Abstract
Description
Technical Field
[0001] This utility model relates to the field of clutch technology, and in particular to an anti-slip spline sleeve for a clutch driven disc assembly. Background Technology
[0002] The spline sleeve has an axial positioning function. The spline sleeve is matched with the gearbox input shaft through precision-machined splines. Its inner splines and the outer splines of the input shaft form a multi-tooth meshing structure. This design can not only transmit torque, but also limit the axial runout of the driven plate through multi-point contact, ensuring that the driven plate, flywheel and pressure plate maintain parallel contact during power transmission, and the shock absorber spring and damping mechanism work together.
[0003] The clutch driven plate assembly typically includes a damping spring and a damping plate, such as a spring steel plate riveted to the damper plate. When torque is transmitted, the axial constraint of the spline sleeve and the elastic deformation of the damping spring together absorb torsional vibration, preventing driven plate sway caused by engine speed fluctuations. Its spline tooth profile design, such as involute or rectangular teeth, can reduce stress concentration and further reduce the risk of sway. The material strength of the spline sleeve and the precision of the spline work together to combat the driven plate sway phenomenon.
[0004] In common clutch driven plate spline sleeves, the connection between the sleeve and the clutch disc is made by welding, and the precision spline is used to achieve the anti-slip effect. However, the precision spline causes the sleeve and the gearbox input shaft to generate high temperature during operation, which affects the service life.
[0005] In view of this, this application proposes an anti-slip spline sleeve for a clutch driven disc assembly. Utility Model Content
[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-slip spline sleeve for a clutch driven disc assembly.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: A clutch driven plate assembly anti-sway spline sleeve includes a clutch disc, a positioning mounting ring installed inside the clutch disc, a sleeve structure jointly installed inside the positioning mounting ring, and a transmission spline shaft slidably connected inside the sleeve structure. The sleeve structure includes a mounting base ring that is tightly fitted inside the positioning mounting ring. The mounting base ring is slidably connected to the clutch plate. An extension sleeve is mounted on the mounting base ring. A spline groove is formed in both the mounting base ring and the extension sleeve. The mounting base ring and the extension sleeve are splinedly engaged with the transmission spline shaft.
[0008] As a further preferred embodiment of this technical solution, the positioning mounting ring is provided with mounting grooves arranged in a circumferential array, and the mounting bottom ring is provided with mounting sliders arranged in a circumferential array corresponding to the mounting grooves.
[0009] As a further preferred embodiment of this technical solution, a sliding mounting ring is slidably connected to the mounting base ring, the sliding mounting ring being adapted to the mounting slider, and mounting bolts distributed in a circumferential array are mounted together on the mounting base ring, the sliding mounting ring, and the positioning mounting ring.
[0010] As a further preferred embodiment of this technical solution, a weight-reducing groove is provided inside the extension collar, and ventilation grooves distributed in a circumferential array are provided on the extension collar at positions corresponding to the weight-reducing groove.
[0011] As a further preferred embodiment of this technical solution, the ventilation slots are staggered, and the position of the weight-reducing slot inside the extension collar is matched with the transmission spline shaft.
[0012] As a further preferred embodiment of this technical solution, the ventilation slot is connected to the weight reduction slot, and the bottom surface of the ventilation slot is inclined toward the weight reduction slot.
[0013] This utility model has the following beneficial effects: This invention features a bottom ring installed within the clutch disc and positioning mounting ring, which is extended by an extension ring. This allows the bottom ring and extension ring to slide on the outer contour of the mounting bolts, ensuring enhanced anti-sway performance of the clutch disc during use. Furthermore, the mounting slider on the bottom ring engages with the mounting groove on the positioning mounting ring, ensuring a stable connection between the bottom ring, clutch disc, and positioning mounting ring via mounting bolts. This creates a stable whole between the clutch disc, positioning mounting ring, and sleeve structure. Additionally, a weight-reducing groove within the extension ring lowers its weight, reducing the inertia generated when the clutch disc separates from the flywheel. Simultaneously, staggered ventilation grooves are created on the outer contour of the extension ring corresponding to the weight-reducing grooves. These ventilation grooves connect to the weight-reducing grooves, allowing air to flow through the extension ring and thus cooling the sleeve structure and transmission spline shaft.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] This utility model provides the following technical solution: like Figures 1 to 4 As shown, a clutch driven plate assembly anti-sway spline sleeve includes a clutch disc 1, a positioning mounting ring 2 installed inside the clutch disc 1, a sleeve structure 3 jointly installed inside the positioning mounting ring 2 and the sleeve structure 3, and a transmission spline shaft 4 slidably connected inside the sleeve structure 3. The sleeve structure 3 includes a mounting bottom ring 31 that is tightly fitted inside the positioning mounting ring 2. The mounting bottom ring 31 is slidably connected to the clutch plate 1. An extension collar 35 is mounted on the mounting bottom ring 31. A spline groove is opened in both the mounting bottom ring 31 and the extension collar 35. The mounting bottom ring 31 and the extension collar 35 are splinedly engaged with the transmission spline shaft 4.
