Abstract

The invention discloses a semimetal ceramic matrix air disc brake pad of an air disc braking system for heavy-duty freight cars and a production method thereof, wherein the production flow is as follows: sequentially weighing and putting 10 nonmetal assorted fibre, 35-40 metal fibre, 20 or 25 of friction performance regulator, 15-25 of vitrified bond, 5-10 of elastic toughening agent and 10 of filler into a high-speed mixer to mix uniformly, then carrying out pressing and thermocuring treatment according to a dry once-through molding technique of the traditional resin matrix friction materials, finally machining, ceramic processing, inspecting and packaging. The semimetal ceramic matrix air disc brake pad manufactured according to the technique has large braking torque, comfortable emergency braking, small heat fading and simple production technology, is environmental friendly, is particularly suitable for air disc brakes of the heavy-duty freight cars, and has wide market prospect.

Description

technical field The invention relates to an air pressure disc brake pad, in particular to a semi-metal ceramic based brake pad used in an air pressure disc brake system of a heavy-duty truck, and also relates to a preparation method of the brake pad. Background technique From a technical point of view, 1. Due to its structural characteristics, the heat generated by drum brakes is difficult to dissipate during work. Because most of the brake discs of pressure disc brakes are exposed to the air, heat exchange is easy, and the temperature rises during work. Lower, less thermal recession. 2. When the required braking torque is the same, the pneumatic disc brake has a much smaller overall size than the drum brake. Therefore, it brings convenience to the layout of the whole vehicle; and because its mass, especially the mass of the rotating part, is very small more, and the imbalance is much smaller. It can significantly improve the comfort, smoothness and handling stability of t...
