    Abstract: A hydraulic transaxle of the present invention includes an axle, a hydraulic static transmission (“HST”), a center case that has pair of oil passages for circulating the hydraulic oil between the hydraulic pump and the hydraulic motor, and a gear mechanism that transmits an output of the HST to the axle. A case supports the axle and accommodates the HST while also forming an oil reservoir. A hydraulic motor of the HST includes a motor shaft, a cylinder block with a plurality of cylinders fixed to the motor shaft, a plurality of pistons inserted into the cylinders, a fixed swash plate abutted by the plurality of pistons, and a fixed swash plate holder that supports the fixed swash plate with respect to the case. The motor shaft of the hydraulic motor is supported by the center case and the fixed swash plate holder.

    Abstract: A shift-drum speed change mechanism includes a first drum spring biasing a first drum toward a first side in an axial direction, which is a side on which a first slider comes into contact with a first speed change member, a first fork spring biasing a first shift fork toward a second side in the axial direction, which is a side opposite to the first side in the axial direction, with a weaker biasing force than the first drum spring, and a first stopper member for the first drum, defining an end of movement of the first drum toward the first side in the axial direction.

    Abstract: A transaxle includes: an axle housing in which an input gear is rotatably supported; a differential casing that is contained in the axle housing while being rotatably supported relative to the axle housing; first and second side gears as a pair of spur gears that are contained in the differential casing, coaxially arranged, relatively rotatable with each other, and rotatable relative to the differential casing; a group of pinions as spur gears that are rotatably supported, in the differential casing, by rotational shafts that are in parallel with axes of the first and the second side gears in the differential casing, the group of pinions transmitting power between the first side gear and the second side gear; and a final gear having a ring shape that is contained in the axle housing, meshes with the input gear, incorporates the differential casing, and is relatively unrotatably coupled to the differential casing.

    Abstract: A movable structure driving unit is a movable structure driving unit used for a movable structure, including: an electric motor that is electrically connected to a power supply and that drives a front wheel; a rear-side motive power source that drives a rear wheel; a jump detector that detects a jump of the front wheel from ground; and a motor controller that controls driving of the electric motor. The motor controller stops supply of a driving current from the power supply to the electric motor when the jump of the front wheel from the ground is detected in a state in which driving of the front wheel and the rear wheel is instructed.

    Abstract: A transaxle with a brake includes an axle supported by the transaxle casing, a continuously variable transmission disposed in the transaxle casing, a braking device that is disposed in the transaxle casing and locks a rotation of the axle, a speed control arm that is journaled so as not to rotate relatively with respect to the transmission operating shaft of the transmission, controls the transmission, and is capable of changing a rotation of the axle continuously. A brake arm that is journaled with respect to an operating shaft of the braking device and a relay arm that is journaled so as to be relatively rotatable with respect to the transmission operating shaft are also included. The relay arm has one end connected to the brake arm via a link mechanism and the other end for lock operation input.

    Abstract: A transaxle may include an input shaft including a first shaft and a second shaft; and a torque limiter including an input unit and connected to the other end of the first shaft so as to be relatively non-rotatable, a driven unit connected to a second end of the second shaft so as to be relatively non-rotatable, and a region transmitting a torque between the input unit and the driven unit while limiting the torque to a predetermined value or less. By connecting the input unit and the driven unit of the torque limiter with a one-way clutch, the second shaft is rotatable relative to the first shaft when a rotation direction of the first shaft is a first direction, and the second shaft is non-rotatable relative to the first shaft when the rotation direction is a second direction opposite to the first direction.
