Abstract:
The invention relates to a functional unit (100) for a brake release device, having a recess (111) for receiving a pump assembly (113) and an actuating-cylinder seat (119) for receiving an actuating-cylinder arrangement (400), wherein the functional unit (100) is in the form of a single-piece functional block in which the actuating cylinder seat (119), the recess (111) and multiple ducts (150, 160, 170, 171, 172, 180, 190) forming a conduit system for a hydraulic medium are provided. The invention further relates to a brake release device having a functional unit of this kind.
Abstract:
The invention relates to an electrohydraulic brake release device (1) comprising an actuating cylinder arrangement (400), a tank module (300) for receiving a hydraulic medium, an electric drive unit (200) and a functional unit (100) having a pump assembly (113). The pump assembly (113) is arranged in a recess (111) provided in the functional unit (100), which recess is in communication with the tank module (300), is functionally connected to the actuating cylinder arrangement (400) by way of a conduit arrangement (150, 160, 170, 171, 172, 180, 190) and by way of a bearing carrier cover (115) is sealed off from a dry-running drive motor (210, 211) of the electric drive unit (200). The invention further relates to a brake system comprising a brake release device of this kind.
