具体实施方式Detailed ways
下面参照附图描述本发明的示例性实施方式。应当理解，这些具体的说明仅用于示教本领域技术人员如何实施本发明，而不用于穷举本发明的所有可行的方式，也不用于限制本发明的范围。Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, and are not used to exhaust all possible ways of the present invention, nor to limit the scope of the present invention.

参照图1至图3，根据本发明的转矩限制装置包括盖10、从动盘21、压盘30、碟形弹簧40和叶片弹簧50。1 to 3 , the torque limiting device according to the present invention includes a cover 10 , a driven plate 21 , a pressure plate 30 , a disc spring 40 and a leaf spring 50 .
该转矩限制装置例如可以用于车辆，特别是混合动力车辆，其中，盖10用于与发动机输出端的飞轮抗扭地(不能相对转动地)连接，从动盘21用于与变速器或电机抗扭地连接。The torque limiting device can be used, for example, in vehicles, in particular hybrid vehicles, in which the cover 10 is connected in a rotationally fixed (non-rotatable) manner to the flywheel on the output side of the engine, and the driven disk 21 is used in connection with the transmission or the electric machine in a rotationally fixed manner. Twisted connection.
可选地，从动盘21包括摩擦片，摩擦片位于外周部。Optionally, the driven disc 21 includes a friction plate, which is located at the outer periphery.
应当理解，虽然多数情况下，车辆内的动力是从发动机端传至变速器端，然而，在不同的工作模式下，动力也有可能从变速器端传至发动机端，因此，从动盘21并不一定是从动的零部件，其相对于盖10也有可能属于主动件。以下为描述方便，将以从发动机端指向变速器端的动力传递路径为例，描述盖10和从动盘21的连接关系和工作原理。It should be understood that although in most cases, the power in the vehicle is transmitted from the engine end to the transmission end, however, in different working modes, the power may also be transmitted from the transmission end to the engine end, therefore, the driven disc 21 does not necessarily It is a driven part, which may also belong to an active part relative to the cover 10 . For the convenience of description below, the connection relationship and working principle of the cover 10 and the driven plate 21 will be described by taking the power transmission path from the engine end to the transmission end as an example.
盖10包括盖主体11和钩部12。The cover 10 includes a cover body 11 and a hook portion 12 .
盖主体11呈环形的盘状，盖主体11的外周部形成有向径向内侧凸出的多个钩部12。多个钩部12在周向C上间隔开地分布。The cover main body 11 has an annular disk shape, and a plurality of hooks 12 protruding radially inward are formed on the outer peripheral portion of the cover main body 11 . The plurality of hooks 12 are distributed in the circumferential direction C at intervals.
钩部12与盖主体11形成为一体。例如，钩部12是通过对盖主体11冲裁后折弯而形成的。替代地，所述钩部也可以是连接或附接至盖主体11的单独部件，例如销钉或环形止挡件。The hook portion 12 is formed integrally with the cover body 11 . For example, the hook portion 12 is formed by punching the cover body 11 and then bending it. Alternatively, the hook may also be a separate part connected or attached to the cover body 11, such as a pin or an annular stop.
盖主体11的位于轴向端部的端壁110和钩部12之间形成收容空间，该收容空间用于至少部分地收容摩擦片、压盘30和碟形弹簧40。An accommodation space is formed between the end wall 110 at the axial end of the cover body 11 and the hook portion 12 , and the accommodation space is used to at least partially accommodate the friction plate, the pressure plate 30 and the disc spring 40 .
具体地，压盘30将从动盘21的摩擦片压靠于端壁110，或者说，摩擦片被夹设在压盘30和端壁110之间。压盘30对摩擦片所施加的压力由碟形弹簧 40提供。Specifically, the pressure plate 30 presses the friction plate of the driven plate 21 against the end wall 110 , or in other words, the friction plate is sandwiched between the pressure plate 30 and the end wall 110 . The pressure exerted by the pressure plate 30 on the friction plate is provided by the disc spring 40.
碟形弹簧40的外周部抵接于钩部12，以获得位于外周部的支点；碟形弹簧40的内周部抵接于压盘30，以获得位于内周部的支点。The outer peripheral portion of the disc spring 40 abuts against the hook portion 12 to obtain a fulcrum at the outer peripheral portion; the inner peripheral portion of the disc spring 40 abuts against the pressure plate 30 to obtain a fulcrum at the inner peripheral portion.
可选地，同时参照图1和图3，碟形弹簧40的外周部形成有向径向外侧延伸的、辐条状的指部41。指部41与钩部12相配合而抵接于钩部12的朝向端壁110的面。在周向C上，指部41的宽度与钩部12的宽度大致相等。Optionally, referring to FIGS. 1 and 3 at the same time, the outer peripheral portion of the disc spring 40 is formed with spoke-shaped fingers 41 extending radially outward. The finger portion 41 cooperates with the hook portion 12 to abut against the surface of the hook portion 12 facing the end wall 110 . In the circumferential direction C, the width of the finger portion 41 is substantially equal to the width of the hook portion 12 .
可选地，钩部12的朝向指部41的面上形成有多个凸起状结构，该凸起状结构能在周向C和径向R上对指部41起到限位作用；或者说，钩部12的朝向指部41的面上形成有凹槽，指部41能容纳于凹槽中而实现碟形弹簧40相对于盖10在周向C上和径向R上的定位。Optionally, a surface of the hook portion 12 facing the finger portion 41 is formed with a plurality of protruding structures, and the protruding structures can limit the position of the finger portion 41 in the circumferential direction C and the radial direction R; or That is, the surface of the hook portion 12 facing the finger portion 41 is formed with a groove, and the finger portion 41 can be accommodated in the groove to realize the positioning of the disc spring 40 relative to the cover 10 in the circumferential direction C and the radial direction R.
