Rubber track pads are annular belts made of neoprene rubber, glass fiber cords, and nylon elastic fabric, driven by a synchronous belt mesh. They feature low ground pressure, high traction, minimal vibration when climbing stairs, low noise levels, excellent performance on wet surfaces, resistance to pavement damage, and fast travel speeds. Rubber track pads are primarily used in various intelligent tracked robots—including industrial robots, specialized operation robots, service robots, and micro-robots—to perform tasks such as locomotion, obstacle crossing, and stair climbing.
　　The rubber components of the rubber track pad include tread-side rubber, bottom rubber, carcass rubber, and ply rubber, among others.
　　(1) Pattern-side adhesive
　　The side rubber prevents mechanical damage and premature wear of the belt, transmits the vehicle’s traction and braking forces to the road surface, and absorbs and dissipates vibrations generated by the rubber track plates during movement. The running surface of the tread rubber consists of tread pattern blocks and grooves of various shapes, including parallel, single-ladder, double-ladder, and herringbone patterns. The selection and height design of the tread pattern blocks should be based on adapting to terrain conditions and enhancing traction, while also taking cost into consideration. The configuration should avoid stress concentration. By altering the resistance to crack propagation and reducing the early damage to the rubber caused by stone compression against the tread blocks, this material exhibits excellent wear resistance, puncture resistance, tear resistance, anti-sticking properties, flexural resistance, and aging resistance.
　　(2) Primer
　　The base adhesive is applied beneath the pattern-side adhesive and serves to cushion vibrations and impacts. During the operation of rubber track plates, the base adhesive repeatedly deforms, generating significant heat. Therefore, the base coat should exhibit low heat generation, high thermal conductivity, high elasticity, and excellent adhesion performance.
　　(3) Carcass rubber and ply rubber
　　The cord fabric should possess high elasticity and softness, good thermal conductivity and air tightness, excellent dynamic performance and heat resistance, as well as strong adhesion to the carcass material. The cord fabric adhesive should exhibit good adhesion to the cord fabric and excellent calendering performance.
　　Operating environment for rubber track pads:
　　(1) The operating temperature range for rubber track pads is generally between -25℃ and 55℃.
　　(2) Chemicals, engine oil, and salt from seawater can accelerate the aging of tracks; therefore, tracks used in such environments must be thoroughly cleaned afterward.
　　(3) Road surfaces with sharp protrusions (such as rebar, stones, etc.) can cause external injuries to rubber tracks.
　　(4) Road curbs, ruts, or uneven road surfaces can cause cracks in the tread pattern on the ground side of the rail edges; therefore, the steel cord can be used continuously without damage.
　　(5) Crushed stone and crushed stone pavement can cause premature wear on the rubber surface in contact with the load-bearing wheels, leading to small cracks. Severe water ingress can result in the core falling out and steel wires breaking.
