参见图 2、图 3和图 4，一种驱动桥半轴离合器，包括主减速器 1，驱动桥 2，半轴离合器压盘 3，驱动桥半轴 4，在驱动桥半轴 4上设有半轴离合器 5， .半轴离合器 5 为能旋转的环形圆盘，半轴离合器可以为膜片弹簧离合器、湿式离合器、金属陶瓷离合器、多片式离合器、牙嵌式离合器、电控离合器、楔块式离合器、滚珠式离合器、转向离合器、非经常接合式离合器或经常接合式离合器，驱动桥为断开式驱动桥、非断开式驱动桥、双联驱动桥或大型拖挂车驱动桥，驱动桥桥壳上有离合器和差速器的安装检查孔，半轴离合器桥壳 6，半轴离合器盖开口向前，通过其边缘的一圈螺栓，固定于半轴离合器飞轮后端面，在半轴离合器飞轮与离合器盖 13之间形成容纳离合器其它部件的空间。压盘 14 为一环形圆盘，位于半轴离合器飞轮与离合器盖 13之间，压盘 14与离合器盖 13之间通过传力机构连接，传力机构除保证压盘 14与离合器盖 13同步旋转外，还允许压盘 14相对离合器盖 13做一定量的轴向位移。从动部分为从动盘 15 (又称离合器片），从动盘 15 的中央设有花键孔，两侧铆接摩擦系数很大的从动盘摩擦片 20，从动盘 15位于半轴离合器飞轮与压盘 14之间，半轴 4穿过离合器盖 13与压盘中心孔，花键部分与从动盘 15的花键孔配合。多个压紧机构被压缩的螺旋弹簧沿圆周均布于从动盘 15与压盘 14之间，弹簧产生的弹力将压盘 14·推向半轴离合器飞轮，从动盘 15被紧紧的夹紧于压盘 14与半轴离合器飞轮之间。分离机构三根分离杠杆 12径向布置，均匀分布于半轴离合器盖 13与压盘 14之间，每根分离杠杆 12的外端与压盘 14铰接，中部与半轴离合器盖 13 铰接形成分离杠杆 12的支点。分离套筒 29松套于半轴输入轴轴承盖形成的圆筒外，位于分离杠杆 12后端。分离套筒 29前端与三根分离杠杆 12之间有一定的间隙，分离套筒本身不能旋转。操纵机构由半轴离合器 5、拉杆和分离叉 7组成，分离叉 7两端支撑于驱动桥壳 6内，可以做一定范围的摆动。传动过程中半轴转矩通过从动盘 15与半轴离合器飞轮和压盘 14之间的静摩擦力矩，传递给半轴后端轴。半轴离合器 5的分离过程为：将半轴离合器通过拉杆使分离叉 7 摆动，推动分离套筒半轴离合器飞轮移动。分离套筒推动分离杠杆 12内端，使分离杠杆 12绕离合器盖 13上的支点摆动，其外端克服压紧弹簧 21的弹力，把压盘 14拉向离合器盖 13方向，将从动盘松开，静摩擦力矩消失，动力传递中断。在半轴离合器的分离过程中，已压缩的压紧弹簧 21被进一步压缩，使得半轴离合器 5需要较大的推力才能使其分离，因此半轴离合器 5采用助力操纵机构，助力操纵机构为气动、电动或液动。离合器的接合过程：若要半轴离合器 5 的拉杆松幵，在分离过程中被压缩的压紧弹簧 21的弹力将压盘 14推向半轴离合器飞轮方向，将从动盘重新夹紧于半轴离合器飞轮与压盘 14之间实现动力的传递。在半轴离合器 5 的接合过程中，通过控制松开拉杆的速度，使得半轴离合器飞轮与压盘 14逐渐将从动盘 15夹紧。在此过程中，通过主、从动部分之间的相对滑动，将汽车阻力矩逐渐加载于半轴离合器飞轮，当半轴离合器 5 完全松开后，主、从动部分恢复同步旋转。 Referring to Figures 2, 3 and 4, a transaxle half-shaft clutch includes a final drive 1, a drive axle 2, a half-shaft clutch platen 3, a drive axle half shaft 4, and is provided on the transaxle axle 4 The half shaft clutch 5, the half shaft clutch 5 is a rotatable annular disc, and the half shaft clutch can be a diaphragm spring clutch, wet type Clutches, cermet clutches, multi-plate clutches, jaw clutches, electronically controlled clutches, wedge clutches, ball clutches, steering clutches, non-recurrently engaged clutches or frequently engaged clutches, drive axles are disconnected Drive axle, non-disconnected drive axle, double drive axle or large trailer drive axle, drive axle housing with clutch and differential mounting check hole, half axle clutch axle housing 6, half shaft clutch cover opening Front, a bolt of a ring on its edge is fixed to the rear end face of the half-shaft clutch flywheel, and a space for accommodating other components of the clutch is formed between the half-shaft clutch flywheel and the clutch cover 13. The pressure plate 14 is an annular disk between the half shaft clutch flywheel and the clutch cover 13, and the pressure plate 14 and the clutch cover 13 are connected by a force transmission mechanism, and the force transmission mechanism ensures that the pressure plate 14 and the clutch cover 13 rotate synchronously. In addition, the platen 14 is allowed to make a certain amount of axial displacement relative to the clutch cover 13. The driven portion is a driven plate 15 (also referred to as a clutch plate). The center of the driven plate 15 is provided with a spline hole, and the driven plate friction plate 20 having a large friction coefficient is riveted on both sides, and the driven plate 15 is located at the half-shaft clutch. Between the flywheel and the pressure plate 14, the half shaft 4 passes through the clutch cover 13 and the center hole of the pressure plate, and the spline portion engages with the