[0018] It should be noted that by sliding between the mounting base ring 31 and the positioning mounting ring 2, and by installing the extension collar 35 on the mounting base ring 31, and by opening spline grooves in the mounting base ring 31 and the extension collar 35 to engage with the splines on the transmission spline shaft 4, and by installing the extended mounting base ring 31 and the extension collar 35 in the clutch plate 1, it is possible to ensure that the clutch plate 1 slides on the transmission spline shaft 4, thereby preventing the clutch plate 1 from wobble.
[0019] On the other hand, by installing the bottom ring 31 within the clutch plate 1 and the positioning ring 2, the installation of the bottom ring 31 and the extension ring 35 with the clutch plate 1 is stable. This ensures the stability of the clutch plate 1 during operation and avoids the occurrence of swaying without affecting the function of the clutch plate 1.
[0020] like Figures 2 to 4As shown, the positioning mounting ring 2 has mounting grooves 5 arranged in a circumferential array, and the mounting bottom ring 31 has mounting sliders 33 arranged in a circumferential array corresponding to the mounting grooves 5.
[0021] A sliding mounting ring 32 is slidably connected to the mounting base ring 31. The sliding mounting ring 32 is adapted to the mounting slider 33. The mounting base ring 31, the sliding mounting ring 32 and the positioning mounting ring 2 are all equipped with mounting bolts 34 arranged in a circumferential array.
[0022] It should be noted that by installing an array of mounting sliders 33 on the mounting base ring 31 and opening mounting grooves 5 in the positioning mounting ring 2 corresponding to the mounting sliders 33, the mounting base ring 31 is embedded in the positioning mounting ring 2 in conjunction with the mounting sliders 33. This ensures that the mounting base ring 31 is positioned and installed in the clutch plate 1, and also ensures the stability between the mounting base ring 31, the clutch plate 1, and the positioning mounting ring 2.
[0023] On the other hand, the sliding mounting ring 32 and the mounting slider 33 are embedded on the other side, and threaded holes are opened on the mounting bottom ring 31, the sliding mounting ring 32 and the positioning mounting ring 2, and mounting bolts 34 are installed accordingly. The mounting bottom ring 31, the mounting slider 33 and the positioning mounting ring 2 are installed together by the mounting bolts 34, so that the sleeve structure 3, the clutch plate 1 and the positioning mounting ring 2 form a whole, ensuring the stability of the clutch plate 1 during use. In addition, the mounting bottom ring 31 and the extension sleeve 35 and the transmission spline shaft 4 are prevented from wobble, so that the clutch plate 1 is prevented from wobble.
[0024] like Figure 3 and 4 As shown, a weight-reducing groove 37 is provided inside the extension collar 35, and ventilation grooves 36 distributed in a circumferential array are provided on the extension collar 35 at the positions corresponding to the weight-reducing groove 37.
[0025] The ventilation slots 36 are staggered, and the position of the weight reduction slot 37 inside the extended collar 35 matches the transmission spline shaft 4.
[0026] The ventilation slot 36 is connected to the weight reduction slot 37, and the bottom surface of the ventilation slot 36 is inclined towards the weight reduction slot 37.
[0027] It should be noted that the extension collar 35 installed on the mounting base ring 31 is used to extend the mounting base ring 31 inside the clutch plate 1. By having a spline groove that matches the transmission spline shaft 4 in both the mounting base ring 31 and the extension collar 35, the extended spline sleeve formed by the mounting base ring 31 and the extension collar 35 has a stronger anti-sway effect.
[0028] Based on this, since the clutch plate 1 achieves the transmission effect through the contact and separation of the clutch plate 1 and the flywheel during use, when the clutch plate 1 separates from the flywheel, the clutch plate 1 and the sleeve structure 3 will have a large moment of inertia. By opening a weight reduction groove 37 in the extension collar 35, the weight of the extension collar 35 is reduced, thereby reducing the moment of inertia of the sleeve structure 3.
[0029] On the other hand, by opening a ventilation groove 36 on the outer contour corresponding to the weight reduction groove 37 on the extension collar 35, and by connecting the ventilation groove 36 with the weight reduction groove 37, and by the staggered distribution of the ventilation groove 36, and by the bottom surface of the ventilation groove 36 tilting outward toward the weight reduction groove 37, the air inside the extension collar 35 and the air outside the extension collar 35 can be exchanged as the clutch plate 1 rotates, thereby achieving the effect of cooling the extension collar 35, and also having a cooling effect on the transmission spline shaft 4.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
