Brake System having an Electric Servo Brake

摘要

A brake system includes a master cylinder, an electric servo brake, and an electric motor. The electric motor drives a screw that engages a pair of helical gears which are each mounted on a respective shaft. Each shaft further mounts a gear that meshes with a respective gear rack. The electric servo brake includes a body that defines rails which guide the gear racks. A lever is supported on each end by one of the gear racks, and is connected to a support via a pivot point. The support lies flat against a side of a reaction disk that lies against a push rod that actuates the master cylinder.

1. A brake system comprising:
a master cylinder that defines an axis; and an electric servo brake which includes:
a body that defines a pair of rails running parallel to the axis;a reaction disc;a push rod that acts on the master cylinder;a plunger;a control rod configured to press on the reaction disc via the plunger;a carrier that lies flat against the reaction disc;a pair of gear racks guided in the pair of rails and diametrically opposed relative to the axis, the pair of gear racks configured to slide the push rod to act on the master cylinder via the reaction disk;a pair of gear wheels that meshes with the pair of gear racks;a pair of shafts that supports the pair of gear wheels;a pair of helical gears mounted on the pair of shafts;a screw that engages the pair of helical gears; an electric motor that drives the screw; and
a lever that has two ends lying on the pair of gear racks, and that is connected by a rotary point to the carrier such that an orientation of the lever and an orientation of the carrier are separated from each other.
