The invention relates to a clamping jaw (1) for clamping a wheel rim, comprising a main body (2) extending in a longitudinal orientation (L). The main body includes: a connection portion (22) configured to be connected to a head of the wheel holding unit; a base portion (21) extending along a longitudinal orientation; a first abutment wall (23) extending from the base portion along a clamping orientation (R); a second abutment wall (24) extending from the base portion in a spacing direction (VA) along the clamping orientation and longitudinally spaced from the first abutment wall by a working distance (DL); an abutment surface (251) longitudinally interposed between the first abutment surface and the second abutment surface and comprising a first portion (251A) and a second portion (251B, 251C) disposed in a raised position relative to the first portion in a spaced-apart direction of the clamping orientation to contact a wheel rim. The second portion is spaced apart from the first abutment wall along the longitudinal orientation by a first abutment distance (D1) greater than 30% of the working distance.

    本发明涉及一种用于夹紧车轮轮辋的夹爪(1),包括沿着纵向取向(L)延伸的主体(2)。主体包括:连接部分(22),被构造为连接至车轮保持单元的头部;基座部分(21),沿着纵向取向延伸;第一抵接壁(23),从基座部分沿着夹紧取向(R)延伸;第二抵接壁(24),从基座部分沿着夹紧取向在间隔开方向(VA)上延伸并且与第一抵接壁纵向间隔开工作距离(DL);抵接表面(251),纵向介于第一抵接表面与第二抵接表面之间,并且包括第一部分(251A)和第二部分(251B、251C),该第二部分在夹紧取向的间隔开方向上设置在相对于第一部分的提升位置以与车轮轮辋接触。第二部分沿着纵向取向与第一抵接壁间隔开大于工作距离的30%的第一抵接距离(D1)。