指部41的外径大于钩部12的内径。由于指部41和钩部12在周向C上均是不连续的，因此在安装过程中，可以通过插空的方式，例如先将指部穿过相邻钩部12之间的空隙，而将指部41在轴向A上伸至钩部12和端壁110之间。之后，在周向C上转动碟形弹簧40，使指部41与钩部12在周向C上对齐。The outer diameter of the finger portion 41 is larger than the inner diameter of the hook portion 12 . Since both the finger portion 41 and the hook portion 12 are discontinuous in the circumferential direction C, during the installation process, the finger portion can be inserted through the space between the adjacent hook portions 12 by inserting the space. The fingers 41 are extended in the axial direction A between the hooks 12 and the end wall 110 . After that, the disc spring 40 is rotated in the circumferential direction C so that the fingers 41 and the hooks 12 are aligned in the circumferential direction C. As shown in FIG.
进一步优选地，碟形弹簧40的外周部除了具有与钩部12相配合的指部41之外，还具有沿轴向延伸的抵靠部，该抵靠部能够在碟形弹簧40的外周部区域中与压盘30压靠。Further preferably, the outer peripheral portion of the disc spring 40 has an axially extending abutting portion in addition to the finger portion 41 matched with the hook portion 12 , and the abutting portion can be placed on the outer peripheral portion of the disc spring 40 The area is pressed against the platen 30 .
通过调整碟形弹簧40的尺寸(例如变形程度)，可以调整压盘30对摩擦片所施加的轴向压力，从而调整摩擦片受到的最大静摩擦力(即在转矩限制装置传递转矩的工作过程中，摩擦片两侧受到的来自于压盘30和盖主体11的静摩擦力)。该静摩擦力对应于转矩限制装置所能传递的转矩的上限值。By adjusting the size of the disc spring 40 (such as the degree of deformation), the axial pressure exerted by the pressure plate 30 on the friction plate can be adjusted, so as to adjust the maximum static friction force on the friction plate (that is, in the work of the torque limiting device transmitting torque) During the process, the two sides of the friction plate are subjected to the static friction force from the pressure plate 30 and the cover main body 11). This static friction force corresponds to the upper limit value of the torque which the torque limiting device can transmit.
当输入端(例如盖10)的转矩小于或等于该上限值时，盖10与摩擦片不发生相对转动，输出端(从动盘21)所接收的转矩等于输入端的转矩。当输入端的转矩大于该上限值时，盖10与摩擦片之间产生滑摩而发生相对转动，输出端所接收的转矩等于该上限值。When the torque of the input end (eg cover 10 ) is less than or equal to the upper limit value, the cover 10 and the friction plate do not rotate relative to each other, and the torque received by the output end (driven disc 21 ) is equal to the torque of the input end. When the torque at the input end is greater than the upper limit value, sliding friction occurs between the cover 10 and the friction plate to cause relative rotation, and the torque received at the output end is equal to the upper limit value.
压盘30与盖10通过多个叶片弹簧50相连。本实施方式中，压盘30与盖10之间连接有3个叶片弹簧50(同时参照图4)，三个叶片弹簧50在周向C上间隔均匀(间隔120°)地设置。The pressure plate 30 is connected to the cover 10 through a plurality of leaf springs 50 . In this embodiment, three leaf springs 50 are connected between the pressure plate 30 and the cover 10 (see also FIG. 4 ).
叶片弹簧50呈弧形，其一端51例如通过铆钉固定于压盘30，其另一端52例如通过铆钉固定于端壁110。The leaf spring 50 is arc-shaped, and one end 51 of the leaf spring 50 is fixed to the pressure plate 30 by, for example, rivets, and the other end 52 is fixed to the end wall 110 by, for example, rivets.
叶片弹簧50使压盘30和盖10之间在轴向A上具有一定的弹性、在周向C上能传递扭矩而不容易发生相对转动，并且，多个在周向C上分布的叶片弹簧50也帮助压盘30完成相对于盖10的对中。The leaf spring 50 has a certain elasticity in the axial direction A between the pressure plate 30 and the cover 10, and can transmit torque in the circumferential direction C without relative rotation, and a plurality of leaf springs are distributed in the circumferential direction C. 50 also assists in the centering of the platen 30 relative to the cover 10 .
应当理解，本申请还提供一种包括该转矩限制装置的扭矩传递装置和车辆。It should be understood that the present application also provides a torque transmitting device and a vehicle including the torque limiting device.
扭矩传递装置包括转矩限制装置和减振部件20。The torque transmitting device includes a torque limiting device and a damping member 20 .
从动盘21与减振部件20相连。其中，减振部件20包括减振弹簧22、法兰和侧板，减振弹簧22以传递扭矩地方式设置在法兰与侧板之间。法兰与侧板中的一个与从动盘21连接，而法兰与侧板中的另一个连接到轴部23。The driven disk 21 is connected to the damping member 20 . The damping component 20 includes a damping spring 22, a flange and a side plate, and the damping spring 22 is disposed between the flange and the side plate in a manner of transmitting torque. One of the flange and the side plate is connected to the driven disc 21 , and the other of the flange and the side plate is connected to the shaft portion 23 .
