Benefits of technology

This patented design simplifies its construction process, reduces costs, stabilizes performance, provides strong bond between different materials like cerium oxide (CeO2) or silicon carbons, ensures stability during use over an extended period of time, has excellent durability against abrasions caused by external factors such as rainwater, snow, etc., and maintains optimal contact force when used properly. It also includes windows that help distribute load evenly across multiple parts, reducing stress concentration and preventing cracks from forming at certain points along their edges. Additionally, it uses a special type called cerumina which increases its strength compared to other types of material due to its unique crystal structures.

Problems solved by technology

This patented describes how an automatic vehicle's clutches work with different materials that can generate excessive temperatures when they start or shift from one mode into another. These conditions may lead to damage on certain components such as bearings used for rotation. To prevent this problem, there are solutions like adding lubricants during manufacturing processes but these methods have limitations due to their effectiveness at reducing frictional forces while also causing wear issues over time.

Abstract

The invention discloses a novel AMT friction plate assembly of a riveted structure. The novel AMT friction plate assembly is mainly composed of a ceramic friction plate (1), a metal substrate A (2) and a metal substrate B (3); the ceramic friction plate (1) is sintered on the metal substrate A (2); and the metal substrate A (2) and the metal substrate B (3) are correspondingly provided with a riveting hole I (5) and a riveting receding hole I (6) which are coaxial, the metal substrate A (2) is riveted on the metal substrate B (3) through rivets I (9), and rivet heads of the rivets I (9) fall into the riveting receding holes I (6) on the symmetrical sides. According to the novel AMT friction plate assembly, metal substrate deformation caused by the fact that the ceramic friction plate is directly sintered on the metal substrate B can be effectively avoided, the friction plate is of a small blocky structure, powder metallurgy pressing of friction materials is achieved on a small-tonnage press, the technological machinability is good, the product percent of pass is high, and manufacturing is convenient.
