Document Type and Number:
Japanese Patent JP4521234
Kind Code:
B2
Abstract:
An object of the invention is to change a layout structure of a hydraulic continuously variable transmission apparatus (HST) particularly constituting a hydromechanical continuously variable transmission apparatus (HMT) as a continuously variable transmission apparatus, thereby achieving a simplification of structures of a working vehicle and a traveling drive system, and an easiness of a maintenance. In a working vehicle provided with an HMT structured such as to combine an HST and a planetary gear mechanism as the traveling drive system so as to output and rotate a power of an engine while shifting gear, the HST is provided with a hydraulic pump and a hydraulic motor integrally in a front wall of a transmission case, and is arranged in an upper side of a transmission shaft transmitting the power to the transmission case from the engine.
