A special suspension-type tracked underwater robot adaptable to ultra-soft geological conditions comprises traveling mechanisms, wherein the traveling mechanisms are track-mud sled structures, the mud sled structures are fixedly arranged on two sides of each track, and the bottoms of the mud sled structures are higher than the bottoms of the tracks and are provided with arched plate heads; the arched plate heads are provided with plate water-jet devices capable of spraying water forwards; and in the traveling process of the traveling mechanisms, and the arched plate heads press water downwards to form a water film at the bottoms of the mud sled structures together with the water sprayed by the plate water-jet devices, so that the traveling mud resistance is reduced, and the robot can stably advance under ultra-soft geological conditions. The special suspension-type tracked underwater robot further comprises a propelling mechanism, an adjustment device, an operating module, and the like, can autonomously advance on a seabed, can suspend in water, can repair itself when broken, and can achieve detailed operations.

A seal includes an annular body defining a radial direction, an axial direction, and a circumferential direction; and further defines a cross-sectional area including a perimeter. The perimeter may comprise a first axial extremity, a second axial extremity, an outer radial extremity, and an inner radial extremity. The perimeter may include a first axial extremity defining surface and a second axial extremity defining surface, a first concave arcuate surface interposed between the inner radial extremity and the second axial extremity, and a second concave arcuate surface interposed between the outer radial extremity and the second axial extremity.

A seal according to an embodiment of the present disclosure comprises an annular body defining a radial direction, an axial direction, and a circumferential direction; and further defining a cross-sectional area including a perimeter. The perimeter may comprise a first axial extremity, a second axial extremity, an outer radial extremity, and an inner radial extremity. The perimeter includes a first axially extending surface defining the outer radial extremity and an inner radial convex arcuate surface defining the inner radial extremity.

For track vehicles having drive assemblies that are susceptible to buildup of mud and debris that can result in damage to the track and drive assembly, clearing members are provided that clear buildup while avoiding contact with components of the track vehicle as the track frame oscillates.

A device for cleaning the tracks of a track-driven vehicle comprising a mounting plate, at least one positioning arm connected to and extending from the mounting plate, and at least one brush assembly attached to and extending from a positioning arm, where the mounting plate, positioning arm, and brush assembly are configured so that when the mounting plate is mounted to a vehicle the brush is positioned to clean the track of the vehicle.

A component for a track-type machine comprises a body, a through-bore extending through the body forming an inner wall, and a bushing located in the through-bore. The bushing comprises a bearing surface, an outer surface engaging the inner wall, a flange extending from the outer surface and extending into the inner wall, and retention features located in the outer surface proximate the flange. The retention features comprise voids in the bushing filled-in by material of the body. Methods of manufacturing a component for a track-type system comprises casting-in-place a bushing with a flange and retention features into the component.

A track link assembly comprises a plurality of link subassemblies. Each link subassembly may include a pair of links coupled together. Each link may include a first aperture and a second aperture, and the second aperture of each link may be larger than the first aperture. The track link assembly may include a pin element extending through the first aperture of a first link and the second aperture of a second link in each link subassembly. The track link assembly may include a bushing element with a central opening. The bushing element may surround a portion of the pin element and extend through the second aperture of the second link of each link subassembly. The bushing element may include at least one hole configured to couple a track shoe to the bushing element.

An undercarriage assembly for a rope shovel comprising a crawler frame having a crawler body, a first leg and a second leg, the first leg having a first lateral crawler frame bore therethrough and the second leg having a second lateral crawler frame bore therethrough; a roller component disposed at least partially below the crawler body between the first leg and the second leg, the roller component having a lateral roller component bore therethrough; a first crawler frame bushing having a first flanged end, the first crawler frame bushing disposed in and through the first lateral crawler frame bore; a roller component bushing having a first flanged end, the roller component bushing being disposed in and through the lateral roller component bore; wherein the first flanged end of the first crawler frame bushing abuts the first flanged end of the roller component bushing.
