Description

Technical Field

[0001] This utility model relates to the field of friction braking structure technology, specifically to a friction plate with a partition structure. Background Technology

[0002] Friction materials are widely used in brakes, clutches, and friction transmission devices in various transportation vehicles (such as automobiles, trains, airplanes, and ships) and various machinery and equipment. In braking devices, the frictional properties of friction materials are utilized to convert rotational kinetic energy into heat energy and other forms of energy, thereby enabling the transmission device to brake.

[0003] Given the increasing demands for environmental protection and safety in modern society, developed countries in the global automotive industry have rapidly carried out research and development of non-asbestos friction materials, and have successively launched non-asbestos semi-metallic friction materials, sintered metallic friction materials, fiber-reinforced or polymer-bonded friction materials, composite material friction materials, ceramic fiber friction materials, and so on.

[0004] Currently, traditional friction plates have poor assembly performance and low assembly precision. They also have a low coefficient of friction, resulting in rapid product wear. Furthermore, the friction discs have poor heat dissipation performance, failing to effectively dissipate the generated heat in a timely manner, thus reducing the service life of the friction plates. Summary of the Invention

[0005] This invention primarily addresses the shortcomings of existing technologies by providing a friction plate with a partition structure. This friction plate features a simple structure, excellent heat dissipation, and high operational stability. Through the design of the partition and oil passages, effective separation, lubrication, and heat dissipation between the friction plates are achieved, significantly improving the performance and lifespan of mechanical components such as clutches. It not only extends the service life of the friction plate but also optimizes its heat dissipation performance.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0007] A friction plate with a partition structure includes a partition. The outer circumference of the partition has several positioning flanges, each with a positioning notch. Paper-based friction plates are provided at both ends of the partition, and a copper-based sintered sheet is positioned between the paper-based friction plates and the partition. The paper-based friction plate includes an internal toothed steel sheet. One end of the internal toothed steel sheet is firmly sintered to the copper-based sintered sheet, and the other end of the internal toothed steel sheet has a paper-based liner firmly bonded to it.

[0008] The outer circumference of the partition plate is provided with several positioning flanges for fixing and positioning the friction pad assembly. The positioning flanges are provided with positioning notches to facilitate alignment and installation with other components.

[0009] Preferably, the internal toothed steel sheet is provided with an internal toothed ring. The internal toothed steel sheet has an internal toothed ring inside, which enhances mechanical strength and load-bearing capacity.

[0010] Preferably, the internal gear ring and the paper-based liner are provided with a plurality of oil passage holes distributed in an annular pattern at equal intervals. The oil passage holes further optimize the circulation of lubricating oil.

[0011] Preferably, the number of positioning flanges is 4, of which 3 positioning flanges are distributed at equal intervals of 120 degrees, and the other positioning flange is distributed at 90 degrees and 30 degrees to the left and right adjacent positioning flanges, respectively.

[0012] Preferably, the paper-based liner is provided with oil channels, which are spiral grooves, parallel grooves, radial grooves, waffle grooves, or circular arc grooves. This is used to optimize the distribution of lubricating oil.

[0013] This invention can achieve the following effects:

[0014] This invention provides a friction plate with a partition structure, which, compared with existing technologies, features a simple structure, good heat dissipation performance, and high operational stability. It consists of multiple friction plates and partition plates arranged in an alternating pattern. The partition plates are typically annular and have oil passages or lubrication channels to improve lubrication conditions between the friction plates. Through the design of the partition plates and oil passages, effective separation, lubrication, and heat dissipation between the friction plates are achieved, significantly improving the performance and lifespan of mechanical components such as clutches.

There are four positioning flanges 9, three of which are evenly spaced at 120-degree intervals, and the third flange is positioned at 90-degree and 30-degree angles to its adjacent flanges on the left and right sides, respectively. Paper-based friction plates 2 are provided at both ends of the partition 1, and the partition 1 and paper-based friction plates 2 are arranged alternately. A copper-based sintered sheet 5 is provided between the paper-based friction plate 2 and the partition 1.

This not only extends the service life of the friction plates but also optimizes their heat dissipation performance.
