摘要： Example techniques have been presented for providing tracked vehicles with deployable towing wheels. Such techniques involve a track vehicle having a vehicle body, a track coupled to the vehicle body, and a wheel assembly coupled to the vehicle body. The wheel assembly includes a wheel and is operable to assume a towing position in which at least a portion of the wheel extends below the track and enables the tracked vehicle to be towed on the wheel without the track making ground contact.

摘要： The Reconfigurable Wheel-Track (RWT) device is a novel mechanism that allows a wheel to transform into a track, and vice versa. The wheel mode allows a vehicle to travel quickly over smooth and semi-rough terrain, then, on-the-fly, transform rapidly into a powered track mode for crossing extreme terrain. The reconfigurable wheeltrack device comprises several main components: an outer tire/tread, a drive mechanism for driving the tread when in track mode and a reconfiguration mechanism that facilitates the transformation from wheel mode to track mode and vice versa. The reconfigurable wheel-track includes sensing, actuation, and controls to facilitate efficient and effective transitions, and securely maintain each wheel and track shape.

摘要： A replacement mobility assembly for a walk-behind, powered device (10) may include first and second drivable components, a mobility assembly frame, and an adaptation assembly. The powered device may be provided with an original mobility assembly (40) that is to be removed from coupling with a drive assembly and a chassis (15) of the powered device prior to installation of the replacement mobility assembly. The first and second drivable components may each be of a different type than corresponding drivable components of the original mobility assembly. The first and second drivable components may be operably coupled to the mobility assembly frame. The adaptation assembly may be configured to enable the mobility assembly frame to be operably coupled to the chassis and the first and second drivable components to be operably coupled to the drive assembly.

摘要： Interchangeable track systems for interchangeable deployment with vehicle wheels on a forestry harvester vehicle having a front axle and a rear axle may include a pair of front roller frame mount arms and a pair of rear roller frame mount arms configured for mounting on the front axle and the rear axle, respectively. A pair of front track assemblies and a pair of rear track assemblies may be configured for removable mounting on the pair of front roller frame mount arms and the pair of rear roller frame mount arms, respectively. Each of the pair of front track assemblies and the pair of rear track assemblies may include an elongated roller frame configured for pivotal attachment to the corresponding one of the pair of front roller frame mount arms and pair of rear roller frame mount arms. A front idler roller and a rear idler roller may be carried by the roller frame. A track may be trained on the front idler roller and the rear idler roller. A sprocket may be configured for driving engagement by a corresponding one of the front axle and the rear axle, with the sprocket drivingly engaging the track.

摘要： The stair-climbing stroller is a baby stroller with retractable front and rear wheels for use on flat travel surfaces and a pair of tracks for use on inclined travel surfaces including, but not limited to, staircases. The front wheels are coupled to a pivoting front wheel support shaft and the rear wheels are coupled to a pivoting rear wheel support shaft. A wheel retract motor located on the underside of the stroller may cause a retraction drive shaft to pivot the front and rear wheel support shafts, retracting the wheels. When the front and rear wheels retract, the stroller may be lowered such that the left and right track rest on the ground. Left and right track motors may then be used to drive the stroller up an inclined travel surface using the tracks.

摘要： A tactical transport cart manually navigable by a single human operator over both topographic and hydrographic terrains has a frame, a payload-supporting area on the frame, a pair of wheels or other terrain-engaging transport propulsion members attached to the frame, a handle structure attached to the frame, at least one motor connected in driving relation to the transport propulsion members, a battery for providing motive power to the motor, and a control device connected between the battery and the motor for controlling supply of motive power to the motor, with a switch device mounted on the handle structure for selective actuation and deactuation of the motor. The frame, transport propulsion members and handle structure are cooperatively dimensioned and configured for movement of the cart over ground surfaces of topographic terrains and for partially and fully submerged movement over water-covered surfaces of hydrographic terrains.

摘要： A crawler device 2 includes a crawler unit 5. The crawler unit 5 includes a first support 10 extending along a first rotational axis L1, a pair of crawler structures 20A, 20B mounted on the first support 10 and a pair of ground contacting structures 30A, 30B mounted on the first support 10. The pair of ground contacting structures 30A, 30B are arranged outside of the pair of crawler structures 20A, 20B in a direction in which the pair of crawler structures 20A, 20B are opposed to each other. The crawler unit 5 is supported by second supports 41, 42 such that the crawler unit 5 is rotatable about the first rotational axis L1. An outer periphery of the crawler unit 5 having a circular cylindrical configuration includes first zones Z1 occupied by the pair of crawler structures 20A, 20B and second zones Z2 occupied by the pair of ground contacting structures 30A, 30B alternately arranged in a circumferential direction.

摘要： 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.
