Abstract

The invention discloses an oil supply system for a split-parallel large-flow hydraulic pump group. The driving wheel 3-0 is connected to the output shaft of the power unit 1 through a spline, and its N driven wheels 3-1 to 3-N are connected to the drive shaft of the hydraulic pump 4-1 to 4-M through a spline; The two ends of the transfer case gear are respectively limited on the housing of the transfer case by bearings 7; the hydraulic pumps 4-1 to 4-M are used to pump the hydraulic oil to the subsequent hydraulic system, wherein M greater than or equal to N. The present invention aims at the large-flow hydraulic system. With the help of the gear transfer case, a single set of high-power power unit is selected to drive multiple sets of small-displacement hydraulic pumps combined in parallel, so as to realize the system oil supply in one drive and multiple forms, which can meet the needs of large-flow hydraulic pumps. The oil supply demand of the system can greatly reduce the weight and volume of the oil supply system.

Description

technical field [0001] The invention relates to the technical field of hydraulic transmission in mechanical engineering, in particular to a split-parallel large-flow hydraulic pump group oil supply system. Background technique [0002] In the hydraulic transmission system, the oil supply system drives the hydraulic pump to absorb oil from the oil source through the power unit, and then pumps the high-pressure oil to the subsequent hydraulic system. The weight and volume of the oil supply equipment usually account for a large proportion of the entire system. Lightweight design is of great significance to the entire hydraulic system. [0003] According to the current industrial design level, the higher the power of power devices such as electric motors and engines, the easier it is to achieve a higher power / weight ratio. For hydraulic pumps such as axial piston pumps, the displacement is smaller under the same pressure. Then the flow / weight ratio is easier to make higher. Th...
