摘　　要：目前大多数手动变速箱,倒挡采用滑套方式换挡,挂倒挡时存在卡滞现象,并伴随有明显的冲击声,引发客户强烈抱怨。文章通过研究倒挡卡滞、挂挡冲击的原因,通过受力分析及建立数学模型对影响倒挡挂挡力的几个因素进行了分析,并针对性提出了对应的改进措施,对解决同类问题有较强的借鉴意义。At present,most of the manual gearboxes use sliding sleeve method to shift the verse gear.When the reverse gear is engaged,there is a jamming phenomenon,accompanied by obvious impact sound,causing customer complaints.In this paper,through the study of the causes of reverse gear jam and reverse impact,through the force analysis and the establishment of mathematical model,several factors affecting the reverse gear shifting force are analyzed,and the corresponding improvement measures are proposed,which has a strong reference significance for solving similar problems.

关 键 词：倒挡卡滞 挂挡冲击 数学模型 倒挡力
