摘要： The electrically variable transmission family of the present invention provides low-content, low-cost electrically variable transmission mechanisms including first, second and third differential gear sets, a battery, two electric machines serving interchangeably as motors or generators, and four or five selectable torque-transfer devices (two clutches and two or three brakes). The four or five selectable torque transfer devices are engaged singly or in combinations of two to yield an EVT with a continuously variable range of speeds (including reverse) and four mechanically fixed forward speed ratios. The torque transfer devices and the first and second motor/generators are operable to provide five operating modes in the electrically variable transmission, including battery reverse mode, EVT reverse mode, reverse and forward launch modes, continuously variable transmission range mode, and fixed ratio mode.

摘要： PROBLEM TO BE SOLVED: To provide a continuously variable transmission positioned by a hydraulic control piston, comprising a driving sheave and a driven sheave respectively having adjustable pistons. SOLUTION: For suitably positioning each adjustable portion, the piston is pressurized by a control system, and a flexible driving member hung on a sheave operates with a desired diameter so that a desired gear ratio is established between a driving sheave and a driven sheave. A control device has two variable displacement pump assemblies for supplying working fluid at a desired pressure for keeping a desired ratio and generating ratio change required by an operation condition. One pump supplies a primary pressure proportional to a torque request of a CVT, and the other pump supplies a pressure required to generate the ratio change. A ratio control pump is movable to both sides of a neutral position so that a primary pump can keep a torque capacity pressure required in a system and simultaneously supply ratio control fluid to one of adjustable portions.
