【摘要】 基于现场试验对TY140型履带推土机外负荷特性进行了研究,在分析试验数据的基础上,确定了一、二挡速度下TY140型履带推土机在铲刀切入、定深切土及运土过程中的牵引力大小,并确定了推土机机重与水平牵引力的关系,为新机型外负荷特性的研究提供了依据。更多还原

【Abstract】 The study on the outer-loading property of TY140 bulldozer is based on the practical experiment.After analyzing the experimental data,the value of traction force under the first and second gear velocity during the blade cut- ting,depth-setting cutting and earthmoving process is determined.Meanwhile,the relationship between weight of bull- dozer and traction force is determined,which is a basis for the outer-loading property study of a new type of bulldozer.更多还原
