A tread pattern for a vehicle track, such as an endless track for earth-moving equipment, comprises a plurality of blocks. Each block includes two lateral traction portions extending in substantially opposite directions. The two lateral traction portions are longitudinally aligned and each define a pair of walls defining a plurality of steps. In some examples, each lateral traction portion may define an L-shape. For example, the lateral traction portions of each block may define a protrusion to define the “L” shape, and, in some examples, the protrusions may extend in opposite longitudinal directions. In some examples, the lateral traction portions of each block may be the same shape, where one lateral traction portion may be oriented at about 180 degrees relative to the other lateral traction portion.

A track system for traction of a vehicle (e.g., an agricultural vehicle) in which the track system is designed to better perform when the vehicle is roading, travelling on a side hill or other inclined surface, is braking or undergoing other rim pull events, and/or in other situations, such as by enhancing load distribution (e.g., with wheels that can laterally oscillate and be wider) and/or track tensioning (e.g., with different tensioning stages).

Concrete texturing devices for use on an uncured concrete slab. The concrete texturing devices have a device body, one or more drive systems, at least one articulating arm, and at least one texturing structure. Also disclosed are methods of use.

Track system to be mounted on a vehicle in place of a rotatable OEM tire/wheel assembly, including: A frame. A drive wheel is rotatably mounted on the frame, operatively connectable to the drive shaft of the vehicle, and has a diameter of between 65% and 100% of the OEM tire diameter. Leading and trailing idler wheel assemblies are mounted on the frame. An endless track having an inner surface is disposed around the drive wheel, the leading and trailing idler wheel assemblies. The endless track has an unsupported portion between the drive wheel and one of the leading and trailing idler wheel assemblies. The unsupported portion has a length and a center. The unsupported portion deflects a distance of between 8% and 12% of its length on application of a 25-lb. force at its center.

A vehicle includes a plurality of track systems, a fluid pump, a plurality of fluid lines fluidly connecting the fluid pump to at least some of the tires of the wheels of each of the track systems, a plurality of pneumatic inflation actuators, a plurality of pneumatic deflation actuators, and a system controller. The system controller is in electronic communication with the fluid pump, the plurality of pneumatic inflation actuators, and the plurality of pneumatic deflation actuators. The system controller is operable to selectively adjust fluid pressure in select ones of the wheels of any one of the track systems of the vehicle by actuating corresponding ones of the plurality of pneumatic inflation actuators and the plurality of pneumatic deflation actuators. A track system has at least one of the leading idler wheels, trailing idler wheels, and mid-roller wheels including a tire containing a fluid.

A track assembly includes an elongated main frame supported for pivotal movement on a transverse axis and having opposite end portions supporting a set of end wheels. An endless flexible belt extends around the end wheels and has an upper run and a lower run for engaging the ground. A plurality of longitudinally spaced bogie wheels are positioned below the main frame and engage the lower run of the belt. The bogie wheels are carried by bogie frames supported for vertical movement and also for tilting movement relative to a plane defined by the axes of the end wheels. The bogie frames are urged or biased downwardly against the lower run of the belt by compression members extending from the main frame and preferably in the form of annular rubber spring members.

A novel sprocket for a track drive of a mobile robot may allow for some deformation of the track so that the track better conforms to the surface on which the robot travels. The novel sprocket also may prevent excessive track deformation or deflection that may result in undesirable de-tracking.

A track for traction of a vehicle e.g., a snowmobile, a snow bike, an all-terrain vehicle (ATV), etc.), in which the track may have features to enhance its traction, floatation, and/or other aspects of its performance, including to be lightweight, facilitate turning, enhance acceleration, reduce noise, adapt to different ground conditions, and/or provide other benefits.

Concrete texturing devices for use on an uncured concrete slab. The concrete texturing devices have a device body, one or more drive systems, at least one articulating arm, and at least one texturing structure. Also disclosed are methods of use.

Tracked vehicles and drive systems for tracked vehicles including a guard or shield for a drive motor that deflects debris drawn into a space where the drive motor is located. The guard also provides a longer critical path between the outside of a drive motor assembly and an inside of the drive motor assembly.