spline hole of the driven plate 15. The coil springs of the plurality of pressing mechanisms are circumferentially distributed between the driven plate 15 and the pressure plate 14, and the spring force generated by the spring pushes the pressure plate 14· toward the half shaft clutch flywheel, and the driven plate 15 is tightly held. Clamped between the pressure plate 14 and the half shaft clutch flywheel. The separating mechanism has three separating levers 12 arranged radially, evenly distributed between the half shaft clutch cover 13 and the pressure plate 14, the outer end of each separating lever 12 is hinged with the pressure plate 14, and the middle portion is hinged with the half shaft clutch cover 13 to form a separating lever. The fulcrum of 12. The separating sleeve 29 is loosely sleeved outside the cylinder formed by the half shaft input shaft bearing cap and located at the rear end of the separating lever 12. There is a certain gap between the front end of the separating sleeve 29 and the three separating levers 12, and the separating sleeve itself cannot be rotated. The operating mechanism is composed of a half shaft clutch 5, a pull rod and a separating fork 7, and the two ends of the separating fork 7 are supported in the transaxle case 6, and a certain range of swinging can be performed. During the transmission, the half shaft torque is transmitted to the rear axle of the half shaft through the static friction torque between the driven disc 15 and the half shaft clutch flywheel and the pressure plate 14. The separation process of the axle clutch 5 is as follows: the half shaft clutch is passed through the tie rod to disengage the fork 7 Swing, push the split sleeve half shaft clutch flywheel to move. The separating sleeve pushes the inner end of the separating lever 12, so that the separating lever 12 swings around the fulcrum on the clutch cover 13, and the outer end thereof overcomes the elastic force of the pressing spring 21, and pulls the pressure plate 14 toward the clutch cover 13, and the driven plate is loosened. On, the static friction torque disappears and the power transmission is interrupted. During the separation of the half shaft clutch, the compressed compression spring 21 is further compressed, so that the half shaft clutch 5 requires a large thrust to separate it, so the half shaft clutch 5 employs a power steering mechanism, and the power steering mechanism is pneumatic. , electric or hydraulic. Clutch engagement process: If the tie rod of the half shaft clutch 5 is loose, the elastic force of the compression spring 21 that is compressed during the separation process pushes the pressure plate 14 toward the half shaft clutch flywheel, and the driven plate is re-clamped in half. Power transmission between the axle clutch flywheel and the pressure plate 14 is achieved. During the engagement of the half shaft clutch 5, the speed of the release lever is controlled such that the half shaft clutch flywheel and the pressure plate 14 are gradually clamped from the driven plate 15. During this process, the vehicle resistance torque is gradually applied to the half-shaft clutch flywheel by the relative sliding between the main and driven parts. When the half-shaft clutch 5 is completely released, the main and driven parts resume synchronous rotation.
