41 0 、环形衔铁420、动端面齿轮 4 30 、定端面齿轮4 4 0 和弹 复位件 4 50 As shown in FIG. 2, in the single-motor hybrid power system of this embodiment, the second clutch 400 includes: a ring electromagnet 41 0 , a ring armature 420, a moving end gear 4 30 , a fixed end gear 4 4 0 and elastic reset. Pieces 4 50 . 4 20 固定在动端面齿轮430上, 二者同轴心设置,优选地,环形衔铁420套置固定在动端面齿轮430 ,这样可以进一步缩短第二离合器400的轴向尺寸,进而缩小单电机混合动力系统的体积。 The ring armature 4 20 is fixed on the moving end face gear 430, and the two are arranged coaxially . Preferably, the ring armature 420 is sleeved and fixed on the moving end face gear 430. This can further shorten the axial size of the second clutch 400, and further Reduce the size of single-motor hybrid systems. 41 0 相距一定距离,动端面齿轮430和定端面齿轮440相啮合(如图2所示);当环形电磁铁410通电时,环形衔铁420被磁吸至环形电磁铁410 ,驱使动端面齿轮430脱离定端面齿轮 4 40 ,弹 复位件 4 50 安装在动端面齿轮430上,具体地弹性复位件450包括定位板45 1 和多个弹簧452,多个弹簧卡在定位板 4 51 与动端面齿轮430之间且呈圧缩状态, 于在环形电磁铁 4 10 断电后,驱使动端面齿轮430复位与定端面齿轮440相啮合。 When the ring electromagnet 410 is not energized, the ring armature 420 is spaced a certain distance from the ring electromagnet 410 , and the moving end gear 430 and the fixed end gear 440 are engaged (as shown in FIG. 2); when the ring electromagnet 410 is energized, the ring The armature 420 is magnetically attracted to the ring-shaped electromagnet 410 , which drives the moving end face gear 430 away from the fixed end face gear 4 40. The elastic reset member 4 50 is installed on the moving end face gear 430. Specifically, the elastic reset member 450 includes a positioning plate 45 Multiple springs 452, multiple springs are clamped between the positioning plate 4 51 and the moving end gear 430 in a contracted state, and are used to drive the moving end gear 430 to reset and fix the fixed end gear 440 after the ring electromagnet 4 10 is powered off. Phase meshing. 41 0 包括:励磁线圈和铁芯;沿圆周绕线的励磁线圈通过树脂密 固定于铁芯的 部。 In one embodiment of the present invention, the ring-shaped electromagnet 410 of the second clutch 400 includes: an excitation coil and an iron core; the excitation coil wound along the circumference is fixed to the inside of the iron core with a resin seal .
的机械连接方式如下: 电机300的端盖上设有环形卡 310 ,该环形 槽310与电机300的主轴同轴心,第二离合器400的环形电磁铁4 1 0 嵌装在环形卡槽310内,由于环形电磁铁4 1 0 的高度小于环形卡槽310的 深,形成了环形 止口。 As shown in FIG. 2, the mechanical connection of the second clutch 400 to the motor 300 and the driving shaft of the automobile is as follows: An end cover of the motor 300 is provided with an annular card slot 310 which is coaxial with the main shaft of the motor 300 The ring-shaped electromagnet 4 10 of the second clutch 400 is embedded in the ring-shaped slot 310. Since the height of the ring-shaped electromagnet 4 10 is smaller than the slot depth of the ring-shaped slot 310 , a ring-shaped notch is formed. 向端面上具有与上述环形电磁铁 41 0 嵌装在环形卡槽3 1 0 内所形成的环形凹止口相适配的环形凸止口;当环形衔铁420被磁吸至环形电磁铁4 1 0 上时,环形衔铁420上的环形凸止口嵌装在环形电磁铁410与环形卡槽3 1 0 形成的环形凹止口内,进一步地,环形凸止口的端面上具有环形凸槽,该环形凸槽与环形凸止口同 心设置,环形凸槽的两个槽边能够嵌装在环形凹止口内。 The axial end surface of the ring armature 420 has a ring-shaped convex stop adapted to the ring-shaped concave stop formed by the ring- shaped electromagnet 41 0 embedded in the ring slot 3 1 0 ; when the ring armature 420 is magnetically attracted to When the ring-shaped electromagnet 4 1 0 is on, the ring-shaped convex stop on the ring-shaped armature 420 is embedded in the ring- shaped concave stop formed by the ring- shaped electromagnet 410 and the ring- shaped groove 3 1 0. Further, the end face of the ring-shaped convex stop has An annular convex groove is provided coaxially with the annular convex stop , and two groove edges of the annular convex groove can be embedded in the annular concave stop. 向的花键套置在电机300的主轴上,使得环形衔铁420和动端面齿轮430 固定组成的整体既能随电机300的主轴同步转动, 能沿电机300的主轴轴向移动;定端面齿轮4 4 0 固定在汽车的驱动 上,二者同 心设置,弹性复位件450的定位板 4 51 固定在电机300的主轴上,用于在环形电磁铁410断电后,驱使环形衔铁 4 20 和动端面齿轮430固定组成的整体沿电机300的主轴轴向移动,复位至与定端面齿轮440相啮合。 The moving end gear 430 of the second clutch 400 is sleeved on the main shaft of the motor 300 through an axial spline, so that the fixed assembly of the ring armature 420 and the moving end gear 430 can rotate synchronously with the main shaft of the motor 300, and can also rotate along the main shaft of the motor 300. The main shaft of the motor 300 moves axially; the fixed-face gear 4 4 0 is fixed on the drive shaft of the car , and the two are arranged coaxially. The positioning plate 4 51 of the elastic reset member 450 is fixed on the main shaft of the motor 300 and is used in the ring shape. After the power of the electromagnet 410 is turned off, the fixed integral part of the ring armature 4 20 and the moving end face gear 430 is moved axially along the main axis of the motor 300 and reset to be engaged with the fixed end face gear 440.
