Hydromechanical brake motive apparatus

A hydromechanical brake motive apparatus, comprising:

• a reservoir containing hydraulic fluid;
• a power transmission unit for selectively providing at least one of negative and positive pressure to the hydraulic fluid to generate pressurized hydraulic fluid;
• a caliper piston including a piston cavity configured to contain hydraulic fluid and at least a portion of the power transmission unit, the piston cavity being in selective communication with the reservoir via a reservoir passage;
• and
• a motive housing containing at least a portion of each of the reservoir, the power transmission unit, and the caliper piston therein to maintain a closed-loop system for the hydraulic fluid, the motive housing defining a piston bore, and the caliper piston selectively reciprocating longitudinally with respect to the piston bore under influence of pressurized hydraulic fluid from the power transmission unit;
• wherein the reservoir, power transmission unit, and caliper piston are co-located proximate a corresponding brake pad;
• the power transmission unit including;
• a plunger configured for longitudinally reciprocal motion with respect to the piston cavity to selectively reciprocate the caliper piston via pressurization of hydraulic fluid located within the piston cavity;
• a spindle located at least partially within the piston bore, the spindle selectively reciprocating the plunger, the plunger moving longitudinally relative to the spindle;
• and
• a motor for selectively driving the spindle in rotary motion to urge the plunger into the longitudinally reciprocal motion with respect to the piston cavity.
