no. 1 Embodiment approach
[0029] figure 1 It is a side view showing the towing vehicle 10 of this embodiment. In this specification, the front of the tractor vehicle 10 is referred to as the Y direction. Let the right direction of the tractor vehicle 10 be the X direction. Let the upper side of the tractor vehicle 10 be the Z direction. exist figure 1 In , the X direction, the Y direction, and the Z direction are shown. exist image 3 The X direction, Y direction, Z direction shown in the figure 1 The X-direction, Y-direction, and Z-direction shown in are the same.
[0030] The tractor truck 10 is a vehicle loaded with cargo to be transported and transported. The tractor vehicle 10 includes a tractor head 11 and a trailer 12 .
[0031] The tractor head 11 is connected to the trailer 12 and tows the trailer 12 . The tractor head 11 uses hydrogen to travel. More specifically, the tractor head 11 is driven by supplying hydrogen gas from the tank 32 included in the tractor head 11 and the tank 25...
Embodiment approach 1
[0075] In the above embodiments, the fuel is hydrogen. However, the fuel may be, for example, other hydrocarbons such as methane, ethane, and natural gas. When the fuel is used as the fuel gas of the fuel cell, it is preferable that the tractor vehicle is provided with a reformer for reforming hydrocarbons to generate hydrogen. In addition, instead of the fuel cell, an internal combustion engine or an external combustion engine that burns fuel gas to obtain kinetic energy may be provided on the tractor head.
[0076] In the above embodiment, the tanks 25 and 32 can store hydrogen gas at a maximum pressure of 70 MPa. However, the tank for storing high-pressure gas may also be in the form of storing liquefied gas instead of compressed gas. In this manual, "high-pressure gas" refers to high-pressure gas specified in Article 2 of the High-pressure Gas Safety Act (Showa 26 Law No. 204, April 1, 2013 Enforcement Law). That is, in this specification, "high-pressure gas" belongs to...
Embodiment approach 2
[0084] In the above embodiment, the first piping P21 is made of stainless steel (refer to figure 2 ). However, the first piping P21 may also be made of other materials. In addition, the first piping P21 may have a structure having a plurality of layers.
[0085] In the above-mentioned embodiment, the portion connecting the decompression portion 27 and the outlet-side connection portion P22o in the second pipe P22 is made of rubber. However, the second pipe P22 may be made of other materials such as resin. In addition, the second piping P22 may have a structure having a plurality of layers. However, it is preferable that the second piping P22 has a lower rigidity than the first piping P21. It is preferable that the second pipe P22 has a structure that is more easily elastically deformed than the first pipe P21.
[0086] In the above-described embodiment, the portion connecting the decompression portion 27 and the outlet-side connection portion P22o in the second piping P2...
