Abstract:
A transmission mechanism for a vehicle having a power transmission path for transmitting power from a drive source installed in a vehicle body through an HST disposed away from the drive source toward a first direction longitudinally of the vehicle body at least to a differential gear unit for driving axles toward the first direction, the transmission mechanism being characterized in that:a transmission is provided between the HST and the differential unit, the transmission having a casing, an input shaft connected to a drive shaft of the drive source by a shaft, and a first output shaft coupled to the differential gear unit, the input shaft extending from the casing toward a second direction opposite to the first direction, the HST comprising a hydraulic pump having, a pump shaft extending into the transmission casing, and a hydraulic motor cooperative with the hydraulic pump and having a motor shaft extending into the transmission casing, the casing of the transmission being connected as a unit with both a casing of the HST and a casing of the differential gear unit, the casing of the HST facing immediately the drive source, the transmission comprising as housed in the transmission casing a mechanical cooperating mechanism coupling the input shaft to the pump shaft and coupling the motor shaft to the output shaft to provide the power transmission path.
