Abstract

The invention discloses an engineering vehicle. A gas power device is connected to a hydraulic pump to provide an energy source for a hydraulic executing device. The engineering vehicle is simple in structure, high in torque, high in rotating speed, high in transfer efficiency and environmental-friendly. An emission is gas at a reduced pressure, so that the engineering vehicle is low in working noise and free of tail gas pollution. A standby state is extremely low in energy consumption. The gas power device used by the engineering vehicle comprises an outer ring and a core body. An at least one-step secondary flushing runner is arranged between a nozzle and an outlet of an outer ring surface of a core body. Gas enters from a gas inlet and is sprayed from the nozzle of the core body and steps of the secondary flushing runner to be acted to at least two driving concave parts on the circumference of an outer ring, thereby driving the driving concave parts to generate a thrust to push theouter ring to act rotatably so as to output power. Finally, gas is discharged by an exhausting channel through the outlet of the core body.

Description

technical field

[0001] The invention discloses an engineering vehicle, which belongs to the technical field of vehicles according to the International Patent Classification (IPC). Background technique

[0002] Engineering vehicles are vehicles that need to be used during engineering construction operations. They generally have a traveling device and a hydraulic actuator, both of which share an engine to provide driving power and hydraulic power.

[0003] However, after the running gear is shut down, in order to drive the hydraulic actuator, the engine must also be in a standby state or a low-speed working state. The working conditions are unreasonable, and a large amount of exhaust gas is easily generated, and the energy utilization rate is low.

[0004] At the same time, the harmful gases and particulate pollutants in the engine exhaust, such as CO, hydrocarbons, nitrogen oxides and other harmful gases, will seriously affect human health. Among them, the combination of CO a...
