Problems solved by technology

The hydraulic valve block needs to be controlled by the control system, but in the early stage of design and development, the control system is not perfect, but the earlier the test and development time of the hybrid electric vehicle is, the better. Therefore, the development of the control system of the hydraulic valve block and the hybrid There are contradictions between the tests, which restrict the development of hybrid tests

Abstract

The invention relates to the technical field of hybrid electric vehicle research and development and discloses a hybrid electric vehicle test tool. The hybrid electric vehicle test tool comprises an external oil tank, a pressure oil pump and a lubrication cooling oil pump. An oil absorption chamber is arranged in the external oil tank. The pressure oil pump and the suction cooling oil pump communicate with the oil suction chamber through oil suction pipes correspondingly. The pressure oil pump communicates with a pressure oil cavity of a clutch of a hybrid electric vehicle through a first oiloutlet pipe. The lubrication cooling oil pump communicates with a lubricating oil channel of the clutch of the hybrid electric vehicle through a second oil outlet pipe. The hybrid electric vehicle test tool can guarantee normal operation of the clutch without control software, so that relevant tests of the hybrid electric vehicle are carried out normally, it is guaranteed that the tests can be carried out effectively at earlier stage of design, research and development, and the development efficiency and quality of the hybrid electric vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of research and development of hybrid electric vehicles, in particular to a hybrid electric vehicle test tool. Background technique [0002] A hybrid vehicle requires the coupling of the engine and the motor, and realizes various functions such as pure electric drive, electric auxiliary drive, and motor starting the engine, so the clutch is basically used, and various functions are realized by controlling the opening and closing of the clutch. The opening and closing of the clutch is controlled by controlling the pressure of the oil, and at the same time, the clutch needs continuous and sufficient lubrication and cooling. Specifically, the oil pump absorbs oil from the oil pan, and then establishes oil pressure through the hydraulic valve block, and is divided into two circuits, one oil pressure controls the opening and closing of the clutch, and the other oil pressure supplies the lubrication and cooling of...
