Problems solved by technology

[0005] The purpose of the present invention is to overcome the fact that existing tread cleaning tile materials, especially friction body materials, cannot effectively eliminate the defects of the wheel tread when they are in contact with the wheel tread, and improve the state of the wheel tread, which in turn leads to a low adhesion coefficient between the wheel tread and the rail , the wheels are prone to idling and slipping defects during the operation of the train, and then provide a friction material, a friction body, a cleaning tile containing the friction body, and a preparation method and application of the cleaning tile

Abstract

The invention relates to the technical field of friction materials, in particular to a friction material, a friction body, a cleaning tile comprising the friction body, and a preparation method and application of the cleaning tile. The friction material provided by the invention is prepared from the following raw materials in parts by weight: 10-14 parts of an adhesive, 19-24 parts of metal fibers, 8-11 parts of non-metal fibers, 45-50 parts of a tackifier, 4-10 parts of elastic particles and 4-7 parts of a lubricant. The friction material provided by the invention is applied to the sweeping tile, so that the wheel tread defects can be effectively eliminated, the tread roughness is increased, the adhesion coefficient between the wheel tread and a steel rail is further improved, and the phenomena of idling and slipping of wheels in the running process of a train are prevented.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a friction material, a friction body, a cleaning tile containing the friction body, and a preparation method and application of the cleaning tile. Background technique [0002] The braking system of railway rolling stock and urban rail transit vehicles generally uses tread braking (brake shoe braking) for train braking. Parking brake. This braking method has a small friction area, and as the speed of the train increases, the tread braking heat load increases, which is likely to cause defects such as abnormal wear, cracks, and peeling of the wheel tread. [0003] With the increase of train running speed, it is difficult for tread brake to meet the braking requirements of high-speed trains, so disc brakes with large friction area and high braking efficiency have been developed. The disc brake can greatly reduce the thermal load and mechanical wear on the wheel tread, a...
