Abstract

This study evaluates the performance of an agricultural tractor with a maximum power of 92.4 kW (125.6 hp), equipped with different wheel and tire configurations. The experiment was carried out in the field, with a randomized block design in a trifactorial scheme, with two wheel and tire configurations (double wheel and diagonal tire; single wheel and radial tire), three mass-power ratios (61, 67, and 74 kg kW -1 ), and three levels of partial loads imposed on the drawbar (24, 27, and 36 kN), on firm soil covered with vegetation. The data were recorded by means of electronic instrumentation installed in the tractor. The results indicate that the double wheel and diagonal tire configuration showed better performance regarding traction force, traction power, and traction efficiency, as well as lower specific fuel consumption. In turn, the simple wheel and radial tire configuration showed the lowest values of driving wheel slipping. The best traction performance was obtained with the mass-power ratio of 67 kg kW -1 for the double wheel and diagonal tire configuration, and 61 kg kW -1 for the single wheel and radial tire configuration.

农用拖拉机不同车轮和轮胎配置的性能

本研究评估了一台最大功率为92.4千瓦（125.6马力）的农用拖拉机的性能，该拖拉机配备了不同的车轮和轮胎配置。试验在现场进行，采用三因素方案中的随机块体设计，采用两轮和轮胎配置（双轮和斜向轮胎；单轮和子午线轮胎），三种质量功率比（61、67和74 kg kW-1），以及施加在牵引杆上的三个水平的部分载荷（24、27和36 kN），在植被覆盖的坚实土壤上进行。数据是通过安装在拖拉机上的电子仪器记录的。结果表明，双轮和对角轮胎配置在牵引力、牵引功率和牵引效率方面表现出更好的性能，并且比油耗更低。反过来，简单的车轮和子午线轮胎配置显示出最低的驱动轮打滑值。双轮和斜交轮胎配置的质量功率比为67 kg kW-1，单轮和子午线轮胎配置的重量功率比为61 kg kW-2时，获得了最佳的牵引性能。
