US 2026/0061983 A1 · BRAKE SYSTEM

Abstract

A vehicle includes a chassis, multiple tractive elements coupled with the chassis, and a brake system. The brake system includes a caliper body that defines a sealed inner volume, a piston, a spring, a valve, brake pads, a movable member, and a position sensor. The piston is positioned within the sealed inner volume and divides the sealed inner volume into a first sub-volume and a second sub-volume. The spring is within the first sub-volume and biases the piston to extend. The valve fluidly couples the second sub-volume with a pump. The brake pads are configured to be driven by the piston to engage a brake rotor. The movable member is coupled with the piston and is configured to translate with translation of the piston. The position sensor is operably coupled with the movable member and configured to generate a signal responsive to translation of the piston and the movable member.

Dependent claims

A vehicle comprising:

a chassis;
a plurality of tractive elements coupled with the chassis;
a brake system for at least one of the plurality of tractive elements, the brake system comprising:
a caliper body defining a sealed inner volume;
a piston positioned within the sealed inner volume, the piston dividing the sealed inner volume into a first sub-volume and a second sub-volume;
a spring positioned within the first sub-volume, the spring configured to bias the piston to extend;
a valve configured to fluidly couple the second sub-volume with a pump;
a plurality of brake pads configured to be driven by the piston to engage a brake rotor;
and
a position sensor operably coupled with a movable member, the movable member extending towards the piston, the spring configured to bias movement of the piston such that the movable member is moved towards the position sensor as a braking force is applied.
