The invention relates to a cab front suspension assembly and a vehicle, and the cab front suspension assembly comprises two front suspension upper supports which are arranged at intervals in the width direction of a vehicle body; the two ends of the swing arm assembly are in one-to-one correspondence with the two front overhang upper supports, and the swing arm assembly is hinged to the corresponding front overhang upper supports; the other two ends of the swing arm assembly are in one-to-one correspondence with the two lower supports, and are hinged with the corresponding lower supports; and each rigidity-variable assembly is respectively hinged between one front overhang upper bracket and one lower support seat. The rigidity section at the bottom of the variable-rigidity assembly absorbs vibration transmitted from the chassis end, so that high-frequency vibration and impact transmitted to the cab end are attenuated to the maximum extent; the rigidity interval located on the upper portion intervenes to absorb the remaining transmitted vibration, so that when the whole vehicle is in different working conditions, different rigidity intervals intervene, and then better comfort is brought to a driver at the lowest cost.
本发明涉及一种驾驶室前悬置总成及车辆,其包括:两个前悬上支架,在车身宽度方向上,两个所述前悬上支架间隔设置;摆臂总成,所述摆臂总成的两端与两个所述前悬上支架一一对应,并与对应的所述前悬上支架之间铰接;两个下支座,所述摆臂总成的另两端与两个所述下支座一一对应,并与对应的所述下支座之间铰接;两个变刚度总成,每个所述变刚度总成分别铰接在一个所述前悬上支架和一个下支座之间。变刚度总成底部的刚度区间吸收底盘端传递来的振动,使传递到驾驶室端的高频振动及冲击得到最大化的衰减;位于上方的刚度区间介入来吸收剩余传递来的振动,使得整车处于不同工况时,不同刚度区间介入,进而以最低的成本给驾驶员带来更好的舒适性。
