1. Variety
1.1 rubber track can be divided into gear type, wheel hole type and rubber tooth type according to driving mode. The gear tooth shaped rubber track has a driving hole, and the transmission teeth on the driving wheel are inserted into the driving hole to make the track move. The wheel hole type rubber track and metal transmission teeth are inserted into the belt pulley hole to engage the transmission. Rubber teeth drive rubber crawler adopts rubber protrusion instead of metal transmission parts. The inner surface of the track contacts the surface of the driving wheel for friction drive.
1.2 rubber tracks can be divided into agricultural machinery rubber tracks, construction machinery rubber tracks, transport vehicle rubber tracks, snow sweeping vehicle rubber tracks, military vehicle rubber tracks, etc.
2. Basic performance
The basic performance requirements of rubber track traction include traction, non derailment, earthquake resistance and durability. The tractability of rubber track is related to tensile strength, shear strength, bandwidth and transverse stiffness, and also depends on the affected road conditions and loads.
The rubber track has good traction performance. The non falling off performance mainly depends on the data-driven runner diameter, runner configuration and the guiding length of the track. Wheel disengagement often occurs between the driving wheel or tensioning wheel and the runner structure. The distortion of the rubber track leads to stiffness, transverse rigidity, longitudinal compliance, pitch and flange height, which also have some important factors on the non wheel disengagement. Eliminating vibration source is an effective method to reduce environmental vibration and enterprise noise. The vibration of rubber track is related to pitch, runner configuration, different positions of center of gravity, overall performance of rubber and pattern block configuration analysis. Durability shows the ability of rubber track to wear, cut, pierce, crack and break.
