Abstract
An actuation device for a hydraulic actuation system, e.g., a motor vehicle brake or an electrified clutch actuator, may include a connection for an actuation device; a pressure supply device, driven by an electromotor drive, in the form of a piston or double-stroke piston pump; a piston cylinder unit that may be actuated by means of the actuation device; and an electronic control unit. An axis of the piston cylinder unit and an axis of the pressure supply device may be arranged in parallel.
Claims19
An activation device for a hydraulic activation system of a vehicle, the activation device including:
- a connection for an actuation device in the form of a brake pedal or a clutch activation device,
- a pressure supply device, driven by an electric motor drive in the form of a double-stroke piston pump, wherein the electric motor drive adjusts the double-stroke piston pump directly or via a transmission gear unit,
- a piston-cylinder unit enabled to be activated by the activation device and hydraulically connected to a pressure medium reservoir vessel, and
- an electronic control unit,
- wherein the electric motor drive is arranged underneath a longitudinal axis of the piston-cylinder unit,
- wherein both the piston-cylinder unit and the pressure supply device are arranged in a first housing produced in a continuous casting process, and
- wherein the transmission gear unit comprises an epicyclic ball transmission in the form of a spindle drive.
An activation device for a hydraulic activation system of a vehicle, the activation device including:
- a connection for an activation device, in the form of a brake pedal or a clutch activation device,
- a pressure supply device, driven by an electric motor drive, in the form of a piston pump or a double-stroke piston pump, wherein the electric motor drive adjusts the piston of the piston pump or double-stroke piston pump directly or via a transmission gear unit,
- a piston-cylinder unit enabled to be activated by the activation device and hydraulically connected to a pressure medium reservoir vessel, and
- an electronic control unit,
- wherein a connection element is enabled to be plugged into the control unit in a horizontal plugging direction, and wherein the connection element is arranged above the piston-cylinder unit,
- wherein the connection element is arranged to be plugged into the control unit above a first housing, wherein the first housing accommodates the piston-cylinder unit and the piston of the pressure supply device, and
- wherein the connection element is unpluggable from the control unit in a horizontal direction towards an axis of the piston-cylinder unit and away from the control unit.
