Abstract: An electromechanical brake apparatus includes a housing supporting an inboard brake pad and an oppositely facing outboard brake pad for selective frictional contact with a rotor interposed longitudinally therebetween. The housing includes a mechanism cavity located longitudinally between the inboard pad and a motor having a motor output shaft. An adjuster ramp assembly indirectly receives torque from the motor. A spindle is operatively connected with the adjuster ramp assembly to indirectly receive torque from the motor therethrough. A leading ramp assembly is configured to transmit applied torque from the motor to the adjuster ramp assembly. The leading ramp assembly receives stepped-up torque from the motor via the motor output shaft and a ball thrust bearing at least partially located radially between the motor output shaft and an actuator ramp of the leading ramp assembly.

Abstract: An electromechanical brake apparatus includes a housing supporting an inboard brake pad and an oppositely facing outboard brake pad for selective frictional contact with a rotor interposed longitudinally therebetween. An adjuster ramp assembly indirectly receives torque from the motor unit. A spindle is provided for selectively moving the inboard brake pad longitudinally. The spindle is operatively connected with the adjuster ramp assembly to indirectly receive torque from the motor unit therethrough. A leading ramp assembly is configured to transmit applied torque from the motor unit to the adjuster ramp assembly via at least one ramp ball longitudinally interposed therebetween. A predetermined amount and direction of torque is applied to each of the adjuster ramp assembly and the leading ramp assembly to assist with a selected one of (1) service brake application and (2) service brake release functions. The electromechanical brake apparatus is operative, at different times, for both functions.

Abstract: An electromechanical brake system includes a housing defining a mechanism cavity. An apparatus for force application includes a first piston, including a first piston motivator comprising a first push rod and an actuator. A brake pad is operatively connected to both the first and second pistons for longitudinal driving thereby. A rocker arm is operatively connected to both the first and second pistons for force transmission therebetween. A pivot bearing rotatably supports the rocker arm. The actuator is configured to move selectively longitudinally with respect to the first push rod to move at least a portion of the first piston toward the brake pad. The pivot bearing is maintained in a predetermined longitudinal position as a reaction force is developed between the first piston and the brake pad. The rocker arm transmits at least a portion of the reaction force from the first push rod to the second piston.
