Development and Testing of a Friction-Driven Forestry Electric Monorail Car

A friction-driven forestry electric monorail car based on a wheel hub motor is designed with the aim of solving problems low transportation capacity, running speed, large turning radius, and poor stability low-slope mountain monorails. The relationships between minimum radius steering spring elasticity coefficient, body tilt anti-tip distance two chassis wheels was provided by theoretical calculation analysis key parameters dual-chassis structure, device, device. dimensional components were determined. three-dimensional design overall carried out, feasibility verified in kinematic simulation experiments. performance test conducted maximum load full climbing degree, center gravity offset as indicators. results show that has 3.3 m, capacity 300 kg, speed 20 km·h−1 fully loaded, gradient 21°, unilateral vibration amplitude 8 mm or less. double-chassis structure device met requirements. good effectively solves unstable driving current Additionally, environmentally friendly efficient, meeting requirements transporters for forests laying foundation intelligent harvesting forest fruits.
