Title:
MULTIFUNCTIONAL TEST BENCH FOR POWER SPLIT HYDRAULIC MECHANICAL COMPOSITE TRANSMISSION SYSTEM, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/026946
Kind Code:
A1
Abstract:
A multifunctional test bench for a power split hydraulic mechanical composite transmission system, comprising a platform (19) and a control system. An alternating current servomotor (1), a flow splitting mechanism (2), a hydraulic transmission unit (3) to be tested, a flow combination mechanism (4), and a hydraulic loading system (5) are provided on the platform (19); the control system comprises an industrial control computer (33), a PLC (32), an input end PLC D/A module (31), an output end PLC D/A module (39), a signal acquisition unit (36), a pressure sensor (42), a flow sensor (41), a speed regulation controller (38), a loading system controller (40), and a servomotor controller (30). Performance test of a hydraulic mechanical composite transmission system can be simply and reliably carried out, test time and costs can be greatly reduced, and performance test of the hydraulic transmission unit (3) to be tested, the ratio test of mechanical and hydraulic power flows, and the stage switching stability test are implemented.
