0引言在拖拉机作业过程中,会伴有拖拉机驾驶室的剧烈颤动现象,通常采用在驾驶室中安装减振机构的方式来消减驾驶室的剧烈颤动。目前使用的减振机构,大部分为单级减振机构,应用后在一定程度上削减了由于外力作用所引发的驾驶室颤动,但是由于拖拉机作业环境比较恶劣,驾驶室内颤动剧烈,在使用单级减振机构后驾驶人员依然感受到剧烈的颤动,拖拉机驾驶室舒适度不高。为了克服单级减振机构中存在的不足,现设计一种拖拉机驾驶室两级减振机构,其结构简单,拆装方便,可为使用者提供舒适的驾驶环境。
0 Introduction During the tractor operation, there will be violent chattering of the tractor cab, usually by adopting a damping mechanism in the cab to reduce the violent chatter of the cab. Currently used damping mechanism, most of the single-stage damping mechanism, after the application to some extent reduced due to external forces caused cab vibration, but due to harsh tractor operating environment, severe vibration in the cab, the use of single After the level of vibration damping mechanism drivers still feel violent vibration, the tractor cab comfort is not high. In order to overcome the shortcomings of the single-stage vibration reduction mechanism, a two-stage vibration damping mechanism of the tractor cab is designed. The structure is simple, the disassembly and assembly is convenient, and a comfortable driving environment can be provided for the user.
