The present invention is a compound planetary gear system which has a moveable sun gear and a lockable sun gear to change the gear ratio between a high gear ratio and a pseudo 1:1 slipping ratio. The system makes use of a ratchet and pawl mechanism to provide a safety backup for when the lockable sun gear is locked. The invention may be used to move the aircraft from a stationary position, for taxiing, and for pre-rotating the wheels prior to landing.

Disclosed herein is a turning motion assistance device for an electric vehicle, adapted to effectively reduce tire wear of the vehicle while at the same time ensuring appropriate turning response.A turning motion assistance device for an electric vehicle including steered wheels 101 and 102, driving wheels 103 and 104, motors 105 and 106, and a steering wheel 108 for controlling a steering angle of the steered wheels 101 and 102, includes a target wheel slip angle calculating unit 151 for calculating a target wheel slip angle from the steering angle, a vehicle state quantity detector for detecting vehicle state quantities, an actual vehicle-body slip angle calculating unit 152 for calculating an actual vehicle-body slip angle from the vehicle state quantities, an actual wheel slip angle calculating unit 153 for calculating an actual wheel slip angle from the actual vehicle-body slip angle and the steering angle, a yawing moment requirement calculating unit 154 for calculating a yawing moment requirement from a difference between the target wheel slip angle and the actual wheel slip angle, and a torque correction data calculating unit 155 for calculating an amount of torque correction for generating the yawing moment required; in this assistance device, a torque that has been corrected in accordance with the amount of torque correction is applied from the motors 105 and 106 to the driving wheels 103 and 104, respectively.

An aviation tire including, a pair of side walls, the side walls having an outer surface, a tread portion spanning a radial outer extremity of the side walls, and a rotating assembly formed on the side wall or the tread portion, the rotating assembly having an increased resistance to wind when located at a lowermost portion of the tire.

An embedded Tire Pressure Monitoring sensor is incorporated into vehicular wheels and a secured central server is used to track the unique identification code of each sensor. The TPMS is installed by the vehicular manufacturer in accordance with the federally mandated TREAD Act of 2000. When a vehicle enters the radius of a first encrypted TPM sensor detection transceiver, its TPM sensor identification codes are recorded and time-stamped via an encrypted TPM sensor detection transceiver. If the vehicle enters the area of a second encrypted TPM sensor detection transceiver, the sensor codes will be recorded and time-stamped a second time, encrypted and sent to the secured central server. Using the two encrypted, time-stamped signals, the secured central server calculates traffic flow data.

A boom support vehicle for supporting elongated loads includes a front dolly which is pivotally connected to a rear dolly at an articulation point. The front dolly includes a front self steering castor axle, and a rear conventional axle. This combination of axles results in stability at high speeds, while also reducing the amount of scuffing which the boom support vehicle experiences as the transporting vehicle and the boom support vehicle negotiate a turn.

A wheel suspension for a motor vehicle is described, in which at least a first and at least a second control arm (1, 2) are coupled in an articulated manner to a wheel carrier (4) carrying a vehicle wheel (3). The wheel suspension has a compensating device (5, 6) for correcting wheel positions, and each control arm (1, 2) has a portion of the compensating device (5, 6) or is connected to a portion of the compensating device (5, 6). The compensating device portions (5, 6) of one wheel are connected to one another by at least one coupling member (7, 8).

A wheel end assembly having a dual wheel configuration includes independently rotating wheel hubs to reduce tire wear. Each wheel hub is supported on an axle spindle via a bearing member. Another bearing member is mounted between the wheel hubs to allow each wheel hub to rotate independently from the other. A fastening assembly retains the hubs on the spindle to prevent linear movement along the spindle.

Disclosed is an airplane tire, and more particularly, is an airplane tire having air pockets, which can allow a tire wheel to rotate using the resistance of air depending on the speed of an airplane upon landing. The airplane tire can alleviate the landing shock of the tire and preventing wear and deformation of the tire by friction. In particular, the airplane tire can shorten a damping distance by virtue of an increased frictional force thereof when an airplane body stops using a tire wheel brake and achieve generation of a sufficient centrifugal force by rotation, thereby contributing to the safe flying of an airplane and the elimination of environmental pollution.

The invention relates to container carriers that are used in ports and terminals. The invention comprises a method, an apparatus and a computer program product for moving a container carrier. The method comprises the steps of lowering the container, causing to disengage the weight of the container and the spreader off the wheels, tuning the wheels to an orientation suitable for a carousel or skew maneuver, lifting the container and starting a carousel or skew maneuver.

A vehicle adaptive steering control apparatus includes a front wheel steering mechanism having a right wheel steering portion and a left wheel steering portion that are independently operable relative to one another. A load detection device measures a condition indicative of vehicle loads at one of the following: the left and right suspension structures and the front wheel steering mechanism. A controller in electronic communication with a steer-by-wire steering wheel assembly, the front wheel steering mechanism and the load detection device, calculates toe angle adjustments for each of the right wheel steering portion and the left wheel steering portion in response to determining a load on each of a left front wheel and a right front wheel based on signals from the load detection device. The controller further makes the toe angle adjustments via changes in turning and steering movements effected by the front wheel steering mechanism.

An agricultural work machine having a chassis with an operating direction and a transport system coupled to the chassis. The transport system includes a plurality of wheels including a first wheel and a wheel repositioning system. The wheel repositioning system is operatively connected to the first wheel. The wheel repositioning system is configured to adjust a position of the first wheel in a direction substantially normal to the operating direction while the chassis is moving in the operating direction.
