Title:
A DUAL-MODE ELECTROMECHANICAL STEPLESS GEAR AND THE METHOD FOR MAKING AND OPERATING THE SAME
Document Type and Number:
WIPO Patent Application WO/2009/079917
Kind Code:
A1
Abstract:
A dual-mode electromechanical stepless gear, which includes: an input shaft (Input), an output shaft (Output), one planetary gear system which has at least three coaxial rotating parts, two motors (EM1,EM2), an motor controller (CTL) and an clutch (CL1,CL2,CL3). The said planetary gear system has at least three branches; each branch corresponds to one coaxial rotating part. The first branch is connected to the first motor in the way of constant change gear ratio; the second branch is connected to the input shaft in the way of constant change gear ratio; the third branch is connected to the output shaft system in the way of constant change gear ratio; the second motor is connected selectively to the two branches except for the first branch, wherein one branch is connected to the output shaft system. The stepless gear has at least two power diffluence modes which includes output power diffluence mode. The different working mode overlays different change gear ration region. The stepless gear provides also at least a constant output/input ratio change gear ratio.
