Abstract

Technical Field
[0001] The utility model relates to the technical field of friction material structures, in particular to a friction plate braking structure used for a clutch of an air cushion craft. Background Art
[0002] As mechanical devices develop towards high load, high speed and high power, they are used in high and low speed with small torque (motorcycles, etc.), high and low speed with medium torque (automatic cars, etc.), and even high and low speed with large torque (machine tools, ships, construction machinery, agricultural machinery, etc.). This puts forward higher performance requirements for friction devices. Traditional powder metallurgy friction materials can no longer fully meet the requirements of high energy density friction systems; the high cost of carbon / carbon friction materials, the brittleness of ceramic-based friction materials, and the low strength of paper-based friction materials restrict their large-scale promotion and application.

At the same time, the friction coefficient is low, the product loss is fast, and the heat dissipation performance of the friction plate is poor. The heat generated cannot be effectively discharged in a timely manner, resulting in a reduced service life of the friction plate. Therefore, it is urgent and necessary to develop a new type of friction plate that matches the transmission system or brake system, has a long service life and high reliability. It can be used in various types of vehicles, such as automotive automatic transmissions, torque converters, differentials, torque managers, synchronizer rings, motorcycle clutches, and engineering machinery gearboxes.
