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.

A mower includes a pair of track assemblies positioned on either side of a chassis. The track assemblies include drive wheels coupled to axles driven by an engine. A rocker rigidly mounts to the chassis independently of the engagement of the drive wheel with the axle. The rocker rotatably mounts to a mounting flange fastened to the chassis and includes a plurality of axles to which bogie wheels are mounted. The rocker is vertically below the axle and may be longitudinally centered on the axle or may be asymmetric with respect to the axle. All weight transferred is transferred to a track surrounding the drive wheel and bogie wheels through the rocker assembly engaging the chassis and no weight is transferred to the axle. A suspension may mount the track assembly to the chassis and the track may be long enough to replace front and back wheels.

A continuous track attachment assembly adapted be used on conveying equipment is disclosed. The assembly includes a pair of spaced apart side plates having a plurality of wheel mounting openings therethrough. The side plates have a frame connection opening therethrough. The assembly further includes a plurality of support wheels disposed between the side plates, each of the support wheels including a wheel axle receiving opening therethrough. A center support wheel has a diameter that may be greater than the diameter of two outer support wheels. The assembly further comprises an axle disposed through the wheel mounting openings of the side plate and through the shaft receiving openings of the support wheels to thereby support the support wheels between the side plates while allowing rotation of the support wheels. The assembly further comprises a continuous track disposed about the support wheels.
