Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clutch devices, in particular to a motorcycle clutch separation structure. Background Technique
[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed on the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. During the driving of the motorcycle, the driver can control the motorcycle clutch pull rod as needed to temporarily separate or gradually engage the engine and the gearbox, so as to cut off or transmit the power input from the engine to the transmission. In the prior art, since the motorcycle clutch is exposed outside, when the motorcycle reverses towards the side of the clutch, it is easy to damage the outer shell of the clutch, and there is a lack of buffer protection for the outside of the clutch to further protect the clutch.
[0003] For example, a disclosed motorcycle clutch structure in the authorized patent document with the application number CN201920411684.2 belongs to the technical field of motorcycles. It solves the technical problem of the poor service life of the existing motorcycle clutch structure. The motorcycle clutch structure of this patent includes a driven disk and a driven seat. The surface of the driven seat has several axially extending columns. The columns penetrate through the driven disk and a limiting disk is arranged at the top of the columns. A clutch spring is arranged between the limiting disk and the driven disk. An annular gasket is abutted between the end of the clutch spring and the driven disk. The annular gasket is sleeved on the periphery of the columns. The motorcycle clutch structure of this patent can ensure a longer service life of the clutch driven disk.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a motorcycle clutch separation structure, including:
[0025] External housing 1;
[0026] And a clutch mechanism 2 provided inside the external housing 1;
[0027] A buffer member 3 installed on one side of the external housing 1 for protecting the clutch mechanism 2;
[0028] The buffer member 3 includes a sleeve 31 fixedly installed on the surface of the external housing 1. A plurality of first springs 32 are clamped on one side of the sleeve 31. One end of the plurality of first springs 32 is clamped with a buffer cylinder 33. And dampers 34 are movably sleeved inside the plurality of first springs 32. The plurality of dampers 34 are all installed between the surface of the sleeve 31 and the inner wall of the buffer cylinder 33. A slider 30 for guiding the movement of the buffer cylinder 33 is provided on the surface of the sleeve 31.
[0029] The slider 30 includes a plurality of spheres 301 embedded in the surface of the sleeve 31. The surfaces of the plurality of spheres 301 are in contact with the inner wall of the buffer cylinder 33. And guide grooves 302 for the spheres 301 to roll are provided on the inner wall of the buffer cylinder 33;
[0030] In this embodiment, when the motorcycle tilts towards the clutch side, the protective ring sleeve 4 is first impacted. Since the protective ring sleeve 4 is a high-temperature resistant rubber sleeve, it provides initial buffering. At the same time, it pushes the buffer cylinder 33 to slide on the sleeve 31. The movement of the buffer cylinder 33 will compress a number of first springs 32 to absorb the impact force. And a damper 34 is arranged inside the first spring 32 to relieve the rebound deformation of the first spring 32, thereby relieving the impact force. The movement of the buffer cylinder 33 will cause the guide groove 302 to push the sphere 301 to rotate, which has a guiding effect on the sliding of the buffer cylinder 33, and further protects the clutch mechanism 2 inside the outer housing 1.
[0031] One side of the buffer cylinder 33 is fixedly installed with a protective ring sleeve 4;
[0032] Specifically, the protective ring sleeve 4 is first impacted. Since the protective ring sleeve 4 is a high-temperature resistant rubber sleeve, it provides initial buffering.
[0033] The clutch mechanism 2 includes an output shaft 21, and a clutch outer hub 22 movably sleeved on the surface of the output shaft 21. A clutch inner hub 23 is engaged with the tooth portion on the surface of the output shaft 21. One end of the output shaft 21 is threadedly installed with a fixing nut 24 for fixing the clutch inner hub 23. A number of steel sheets 25 are engaged with the tooth grooves on the surface of the clutch inner hub 23, and a number of friction plates 26 are engaged with the tooth grooves on the surface of the clutch outer hub 22. The number of steel sheets 25 and the number of friction plates 26 are alternately stacked to form a clutch disc. One side of the clutch inner hub 23 is integrally processed with three columns 27. The surfaces of the three columns 27 are movably sleeved with a pressure plate 28. One side of the pressure plate 28 is clamped with three second springs 5. One end of the three second springs 5 is clamped with a contact bolt 29, and the contact bolt 29 is threadedly installed with one end of the column 27;
[0034] It should be noted that the outer edge of the friction plate 26 has serrations engaged with the tooth grooves on the surface of the clutch outer hub 22. When the clutch outer hub 22 rotates, the clutch inner hub 23 is not affected. And the inner edge of the steel sheet 25 has serrations that can be engaged with the clutch inner hub 23. The rotation of the clutch inner hub 23 does not affect the clutch outer hub 22. Since both the steel sheet 25 and the friction force can slide along the output shaft 21, when the steel sheet 25 and the friction plate 26 are tightly attached, the friction force gradually increases and becomes a whole and operates simultaneously. When the pressure plate 28 is pushed to deform the second spring 5, the steel sheet 25 and the friction force are separated, and the engine power can only drive the clutch outer hub 22 to rotate.
[0035] The protective ring sleeve 4 is set as a high-temperature resistant rubber sleeve;
[0036] Among them, the high-temperature resistant rubber sleeve can maintain the stability of its physical and chemical properties in a high-temperature environment. Usually, it can withstand a relatively high temperature range. For example, some silicone sleeves can withstand temperatures above 200 °C, and even some products can work at higher temperatures without damage.
[0037] A number of dampers 34 are provided as high-temperature resistant dampers 34;
[0038] Among them, the high-temperature resistant damper 34 is used to reduce the vibration and impact of the equipment, and improve the stability and service life of the equipment.
[0039] When the motorcycle tilts towards the clutch side, the protective ring sleeve 4 is first impacted. Since the protective ring sleeve 4 is a high-temperature resistant rubber sleeve, it provides initial buffering. At the same time, it pushes the buffer cylinder 33 to slide on the sleeve 31. The movement of the buffer cylinder 33 will squeeze a number of first springs 32 to compress, adsorbing the impact force. And the damper 34 is arranged inside the first spring 32 to relieve the rebound deformation of the first spring 32, thereby relieving the impact force. The movement of the buffer cylinder 33 will cause the guide groove 302 to push the sphere 301 to rotate, which has a guiding effect on the sliding of the buffer cylinder 33, further protecting the clutch mechanism 2 inside the outer housing 1. Among them, the outer edge of the friction plate 26 has saw teeth that mesh with the tooth grooves on the surface of the clutch outer hub 22. When the clutch outer hub 22 rotates, the clutch inner hub 23 is not affected. And the inner edge of the steel sheet 25 has saw teeth that can mesh with the clutch inner hub 23. The rotation of the clutch inner hub 23 does not affect the clutch outer hub 22. Since both the steel sheet 25 and the friction force can slide along the output shaft 21, when the steel sheet 25 and the friction plate 26 are tightly attached, the friction force gradually increases and they operate as a whole. When the pressure plate 28 is pushed to deform the second spring 5, the steel sheet 25 and the friction force are separated, and the engine power can only drive the clutch outer hub 22 to rotate.
[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
