Document Type and Number:
WIPO Patent Application WO/2016/111578
Kind Code:
A1
Abstract:
According to an automatic gear shifting method for a construction machine, the traveling speed of the construction machine can be detected. An input shaft speed and an output shaft speed of a transmission of the construction machine can be synchronized according to the detected traveling speed. The transmission can be shifted. Therefore, the transmission can be automatically shifted from a low gear to a high gear according to the traveling speed of the construction machine, and vice versa, and thus the fuel efficiency of the construction machine and convenience for an operator can be improved.
