Abstract

The invention discloses a hydraulic hybrid power concrete mixing carrier control system and belongs to the technical field of hydraulic pressure. The hydraulic hybrid concrete mixing carrier control system comprises an upper vehicle mixing system, a lower vehicle running system and a hydraulic regeneration control system, wherein the hydraulic regeneration control system comprises an upper vehicle mixing regeneration control system and a lower vehicle running regeneration control system. According to the invention, recovery and utilization of residual power of an upper vehicle engine and recovery and utilization of finished automobile braking energy of a lower vehicle are implemented, and automobile power matching is implemented; a unique serial pump structure unit is adopted to realize upper vehicle power matching and system control and meanwhile, pressure impact in the mixing operation process is balanced; and due to adoption of a bus control technology, a finished vehicle is safe and reliable and is easy to realize.

Description

technical field [0001] The invention relates to a control system of a concrete mixer truck, in particular to a control system of a hydraulic hybrid concrete mixer truck. Background technique [0002] Construction machinery products are widely used in the construction of buildings, mines, ports and other municipal projects. However, the development of construction machinery is facing the problems of high energy consumption and serious pollution. Therefore, it is of great social and economic significance to carry out energy-saving technology research. [0003] The hydraulic hybrid technology is based on the principle of secondary regulation, and utilizes the characteristics of the core component hydraulic pump / motor that can work in four quadrants to realize the recovery and utilization of the energy lost by construction machinery vehicles, thereby achieving the effect of energy saving and emission reduction. The hydraulic hybrid system has the characteristics of high power de...
