Embodiment

[0048] Hereinafter, the present invention will be specifically described by way of examples. However, the present invention is not limited thereto.

[0049] In this example, according to image 3 Friction material raw materials were blended in the indicated compounding amounts to obtain the friction material compositions of Examples 1 to 6 and Comparative Example 1. In addition, the unit of the compounding quantity of each friction material raw material in a table is weight% with respect to the whole friction material composition. In addition, in the column of inorganic friction adjusting material and filler, "untreated" described on the right side of each raw material name indicates that the above-mentioned coating has not been applied, and the fatty acid and metal soap described below the "untreated" The name is the name used for the above-mentioned coating (the numerical value (weight %) described in the column of each example is the material used for coating). This fric...

Abstract

In a non-asbestos friction material including base fibers, a binder, a lubricant, an inorganic friction modifier, a pH adjuster, and a filler as compounding ingredients, the filler and / or the inorganic friction modifier is coated by a fatty acid and / or a metal soap. Aggregation of wear powder generated by friction of the friction material and the material subjected to friction is thereby suppressed, and generation of creep groan is suppressed.

Description

technical field [0001] The present invention relates to, for example, a non-asbestos-based friction material used in a brake device for a vehicle. Background technique [0002] Conventionally, it is known that during the driving of an automatic transmission (AT) vehicle, when the foot brake is used to stop and the brake pedal is slightly released to completely release the brake, due to the creep phenomenon, torque is generated in the direction of travel, accompanied by braking. The shock generated by the change of the relative speed between the block and the brake disc (Rota) is transmitted and radiated to the suspension and the car body, thereby producing an unpleasant abnormal sound, so-called creep tremolo (creep grunt) (or creep noise ( クリープ different sound)). For manual transmission (MT) vehicles, this creep chatter also occurs when the brake is released during a stop by applying the foot brake on a downhill slope. [0003] During the occurrence of this creep chatter, ...
