Electrohydraulic actuating device having integrated electrical functional elements

Electrohydraulic actuation device with an electric motor and a pump driven by the electric motor for the operation of a hydraulic unit, wherein the hydraulic unit comprises a positioning cylinder, a piston and a piston rod, wherein the piston rod serves as an actuation element and projects outward from a housing,

• wherein the housing comprises a lower housing part and an upper housing part, wherein the upper housing part is separated and sealed off from the lower housing part, wherein the electric motor is housed in the lower housing part, and the hydraulic unit is housed in the upper housing part,
• wherein the housing has at least in an area of the hydraulic unit a lateral enlargement as a local protrusion of the housing at least one side in relation to a longitudinal axis X of the device, beyond the circumference of the positioning cylinder and at least along a height of a stroke of the piston,
• wherein the lateral enlargement allows for electrical functional elements to be housed directly in the upper housing part, laterally adjacent to the hydraulic unit,
• wherein the housing comprises connections or receiving means for the electrical functional elements, and
• wherein the electrical functional elements comprise at least a contact-free, magnetic-induction sensor, which is arranged and configured for position detection of the piston by means of at least a magnet mounted thereon.
