Description

Heavy-duty vehicle liquefied natural gas component installation structure

field of invention

The utility model relates to a heavy-duty vehicle liquefied natural gas component, in particular to a heavy-duty vehicle liquefied natural gas component installation structure.

Background technique

Heavy-duty vehicle liquefied natural gas components (referred to as LNG components) usually include gas cylinders and gas supply control systems. In order to utilize the space of the vehicle as much as possible, the LNG assembly is usually installed on one side of the bottom of the vehicle frame in the prior art heavy vehicles. Although the installation structure of the LNG components of heavy vehicles in the prior art is short in the LNG pipeline, the gas supply pipeline after gasification is relatively long, making it difficult to ensure the air pressure required by the engine for the gasified natural gas. In addition, since the gas cylinder and the gas supply control system both need to occupy a large space, the existing heavy-duty vehicles install the gas cylinder and the gas supply control system on one side of the bottom of the frame, making it difficult for the LNG components to ensure the ground clearance , Seriously affect the passing performance of heavy vehicles. Obviously, the installation structure of the LNG components of the heavy-duty vehicles in the prior art has problems such as difficulty in ensuring the air pressure required by the engine and the ground clearance.

Contents of the invention

In order to overcome the problems existing in the installation structure of heavy-duty vehicle LNG components that it is difficult to ensure the air pressure required by the engine and the ground clearance, the utility model proposes a heavy-duty vehicle LNG component installation structure. The utility model heavy-duty vehicle liquefied natural gas component installation structure includes gas cylinders, liquid pipelines, gas supply control systems and gas pipelines, the gas cylinders are installed on one side of the bottom of the frame, and the gas supply control system is installed on the bottom of the frame. On the other side, the liquid pipeline is used to connect the gas cylinder and the gas supply control system, and the gas pipeline is used to connect the gas supply control system and the engine.

The beneficial technical effect of the installation structure of the heavy-duty vehicle liquefied natural gas components is to make full use of the space at the bottom of the vehicle frame, shorten the air supply pipeline from the air supply control system to the engine, ensure the air pressure required by the engine, ensure the ground clearance of the vehicle, and ensure Vehicle safety and passability.

Accompanying drawing 1 is the schematic diagram of the installation structure of the heavy-duty vehicle liquefied natural gas component of the utility model.

The installation structure of the heavy-duty vehicle liquefied natural gas components of the utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

Accompanying drawing 1 is the schematic diagram of the installation structure of the liquefied natural gas components of the utility model, in which, 1 is a gas cylinder, 2 is an air supply control system, 3 is a liquid pipeline, 4 is a gas pipeline, 5 is an engine, and 6 is a Air filter, 7 is the speed changer, and 8 is the storage battery. As can be seen from the figure, the utility model heavy-duty vehicle liquefied natural gas component installation structure includes a gas cylinder 1, a liquid pipeline 3, a gas supply control system 2 and a gas pipeline 4. The gas cylinder 1 is installed on one side of the bottom of the vehicle frame, and the supply The air control system 2 is installed on the other side of the bottom of the vehicle frame, the liquid pipeline 3 is used to connect the gas cylinder 1 and the air supply control system 2, and the gas pipeline 4 is used to connect the air supply control system 2 and the engine 5 . Apparently, the utility model heavy-duty vehicle liquefied natural gas component installation structure makes full use of the space at the bottom of the vehicle frame, and there is still enough space to assemble the chassis and other assembly parts on the top after the gas cylinder is assembled, and maintain the vehicle frame as much as possible. The original structure of the bottom and the installation position of parts remain unchanged. In addition, since the gas cylinder and the air supply control system are respectively assembled on both sides of the frame, the requirement for space on one side of the frame is effectively reduced, and the ground clearance at the bottom of the vehicle can be effectively improved; at the same time, a shorter wheelbase can be used The frame of the vehicle is equipped with a larger volume of gas cylinders to achieve a longer cruising range, reduce the number of times users add LNG, increase the utilization rate of the vehicle, and strive for greater economic benefits for users.

Obviously, the beneficial technical effect of the installation structure of the heavy-duty vehicle liquefied natural gas components of the utility model is to make full use of the space at the bottom of the vehicle frame, shorten the air supply pipeline from the air supply control system to the engine, ensure the air pressure required by the engine, and ensure the ground clearance of the vehicle , to ensure the safety and passability of vehicles.
