Hydraulic transaxle and vehicle comprising it

摘要

A hydraulic transaxle including: a variable displacement hydraulic motor with a movable swash plate whose tilt angle defines a displacement of the hydraulic motor; a casing incorporating the hydraulic motor; and a mechanism for determining a range of the tilt angle of the swash plate, wherein the mechanism can fix the tilt angle of the swash plate so as to set the hydraulic motor in a fixed displacement type. A vehicle includes the transaxles for driving respective axles wherein each of the transaxles can select whether the displacement of its hydraulic motor is variable or fixed.
