摘要： A hydraulic transaxle facilitates mounting a parking brake unit which requires no link mechanism and is compact. The parking brake unit includes a brake rotor provided on a rotation shaft and a locking member being displaceable between a first position where the brake rotor is locked and a second position where the brake rotor is unlocked. The locking member includes a locking portion which is engaged in a recess formed in the brake rotor that locks the brake rotor in the first position, and a non-locking portion which is placed at a position corresponding to the recess and which separates from the brake rotor in the second position. The hydraulic transaxle further includes an oil-supply mechanism capable of displacing the locking member to the second position.

摘要： A clutch system includes a transmission shaft, a gear, and a clutch slider. The gear is provided on the transmission shaft rotatably relative to the transmission shaft. The clutch slider is provided on the transmission shaft axially slidably along the transmission shaft and unrotatably relative to the transmission shaft. The gear and the clutch slider are provided with respective clutch teeth. The clutch system is set in either a clutch-on state where the clutch teeth of the gear engage with the clutch teeth of the clutch slider or a clutch-off state where the clutch teeth of the gear disengage from the clutch teeth of the clutch slider. The clutch system is provided with a hydraulic control system to hydraulically control the respective axial slide actions of the clutch slider in a clutch-on direction for realizing the clutch-on state and in a clutch-off direction for realizing the clutch-off state.

摘要： A compact transaxle is provided with a multi-speed transmission mechanism having transmission shafts extended in a longitudinal direction so that the transaxle can be combined with an engine having a crankshaft in the longitudinal direction. A bevel gear serving as an output member of the multi-speed transmission mechanism having the transmission shafts meshes with a bevel gear provided on a speed-reduction intermediate shaft extended parallel to a pair of differential yoke shafts of a differential mechanism extended in a lateral direction. A single transaxle casing incorporates the multi-speed transmission mechanism, the differential mechanism, and a speed-reduction mechanism including the speed-reduction intermediate shaft, thereby constituting the transaxle.

摘要： A transaxle includes a braking unit disposed in the transaxle casing, the braking unit configured to brake the axle. The braking unit includes an operating shaft projecting from one side of the transaxle casing. A link mechanism of the transaxle is includes a relay arm rotatably pivoted on a shaft provided on the one side of the transaxle casing, a brake arm fixed to the operating shaft, the brake arm being configured to rotate between a braking position and an unbraking position of the braking unit together with the operating shaft, a first link configured to manipulate the relay arm, and a second link configured to join the relay arm to the brake arm. The link mechanism constrains motion of the brake arm through the second link such that an external force on the braking unit cannot cause an unexpected release from the braking state.
