The invention discloses a chassis of an engineering vehicle comprising a rear chassis, a hinge point, a front chassis, ttires, an oil pump, an engine, a steering cylinder, a steering gear, a priorityvalve, an appliance valve block, a connecting hydraulic cylinder, a fuel tank and a parking cylinder. According to the chassis of engineering vehicles, by installing a parking cylinder at the bottom end face of the rear chassis, a reversing solenoid valve is moved to the left, a line inlet oil enter that second hydraulic cylinder from the second one-way valve at the right end through a reversing solenoid valve; at that left end of the second hydraulic cylinder, the internal hydraulic oil is discharged through a one-way valve pipe; as that second hydraulic cylinder push the outer support framedown to the left to lift the rear chassis. The problem that the single function of the chassis in use is often not convenient for the slope parking, and bricks and the like are often need to be placedon the rear end of the tire on the slope pavement, and time-consuming and labor-consuming problems are solved in the use process. The second hydraulic cylinder pushes the outer support frame down tolift the rear chassis.
Description
technical field [0001] The invention relates to the technical field of engineering vehicle chassis, in particular to an engineering vehicle chassis. Background technique [0002] The weight of the engineering vehicle is heavy, and it is easy to cause the car to slip after parking on a large slope. When parking, it is often necessary to place bricks and other stones on the rear end of the tire on the slope road. Parking is inconvenient. With the rapid development of science and technology , Engineering vehicle chassis The engineering vehicle chassis has also been technically improved, but the single functionality of the chassis in the use of the existing technology is often inconvenient for parking on slopes. On slope roads, it is often necessary to place bricks and other stones at the rear end of the tires, which is time-consuming during use. strenuous. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is t...
