具体实施方式Detailed ways
下面结合附图与具体实施方式对本发明作进一步详细描述：Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
实施例一：Embodiment one:
如图1所示，本发明提供的一种抗侧滚扭杆装置，包括扭杆1、扭臂2、垂向连杆3和阻尼装置。As shown in FIG. 1 , an anti-roll torsion bar device provided by the present invention includes a torsion bar 1 , a torsion arm 2 , a vertical link 3 and a damping device.
其中，扭杆1的杆体横穿车体，扭杆1的杆体作为扭力弹簧提供扭转刚度。在扭杆1的两端分别连接一个扭臂2，扭臂2与扭杆1之间刚性连接在一起，或扭臂2与扭杆1的杆体作为一体结构，且扭臂2与扭杆1之间的夹角为90°。扭杆1的两端通过扭杆座4连接在构架上，扭杆座4固定在构架上，扭杆座4可相对扭杆1的杆体转动。扭臂2的另一端通过垂向连杆3与车体10连接，对于安装有枕梁的车辆，扭臂2的另一端通过垂直连杆3与枕梁连接。垂向连杆3底部的一端通过弹性节点5或球铰与扭臂2连接，垂向连杆3顶部的一端同样通过弹性节点6或球铰与车体10或枕梁连接，垂向连杆3起到将扭臂2与车体10相连传递车体10与扭臂2间位移及载荷的作用。Wherein, the rod body of the torsion bar 1 traverses the vehicle body, and the rod body of the torsion bar 1 serves as a torsion spring to provide torsional stiffness. A torsion arm 2 is respectively connected to the two ends of the torsion bar 1, and the torsion arm 2 and the torsion bar 1 are rigidly connected together, or the torsion arm 2 and the body of the torsion bar 1 are used as an integral structure, and the torsion arm 2 and the torsion bar 1 The angle between them is 90°. The two ends of the torsion bar 1 are connected on the frame through the torsion bar seat 4, the torsion bar seat 4 is fixed on the frame, and the torsion bar seat 4 can rotate relative to the body of the torsion bar 1. The other end of the torsion arm 2 is connected with the vehicle body 10 through the vertical connecting rod 3 , and for a vehicle equipped with a corbel, the other end of the torsion arm 2 is connected with the bolster through the vertical connecting rod 3 . One end of the bottom of the vertical link 3 is connected to the torsion arm 2 through an elastic node 5 or a spherical hinge, and one end of the top of the vertical link 3 is also connected to the car body 10 or the corbel through an elastic node 6 or a spherical hinge. 3 plays the role of connecting the torsion arm 2 with the vehicle body 10 and transferring the displacement and load between the vehicle body 10 and the torsion arm 2 .
如图1所示，本实施例中，阻尼装置采用的是减振器7，减振器7在车体一侧的一个垂向连杆3上，与减振器7并联连接有复位弹簧8，减振器7和复位弹簧8集成在一起安装。As shown in Figure 1, in the present embodiment, what the damping device adopts is a shock absorber 7, and the shock absorber 7 is on a vertical connecting rod 3 on one side of the vehicle body, and a return spring 8 is connected in parallel with the shock absorber 7 , The shock absorber 7 and the return spring 8 are integrated and installed together.
本实施例中优选，将一侧的垂向连杆3完全用减振器7替代，将减振器7的一端通过弹性节点5或球铰与扭臂2连接，减振器7的另一端通过弹性节点6或球铰与车体10连接，起到将扭臂2与车体相连传递车体与扭臂2间位移及载荷的作用。同时，扭臂2与扭杆1之间刚性连接在一起，将垂向连杆3、减振器7和复位弹簧8的载荷转化为作用在扭杆1杆体上的扭矩。Preferably in this embodiment, the vertical link 3 on one side is completely replaced by a shock absorber 7, one end of the shock absorber 7 is connected to the torsion arm 2 through an elastic node 5 or a ball joint, and the other end of the shock absorber 7 The elastic node 6 or the ball joint is connected with the vehicle body 10 to connect the torsion arm 2 with the vehicle body and transfer the displacement and load between the vehicle body and the torsion arm 2 . At the same time, the torsion arm 2 is rigidly connected to the torsion bar 1, and the load of the vertical link 3, the shock absorber 7 and the return spring 8 is converted into a torque acting on the body of the torsion bar 1.
