摘要： 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.

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： Transaxle systems for a vehicle are disclosed where each of right and left transaxle units includes a hydraulic pump, a hydraulic motor and a casing incorporating the hydraulic pump and motor. Each hydraulic pump has a pump displacement control means operatively connected to a pump control arm pivoted on the casing, and each hydraulic motor has a motor displacement control means operatively connected to a motor control arm pivoted on the casing. A single motor controlling manipulator is operatively connected to the motor control arms to simultaneously shift the motor displacement control means of the right and left transaxle units between large displacement positions and small displacement positions.

摘要： A brake system is provided for a vehicle equipped with a continuously variable belt transmission (hereafter a “CVT”) having a CVT input shaft and a CVT output shaft. The CVT functions as a clutch-disengagement action for isolating rotation of the CVT output shaft from the CVT input shaft when a rotary speed of the CVT input shaft is reduced to a certain level. The vehicle is equipped with a prime mover driving the CVT input shaft so that an output rotary speed of the prime mover defines the rotary speed of the CVT input shaft. The vehicle includes an accelerator manipulator for controlling the output rotary speed of the prime mover. The brake system can cause a resistance against the rotation of the CVT output shaft using the accelerator manipulator to reduce the output rotary speed of the prime mover to make the CVT function as the clutch-disengagement action.

摘要： A transaxle comprises a transaxle casing, axle, brake, brake arm, first and second link members, and relay arm. The brake includes a brake operation shaft pivotally supported by the transaxle casing for shifting between brake activation and inactivation states. A starting end of the first link member is connected to a manipulator, and a terminal end of the second link member is connected to the brake arm. The relay arm is pivotally centered on a first pivotal axis outside of the transaxle casing, and includes a first arm portion extended from the first pivotal axis to a first end and a second arm portion extended from the first pivotal axis to a second end. A terminal end of the first link member is connected to the first arm portion, and a starting end of the second link member is connected to the second arm portion.

摘要： A transaxle includes a continuously variable transmission including a speed control arm and a neutral return spring allowing a biasing force to act on the speed control arm toward a neutral position, the speed control arm configured to operate from the neutral position to a forward position or a backward position to perform a continuous speed variation. The biasing force does not act on the speed control arm when the neutral return spring ranges from the neutral position to a predetermined speed position on a forward movement side, and the biasing force acts on the speed control arm when the neutral return spring ranges from the predetermined speed position to a maximum speed position on the forward movement side.
