Method and servomotor designed to detect the braking of a vehicle and method of manufacturing such a servomotor

摘要

The method involves using needles (220), where the needles slide in a housing (222) of a master brake cylinder (202) and integrated with a piston (200) of the master brake cylinder by plastic material plate (210). The needles are arranged in parallel with the piston in a manner to reproduce the displacement of the piston, and the displacement of the needles is detected by a sensor (230) e.g. flexible blade interrupter, for detecting the braking of a vehicle.
