某全驱沙漠车悬架侧倾刚度设计研究

Design and Research on Roll Stiffness of an All-wheel Drive Desert Vehicle Suspension

以某4x4全驱沙漠车为研究对象,提出了一种简化的整车数学模型,建立了整车侧倾角与板簧、横向稳定杆刚度的函数关系,得到悬架侧倾角刚度对整车侧倾性能的影响。并介绍了横向稳定杆角刚度计算方法,前后悬架侧倾角刚度匹配原则。

Taking a 4 x4 desert car as the research object.A simplified vehicle model is proposed.The relationship between the roll angle of the whole vehicle and the roll stiffness of the leaf spring and the stabilizer bar is established.The influence of the stiffness of the suspension roll angle on the steering stability of the vehicle.And the calculation method of the angular stability of the transverse stabilizer.Front and rear suspension roll angle stiffness matching principle.
