摘要： PURPOSE:To reduce thermal distorsion and manufacturing and assembling processes by dividing a friction material of sintered alloy into a plurality of segments having the same shape and by welding them onto a steel board via a positioning means. CONSTITUTION:Raw material compound of bronze friction material is uniformly mixed, poured in a metal mold and pressed to form molded elements 1 having the same shape. The molded elements 1 are fit on a copper-plated steel board 3 in parallel arrangement so that two projections a formed in position on the back face of each of the molded elements 1 are engaged in corresponding mounting recesses 3a on the board 3, and is thereafter sintered in the non-oxidative atmosphere by the ordinary method to provide a brake pad. Smaller segments of the friction material of sintered alloy will provide lower effect of a bimetal, namely, less distorsion, but many segments are the cause for trouble of many manufacturing processes. The reasonable number of the segments is two to five. A suitable spacing between each segment may be 1 to 3 millimeters.
摘要翻译：目的：通过将烧结合金的摩擦材料分成具有相同形状的多个部分并通过定位装置将其焊接到钢板上，来减少热变形和制造和组装过程。构成：将青铜摩擦材料的原料化合物均匀混合，倒入金属模具中并压制成具有相同形状的模制元件1。模制元件1平行地装配在镀铜钢板3上，使得形成在每个模制元件1的背面上的位置的两个突起a接合在板3上的对应的安装凹部3a中，并且是然后通过常规方法在非氧化性气氛中烧结以提供制动衬块。烧结合金的摩擦材料的较小部分将提供双金属的较低的效果，即较少的变形，但是许多部分是许多制造过程的麻烦的原因。合理数量的细分是2到5。每个片段之间的适当间隔可以为1至3毫米。

摘要： PURPOSE:To restrain the thermal distortion of a friction pad effectively at the time of production and use by selecting the joint area between a steel base plate and a frictional material piece made of sintered alloy to be 25-75% as wide as the area of the one side of the frictional material piece. CONSTITUTION:Raw material components of bronze for frictional material are uniformly mixed to fill a metal mold, and a shaped body 1 is obtained by the pressure of about 2-6ton/cm . For the frictional raw material, all bronze materials conventionally used are available. Then, after joint-preventive agent is applied or arranged on a non-joint part area 5 between a steel base plate 3 previously gilt with copper or copper alloy of about 10-20mum and the shaped body 1 on the steel base plate 3, the shaped body 1 is placed, and sintered in a non- oxidization atmosphere. The extent of the area 5 is selected so that the area of the joint part 7 between the shaped body 1 and the steel base plate 3 may be within the range of 25-75% of the whole area of the shaped body 1.

摘要： PROBLEM TO BE SOLVED: To secure large torque capacity and improve abrasion resistance by selecting a main component element and a minor component element forming the contact surface of a non-driving member and a driving member and maintaining the coefficient of dynamic friction to a specified value or more. SOLUTION: A wet friction contact device is constituted so that the coefficient of dynamic friction of a contact surface may be 0. 2 or more in a state that fluid is interposed between a non-driving member and a driving member. At this time, the contact surface of the one member contains a main component element and the contact surface of the other member is formed by a mixture or an alloy of the main component element and at least one kind of minor component element having the value of free energy which is smaller than the value of free energy of the main component element. The main component element and minor component element are selected among values of free energy. For instance, if Cu is adopted as the main component element and Zn whose value of free energy is smaller than Cu is adopted as the minor component element, Zn is easy to be oxidized, CU is considered to be led to agglutination because oxidation of Cu is suppressed and improvement of the coefficient of dynamic friction is made possible.

摘要： PROBLEM TO BE SOLVED: To secure high coefficient of friction and to improve friction characteristic while maintaining the characteristics of an Al-base sintered friction material, that is, excellent corrosion resistance to oil and lightweight. SOLUTION: This material consists of a base material composed of Al or Al alloy, hard grains contained in the base material and containing at least either of Al2 O3 , and SiO2 , solid lubricant grains contained in the base material, and CaF2 grains contained in the base material. Although the CaF2 grains are disintegrative grains, they are relatively hard, and, by combining them with the hard grains and the solid lubricant grains, the friction coefficient can be increased and also its stability can be improved.
