An electric-motor-driven rigid axle for vehicles. The axle has a body with wheel carriers and points for attachment to a vehicle frame such that, in a cross-section, an upper end of the body faces the frame and a body axis forms a vertical axis extending toward the upper end and intersecting the wheel axis. The axle has electric motors and offset transmissions. The motors drive respective carriers. The transmissions are respectively interposed between the associated motor and carrier. The transmissions enable the shafts of the respective motors to be offset from the wheel axis. The transmissions are arranged such that, in the cross-sectional view, the motor shafts and the wheel axis form intersection points on an offset line which is at an angle of between 1 and 90 degrees to the vertical axis and the vertex is at an intersection point between the wheel axis and the offset line.

The general layout for a front wheel drive, three-wheeled vehicle with two steerable driven wheels in the front of the vehicle, and the motor or motors located in the mid-section of the vehicle. The vehicle is designed for compact motors, in-hub motors, and direct connect motors which allow a significant portion of the vehicle's weight to be moved forward, while integrating location of the passenger seating, steering, and driven wheels allows for a highly stable vehicle. The layout maintains the traditional bucket or bench style seats as found in today's automobiles, and yet allows for weighting and cockpit adaptability for different market demographics.

A mobile vehicle is disclosed herein. It comprises a car body having four wheels, an engine room on a front side thereof and a luggage compartment on a rear side thereof, and at least one drive motor disposed in the engine room or the luggage compartment or both and each of which has a motor body and a rotational shaft passing through a center of the motor body for driving the four wheels to rotate through a driver assembly.

An electric vehicle includes a frame module carrying an electric motor unit and a suspension including, for each wheel, upper and lower oscillating arms connected to a wheel support by swivel joints which define a steering axis of the wheel. The suspension includes two shock absorber devices arranged in horizontal positions and along directions transversal with respect to a vehicle longitudinal direction, which is carried by the frame module centrally on the vehicle. Each shock absorber cylinder is operatively connected to a respective oscillating arm by an oscillating linkage member. Brake discs are arranged at remote positions with respect to the wheels, on two output shafts at two opposite sides of the motor unit, which, in one example, includes two electric motors and two respective gear reducer units from which project the output shafts carrying the brake discs; the latter connected to wheel hubs by respective drive shafts.

A disconnect including: an input hub; an output race including a radially inner surface with ramps; wedge plate segments radially disposed between the input hub and the output race, each segment including a ramp in contact with an outer race ramp; an actuator cage; and an actuator plate. For a connect mode, the input hub, the wedge segments, and the output race transmit torque from an electric motor of an electrically-powered vehicle to a wheel of the vehicle. In a disconnect mode, relative rotation between the input hub and the output race is enabled. To transition from the connect mode to the disconnect mode: the actuator plate is displaced by an actuator; the actuator plate axially displaces the actuator cage; and the actuator cage circumferentially displaces the wedge plate segments to decrease or break frictional contact between the wedge plate segments and the input hub.

In an aspect, a self-balancing two-wheeled vehicle is provided, having a body, and first and second wheels rotatably coupled to the body. The second wheel has at least one lateral roller rotatable about an axis that is one of oblique and orthogonal to a rotation axis of the second wheel. At least one motor is coupled to the second wheel to control rotation of the second wheel and the at least one lateral roller. At least one sensor is coupled to the body to generate orientation data therefor. A control module is coupled to the at least one motor to control operation thereof at least partially based on the orientation data generated by the at least one sensor.

The moving body includes: a vehicle body; a plurality of wheels supported by the vehicle body and configured to rotate; a plurality of motors configured to drive the wheels, respectively; and a rotating base supported by the vehicle body and configured to rotate about a substantially vertical axis.

Apparatuses and systems that yield a zero torque steer for a pallet truck or similar vehicle are disclosed. In an embodiment, a motor is attached to a final drive. The final drive is equipped to a steer assembly such as a tiller that includes a drive wheel that is offset from the steering axis. The offset is determined on the basis of the drive wheel radius, divided by the ratio of the final drive. The ratio of the final drive is determined by selection of the sizes of a first and second gear. In embodiments, the first and second gears provide a right angle drive. The drive wheel creates a torque due to the offset that counteracts torque imposed by operation of the drive motor. Other embodiments may be described and/or claimed.

An automatic device includes: a support; a first motor attached to the support; a second motor attached to the support; a first motor drive unit configured to drive the first motor; a second motor drive unit configured to drive the second motor; a first control unit configured to control the first motor drive unit; and a second control unit configured to control the second motor drive unit. The first control unit includes a first wireless communication circuit configured to wirelessly communicate with the external control device. The first control unit and the second control unit are communicably wired with each other.

To provide a moving apparatus including cylindrical rotating bodies each having a surface section that functions as a driving wheel or a working member. A moving apparatus includes three or more cylindrical rotating bodies, and a plurality of coupling members, each of which couples two of the cylindrical rotating bodies together such that an angle between the cylindrical rotating bodies is smaller than 180, where each of the three or more cylindrical rotating bodies includes a motor, and an exterior body configured to be rotated by the motor, where the three or more cylindrical rotating bodies are configured to form a closed polygonal shape to hold an elongated member R including a rope, whereby the moving apparatus is movable along the elongated member.
