摘要： A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve f(x)=4.641e0.34x. The value “x” represents a horizontal direction and the function f(x) represents a vertical direction.

摘要： State of art techniques utilize active systems for stronger suction in surface crawlers while the passive approaches have limitation in providing consistent grip while moving across curved surfaces or dents. Embodiments herein provide an autonomous surface crawling robot for crawling over surfaces using electro-mechanical assembly for creating strong suction force and enabling the robot to smoothly crawl over flat surfaces, horizontal/vertical/inclined surfaces, curved surfaces, and surfaces with dents. Battery powered motors are used for only mobilization, while mechanical assembly generates suction to provide consistent grip across different type of surfaces. A dual flexible cam profile assembly including a cam profile and a guide rail generates required suction and addresses the technical challenge of maintaining suction across varying surfaces without using external power for suction generation. The dual flexible cam profile provides a robust, less prone to error or slippage type passive crawler mechanism, with consistent grip across uneven the surface.

摘要： A modular frame for a track system is disclosed. The modular frame includes an upper frame member operatively connectable to an axle of a vehicle and removably connectable to a first lower frame member. The first lower frame member is configured to connect with at least one of a support wheel assembly and an idler wheel assembly, and connection of the upper frame member to the first lower frame member confers a first lower frame member-specific function to the track system. Another modular frame, track systems having the modular frames, tensioners and track systems having the tensioners are also disclosed.

摘要： An endless track for traction of an off-road vehicle, such as an agricultural vehicle, an industrial vehicle (e.g., a construction vehicle) or a military vehicle, is provided. The endless track comprises an elastomeric belt-shaped body comprising an inner surface for facing wheels of the vehicle and a ground-engaging outer surface for engaging the ground. The endless track also comprises a plurality of elastomeric lugs, such as drive/guide lugs projecting from the inner surface and/or traction lugs projecting from the ground-engaging outer surface. An elastomeric lug may have a material composition defining an arrangement of zones of different materials which comprises a plurality of zones of different elastomeric materials. The elastomeric lug may exhibit a desired variation of a material property (e.g., a modulus of elasticity) across the arrangement of zones of different materials. A zone of the elastomeric lug may have a dedicated function, such as a sacrificial zone or a wear indicator zone. An elastomeric drive lug may comprise an uneven drive surface, such as an angled or curved surface, for engaging a drive member of a drive wheel of the vehicle.

摘要： A track system for traction of a vehicle (e.g., an all-terrain vehicle (ATV), an agricultural vehicle, etc.) may be designed (e.g., may comprise non-pneumatic tires) to enhance its use or performance and/or that of the vehicle such as, for example, by being lightweight and/or by better handling loads, including, for instance, those resulting from track tension within the track system and/or from unevenness or other aspects of the ground, including encounters (e.g., impacts) with obstacles on the ground (e.g., rocks, portions of trees, debris, bumps, abrupt changes in ground level, etc.). The track system may comprise tension-based non-pneumatic tires.

摘要： A drive component is disclosed. The drive component may include a base of a first material having a first hardness and a plurality of wear inserts of a second material having a second hardness greater than the first hardness. The plurality of wear inserts may extend from an interior of the base to an exterior surface of the base. The base and the plurality of wear inserts may be a composite casting.

摘要： A work machine may include an idler wheel, a drivable track engaged with the idler wheel, and an actuator configured to move the idler wheel to adjust the tension in the drivable track. A controller may actively instruct the actuator to adjust the tension in the drivable track based on the pressure in the actuator and variables associated with the drivable track and the work machine.
