The invention discloses a control arm bushing which comprises an inner sleeve, an outer sleeve and a spacer bush arranged between the inner sleeve and the outer sleeve, rubber layers are arranged between the inner sleeve and the spacer bush and between the spacer bush and the outer sleeve, and the outer wall of the middle section of the inner sleeve is in an inwards-concave arc shape. The inner wall of the middle section of the spacer bush is in a concave arc shape, and the outer wall of the middle section is in a convex arc shape. The outer wall of the middle section of the inner sleeve is in the inwards-concave arc shape, the inner wall of the middle section of the spacer bush is also in the inwards-concave arc shape, the outer wall of the middle section of the spacer bush is in the outwards-convex arc shape, the inner sleeve and the spacer bush are each of a variable-cross-section structure, the performance ratio of the bush in all directions can be optimized, the axial rigidity is increased, and deflection and torsional rigidity are reduced; and therefore, the control stability and smoothness of the vehicle can be improved. The spacer bush is made of a plastic material or a composite material of the plastic material and a metal material, and compared with a metal material, the spacer bush is beneficial to reducing the weight of the bush, realizing light-weight design and improving the running economy of a vehicle.
本发明公开了一种控制臂衬套,包括内套、外套及设于内套与外套之间的隔套,所述内套与所述隔套之间、及所述隔套与所述外套之间均设有橡胶层,所述内套中段的外壁为内凹的弧形,所述隔套中段的内壁为内凹的弧形且中段的外壁为外凸的弧形。本发明内套中段的外壁为内凹的弧形,隔套中段的内壁也为内凹的弧形且中段的外壁为外凸的弧形,内套和隔套均为变截面结构,有利于优化衬套各个方向的性能配比,增加轴向刚度而减少偏转和扭转刚度,从而有利于提升车辆的操控稳定性和平顺性。隔套采用塑料材料、或塑料材料和金属材料复合材料,相比于采用金属材料,有利于降低衬套重量,实现轻量化设计,提高车辆运行经济性。
