传动系统布置型式和速度波动

研究了采用“A”型架的车辆在振动过程中传动系统万向节安装角度的变化情况,及其引起的传动系统转速波动,传动系统的布置型式可以是Z型或W型,比较了不同的布置型式对传动系统转速波动的影响,后桥振动过程中传动轴转过的角度小于“A”型架转过的角度时,采用W型布置产生的速度波动要优于Z型布置,给出了Z型和W型布置的传动系统中后桥安装角度的求解方法,以及对于特定的采用“A”型架的车型传动系统采用Z型还是W型布置的判断方法。

Analysis on Driveline Arrangment and its Angular Velocity Fluctuation

The change of deviation angle of universal joints and the angular velocity fluctuation of the driveline in a vehicle using A frame during vibration was analyzed. The installed angle of the rear bridge determines whether the driveline is Z or W arrangement which affects the angular velocity fluctuation in driveline differently during vehicle vibration. When the swing angle of the driveshaft is smaller than that of A frame, Style W is better than Style Z. Equations were given to solve the installed angle of the rear bridge in Z and W arrangements. An approximate way was proposed to decide which arrangement is better for a certain vehicle with A frame.
