Detailed Description
The specific structure of the clutch driven plate according to the present invention will be described in detail below with reference to the accompanying drawings. In the present invention, unless otherwise specified, the axial direction a, the radial direction R, and the circumferential direction C refer to the axial direction, the radial direction, and the circumferential direction of the clutch driven plate, respectively; one axial side refers to the right side in fig. 5A and 5C, and the other axial side refers to the left side in fig. 5A and 5C.
As shown in fig. 5A to 5C, the structure of the clutch driven plate according to the present invention is substantially the same as that of the clutch driven plate of the related art, and the difference therebetween is that the driven plate main body 2 and the holding plate 6 of the clutch driven plate according to the present invention are different in structure from the driven plate main body 2 and the holding plate 6 of the clutch driven plate of the related art. In addition, the clutch driven disc according to the present invention eliminates the diaphragm spring 8 as compared with the prior art clutch driven disc shown in fig. 1, and achieves a function similar to the diaphragm spring 8 by structural change of the holding plate 6.
As shown in fig. 5A, the clutch driven plate according to the present invention includes friction plates 1, a driven plate main body 2, a damper plate 3, a hub flange 4, damper springs 5, a retaining plate 6, and a hub core 7.
The clutch driven plate has a disk shape as a whole. The driven plate main body 2 and the damping plate 3 are located radially inward of the friction plates 1 and the driven plate main body 2 and the damping plate 3 are fixed together with the friction plates 1 by a connecting member such as a rivet.
The hub flange 4 is mounted in a space surrounded by the driven plate main body 2 and the damper disk 3, and a plurality of damper springs 5 are provided uniformly in the circumferential direction C.
In the present embodiment, a hub core mounting hole is formed in the center of the hub flange 4, and a plurality of internal splines projecting radially inward are formed on the inner peripheral surface of the hub flange 4, which is used to form the hub core mounting hole. The outer peripheral surface of the hub core 7 is formed with a plurality of external splines projecting outward in the radial direction, and the hub core 7 and the hub flange 4 are fitted together in a rotationally fixed manner by fitting the internal splines and the external splines. The hub core 7 is provided in a hub core mounting hole at a central position of the hub flange 4, and an outer peripheral portion of the hub core 7 is provided between the driven plate main body 2 and the damper plate 3 in the axial direction a of the clutch driven plate. The holding plate 6 is snapped onto the driven plate body 2 such that the holding plate 6 and the driven plate body 2 are positioned relative to each other in the circumferential direction C, i.e. relative rotation between the two cannot occur.
As shown in fig. 5B, the driven disk main body 2 has a substantially disk-like shape, and the driven disk main body 2 is provided with a plurality of holes 21 for accommodating damper springs, the plurality of holes 21 being distributed in the circumferential direction C of the driven disk main body 2. An abutting portion 22 abutting against a spring piece portion 63 of a holding disk 6 described later is formed extending along a radial direction R on an inner peripheral edge of the driven disk main body 2, and a radial dimension of the abutting portion 22 is larger than a radial dimension of the spring piece portion 63 so that the spring piece portion 63 can completely abut against the abutting portion 22. Radially outward of the contact portion 22, a projection 24 that contacts the hub flange 4 is provided. In one example, the dimension of the projection 24 is smaller than the dimension of the abutment 22 in the radial direction R. Referring to fig. 3 and 5B, the radial dimension of the lobes 24 of the clutch driven disc according to the present invention is small relative to the radial dimension of the lobes 24 of prior art clutch driven discs, so that a driven disc body 2 of the same size has an abutment 22 of greater radial dimension. A snap groove 23 is formed in the inner peripheral edge of the abutting portion 22, and the snap groove 23 has an arc shape recessed radially outward for fitting with the snap portion 62 of the holding plate 6, so that the holding plate 6 and the driven plate main body 2 are positioned in the circumferential direction C, that is, relative rotation between the two is not allowed.
As shown in fig. 5C, the holding plate 6 includes a holding plate main body 61 having a substantially annular shape, and a plurality of spring pieces 63 protruding outward in the radial direction are formed on the outer peripheral edge of one side in the axial direction of the holding plate main body 61, and the spring pieces 63 extend outward in the radial direction and are inclined toward the other side in the axial direction. The thickness of the spring piece portion 63 may be smaller than the thickness of the retention tray main body 61 in the axial direction a, so that the spring piece portion 63 is easily elastically deformed. In this embodiment, the spring pieces 63 are flat plate-shaped and are grouped in groups of two, and 4 groups of spring pieces 63 are provided at intervals in the circumferential direction of the holding tray main body 61. A plurality of radially outwardly projecting engaging portions 62 are formed on the outer peripheral edge of the holding tray main body 61, and the holding tray main body 61 is mounted on the radially inner side of the driven tray main body 2 by fitting the engaging portions 62 into the engaging grooves 23 of the driven tray main body 2. The engagement portion 62 is configured to be fitted into the engagement groove 23 of the driven plate main body 2, so that the holding plate 6 and the driven plate main body 2 are positioned in the circumferential direction C, i.e., relative rotation therebetween cannot occur.
In the clutch driven plate of the present embodiment, the spring plate portion 63 is located between the driven plate main body 2 and the hub 7. The elastic piece portion 63 abuts on the abutting portion 22 of the driven plate main body 2, one side of the holding plate main body 61 abuts on the hub core 7, and the elastic deformation of the elastic piece portion 63 presses the holding plate 6 and the hub core 7 in the axial direction a, and further presses the hub core 7 and the damper plate 3 in the axial direction a, thereby positioning the hub core 7 in the axial direction a. That is, the driven plate body 2, the holding plate 6, the hub 7, and the damper plate 3 are successively abutted in the axial direction a of the clutch driven plate.
In the present embodiment, the material of the holding plate 6 is plastic that can be elastically deformed. The plastic may be PA66CT10TF20, for example. In one non-limiting example, a 25N axial force applied to the tab portion 63 may cause a 0.5mm axial displacement of the tab portion 63.
The invention also provides a clutch comprising the clutch driven disc.
The specific technical solutions of the present invention are explained in detail in the above specific embodiments, but it should be also noted that:
(1) In the above embodiment, the spring piece portions 63 extend radially outward from the radially inner side (of the radially outermost point) of the click portion 62, and the plurality of spring piece portions 63 are also separated from each other in the circumferential direction C on the radially inner side of the click portion 62. However, the present invention is not limited thereto. For example, the spring piece portions 63 may be entirely located radially outward of the snap-in portion 62, in other words, the spring piece portions 63 may be separated from each other in the circumferential direction C only radially outward of the snap-in portion 62.
In the above embodiment, the spring piece portions 63 are provided in plural sets in the circumferential direction C of the holding tray main body 61, but the present invention is not limited thereto. For example, the elastic piece portion 63 may be provided once in the circumferential direction C of the holding tray main body 61.
(2) In the above embodiment, the spring portion 63 has a flat plate shape, but the present invention is not limited thereto, and the spring portion 63 may have another shape.
