Abstract: A moving mechanism includes a support; a driving device mounted on the support; a controller arranged on the support; two sets of moving assemblies respectively mounted at two ends of the support; wherein each of the moving assemblies includes a track and two synchronous wheels of different diameters arranged inside the track, such that the moving mechanism is functioned and run freely over stairs, rugged road surfaces and all-terrain ground under the action of the driving device and the controller. Besides, the moving mechanism is equipped on electric vehicles and toys. The moving mechanism applies a breakthrough composite structure of a half-wheel-half-track configuration in combination with an additional omni-directional wheel, whereby the moving mechanism and the electric vehicles and toys equipping the same are adaptable to different road surfaces and stairs of various angles, and also convenient and reliable to use.

Abstract: A semi-generic steering knuckle adapter assembly provides predetermined attachment locations for installing a wheel-replacing track system on a steering knuckle. The adapter assembly comprises one or more customized adapting members (e.g. frame(s), plate(s)) configured to be mounted to the steering knuckle of a vehicle, and a generic supporting member (e.g. frame, plate) configured to be mounted to the adapting member(s) and comprising the predetermined attachment locations where the support frame of the track system can be releasably yet rigidly secured. By providing predetermined and preconfigured attachment locations where the wheel-replacing track system can be secured, the adapter assembly allows the track system to be mounted to the vehicle while avoiding attachment at inconvenient and/or weak locations.

Abstract: A bicycle may tow a trailer for the purposes of carrying a heavy or large object across great distances. A motor may be mounted to the trailer which drives a rear wheel of the bicycle. To this end, a transmission is added to the rear hub of the bicycle which is mechanically coupled to the output shaft of the motor. When the trailer is detached or not used in conjunction with the bicycle, the rider does not have to carry the weight of the motor. Also, this setup provides a stable configuration since the bicycle is pulling the trailer.

Abstract: The ratio of the angular speed of a pinion shaft to the angular speed of a steering wheel is computed. The steering torque Tst transferred to the steering wheel is computed as a multiplication product of the ratio of angular speed and the steering torque Tm of the pinion shaft. The steering torque ?Tst transferred to the steering wheel due to actuation of a steered wheel turning angle variable device is computed as a value obtained by subtracting the steering torque Tm from the steering torque Tst. An electric power steering control device is controlled so as to generate a steering torque fluctuation-reducing assist torque corresponding to the steering torque ?Tst.

Abstract: Towing adjustment and coupling techniques may include a retentive lateral trailer adjustment device of a trailer (1) configured to provide lateral adjustment of the trailer (1). In some embodiments, a trailer (1) may include a coupler element (3) and at least one retentive lateral adjustment device configured to provide adjustment in a lateral direction (8) of the coupler element (3). Embodiments may have configurations directed to couplers such as a gooseneck hitch, a fifthwheel hitch, and a pull-type or tongue hitch. Embodiments may also provide a fore-aft position indicator (44) with or without a fore-aft position sensor (50) through which proper positioning of a source of tow power (54) relative to a trailer (1) may be facilitated in a fore-aft direction (7). Corresponding methods are included as embodiments of the invention.
