In particular, the eccentric assembly for the pump of the ABS system and the pump for the ABS system

摘要

The present invention relates to a radial piston pump used in, for example, an ABS system in a vehicle. The pump has, in a known type of construction, a drive shaft having an eccentric section in which a rolling bearing which rotates eccentrically about the rotational axis of the shaft as a whole is seated. An object of the present invention is to propose an eccentric assembly having a high reliability in operation and a corresponding pump. To this end, An eccentric shaft section (4) for eccentrically rotating about a main rotational axis (H), comprising: an eccentric shaft section (4) for providing or supporting an internal track (9); There is proposed an eccentric assembly 1 having a rolling bearing device 7 which is disposed on an eccentric shaft section 4 and defines an eccentric axis E, 7 comprises a plurality of rotating bodies 12 and one outer track device 8 which provides an outer track 10 for the rotating body 12 and which rotates the rotating body 12 Has a rolling motion on the inner orbit 9 and the outer orbit 10 in the rotary chamber 11 and the eccentric assembly also has a supporting element 17 and a supporting surface 18 as supporting partners, The support element 17 is operatively resting on the support surface 18 and the support partners together form an axial support of the eccentric shaft section 4 on the housing 5, And another support partner is supported on the eccentric shaft section 4 In this case, the support surface 18 is arranged fixed to the housing.;
