基油(パラフィン系鉱油、動粘度:75 mm2/s(40℃))に、増ちょう剤(芳香族ジウレア化合物、4,4'-ジフェニルメタンジイソシアネート及びp-トルイジンの反応生成物)、カーボンブラック(一次粒径:10~20 nm)、ポリテトラフルオロエチレン(PTFE、粒度分布における平均粒径:5 μm)、及びその他の添加剤(酸化防止剤、錆止め剤及び耐摩耗剤)を加えて、3本のロールミルで混練して、実施例1及び比較例1の潤滑剤をグリース組成物の形態として調製した。芳香族ジウレア化合物の構造を下記に示す。実施例1及び比較例1の潤滑剤における各成分の含有量を表1に示す。表中、各成分の含有量は、潤滑剤の総質量に対する質量%として示す。
[混和ちょう度の測定試験]
実施例1及び比較例1の潤滑剤の混和ちょう度を、JIS K2220 7に基づき測定した。その結果、実施例1及び比較例1の潤滑剤の混和ちょう度は、いずれも300であった。
実施例1及び比較例1の潤滑剤を、車軸転がり軸受(JTEKT社製、複列アンギュラ玉軸受を有するハブユニット)に封入した。この車軸転がり軸受を、試験車両の前後及び左右の4輪に組み付けした。試験車両の仕様を表2に示す。
