A hybrid vehicle includes an engine that drives first wheel, and a motor that drives second wheel. The hybrid vehicle includes (1) a minute speed launch support mode where the hybrid vehicle is driven only by the motor as a drive source, (2) a sudden launch support mode where the hybrid vehicle is driven by the engine and motor as the drive source, and (3) a smooth launch support mode where the hybrid vehicle is driven only by the motor as the drive source in an early stage, is driven by the engine and motor in a middle stage, and is driven only by the engine in a late stage, and if an operation amount of an acceleration instruction unit is not 0 or is substantially not 0, any one of the support modes is executed according to an operation status of the acceleration instruction unit.

To provide a vehicle body structure for an autonomously traveling vehicle that is distinguished for maintainability.

A vehicle body structure (1) for an autonomously traveling vehicle that travels on wheels (3) provided on a chassis (2) includes side frames (4R), (4L) that extend in a chassis longitudinal direction on both sides of the chassis with respect to a chassis width direction, first drive units (20) in each of which a drive motor (5) that is for driving the wheel (3), a reduction gear (6), and a drive shaft (7) that drives the wheel (3) are integrally configured, and second drive units (30) which each rotatably hold a drive shaft (7) that drives the wheel (3). The vehicle body structure (1) is characterized in that the first drive units (20) and the second drive units (30) are each provided so as to be integrally mountable in and dismountable from the same side frames.

A work vehicle including: a transmission unit that is provided with, on a shaft that is provided in a power transmission path leading from an input shaft to a power transmission shaft but is not a speed change shaft, a gear member that has an engagement recess, and a claw member having an engaging claw that engages with the engagement recess and to which rotational power is transmitted. There are gaps in a rotational direction between the engaging claw and both ends, in the rotational direction, of the engagement recess.

Disclosed is a wheeled vehicle. The wheeled vehicle includes various features for operation by a rider, such as a throttle actuation assembly and various components for operation and manipulation of the vehicle.

An electric vehicle (1) includes, a chassis (10), a pair of front (21, 31) and rear wheels (22, 32) provided on a right side of the chassis (10) and a pair of front (21, 31) and rear wheels (22, 32) provided on a left side of the chassis (10), two motors (41R, 41L) that drive any of the right and left front wheels (21, 31) or the right and left rear wheels (22, 32), a sprocket (21b, 22b, 31b, 32b) and a belt (23, 33) serving as a power transmission member transmitting power between the front and rear wheels of each pair, and a battery (40) that supplies power to the electric motors (41R, 41L). Changing of a direction or turning of the electric vehicle (1) is performed by changing the rotational speed or a rotation direction by gearboxes (43R, 43L) for the power from the electric motors (41R, 41L).

A transfer case includes primary and secondary output shafts, along with a secondary torque transfer mechanism and a locking mechanism, which are configured to selectively couple the primary and secondary output shafts. The secondary torque transfer mechanism comprises a sprocket coupled to the secondary output shaft, and a plate clutch coupled to the sprocket to selectively form a friction coupling with the primary output shaft. The locking mechanism selectively couples the primary output shaft to the sprocket, and includes a locking sleeve and an actuator that moves the locking sleeve between a first position and a second position. In the first position, the locking sleeve forms a first splined connection with the primary output shaft and forms a second splined connection with the sprocket. In the second position, the locking sleeve forms the first splined connection with the primary output shaft and forms a second splined connection with the sprocket.

A drive system driving front wheels and rear wheels of a vehicle includes a powertrain comprising an output shaft, a rear driveshaft coupled to the rear wheels, a drive mechanism coupling the output shaft to the rear wheels, a front driveshaft shaft coupled to the front wheels and a prop shaft coupling the rear driveshaft and to the front driveshaft.

A drive device for all-wheel-drive motor vehicles, includes a primary axle driven by a drive unit via an axle differential and a secondary axle driven via the left and right output elements of the axle differential and via transmitting means. The transmitting means are formed by at least two switching elements, which are arranged coaxial to the axle differential of the primary axle and which act on the left and right drive shaft of the secondary axle via belt or chain transmissions.

A motorized wheelbarrow including a motor and a drive pulley that rotates when the motor is operating. The motorized wheelbarrow also includes wheels and a drive train assembly for transmitting power from the motor to the wheels. The motorized wheelbarrow also includes a clutch assembly movable between a connected condition, in which the motor and the drive train assembly are connected by the clutch assembly, and a disconnected condition, in which the motor and the drive train assembly are not connected with each other, and a brake assembly movable between an engaged condition, in which the brake assembly resists rotation of the wheels, and a disengaged condition, in which the brake assembly does not resist rotation of the wheels. Both of the clutch assembly and the brake assembly are controlled by a single control assembly so that the clutch assembly and the brake assembly are mutually functionally exclusive.
