Title:
LOADER THREE-STAGE HYDRAULIC MECHANICAL STEPLESS TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/195993
Kind Code:
A1
Abstract:
Provided is a loader three-stage hydraulic mechanical combined stepless transmission device, which uses a combination of a hydraulic speed regulation loop and a mechanical loop, wherein a hydraulic circuit only transmits part of the power, thus achieving high transmission efficiency and stepless speed regulation, and greatly increasing the transmission efficiency of the transmission device such that an engine normally works in an economic rotational speed range, and the fuel consumption and noise level of the loader are reduced.
