Abstract
The present invention relates to an actuator for an electro-hydraulic braking system of the ‘brake-by-wire’ type comprised of a hydraulic pressure generator or master brake cylinder and a travel simulator, with said master brake cylinder including at least one piston that is operable by an actuating pedal, and wherein a device for detecting a driver's deceleration wish is provided, said device cooperating with said piston and being at least partly arranged in a master brake cylinder housing. To optimize the assembly in terms of packaging, production costs, weight, and function, the present invention discloses that the device for detecting a driver's deceleration wish comprises an annular housing embracing the piston in a radial direction and accommodating signal receiving elements which cooperate with signal transmitting elements mounted on the piston surface.
