Description
Technical Field
The invention relates to an engineering vehicle for short-distance material transportation, in particular to a transportation dump truck driven by a hydraulic device.
Background
A dump truck is a special short-distance material conveying vehicle with a tiltable hopper. A bucket-shaped container is arranged on the vehicle body and can be overturned to facilitate unloading. The method is widely applied to construction sites, road and bridge engineering, mine salt farms, wharf pastures and the like. The classification according to the structure generally includes single-axle dump trucks, double-axle dump trucks, flat-end dump trucks, tip dump trucks, double-axle semi-trailer dump trucks and the like.
In the prior art, an engine is generally connected with a gearbox of a dump truck, power is directly output to front wheels and rear wheels through a coupler to drive the front wheels and the rear wheels, and the running direction of the dump truck is changed in a conventional front wheel steering mode. In general, a dump truck adopting the driving structure and the steering method is provided with a hopper at the rear of the vehicle to ensure the stability of the vehicle and the steering accuracy. The engine is adopted to carry out mechanical transmission through a gearbox, a coupler and the like, the clutch is required to be matched with gear shifting, the gear shifting controllability is poor, the engine is easy to flameout, and the engine is difficult to adapt to a complex road surface of a construction site. Moreover, although the existing large-tonnage dump truck is provided with a hydraulic torque converter to improve the maneuverability of the truck, the arrangement mode has low efficiency and serious energy waste, and most importantly, an engine below 30kW does not have a matched hydraulic torque converter.
Meanwhile, although the steering mode adopting the front wheels as the steering wheels is the conventional steering mode of the existing dump truck, the steering mode has poor stability, and the trafficability is not optimistic when the dump truck faces a complex road surface. Moreover, over many years of use, the driver's in-person experience is: after the dump truck is loaded with goods, a certain angular deviation occurs in the steering of the vehicle during driving due to the rearward movement of the center of the vehicle. Dump trucks with rear wheels as steered wheels are also available on the market, but such dump trucks have a rear centre of gravity when loaded with goods and a rear wheel angle deflection during steering, which reduces the stability of the vehicle. Some dump trucks also adopt a 'bowing' steering mode, and the common adoption is that two hydraulic cylinders are matched with a hinge mechanism, and the purpose of steering is realized through the stretching of the hydraulic cylinders, but the steering setting mode is relatively rigid, and due to the arrangement of the two hydraulic cylinders, the adaptability of the truck to uneven road surfaces is poor.
Therefore, a hydraulic circuit dump truck with good maneuverability, stable steering, strong road surface adaptability and maximum power limitation is needed.

The working principle of the invention is as follows: the invention discloses a dump truck driven by a hydraulic circuit. The engine is connected with an electrically controlled variable plunger pump (hydraulic pump) to convert and transmit the work of the engine. A driver operates the steering wheel, the gear lever and other operation equipment, and the action signals are transmitted to the corresponding hydraulic driving parts in real time by matching with the control console and the hydraulic controller. When an advancing or retreating instruction is given, the hydraulic controller controls the hydraulic pump to transmit power to the traveling motor, so that the traveling motor can rotate forwards and backwards according to the instruction, and the steering of the vehicle is realized. When the vehicle is driven to turn, the hydraulic controller controls the hydraulic pump to output power to the steering hydraulic cylinder to force the hydraulic rod to extend or retract so as to realize the steering of the vehicle. When a hopper rotation instruction is given, the hydraulic controller controls the corresponding rotating device to push the hopper rotating mechanism, so that the rotation of the hopper is realized. When goods need to be loaded and unloaded, the lifting hydraulic cylinder of the hopper is controlled by the hydraulic controller to realize the lifting and falling of the hopper.
When a vehicle runs, the hydraulic joint linkage steering engine realizes the proper swing of the vehicle through the matching and linkage of the pin shaft, the pull plate, the hinge shaft and the radial spherical plain bearing so as to adapt to the gravity center change of the vehicle caused by the fluctuation change of a road complex road surface and ensure the stability of the vehicle. Meanwhile, the steering of the vehicle is realized through the matching of the hinge shaft and the steering hydraulic cylinder.
