摘　　要：拖拉机的牵引效率是衡量拖拉机牵引作业时发动机功率的有效利用程度,它决定了拖拉机的动力性和经济性指标,影响拖拉机的作业效率和经济性,也是机组选型配备和确定工作参数的重要依据。分析表明影响拖拉机牵引效率的主要因素是滚动效率和滑转效率,凡是影响滚动效率和滑转效率的各项因素都会影响牵引效率,并提出了提高牵引效率的措施,当各因素的措施相互矛盾时,应优先采用改善失常因素的措施。The tractor traction efficiency is the effective utilization of engine power, when the tractor towing the implement. The tractor traction efficiency decides the tractor power and the economical targets, affects the work efficiency and the economical efficiency of the tractor, it is the important basis of the machine group type selection and the working parameters. By analyzing,the rolling and the wheelslip efficiency are the critical factors of the tractor traction efficiency, every kind of factors that influence on the rolling and the wheelslip efficiency affects the traction efficiency. The paper put forwards the measures of enhancing traction efficiency, if the measure of various factors conflict each other, should first adopt the measure of improving abnormal factors.

关 键 词：牵引效率 传动系统效率 滚动效率 滑转效率 滑转率
