履带车辆对不同地表感受到的粗糙程度可以用支重轮位置偏离静平衡位置的程度以及车辆悬挂部件、行走装置的参数来表示,因而可估计在附近一段区域内各种工况下对换挡的要求。在车辆行驶方向上分析履带车辆在不同地面情况下支重轮偏离静平衡位置的各种情况,结合车辆的支重轮个数及履带与地面接触面积,给出表示地面不平状况的计算式。该地面不平状况可用来作为履带车辆自动变速智能换挡的一个输入参数。
The degree of roughness felt by tracked vehicles on different ground surfaces can be expressed by the degree of deviation of the position of the roller bearing from the static equilibrium position and the parameters of the vehicle’s suspension components and the traveling device so that it can be estimated that the shift in various working conditions in a nearby area Request. In the driving direction of the vehicle, the situation that the tracked vehicle deviates from the static equilibrium position under different ground conditions is analyzed. Combined with the number of track rollers and the contact area between the track and the ground, a formula for indicating the uneven ground condition is given. This uneven ground condition can be used as an input parameter for automatic gearshift of tracked vehicles.
