Description

TECHNICAL FIELD

[0001] The utility model relates to a loader gearbox technical field, concretely relates to 3 ton loader gearbox inner clutch plate. BACKGROUND

[0002] The clutch plate is an indispensable transmission part of the loader gearbox, which realizes the function of power transmission or interruption of power transmission by means of axial compression force; when the axial force compresses the clutch plate, the clutch plate transmits power through friction force, and no torque is transmitted when there is no axial force. The existing clutch plate in the gearbox of the 3-ton loader generally adopts two friction plates with flat surfaces and sintered friction material on the surface of the clutch plate, and the driving plate transmits power to the driven plate through friction force. The defects are: the surface friction material of the friction plate will gradually wear out during use until it eventually fails, the service life of the friction plate cannot completely cover the service life of the gearbox assembly, which makes the friction plate of this structure actually a maintenance consumable that needs to be replaced when a certain period of use is reached, which not only increases the maintenance cost, but also affects the work efficiency. SUMMARY

[0003] The utility model aims at providing a 3-ton loader gearbox inner clutch plate which is simple and compact in structure, low in maintenance cost, long in product service life and efficient in operation, and solves the problem of the existing technology that the clutch plate in the gearbox needs to be replaced when a certain period of use is reached, thereby increasing the maintenance cost and affecting the work efficiency.

[0004] To achieve the above purpose, the 3-ton loader gearbox inner clutch plate of the utility model comprises a driving plate 1 and a driven plate 2; the driving plate 1 and the driven plate 2 are both provided with a tooth-shaped protruding structure on a circular surface, and the two contact surfaces transmit torque through circular tooth-shaped meshing, the tooth-shaped protrusion and the friction plate are of an integral type, the outer ring of the driving plate 1 is meshed with the clutch input gear, and the inner ring is not meshed, the inner ring of the driven plate 2 is meshed with the clutch output gear, and the outer ring is not meshed.

[0005] The 3-ton loader gearbox inner clutch plate with the above structure adopts a clutch plate with tooth surface contact structure, and has the following technical features and advantages:

[0006] 1. Unlike the friction clutch plate of the prior art, it does not need to sinter friction material on the surface of the main transmission clutch plate, and does not transmit torque through friction force, but transmits torque through tooth surface meshing, which is simple and compact in structure, long in service life, does not need to be replaced before the whole machine is scrapped, low in maintenance cost and high in transmission efficiency;

[0007] 2. The surface of the clutch disc in this structure is not flat. Both sides of the contact surface have toothed protrusions, which transmit torque through the meshing of the round toothed protrusions. The toothed protrusions and the friction disc are integral, consisting of a main transmission clutch disc and a driven clutch disc. The design can save clutch space and can also be directly interchanged with the original friction disc, making it highly operable.

[0008] 3. This clutch plate structure provides precise and stable torque transmission, making it suitable for various harsh working conditions and also applicable to high-end gearboxes. Attached Figure Description

[0014] Figure label: Active piece 1, Driven piece 2. Detailed Implementation

[0015] The following detailed description, in conjunction with the accompanying drawings, provides a further detailed description of a specific embodiment of the clutch plate inside the gearbox of the 3-ton loader of this utility model.

[0016] Figures 1-5 As shown, the clutch disc inside the gearbox of the 3-ton loader of this utility model includes a driving disc 1 and a driven disc 2; both the driving disc 1 and the driven disc 2 are provided with toothed protrusions on their circular surfaces, and the two sides of the contact surface transmit torque through the meshing of the circular teeth. The toothed protrusions and the friction disc are integral. The outer ring of the driving disc 1 meshes with the clutch input gear, and the inner ring does not mesh. The inner ring of the driven disc 2 meshes with the clutch output gear, and the outer ring does not mesh.

[0017] When the clutch needs to transmit torque, the round end faces of the driving piece 1 and the driven piece 2 are in close contact, and the torque transmission can be performed; when the clutch needs to cut off the torque transmission, the driving and driven clutch pieces are separated and idled respectively. Thus, the functional requirements can be met. As for the connection of the clutch piece in the clutch and the rest of the functional components, and how to separate, various ways can be used, which are the conventional techniques known by those skilled in the art and will not be described here.

[0018] The tooth surface contact clutch piece used in the clutch in the gearbox of the 3-ton loader can be installed inside the gearbox, no sintering friction material is used, the tooth surface meshing structure is used to transmit torque, the service life is long, and replacement is not needed before the whole machine is scrapped; the clutch piece transmission of the structure is accurate and stable, is suitable for various harsh working conditions, can save user maintenance cost, improves the economy of the gearbox, and can also be used for high-end gearboxes.
