四、操纵性和行驶稳定性 汽车的操纵性能与稳定性能两者是密切相关的。操纵性的丧失往往导致整车侧滑、回转甚至翻车。而稳定性的破坏往往使汽车失去操纵处于危险状态。鉴于这种关系,所以一般统称为操纵稳定性。 1.纵向行驶稳定性 是指农用运输车在纵向坡道上行驶时抗倾翻和滑移的能力。 (1) 农运车在纵向坡道上行驶不发生倾翻的最大坡度,即极限爬坡度为:tgα_(max)=b/h_g b:车辆重心至后较接地点的距离 h_g:车辆重心离地高度
Fourth, maneuverability and driving stability Car’s handling performance and stability are both closely related. The loss of maneuverability often results in vehicle slipping, turning or even overturning. And the destruction of stability often makes the car lose control at a dangerous state. Given this relationship, it is generally referred to as steering stability. 1. Longitudinal driving stability refers to the anti-rollover and slipping ability of agricultural vehicles when driving on longitudinal ramps. (1) The maximum gradient at which the agricultural vehicles do not overturn on the longitudinal ramp, that is, the ultimate grade is: tgα_max = b / h_g b: the distance from the vehicle’s center of gravity to the ground after h_g: height
