Problems solved by technology
[0005] Foreign countries have done a lot of work on basic research and applied research related to boom-type concrete pump trucks. Domestic universities have conducted research on the hydraulic system, electrical control system, intelligent pouring, and hydraulic impact of boom-type concrete pump trucks. According to research, manufacturers of boom-type concrete pump trucks continue to introduce new products, which have greatly improved the pumping hydraulic system, reversing valve, electrical control technology, conveying height and conveying distance, but no hybrid system has been seen on the boom. Application on rack concrete pump truck

The invention discloses a parallel-type oil-electric hybrid power boom type concrete pump truck. The parallel-type oil-electric hybrid power boom type concrete pump truck comprises a truck chassis unit and a pumping unit, wherein the truck chassis unit comprises a clutch, a gearbox, a transfer case, a universal transmission device, a drive axle, a running system and a braking system; and the pumping unit comprises a pumping system, a swing system, a stirring / cooling / lubricating / cleaning system and a boom / supporting leg / rotating system, and a pumping system hydraulic pump, a swing system hydraulic pump, a stirring / cooling / lubricating / cleaning system hydraulic pump, and a boom / supporting leg / rotating system hydraulic pump are correspondingly arranged on the pumping system, the swing system, the stirring / cooling / lubricating / cleaning system and the boom / supporting leg / rotating system. According to the parallel-type oil-electric hybrid power arm bracket-type concrete pump truck, a dieselengine and a motor / generator are connected in parallel through a power coupling device to form a parallel hybrid driving structure, and the energy conservation and emission reduction of the boom typeconcrete pump truck are realized through the action of an energy management system.
Description
technical field [0001] The invention relates to a parallel oil-electric hybrid arm-type concrete pump truck, which belongs to the technical field of concrete pumping machinery. Background technique [0002] Energy is the material basis for human survival and all production activities. With the rapid development of industrial technology in the world, the problems of energy shortage and environmental pollution are becoming more and more serious. At present, various countries have issued policies and regulations one after another, mandating the emission targets of motor vehicles, and prohibiting the sale and use of motor vehicles with excessive emissions. In particular, the United States and the European Union have clearly stipulated the emission standards for off-road motorized equipment, and this standard is gradually approaching the emission standards for road motorized equipment. On the other hand, some countries such as Japan give very favorable policies to the productio...
