Description

Technical Field

[0001] The utility model relates to the field of dump trucks, in particular to a chassis of a dump truck with a gas engine. Background Technique

[0002] Gas engines, especially engines fueled by natural gas, have several remarkable advantages. First of all, the price of natural gas is usually much lower than that of gasoline and diesel, which gives gas engines a significant advantage in operating costs. The main component of natural gas is methane, and its sulfur content is low. Compared with other fossil fuels, natural gas produces the least amount of pollutants during the entire life cycle of extraction, production, storage, transportation, and use. Therefore, it is called a "clean fuel". Therefore, gas engines have broad application prospects in dump trucks.

[0003] The gas supply system of a gas engine includes a gas cylinder, a vaporizer, a pressure reducer, an injector, etc. To facilitate the layout of the space of the dump truck chassis, the gas cylinder is often arranged at the front of the frame, and the gas engine is arranged at the rear of the frame. To facilitate gas supply and water supply, a hose is generally used to connect the vaporizer and the engine, and a strap is used to fix the intake hose and the water supply hose to the frame.

[0004] In the above technical solution, since the gas supply system of the gas engine of the dump truck is far from the engine, the intake and water supply hoses are relatively long. On the one hand, it is easy to rub and collide with the wire harness and brake pipe bundle inside the frame, affecting each other; on the other hand, if the strap is fixed too tightly, it is easy to cause the outer wall of the intake hose to be pressed, reducing the gas flow rate and affecting the working efficiency of the gas engine.
