3. 1 前言 FOREWORD
抗侧滚扭杆是客车转向架的重要部件，其
技术状态的好坏能直接影响乘座舒适度及行车
安全。因此在抗侧滚扭杆的生产、制造、仓储
运输、运用维护过程中必须严格按技术要求，
工艺规范执行。保证抗侧滚扭杆良好的技术状
态及良好的运行状态。
Anti-roll bars are important parts of bogies.
The technique used determines the comfort and
safety of vehicles. So we have to strictly control
the process of production, storage ,transportation
and maintenance to make sure that anti-roll bars
are in good condition.

4. 2 抗侧滚扭杆的结构 STRUCTURES OF ANTI-ROLL BARS
抗侧滚扭杆装置主要由扭杆轴、扭臂、连杆组成、橡
胶衬套等组成（图 1 ）。扭杆轴与扭臂之间为过盈配合连
接。扭杆轴两端与橡胶衬套之间为转动副连接。橡胶衬套
安装在联系枕梁的座孔内。连杆组成两端均安装关节轴承
，上端通过销轴与扭臂连接，下端通过销轴与转向架连接。
An Anti-roll bar device is made up of a torsion bar, torsion arms,
levers, rubber bushing and so on.The torsion bar and the arms are linked
by spline or expansion fitting.The two ends of the torsion bar are fitted
onto self-lubricative bearings of the hangers, which make the torsion bar
running flexible. The hanger assemblies are with rubber buffers which
prevent the torsion bar from axile movement.The two ends of links are
both fixed with spherical bearings or elastic nodes so as to prevent the
transfer of high-frequency shaking to the bodywork.The upper end of the
link is connected with bodywork seat by pin and the lower end is
connected with the lever by pin.The hanger assemblies are connected
with the bogie.

6. 三、抗侧滚扭杆的工作原理
FUNCTIONARY THEORY OF ANTI-ROLL BARS
铁路高速、准高速客车转向架中央悬挂装置基本上都采用橡胶
空气弹簧悬挂装置。空气弹簧的运用，极大地改善了车辆的垂向
振动性能，但同时也出现了车体侧滚振动的角刚度随之变得相对
柔软。因此，在运行中车辆车体侧滚角位移增大，尤其当车辆通
过道岔和曲线时，呈现车体侧滚角度大、晃动次数多，使旅客感
到不舒适。为了确保车体具有良好振动性能，在转向架中央悬挂
装置中间（无摇动台转向架和车体间）设置抗侧滚扭杆装置。
Most of the center suspension devices of high speed car bogies adopt
air-springs .The use of air-springs has greatly improved the
performance of vertical shaking,but at the same time the angle
stiffness of bodywork’ shaking becomes lower .Thereby when the
angle displacement increases, especially when the vehicle crosses
through a turnoff or a curve ,the bodywork’s roll angle increases and
shakes more times ,these all make the passengers uncomfortable .To
decrease shaking of bodywork, we set anti-roll bars to the center
suspension device of the bogie.

7. 抗侧滚扭杆在转向架上的安装位置
The installation position of anti-roll bars on bogie

8. 其原理：当转向架左右空气弹簧发生相反方向的垂
直位移（车体侧滚）时，水平放置的两个扭臂相对扭
杆分别有一个相反的力和力矩作用，使扭杆承受扭矩
而产生扭转变形，起扭杆弹簧作用。扭杆弹簧的反扭
矩，总是与车体产生侧滚角位移的方向相反，以约束
车体的侧滚运动 ( 如下图）。
The principle:
When the air-springs transform in the converse
vertical directions ,the two horizontal
end links bring converse forces to the torsion bars
,which makes the torsion bar transforms so that the
anti-roll bar acts as a torsion-spring.The converse
torque is always VS
bodywork’ angle displacement ,which controls the
bodywork’ side movements.

10. 当左右空气弹簧为同方向垂直位移时，因扭杆
两端为转轴同轴承支承，两扭臂只使扭杆产生同向转
动，而不发生扭杆弹簧作用，而不影响车体的浮动、
横摆等振动。不影响中央悬挂装置的中央弹簧的柔软
弹性。
When the air-springs transform in the same vertical
direction, the two torsion bars turn at the same
direction ,the anti-roll bar doesn’t act as torsion-
springs .So it has no effect on the bodywork’s floating
,transverse shaking and so on. It doesn’t affect the
flexibility of the center suspension device either.

12. 四、抗侧滚扭杆的特点 TRAITS OF ANTI-ROLL
BARS
抗侧滚扭杆装置的作用特征，确定它应设置在空气
弹簧（中央弹簧）的上下支承部分之间。有联系枕梁的
CRH3 型动车组，抗侧滚扭杆设置在联系枕梁与构架之
间（图 5 ）；无摇动台但是采用旁承支重的 SW-160 型
转向架设置在摇枕与构架间； CW-200K 型转向架无心
盘，无摇动台装置，抗侧滚扭杆设置在车体与构架之间。
Due to the trait of anti-roll bar ,it should be fixed between the
bearings of center spring. For 209HS and CW-2 with vibration
desk, it should be fixed between bolster and support plate of
spring. For 206PK and SW-160 without bolster but with side plate
supporting , the bogie is fixed between bolster and truss for CW-
200K ,without bogie centre plate or bolster ,the anti-roll bar is fixed
between bodywork and truss.

14. 虽然各种抗侧滚扭杆组成安装位置有所不同，但都有相同的
主要性能要求： Although diversified anti-roll bars have
different fixing positions, they have the same major
performance requirements:
1 、应有适宜的抗侧滚扭转刚度。
They should have appropriate anti-roll torsion stiffness.
2 、应具有能适应空气弹簧上下支承两个部分间相对运动的
随动性。
They should have agile movement between bearings of
air-springs.
3 、在垂向、横向、纵向的三个方向，应均尽量减少对中央
悬挂装置的刚度的影响。
In the directions of vertical, horizontal and longitudinal,
They can reduce the influence on stiffness of the center
suspension.
4 、应注意防止高频振动向车体部位的传递。
They should prevent the transferring of high-frequency
shaking to the bodywork .
