具体实施方式Detailed ways
本独立悬架装置为左右对称结构,为了图示简洁起见,只显示了其左侧结构的示意图。The independent suspension device has a left-right symmetrical structure, and for the sake of brevity in the illustration, only the schematic diagram of the structure on the left side is shown.
如图1所示,本独立纵梁1,下横臂2,上横臂3,减振器4,弹簧5,稳定杆6,稳定杆吊耳7。As shown in Figure 1, the independent longitudinal beam 1, the lower cross arm 2, the upper cross arm 3, the shock absorber 4, the spring 5, the stabilizer bar 6, and the stabilizer bar lug 7.
纵臂1由圆截面的管材1a弯曲而成。如图2、3所示,其前端焊接有一套管1b,其间压装衬套1h,通过衬套1h弹性的连接于车身上。在纵臂1的后段焊接有三个支架,分别为:The trailing arm 1 is bent from a
支架1c,其下部焊接于纵臂管1a上,用于安装轮毂轴承单元等轮边装置,承受车轮负载。The
支架1d,其下部焊接于纵臂管1a上,侧部焊接于支架1c上,与支架1c共同形成一个U型空间,并设计对穿通孔,用于安装上横臂3。The lower part of the
支架1e,为一U型板,焊接于纵臂管1a的后段,并设计对穿通孔,用于安装下横臂2。The bracket 1e is a U-shaped plate, which is welded to the rear section of the
轴销1f,粗段穿过纵臂管1a,两侧焊接,细段用于安装减振器下端的衬套,并攻有螺纹。The
类似的,轴销1g用于安装稳定杆吊耳上端的衬套。Similarly, the
再回到图1。下横臂2,为冲压焊接件,外端通过衬套连接与纵臂支架1e上,内端同样通过衬套与托架连接。Go back to Figure 1 again. The lower cross arm 2 is a stamped weldment, the outer end is connected to the trailing arm bracket 1e through a bushing, and the inner end is also connected to the bracket through a bushing.
类似的,上横臂3为锻件,两端压装衬套;一端与托架连接,另一端插入纵臂1的支架1c与1d形成的U型空间内,通过长螺栓安装。Similarly, the upper cross arm 3 is a forging, and the two ends are press-fitted with bushings; one end is connected to the bracket, and the other end is inserted into the U-shaped space formed by the
减振器4与弹簧5分开并行布置。弹簧5安装于下横臂2的弹簧托盘与托架弹簧托盘之间,上下两端各设计有减振垫(图中未显示),以减小噪声传递。且此安装方式使悬架的结构更为紧凑,有利于装车时的后悬架模块化分装。The shock absorber 4 is arranged separately from the spring 5 in parallel. The spring 5 is installed between the spring tray of the lower cross arm 2 and the bracket spring tray, and the upper and lower ends are respectively designed with damping pads (not shown in the figure) to reduce noise transmission. Moreover, this installation method makes the structure of the suspension more compact, which is beneficial to the modular subassembly of the rear suspension during vehicle loading.
减振器7布置在上横臂3与下横臂2之间,上端通过弹性支架连接于车身;下端为套筒结构,压装衬套,插入于纵臂1的轴销1f上,用螺母固定。The shock absorber 7 is arranged between the upper cross arm 3 and the lower cross arm 2, and the upper end is connected to the vehicle body through an elastic bracket; the lower end is a sleeve structure, a bushing is pressed, inserted on the
稳定杆6通过橡胶材料的固定支座(图中未显示)固定在后 托架底部,通过稳定杆吊耳7吊挂在纵臂上;稳定杆吊耳7下端连接稳定杆,为球销结构;上端连接纵臂,为衬套结构,插入于纵臂1的轴销1g上,用螺母固定。The stabilizer bar 6 is fixed on the bottom of the rear bracket through a fixed support made of rubber material (not shown in the figure), and is hung on the longitudinal arm through the stabilizer bar lug 7; the lower end of the stabilizer bar lug 7 is connected to the stabilizer bar, which is a ball pin structure ; The upper end is connected to the trailing arm, which is a bushing structure, inserted into the
由上所述的众多零件,构成了本实例的独立悬架装置。By above-mentioned numerous parts, constitute the independent suspension device of this example.
在本实例中,较佳的是:In this instance, it is preferable to:
从整车竖直方向看,纵臂衬套1h的轴向大致朝向下横臂2与后托架的连接点方向,运动过程中,悬架绕此轴线上下摆动;同时上横臂的摆动则保证悬架在运动中的外倾角满足较好的变化规律。Viewed from the vertical direction of the vehicle, the axial direction of the trailing arm bushing 1h is generally toward the connection point of the lower cross arm 2 and the rear bracket. During the movement, the suspension swings up and down around this axis; at the same time, the swing of the upper cross arm Ensure that the camber angle of the suspension in motion meets a better change rule.
在整车竖直方向看,下横臂2与纵臂1连接点,比其与托架连接点靠前。就整车横向来看,上横臂3衬套刚度小于下横臂2衬套。纵臂铰接刚度相对较小,从而使传递到车身的振动尽可能的小;且其径向刚度大于轴向刚度。Viewed in the vertical direction of the entire vehicle, the connection point between the lower cross arm 2 and the trailing arm 1 is ahead of the connection point between the lower cross arm 2 and the bracket. As far as the vehicle is viewed laterally, the stiffness of the upper cross arm 3 bushing is less than that of the lower cross arm 2 bushing. The hinge stiffness of the trailing arm is relatively small, so that the vibration transmitted to the vehicle body is as small as possible; and its radial stiffness is greater than the axial stiffness.
该设计的优点在于:The advantages of this design are:
如图4所示,在整车竖直方向看;在整车转弯受到侧向力的时候,侧向力通过纵臂支架1c传递到横臂与纵臂上。如上所述,纵臂衬套1h刚度最小,因而变形量最大,且向内、向后变形;而下横臂2衬套刚度最大,因而向内侧变形量最小,且产生向后的微小摆动;从而使车轮产生一个正的前束,导致车辆的转向不足,提高了转向稳定性。As shown in Figure 4, viewed from the vertical direction of the vehicle; when the vehicle is turned and subjected to lateral force, the lateral force is transmitted to the cross arm and the longitudinal arm through the
类似的,在整车制动的时候,车轮受到地面提供的沿整车向后的制动力,通过纵臂支架1c传递到纵臂与横臂上。类似的,纵臂铰接1h产生较小的向内、较大的向后变形量。此时,两个横臂则绕着各自与托架的连接点相应地向后摆动。上述下横臂2最长,且其与纵臂1连接点较与托架连接点靠前,故该点产生较大的向外的变形量;使车轮产生一个正的前束,提高了制动时的稳定性。Similarly, when the vehicle is braked, the wheels receive the braking force provided by the ground along the vehicle backwards, and are transmitted to the trailing arm and the cross arm through the trailing
且在本实例中,前束调节装置为:纵臂1的前端衬套1h与车身安装的孔径大于安装螺栓的外径,;该设计可以方便的横向、纵向调整纵臂前铰接点的位置,从而达到微调前束、轴距的目的。And in this example, the toe-in adjustment device is as follows: the
由上述介绍可以看出,本悬架装置结构简单、紧凑,易于布置,增加了行李箱、油箱的可用空间,尤其是纵臂的结构简单,成本低廉,具有较好的经济性;同时本悬架具有较好的操控性与舒适性,同时改善了车辆的NVH性能。It can be seen from the above introduction that the suspension device has a simple and compact structure, is easy to arrange, and increases the usable space of the trunk and the fuel tank. The frame has better handling and comfort, and at the same time improves the NVH performance of the vehicle.
