The invention relates to a heavy-duty trailer (10) in which at least one of the wheels (12) has a MacPherson independent wheel suspension (16). The wheel (12) can be a steered wheel, wherein the steering cylinders (94) of the steering device (40) enclose an angle (a) with the longitudinal direction (L) of the trailer. The transverse control arms (30l, 30r) can also be articulated onto the trailer frame at least in the longitudinal center plane (E) of the trailer (10).

The present invention relates to a motor wheel for a vehicle and a vehicle comprising the motor wheel. The motor wheel comprises a wheel, an electric motor, a reduction gear transmitting rotation from the electric motor to the wheel, and a dampening structure connecting the wheel to a vehicle bearing member. The electric motor comprises an electric motor case. The reduction gear comprises a reduction gear case coupled to the electric motor case and rotatably mounted within the wheel hub. The electric motor case is connected to the bearing member of the vehicle and is displaceable relative to the bearing member. The invention improves dynamic properties to the vehicle, reduces vibrations transmitted to the vehicle body, and provides a more comfortable drive.

Provided are a transportation device for transporting heavy plate-shaped cargoes such as thick plate products, and a transportation system using the transportation device. The transportation device may include: a device body unit; a device moving unit provided on the device body unit to move the transportation device; and a cargo loading unit provided on the device body unit for self-loading cargo. The transportation device is capable of rapidly loading and transporting plate-shaped heavy objects such as thick plate products of an iron mill without using additional lifting/unloading apparatuses and heavy pallets (cassettes) for markedly decreasing the total transportation (distribution) time necessary for lifting, transportation, and unloading of cargo, providing efficient transportation environments, improving productivity, and decreasing costs.

An axle suspension has an axle support mounted in a swivel so as to rotate about an axis of rotation and a steering lever that is connected with the axle support in torque-proof manner and can be pivoted about the axis of rotation. The axle support accommodates at least one wheel axle and is mounted so as to be displaceable relative to the axis of rotation, in the wheel axle direction, on an adjustment path.

A biaxially extensible and retractable wheel-leg mechanism for a vehicle includes a pantograph coupling limb assembly with a plurality of coupling limbs which are coupled together in an articulated manner. A wheel hub motor and a steering actuator operatively connected thereto are arranged on a first coupling limb, and the wheel hub motor is designed to rotate a vehicle wheel drivingly connected to the wheel hub motor. The steering actuator is designed to set a steering angle of the wheel of the vehicle. The wheel-leg mechanism additionally comprises a rotary drive for positioning the coupling limb, said rotary drive being drivingly arranged on a first joint between a second coupling limb and a third coupling limb. The rotary drive is designed to set a relative angular position between the coupling limbs coupled together in an articulated manner such that the position of the wheel hub motor relative to the rotary drive can be adjusted in the longitudinal direction and/or in the vertical direction of the vehicle.

A heavy-duty active suspension, including a suspension frame, a lifting unit, a pin axle, a through axle, two wheel-driving units, an encoder, and a displacement sensor. The lifting unit is mounted on an upper side of the suspension frame for driving a heavy-duty support platform to rise and descend. The pin axle is mounted across the suspension frame along a front-rear direction. The through axle is rotatably mounted on the pin axle through a bearing, and is across the suspension frame along a left-right direction. The two wheel-driving units are respectively mounted on both ends of the through axle. The encoder is installed on the through axle for measuring a swing angle of the through axle. The displacement sensor is installed between an output end of the lifting unit and the suspension frame. A suspension vehicle including the active suspension and a leveling control method thereof are further provided.

A wheel module is disclosed. The wheel module according to the present embodiment includes a knuckle configured to rotatably support a wheel, a steering device including an actuator configured to rotate the knuckle and steer the wheel, and a reinforcing structure provided between the knuckle and a vehicle body, wherein an output shaft of the actuator is disposed parallel to a vertical direction, the reinforcing structure includes a first end rotatably connected to the knuckle along a first axis parallel to the vertical direction and a second end connected to the vehicle body, and a rotation axis of the output shaft and the first axis are coaxially provided.

Disclosed is a corner module apparatus for a vehicle. The corner module includes a knuckle coupled to a wheel bearing rotatably supporting a wheel, a drive motor, configured to generate a drive power, spaced a distance away from the wheel, a transfer shaft, disposed between the wheel and the drive motor, configured to transfer the drive power generated from the drive motor, a suspension connected to the knuckle and configured to absorb shock transferred from a road surface, and a steering system configured to support the drive motor and the suspension and to adjust a steering wheel of the wheel.
