Title:
OFF-HIGHWAY CONTINUOUSLY VARIABLE PLANETARY-BASED MULTIMORE TRANSMISSION INCLUDING INFINITE VARIABLE TRANSMISSION AND DIRECT CONTINUOUSLY VARIABLE TRANMISSION
Document Type and Number:
WIPO Patent Application WO/2015/195759
Kind Code:
A3
Abstract:
A variable transmission includes various powerpath layouts comprising configurations based on a two stage gearbox with a first stage providing a multi-mode configuration combining power-split modes, direct drive modes and a directional stage to select driving either forward or reverse with a pair of direction clutches; or multi-mode operation comprising a planetary gear set as the central part of the configurations together with the CVP, wherein the modes are selected by engaging a clutch/brake while releasing the others. These configurations are particularly useful for compact Off-Highway applications such as compact wheel loaders having a wide speed range and high rimpull force requirement where an operator may also desire limited jerking motion during shifts in the low speed range.
