A crawler drive unit relating to one aspect of the present disclosure includes a speed reduction mechanism provided in a running unit for causing a vehicle body to run, where the speed reduction mechanism is configured to transmit a driving force to a crawler provided on the running unit, a transmission mechanism for transmitting the driving force to the speed reduction mechanism, and an electric motor for applying a rotational force to the transmission mechanism. A motor shaft of the electric motor is positioned higher than a rotational axis of an input shaft of the speed reduction mechanism.

An axle assembly having an electric motor module. The electric motor module may include a rotor, a rotor shaft, a stator, a coolant jacket, an end plate, and a motor housing. The motor housing may encircle a portion of the coolant jacket. The end plate may be disposed outside and may not be received in the motor housing.

A trailer for towing a power vehicle is provided and generally includes a frame and a self propelled tandem wheel assembly. The frame includes an undercarriage chassis, and the self propelled tandem wheel assembly is positioned under the undercarriage chassis. The self propelled tandem wheel assembly includes a rear wheel assembly and a front wheel assembly, and the rear wheel assembly and the front wheel assembly are equally positioned to support the undercarriage chassis.

A universal wheel driving system includes a sun gear receiving power from a power source, a ring gear, of which a rotation axis moves relatively to a rotation axis of the sun gear on a rotation plane parallel to a rotation plane of the sun gear, the ring gear being concentrically connected to a wheel, a gear train allowing relative movement between the rotational axes of the sun and ring gears, and to generate a continuous power transmission between the sun and ring gears, a carrier forming the gear train, and supporting in position a rotation axis of a final pinion engaged with the ring gear constant with respect to the rotation axis of the ring gear, and a plurality of suspension modules providing shock-absorbing and damping during relative movements of the ring gear and carrier with respect to the sun gear.

The wheel assembly includes an arm 51, a wheel 55, a power supply port 60, an electric motor 56 coupled to the wheel 55, and a motor controller 62 for controlling rotation of the electric motor 56. The method of controlling the motion of a motorised object includes defining a target position, sensing a current position of the motorised object and using an output from a processor to control the electric motors to drive the object toward the target position. The golf club storage and transport device 70 includes a body 71 for storing golf clubs and a pair of releasable wheels 75. The device 70 has an assembled configuration and a disassembled configuration.

An axle assembly having an electric motor, a wheel end assembly, and a reduction gear module. The electric motor may have a rotor that is rotatable about a first axis. The wheel end assembly may be rotatable about a second axis that may be disposed above the first axis. The reduction gear module may transmit torque between the electric motor and the wheel end assembly.

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 car body structure includes a bottom plate, a side plate assembly, and a support rod assembly. The side plate assembly includes a first side plate and a second side plate opposite to the first side plate. The first side plate and the second plate are connected to the bottom plate and located on a same side of the bottom plate. An edge of the first side plate facing away from the bottom plate defines at least two first slots, and an edge of the second side plate facing away from the bottom plate defines at least two second slots. The support rod assembly includes at least two support rods, each support rod is snap-engaged with one first slot and one second slot. A surface of the support rod assembly facing away from the bottom plate is a bearing surface. A driving unit is also disclosed.

An embodiment driving module includes a drive unit including a wheel and a drive motor configured to operate the wheel, a suspension unit having a first side coupled to the drive unit, and a steering unit configured to steer the wheel and having a side coupled to a second side of the suspension unit.

A suspension and traction system (MC) is described for vehicles equipped with a frame and a propulsive element (R), which by rolling on the ground (T) is adapted to move the vehicle relative to the ground (T). A rotary electric motor (12) operates two rotors (14, 16) independently controllable from one another to supply two epicycloidal mechanisms (20, 30) whose outer ring gears (28, 38) are independently movable to rotate about the respective solar gear (24, 34) and rigidly connected substantially to a same point (P) of the frame.
