- 粉末冶金法で製造されるピストン・シリンダ装置用ピストン本体、特にショックアブソーバピストンであって、一体なピストン本体(6)を有し、このピストン本体がその周面に、一方のピストン端面(4.1)に隣接する領域で、周面から張り出す周方向周設腹部(12)を備えており、この周設腹部に、他方のピストン端面(5.1)にまで延びて平行に離間して並置される縦延設支持腹部(10)が続いており、支持腹部のうち少なくとも一部が両方のピストン端面(4.1、5.1)の間で少なくとも1つの横溝(11.1)を備えており、それぞれ2つの隣接する支持腹部(10)が溝状凹部(11)を限定し、これらの凹部は周設腹部(12)から離れた方の末端が縦方向で開口しており、熱間成形可能なシール材料からなるカフス状シール(9)がピストン本体(6)上に、周設腹部(12)も支持腹部(10)も少なくとも高さの一部にわたってカフス状シール(9)の材料内に一体に形成されるように成形可能であるピストン本体。
- 溝状凹部(11)の深さが、周設腹部(12)に隣接する領域(B)では周設腹部(12)から離れた方の端面(5.1)領域内よりも小さいことを特徴とする、請求項1記載のピストン本体。
- ピストン・シリンダ装置用の一体なピストン本体、特にショックアブソーバピストンを製造するための方法であって、ピストン本体がその周面に、一方のピストン端面(4.1)に隣接する領域で、周面から張り出す周方向周設腹部(12)を備えており、この周設腹部に、他方のピストン端面(5.1)にまで延びて平行に離間して並置される縦延設支持腹部(10)が続いており、それぞれ2つの隣接する支持腹部(10)が溝状凹部(11)を限定し、これらの凹部は周設腹部から離れた方の末端が縦方向で開口しているものにおいて、第1ステップでは焼結性金属冶金粉末から、周設腹部と縦延設支持腹部とを有する圧粉体が加圧され、第2ステップではこの圧粉体がブランク(6.1)へと仕上げ焼結され、第3ステップでは支持腹部(10)の少なくとも一部に、半径方向で案内されるコイニングダイ(14)を用いて冷間成形によって、材料を排除しながら横溝(11.1)が一体に形成され、第4ステップではこうして横溝(11.1)を備えたブランク(6.1)がサイジングダイで加圧することによってその最終形状にサイジングされることを特徴とする方法。
- 半径方向でブランクに加圧可能な少なくとも2つのコイニングダイ(14)が使用され、コイニングダイがそれぞれ少なくとも1つの切刃状コイニング稜を有することを特徴とする、請求項3記載の方法。
- 少なくとも2つのプレス部(I、II)を有するプレス装置(P)が使用され、第1プレス部(I)ではブランク(6.1a)に横溝(11.1)が備えられ、同時に第2プレス部(II)では横溝(11.1)を備えたブランク(6.1b)がサイジングされることを特徴とする、請求項3または4記載の方法。