车体倾摆时相对扭臂2发生运动，在往复倾摆振动过程中，减振器7通过产生的阻尼力耗散车辆倾摆振动能量。减振器7产生的阻尼力在一定条件下与车体相对扭臂2的运动速度呈比例关系，基本趋势是相对速度越大阻尼力越大、相对速度越小阻尼力越小。这样当车体倾摆运动剧烈，与扭臂2间的相对运动速度大时，减振器7提供较大阻尼力与扭杆1杆体、扭臂2及另一侧垂向连杆3共同作用降低车体倾摆位移。When the vehicle body tilts, it moves relative to the torsion arm 2, and during the reciprocating tilting vibration process, the shock absorber 7 dissipates the vibration energy of the vehicle tilting through the generated damping force. The damping force generated by the shock absorber 7 is proportional to the moving speed of the vehicle body relative to the torsion arm 2 under certain conditions. The basic trend is that the greater the relative speed, the greater the damping force, and the smaller the relative speed, the smaller the damping force. In this way, when the tilting movement of the car body is severe and the relative movement speed between the torsion arm 2 and the torsion arm 2 is high, the shock absorber 7 provides a large damping force to work together with the body of the torsion bar 1, the torsion arm 2 and the vertical connecting rod 3 on the other side. Reduced body roll displacement.
在车辆通过不平顺线路时，车体倾摆运动相对较缓，与扭臂2间的相对运动速度较小，减振器7提供的阻尼力则会随之减小，使得抗侧滚扭杆装置提供的抗侧滚载荷不至于过大，进而不会给车辆增加过多的附加扭转刚度，可提高车辆对于线路不平顺的适应性。When the vehicle passes through an uneven road, the tilting motion of the vehicle body is relatively slow, and the relative movement speed between the vehicle body and the torsion arm 2 is small, and the damping force provided by the shock absorber 7 will decrease accordingly, so that the anti-roll torsion bar The anti-rolling load provided by the device will not be too large, and thus will not add too much additional torsional rigidity to the vehicle, which can improve the adaptability of the vehicle to uneven roads.
复位弹簧8与减振器7并列设置在车体与扭臂2间，起到复原的效果，复位弹簧8可根据具体情况选择安装或不安装。Back-moving spring 8 and shock absorber 7 are arranged side by side between car body and torsion arm 2, play the effect of restoration, and back-moving spring 8 can be selected to install or not install according to specific conditions.
实施例二：Embodiment two:
如图2所示，与实施例一不同之处在于，本实施例中，阻尼装置采用的是扭转阻尼器9，并将扭转阻尼器9安装在扭杆1上。安装时，将扭杆1断开，扭转阻尼器9的两端安装在断开处的两端扭杆1上，扭转阻尼器9与扭杆1之间刚性连接。As shown in FIG. 2 , the difference from the first embodiment is that in this embodiment, the damping device is a torsional damper 9 , and the torsional damper 9 is installed on the torsion bar 1 . During installation, the torsion bar 1 is disconnected, and the two ends of the torsion damper 9 are installed on the torsion bar 1 at both ends of the disconnection, and the torsion damper 9 and the torsion bar 1 are rigidly connected.
在剧烈车辆倾摆时，扭转阻尼器9提供足够的阻尼力使扭杆1扭转，避免车辆发生过大倾摆，且可吸收倾摆振动能量缓解倾摆振动，避免车辆抗侧滚刚度过大，降低车体倾摆位移，提高轨道车辆脱轨安全性。When the vehicle is violently tilted, the torsional damper 9 provides sufficient damping force to twist the torsion bar 1, avoiding excessive tilting of the vehicle, and can absorb the energy of the tilting vibration to alleviate the tilting vibration, and avoid excessive anti-rolling rigidity of the vehicle , reduce the tilting displacement of the car body, and improve the derailment safety of the rail vehicle.
在车辆通过不平顺线路时，车体倾摆运动相对较缓，与扭臂2间的相对运动速度较小，扭转阻尼器9提供的阻尼力则会随之减小，使得抗侧滚扭杆装置提供的抗侧滚载荷不至于过大，进而不会给车辆增加过多的附加扭转刚度，可提高车辆对于线路不平顺的适应性。When the vehicle passes through an uneven road, the tilting motion of the vehicle body is relatively slow, and the relative motion speed between the vehicle body and the torsion arm 2 is small, and the damping force provided by the torsion damper 9 will decrease accordingly, so that the anti-roll torsion bar The anti-rolling load provided by the device will not be too large, and thus will not add too much additional torsional rigidity to the vehicle, which can improve the adaptability of the vehicle to uneven roads.
扭转阻尼器9也可以安装在扭杆1和扭臂2的连接处，这样安装结构更加简单，拆装也更加方便。The torsional damper 9 can also be installed at the junction of the torsion bar 1 and the torsion arm 2, so that the installation structure is simpler and the assembly and disassembly are more convenient.
