tank to provide fuel for the engine. However, the body of the existing motorcycle is very compact and cannot be installed on the fuel tank. To install the oil pump, to realize the transformation of motorcycle EFI technology, the motorcycle body has to be redesigned, which increases the cost of motorcycle transformation.

The disadvantage of the prior art is that the body structure of the motorcycle is very compact, and an oil pump cannot be installed on the fuel tank, which is unfavorable for the technical transformation of the electric fuel injection system of the motorcycle.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide a fuel tank of an electric jet motorcycle that can be installed with an oil pump, and can maintain the original body structure of the motorcycle.

The technical scheme of the utility model is as follows: a fuel tank of an electric jet motorcycle, including an upper casing of the fuel tank and a lower tank body, wherein an oil pipe is installed in the lower tank body of the fuel tank, and one end of the oil pipe passes through the lower tank body of the fuel tank outward For oil introduction, the upper casing of the fuel tank is welded on the upper end wall of the lower casing of the fuel tank. .

The oil pump is installed on the upper end wall of the lower box body of the fuel tank, which saves the peripheral space of the fuel tank, maintains the original motorcycle body structure, and is easy and reliable to install.

A reinforcing plate is welded on the upper end wall of the lower box of the fuel tank, and the oil pump is fixed on the reinforcing plate through bolts passing through the lower box of the fuel tank and the reinforcing plate, and the output pipe of the oil pump passes through the reinforcing plate It communicates with the oil pipe in the lower casing of the fuel tank with the upper end wall.

The thickness of the existing upper end wall is limited and cannot support the oil pump. For this reason, a reinforcement plate is welded around the installation through hole of the oil pump to make it the installation interface of the oil pump. The reinforcement plate is an oval ring plate, and the reinforcement plate and the upper end wall The threaded through holes, the distribution of the oval ring plate and the threaded through holes are adapted to the installation size of the oil pump, which is convenient for the stable and reliable installation of the oil pump.

Beneficial effects: the utility model provides a fuel tank of an electric jet motorcycle that can be stably and reliably installed with an oil pump, can maintain the original body structure of the motorcycle, reduces the cost of motorcycle electric jet technology transformation, and is easy and reliable to install.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Fig. 3, the utility model provides a fuel tank of an EFI motorcycle, which is provided with an upper casing 1 of the fuel tank, a lower casing 2 of the fuel tank and an oil pump 4, wherein an oil pipe 5 is installed in the lower casing 2 of the fuel tank, and the oil pipe 5 One end passes through the lower box body 2 of the fuel tank to lead oil outward, the upper end wall 2a of the lower box body 2 of the fuel tank is welded on the upper end wall 2a of the lower tank body 2, and the upper end wall 2a of the lower box body 2 of the fuel tank is installed An oil pump 4, the oil tank upper casing 1 is covered outside the oil pump 4 .

As shown in Figures 1, 2 and 3, a reinforcing plate 3 is welded on the upper end wall 2a of the lower box body 2 of the fuel tank, and the oil pump 4 is fixed on the On the reinforcing plate 3, the output pipe 4a of the oil pump 4 passes through the reinforcing plate 3 and the upper end wall 2a and communicates with the oil pipe 5 in the lower box body 2 of the fuel tank.

Its working principle: as shown in Figure 3, the oil pump 4 is installed on the upper end wall 2a of the lower box body 2 of the fuel tank with screws, so that the oil pump 4 is fixed in the upper chamber of the fuel tank, which saves the peripheral space of the fuel tank and maintains the original Motorcycle body structure. Fuel pump 4 draws fuel and delivers it to the engine through fuel pipe 5 .
