Publication number: 20130205940Abstract: An eccentric bearing for an electrohydraulic piston pump assembly of a vehicle brake system includes a shaft which can be driven in rotation about its axis, a bearing ring which is eccentric relative to the shaft, and rolling bodies arranged between the bearing ring and the shaft. The rolling bodies have different diameters corresponding to a varying width of a gap between the bearing ring and the shaft. When the shaft is driven in rotation, an eccentricity of the bearing ring circulates around the shaft at half of the rotational speed of the shaft and drives pump pistons. The pump pistons bear at the outside against the bearing ring so as to perform a reciprocating movement.Type: ApplicationFiled: March 10, 2011Publication date: August 15, 2013Applicant: Robert Bocsh GmbHInventors: Juergen Haecker, Norbert Alaze

Publication number: 20130199320Abstract: An eccentric bearing for an electrohydraulic piston-pump assembly of a vehicle brake system includes a shaft configured to be driven rotationally about its axis, a bearing ring eccentric relative to the shaft, and, in a gap between the bearing ring and shaft, rolling bodies with different diameters according to a differing width of the gap. When the shaft is rotationally driven, an eccentricity of the bearing ring circulates the shaft more slowly than the rotational speed of the shaft and drives a reciprocating movement of pump pistons which bear against the bearing ring. To ensure that the rolling bodies roll on and circulate the shaft, a radial elasticity loads the rolling bodies with prestress against the shaft and bearing ring. The prestress is caused by an undersize of the bearing ring or by an elastic ring on the shaft, on at least one rolling body or in the bearing ring.Type: ApplicationFiled: March 10, 2011Publication date: August 8, 2013Applicant: Robert Bosch GmbHInventors: Juergen Haecker, Norbert Alaze

Publication number: 20130199319Abstract: An eccentric bearing for an electrohydraulic piston pump assembly of a vehicle brake system includes a shaft configured to be driven in rotation about its axis, a bearing ring eccentric relative to the shaft, and rolling bodies between the bearing ring and the shaft. The rolling bodies have different diameters corresponding to a varying width of a gap between the bearing ring and the shaft. When the shaft is driven in rotation, an eccentricity of the bearing ring circulates around the shaft at half of the rotational speed of the shaft and drives pump pistons, which bear against the bearing ring, to perform a reciprocating movement. A resiliently elastic, closed annular steel band surrounds the rolling bodies and loads the rolling bodies inwardly against a circumference of the shaft. The steel band ensures that the rolling bodies roll on the shaft when the shaft is driven in rotation.Type: ApplicationFiled: March 10, 2011Publication date: August 8, 2013Applicant: Robrt Bosch GmbHInventors: Juergen Haecker, Norbert Alaze

Publication number: 20130195390Abstract: An eccentric bearing for an electrohydraulic piston pump assembly of a vehicle brake system includes a shaft configured to be driven in rotation about its axis, a bearing ring which is eccentric relative to the shaft, and rolling bodies between the bearing ring and the shaft. The rolling bodies have different diameters corresponding to a varying width of a gap between the bearing ring and the shaft. When the shaft is driven in rotation, an eccentricity of the bearing ring revolves around the shaft at half of the rotational speed of the shaft and drives pump pistons to perform a reciprocating movement. A rolling body cage is open between the two largest rolling bodies. The rolling body cage loads the rolling bodies into the tapering gap and ensures that the rolling bodies revolve on the shaft when the shaft is driven.Type: ApplicationFiled: March 10, 2011Publication date: August 1, 2013Applicant: Robert Bosch GmbHInventors: Juergen Haecker, Norbert Alaze
