为分析配备液压机械无级变速器(Hydro-Mechanical Continuously Variable Transmission,HMCVT)的中小型拖拉机在动力换段过程中的换段品质,在一种特性参数连续可变的HMCVT的基础上,将传统齿轮行星排传动结构变为牵引式行星排传动结构,提出一种多段式HMCVT传动系统。考虑换段时间、液压系统排量比对换段品质的影响,加入牵引式行星排特性参数连续可变的这一变量,对多段式HMCVT传动系统进行AMESim建模仿真分析;在仿真中设定换段时间
t
0
=0.8 s时,对换段品质中的速度降、冲击度、滑摩功3个评价指标在特性参数
k
在1.5~2内进行多参数调节分析。在所设计的三段式HMCVT传动系统L、H换段中,改变特性参数
k
的取值,可使滑摩功最大降低25.6%或冲击度最大降低20.84%;S、L换段中,改变特性参数
k
的取值,可使滑摩功最大降低6.68%,但改变特性参数
k
对冲击度的影响在1%之内变化;总体速度降会随着特性参数
k
的增大而增大。研究结果可为进一步改善换段品质提供参考。
To analyze the stage changing quality of small and medium-sized tractors equipped w
ith hydro-mechanical continuously variable transmission (HMCVT) in the process of power changing
based on a HMCVT with continuously variable characteristic parameters
the traditional gear planetary transmission structure was changed into the traction planetary transmission structure
and a multi-stage HMCVT system was proposed. Considering the influence of changing time and displacement ratio of the hydraulic system on the stage changing quality
AMESim modeling and simulation analysis of the multi-stage HMCVT system were carried out by adding a variable concerning which the characteristic parameters of the traction planetary array were continuously changing. When the change period
t
0
=0.8 s was set in the simulation
multi-parameter adjustment analysis was carried out on the three evaluation indexes of the change period quality
such as velocity drop
impact degree and sliding power
in the characteristic parameter
k
1.5-2. The design of the three-stage HMCVT system can reduce the maximum sliding power by 25.6% or the maximum impact degree by 20.84% by changing the value of the characteristic parameter
k
in the L and H stages. By changing the value of the characteristic parameter
k
in the S and L sections
the sliding work can be reduced by 6.68%
but the impact of changing the characteristic parameter
k
on the impact degree changes within 1%. The overall velocity drop will increase with the increase of the characteristic parameter
k
. The research results can provide reference for further improving the stage changing quality.
