Hydrostatic continuously variable transmission

摘要

To provide a hydrostatic continuously variable transmission including a constant displacement type swash plate hydraulic pump and a variable displacement type swash plate hydraulic motor, wherein a thrust load generated between an input cylindrical shaft of the hydraulic pump and a motor swash plate anchor of the hydraulic motor is not transmitted to an output shaft of the transmission. An input cylindrical shaft and a pump cylinder are axially fixedly connected by a first angular contact bearing interposed therebetween, and a cylinder block and a motor swash plate anchor are axially fixedly connected by a second angular contact bearing interposed therebetween.
