Master brake cylinder arrangement for hydraulic brake system of motor vehicle, has coupling extension fastened at transfer unit and connected with force input piston for common movement in force transmission manner

摘要

The arrangement (10) has two adjacent cylinder boreholes (18, 20) provided in a housing (12), and two piston arrangements (22, 24) displaceably received along borehole longitudinal axes (A, B) in the boreholes. The piston arrangements limit pressure chambers (26, 28) with the housing, where the chambers are connected fluidly with a hydraulic brake system. A transfer unit (44) is arranged between the piston arrangements and a force input piston (54), where a coupling extension (48) is fastened at the unit and connected with the piston for common movement in a force transmission manner.
